Description

Lid device and table water jug

The present invention relates to a lid device, in particular for closing a jug container opening of a jug container of a table water jug, wherein the lid device comprises a lid with a filling opening, in particular for filling the jug container when the lid device is in place, and a filling opening lid for closing the filling opening in a closed position, wherein the filling opening lid is displaceable from the closed position into a filling position in which it at least partially releases the filling opening, and vice versa.

Furthermore, the present invention relates to a table water jug comprising a jug container with a jug container opening and a container lid for closing the jug container opening in a closed position.

Table water jugs and lid devices of the type described above are known in a wide variety of designs. Lid devices comprising a lid with a filling opening and a filling opening cover for opening and closing the same serve, in particular, the purpose of filling the table water jug with water without having to remove the lid device. To do so, the filling opening only needs to be opened by moving the filling opening cover from the closed position to the filling position, so that it at least partially exposes the filling opening. With such lid devices, it is then not necessary to remove the entire lid device from the jug container in order to fill it with water.

One problem with conventional lid devices is their often difficult cleanability. Especially when the filling opening cover cannot be separated from the lid or can only be separated with difficulty, the lid device is often difficult to clean. WO 2005/074761 A1 discloses a jug with a container lid. GB 2621594 A discloses a water treatment device.

It is therefore a particular object of the present invention to improve a lid device and a table water jug of the type described above so that they are easier to handle.

This object is achieved according to the invention in a lid device of the type described above in that the lid device comprises an undercut-free lid holding device for holding the filling opening lid on the lid in a holding position in a purely force-fitting manner.

The refinement of a lid device proposed according to the invention makes it possible, in particular, to easily remove the filling opening lid from the lid, for example, for cleaning it. Because the lid holding device is designed without undercuts, it is particularly possible to remove the filling opening lid from the lid regardless of whether it is in the closed position, the filling position, or any other position. Separating the filling opening lid from the lid is thus possible in a simple manner and without laborious disassembly of the lid device. A user can intuitively remove the filling opening lid from the lid and does not require an instruction manual.

It is advantageous if the filling opening cover is designed to be movable from the holding position into a release position, in which the filling opening cover is removed and separated from the lid. In other words, the filling opening cover can be easily removed from the lid and thus separated from it. The lid device can then be cleaned easily, in particular by cleaning the lid and the separated filling opening cover separately. It is advantageous if the filling opening cover is designed to slide on the cover when moving from the closed position to the filling position and vice versa. Such a design enables, in particular, a virtually force-free movement of the filling opening cover on the cover. Thus, for example, it can be moved along the cover by a user without great effort.

According to a further preferred embodiment, it can be provided that the lid device comprises at least one sliding element and at least one sliding surface interacting with the latter, which are arranged or formed on the one hand on the lid and on the other hand on the filling opening lid, and that the at least one sliding element and the at least one sliding surface abut one another when the filling opening lid is moved from the closed position to the filling position and vice versa. Such a lid device enables, in particular, a virtually force-free displacement of the filling opening lid on the lid. In particular, several sliding elements can be provided, for example, two, three, four or even more. In particular, the sliding elements can form the only contact points between the filling opening lid and the lid, so that static and sliding friction forces that must be overcome to move the filling opening lid on the lid are defined solely by the interacting sliding elements and sliding surfaces.

The lid device can be designed in a simple manner if the sliding elements are in the form of sliding projections. In particular, these can be rounded nubs that enable the filling opening lid to slide particularly easily and reliably on the lid.

It is advantageous if the sliding elements are arranged or formed on the filling opening cover. This makes it possible, in particular, to provide one or more sliding surfaces on the cover. The cover itself can thus be designed without any projections, particularly in the area of the sliding surfaces. In other words, there are no sliding elements on the lid in this design.

The sliding surfaces are advantageously flat, allowing the filling opening cover to be moved easily and reliably on the cover.

It is advantageous if the sliding surfaces are arranged or formed on the lid. As already mentioned, this allows the lid to be designed without any protrusions in the area of the sliding surfaces. The sliding surfaces, or one of the sliding surfaces, can, in particular, laterally delimit the filling opening. This makes it possible, in particular, to form a reliable support for the filling opening cover on the lid. The filling opening cover can thus rest on the lid laterally, especially on both sides, of the filling opening, for example, in the closed position.

According to a further preferred embodiment, the lid device can be provided with a locking device for locking the filling opening lid in at least one locking position. A locking device in this sense makes it possible, in particular, to hold, fix, or lock the filling opening lid on the lid in certain positions such that increased force is required to move the filling opening lid out of this position. Such a locking device is advantageous, for example, when the filling opening lid assumes the closed position. This prevents the filling opening lid, which assumes the closed position, from moving when the table water jug is being transported, and the filling opening lid from inadvertently and undesirably exposing the filling opening.

It is advantageous if at least one locking position defines the closed position and/or the filling position. It can also be advantageous in the filling position if the filling opening cover is locked to the lid. This allows, for example, when filling the table water jug, Under a faucet, the filling opening lid can be prevented from sliding back into the closed position by itself. The locking device thus enables improved handling of the table water jug.

It is advantageous if the locking device comprises cooperating first and second locking elements, which are arranged or formed on the lid on the one hand and on the filling opening cover on the other hand, and if the cooperating first and second locking elements engage in a force-locking and/or positive-locking manner in the at least one locking position. A locking device designed in this way makes it possible, in particular in a simple manner, for example purely mechanically, to lock the filling opening cover to the lid in the at least one locking position. This can be achieved by bringing cooperating first and second locking elements into force-locking and/or positive-locking engagement.

Preferably, the first and second locking elements, which interact in the at least one locking position, are engaged by magnetic interaction. Such a configuration has the particular advantage that wear of mechanical locking elements, such as projections and recesses that engage with one another, cannot occur. Locking is achieved by magnetic interaction, for example, by arranging two magnets such that a south pole of one magnet is aligned with a north pole of the other magnet in the locking position. The magnets thus exert a strong force of attraction on one another in the locking position, which must be overcome to unlock. The acting magnetic force is also noticeable to a user, so that such a locking device can also provide a haptic feedback to the user. When handling the lid device, the user can therefore feel whether the filling opening lid is in the locking position or not. It is advantageous if the first and second locking elements are designed in the form of interacting locking projections and locking receptacles. Such locking elements can be easily formed, in particular by molding them onto the interacting components, namely the filling opening cover and the cover.

The lid device can be designed particularly simply and compactly if the sliding elements form locking projections. They can thus perform a dual function. On the one hand, they can simplify and support the movement of the filling opening cover on the lid. On the other hand, they can define one or more locking positions together with other locking elements. As already explained, the sliding elements can be formed in particular on the filling opening cover.

Preferably, at least one locking receptacle in the form of a sliding surface recess is arranged or formed on the lid in the at least one sliding surface. Such a locking receptacle makes it possible, in particular, to accommodate locking projections. A locking position is therefore defined in particular by, for example, a locking projection on the filling opening cover engaging in the locking receptacle. For example, the closed position or the filling position can be predetermined in this way. Such a configuration also enables a locking mechanism that is noticeable to a user, essentially a snapping of the filling opening cover onto the lid in the at least one locking position. If, for example, two locking projections are provided on the filling opening cover, two correspondingly arranged locking receptacles can specify the filling position, and two further locking receptacles can specify the closed position. Alternatively, if four locking projections are provided on the filling opening cover, both a filling position and a closed position can be realized by two locking receptacles which engage with two of the four locking projections in the filling position and with the other two locking projections in the closed position. According to a further preferred embodiment, the lid can comprise a circumferential edge surface, and the edge surface defines stops acting in opposite directions for the filling opening lid in the closed position and the filling position. Such a configuration has the particular advantage that a user can always move the filling opening lid to the stop to open or close the filling opening. This simplifies intuitive handling of a table water jug with such a lid device.

