    专利说明:

    The invention relates to a closure for a container, preferably for a bottle for drinks or the like, comprising a provided with a collar with internal thread first part.
    Especially in the packaging of drinks or the like, the shelf life after bottling is always an issue. In general, ready-mixed beverages have reduced shelf life over separate storage of water and a concentrate to be mixed, be it a powder or a liquid concentrate. In principle, it is possible to directly sell powders or concentrates, such as effervescent tablets or fruit syrups, but these must then be added by the end customer with the right amount of solvent, whereby the convenience of the application is reduced. In a device for separate storage within a container and a corresponding mixing device, the prior art shows several solutions, which, however, are all significantly more expensive to produce than the filling of already mixed drinks. On the one hand, this is due to the complex design of the storage and mixing containers and, on the other hand, to the fact that conventional filling systems are generally incompatible with these constructions.
    For example, US 6045254 shows a container which divides the container into two compartments by means of a special collar in cooperation with an axially displaceable sealing ring. It can then be stored separately liquid and concentrate. When screwing on the single thread at the container outlet, the plunger is raised and mixing between the concentrate and the liquid occurs. This construction is complex because a special bottle with a special closure must be made. The thread on the neck of the bottle must also be provided with a special end stop to prevent the user from completely unscrewing the stamp before completing the mixing process. The bottling plant must also be equipped accordingly so that this type of container can be filled at all. Overall, this increases the manufacturing costs such that it becomes uneconomical for most applications to use this type of container in practice.
    DE 69905185 T2 shows a bottle closure with a mixing device which can introduce an additive into a liquid within the bottle. The structure is generally complicated and requires different materials for the bottle closure, as to trigger the mixing process, a membrane must be pierced. The closure with the filled addition can also be made in this design only with high production costs, which makes the application in practice uneconomical.
    WO 2007/006414 A1 and US 2631521 each show embodiments in which the triggering mechanism is formed by a flexible membrane and, when pressure is applied to the membrane, a further membrane is punctured or severed in the interior of the container. Again, the manufacturing cost is large due to the different materials for the closure.
    Object of the present invention is therefore to provide a closure which is simple, easy to fill and can be used in conventional filling systems during final assembly with a container. The closure should ideally consist of a few parts, all of which can be made of one material type. In the closure, a pressure-tight chamber for receiving at least one concentrate in liquid form or in the form of a powder is to be formed.
    This object is achieved by the present invention in that on the first part an upwardly open and downwardly closed first cylindrical sleeve is formed, in which a closed top and bottom open second cylindrical sleeve is mounted axially displaceable, wherein in the first Sleeve are provided at the lower closed end openings, which are sealed at fully inserted second sleeve by the edge at the open end of the second sleeve, whereby a pressure-tight chamber for receiving a liquid and / or a powder and optionally a blowing agent is formed, and that on the upper closed end of the second sleeve, an external thread is provided, which is in engagement with an internal thread of a cover part, wherein the cover part is held by means of latching projections on the collar of the first part and rotatably supported relative thereto. The closure can thus be produced in a simple manner, for example by means of injection molding. It consists of only 3 parts, which can be made of the same material and are easy and automated zusammenfügbar. The concentrate can be filled into the resulting chamber between the first sleeve and second sleeve and the composite closure with concentrate is then used as well as a conventional bottle cap in a bottling plant, with little or no modifications to the filling system are necessary.
    It is a further feature of the invention that the threads on the cover part and on the second sleeve run counter to the thread on the collar of the first part. In a conventional bottle cap, this is turned on counterclockwise rotation. This normally corresponds to the running direction of the thread on the collar of the first part, which is screwed onto a container, for example a conventional bottle. If now the cover part of the closure according to the invention is rotated in the counterclockwise direction of rotation, the counter-rotating thread between the cover part and the second sleeve causes the second sleeve to be raised, thereby releasing the openings at the closed lower end of the first sleeve and the pressurized concentrate can escape into the bottle interior. This results in a mixing of the liquid in the container and the concentrate.
    Once the sleeve is completely screwed into the cover part this comes to an end stop. If you now continue to turn the closure in the direction of rotation, so the entire closure would be unscrewed from the container, if desired by the user.
    According to a further feature of the invention, it is provided that in the cover part a central outlet opening is provided, which is sealed in the closed starting position by a closing plug at the closed end of the second sleeve, and that passage openings on the outside of the second sleeve and on the collar of the first part are provided, through which in the open end position of the closure, a communicating connection between the interior of the container and the open in this position central outlet opening in the lid part is formed. By this measure, a drinking opening can be formed on the closure. Passage openings on the collar of the first part and on the outside of the second sleeve together with the central outlet opening in the cover part form a path to the interior of the container, through which the ready-mixed liquid can escape.
    In one possible embodiment of the invention, it is provided that at least one partition wall is arranged in the interior of the first sleeve or the second sleeve, whereby a subdivision of the chamber for receiving different substances is formed. By this measure, several different substances can be stored separately in the closure, which depending on the application, the durability of the substances within the packaging can further increase.
    It is another feature of the present invention that the frictional resistance between the thread on the second sleeve and the thread in the cover part is less than the frictional resistance between the thread on the collar of the first part and a corresponding thread on the opening of the container. This ensures that upon rotation of the closure in the Aufdrehrichtung, ie normally counterclockwise, always first the second sleeve is moved towards the open position and only after reaching the end stop of the second sleeve, the entire closure can be unscrewed from the container.
