An independent claim is also included for a drinking bottle.

Description

The The present invention relates to a closure for a drinking bottle with a closure bottom and a closure top, wherein the closure upper part has a flow opening opening into a mouthpiece and rotatable with respect to the closure bottom between a Closed position, in which the flow opening is closed and an open position, in which the flow opening open is, is displaceable, further comprising a via the closure top stülpbarer Cover is provided, which is hinged to the closure top and a latching lug, and wherein on the closure lower part provided with the locking lug engageable locking is. Furthermore, the present invention relates to a drinking bottle with such a closure.

A drinking bottle with such a closure, as indicated in the preamble of claim 1, is known from DE 196 30 579 C1 known.

Similar closures are for example also from the DE 93 03 734 U1 as well as the DE 44 95 238 C1 known. Since such closures are used primarily for drinking bottles, which are not intended for home use, but are taken by the user, for example, for sports or hiking, but also on a large scale by children in the school or kindergarten, in which case the bottle mostly is placed in a bag together with other items, it is of great importance that the closure seals the bottle well and prevents leakage of introduced into the interior of the bottle liquid safely.

While the known closures are designed to securely close the flow opening in the closed position of the closure, there is often the problem that the user thinks that he has brought the closure top to the closed position, but then it turns out in hindsight that the closed position has not been fully achieved. In particular, it is in the known closures, as well as in the DE 196 30 579 C1 shown, usually not possible to see by mere inspection whether the closed position has actually been achieved, but this must be checked by turning the shutter until the rotary end position is reached. Especially with closures that have been in use for some time and have become somewhat stiff due to abrasion, or when liquid has penetrated between the closure base and the closure top, which leads to sticking of these components, it may happen due to such induced stiffness, it is erroneously assumed that the shutter has reached the closed position. The result of this is that when the bottle is tilted, the liquid taken up in the bottle can run out, so that not only the contents of the bottle are lost, but also any items that are housed together with the bottle can be soiled or even damaged.

It is therefore an object of the present invention, a closure of The aforementioned type and a drinking bottle to create at which the closed position by mere Hinschen is recognizable.

According to the present Invention achieves this object in a closure of the aforementioned Sort of solved by that provided on the closure lower part locking only in the closed position of the closure top cooperates with the latch. Thereby, that in such a closure locking the lid only then takes place when the closure top in its closed position across from the bottom of the closure, the operator recognizes unequivocally, whether the closure is really sealed or the closed position not quite reached yet. Unlike the known drinking bottles, in which the lid designed as a dust cap over the Clasp put over and can be locked when the closure top in a Intermediate position between its open position and its closed position is carried out in the closure of the present invention only then locking the lid when the flow opening is actually sealing is closed.

The The object underlying the invention is further by a dissolved bottle having such a closure.

preferred Embodiments of the invention will become apparent from the dependent claims.

Especially the catch can be provided laterally on the outside of the lid its and the latch are formed by a groove, which at one provided from the closure part upwardly projecting web. Here, the locking takes place on the outside of the lid and thus for the Operator visible over a relatively small Verdrehweg between the provided on the lid locking lug and the groove in the upwardly projecting from the closure bottom Web.

Preferably, means for biasing the lid are provided in an open position, so that the user reaching the closed position of the closure not only on the lock of the Cover opposite the closure base or the position of the latch against the locking recognizes, but already because the lid when slipping on the closure top remains in this position and does not jump back to its open position.

To the Pretensioning the lid in its open position is preferably provided on the underside of the lid, an elastic member, which is in the closed position the lid elastically against the top of the closure top invests. The elastic member may be, for example, a silicone spring be formed, in particular a cup-shaped silicone component, which via a provided on the underside of the lid provided thorn-shaped projection.

Preferably are further means for locking the lid in the open position provided so that when open Cover this in the open position remains and does not hinder the user while drinking.

While to open and closing of the closure, the closure top against the closure bottom rotated must, unlike some of the known closures, the Closure top not be touched in the area of the mouthpiece, resulting from hygienic establish is advantageous.

