Description

Technical Field

[0001] The utility model relates to the field of packaging containers, in particular to a bottle cap and a wine container. Background Art

[0002] At present, most of the wine bottle caps on the market are assembled into combined bottle caps with inner sleeves, inner caps and inner plugs. The materials of the internal parts of the bottle caps are mostly PC (polycarbonate) or PET (polyethylene terephthalate). According to "Table A.1" in GB4806.7-2023 "National Food Safety Standard Plastic Materials and Products for Food Contact", Item 87 stipulates that PC material shall not be used for contact with food with an ethanol content exceeding 50% (volume fraction). Therefore, the inner sleeve must be made of PET material, and the structural strength of PET material is relatively weaker than that of PC material. Therefore, the bottle cap with a PET inner sleeve can be easily pulled out from the bottle body as a whole without damaging the appearance. There is a risk of using the bottle cap again for counterfeiting after replacing the wine body.

[0003] Patent application CN117049008A discloses a bottle cap and a container bottle, whose inner sleeve adopts an integrated structure. Referring to paragraph 37 of the specific implementation method of its specification, in the case of food safety, the inner sleeve is preferably made of PET material. When pulled out by external force, the buckle on the inner sleeve can easily detach from the bottle lip of the bottle mouth; to avoid the above problem, the buckle needs to be designed as a separate metal buckle structure, and the metal buckle needs to be stamped into a predetermined shape separately, which has high processing cost. In addition, the metal buckle and the inner sleeve are split structures, and the injection molding assembly operation is relatively complicated. Utility Model Content

[0004] The purpose of the utility model is to overcome the disadvantages of the background technology and provide a bottle cap and a wine container.

[0005] The embodiments of the present invention are implemented by the following technical solutions:

[0006] On the one hand, the utility model provides a bottle cap, comprising an inner cap, an inner sleeve, an inner plug and an outer shell wrapped around the inner cap and the inner sleeve, wherein the upper end of the inner sleeve is inserted into the inner cap, and the inner plug is arranged in the inner sleeve;

[0007] The inner sleeve includes a clamping sleeve and a wine spout. The lower end of the wine spout can be inserted and pulled out of the clamping sleeve and the upper end is sealed on the inner cover. The upper end of the inner plug is sealed on the inner wall of the wine spout and a gap is left between the lower end and the inner wall of the clamping sleeve for inserting into the bottle mouth. A plurality of buckles are integrally formed on the clamping sleeve so that after the bottle mouth is inserted into the lower end of the inner sleeve, it can be clamped on the bottle lip through the plurality of buckles.

[0008] Furthermore, the plurality of buckles are evenly arranged around the axis of the ferrule.

[0009] Furthermore, a limiting groove is provided on the outer wall of the wine spout, and a limiting protrusion is provided on the inner wall of the ferrule to be clamped in the limiting groove.

[0010] Furthermore, the lower end surface of the inner cover has a flexible sealing ring / gasket, and the upper end of the wine spout is tightly sealed on the sealing ring / gasket.

[0011] Furthermore, the lower end surface of the inner cover has a group of convex ring parts, and the wine spout is sealed and connected to the convex ring parts in a socket-type manner.

[0012] Furthermore, the convex ring portion is inserted and sealed on the inner wall of the wine spout.

[0013] Furthermore, the wine spout is inserted and sealed on the inner wall of the convex ring portion.

[0014] Furthermore, the outer shell includes a first shell portion wrapped on the outer wall of the inner cover and a second shell portion wrapped on the outer wall of the ferrule, and the first shell portion and the second shell portion are connected by a plurality of twistable connecting portions.

[0015] On the other hand, the utility model also provides a wine container, including the bottle cap as described above, wherein the lower end of the inner plug is sealed and connected to the inner wall of the bottle mouth of the bottle body, and the multiple buckles are clamped on the bottle lip of the bottle body.

[0016] Furthermore, a group of retaining rings are provided on the outer wall of the inner plug, and the upper end of the bottle mouth of the bottle body abuts against the retaining rings.

[0017] The technical solution of the embodiment of the utility model has at least the following advantages and beneficial effects:

[0018] In the bottle cap of the present invention, the inner sleeve includes a detachably connected ferrule and a wine spout, and the upper end of the wine spout is sealed on the inner cap and the lower end is sealed with an inner plug arranged in the inner sleeve, so that the ferrule does not contact with the spirit; therefore, the wine spout and the ferrule can be made of different materials, that is, the wine spout in contact with the wine is made of PET material, and the ferrule can be made of PC material with higher structural strength. Therefore, the buckle integrally formed on the ferrule is also made of PC material with high strength. While ensuring the connection strength between the bottle cap and the bottle mouth, compared with the method of injection molding and assembling metal buckles on the inner sleeve, the inner sleeve of the present invention is more convenient to process and has lower cost.
