Description

Technical Field

[0001] The utility model relates to the field of anti-counterfeiting bottle caps, in particular to an anti-counterfeiting bottle cap that is scratched immediately when opened. Background Art

[0002] In order to maintain the market order and protect the rights and interests of consumers, domestic white spirits will set corresponding anti-counterfeiting measures on the bottle caps to identify the authenticity of the white spirits. At present, the anti-counterfeiting of liquor products mainly focuses on the bottle caps, that is, anti-counterfeiting teeth made of plastic structures are set. After the bottle cap is opened, the anti-counterfeiting teeth are broken. Whether there are anti-counterfeiting teeth on the bottle cap is used to judge whether it has been opened, so as to identify whether the newly bought white spirit is genuine. When opening the bottle cap, although it plays a role of destroying the bottle and the cap, after sticking the anti-counterfeiting teeth back, the bottle cap is restored. Although there will be certain differences from the original structure as a whole, it is difficult for laymen to find the authenticity without careful comparison. For this reason, we have designed an anti-counterfeiting bottle cap that is scratched immediately when opened. Content of the Utility Model

[0003] To solve the technical problem that the anti-counterfeiting mark can be restored, the utility model provides an anti-counterfeiting bottle cap that is scratched immediately when opened.

A plastic part is arranged above the inner part of the bottle mouth, and the lower end of the plastic part abuts against the upper part of the bottle mouth. A plurality of downward pressure chutes distributed in a ring shape are arranged on the outer ring surface of the plastic part. The upper end of the downward pressure chute penetrates through the upper part of the plastic part and communicates with the outside. A white cap is installed above the bottle mouth. A plurality of downward pressure parts distributed in a ring shape are arranged at the top end inside the white cap. A sharp head is further arranged on the inner side of the downward pressure part, and the sharp head extends into the downward pressure chute.

[0005] As a further improvement of the above solution, an abutting ring distributed in a ring shape is arranged inside the bottle mouth. The cross section of the plastic part is in a convex shape structure. The outer ring of the plastic part is pressed between the lower part of the abutting ring and the upper part of the inner plug. When installing the plastic part, first place the plastic part inside the bottle mouth and make the outer ring of the plastic part contact with the lower part of the abutting ring, and then place the inner plug inside the bottle mouth to fix the plastic part.

[0006] As a further improvement of the above solution, three positioning protrusions distributed in a ring shape are arranged at the top end inside the white cap. Three positioning grooves corresponding to the positioning protrusions are arranged at the lower end of the plastic part. The positioning protrusions are placed in the positioning grooves, which is convenient for installing the plastic part and enables the sharp head to be placed in the downward pressure chute.

[0007] As a further improvement of the above solution, a butt joint boss with a convex - shaped structure is arranged inside the bottle mouth, and a plurality of uniformly distributed positioning grooves are formed in the butt joint boss;

[0008] A butt joint part is arranged at the middle of the outer ring of the inner plug. A plurality of uniformly distributed positioning columns are arranged above the butt joint part. The positioning columns are inserted into the positioning grooves, and an interference fit is formed between the two. The butt joint part contacts the butt joint boss. The inner plug extends into the bottle mouth from bottom to top, and the butt joint part contacts the butt joint boss, so that the positioning columns can be inserted into the positioning grooves, thereby fixing the inner plug and the bottle mouth.

[0009] As a further improvement of the above solution, three layers of equally - spaced sealing rings are arranged on the outer - ring surface of the inner plug, and a groove is designed below the butt joint part of the inner plug. The inner plug can be placed inside the bottle mouth of the wine bottle, while the butt joint part is placed above the bottle mouth. After the bottle mouth is installed outside the bottle mouth, the butt joint part can be tightly pressed on the bottle mouth, thereby achieving sealing and improving the sealing effect;

[0010] The inner plug is designed with an upper - and - lower communication inside, and a blocking part is further arranged above the inner plug. The blocking part is used for sealing the top of the inner plug, so that part of the liquor in the wine bottle leaks. When in use, it can be directly pulled out, thus facilitating pouring of the wine.

[0011] As a further improvement of the above solution, an external spiral part is arranged above the outer - ring surface of the bottle mouth, and an internal spiral part is arranged on the inner wall of the white cap. The white cap is screwed and connected with the bottle mouth in a threaded manner, and a break - off connection point is also arranged at the connection part between the two.

A plurality of annularly distributed pressing parts 21 are arranged at the top end inside the white cap 2. A sharp head 22 is further arranged on the inner side of the pressing part 21, and the sharp head 22 extends into the pressing chute 31.

[0024] A contact ring 12 is arranged in a ring shape inside the bottle mouth 1. The cross-section of the plastic part 3 is in a convex shape. The outer ring of the plastic part 3 is pressed between the lower part of the contact ring 12 and the upper part of the inner plug 4. When installing the plastic part 3, first place the plastic part 3 inside the bottle mouth 1 and make the outer ring of the plastic part 3 contact with the lower part of the contact ring 12, and then place the inner plug 4 inside the bottle mouth 1 to fix the plastic part 3.