In order to easily prevent the filling opening cover from being pushed off the lid, it is advantageous if the edge surface extends transversely, in particular vertically, away from the at least one sliding surface. The circumferential edge surface thus forms a limit for the movement of the filling opening cover on the lid.

It is advantageous if a contour of the edge surface corresponds to an outer contour of the filling opening cover such that the filling opening cover and the edge surface lie flat against one another in the filling position and/or the closed position. Such a configuration particularly reduces surface forces acting when the filling opening cover strikes the edge surface in an extreme position, for example, in the filling position or the closed position. The filling opening can thus be opened and closed smoothly by sliding the filling opening cover.

According to a further preferred embodiment, the lid holding device can comprise a magnetic holding device for magnetically holding the filling opening lid on the lid in the holding position by means of magnetic force. In particular, the filling opening lid can be held on the lid exclusively by means of magnetic force. Developing a lid holding device in this way makes it easy to remove the filling opening lid from the lid. To do so, the acting magnetic force only needs to be overcome. Due to the lid retaining device's particularly undercut-free design, no other interacting retaining elements need to be disengaged. The filling opening cover can be intuitively removed from the lid by a user. The magnetic retaining device can, in particular, be designed such that, regardless of the relative position of the filling opening cover and the lid, a magnetic holding force is always exerted, so that the filling opening cover is securely held on the lid in any position.

It is advantageous if the magnetic holding device comprises at least two cooperating holding elements, which are arranged or formed on the one hand on the filling opening cover and on the other hand on the lid. The at least two holding elements thus cooperate magnetically to hold the filling opening cover on the lid in the holding position.

Preferably, at least one of the at least two cooperating holding elements is magnetic. In particular, it is designed in the form of a magnet. A further holding element cooperating with a magnetic holding element can also be magnetic, for example in the form of a magnet, or also in the form of a magnetizable element, for example in the form of a metallic element containing iron, cobalt, or nickel, so that, in cooperation with a magnet, a corresponding holding force can act between the two holding elements. In any case, it is conceivable for the magnetic holding device to comprise only a single magnet.

A particularly simple and compact construction of the lid device can be realized in particular by arranging or forming the at least one magnetic holding element on the filling opening lid.

For easy assembly of the cover device, it is advantageous if the magnetic holding element is designed to be rotationally symmetrical with respect to a holding element's longitudinal axis. Thus, there is no preferred direction when such a holding element is received in a corresponding, rotationally symmetrical receptacle for holding on the filling opening cover or on the cover.

To fix the magnetic holding element to the lid device, it is advantageous if it comprises a holding flange that protrudes radially relative to the longitudinal axis of the holding element. In particular, this allows for a positive fixation of the magnetic holding element to the filling opening cover or to the lid.

Advantageously, at least one of the at least two retaining elements is held in a retaining element receptacle. Of course, all retaining elements, in particular the magnetic retaining device, can be held in a suitable retaining element receptacle. The retaining elements can thus be arranged in a particularly protected manner.

To protect the retaining elements from corrosion, especially when they are made of metal elements containing iron, cobalt, or nickel, it is advantageous for the retaining element receptacle to be sealed fluid-tight. For example, it can be sealed by gluing or welding.

The holding device preferably comprises a holding member for holding at least one holding element in the holding element receptacle in a force-fitting and/or positive-locking manner. For example, such a holding member can be screwed to the holding element receptacle to securely hold the at least one holding element therein.

The cover device can be easily assembled if the retaining element and the retaining element receptacle are connected to each other in a snap-fit manner to hold the at least one retaining element. For assembly, for example, the retaining element only needs to be inserted into the retaining element receptacle and the retaining element connected to the retaining element receptacle in a snap-fit manner. in order to reliably hold at least one holding element in the holding element receptacle.

Advantageously, at least one of the at least two retaining elements is designed to be magnetizable. Such a design makes it possible, in particular, to create a magnetic force between such a retaining element and a magnetic retaining element, for example in the form of a magnet. Magnetizable retaining elements have the particular advantage that they can be designed in virtually any desired manner and are also inexpensive to manufacture. The only requirement is that they are magnetizable. This means, in particular, that the retaining element is at least partially made of a material that is attracted to a magnet.

It is advantageous if the at least one magnetizable holding element is at least partially formed from a magnetizable material. In particular, this can be a material containing iron, cobalt, and/or nickel. Such a magnetizable holding element can be of virtually any shape, yet cooperate with a magnet, which forms a magnetic holding element, to hold the filling opening cover and the cover together, particularly through purely magnetic force.

Advantageously, the at least one magnetizable holding element is designed in the form of a holding strip. Such a configuration makes it possible, in particular, to realize a magnetic force between a magnet and the holding strip along an extension thereof. Thus, if a magnetic holding element is arranged at a short distance from the holding strip, the magnetic holding element can be displaced relative to the holding strip because a magnetic interaction is then always present. Thus, the magnetic holding device can be designed, in particular, such that the filling opening cover and the cover can be held in place both in the filling position and in the holding position and in any position between these both extreme positions are held together by magnetic force.

It is advantageous if the retaining strip extends in a displacement direction of the filling opening cover and has a length such that at least one additional retaining element interacts magnetically with the retaining strip in the filling opening position and/or the closed position. The retaining strip, in conjunction with a magnetic retaining element, can thus reliably provide the holding force required to hold the filling opening cover to the cover. The interaction of a magnet and a magnetizable retaining element does not result in a preferred position. Thus, continuous displacement of the filling opening cover on the cover is possible with a simultaneous magnetic holding force.

Furthermore, it is advantageous if a locking element in the form of a magnetic holding element is arranged adjacent to at least one free end of the holding strip, which locking element interacts with the magnetic holding element on the filling opening cover in the closed position and/or the filling position to hold the filling opening cover in the closed position and/or the filling position in a defined manner. As already explained, two interacting magnetic holding elements can effect a locking action, since they exert a stronger magnetic force on one another in certain relative positions than the interaction of a magnetic element and a magnetizable element. For example, as already explained, the filling position and/or the closed position can each be predetermined by an additional magnetic holding element, which can be positioned adjacent to free ends of the holding strip. If these are arranged on the cover together with the holding strip, then a locking action can be realized in interaction with a magnetic element, for example a magnet, on the filling opening cover. For this purpose, the magnets are arranged so that the south pole of one magnet is aligned with the north pole of the other magnet in the respective locking position. To unlock, the magnetic holding force must then be overcome. The magnetic holding element is disengaged from the other magnetic holding element, and the magnetic force acting solely between the holding strip and the magnetic holding element holds the filling opening cover to the lid in all other positions between the closed position and the filling position.

A particularly compact design of the lid device can be achieved if at least one of the at least two retaining elements forms one of the first and second locking elements. As already explained, this allows for a magnetic locking of the filling opening lid and the lid relative to each other in the closed position or the filling position. Of course, optionally, i.e., alternatively or additionally, mechanical locking elements can also be provided on the lid and the filling opening lid, which interact in the closed position and/or the filling position.

According to a further preferred embodiment, the lid device can be provided with a guide device for guiding the movement of the filling opening lid from the closed position to the filling position and vice versa. Such a guide device makes it possible, in particular, to keep the filling opening lid in a defined relative position on the lid at all times. Furthermore, it facilitates handling for the user, since the movement of the filling opening lid is guided automatically.

The lid device can be designed in a simple manner if the guide device comprises cooperating first and second guide elements, which are arranged or formed on the one hand on the filling opening lid and on the other hand on the lid and are engaged in a guide position. In particular, the first and second guide elements can be positively engaged. In particular, however, they can be engaged without undercuts, which nevertheless enables positive engagement. An undercut-free design enables, in particular, easy lifting of the filling opening cover from the lid without the need to mechanically disengage guide elements.

The guide device can be easily configured if the interacting first and second guide elements are designed in the form of a guide projection and a corresponding groove-shaped guide receptacle, and if the guide projection engages in the guide receptacle in the guide position and guides a movement of the filling opening cover from the closed position to the filling position and vice versa. For example, the guide projection can be pin-shaped and engage in a corresponding guide groove formed by the guide receptacle. The guide groove can, in particular, be straight or curved, depending on the design of the cover device.