    In addition, it is a feature of the invention that at the first part above the first cylindrical sleeve along the inner periphery of the first part a plurality of vertical guide grooves are arranged, in which corresponding guide projections, which are arranged on the outside at the upper closed end of the second cylindrical sleeve, out are, whereby the second cylindrical sleeve during movement between the closed starting position and the open end position relative to the first part rotatably mounted axially displaceable. This provides a simple way to ensure that the second cylindrical sleeve is constrained within the first part and does not rotate with it during rotation of the cover part.
    Finally, it is a feature of the invention that the vertical guide grooves have at their upper open end inlet slopes, which serve in the assembly of the closure of the centering of the guide projections of the second cylindrical sleeve in the guide grooves. Thus, in an automatic assembly of the closure can always be ensured that align with the insertion of the second cylindrical sleeve in the first part of the guide projections always correct to the guide grooves. It can additionally be provided on the guide projections opposite centering bevels. It will be understood by one of ordinary skill in the art that, of course, the guide projections on the inner periphery of the first part and the guide grooves on the outer side of the second cylindrical sleeve may be arranged.
    The invention will now be described in more detail with reference to an embodiment shown in the accompanying drawings, wherein
    1 shows a sectional view through a closure according to the invention in the open end position,
    FIG. 2 shows a sectional view through the closure of FIG. 1 in the closed starting position, FIG.
    3 shows a sectional view through a first part,
    4 shows a perspective view of a first part, FIG. 5 shows a side view of a second cylindrical sleeve,
    Fig. 6 is a sectional view through the second cylindrical sleeve on Fig. 5 shows and
    Fig. 7 shows a sectional view through a cover part.
    The closure shown in FIG. 1 has a first part 3 which essentially comprises a collar 1 with an internal thread 2 and a first cylindrical sleeve 4 integrally formed on the collar 1. The first cylindrical sleeve 4 has an upper open end and a lower closed end 6, wherein at the lower closed end 6 a plurality of openings 7 are provided. In the first cylindrical sleeve 4, a second cylindrical sleeve 5 is arranged axially displaceable. The second cylindrical sleeve has an upper closed end 10 and a lower open end. Through the two telescoped sleeves 4.5 a chamber 9 is formed. In Fig. 1, the closure is shown in the open end position. However, when the closure is in the closed position, as in Fig. 2, the openings 7 are sealed at the lower closed end 6 of the first cylindrical sleeve 4 by the edge 8 at the open end of the second cylindrical sleeve 5 and the chamber 9 is pressure-tight and may contain a concentrate and / or propellant.
    The second cylindrical sleeve 5 is axially moved within the first cylindrical sleeve by rotation of the cover part 13. For this purpose, an external thread 11 engages the upper closed end 10 of the second cylindrical sleeve 5 in a corresponding internal thread 12 on the cover part 13 a. The cover part is held by means of latching projections 14 on the first part 3 and is freely rotatable relative to this.
    The cover part 13 also has a central outlet opening 15, here in the form of a drinking opening. In the closed initial position of the closure, as shown in FIG. 2, this outlet opening 15 is sealed by a closing plug 16, which is integrally formed on the upper closed end 10 of the second sleeve 5. The closing plug 16 is formed in the illustrated embodiment via a plurality of connecting webs 19 on the second sleeve 5. Furthermore, there are on the outside of the second sleeve through openings 17 and the collar 1 of the first part 3 further passage openings 18, whereby at the open end position (Fig. 1) of the closure liquid from the Inne ren of the container through the passage openings 17,18 and the central Outlet opening 15 can reach the outside.
    In Fig. 3, the first part 3 of the closure is shown in a sectional view. Here, the first cylindrical sleeve 4 with the openings 7 at the lower closed end 6 and the molded collar 1 with the internal thread 2 can be clearly seen. In the collar 1 passages 18 are also provided. On the inner circumference above the open end of the first cylindrical sleeve 4 a plurality of upwardly open guide grooves 20 are provided, which serve for receiving formed on the second cylindrical sleeve 5 guide projections 21 (see Figure 5). The guide grooves 22 have at the upper open end, as can be seen in Fig. 3 and Fig. 4 are inlet slopes 22 which center the respective guide projections 21 in the direction of the guide grooves 20, which facilitates the automatic assembly of the closure.
    In the first part 3, the second cylindrical sleeve 5, which is shown in FIGS. 5 and 6, is used to fill the closure with a concentrate and / or propellant. With the edge 8 at the open end of the second sleeve 5 seals this, the openings 7 of the first sleeve 4, whereby the pressure-tight chamber 9 is formed. At the upper closed end 10 of the second sleeve 5 are located at the outer edge passage openings 17, an external thread 11, the guide projections 21 and a connecting webs 19 integrally formed closing stopper 16th
    Finally, FIG. 7 shows the cover part 13, which is provided with an internal thread 12 which can receive the external thread 11 of the second sleeve 5. Further, located at the upper end of the cover part 13 has a central outlet opening 15 and at the lower edge of the lid part latching projections 14, by means of which the cover part 13 is held on the collar 1 of the first part 3.