[0025] Three annularly distributed positioning protrusions are arranged at the top end inside the white cap 2. Three positioning grooves corresponding to the positioning protrusions are arranged at the lower end of the plastic part 3. The positioning protrusions are placed in the positioning grooves, which is convenient for installing the plastic part 3 and enables the sharp head 22 to be placed in the pressing chute 31.

[0026] Inside the bottle mouth 1, there is an abutting boss 13 with a convex shape structure, and a plurality of uniformly distributed positioning grooves are provided on the abutting boss 13. In the middle of the outer ring of the inner plug 4, there is an abutting portion 41. Above the abutting portion 41, there are a plurality of uniformly distributed positioning posts. The positioning posts are inserted into the positioning grooves, and there is an interference fit between the two. The abutting portion 41 contacts the abutting boss 13. The inner plug 4 extends into the bottle mouth 1 from bottom to top, and the abutting portion 41 contacts the abutting boss 13, and the positioning posts can be inserted into the positioning grooves, so that the inner plug 4 can be fixed to the bottle mouth 1.

[0027] On the outer ring surface of the inner plug 4, there are three layers of sealing rings 42 distributed at equal intervals, and there is a groove design below the abutting portion 41 of the inner plug 4. The inner plug 4 can be placed inside the bottle mouth of the wine bottle, while the abutting portion 41 is placed above the bottle mouth. After the bottle mouth 1 is installed outside the bottle mouth, the abutting portion 41 can be tightly pressed on the bottle mouth, thereby achieving sealing and improving the sealing effect;

[0028] The inner plug 4 is designed with an upper and lower communication inside, and a blocking portion 43 is further provided above the inner plug 4. The blocking portion 43 is used to seal the top of the inner plug 4, so that part of the liquor in the wine bottle leaks. When in use, it can be directly pulled out, so as to facilitate pouring wine.

[0029] Above the outer ring surface of the bottle mouth 1, there is an external thread portion 11, and the inner wall of the white cap 2 is provided with an internal thread portion 23. The white cap 2 is screwed to the bottle mouth 1 in a threaded manner, and an easily breakable connection point is also provided at the connection between the two. The connection point between the white cap 2 and the bottle mouth 1 is formed by spot welding with a welding machine, which can connect the two and is convenient for rotation and opening.

[0030] In the embodiment of the present application, the implementation principle of an anti-counterfeiting bottle cap that can be cut as soon as it is opened is as follows: In actual use, first screw the white cap 2 onto the bottle mouth 1 and fix the two through the easily breakable connection point. Then place the plastic part 3 inside the bottle mouth 1. During the installation process, make the positioning protrusion correspond to the positioning groove, so that the sharp head 22 can be placed in the downward pressing chute 31 during the moving installation process of the plastic part 3, and the outer ring of the plastic part 3 contacts the lower part of the abutting ring 12. Then place the inner plug 4 into the bottle mouth 1. The inner plug 4 extends into the bottle mouth 1 from bottom to top, and the abutting portion 41 contacts the abutting boss 13, and the positioning posts can be inserted into the positioning grooves, so that the inner plug 4 can be fixed to the bottle mouth 1. At this time, the plastic part 3 will be pressed between the abutting ring 12 and the upper part of the inner plug 4, so that the plastic part 3 can be fixed. At this time, the complete anti-counterfeiting bottle cap is assembled and completed;

[0031] When the white cap 2 is opened, rotate the white cap 2. The rotation of the white cap 2 will cause the internal pressing part 21 and the sharp head 22 to rotate synchronously. The rotation of the sharp head 22 will leave spiral scratches on the surface of the plastic part 3. After opening the cap, the authenticity can be identified by the scratches left on the surface of the plastic part 3. If there is one scratch, it is a genuine product; multiple messy scratches can be judged as counterfeit products with OEM labels.

[0032] By providing a pressing part 21 and a sharp head 22 on the inner wall of the white cap 2, the sharp head 22 can be placed in the pressing chute 31 of the plastic part 3. When the white cap 2 is opened, corresponding scratches will be generated. Moreover, when the white cap 2 is screwed on again, it cannot be guaranteed that it is screwed on along the original route, so that multiple messy scratches will be left on the surface of the plastic part 3, and these scratches cannot be erased, thus enabling anti-counterfeiting.

[0033] The cap first installs the white cap 2, and then sequentially sleeved with the plastic part 3 and the inner plug 4, ensuring that there are no scratches left on the surface of the plastic during the initial installation, thus facilitating subsequent judgment.

[0034] The above embodiments are only the preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantive changes and substitutions made by those skilled in the art based on the present invention fall within the scope of protection required by the present invention.
