Description

The invention relates to a container with an upward pointing opening, on the edge of a circumferential flange is provided for receiving a lid for closing the Container is preferably formed by locking, wherein the lid has a lid edge open at the bottom, which in a cover surface of the cover merges.

Such a container is, for example, from DE 297 05 166 U1 known.

The known container consists of an elastic Plastic material and points in the transition area between the lid surface and lid edge a circumferential, elastic and on the Inner wall of the container adjacent sealing lip, which in the Extension of a peripheral rib on the edge Top of the lid surface in the transition to the edge area is formed, is arranged.

Such a container can also be used with a tool Pry open a lid placed on the container be, such as this from the aforementioned DE 297 05 166 U1 is known.

Such a tool is usually the rotating one Flange of the container interrupted. The tool is mostly as Flap formed, which is articulated on the container wall and is arranged such that an attached lid through a pivoting of the tab outwards or upwards in the area of the tool can be partially raised in order to open the lid to facilitate.

Such a tab can also be equipped with a display device be provided for a first pivoting of the tab after to be displayed on the outside or on the top, as shown, for example, in EP 0 565 967 B2 or EP 1 052 183 A1 is known.

Such containers have been in use for decades u. a. for taking up colors, such as emulsion paints, but also for the inclusion of any other materials used.

A good seal is desirable when the container is closed by an attached lid. Most recently Such containers are often filled in and closed state inserted in a so-called vibrating mixer, using a vibrating plate placed on the lid be clamped. It should be noted that such Containers in the filled state by the mixing movement that in several degrees of freedom can take place, a significant one Are exposed to inertia, so that the tightness in closed state and in the clamped state Bracing using a vibrating plate makes considerable demands be put.

In addition, the containers should be as simple as possible be producible and manageable, including an ergonomic design heard. Finally, the lid of the container in question have as favorable stacking properties as possible often have to be stacked independently of the containers.

So much for a tool with a tab to open the container is provided with the lid on, this is expediently equipped with a display device to a display the first time the tab is opened.

It is important here, the tool and the display device to be designed in such a way that it can be opened for the first time can be seen before the lid edge is partially supported the tool is raised without this with the Display device is visually recognizable.

The invention is therefore based on the object to create improved containers that provide the best possible seal with an associated lid when closed guaranteed.

Furthermore, a container is to be created, which also for Use with vibrating mixers is particularly suitable.

Finally, a container with a tool is to be specified be that has a tab hinged to the container, the when swiveling outwards, a partial lifting of a attached lid allows, with one with the tab combined display device a first pivoting the Tab should be made recognizable to the outside before the lid with the tab can be lifted.

Furthermore, a suitable lid for such a container can be specified.

These and other objects of the invention are achieved by a Container according to one of claims 1, 2, 3, 6, 11 or 12 or solved by a lid according to claim 20. advantageous Further developments of the invention are in the dependent claims under protection.

In a container according to claim 1 by one at the bottom End of the lid edge provided sealing surface that faces outwards and protrudes diagonally downwards from the edge of the lid, and that in one Closed position with lid on the container seals an inner surface of the wall of the container, a ensures secure sealing of the container.

If the lid of the container has a circumferential projection is provided, which is within a of Cover edge of the enclosed area parallel to the cover edge extends and protrudes upward from the cover surface, so this projection is preferably in relation to the diagonally down from the bottom of the lid protruding sealing surface offset to the inside of the lid, so that a Radial distance between the for sealing purposes provided projection of the lid edge downwards and obliquely outward projection on the one hand and for For the purpose of support provided protrusion on the top of the lid is provided.

This ensures that when a Vibrating plate on the protrusion at the top of the lid one favorable force introduction is guaranteed, which in the DE 297 05 166 U1 known container is not the case because of this the sealing surface protruding downwards when a Vibrating plate on the projection at the top of the lid Inside the lid is deformed.

According to claim 2, a particularly reliable seal between lid and container ensures that at least on the lid or on the container a sealing area with a Sealing material is provided by the 2-component technology with the remaining area is connected and made of a softer Material than the remaining area of the lid or container exists, and that with a counter surface of the assigned other Partially seals that are made of a harder material than that Sealing surface exists.

