EP2121466B1 - Closure device for a container - Google Patents

Description

The invention relates to a closure device for a container, in particular for bottles, said closure device comprising a base member which is attachable to an opening of the container and having a discharge opening for dispensing located in the container media. Furthermore, the closure device comprises a lid that can be moved back and forth between a completely closed and a fully opened opening, in order to enable the delivery of in particular a flowable medium from the container.

Closure devices are known in a variety of forms and are usually made of a plastic material, but may be made of other materials, e.g. Metals, to be made. A base member typically includes means for attaching the base member to an opening of the container, such as a bottle neck, in particular an internal thread may be provided so that the closure device can be screwed onto the bottle neck.

From the base member preferably extends a spout, in particular a spike-shaped spout, which can also be enclosed, for example, when drinking from the container from the mouth of the drinking person.

In particular, in the cases where aerated liquids may be received in the container, increased pressure may develop in the container. Even with non-carbonated liquids, a pressure difference can be built up, for example, when the container is transported to different heights, as is the case for example when hiking in the mountains. Weather changes can already lead to corresponding pressure differences. When opening the closure device, ie when opening the lid, it may therefore happen that the pressure equalization takes place very suddenly, wherein the stored in the container medium may accidentally flows out of the container.

From the EP 1 332 097 A For example, a closure device is known which has a degassing channel between a spout and a top wall which is closed in the closed position of the lid.

It is an object of the present invention to provide an improved closure device in which in particular prevents this unwanted leakage of the product located in the container or at least the amount of the outflowing medium is greatly reduced.

This object is achieved by a closure device according to claim 1, the claims 2 to 12 relate to particularly advantageous embodiments of such a closure device.

According to the invention the closure device is formed so that the lid has at least one defined intermediate position between the fully closed and the fully open position, wherein the closure device has at least one degassing channel which is launched in the fully closed position of the lid and in the intermediate position of the lid allows pressure equalization between a side facing the container interior of the closure device and the environment. With such a closure device according to the invention, the lid can be opened as it were in a two-stage process, in a first step from the fully closed position to the defined intermediate position, and in a second step from the defined intermediate position to a fully open position.

A closure device has a defined intermediate position in the context of this invention, for example, if during the opening process of the lid from the fully closed to an open position, at least one intermediate position or position, via which the opening process of the lid, at least in a conventional operation or Actuation, can not be guided steadily and smoothly, ie, there is a position that differs in any way with respect to the opening operation and the handling of the user during the opening of the lid. The distinction can be made by increased force, by changing the direction of movement of the lid during opening, even for a short time, by operating a device, for example by moving a bolt that allows, for example, the movement of the lid from the closed position only in the defined intermediate position, a movement beyond it but only by pressing the bolt or any other actuator allows, or be implemented by any other means.

The user therefore automatically opens the lid of the closure device only until the defined intermediate position in which the opening process automatically, if necessary, even for a very short time, pauses or at least delayed, at least during normal use of the device, and automatically a pressure compensation over the provided at least one degassing can take place. Due to the fact that only the degassing is opened while the discharge opening is still substantially closed, no medium at this time exits, but there is a controlled pressure equalization without unwanted discharge of the medium contained in the container instead.

In a second step, the user can then move the lid from the intermediate position to a fully open position. Since at this time already a pressure equalization is at least largely completed, it is ensured that no medium can escape. It should be noted that the provision of the defined intermediate position can be made stronger or less pronounced, so that the closure device can be adapted to the particular stored in the container media. For example, if a carbonated liquid stored in the container, a closure device according to the invention may preferably be used in which the defined intermediate position is more pronounced, especially for example the force required to overcome the defined intermediate position deviates more from the otherwise required force when opening the lid, so that the lid automatically remains longer in the defined intermediate position during a normal opening operation of the user.