The lid device can be designed particularly simply and compactly if the guide projection is arranged or designed to protrude from an underside of the filling opening lid.

Preferably, the guide projection comprises the retaining element receptacle. This can then serve, on the one hand, to accommodate a magnetic retaining element and, on the other hand, to serve as a guide projection to guide movement of the filling opening cover relative to the cover.

Furthermore, it is advantageous if one of the at least two retaining elements is arranged or formed on the guide projection. This allows the user to visually determine the current position of the lid device. In particular, the retaining element can be held or arranged in the retaining element receptacle of the guide projection.

It is advantageous if at least one locking element cooperating with the guide projection is arranged or designed on the guide receptacle to lock the filling opening cover to the cover in the closed position and/or the filling position. This can be, as above, As explained, this could be a magnetic holding element. Alternatively, mechanically acting locking elements such as locking lugs arranged or formed on the guide receptacle are also conceivable, in order to hold or lock the guide projection in the guide position and/or the filling position in a defined manner.

The lid device can be designed in a simple manner if the at least one locking element is arranged or formed on a circumferential guide receptacle edge delimiting the guide receptacle. In particular, the at least one locking element can be designed in the form of a locking knob. A peg-shaped guide projection can interact with such a locking element. In particular, it can latch with it. In this way, a user can haptically specify a specific position of the filling opening cover on the lid. To move the filling opening cover relative to the lid from a locked position, the guide projection must then, for example, be moved past the locking element, for example past the locking knob, which requires increased force. Such unlocking or locking is then noticeable to the user.

To ensure secure locking of the filling opening cover to the lid in a locked position, it is advantageous if two mutually facing locking elements are arranged or configured on the guide receptacle to define the closed position and/or two mutually facing locking elements to define the filling position. These can, for example, interact with a guide projection of the guide device and specifically define a locking position.

Advantageously, the retaining strip extends parallel to the groove-shaped guide. This ensures, in particular, that the filling opening cover can be securely held on the cover in any position between the closed position and the filling position. For a compact design of the lid device, it can be advantageous if the first and second holding elements are assigned to the first and second guide elements. As already explained, for example, one of the magnetic holding elements can be arranged or formed on the guide projection of the guide device. A second holding element, for example in the form of a magnetizable holding strip, can be assigned to the other guide element. Thus, the first and second guide elements can, on the one hand, securely guide a movement of the filling opening cover on the lid, and, on the other hand, the first and second cooperating holding elements can reliably hold the filling opening cover on the lid.

In order to enable the filling opening cover and the cover to move relative to each other with as little force as possible, it is advantageous if the first and second guide elements are separated from each other by an air gap in the guide position.

Preferably, one of the guide elements forms a locking element of the locking device. As described, a guide projection of the guide device can form one of the locking elements of the locking device. It can, in particular, interact with locking knobs on the guide receptacle to hold the filling opening cover in a defined manner either in the filling position or in the closed position.

The object stated at the outset is further achieved according to the invention in a table water jug of the type described at the outset in that the container lid is designed in the form of one of the advantageous embodiments of lid devices described above.

Developing a table water jug in this way offers, in particular, the advantages already described above in connection with preferred embodiments of lid devices. Such a table water jug is easy and reliable to handle. Furthermore, it is advantageous if the table water jug comprises a lid coupling device for force-fitting and/or positive-locking coupling of the jug container and the lid device in the closed position. Such a lid coupling device makes it possible, in particular, to reliably fix the container lid to the jug container.

The table water jug is easy to handle if the lid coupling device is designed as a first locking or snap-in connection. For example, the user can intuitively place the container lid onto the jug container and snap it into place.

The table water jug can be easily configured if the lid coupling device comprises cooperating first and second lid coupling elements, which are arranged or formed on the one hand on the jug container and on the other hand on the container lid, and if the first and second lid coupling elements engage in a force-locking and/or positive-locking manner in the closed position. The container lid can thus be reliably coupled to the jug container in the closed position.

The lid coupling device can be implemented in a simple manner if the first and second lid coupling elements are designed in the form of at least one lid coupling element projection and at least one corresponding lid coupling element recess. These can engage in a force-locking and/or positive-locking manner, particularly in the closed position.

Advantageously, the first and second lid coupling elements are designed in the form of first locking and/or snap-on connection elements. For example, they can be designed in the form of locking projections and corresponding locking recesses that engage in a force-locking and/or positive-locking manner in the closed position. To handle the table water jug, it is advisable to hold the jug handle with one hand.

Preferably, the handle is located or formed on the side of the jug body. This allows the user to safely grasp and handle the water jug, for example, when filling or pouring water from the jug.

It is advantageous if the table water jug has a spout for the targeted pouring of water collected in the table water jug.

Conveniently, the spout is located on the side of the jug container. This allows the spout to remain open even when the water jug is closed with the container lid.

It is advantageous if the handle and spout are arranged or designed to point in opposite directions on the jug body. This simplifies handling of the table water jug, especially when pouring the water it contains.

Preferably, the container lid releases the spout when in the closed position. In other words, even if the container lid completely closes the jug's container opening, water can be drawn from the tabletop water jug by pouring it from the spout.

The tabletop water jug is preferably designed as a tabletop water filter jug for filtering water. Such a tabletop water jug can therefore serve a dual function. On the one hand, it can be used to provide water for filling drinking containers. On the other hand, it can be used to filter tap water or otherwise treat it before consumption. According to a further preferred embodiment, it can be provided that the jug container comprises a jug insert, that the jug insert is received in the jug container in an insert position and that the container lid closes the jug insert in the closed position. In this way, it is not possible to have unrestricted access to the jug insert in the closed position. If the container lid is designed in particular in the form of a lid device, as described above in numerous preferred embodiments, access to the jug insert can, however, be enabled by the filling opening being uncovered using the filling opening lid. This then makes it possible to fill water into the jug insert through the filling opening.

When in use, the jug insert preferably borders on the spout and exposes the latter. In particular, the jug insert can be designed such that it divides the jug container into two areas, namely a first area defined by the jug insert and a further area defined by the jug insert relative to the jug container. In this way, unfiltered water can be poured into the jug insert and then flow through a filter insert arranged in the jug insert, for example, to reach the jug container, i.e. into an area thereof outside the jug insert. In this way, the jug insert separates untreated and treated water in the jug container. However, the area of the table water jug for treated water is accessible via the spout, so that treated water can be poured from the table water jug.

It is advantageous if the jug container includes an insert coupling device for force-fitting and/or positive-locking coupling of the jug container and the jug insert in the use position. Such an insert coupling device improves the stability of the table water jug. The jug insert can thus be arranged in the jug container in a defined manner and held mechanically securely. The table water jug can be handled easily if the insert coupling device is designed in the form of a second locking or snap-in connection device.

It is advantageous if the insert coupling device comprises cooperating first and second insert coupling elements, which are arranged or formed on the one hand on the can container and on the other hand on the can insert, and if the first and second insert coupling elements engage in a force-locking and/or positive-locking manner in the insert position. This allows a user to easily connect the can insert and the can container to one another in the insert position.

For intuitive handling of the table water jug, it is advantageous if the first and second insert coupling elements are designed in the form of second locking or snap-in connection elements. Here, too, cooperating locking projections and locking recesses can be provided, which engage in a force-locking and/or positive-locking manner in the inserted position.

According to a further preferred embodiment, the first or second lid coupling elements of the lid coupling device can be arranged or formed on the can assembly. This makes it possible, in particular, to couple the container lid to the can insert in the closed position. If the can insert is coupled to the can container by means of the insert coupling device, the container lid is also coupled to the can container, indirectly via the can insert.