According to the 2-component technology known in plastics production ("2-component spray technology") can be a softer Plastic material firmly with a harder plastic material connect, the most diverse shapes are possible. In this way, a special sealing surface from one softer material in a suitable place on the lid and / or the container to provide a particularly safe To ensure sealing. Here, the place of attachment the softer sealing surface to the respective requirements be adjusted. For example, the soft sealing surface on the Outer surface at an angle at the lower end of the lid edge protruding surface below and outside embedded. About that In addition, it is conceivable, for example, to have such a two-component sealing surface also at the upper end of the container edge or at the assigned one To provide the inner edge of the lid. In addition, there are numerous other locations for such a 2-component sealing surface conceivable.

In the container according to claim 3 is by one of the Top of the lid surface essentially parallel to the lid edge extending projection, which is opposite the edge of the lid upwards protrudes out and is formed as a bead that for Underside of the lid is open, a particularly good one Lids can be stacked because of the beads Centering can be made. In addition, the Manageability of the container is considerably simplified, provided the lid should be closed by pressing by hand, since now a wide pressure area is available, as opposed to the webs known in the prior art.

In the container according to claim 6 is on the wall of the Container a conical sealing area widening outwards provided with a correspondingly shaped sealing area of the lid edge interacts.

With such a configuration, the seal between Lid and container significantly improved since now flat sealing area is created. As a result of the tapered Good centering is also guaranteed. Moreover the sealing surface is insensitive to damage, in Contrary to conventional tongue and groove seals.

If such a container with a tool to pry open Provide cover in the area of the tool, so the tapered Design of the sealing surface has the particular advantage that the Tab of the tool considerably higher on the container wall can be articulated than this with conventional solutions Case is. The pivot point of the tab (film hinge) can thus be moved closer to the top of the container, which leads to a significantly longer lever arm, which leads to a Prying up the edge of the lid is simplified.

In a container according to claim 11, the tab is on their two transitions to the flange each through a recess from Flange separated, which is approximately from an upper axis of rotation of the Tab out to about the area of the bottom of the Tab extends and ends in a tearable web that the Tab connects to the flange on its face.

This ensures that when it is opened for the first time the tool, d. H. when swiveling from one to the other Container position in the closed position from the outside or above, the tearable web is first damaged, so that the first time the tab is opened is displayed. Only after that leaves the tab swivel as far outwards or upwards that lifting the lid in this area is made possible.

Furthermore, this configuration enables the tab directly into the circumferential flange of the container integrate, the tear-off webs simply by dividing lines or Recesses can be formed. This leads to a particularly simple manufacture. The bottom edge of the tab itself can, for example, be formed flush with the flange but also protrude downwards or upwards opposite the lower edge of the flange.

In the design of the container according to claim 12 at least one support web supported on the wall of the container provided that is firmly connected to part of the tab, through at least one recess from the rest of the tab is separated, the support web over at least one Indicator element, preferably a tearable web, with the rest of the Tab is connected such that a first pivoting the tab to the outside to damage the Indicator element leads.

In this way, the indicator element can be part of the tab be formed, for example more in the middle of the tab be relocated, making it easier to see is reached when the indicator element is damaged.

Likewise, simple manufacture of the Allows display device as part of the tab, again it is ensured that when the tab is opened for the first time First the indicator element is damaged before the tab can be pivoted outwards or upwards until the Edge of the lid can be partially raised.

It is understood that the above and the Features of the invention to be explained below not only in the specified combination, but also in others Combinations or alone can be used without the Leave the scope of the invention.

Fig. 15 is a partial section through the container along the line ABCD according to Fig. 14.

In Fig. 1, a container according to the invention is shown in perspective without the associated lid and overall designated by the number 10 . The container 10 and also the associated lid 30 according to FIG. 2 consists of plastic, for. B. made of polyethylene. The container 10 has a wall 13 which encloses an opening 12 at the upper end and runs out in an upper edge 18 . This is followed on the outside by a circumferential flange 14 which is designed to receive the associated cover 30 .

