Description

Technical Field

[0001] The utility model relates to the field of anti-counterfeiting bottle caps, in particular to an anti-counterfeiting bottle cap with an explosion-proof structure. Background Art

[0002] After liquor is filled, a cork and a bottle cap are provided on it for sealing. In order to ensure the sealing performance, a layer of plastic is generally shrink-wrapped outside the bottle cap. When in use, the outer plastic is removed and the bottle cap is removed to drink. After that, the user generally screws the bottle cap on again to ensure that the liquor inside can be stored continuously.

[0003] However, after unscrewing, it may be difficult to ensure that the bottle cap is screwed on completely and in a sealed state due to certain reasons. Ethanol in liquor is a flammable substance with a flash point of 12°C. Liquor with an alcohol content of 80% has a flash point of about 19°C and also belongs to flammable substances. If there is a gap at the bottle mouth of the liquor, air inside and outside the bottle can circulate. In case of high-temperature weather, it is very likely that alcohol will volatilize, increasing the air pressure inside the bottle. When the air pressure inside the bottle reaches a certain level, an explosion will occur. For this reason, we have designed an anti-counterfeiting bottle cap with an explosion-proof structure. Content of the Utility Model

[0004] To solve the technical problem that after unscrewing, it may be difficult to ensure that the bottle cap is screwed on completely and in a sealed state due to certain reasons, which may cause alcohol volatilization, increase the air pressure inside the bottle, and an explosion will occur when the air pressure inside the bottle reaches a certain level, the utility model provides an anti-counterfeiting bottle cap with an explosion-proof structure.

[0005] The utility model is realized by adopting the following technical solutions: an anti-counterfeiting bottle cap with an explosion-proof structure, including a bottle mouth, an inner plug is plugged inside the bottle mouth, the bottle mouth is sleeved inside a neck sleeve, and the upper half of the bottle mouth is placed above the neck sleeve. The upper half of the bottle mouth is spirally installed with a white cap, and an upper cap is also provided above the neck sleeve, and the white cap extends into the upper part inside the upper cap;

[0006] A round hole is formed through the center of the white cap up and down. A sealing disc is arranged above the round hole inside. A cylinder is arranged at the lower end of the sealing disc, and the cross sections of the two are distributed in a nail structure. Six groups of broken pieces are annularly distributed at the lower outer circle of the cylinder, and the outer wall of the broken piece is connected with the inner wall of the round hole, and both sides of the broken piece are connected with the side surfaces of adjacent broken pieces.

[0007] As a further improvement of the above solution, the connection between the broken piece and adjacent broken pieces and the round hole is designed to be sealed and provided with scratches. There is no gap left at the connection between the broken piece and the broken piece and the round hole, which improves the sealing performance, and the set scratches also facilitate the fracture of the broken piece, thereby forming a gap for the discharge of internal gas, reducing the internal air pressure;

[0008] A plurality of annularly distributed air holes are provided on the upper end surface of the sealing disc. The air holes are used to discharge the internal air flow, and the design of the sealing disc avoids the direct action of external force on the lower broken pieces, preventing the broken pieces from cracking during normal use by personnel.

[0009] As a further improvement of the above solution, a sealing piece is provided above the inner part of the bottle mouth. The sealing piece is used to seal the inner part of the bottle mouth, thus ensuring the sealing effect of the wine bottle. When drinking, the sealing piece needs to be removed.

[0010] A sealing ring is provided at the top end inside the white cap. The outer wall of the sealing ring is in close contact with the inner wall of the bottle mouth, and the lower end of the sealing ring does not contact the sealing piece. The sealing ring seals the connection between the white cap and the bottle mouth, improving the sealing effect.

[0011] As a further improvement of the above solution, an abutting portion is provided on the outer circle of the inner plug, and a socket groove is formed by the depression on the lower end surface of the abutting portion. The abutting portion is sleeved on the bottle mouth of the white wine bottle, and the top end of the bottle mouth contacts the top of the socket groove. With the pressing of the bottle mouth provided, the inner plug is directly and closely attached to the bottle mouth, improving the sealing effect.