It should be noted at this point that for a possibly required pressure equalization in the intermediate position of the lid, only a very short period is required, so that the only very short residence time of the lid in the intermediate position during the opening process for the user in no way disturbing is perceived as annoying. Furthermore, the user must exercise no caution, since the pressure equalization takes place automatically in the defined intermediate position. It should also be noted that, due to the provision of a defined intermediate position, even if it is automatically taken only for an extremely short time, for example only for a fraction of a second, the possibility is created for the user, in the case of a very high 4

Pressure differential that needs to be compensated to respond. The user moves the lid namely in the defined intermediate position and there is a very high pressure difference, for example in carbonated drinks that have been shaken before, the automatically occurring pressure equalization is often audible to the user, in particular, for example, the degassing channel formed be aware that a pressure equalization will take place acoustically noticeable. Although this happens only in fractions of a second, it is typically sufficient for the user to pause, as if in reflex, in the opening process.

In a preferred embodiment of the closure device, this includes a stop device, which is preferably designed so that when moving the lid from the fully closed position to the fully open position, a greater amount of force is required to move the lid beyond the defined intermediate position , This increased effort ensures that during the opening movement of the lid automatically dwells at least for a short period of time in the defined intermediate position to ensure the required pressure equalization. Furthermore, the user automatically recognizes this defined intermediate position, wherein even in the event that a particularly high pressure difference must be compensated, the lid for a longer period in the intermediate position can hold until it is completed. He is assisted by the automatic "finding" of the intermediate position, for example by the increased effort.

According to one aspect of the present invention, a stop device is designed so that the movement sequence when opening the lid is unsteady, ie, the range of the defined intermediate position, the movement, for example, the direction of movement, at least temporarily and easily changed. Another possibility for a stop device is to provide, for example, a bolt or other element that must be additionally actuated to overcome the defined intermediate position. It is also possible that a stop device is designed so that a predetermined pressure must be exerted at a certain point of the closure device to overcome the defined intermediate position, which in particular in the case of the typically made of plastic closure devices which are at least partially elastic is a preferred embodiment.

A stop device in the sense of this invention is therefore to be understood to the fullest extent possible, and also includes delay devices, locking devices, latches, actuators or other devices, which in any way ensure that the movement process when opening the lid to overcome the defined intermediate position, at least during a movement from the closed position to the open position, delayed, inhibited, impeded or otherwise affected.

Preferably, both the base element and the lid each comprise at least one stop element, which are formed so that they at least partially abut each other in the defined intermediate position of the Dekkels. In particular, at least one of the stop elements is designed so that it is elastically yielding. These embodiments of the or the stop elements is a particularly simple and effective realization of the closure device with a defined intermediate position and in particular with an intermediate position, which can be exceeded, at least during the opening process, only by a higher effort by the user.

In a particularly preferred embodiment, the base member comprises a spout, which is preferably formed substantially dome-like, preferably provided on the outside of the spout, at least over a portion of the circumference, a bead-like element. This bead-like element can serve as a stop element or as a resistance element, which interacts with an element of the cover, so that the defined intermediate position is provided in a particularly preferred manner.

It should be noted at this point that such a bead-like element can also be provided at other locations of the base element, in particular also on an inner region of the spout. Furthermore, it may also be arranged at different height positions of the spout, wherein it is preferably arranged at an upper position or even at the upper edge of the spout.

The bead-like element can be arranged in a particular embodiment over the entire circumference of the spout. But it is also possible that the bead-like element extends only over partial angular ranges of the spout, but preferably not less than 90 degrees or at least not less than 45 degrees of the circumference. It is also possible that a plurality of individual bead-like elements are provided, which are at least in extend some areas of the circumference of the spout. In this case, the individual elements can also extend over substantially small partial angle ranges, for example 10 ° to 5 °, or even substantially point-shaped.

According to another aspect of the present invention it is provided that the cover comprises a sealing or guiding element which is positioned in the fully closed position of the lid at least partially around the spout or in the spout, said sealing or guiding element preferably at least one Includes stop element.

This stop element can be realized as a locking element, as a bead, as a barb or in various different embodiments. This is preferably an at least partially elastic element.

When providing a stop element or a similar element both on the cover and on the base element, it is sufficient that only one of the elements is at least partially elastic. In a preferred embodiment, however, both elements are at least partially elastic.