The container 10 shown in FIG. 1 is designed, for example, to hold emulsion paint and has an elliptical shape. On the two longitudinal edges of the flange 14 , a hole 16 is provided opposite each other, into which a handle can be hung at one end.

The container 10 is shown in FIG. 1 is further provided with a tool 20 having a flap 22 which is hinged in the vicinity of the upper edge 18 at a pivot axis 24 on the flange 14. In the following, this pivot axis 24 is designed as a film hinge in a manner which will be explained in more detail below. The tool 20 is also provided with a display device which indicates a first opening of the tab 22 by pivoting it outwards or upwards. For this purpose, two tear-off webs 26 , 28 are provided on the left and on the right edge of the tab 22 , the structure and function of which will be explained in more detail below.

The cover 30 is enclosed by a peripheral cover edge 32 , which includes a cover surface 34 . On the upper side of the lid surface 34 a projection 36 is provided as a circumferential rib projecting in parallel to the edge of the lid 32 on the top side of the lid surface 34 upward and having a certain distance from the lid towards the center with respect to the lid rim. The projection 36 is interrupted at several points in the circumferential direction, as can be seen from FIG. 2.

The more detailed design of the container with the lid shown in FIGS. 1 and 2 it can be seen from the enlarged representation according to FIG. 3, wherein said, however, is slightly modified whole with 30 a designated lid compared to the embodiment of the lid 30 according to FIG. 2.

In this representation, as in all the following Representations are corresponding for corresponding parts Reference numbers used.

The wall 13 connected to a bottom surface of the container 10 merges upwards into a conical sealing area 40 with an oblique sealing surface, and runs out in the upper edge 18 of the container, which extends approximately horizontally, ie approximately parallel to the lid base. The upper edge 18 is followed by a short downwardly extending shoulder 42 , from which the flange 14 extends obliquely outwards and downwards with an inclined surface 46 , which ends in a projection 48 . This projection 48 is followed by a groove 49 , at the lower end of which a shoulder 53 is formed, which, when the cover 30 is opened by means of the tool, by pivoting the tab 22 upwards serves as a stop surface for the lower edge 52 of the cover.

The cover 30 a has on the underside of its cover surface 34 an edge-side sealing web or a sealing surface 38 which extends obliquely downwards and outwards from the outer edge of the cover surface 34 . This sealing surface 38 protrudes obliquely outwards in the direction of the wall 13 , as is schematically indicated by the dashed area 39 in FIG. 3. In reality, of course, the sealing surface is pressed together from the wall 13 or the wall 13 is slightly curved outwards at this point.

A corresponding cone-like sealing area 41 of the lid 30 a is assigned to the conical sealing area 40 of the container 10 .

In this way, a sealing area with oblique, superimposed sealing surfaces is created between the container 10 and the inside of the lid edge 32 , which ensures a good seal and also supports centering.

An annular locking web 50 on the underside of the lid edge 32 is assigned to the shoulder 42 in the region of the upper edge 18 of the container 10 . This avoids opening the cover 30 a if the inner seal should fail in the area of the sealing surfaces 40 , 41 or 38 .

The shoulder 48 , in which the inclined surface 46 of the flange or the tab 22 ends, is assigned an annular web 54 in the region of the lower end of the lid edge 32 , which ensures that the lid 30 is locked further with the container 10 in the closed position.

The swivel axis 24 , to which the tab 22 is pivotably connected to the flange 14, is located somewhat below the shoulder 42 adjoining the upper edge 18 of the container 10 . This pivot axis 24 is designed as a film hinge, as will be explained in more detail below with reference to FIGS. 6, 8 and 14. According to Fig. 3 is formed between the upper end of the cover surface 34 of upwardly projecting rib 36, which runs parallel to the edge of the lid 32, a certain distance AH, so that the projection or the rib 36 opposite the upper end of the lid rim 32 to protrudes above by the amount ΔH. When the container is clamped in a vibrating mixer, an attached vibrating plate thus rests on the projection 36 and thus presses on the top of the lid surface 34 . Since the rib 36 is arranged at a distance from the lid edge 32 in the direction of the center of the lid, this introduction of force pushes the lid surface 34 downward and at the same time presses the sealing surface 38 against the wall 13 of the container 10 .

