Description

Technical Field

[0001] The utility model relates to the technical field of bottle caps, in particular to a double-destroyed flap anti-pulling and anti-counterfeiting bottle cap. Background Art

[0002] Bottle caps are an important part of food and beverage packaging, and are also the first place where consumers come into contact with products. Bottle caps have the function of keeping the contents of the product sealed, and also have the functions of anti-theft opening and safety. Therefore, they are widely used in bottled products. Therefore, bottle caps are the upstream industries of food, beverage, wine, chemical industry, and pharmaceutical industry, and are key products of bottle container packaging.

[0003] The bottle cap in the prior art only achieves the purpose of anti-counterfeiting by causing irreversible damage on the broken flap when pulling (such as the patent with publication number CN221215299U); however, if the broken flap is avoided (the broken flap is softened by heating and then pulled away from the broken groove), the bottle cap can still be separated from the bottle mouth without damage, and the anti-pullout and anti-counterfeiting effects are insufficient; at the same time, since there is only one broken flap, the broken flap has a large deformation space when pulling the bottle cap, and is not easy to break under the action of external force, resulting in a reduced anti-pulling effect of the broken flap. Utility Model Content

[0004] The purpose of the utility model is to overcome the shortcomings of the prior art and provide a double-destroyed flap anti-pullout anti-counterfeiting bottle cap. When the upper cover is pulled by force, it is destroyed at the thinning groove, resulting in the bottle cap being unable to recover after being pulled by force. It can intuitively reflect that the bottle cap is pulled open, so as to avoid the QR code or redemption code in the inner cover being restored after being pulled and scanned.

[0005] The purpose of this utility model is achieved through the following technical solutions:

[0006] A double-destruction flap anti-pullout anti-counterfeiting bottle cap comprises an upper cover, a lower cover and an inner cover, wherein the inner cover is buckled with the upper cover, the upper cover is provided with a thinning groove, and the tensile strength at the thinning groove is less than the tensile strength at the buckling point between the inner cover and the upper cover.

[0007] Furthermore, the cross-section of the thinning groove is in an inverted V shape, an inverted U shape or an inverted C shape.

[0008] Further, the upper cover comprises a cover body and a weakening portion, the weakening portion is buckled with the cover body, the inner cover is arranged in the weakening portion, and the inner cover is buckled with the weakening portion;

[0009] The thinning groove is arranged on the weakening part, and the tensile strength at the thinning groove is smaller than the strength at the buckle connection between the weakening part and the cover body, and the strength at the buckle connection between the inner cover and the weakening part.

[0010] Further, it also includes the hijab;

[0011] The cover body is provided with a buckle groove, and the cover head is arranged on the top of the cover body and buckled with the cover body through the buckle groove;

[0012] The tensile strength at the thinning groove is less than the strength at the buckle connection between the cover head and the cover body.

[0013] Furthermore, the cover is made of transparent material.

[0014] Furthermore, the thinning groove is arranged on the inner top surface of the weakening portion.

[0015] Furthermore, at least two broken petals are provided between the lower cover and the upper cover;

[0016] The destroyed flap is embedded between the upper cover and the lower cover, and when the upper cover is pulled out, the destroyed flap is torn off.

[0017] Furthermore, the destroyed flap is connected to the lower cover, the upper cover is provided with a destroyed groove adapted to the destroyed flap, and the destroyed flap is arranged in the destroyed groove;

[0018] The destroyed groove is a dovetail groove or a T-shaped groove.

[0019] Furthermore, it also includes an assembly and an inner plug, the lower cover is arranged outside the assembly, the inner cover is threadedly connected to the assembly, and the inner plug is arranged inside the assembly.

[0020] The beneficial effects of the utility model are:

[0021] 1) When the upper cover of the bottle cap of the utility model is pulled by force, it is damaged at the thinning groove, resulting in the bottle cap being unable to recover after being pulled by force, which can intuitively reflect that the bottle cap is pulled open, so as to avoid the QR code or redemption code in the inner cover being pulled and scanned and then recovered.

[0022] 2) Two sets of hook-type broken flaps are used. After the bottle cap is assembled, if the cap is pulled up by tools or under strong twisting force, the broken flap will break directly, and the broken flap cannot be restored. The visible anti-counterfeiting performance is better than the tooth-destroying and flap-destroying bottle caps on the market. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The following will be combined with the embodiments to clearly and completely describe the technical solution of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0030] See also Figure 1-Figure 5 , the utility model provides a technical solution:

[0031] Example:

[0032] like Figure 1-Figure 5 As shown, a double-destroyed flap anti-pullout anti-counterfeiting bottle cap comprises an upper cover 1, a lower cover 2 and an inner cover 3. The inner cover 3 is buckled with the upper cover 1. The upper cover 1 is provided with a thinning groove 4. The tensile strength at the thinning groove 4 is less than the tensile strength at the buckling point between the inner cover 3 and the upper cover 1.