[0012] Sealing rings II and I are respectively provided above and below the outer circle surface of the inner plug. Sealing rings I and II can be in close contact with the inner wall of the bottle mouth, improving the sealing effect.

[0013] As a further improvement of the above solution, a contact protrusion is integrally formed on the outer circle surface of the neck sleeve. A security strip is provided above the contact protrusion. A docking notch is provided below the outer circle of the upper cap. The bottom end of the upper cap is above the contact protrusion. The security strip is placed in the docking notch. An easily breakable connection point is provided at the connection between the bottom end of the upper cap and the upper surface of the contact protrusion. Rotating the upper cap can cause the security strip to break, which is convenient for checking whether the bottle cap has been opened and can be used for anti-counterfeiting.

[0014] As a further improvement of the above solution, a melting and pressing portion is integrally formed at the lower end of the neck sleeve, and an annular groove is formed by the depression of the melting and pressing portion. After the neck sleeve is sleeved on the bottle mouth, a hot melt gun makes the melting and pressing portion firmly connected to the outer wall of the bottle mouth, and the inner diameter of the melting and pressing portion is reduced at this time, making it impossible to completely disassemble the neck sleeve, improving the anti-counterfeiting effect.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0016] 1. The utility model is provided with a sealing piece inside the bottle, and a sealing design is adopted between the inner plug and the bottle mouth. After the anti-counterfeiting bottle cap is sealed during packaging, there will be no gap at the mouth of the white spirit bottle, avoiding the air circulation inside and outside the bottle, preventing it from bursting. In cooperation with the breaking piece provided on the white cap, when the air pressure inside the wine bottle continuously increases, the provided breaking piece will break, thereby connecting the inside of the white cap with the outside. At this time, the pressure can be relieved in time, thus avoiding explosion.

[0017] 2. By integrally forming a pressing and melting part at the lower end of the neck sleeve, after the neck sleeve is sleeved on the bottle mouth, a hot melt gun makes the pressing and melting part firmly connected to the outer wall of the bottle mouth, and the inner diameter of the pressing and melting part decreases at this time, making it impossible to completely disassemble the neck sleeve, improving the anti-counterfeiting effect.

A white cap 3 is screwed and installed on the upper half of the bottle mouth 5. An upper cap 1 is also provided above the neck sleeve 2, and the white cap 3 extends into the upper part inside the upper cap 1;

[0030] A circular hole 32 is formed through the center of the white cap 3 up and down. Above the inside of the circular hole 32, a sealing disc 31 is provided. A cylinder is provided at the lower end of the sealing disc 31, and the cross-sections of the two are distributed in a nail structure. Six groups of broken pieces 33 are annularly distributed at the lower outer circle of the cylinder, and the outer wall of the broken piece 33 is connected to the inner wall of the circular hole 32. The two sides of the broken piece 33 are connected to the side surfaces of the adjacent broken pieces 33.

[0031] The connection between the broken piece 33 and the adjacent broken pieces 33 and the circular hole 32 is designed to be sealed, and scratches are provided. There will be no gap left at the connection between the broken piece 33 and the broken pieces 33 and the circular hole 32, which improves the sealing performance. The set scratches also facilitate the fracture of the broken piece 33, and then form a gap for the discharge of the internal gas, reducing the internal air pressure;

[0032] A plurality of annularly distributed air holes are formed on the upper end surface of the sealing disc 31. The air holes are used to discharge the internal air flow, and the design of the sealing disc 31 prevents external force from directly acting on the broken piece 33 below, avoiding the fragmentation of the broken piece 33 during the normal use by personnel.

[0033] A sealing piece 51 is provided above the inside of the bottle mouth 5. The sealing piece 51 is used to seal the inside of the bottle mouth 5, thus ensuring the sealing effect of the wine bottle. To drink, the sealing piece 51 needs to be removed;

[0034] A sealing ring is provided at the top end inside the white cap 3. The outer wall of the sealing ring is in close contact with the inner wall of the bottle mouth 5, and the lower end of the sealing ring does not contact the sealing piece 51. The sealing ring seals the connection between the white cap 3 and the bottle mouth 5, improving the sealing effect.