While that Closure top and the closure bottom in principle so can be designed that to open and closing the flow opening the closure top only a rotational movement relative to the Closure bottom performs, for example, by opening in the closure top and closure bottom are provided, which by turning these two components optional in coincidence with each other or in cover to the respective other component provided sealing surfaces can be brought such a closure To effect the closure, it is to achieve a good seal advantageous if the closure is designed so that the closure top upon rotation with respect to the closure bottom an axial Relocation experiences in the course of which the flow opening is closed or opposite opened to the interior of the bottle becomes. This leaves For example, accomplish that between the top closure and the closure bottom is a bayonet connection or, more preferably, a threaded connection is provided.

Preferably are further means for locking the closure top with respect on the closure bottom in the closed position and / or the open position intended. Is for example between the closure shell and the closure bottom provided a threaded connection, so can it is in such locking means to a recess in the Thread deal, in which a cooperate with the thread to the thread Thread provided projection when reaching the opening or closed position retracts. While Such a lock not only an unwanted twisting of the Closure top part from the opening or closed position prevents such locking also facilitates the user the recognition of the achievement of the respective final rotation position.

Around to prevent the twisting of the closure top against the Bottom closure of the lid against the upper closure part twisted and possibly is sheared off, is preferably also between the lid and at least one anti-twist device is provided for the closure upper part, with the lid closed, twisting the lid relative to the Locking top prevents. Such a rotation can For example, be accomplished by the fact that on the inside the lid, where this the closure top in the closed position surrounds, a bulge or a projection is provided, the or with a corresponding provided on the closure top Projection or a bulge cooperates.

at a further advantageous embodiment of the invention is attached the closure lower part further provided a vent valve, which when using the closure with a drinking bottle, a stream of air in the direction of the interior of the bottle, but allows an outflow of Fluid, d. H. of liquid, Steam or gas, prevented from the interior of the bottle. By means of a Such ventilation valve may be a result of drinking from the bottle in the interior Negative pressure through from the outside pouring into the bottle Air are balanced.

Around To facilitate the cleaning of the closure are advantageously the closure top, the closure bottom and the lid detachably together connected, preferably for these components materials chosen be that for a cleaning of the same are suitable in a dishwasher.

While a closure, as proposed herein, in principle could also be firmly connected to a drinking bottle, for example by the closure bottom in one piece with the Bottle body is connected, it is preferred that the closure is designed for releasable connection with a drinking bottle, so as to facilitate a cleaning of both the closure and the bottle. For this purpose, for example, the bottle in the region of its neck have an external thread and the closure lower part have a cooperating with this internal thread. Instead of a threaded connection could also be provided also a bayonet connection or a simple clamping connection between the closure bottom and the bottle.

Preferably Furthermore, a seal is provided, which in with the bottle Connected lock for a seal between the closure and bottle ensures. Such For example, gasket may be provided by one provided in the closure bottom O-ring formed when screwing the closure base on the bottle against the neck of the bottle.

At the formed as drinking spout closure top 16 is a hinged lid 24 hinged, the closure top in its closed position 16 completely covered. On the inside of the lid 24 is a thorn 26 provided on the a cup-shaped spring member, preferably a silicone spring 28 , is attached to the lid 24 to bias in its upwardly pivoted opening position. In the in 2 shown closed position is the lid 24 by means of a on the lid 24 provided latch 30 placed in one on the closure bottom 14 provided recess 32 engages, locks, as will be explained in more detail below. In the lower part of the closure base 14 is also a vent valve 34 provided that can flow through while drinking from the bottle of air in the bottle interior to compensate for the otherwise resulting in drinking negative pressure in the interior of the bottle.

For sealing the closure base 14 opposite the bottleneck is an O-ring 36 intended. While the O-ring 36 In principle, it could also be provided in such a way that, when the closure is screwed onto the neck of the bottle, it is inserted between one on the closure bottom part 14 provided projection 38 and the top 40 of the bottleneck, the o-ring is as in 2 is shown, preferably in a near the lower edge of the closure lower part 14 provided groove and applies when screwing the closure on the bottle against a provided on the inside of the bottle neck projection so that the liquid located inside the bottle can not penetrate into the space of the threaded connection between the closure and the bottle, otherwise could lead to sticking of the threaded connection and the unscrewing of the closure of the bottle difficult.

As in the 1 and 2 can be shown on the closure bottom 14 an eyelet 42 be provided to attach, for example, a carabiner, a ring, a Sellstück or the like, so that the bottle can be hung for example on a belt.