In a preferred embodiment, the cover comprises a sealing element which protrudes into the opening of the spout in the closed position of the lid or engages in this and thus interacts with the spout, so that the discharge opening is sealingly closed.

It is preferably provided that at least one recess is provided on the outside of such a sealing element, which acts as a degassing channel. In this case, this acting as a degassing passage recess is formed so that it does not interact in the fully closed position of the lid with the associated element, in particular a seal, in the intermediate position, however, areas acting as a degassing recess in the region of the associated, sealing elements of the spout or the base element, so that a pressure compensation is possible. The at least one recess may be formed in one embodiment so that the wall thickness or material thickness of the sealing element is only reduced, in another embodiment, however, it is also possible that actually a limited portion of the sealing element is completely excluded, therefore, for example, a slot or similar arises in the sealing element. It should be noted at this point that in one embodiment, all elements are formed so that in the intermediate position of the lid is already an open degassing. In another embodiment, however, it is possible that corresponding sealing elements still abut each other, but these are designed so that the degassing is automatically opened even at a relatively low, differential pressure to be fixed.

A degassing in the context of this invention must meet no special geometric requirements, it must only be ensured that a pressure equalization between the container interior facing side of the closure and the environment is made possible, at least when the pressure difference between the container interior and the environment exceeds a certain value ,

In one embodiment, only one recess acting as a degassing channel is provided. In a preferred embodiment, however, a plurality of recesses, in particular for example three recesses, are provided.

The provision of a plurality of recesses, which can act in parallel, ensures that in a shorter time a larger pressure difference can be reduced, while ensuring that the product in the container does not escape. In particular, this allows lower flow rates and higher potential flow within the degassing channel, which also enhances the above-mentioned effect.

In a particular embodiment, the cover comprises on its inside at least one web on which a stop element is formed or which itself serves as a stop element, said web either itself may be formed as an elastic element or comprises an elastic element.

In a particularly preferred embodiment, the closure device comprises a hinged lid, which can be attached by means of at least one hinge to the base member, so that it can be pivoted by means of a pivoting movement from the fully closed position on the defined intermediate position in a fully open position.

In a particularly preferred embodiment, the closure device is designed so that the defined intermediate position is achieved after a pivoting of the lid of about 5 degrees to 20 degrees, preferably from about 5 degrees to 15 degrees and in particular at a pivoting of about 10 degrees. This leads to a particularly flexible and comfortable operation of the system for the user. Furthermore, the corresponding elements and parts of the closure device can be particularly well exploited at these angles, so that the production of the closure device is inexpensive, furthermore, the entire system works very reliable.

In a particularly preferred embodiment with a hinged lid, the stop device or the stop elements are arranged substantially on a side opposite to the hinge. This also serves a comfortable and safe execution of the closure device, which is structurally simple and inexpensive to manufacture, which is particularly important in such mass products of great importance.

However, the closure device according to the invention is not limited to hinged lid, although this represents a preferred embodiment, but is also possible to provide so-called "plug caps", which are not withdrawn in a pivoting movement, but substantially linearly from the base member. It is also possible to provide a cover which can be fixed by means of a screw or rotary movement on the base element.

In the case of a lid, which can be pulled off substantially linearly upward from the base element, corresponding interacting elements, in particular stop elements, are provided at least at two, in particular opposite positions in the circumferential direction, in a particularly preferred embodiment even at three or more positions , which are preferably arranged distributed substantially uniformly around the circumference. This ensures that the lid is moved automatically and evenly with respect to the circumferential direction from the fully closed position to the intermediate position.

Fig. 1A schematically shows a first embodiment of a closure device according to the invention in a cross-sectional view. The closure device comprises a base member 100 and a lid 200 which is formed as a hinged lid, wherein it is attached via a hinge device 260 to the base member 100 and to this from a fully closed position, as shown in FIG Fig. 1A is shown, about an intermediate position, see Fig. 1B in a fully open position, see Fig. 1C , can be pivoted.