[0035] An abutting portion 41 is provided on the outer circle of the inner plug 4, and a socket groove is formed by the depression on the lower end surface of the abutting portion 41. The abutting portion 41 is sleeved at the bottle mouth of the white wine bottle, and the top of the bottle mouth contacts the top of the socket groove. With the pressing of the bottle mouth 5 provided, the inner plug 4 is directly and closely attached to the bottle mouth, improving the sealing effect;

[0036] A second sealing ring 43 and a first sealing ring 42 are respectively provided above and below the outer surface of the outer circle of the inner plug 4. The first sealing ring 42 and the second sealing ring 43 can be in close contact with the inner wall of the bottle mouth, improving the sealing effect.

[0037] The outer surface of the outer ring of the neck collar 2 is integrally formed with contact protrusions 23. Above the contact protrusions 23, there is an anti-counterfeiting strip 22. Below the outer ring of the upper cover 1, there is a docking notch 11. The bottom end of the upper cover 1 is above the contact protrusions 23, and the anti-counterfeiting strip 22 is placed within the docking notch 11. At the connection between the bottom end of the upper cover 1 and the upper surface of the contact protrusions 23, there is a breakable connection point. When the upper cover 1 rotates, the anti-counterfeiting strip 22 can be broken, which is convenient for checking whether the bottle cap has been opened and can be used for anti-counterfeiting.

[0038] The lower end of the neck collar 2 is integrally formed with a pressing and melting part 21, and the pressing and melting part 21 is recessed to form an annular groove. After the neck collar 2 is sleeved on the bottle mouth, a hot melt gun makes the pressing and melting part 21 firmly connected to the outer wall of the bottle mouth, and the inner diameter of the pressing and melting part 21 is reduced at this time, making it impossible to completely disassemble the neck collar 2, improving the anti-counterfeiting effect.

[0039] In the embodiment of the present application, the implementation principle of an anti-counterfeiting bottle cap with an explosion-proof structure is as follows: By providing an abutting part 41 outside the inner plug 4, the abutting part 41 can be pressed on the upper part of the bottle mouth, so that the lower end of the inner plug 4 can be firmly attached to the bottle mouth, improving the sealing performance and making it not easy to leak. Also, a sealing piece 51 is provided above the inside of the bottle mouth 5. After the anti-counterfeiting bottle cap is sealed during packaging, there will be no gap at the white spirit bottle mouth, preventing the air inside and outside the bottle from flowing, and making it not prone to explosion.

[0040] After the white spirit is opened, the sealing piece 51 is removed. At this time, the inside of the bottle mouth 5 is directly connected to the white cap 3. If the air pressure inside the wine bottle continues to increase, the set breaking piece 33 will break, making the inside of the white cap 3 communicate with the outside. At this time, the pressure can be relieved in time, thus avoiding explosion.

[0041] By providing a sealing piece 51 inside the bottle and having a sealed design between the inner plug 4 and the bottle mouth, after the anti-counterfeiting bottle cap is sealed during packaging, there will be no gap at the white spirit bottle mouth, preventing the air inside and outside the bottle from flowing, and making it not prone to explosion. In cooperation with the breaking piece 33 provided on the white cap 3, when the air pressure inside the wine bottle continues to increase, the set breaking piece 33 will break, making the inside of the white cap 3 communicate with the outside. At this time, the pressure can be relieved in time, thus avoiding explosion.

[0042] The lower end of the neck collar 2 is integrally formed with a pressing and melting part 21. After the neck collar 2 is sleeved on the bottle mouth, a hot melt gun makes the pressing and melting part 21 firmly connected to the outer wall of the bottle mouth, and the inner diameter of the pressing and melting part 21 is reduced at this time, making it impossible to completely disassemble the neck collar 2, improving the anti-counterfeiting effect.

[0043] The above embodiments are only the preferred embodiments of the present utility model, and the scope of protection of the present utility model cannot be limited thereby. Any non-substantive changes and substitutions made by those skilled in the art based on the present utility model fall within the scope of protection required by the present utility model.
