Description

Technical Field

[0001] The utility model relates to the technical field of bottle caps, in particular to a solid-liquid separation wine bottle cap. Background Art

[0002] With the improvement of living standards, people have higher and higher requirements for the quality and taste of alcoholic beverages. Since some materials used in alcoholic beverages cannot be preserved in aqueous solutions for a long time, it is necessary to place the added solid materials and the solvent separately. When drinking, put the solid materials into the solvent, shake well to make the solid materials completely dissolved in the solvent before drinking. For the convenience of use, various wine bottle caps with solid-liquid separation functions have appeared on the market; the existing solid-liquid separation bottle caps pierce the protective film that encapsulates the ingredients, so that the ingredients fall into the bottle and mix with water to form a drink. Then, when the protective film is pierced, there is a possibility that the ingredients and the protective film fall into the water at the same time, and it is not easy to distinguish the protective film from the mixed drink, which leads to the protective film being eaten, affecting human health.

[0003] A Chinese patent discloses a solid-liquid separation bottle cap (authorization announcement number CN210708692U). When the patented technology is used, the upper cover is rotated, the anti-theft strip is broken, the upper cover moves downward, the protective film approaches the puncture protrusion, the puncture protrusion cuts the protective film, and then the water bottle is inverted to allow water to flow into the storage space and mix with the ingredients. After mixing, the water bottle is straightened to allow the mixed beverage to flow back into the bottle. After repeating several times, the lower cover can be opened and immediately drunk, ensuring that the protective film will not be mixed in the water, preventing consumers from accidentally eating it, and protecting human health; however, it has certain disadvantages: like most solid-liquid separation bottle caps on the market, the first cover body and the sealing film are split, and the material needs to be placed in the first cover body first, and then the sealing film and the first cover body are fixed together by heat sealing or the like. In this process, the high-temperature harmful gas generated when the first cover body is heated will have adverse effects on the material such as pollution, and this sealing method is not reliable. After the connection between the first cover body and the sealing film is in contact with the liquid in the bottle for a long time, there will be a risk of poor sealing. Utility Model Content

[0004] The purpose of the utility model is to provide a solid-liquid separation wine bottle cap to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A solid-liquid separation wine bottle cover, comprising an upper cover and a lower cover; the upper cover comprises an upper cover body, a theft-proof ring is installed at the lower end of the upper cover body, and an inner surface of the upper cover body is provided with an internal thread, and a puncture mechanism is provided on the inner upper surface of the upper cover body; the lower cover comprises a lower cover body, an external thread is provided at the upper end position of the outer surface of the lower cover body, and an integrally formed sealing mechanism is provided at the lower end of the lower cover body, a raised portion is provided on the outer surface of the lower cover body below the external thread, a positioning pin is provided at the right end of the raised portion, and a plurality of sealing rings are installed on the outer surface of the lower cover body below the raised portion.

[0007] As a further solution of the utility model: the puncturing mechanism includes a force-bearing column, and the lower surface of the force-bearing column is provided with a beveled surface.

[0008] As a further solution of the utility model: the sealing mechanism comprises a sealing bottom, and an easy-to-break groove is provided on the upper surface of the sealing bottom.

[0009] As a further solution of the utility model: the upper end of the lower cover body is located inside the upper cover body, the puncture mechanism is located inside the lower cover body, the external thread is threadedly connected to the internal thread, the puncture mechanism is opposite to the sealing mechanism, and the anti-theft ring fits the upper surface of the raised portion.

[0010] As a further solution of the utility model: the upper end of the stress-bearing column is installed on the inner upper surface of the upper cover body, and the stress-bearing column is located inside the lower cover body, and the outer surface of the stress-bearing column fits the inner surface of the lower cover body.

[0011] As a further solution of the present invention: the sealing bottom and the lower cover body are integrally formed.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The lower cover body filled with materials and the sealing bottom are integrally injection molded, which is different from the bottle caps on the market that require materials to be placed in the bottle caps first and then thermoplastically sealed with aluminum foil. The lower cover body and the sealing bottom are integrally molded in the utility model, and materials are placed inside the lower cover body at a later stage. Therefore, the materials will not be affected by high-temperature harmful gases when the plastic is heated, and the integrally molded structure has better sealing performance, and there will be no risk of poor sealing when in contact with wine for a long time.

[0014] The positioning pin fits into the positioning groove of the wine bottle mouth, preventing the lower cover body from rotating while the upper cover body rotates; the setting of the bevel surface and the easy-to-break groove makes it easier to cut the sealed bottom, and the sealed bottom will not be cut off completely, avoiding the sealed bottom from being adjusted into the wine bottle.

[0022] The lower cover body 9 is filled with soluble materials. The part of the lower cover body 9 located below the protrusion 14 is used to insert into the inside of the wine bottle mouth. The sealing ring 16 is preferably made of rubber and polyethylene to play a sealing role; the anti-theft ring 4 itself is provided with a small gap, and there are evenly elongated holes between it and the upper cover body 3, which is convenient for pulling it off from the upper cover body 3, so that the upper cover body 3 can be rotated. The clockwise rotation of the upper cover body 3 can drive the force-bearing column 7 to cut the sealing bottom 12, and the chamfered surface 8 and the easy-to-break groove 13 are opposite to each other, so that The sealing bottom 12 can be cut more easily, and the beveled surface 8 will not cut the entire sealing bottom 12.

[0023] The working principle of the utility model is: when in use, the user pulls off the anti-theft ring 4 from the upper cover body 3, and then rotates the upper cover body 3 clockwise for a certain number of turns. The force-bearing column 7 rotates while descending, and cuts the sealing bottom 12 when it contacts the easy-to-break groove 13, so that the material in the lower cover body 9 falls into the wine bottle.

[0024] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