The base member 100 is formed substantially cylindrical and can be placed on an opening of a container, in particular a bottle, with an internal thread 102 is provided for screwing onto a complementary external thread of a container.

In the base member 100, a spout 140 is used, which is formed substantially dome-shaped and provides a dispensing opening 160 for dispensing a product contained in the container, in particular a flowable medium, is available. Base member and spout may also be integrally formed.

The hinged lid 200 comprises a sealing element 220, which is essentially a cylindrical web formed on the inside of the lid 200, wherein this in the in Fig. 1A shown fully closed position of the lid 200 in the discharge opening 160 of the spout 140 protrudes.

The spout 140 includes on its inside sealing lips 142 which interact in the closed position of the lid with the sealing element 220 of the lid and the discharge opening 160 completely seal.

The spout 140 includes at its outer, upper edge an annular bead 144 which serves as a stop element, while the lid has a substantially circular segment-shaped bead 244 which is arranged on a centering ring 240 which is also formed in a circular segment. The interaction between the bead 144 on the spout 140 and the bead 244 on the centering device 244 is particularly in Fig. 1B visible, which is described below.

Fig. 1B shows the in Fig. 1A shown embodiment of the closure device according to the invention, wherein there is the lid 200 in the defined intermediate position. In this intermediate position, in which the lid 200 has been pivoted about 10 degrees from its fully closed position, the bead 244 of the lid 200 abuts the bead 144 of the spout 140, so that an increased force is required to the two interacting Bead elements 144, 244 move past each other. As well as in Fig. 1B and in particular in the enlarged view in FIG Fig. 1D it can be seen, the lid 200 is pivoted in the defined intermediate position so that the sealing lip 142 is located in the region of a recess 222 in the sealing element 220, so that a degassing is opened. In this position, therefore, an optionally existing overpressure between the sealing lip 142 and the sealing element 220, namely through the serving as a degassing passage 222, escape, while leakage of the product located in the container is still avoided.

Fig. 1C shows the in Fig. 1A and in Fig. 1B illustrated embodiment, in which, however, the lid is in a fully open position. The lid was at the in Fig. 1C shown pivoted position about 180 degrees. However, a fully open position already exists at lower pivoting angles. As in Fig. 1C As can be seen, the discharge opening 160 is now completely open, so that a delivery of a product is made possible.

Fig. 1E shows a plan view Fig. 1C from above, wherein here very clearly the discharge opening 160 can be seen, surrounded by a spout 140 and formed by this is, is, on the outside of which the annular bead 144 is provided. The lid 200 is connected to the base member 100 via the highly visible hinge 260.

Fig. 1E Also clearly shows the in the lid 200 located cylindrical sealing member 220 which extends from an upper wall of the lid 200, wherein in the sealing member 220 a total of three recesses 222 are provided which serve as Entgasungskanäle.

Further shows Fig. 1E very clearly the centering element 240, which is circular segment-shaped or forms a partial cylinder and has on its inside a bead 244, which interacts with the bead 144 on the outside of the spout 140 of the base member 100 in the defined intermediate position, as described above.

The centering device or the centering tube 240, which is formed in the manner of a cylinder segment, is stabilized by three webs 242 on the cover 100, wherein the webs 242 are intentionally arranged on a side substantially opposite the hinge, since in this region a particularly clear interaction of the bead 244 takes place with the bead 144.

As in the Figs. 1A, 1B and 1C it can be seen, the closure device according to the invention comprises a tamper-evident tape 120, as for example in the German patent application with the Anmeldeaktenzeichen DE 10 2006 011 445.0 , also filed by the assignee of this application.

The Fig. 2A to 2E show, in comparable representations, a second embodiment of a closure device according to the invention, which substantially in the Fig. 1A to 1E shown closure device corresponds. The same and similar elements have therefore been provided with identical reference numerals. Further, reference is made to the above description to avoid repetition.

In the Fig. 2 The second embodiment shown comprises a web element 246 which extends from an upper edge of the cover 200 and in its inner region, wherein the web element 246 comprises a bead-shaped elevation 244 which, similar to the first embodiment, with the annular bead 144 provided in the outer portion of the spout 140, the annular bead 144 being formed as in the first embodiment.

