[0001] The invention relates to the technical field of bottle caps, in particular to an anti-counterfeiting bottle cap which can be opened by destroying the top. Background Art

[0002] The top-out bottle cap is a product with relatively high consumer acceptance. Traditional wine packaging has regional restrictions, but the top-out bottle cap once became popular across the country overnight, and all wine companies, whether first-tier, second-tier, or third- and fourth-tier, have adopted it.

[0003] The advantages of top-out bottle caps over traditional bottle caps are:

[0004] 1. Compared with twist-off bottle caps, it belongs to a new category of bottle caps and has its own market position.

[0005] 2. The opening process is novel and interesting.

[0006] 3. Its anti-counterfeiting performance meets the anti-counterfeiting needs of the winery market.

[0007] 4. The cost is within the acceptable range of the winery.

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] The purpose of the present invention is to provide an anti-counterfeiting bottle cap which can be opened by destroying the top, so as to solve the problems existing in the prior art. After opening, the top of the outer cover is destroyed and cannot be repaired, so it has a high anti-counterfeiting effect and can effectively prevent counterfeit and shoddy products.

[0040] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0041] Embodiment 1

[0042] like Figure 1-5As shown, the top-destruction-opening anti-counterfeit bottle cap in this embodiment includes a bottle cap body 100, and the bottle cap body 100 includes an inner cap 2, an outer cap 1, a cover sleeve 3 and a cover inner core 4. The cover sleeve 3 is sleeved on the cover inner core 4, wherein the cover inner core 4 includes an inner core bottom 41 and a bottle head 42, the bottle head 42 is located above the inner core bottom 41, and a boss is provided on the inner core bottom 41, and the cover sleeve 3 is sleeved on the boss of the inner core bottom 41. The inner cap 2 is used to block the top opening of the cover inner core 4, the outer cap 1 is sleeved on the cover sleeve 3, and the bottle head 42 is provided with an external thread 43, and the inner side wall of the outer cap 1 is correspondingly provided with an internal thread, and the outer cap 1 is threadedly connected with the bottle head 42. An opening portion is provided on the top of the outer cap 1 of this embodiment. When the bottle cap body 100 needs to be opened, the outer cap 1 is twisted, and the cover inner core 4 moves upward relative to the outer cap 1, thereby destroying the opening portion and making the bottle head 42 extend out of the outer cap 1.

[0043] In this embodiment, when the bottle cap body 100 is opened, the top of the outer cover 1 is damaged. Since the top of the outer cover 1 is a smooth and perfect plane, a large area of ​​the ejection portion is split when it is damaged. It is completely impossible for counterfeiters to repair the gold plating or paint of the outer cover 1. The ejection portion has a large area and cannot be covered by the label, so that the outer cover 1 cannot be repaired and restored, thereby improving the anti-counterfeiting performance and effectively eliminating counterfeit and shoddy products. Moreover, when the bottle cap body 100 is opened, the entire bottle head 42 extends out of the outer cover 1. Compared with the prior art where only a gray straw is exposed, it is more beautiful and atmospheric, and has more advantages in product appearance. Among them, the bottle head 42 can adopt a traditional transparent bottle head.

[0044] In this embodiment, Figure 3-4 As shown, a direction tooth 31 is provided on the outer wall of the cover middle sleeve 3, and a latch tooth 12 cooperating with the direction tooth 31 is provided on the inner wall of the outer cover 1, and the outer cover 1 can rotate unidirectionally along the cover middle sleeve 3; specifically, the cross-sections of the direction tooth 31 and the latch tooth 12 are both triangular, and the outer cover 1 can rotate forwardly relative to the cover middle sleeve 3. When rotating in the reverse direction, the latch tooth 12 is clamped with the direction tooth 31 and cannot rotate.