[0033] The cross section of the thinning groove 4 is in an inverted V shape, an inverted U shape or an inverted C shape.

[0034] It also includes a component 11 and an inner plug 12 , the lower cover 2 is arranged outside the component 11 , the inner cover 3 is threadedly connected to the component 11 , and the inner plug 12 is arranged inside the component 11 .

[0035] Working principle: In this embodiment, the cross section of the thinning groove 4 is an inverted V-shape, and the tip of the thinning groove 4 is arranged upward.

[0036] Since the tensile strength at the thinning groove 4 is lower than the tensile strength at the buckle connection between the inner cover 3 and the upper cover 1 (as well as the upper cover 1 and its components and the buckle connection parts - the weakened part 6, the cover head 8, and the cover body 5 described below), when the upper cover 1 is pulled, the upper cover 1 is firstly damaged at the thinning groove 4, resulting in the bottle cap being unable to recover after being pulled by force, which can intuitively reflect that the bottle cap is pulled open.

[0037] At the same time, a QR code or a prize redemption code can be set inside the inner cover 3.

[0038] The bottle cap of the utility model is damaged at the thinning groove 4 when the upper cover 1 is pulled by force, so that the bottle cap cannot be restored after being pulled by force, which can intuitively reflect that the bottle cap is pulled open, so as to avoid the two-dimensional code or redemption code in the inner cover 3 from being restored after being pulled and scanned.

[0039] Furthermore, if Figure 1 and Figure 5 As shown, the upper cover 1 includes a cover body 5 and a weakened portion 6, the weakened portion 6 is buckled with the cover body 5, the inner cover 3 is arranged in the weakened portion 6, and the inner cover 3 is buckled with the weakened portion 6;

[0040] The thinning groove 4 is arranged on the weakened portion 6 , and the tensile strength at the thinning groove 4 is smaller than the strength at the buckle connection between the weakened portion 6 and the cover body 5 , and the strength at the buckle connection between the inner cover 3 and the weakened portion 6 .

[0041] It also includes a cover head 8; the cover head 8 is made of a transparent material (which may be but is not limited to a transparent acrylic material).

[0042] The cover body 5 is provided with a buckle groove 7, and the cover head 8 is arranged on the top of the cover body 5 and is buckled with the cover body 5 through the buckle groove 7 (buckle platform);

[0043] The tensile strength at the thinning groove 4 is less than the strength at the joint between the cover head 8 and the cover body 5 .

[0044] The thinning groove 4 is arranged on the inner top surface of the weakening portion 6 .

[0045] Thus, the cover head 8 can improve the aesthetics of the bottle cap, increase the weight of the upper cover 1, and improve the stability of the bottle cap. At the same time, the cover head 8 can hide the weakened part 6 inside, and when the upper cover 1 is pulled, the appearance of the weakened part 6 being damaged can be observed through the transparent cover head 8.

[0046] Furthermore, if Figure 1-Figure 3 As shown, at least two broken petals 9 are provided between the lower cover 2 and the upper cover 1;

[0047] The destroyed flap 9 is embedded between the upper cover 1 and the lower cover 2, and when the upper cover 1 is pulled out, the destroyed flap 9 is torn off.

[0048] The destroyed petal 9 is connected to the lower cover 2, and the upper cover 1 is provided with a destroyed groove 10 adapted to the destroyed petal 9, and the destroyed petal 9 is arranged in the destroyed groove 10;

[0049] The destroyed groove 10 is a dovetail groove or a T-shaped groove.

[0050] The bottle cap has two sets of hook-type broken flaps. After the bottle cap is assembled, if the tool is used to pull the cap up or the strong twisting force is applied, the broken flap will break directly. The broken flap cannot be restored and is a visual anti-counterfeiting feature. The two sets of broken flaps on the front and back have a small deformation space when the cap is pulled out, and are very easy to break under the action of external force. Therefore, the anti-counterfeiting performance is higher than that of the tooth-destroying and flap-destroying bottle caps on the market.

[0051] The above is only a preferred embodiment of the utility model. It should be understood that the utility model is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the concept described herein through the above teachings or the technology or knowledge of the relevant field. The changes and modifications made by those skilled in the art do not deviate from the spirit and scope of the utility model, and should be within the scope of protection of the claims attached to the utility model.