It is advantageous if the jug insert can be removed from the jug container in the closed position. This means, in particular, that the container lid can be coupled to the jug insert when the jug insert is removed from the jug container. According to a further preferred embodiment, the table water jug can be provided with a filter insert for insertion into the jug container. The filter insert can be designed, in particular, to filter and/or demineralize water, especially tap water. For example, the filter insert can be used to decalcify the water contained in the table water jug.

It is advantageous if the filter insert comprises a housing with a housing opening and a housing cover for closing the housing opening in a filtering position, and if the housing forms a housing receptacle for accommodating a filter element. Such a filter insert makes it possible, in particular, to replace the filter element when it is used or exhausted. The housing and housing cover can then be reused. To replace the filter element, simply remove the housing cover from the housing and replace the used filter element with a new one.

For reliable handling of the table water jug, it is advantageous if the filter insert comprises a housing lid guide device for guiding the movement of the housing lid relative to the housing when transferring the filter insert from the insertion position, in which the housing lid is completely separated from the housing, into the filter position. In the insertion position, a used filter element can be removed from the housing receptacle and replaced with an unused filter element. The housing lid guide device enables the user, in particular, to easily and securely close the housing with the housing lid.

It is advantageous if the housing cover guide device comprises a slotted guide for guiding a movement of the housing cover relative to the housing along a guide track. Such a slotted guide automatically indicates to the user how the housing cover is to be moved relative to the housing. This can be particularly advantageous if the housing cover on the housing in the filter position. The guide rail can thus move or guide the housing cover to the locking position in a defined manner.

It is advantageous if the guideway is straight or curved. In particular, it can be L-shaped or U-shaped. This allows the relative movements of the housing cover and housing during engagement and locking to be separated, particularly with L-shaped or U-shaped guideways. Different directions can therefore be specified for these movements.

In order to ensure a reliable connection of the housing cover to the housing and also a corresponding guidance of the same relative to each other, it is advantageous if the slotted guide comprises at least two, in particular four, guide grooves and if the guide grooves define the guide path.

It is advantageous if the guide rail comprises at least two, particularly four, guide elements that interact with and engage in the guide grooves. This ensures a stable connection and guidance of the housing cover and housing relative to each other.

It is advantageous if each guide element engages the associated guide track in the filter position. This allows the user to feel when the housing cover on the housing assumes the desired filter position, i.e., when the housing receptacle is securely and precisely closed. This provides the user with tactile feedback when handling the filter insert.

Figures 1 to 27 schematically show an embodiment of a table water jug, designated overall by the reference numeral 10.

The table water jug 10 is designed as a table water filter jug 12 for treating, in particular for filtering, water. The table water jug 10 comprises a jug container 14, a jug insert 16, a lid device 18 and a filter insert 20. The above-mentioned components are described in detail below, in particular their interaction.

The jug container 14 has an elongated oval shape, as clearly visible in the top view in Figures 7 and 8. A circumferential edge protrudes from a bottom 22, forming a base. A circumferential wall 28 protrudes from the bottom 22, which, when the table water jug is used as intended, extends against the direction of gravity, symbolized by arrow 26 in Figure 2. The wall 28 extends to an upper edge 30 of the jug container 14.

A spout 32 is formed on the jug container 14, specifically by a lateral bulge 34 of the wall 28 on a semi-hollow-cylindrical wall section 36. The wall section 36 connects two parallel, flat wall sections 38 and 40. Opposite the wall section 36, along a center line 42 extending between the wall sections 36 and 38, which moreover runs in a plane of symmetry of the table water jug 10, another semi-hollow-cylindrical wall section 44 is formed, which also connects the wall sections 38 and 40.

The table water jug 10 comprises a jug handle 46, which is arranged on the wall section 44. It comprises two curved sections that are integrally formed on the wall section 44 and connected to one another via a handle section 48 running parallel to the wall section 28. Overall, a substantially U-shaped jug handle 46 is thus formed. The jug handle 46 serves to hold the table water jug 10 with one hand. As described, it is arranged or formed laterally on the jug container 14. The spout 32 and jug handle 46 elements, formed on the one hand on the wall section 36 and on the other hand on the wall section 44, point in opposite directions and each away from the jug container 14. The spout 32 formed on the side of the jug container 14 extends to the upper edge 30. In Figure 3 it can be clearly seen that the spout 32 forms a bulge 34 on the edge 30.

The can container 14 defines a can container opening 50 in the region of the upper edge 30. The lid device 18 forming a container lid 52 serves to close the opening. In this exemplary embodiment, the container lid 42 is not coupled directly to the can container 14, but indirectly via the can insert 16. A lid coupling device 54 serves to couple the container lid 52 to the can container 14. It is designed for the force-fitting and/or form-fitting coupling of the lid device 18 to the can container 14, specifically indirectly via the can insert 16.

The lid coupling device 54 is designed in the form of a first locking or snap-in connection device 56. The lid coupling device 54 comprises cooperating first and second lid coupling elements 58 and 60, which are arranged or formed on the one hand on the can insert 16 and thus indirectly on the can container 14, and on the other hand on the container lid 52.

In a closed position, in which the container lid 52 closes the can container opening 50, the first and second lid coupling elements 58, 60 are engaged in a force-locking and/or positive-locking manner, as can be clearly seen in Figure 12. Figure 1 also shows the closed position.

The first and second lid coupling elements 58 and 60 are designed in the form of a lid coupling element projection 62 on the container lid 52 and a lid coupling element recess 64 corresponding thereto. The first and second lid coupling elements 58 and 60 are designed as first and second locking or snap-in connection elements. The first lid coupling element forms a first locking element 66 in the form of a locking recess, and the second lid coupling element 60 forms a first locking or snap-in connection element in the form of a locking lug that engages the locking recess in the closed position. This can be clearly seen in Figure 12.

The first lid coupling elements 58 are formed on the jug insert 16 in the form of recesses that open toward one another. They are formed adjacent to the spout 32 on the one hand and adjacent to the jug handle 46 on the other. Thus, two first lid coupling elements 58 are formed on the jug insert 16, and two second lid coupling elements 60 are formed on the container lid 52.

As shown in Figure 4, the can insert 16 is received in the can container 14 in an inserted position. In the closed position, the container lid 52 closes the can insert 16, as can be clearly seen in Figure 2. In the closed position, the container lid 52 exposes the spout 32. As can be clearly seen in Figure 4, the can insert 16 also exposes the spout 32 in the inserted position. However, it borders on the spout, which is also clearly visible in the sectional view of Figure 2.

The table water jug 10 further comprises an insert coupling device 70 for force-fitting and/or positive-locking coupling of the jug container 14 and the jug insert 16 in the insert position. The insert coupling device 70 is designed in the form of a second locking or snap-in connection device 72.

The insert coupling device 70 comprises first insert coupling elements

74 and second insert coupling elements 76, which are arranged on the one hand on the can container 14 and on the other hand on the can insert 16 or are formed. In the inserted position, the first and second insert coupling elements 74 and 76 are engaged in a force-fitting and/or form-fitting manner. The first and second insert coupling elements 74 and 76 are designed in the form of second locking or snap-in connection elements 78 and 80, respectively. They are engaged in the inserted position, as can be clearly seen in Figures 5 and 6.

The insert coupling device 70 comprises a total of four first insert coupling elements 74 and four corresponding second insert coupling elements 76. The four first insert coupling elements 74 are arranged or formed in the transition region between the wall sections 36 and 38 or 40 and 44, respectively, in the form of depressions which are formed slightly below the edge 30 in an inner wall surface 82 of the wall 28.

The second insert coupling elements 76 are designed as short ribs 84 that extend parallel to an upper edge 86 of the jug insert 16. The edge 86 is circumferential and, viewed from above, has an elongated oval shape. It fits snugly against the wall 28 in the region of the edge 30, but does not follow the bulge 34. Thus, the spout 32 remains free.

As clearly shown in Figure 3, the can insert 16 can be removed from the can container 14 in the closed position, i.e., with the container lid 52 coupled to the can insert 16. Therefore, the container lid 52 does not need to be removed from the can insert 16. Conversely, the can insert 16 can also be inserted into the can container 14 with the container lid 52 in place.