[0045] In this embodiment, the outer cover 1 is rotated forwardly all the time (in this embodiment, the forward direction can be clockwise), and when opening, the outer cover 1 is twisted clockwise vigorously to make the top of the cover inner core 4 break through the top of the outer cover 1, leaking the bottle head 42 on the cover inner core 4, and then the inner cover 2 on the cover inner core 4 is opened to pour out the liquid in the bottle.

[0046] A circle of anti-skid teeth 11 is arranged on the side wall of the outer cover 1 to prevent skidding and facilitate twisting of the outer cover 1 .

[0047] In this embodiment, a V-shaped groove 5 is provided on the top inner wall of the outer cover 1 to form an opening portion. The V-shaped groove 5 is annular, and a circle is provided on the top inner wall of the outer cover 1, and is provided close to the side wall of the outer cover 1 to ensure a larger ejection portion. The wall thickness of the outer cover 1 where the V-shaped groove 5 is provided is thinner than that at other positions to form a thin-walled portion. The thickness of the thin-walled portion is 0.3-0.5 mm, wherein the V-shaped groove 5 and the outer cover 1 are integrally injection molded.

[0048] In this embodiment, the inner cover 2 is installed at the top opening of the lid core 4, and a sharp portion 6 is provided on the top of the inner cover 2 for destroying the opening portion; wherein the shape of the sharp portion 6 matches the shape of the V-shaped groove 5, and adopts a triangular structure.

[0049] In this embodiment, when the outer cover 1 is rotated, the sharp portion 6 pierces the V-shaped groove 5 to open and damage the outer cover 1. After opening, the outer cover 1 will be worn and the sharp portion 6 will be blunted without hurting the hand.

[0050] Embodiment 2

[0051] This embodiment is an improvement on the first embodiment, and the improvement is as follows:

[0052] like Figure 6 As shown, in this embodiment, the outer cover 1 and the inner cover 2 are integrally injection molded, and the V-shaped groove 5 is located at the connection between the outer cover 1 and the inner cover 2. The V-shaped groove 5 is made by die cutting technology; specifically, the outer cover 1 is placed upside down on the die base of the machine tool, the die is installed on the die base, and the die base and the die are pressed down by the telescopic arm, and the die stamps a precise V-shaped groove on the inner wall of the top of the outer cover 1.

[0053] Among them, the die cutter adopts a die cutter imported from Japan, and the PET and PP die-cutting thickness accuracy error can be controlled within 0.02-0.05mm. The number of processing times of one die cutter can reach hundreds of thousands. However, after a long injection molding time, the mold will accumulate carbon and affect the mold accuracy. Both cold mold processing and hot mold processing will affect the accuracy of the workpiece. This embodiment solves the dimensional accuracy and thickness error problems of the V-groove 5 formed by injection molding through precision die cutting, and can better control the opening quality of the outer cover 1.

[0054] In this embodiment, the wall thickness of the outer cover 1 at the V-shaped groove 5 is 0.15-0.2 mm, which is smaller. When opening, the outer cover 1 is rotated, and the bottle head 42 can easily push open the outer cover 1, so that consumers have a smoother and more fluent opening experience.

[0055] In summary, the present invention adopts the inner cover cutting opening method, or cuts out a 0.15-0.2 mm fragile thin wall with a knife die, so that the ejection is smooth and the consumer experience is better; before opening, there is no opening gap and connection point setting on the surface of the outer cover, so that the appearance of the bottle cap body is more concise and atmospheric; after opening, the entire transparent bottle head is exposed, which is more advantageous in product appearance than the prior art that only exposes a gray straw; the surface of the outer cover has no holes or gaps, does not leak dust, and the bottle cap has a high degree of hygiene and safety; and a traditional bottle head is used, so that no wine will remain in the bottle after pouring the wine; the bottle cap cannot be repaired after opening, and has high anti-counterfeiting properties.

[0056] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only used to help understand the method and core ideas of the present invention. At the same time, for those skilled in the art, according to the ideas of the present invention, there will be changes in the specific implementation methods and application scopes. In summary, the content of this specification should not be understood as limiting the present invention.