In Fig. 2B showing the lid in an intermediate position, the interaction of the bead 144 of the spout 140 and the bead 244 of the stem member 246 becomes particularly clear: The ridge member 246 is adapted to be resiliently urged substantially radially outward, but with a butt increased force is required, so that the defined intermediate position automatically detected for the user or automatically "effective" during the opening process.

Fig. 2E shows very clearly that the second embodiment has a total of three webs 246, which are arranged at positions which are opposite to the hinge 260 substantially radially, wherein the webs 246 are arranged at an angular distance of approximately 30 degrees to each other.

The Figs. 3A to 3E show, in comparable representations, a third embodiment of a closure device according to the invention, which substantially in the Fig. 1A to 1E shown closure device corresponds. The same and similar elements have therefore been provided with identical reference numerals. Further, reference is made to the above description to avoid repetition.

In the Fig. 3 illustrated third embodiment corresponds substantially to the first embodiment, wherein instead of the bead provided there (244, see Fig. 1A ) an extension member 244 is provided, which serves as a kind of barb and which interacts with the arranged on the spout 140 bead 144 in a similar manner, as in connection with the Fig. 1 and 2 has been described.

Fig. 3D shows in an enlarged view the area of the spout in the intermediate position. It is very clearly visible here how the extension element 244 interacts with the bead 144 on the spout, while still the sealing lip 142 cooperates with a portion of the sealing element 220 to ensure that no product leaks. Fig. 3D shows here a portion of the sealing element 220, which is not provided with a recess 222, while Fig. 3E on the other hand shows an area where one of the three Recesses 222 is present, so that in the intermediate position shown, a pressure equalization via the degassing is possible.

The FIGS. 4A to 4E show, in comparable representations, a fourth embodiment of a closure device according to the invention, which substantially the in FIG. 2 shown closure device corresponds. The same and similar elements have therefore been provided with identical reference numerals. Further, reference is made to the above description to avoid repetition.

In the FIG. 4 In contrast to all the preceding embodiments, the embodiment shown has a cover 200 designed as a plug-in cap, which is seen from its fully closed position Fig. 4A in his open position, see Fig. 4C is not pivoted, but is pulled off substantially linearly upward, wherein the defined intermediate position in FIG. 4B is shown.

This embodiment also includes, as in Fig. 4A can be seen, a base member 100 having a spout 140, the sealing elements 142 has on its upper inner side. The lid 200 is provided with a web 246 having a bead-like elevation 244, which interacts with a substantially annular bead 144 provided at the upper end of the outside of the spout 140, as in particular Fig. 4B is apparent.

FIG. 4B shows the in FIG. 4A illustrated embodiment, wherein the cap formed as a cover 200 is in the defined intermediate position in which the bead 244, which is provided on the lid, with the bead 144 which is provided on the spout 140 interacts, wherein the bead 244 at the bead 144 abuts, so that the defined intermediate position is reached.

Only by an increased application of force or a slight displacement of the direction of movement, it is possible that in FIG. 4B shown defined intermediate position to overcome the lid 200 in his in FIG. 4C shown completely open position in which the lid 200 is completely separated from the base member 100.

Figure 4D shows an enlarged view of the fourth embodiment in the in Fig. 4A shown position, ie in the position in which the lid is fully closed, wherein Fig. 4D clearly shows that the bead 244 of the web 246 does not interact with the bead 144 of the spout 140.

Figure 4E shows an enlarged view Fig. 4B , wherein the lid 200 is in the defined intermediate position. The bead 244 of the web 246 abuts the bead 144 of the spout 140 and defines the intermediate position, which, as described above, can be overcome only with increased force or another direction of movement.

Fig. 4E clearly shows the recess 222 in the sealing element 220, so that between the sealing lip 142 and sealing element 220, a degassing is defined, which allows pressure equalization.

The features of the invention disclosed in the foregoing description, in the drawing and in the claims may be essential both individually and in any combination for the realization of the invention in its various embodiments.