FIG. 4 shows a container 10 with a lid which is slightly modified compared to the embodiment according to FIG. 3 and which corresponds in its embodiment to the lid according to FIG. 2 and is therefore generally designated by the number 30 .

The only difference from the embodiment according to FIG. 3 in the case of the cover 30 is that the cover surface 34 is flush on its underside and passes directly into the conical sealing region 41 via a shoulder 35 running parallel to the wall 13 of the container 10 .

A further modification of the container is shown in FIG. 5 and is designated overall by the number 10 b. An associated cover is generally designated with the number 30 b. A first difference to the previously with reference to FIG. 3 embodiment described is that the upper edge b 18 of the container 10 is formed as upwardly projecting annular rib 18, both on the outside and on the inside by a respective associated annular rib 50 or 51 is enclosed on the underside of the lid edge 32 . This creates a tongue and groove seal. Further, the container 10 b and the lid rim 32 is formed not a cone-shaped sealing area between the wall. 13

For the purpose of a good seal between the lid 30 b and the container 10 b, as in the embodiment according to FIG. 3, the sealing surface 38 is provided, which protrudes obliquely downwards and outwards from the lid surface 34 . In addition, injected at the lower end in the outer region of the sealing surface 38 is a 2-component sealing surface of softer material in 2-K technology, the seals of the container 10 b with the harder material of the associated wall. 13 Otherwise, the design of container 10 b and lid 30 b corresponds completely to the design previously described in FIG. 3. The latching of the lid 30 b with the container 10 b is now essentially taken over by the tongue and groove connection between the upper edge 18 of the container 10 b and the two ring webs 50 , 51 on the underside of the lid edge 32 . The two-component sealing surface ensures a particularly good seal between the lid 30 b and the container 10 b without a conical sealing area 40 , 41 as is necessary in the embodiments according to FIGS. 3 or 4.

The tool 20 , which is only indicated in FIG. 1 and serves to pry open the lid of the container, is explained in more detail below with reference to FIGS . 6 and 7.

The tool 20 has a tab 22 which interrupts the flange 14 in the region of the tool 20 . The outer contour of the tab 22 corresponds completely to the outer contour of the flange 14 and only protrudes somewhat on its underside from the underside of the flange 14 , as can be seen from FIG. 6. The tab 22 is hinged at its upper end in the immediate vicinity of the upper edge 18 of the container by means of a film hinge 24 on the flange 14 . The film hinge 24 , which is only indicated by dashed lines in FIG. 7, consists in a weakening of the material, as a result of which pivoting is made possible at this point.

The tab 22 is separated at its two lateral transitions to the flange 14 by a recess 64 and 66 from the respective end 68 and 70 of the flange 14 . These recesses 64 and 66 each end in a horizontally widened recess 65 and 67, respectively. Below this recess 65 or 67 , the tab 22 is in each case connected to the flange end 68 or 70 via a tearable web 72 or 74 , which is separated by a further recess 71 or 73 on the underside of the respective end 68 or 70 of the flange 14 is separated.

The tab 22 has a reinforcement 60 in its center for reinforcement. To the right and left of this bracing of the tab 22 , support ribs 62 are provided on the wall 13 of the container for supporting the pivot axis 24 or the film hinge. The flange itself is also supported against the wall by a plurality of support ribs, of which only the two support ribs 76 and 78 can be seen in FIG. 6, which are formed at the ends 68 and 70 of the flange 14 .

When the tab 22 is opened for the first time from a closed position by pivoting the tab outwards or upwards, the webs 72 and 74 which can be torn off are first torn open in the region of the lower end of the flange 14 and only then is it possible to lift the lid in place in this area.

A modified version of the tool for opening the container is shown in FIGS. 8 and 9 and is generally designated by the number 20 c.