Slightly set back from the edge 86, the can insert 16 tapers towards the underside 22, as can be clearly seen in Figure 2, when the can insert 16 is accommodated in the can container 14 as intended. The further design of the jug insert 16 will be explained in more detail later in connection with the description of the filter insert 20.

The design of the cover device 18 will now be explained in more detail.

The lid device 18 comprises a lid 88 with a filling opening 90. It serves, in particular, the purpose of filling the can container 14 with the lid device 18 in place. To close the filling opening, the lid device 18 comprises a filling opening cover 92. The filling opening cover 92 can be moved from a closed position, in which it closes the filling opening 90, for example, as shown in Figure 8, into a filling position, in which it at least partially exposes the filling opening 90. The filling position is shown schematically in Figure 7.

The lid device 18 further comprises a lid holding device 94. It is free of undercuts and designed to hold the filling opening cover 92 on the cover 88 purely by force. This design makes it possible to move the filling opening cover 92 from a holding position, in which the filling opening cover 92 is held on the cover 88, as shown schematically in Figure 10, into a separating position, in which the filling opening cover 92 is removed and separated from the cover 88. Figure 9 shows such a situation. The exploded view of Figure 9, particularly in the area of the filling opening cover 92, shows the coupling to the cover 88 without an undercut.

The filling opening cover 92 is designed to slide on the cover 88 when transferred from the closed position to the filling position and vice versa. For this purpose, the cover device 18 comprises a plurality of sliding elements 96. They are designed in the form of sliding projections 98. In the embodiment of Figures 1 to 27, the sliding elements 96 are arranged or formed on the filling opening cover 92. The sliding projections 98 are knob-like and protrude from an underside 100 of the filling opening cover. A total of four sliding elements 96 are formed on the filling opening cover 92 and are positioned near a circumferential edge 102. A sliding surface 104, which is arranged or formed on the cover 88, interacts with the sliding elements 96. The sliding surface 104 is flat and laterally delimits the filling opening 90 in sections. The sliding elements 96 rest against the sliding surface 104 when the filling opening cover 92 is moved from the closed position to the filling position and vice versa. This can be seen particularly clearly in Figures 13 and 14. Figure 13 shows the filling position, Figure 14 the closed position.

The lid device 18 comprises a locking device 106 for locking the filling opening lid 92 in at least one locking position. In the exemplary embodiment illustrated in Figures 1 to 27, the filling opening lid 92 is locked in both the closed position and the filling position, as will be explained in more detail below. Thus, both the closed position and the filling position each define a locking position. In alternative exemplary embodiments, it is also conceivable to lock either only the closed position or only the filling position.

The locking device 106 comprises cooperating first and second locking elements 108 and 110, which are arranged or formed on the one hand on the cover 88 and on the other hand on the filling opening cover 92. The cooperating first and second locking elements 108 and 110 are engaged in a force-locking and/or positive-locking manner in at least one locking position.

In Figures 7 and 8 it can be clearly seen that the first and second locking elements 108 and 110 form cooperating locking projections 112 and locking receptacles 114. Two locking elements in each case Elements 108 are arranged in pairs opposite one another on an elongated guide receptacle, specifically on a circumferential guide receptacle edge 118 delimiting the latter.

The guide receptacle 116 is groove-shaped on the lid 88 and, relative to the sliding surface 104, is set back toward an interior space 120 of the can container 14. The first locking elements 108 are in the form of locking knobs 122. They are arranged adjacent to a free end 124 of the guide receptacle 116 in such a way that the second locking element 110, which is in the form of a locking projection 112 projecting from the filling opening lid 92 beyond the underside 100, can engage.

The free end 124 is formed adjacent to the filling opening 90; opposite it, another free end 126 of the guide receptacle 116 is delimited by the guide receptacle edge 118. Two locking studs 122 are also positioned adjacent here. The locking studs 122, each of which interacts with one of the two ends 124 and 126, are positioned such that the locking projection 112 can engage or snap into the locking receptacles 114 delimited by the locking studs 122 and the ends 124 and 126, respectively.

Figure 7 shows the locking projection 112 in cooperation with the end 126. The locked locking projection 112 thus defines the filling position of the lid device 18. The locking projection 112 locked between the two locking knobs 122 and the end 124 defines the closed position of the lid device 18.

A circumferential inner edge surface 128 is formed on the cover 88. The edge surface 128 defines stops 130 and 132 acting in opposite directions for the filling opening cover 92. In the closed position, the filling opening cover 92 rests against the stop 130 adjacent to the filling opening 90. In the filling position, the edge 102 of the filling opening cover 92 rests against the stop 132.

The edge surface 128 extends transversely, in the embodiment shown in the figures vertically, away from the sliding surface 104.

A contour of the edge surface 128 corresponds to an outer contour, thus the edge 102, of the filling opening cover 92 such that the filling opening cover 92 and the edge surface 128 lie flat against each other, or essentially flat, both in the filling position and in the closed position. This is particularly clearly visible in Figures 7 and 8, as well as 13 and 14.

In the embodiment illustrated in the figures, the lid holding device 94 comprises a magnetic holding device 134 for magnetically holding the filling opening lid 92 on the lid 88 in the holding position by means of magnetic force. In the present embodiment, the filling opening lid 92 is held on the lid 88 exclusively by means of magnetic force.

The magnetic holding device 134 comprises two cooperating holding elements 136 and 138. The holding element 136 is arranged or formed on the filling opening cover 92 and the holding element 138 on the cover 88.

The holding element 136 is magnetic. It is designed in the form of a magnet 140. The magnetic holding element 136 is rotationally symmetrical with respect to a holding element longitudinal axis 142. It comprises a holding flange 144 projecting radially relative to the holding element longitudinal axis 142. The holding element 136 is held in a holding element receptacle 146. The holding element receptacle 146 is formed in the form of a recess on the locking projection 112. The holding element receptacle 146 is rotationally symmetrical with respect to the holding element longitudinal axis 142. It comprises an annular surface 148 facing away from the underside 100, against which the holding flange 144 rests. In order to hold the holding element 136 in the holding element receptacle 146, the holding device 134 comprises a holding member 150. It is sleeve-shaped and has a retaining flange 152 projecting in the radial direction relative to the holding element longitudinal axis 142. Detent lugs 154 protrude from a sleeve-shaped outer side and engage in detent recesses 156 on the holding element receptacle 146. An end face 158 at the end of the holding member 150 facing away from the retaining flange 152 bears against the holding flange 144.

To mount the magnet 140 on the filling opening cover 92, proceed as schematically shown in Figures 16 and 17. The magnet 140 is inserted with the retaining flange 144 first into the retaining element receptacle 146 parallel to the retaining element longitudinal axis 142. To fix the magnet 140, in the next step, the retaining member 150 is inserted into the retaining element receptacle 146 with the end face first, which is interrupted in the circumferential direction relative to the retaining element longitudinal axis 142 and is therefore only formed at individual spring tabs 160, surrounding the magnet 140, until the end face 158 abuts the retaining flange 144. The locking lugs 154 slide into the locking recesses 156 and thus establish a locking connection between the retaining member 150 and the retaining element receptacle 146.

The holding member 150 serves to hold the holding element 136 in the holding element receptacle 146 in a force-fitting and/or form-fitting manner. As described, the holding member 150 and the holding element receptacle 146 are connected to one another in a locking manner when they hold the holding element 136 in the holding element receptacle 146. The filling opening cover 92 is designed to be mirror-symmetrical with respect to a mirror plane 162 containing the holding element longitudinal axis.

For handling the filling opening cover 92, a rib 164 extending in the mirror plane 162 is formed on an upper side of the filling opening cover 92.

In the embodiment illustrated in the figures, the second holding element 138 is designed to be magnetizable. It is formed at least partially from a magnetizable material. This is a metallic material containing iron, cobalt, and/or nickel.