In the 3A to 3D is the outer part 10 of the closure base 14 shown in different views, where 3A a view from below, 3B a side view, 3C a perspective view from above and 3D a perspective view from below shows. The inner part 12 of the closure base 14 is in the 4A and 4B shown in a perspective view from above or below. The two parts of the closure base 14 are preferably made of plastic, for example as injection molded parts. The inner part 12 and the outer part 10 of the closure base 14 can be easily connected with each other, if that in 3 outer part shown 10 in the area of its upper edge several breakthroughs 46 has, during assembly of the closure bottom 14 with locking projections or snaps 48 located at the top of the in 4 shown inner part 12 of the closure base 14 are provided to be locked. Furthermore, an exact positioning of the inner part 12 with respect to the outer part 10 can also ensure in one or more of the breakthroughs 46 positioning grooves 50 be provided in the corresponding at the projections 48 provided positioning lugs 52 intervention. In the embodiment shown in the figures is also on the inside of the outer part 10 of the closure base 14 a locking nose 54 provided with one on the inner part 12 of the closure base 14 provided locking groove 56 cooperates, whereby on the one hand for a locking and anti-rotation between inner part 12 and outer part 10 of the closure base 14 is taken care of and ensured by the other hand, that the inner part 12 and the outer part 10 can be joined together only in a certain rotational position. In 4A is also a on the inner part 12 of the closure base 14 provided thread 58 (see also 1 ), with which the closure in a corresponding connection thread 60 (please refer 1 ) can be screwed to the bottleneck.

As in particular in the 3B and 3C can be seen, has the closure bottom 14 a thread 62 on which to the connection of the closure lower part 14 with the in the 5A and 5B shown closure top 16 serves. While 3B an embodiment in which the connecting thread 62 has two rotationally symmetric threads (of which in 3B only one is visible), understood that the thread 62 can also have more than two threads.

The closure top 16 is a substantially lid-shaped member having a centrally located substantially tube-like segment, which at its upper end as a mouthpiece 18 is formed and at its lower end with a seal 64 is provided, which is preferably designed as a molded in two-component process TPE profile seal. As in particular in 2 can be seen, the closure shell sits 16 so on the closure bottom 14 on that the the flow opening 22 surrounding tubular section 66 of the closure shell 16 in a likewise tubular section 68 (please refer 4A ) of the closure base 14 engages so that the closure seal 64 of the closure shell 16 regardless of its position with respect to the closure bottom 14 against the wall of the tubular portion 68 of the closure base 14 invests. As in particular in the 4A and 4B can be seen, are within the tubular area 68 on the closure bottom 14 several flow openings 70 provided by the liquid with the closure open from the inside of the bottle in the tubular area 68 of the closure base 14 and thus into the flow opening 22 of the closure shell 16 can occur. If, however, the closure top 16 by rotation with respect to the closure bottom 14 shifted in the closing direction, the in 5A shown thread segments 72 in the connection thread 62 of the closure base 14 slide down, then settles at the end of the downward movement of the closure top 16 the sealing seal 64 sealing against the flow openings 70 and close it. To the grip of the closure shell 16 for a rotation opposite the closure lower part 14 To improve, the lock shell 16 on its outside, which may be cylindrical or domed, with a surface texture 74 be provided, the surface structure 74 at the same time for introducing design elements, such as logos or the like, can be used.

For hinging a lid 24 as he is in the 6A and 6B is shown on the closure top 16 a pivot pin 76 provided in the two axle bolts 78 of the lid 24 intervention. The axle bolt receptacle 76 This can be designed so that the lid 24 in the recording 76 can be pivotally locked, however, for example, for cleaning purposes or the lid 24 against another cover 24 to exchange with different design, from its hinge connection with the closure top 16 can be solved. To the lid 24 in the open position to lock, the in 6B shown lid 24 a locking cam 80 on, with one on the closure top 16 provided catch 82 interacts when the lid 24 fully opened. The lid 24 can also reinforcing ribs 84 , as well as labels or design elements 86 which, in particular when it is the lid 24 is a plastic injection molded part, in the lid 24 can be molded. In order to Prevent a user from twisting the closure top 16 opposite the lid base 14 at the same time the lid 24 opposite the closure top 16 twisted, is on the inside of the lid 24 on the opposite side of the hinge serving as a rotation indentation 88 provided, with the lid closed 24 with one on the closure top 16 provided bulge 90 interacts. In 6A is also the lid 24 provided latch 30 to see if the lid 24 is closed and the closure top 16 in its closed position with respect to the closure bottom 14 is turned into the bottom of the closure 14 provided recess 32 driveway and the lid 24 locked there.