The tab 22 is in turn pivotally received at its upper end on the film hinge 24 . Recesses 64 and 66 run from the film hinge 24 on both sides of the tab 22 and completely separate the tab 22 from the respective ends of the flange 14 at their side edges. The display device for displaying the first pivoting of the tab from a closed position to the outside is no longer formed between the side edges of the tab 22 and the ends of the flange 14 , but rather within the tab 22 at two locations. For this purpose, a support web 80 is provided, which extends downward from the film hinge 24 and which is fixedly connected to the wall 13 of the container via a support rib 62 . This support web 80 is separated from the other areas of the tab on both sides by a recess 81 or 82 , which extends from the film hinge 24 down to the end of the support web 80 . A further recess 83 is provided below the support web 80 , through which two thin tear-off webs 84 and 85 are delimited, via which the support web 80 is connected to the remaining area of the tab 22 .

When the tab 22 is opened for the first time, the two tear-off webs 84 , 85 are thus torn open before the lid can be raised after the tab has been pivoted further outwards and upwards.

The opening movement is explained in more detail with reference to FIGS. 10 and 11. While the lid is 30 a of FIG. 10 locked in its closed position on the container edge, the lid rim 32 by tearing off the tear-off webs 84, 85 and further pivoting of the tab 22 is lifted upwardly, as shown in FIG. 11 to be seen in more detail is , The groove 49 in conjunction with the projection 53 on the tab 22 serves to take the lower end 52 of the lid edge 32 with it .

Another modification of a container 10 with a lid is shown in FIGS. 12 and 13. The lid, designated as a whole by 30 d, differs from the lid previously explained with reference to FIG. 30b in that the projection 36 d projecting upward from the lid surface 34 is not designed as a rib, but as a bead that extends from the underside of the lid Lid 30 d bulges upwards and is open to the underside of lid 30 d. Since the center of the bead is also offset from the sealing surface 38 towards the inside of the lid, force application here also leads to a spreading of the sealing surface 38 outwards against the wall 13 of the container 10, for example via an attached vibrating plate.

The projection 36 d or the bead improves the stackability of the lid 30 d and ensures centering, while at the same time facilitating manual closing of the lid.

A further modification of the tool for lifting the edge of the cover is shown with reference to FIGS. 14 and 15 and designated 20 d in the left half of FIGS. 14 and 15, while a modified embodiment in the right half of FIGS. 14 and 15 is 20 e is designated.

In the embodiment according to the left half of FIG. 14 or FIG. 15, the tool 20 d has a tab 22 d, which on its side edge through a recess 64 , which extends downward from the film hinge 24 , towards the respective end the flange is completely separated. Immediately adjacent thereto is a support web 80 d which runs downward from the film hinge 24 and is formed in one piece with a support rib 62 d arranged underneath, on the outer surface of which the support web 80 d is formed. The support web 80 d is separated from the rest of the tab 22 d by a recess 81 d, which extends downward from the film hinge 24 approximately to the lower edge of the flange 14 and runs out from there in the direction of the flange end. Between the lower end of the support web 80 d and the tab 22 d, two easily tearable webs 84 d, 85 d are provided, which are arranged perpendicular to the film hinge 24 .

As can also be seen from the left half of FIG. 15, the support web 80 d and the associated part of the tab 22 d in the edge region are set back in the direction of the wall of the container, thereby ensuring better visibility and at the same time protecting against unintentional use To open.

The embodiments of the tool 20 e according to the right half of FIG. 14 or Fig. 15 d of the left half is not the Figs. 14 and 15, wherein, however, the support web 80 e and the tab 22 E substantially corresponds to the embodiment of the tool 20 are set back in the edge area in the direction of the wall of the container. The support web 80 e is in turn received on a support rib 62 e which extends outward from the film hinge 24 and ends in an enlarged recess 86 at the lower right or left edge of the tab 22 e. Within this recess 86 , the remaining part of the tab 22 e is connected to the supporting rib 62 e via two easily tearable webs 84 e, 85 e running parallel to the film hinge 24 .

In both versions, the tear-off webs 84 d, 85 d and 84 e, 85 e are easily recognizable and are first torn open when the tab 22 d or 22 e is opened before a lid that has been put on is made possible to be lifted.