The magnetizable holding element 138 is designed in the form of a holding strip 166. A holder 168 for the holding strip 166 is formed on an underside of the cover 88. It comprises two laterally open grooves 170 facing one another, into which the holding strip 166 can be inserted parallel to the groove-shaped guide receptacle 116.

To protect the retaining strip 166, which is made of a non-corrosive material, from corrosion, a hood 172 forms a retaining element receptacle 174. Once the retaining strip 166 has been inserted into the holder 168, the hood 172 can be pushed over the holder 168 in a next assembly step. To support the retaining strip 166 along its extension, two guide webs 176, each with a recess 178, are arranged on an inner side of the hood 172, into which the retaining strip 166 engages when the hood 172 is placed on the holder 168. In this regard, particular reference is made to Figures 13, 14, and 19.

The retaining strip 166 extends in a displacement direction 180. This is defined in particular by a longitudinal axis of the guide receptacle 116. The retaining strip 166 thus extends in the displacement direction 180 of the filling lid 92. In the exemplary embodiment described in the figures, the retaining strip 166 has a length such that it interacts with the magnet 140 in any position of the filling opening cover 92 relative to the cover 88, i.e., both in the filling position and in the closed position, and in any other position between these two extreme positions. Thus, whenever the filling opening cover 92 is placed on the cover 88 as intended, the retaining element 136 magnetically interacts with the retaining strip 166. The retaining strip 166 is attracted by the magnet 140. Since the magnet 140 is held on the filling opening cover 92, the filling opening cover 92 is pulled against the cover 88.

The hood 142 is welded to the cover 88, ensuring that the retaining element receptacle 174 is sealed fluid-tight. The retaining strip 166 is thus protected against corrosion.

The lid device 18 further comprises a guide device 182 for guiding a movement of the filling opening lid 82 from the closed position to the filling position and vice versa. The guide device 182 comprises cooperating first and second guide elements 184 and 186. The first and second guide elements 184 and 186 are arranged or formed on the one hand on the filling opening lid 92 and on the other hand on the lid 88. In a guide position, they are engaged, in particular in a form-fitting manner. It is particularly noteworthy that the cooperating first and second guide elements 184 and 186 engage without undercuts.

The first and second guide elements 184 and 186 are designed in the form of a guide projection 188 and the guide receptacle 116 corresponding thereto. The guide projection 188, which thus also forms the locking projection 112, engages in the guide receptacle 116 in the guide position and guides a movement of the filling opening cover 92 from the closed position to the filling position and vice versa. As already explained, the guide projection 188 protrudes from the underside 100 of the filling opening cover 92. In this embodiment, the guide projection 188 encompasses the holding element receptacle 146.

As explained, the holding element 136 in the form of the magnet 140 is arranged or formed on the guide projection 188. At least one locking element 108 cooperating with the guide projection 188 is arranged or formed on the guide receptacle 116 for locking the filling opening cover 92 to the cover 88 in the manner described in the closed position and in the filling position. The locking elements 108 are arranged or formed on the circumferential guide receptacle edge 118 delimiting the guide receptacle 116, specifically in the form of locking knobs 122.

The holding strip 166 extends parallel to the groove-shaped guide receptacle 116. Thus, in this embodiment, the first and second holding elements 136 and 138 are assigned to the first and second guide elements 184 and 186.

The first and second guide elements 184 and 186 are separated from each other in the guide position by a narrow air gap 190. The interacting guide elements 184 and 186 are virtually contact-free and thus enable a virtually frictionless guidance of the movement of the cover 88 and the filling opening cover relative to each other.

As already explained, one of the two guide elements 184 and 186, namely the guide element 184, also forms the second locking element 110 of the locking device 106.

Adjacent to the hood 172, a change indicator 192 is arranged on the underside of the cover 88. The change indicator 192 comprises a rotatable wheel 194, which is divided into twelve equal sectors, which are labeled with numbers from 1 to 12 are labeled. A marking 196 in the form of a short groove is formed on the hood 172, extending in the direction of the displacement direction 180. When the filter insert 20 is replaced, the respective month can be set on the replacement indicator 192 by aligning the number corresponding to the month with the marking 196. This allows a user to immediately see when the filter insert 20 was last replaced.

The can insert 16 and the filter insert 20 are described in more detail below. As already explained, the can insert 16 can be inserted into the can container 14 in a defined manner. Figure 2 schematically shows that the can insert 16 is designed to accommodate the filter insert 20 in the inserted position.

The can insert 16, coupled to the can container 14 by means of the insert coupling device 70, has a circumferential can insert wall 198, which extends in a funnel shape from the edge 86 to a can insert base 200. When the can insert 16 is received in the can container 14, the can insert base 100 is spaced from the underside 22 of the can container 10. A distance 202 of the can insert base 200 from the underside 22 is approximately one-third of the total height of the can container 14, which is predetermined by a distance between the edges 24 and 30.

The can insert 16 tapers geometrically similarly to the shape of the rim 86, so that any cuts through the can insert 16 parallel to a plane defined by the rim 86 are each elongated oval-shaped.

A can insert base opening 204 is formed on the can insert base 200, which is also elongated oval-shaped. On an inner wall surface 206 of the jug insert 16, several guide ribs 208 are arranged or formed, extending from the jug insert base 200. They serve, in particular, to center the filter insert 20 when inserting it into the jug insert 16.

In the exemplary embodiment of the can insert 16 illustrated in the figures, a total of six guide ribs 208 are provided. They each extend into a can insert space 210 defined by the can insert 16 and protrude transversely, in particular perpendicularly, from the inner wall surface 206. The guide ribs 208 are flat and have a sliding surface 212 extending into the can insert space 210. This sliding surface serves to guide the filter insert 20 into a filter insert position, as illustrated by way of example in Figures 2 and 25, when inserted into the can insert 16.

The sliding surface 212 is partially rectilinear and partially convexly curved toward the can insert space 210. Figure 25 shows a rectilinear section 214 and a curved section 216. The rectilinear section 214 extends from the can insert base 200 toward the edge 30. It then transitions into the convexly curved section 126, which points toward the can insert space 210 and ends at the inner wall surface 206.

The guide ribs 208 are designed in such a way that when the filter insert 20 is received in the jug insert 16, they lie flat against the outside of the latter.

The filter insert 20 comprises a trough-shaped housing 218 with a housing opening 220 and a housing cover 222 for closing the housing opening 220 in a filtering position. The housing 218 forms a housing receptacle 224 for receiving a filter element 226.

The filter element 226 comprises a flexible, fluid-permeable filter bag 228 in which a filter material 230 is accommodated. The filter material 230 can optionally be designed to filter out suspended matter and/or to demineralize, in particular to decalcify, water. For example, the filter material 230 can comprise a plurality of beads made of an ion-exchange material.

The housing 218 defines a housing top 232, on which the housing opening 220 is also formed, and a housing bottom 234. The housing 218 tapers from the housing top 232 to the housing bottom 234, similar to the can insert 16.

Two water outlets 236 are formed on the housing 218, specifically on the housing bottom 234. The two water outlets 236 are circular and each closed by a mesh filter 238. The mesh filter 238 is, of course, designed to be fluid-permeable.

A housing base 240 protrudes from the housing bottom 234. The water outlets 236 are formed on the housing base 240, as can be clearly seen in Figures 25 and 26, for example. Several support webs 242 for the filter element 226 are formed on the housing bottom 234. They protrude from the housing base 240 toward the housing receptacle 224. They serve the particular purpose of keeping the filter element 226 spaced apart from the water outlets 236 and the mesh filters 238.

In the exemplary embodiments illustrated in the figures, three support webs 242 are provided. They extend transversely, namely perpendicularly, to a preferred housing axis 244. This axis is defined in particular as parallel to two rectilinear and mutually parallel housing opening edge sections 246 of a housing opening edge 248 delimiting the housing opening 220.