To the closure top 16 can lock in the closed position, in the bottom of the closure 14 provided thread 62 a recess 92 be provided, in which a corresponding on one of the thread segments 72 provided, not shown in the figures locking cam engages when the upper closure part 16 has reached the closed position. At the top of the thread 62 is also preferably a stop 94 provided, against which the respective thread segments 72 of the closure shell 16 applies when the open position is reached. To the closure top 16 from the closure bottom 14 to solve, is the closure shell 16 about the stop 94 Turned out further, allowing it to reach the unthreaded area 96 from the closure bottom 14 comes free. To when reassembling closure bottom 14 and closure top 16 to facilitate the alignment of these two parts to each other, is on the closure bottom 14 within the tubular section 68 on, centering cross 98 provided, which in the assembled state in the flow opening 22 protrudes.

Referring again to 4B it can be seen that in the closure bottom 16 a recording 100 is provided to the, ventilation valve 34 which is in 7 shown is to install. The ventilation valve 34 is preferably designed as an elastic member having a frusto-conical barb 102 has to the aeration valve 34 in the recording 100 to introduce and hold it, and this over a circumferential, mushroom-shaped lip 104 for sealing the interior of the bottle to the outside. In such an embodiment of the ventilation valve 34 an internal pressure prevailing in the interior of the bottle intensifies the sealing effect of the ventilation valve 34 , whereas a negative pressure in the interior of the bottle, as it arises when drinking from the bottle, to a lifting of the mushroom-shaped lip 104 from the closure bottom 16 leads, so that air can flow into the interior of the bottle. The ventilation valve 34 is laterally offset and, as in 2 is shown, also axially offset with respect to the centrally arranged flow openings 70 arranged, which has the advantage that the air flowing into the interior when drinking air does not interfere with the through the flow openings 70 leaking fluid connects and thus disturbs the fluid outlet.

To assemble the closure, the inner part 12 of the closure base 14 in the outer part 10 of the closure base 14 used and locked there. Then the O-ring 36 on the closure bottom 14 mounted and the vent valve 34 in the recording 100 of the closure base 14 plugged in. Subsequently, the lid 24 in the Achsbolzenaufnahme of trained as drinking spout closure top 16 clipped and the closure shell 16 with lid 24 on the closure bottom 14 put on and screwed into the thread provided for this purpose. Now the complete closure unit can be screwed onto the drinking bottle, either before or after the silicone spring 28 on the lid 24 provided mandrel attached and a carabiner or other retaining element in the on the lower closure part 14 provided eyelet 42 is introduced.

The use of the closure is very simple. In particular, the closure top is used to open the closure 16 turned counterclockwise over the provided on the thread segments lock position detent until the recess 32 on the closure bottom 14 the catch 30 of the lid 24 releases and the lid 24 due to the silicone spring 28 spring preload springs open. In this position, a pressure equalization between the bottle interior and the atmosphere can already take place, since the rotational movement of the closure upper part 16 a simultaneous axial movement of the same causes and thus the closure seal 64 the flow openings 70 in the shutter releases. By further rotation of the closure top 16 until the drinking stop stops the flow opening 20 completely released. Will the lid 24 so far pivoted that the lid 24 provided locking cam 80 in the top of the lock 16 provided catch 82 hooked up, that's how the lid gets 24 fixed for drinking.

To close the bottle is either the lid 24 overcoming the spring preload of the silicone spring 28 over the closure top 16 slipped and then brought by rotation in a clockwise direction to lock position catch. On the other hand, the closure top 16 even with the lid open 24 first until the lock be rotated and then the lid 24 pressed down until its catch 30 into the recess 32 locks. In any case, the user reliably recognizes that the closure is completely closed, because only in this position the lid 24 opposite the closure bottom 14 can be locked.
