Definitions
- the invention relates to a closure cap for bottles or the like, with a screw section which has a thread for fastening the closure cap on the bottle, with a cover section for closing an opening of the bottle and with at least one chamber for receiving a content to be separated from the bottle Material, which chamber is sealed from the interior of the bottle when the cap is screwed onto the bottle.
- the object of the present invention is to develop a closure cap of the type described above in such a way that it can be used with an ordinary glass or plastic bottle and that a simple structure is achieved which enables inexpensive production.
- the chamber is arranged essentially in the form of a ring in the transition region of the screw section to the cover section and in that a locking ring is provided on the inner periphery of the cover section, which closes the chamber and is connected to the cover section via a sealing surface.
- the structure is extremely simple since, depending on the design variant, the closure cap consists of only one or two parts.
- the closure cap according to the invention can be used without any problems both for conventional glass bottles and for plastic bottles, for example made of PET. The reusability and recyclability of the bottle is not affected by parts that fall into the inside of the bottle when used as intended and may be difficult to remove from there.
- the material that is accommodated in the chamber can be powdered, in the form of granules or liquid, as required.
- the closure ring has a support surface which is supported in the opening of the bottle.
- the closure ring is held in the opening of the bottle in a frictionally locking manner via the support surface.
- the locking ring is held by the bottle in the form of a press fit and does not rotate with the cap when it is opened. This releases the chamber and the contents of the chamber can leak out and mix with the contents of the bottle.
- the locking ring can be removed from the opening after removing the locking cap remain in the bottle or be pulled off together with a corresponding projection on the closure cap.
- closure ring has a seat surface which is seated on an end surface of the opening of the bottle.
- the interior volume of the chamber in particular can be made generous.
- a further particularly preferred embodiment variant of the invention is characterized in that an annular sealing lip is formed on the cover section, which cooperates with the sealing surface of the locking ring. In this way, the pressure on the sealing surface can be kept within a favorable range, so that a good seal can always be ensured even in the event of temperature-related pressure fluctuations inside the bottle.
- the locking ring is designed as a component separate from the locking cap and is connected to it via a clamp connection.
- the clamp connection serves to prevent the closure from falling apart when the bottle is being filled and therefore only needs to exert low holding forces.
- the holding force should be less than the force with which the closure ring is held in the opening of the bottle in order to ensure that the chamber opens when the closure cap is unscrewed.
- the locking ring can be integrally connected to the locking cap. This connection can be made by thinning the material, so that easy separation is guaranteed when the bottle is opened.
- the one-piece design has the advantage of being easier to manufacture.
- the locking ring can be made from another material adapted to the material of the remaining sealing cap in a two-component injection molding process.
- a plurality of chambers can be provided in the circumferential direction, which are sealed off from one another. This enables the field of application of the closure cap according to the invention to be expanded.
- Fig. 1 shows a first embodiment of the invention in a partial section
- FIG. 2 shows a further variant in a section corresponding to FIG. 1.
- the closure cap 1 of FIG. 1 consists of a screw section 2, which is intended to engage a thread 5 in a thread 5 of a bottle 4, which is only partially shown. At the upper edge, the screw section 2 is followed by a cover section 6, which forms the actual closure of the bottle 4. In an end region of the opening 7 of the bottle 4, a closure ring 9 is inserted in a press fit via a support surface 8. The locking ring 9 is connected to the screw section 2 in a region 10 via a clamp connection.
- annular chamber 11 is formed, which is sealed off by the locking ring 9.
- the closure is brought about by a sealing lip 12 on the cover section 6, which is prestressed on a sealing surface 13 on the locking ring 9.
- the closure ring 9 is supported on a front surface 14 of the bottle opening via a seat surface 15.
- the chamber 11 in the removed cap 1 is also filled with the material to be mixed with the bottle contents.
- the chamber 11 is closed and the locking ring 9 is held in the region 10 by the clamp connection.
- the closure cap 1 can be placed on the filled bottle 4.
- the closure ring 9 is held in the opening 7 of the bottle 4 and the chamber 11 is opened in this way, so that the contents fall out and can be mixed with the contents of the bottle.
- FIG. 2 differs from that of FIG. 1 in that the locking ring 9 is integrally connected to the screw section 2 via a material thinner 16. When the bottle 4 is opened, this connection is destroyed and the chamber 11 is opened as above.
- a radial projection 17 is provided in the upper region of the locking ring 9, which is at a distance from a shoulder 18 of the screw section 2.
- the chamber 11 can be separated into several independent and separately fillable sections.
- the present invention makes it possible to present a closure cap with a very simple structure, which enables the functionality of separate storage and the automatic addition of a second medium to the bottle content with any commercially available screw-top bottle.