The housing base 240 of the filter insert 20 is immersed in the can insert base opening 204 when the filter insert 20 is received in the can insert 16. This immersion is easily achieved by the guide ribs 208 with their Sliding surfaces are provided which interact with the housing 218 of the filter insert and guide it in such a way that the housing base 240 is guided into the can insert base opening. The guide ribs 208 then lie flat against the outside of the housing 218, as can be clearly seen in Figures 2 and 25.

The filter insert 20 comprises a housing cover guide device 250 for the defined engagement and closure of the housing 218 with the housing cover 222. It serves to guide a movement of the housing cover 220 relative to the housing when transferring the filter insert 20 from an insertion position, in which the housing cover 222 is completely separated from the housing 218, into the filter position, in which the housing cover 222 closes the housing opening 220 of the housing 218. The insertion position is shown schematically in Figure 26.

The housing cover guide device 250 comprises a slotted guide 252 for guiding a movement of the housing cover 222 relative to the housing 218 along a guide track 254. In the embodiment illustrated in the figures, the guide track 254 is L-shaped. Thus, it is curved. Alternatively, the guide track 254 can also be linear or U-shaped.

The slotted guide 252 comprises at least two guide grooves 256, four in the embodiment shown in the figures. Two of the four guide grooves are identical. The guide grooves 256 define the guide track 254.

The guide grooves 256 extend into a housing wall 258 of the housing 218 as recesses that are open toward the housing receptacle 224. They interrupt the housing opening edge 248 at an open end 260. A circumferential edge flange 262 extends from the housing opening edge 248 away from the housing opening 220. This edge flange 262 is also interrupted by the open ends 260 of the guide grooves 256. The edge flange 262 defines an edge support surface 264. It extends outwardly from the housing opening edge 248.

A circumferential can insert support edge 266 extends from the edge support surface 264. It points away from the housing receptacle 224. In the inserted position, in which the filter insert 20 is inserted into the can insert 16, the can insert support edge 266 rests flat against the circumferential can insert wall 198, which tapers from the can container opening 50 toward a container bottom 268 of the can container 14. The can insert wall 198 defines the wall surface 206 delimiting the can insert space 210.

The can insert support edge 266 is inclined by an angle of inclination 274 relative to a can insert longitudinal axis 270. In the embodiment illustrated in the figures, the angle of inclination 274 is in a range from approximately 3° to approximately 12°.

The can insert contact edge 266 serves in particular to seal the filter insert 20 relative to the can insert 16. The can insert wall 198, like the can insert contact edge 266, is inclined by the angle of inclination 274 relative to the can insert longitudinal axis 272. In the filter insert position, as shown in Figure 2, the can insert contact edge 266 thus divides the can insert space 210 into a region above the can insert contact edge 266 and a region below the can insert contact edge 266. The guide ribs 208 are arranged or formed in the region below the can insert contact edge 266.

The housing opening edge 248 further comprises two convexly curved housing opening edge sections 276 and 278 pointing away from the housing opening 220. which connect the two rectilinear housing opening edge sections 246 with each other.

The can insert support edge 266 does not have a constant width across its circumference. It is formed with a constant width in the region of the rectilinear housing opening edge sections 246 and in the region of the curved housing opening edge section 276. This results in the edge support surface 264, which borders the housing opening edge section 276, widening starting from the area adjacent to the rectilinear housing opening edge sections 246. Opposite, however, the widening can insert support edge 266 in the region of the convexly curved housing opening edge section 278 results in the edge support surface 264 having a constant width, which corresponds to a width of the edge support surface 264 in the region of the rectilinear housing opening edge sections 246.

This configuration also has an effect on the configuration of the guide track 254. It comprises a first track section 280 extending transversely, almost vertically, from the edge support surface 264 in the region of the rectilinear housing opening edge sections 246 and an adjoining second track section 282 which runs substantially parallel to the edge support surface 264 and points in the direction of the housing opening edge section 278.

The design of the guide grooves 256 for forming the guide tracks 254, as well as the design of the can insert contact edge 266 and the adjacent edge support surface 264, results in a symmetry break in the filter insert 20. This means that the filter insert is only symmetrical to itself with respect to a single symmetry plane 284 containing the housing preferred axis 244. However, in a plane 286 perpendicular to this plane, the filter insert 20 as a whole is not mirror-symmetrical to itself. Guide members 288 are arranged or formed on the housing cover 222, encompassed by the slotted guide 252, interacting with and engaging in the guide grooves 256. Each of the four guide members 288 is arranged on a spring element 290, which deforms slightly toward the housing receptacle 224 when the guide members 288, aligned in pairs facing away from each other, are inserted into the guide track 254 provided for them.

On each guide groove 256, a locking recess 292 is provided, which extends slightly into a housing wall 294. This enables each guide member 288 to lock with the associated guide track 254 in the filter position, in which the housing cover 222 closes the housing opening 220 in a defined manner. For this purpose, one of the locking recesses 292 is formed on each guide track 254 or guide groove 256, into which the associated guide member 288 locks or snaps upon reaching the filter position. This occurs because, upon locking with the locking recess 292, the spring element 290 springs back into the basic position in the direction away from the housing receptacle 224.

The filter insert 20 thus comprises a housing cover locking device 296 for locking the housing cover 222 to the housing 218 in the filtering position. The housing cover locking device 296 comprises the guide members 288 and the correspondingly formed locking recesses 292 on the guide grooves 256.

On the housing cover 222, which is designed to be completely separable from the housing 218, several slot-like water inlets 298 are formed. They form openings in the housing cover 222. They allow water to flow from the jug insert space 210 above the filter insert 20 into the housing receptacle 224. The housing cover 222 is designed in the form of a shallow trough and has a cover base 300 which is interrupted, thus forming an opening 302. A handle element 304 with a U-shaped cross section is formed offset from the cover base 300 in the region of the opening 302. Thus, on both sides of the handle element 304 on the housing cover 222, two recessed grips 306 are formed, opening away from the housing receptacle 224. A user can thus engage with their thumb and middle finger in one of the two recessed grips 306 and grasp the housing cover 222 by the handle element 304. The handle element 304 extends transversely to the housing's preferred axis 244.

The water inlets 298 are formed both in the area of the two grip recesses 306 and on the handle element 304. Furthermore, the opening 302 also forms a water inlet 298.

The housing cover 222 comprises an outer circumferential cover edge 308, which defines a cover edge surface 310 pointing toward the housing receptacle 224. The circumferential cover edge 308 is connected to the two grip recesses 306 and the grip element 304 via an inclined circumferential annular wall 312. The housing cover 222 and the housing 218 are coordinated with one another such that, in the filter position, the cover edge surface 310 rests on the edge support surface 264. The link guide 252 is further configured such that, when the housing cover 222 is moved relative to the housing 218, the edge support surface 264 and the cover edge surface 310 remain aligned parallel to one another. As described, the housing cover 222 rests on the edge support surface 264 in the filter position.

The guide grooves 256 of the slotted guide 252 are further arranged and designed such that the housing cover 222 touches the housing 218 when the guide members 288 and the guide grooves 256 come into contact in the region of the curved housing opening edge section 276 and up to the Can insert contact edge 266 reaches this area. Through the predetermined first track section 280, the housing cover 222 is initially moved in the direction of the housing receptacle 224 until the cover edge surface 310 rests on the edge support surface 264. The guide members 288 are now located in the transition area between the first and second track sections 280 and 282.

The housing lid 222 can now be moved parallel to the housing preferred axis 244 in the direction of the curved housing opening edge section 278 until the lid edge 308 abuts the can insert contact edge 266 and then the lid edge surface 310 also touches the edge support surface 264 in the region of the curved housing opening edge section 278. During this movement, the guide members 288 and the locking recesses 292 then engage, as already described.

Due to the asymmetrical design of the housing 218 with respect to the plane 286, the edge support surface 264 of the housing opening edge 248 is at least partially visible in the filter position in the region of the curved housing opening edge section 276, which touches the housing cover 222 when the guide members 288 and the guide grooves 256 come into contact. A directional arrow 314 is arranged in this visible region of the edge support surface 264, which is visible in the filter position and indicates a direction of displacement of the housing cover 222 relative to the housing 218 for transferring the filter insert 20 from the filter position to the insertion position.

The housing preferred axis 244 is also defined by the housing opening 220. As described, the housing cover 222 resting on the edge support surface 264 is displaceable parallel or substantially parallel to the housing preferred axis 244, specifically from the insertion position to the filter position. The housing cover 222 is symmetrical with respect to both the plane of symmetry 84 and the plane 286.

The functionality of the table filter jug is briefly explained below.

As already mentioned, the table water jug 10 is designed as a table water filter jug 12. For use, it must be prepared as schematically shown in Figures 1 and 2. The jug insert 16 is inserted into the provided jug container 14 as described above. The filter insert 20 can then be inserted into the jug insert 16. The jug insert 16 is closed with the lid device 18.

The table water filter jug 12 can be filled with water with the container lid 52 in place. To do this, the filling opening lid 92 is moved into the filling position. In the filling position, it is held by the locking device 106 so that it cannot automatically move into the closed position. Untreated water, for example directly from a faucet, can now be poured into the jug insert 16 through the filling opening 90. The added untreated water flows through the water inlets 298 on the housing cover 222 of the filter insert 20 into the latter and flows through the filter element 226. After flowing through the filter element 226, the now treated water exits the jug insert 16 through one of the water outlets 236 and flows into the jug container 14. There it collects and can be poured out of the jug container 14 through the spout 32.

Once the filter element 226 is used up, the container lid 52 is removed from the can insert 16 and the filter insert 20 is removed by a user grasping the handle element 304 and thus lifting the filter insert 20 out. To open the housing 218, the housing lid 222 is moved in the direction of the arrow 314 from the filter position to the insertion position. In the insertion position, the housing lid 222 covers the Area of the edge support surface 264 with the directional arrow 314. The guide members 288 are now each in a position in the transition area between the first and second track sections 280, 282. The housing cover 222 can now be lifted from the housing 218 by a movement in the direction of the first track section 280. The filter element 226 can now be removed from the housing receptacle 224 and replaced with a new, unused filter element 226.

To close the housing 218, proceed in reverse order. The filter insert 20 can then be reinserted into the jug insert 16. The guide ribs 208 ensure that the housing base 240 of the filter insert 20 is guided into the desired position, namely, that it can be inserted into the jug insert base opening 204 without jamming. Finally, the container lid 52 only needs to be placed on the jug insert 16. The tabletop water filter jug 12 is now ready to filter or demineralize untreated water again.

Figures 28 to 30 show a further embodiment of a lid device 18. It differs from the lid device 18 according to the embodiment of Figures 1 to 27 only in the design of the locking device 106. Therefore, only the differences between the two locking devices 106 will be explained below. Furthermore, the same reference numerals are used to designate identical or functionally similar elements and components as in the embodiment of Figures 1 to 27.

In the embodiment of Figures 28 to 30, the retaining strip 166 is somewhat shorter than in the embodiment of Figures 1 to 27. Adjacent to a free end 316 of the retaining strip 166, which points in the direction of the filling opening 90, a locking element 318 in the form of a magnetic retaining element 320 is arranged. The magnetic retaining element 320 cooperates with the magnetic retaining element 136 on the filling opening cover 92 in the closed position to hold and lock the filling opening cover 92 in the closed position in a defined manner. Figures 28 to 30 each show the cover device 18 in the closed position.

When the edge 102 rests against the stop 130 in the closed position, the magnet 140 is aligned above the magnetic holding element 320, which is also designed as a magnet 322. The magnets 140 and 322 are arranged such that in the closed position a south pole of one magnet is opposite a north pole of the other magnet, so that the two magnets 140 and 322 attract each other in the closed position. In the closed position, a greater magnetic holding force then acts between the two magnets 140 and 322 than between the magnet 140 and the holding strip 166. This greater holding force in the closed position is noticeable to the user. In order to move the filling opening cover 92 from the closed position to the filling position, the user must therefore apply a somewhat greater force to overcome the magnetic holding force between the two magnets 140 and 322.

In the embodiment of Figures 28 to 30, the holder 168 is slightly modified compared to the holder 168 in the embodiment of Figures 1 to 27. It has a magnet holder 324 facing the filling opening 90, into which the disc-shaped magnet 322 can be inserted. For this purpose, the magnet holder 324 is designed in a groove-like manner and is open toward the filling opening 90 for insertion of the magnet 322.

In this embodiment, a cover 172 is also provided, covering the holder 168. In this embodiment, the cover 172 is also glued or welded to the cover 88 to enclose the retaining strip 166 and the magnet 322 in a fluid-tight manner, thus protecting them from corrosion.

As explained, in the embodiment of Figures 28 to 30, the locking device 106 is only designed to lock the closed position. Of course, the locking device 106 can also be designed so that locking is only possible in the filling position. In this case, the magnet 322 would have to be positioned adjacent to the retaining strip 166 at its free end facing away from the filling opening 90.

If locking by magnetic holding forces is desired both in the closed position and in the filling position, magnetic holding elements 320 must be positioned at both free ends of the holding strip 166 as described.

In the embodiment of Figures 28 to 30, the locking elements 110 and 318 are thus engaged by magnetic interaction.

For the sake of clarity, it should be noted that in the embodiment of Figures 28 to 30, no locking knobs 122 are arranged or formed on the guide receptacle edge 118 of the guide receptacle 116. Thus, in this embodiment, no mechanical locking can occur in the filling position and the closed position. Of course, it is conceivable to mechanically lock the position that is not locked by magnetic interaction, as explained in detail in the embodiment of Figures 1 to 27.

Figures 31 to 34 schematically illustrate another embodiment of a cover device 18. It differs from the embodiment of Figures 1 to 27 only in the design of the locking device 106.

In the embodiment of Figures 31 to 34, no locking knobs 122 are arranged or formed on the guide receptacle edge 118 of the guide receptacle 116. Nevertheless, in this embodiment, locking of both the closed position and the filling position is realized purely mechanically. In this embodiment, The sliding elements 96 have locking projections 326. A total of four sliding elements 96 and thus four locking projections 326 are provided. Two locking receptacles 328 cooperate with the locking projections 326, which are formed on the cover 88 in the form of sliding surface recesses 330 in the sliding surface 104.

The functioning of the locking device 106 in the embodiment of Figures 31 to 34 will now be briefly explained.

When the filling opening cover 92 assumes the closed position, two of the four locking projections 326 engage the locking receptacles 328. To move the filling opening cover 92 into the filling position, the filling opening cover 92 must be moved away from the filling opening 90, as in the other exemplary embodiments. For this purpose, a somewhat increased force must be applied to disengage the locking projections 326 and the locking receptacles 328. Once these are disengaged, the four sliding elements 96 slide on the sliding surface 104, as in the other two exemplary embodiments, until the filling opening cover 92 reaches the filling position.

The sliding elements 96 are positioned on the filling opening cover 92 such that the other two sliding elements 96 can now snap into the locking receptacles 328 on the cover 88. This snapping or engaging of the filling opening cover 92 on the cover 88 is noticeable to the user. To move the filling opening cover 92 back into the closed position, the procedure must be reversed. Here, too, additional force must first be applied to disengage the locking projections 326 and the locking receptacle 328.

The lid devices 18 of the embodiments of Figures 1 to 27, Figures 28 to 30 and Figures 31 to 34 can optionally be connected to the described can insert 16. The functioning of the Table water jug 10 remains otherwise unchanged, so reference can be made to the above description.

The described embodiments of table water jugs 10 enable the simple treatment of water, especially tap water. Furthermore, they are designed for sustainability, because in the described table water jugs 10, used filter elements 226 can be replaced without also having to replace the housing 218 and the associated housing cover 222. Thus, the filter insert 20 is reusable, except for the filter element 226. Therefore, only the component that is actually no longer usable needs to be replaced.
