Description
Technical Field
The utility model relates to the technical field of bottle cap anti-counterfeiting, in particular to a pull-out preventing structure of a lower sleeve of a thin-wall plastic cap.
Background
The bottle cap is an important ring of food and drink packages and is also the place where consumers first contact the product. The bottle cap has the function of keeping the sealing performance of the content product and also has the functions of preventing theft and opening and safety, so that the bottle cap is widely applied to bottled products, and is an upstream industry of food, beverage industry, wine, chemical industry and pharmaceutical industry, and is a key product for packaging bottle containers.
The existing bottle cap has the following defects: the bottle cap is formed by plastic injection molding, and due to the characteristics of plastic, poor vendors can uniformly draw through equipment when the bottle cap is in a high-temperature environment to enable the bottle cap to be integrally separated from a bottle opening (particularly, the latch of the assembly component is separated from the glass bottle opening to enable connection between the bottle cap and the glass bottle to fail), so that the bottle cap is arranged after the wine is replaced and counterfeited. The prior art solves this problem by providing a metal collar that engages the bottle lip, as in the patent publication CN 218199803U.
In this way, the whole bottle cap can be prevented from being pulled out, but other parts of the bottle cap (such as the upper cover, the middle cover, the inner cover and the lower sleeve are plastic parts) are not designed with a heat-pulling prevention structure, such as the middle cover and the inner cover, and when the middle cover is pulled out of the inner cover (the middle cover and the outer cover are pulled out of the inner cover), the middle cover is not limited to the lower sleeve in the axial direction. At this time, the sleeve is pulled out by heat, and the lower sleeve is easy to be pulled out directly after being softened. After the lower sleeve is pulled out, the inner cover is unscrewed, and the inner cover can still be reset when the lower sleeve is screwed again, so that the wine can be replaced without any mark; namely, the existing bottle cap still has the hidden trouble of being counterfeited.
Disclosure of Invention
The utility model aims to overcome the defects of the prior art and provide the anti-pulling structure of the lower sleeve of the thin-wall plastic cover, wherein the clamping petals and the thinning grooves are arranged, when the sleeve is pulled down by hot drawing, the clamping petals directly act on the thinning grooves, so that the lower sleeve is damaged at the thinning grooves, the effect of damaging the lower sleeve by drawing is further achieved, and the anti-pulling function of opening the bottle cover in a drawing mode can be visually reflected from the appearance.
The aim of the utility model is realized by the following technical scheme:
the bottle cap comprises a thin-wall plastic cap lower sleeve anti-pulling structure, an assembly and a lower sleeve, wherein a metal collar for being clamped with a bottle lip is arranged between the assembly and the lower sleeve; the bottom of the metal collar is provided with an everting clamping flap, and the inner wall of the lower sleeve is provided with a thinning groove;
the clamping petals extend into the thinning groove, and when the bottle cap is pulled, the clamping petals damage the lower sleeve from the thinning groove.
Further, the section of the thinning groove is concave.
Further, the section of the thinning groove is a right triangle, and the horizontal right-angle side of the thinning groove is positioned below the bottom side of the clamping flap.
Further, a guide groove is arranged in the thinning groove, and the guide groove is parallel to the horizontal right-angle side of the thinning groove.
Further, the thinning groove is an annular groove.
Further, the metal collar is made of stainless steel.
The beneficial effects of the utility model are as follows:
according to the utility model, the clamping petals and the thinning grooves are arranged, when the sleeve is pulled down by hot drawing, the clamping petals directly act on the thinning grooves, so that the lower sleeve is damaged at the thinning grooves, the effect of damaging the lower sleeve by drawing is further achieved, and the anti-counterfeiting function of opening the bottle cap in a drawing mode can be visually reflected from the appearance.

Detailed Description
The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments, and it is apparent that the described embodiments are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by a person skilled in the art without any inventive effort, are intended to be within the scope of the present utility model, based on the embodiments of the present utility model.
Referring to fig. 1-3, the present utility model provides a technical solution:
example 1:
as shown in fig. 1 and 2, a pull-out preventing structure of a lower sleeve of a thin-wall plastic cover is provided, wherein a metal collar 3 for clamping with a bottle lip is arranged between an assembly 1 and the lower sleeve 2; the bottom of the metal collar 3 is provided with an everting clamping flap 4, and the inner wall of the lower sleeve 2 is provided with a thinning groove 5;
the clamping petals 4 extend into the thinning grooves 5, and when the bottle cap is pulled, the clamping petals 4 damage the lower sleeve 2 from the thinning grooves 5.
Further, the section of the thinning groove 5 is a right triangle, and the horizontal right-angle side of the thinning groove 5 is positioned below the bottom side of the clamping flap 4.
Further, a guiding groove 6 is arranged in the thinning groove 5, and the guiding groove 6 is parallel to the horizontal right-angle side of the thinning groove 5. The horizontal cathetus of the thinning grooves 5 are parallel as shown at a in fig. 2.
Further, the thinning groove 5 is an annular groove. The thinning groove 5 is provided as an annular groove, and the lower sleeve 2 can be broken more easily when being pulled.
Further, the metal collar 3 is made of stainless steel.
In the embodiment 1, the bottom surface of the clamping flap 4 is closely attached to the bottom surface of the thinning groove 5.
Working principle: when the sleeve 2 is directly pulled down by hot drawing, the lower sleeve 2 has upward movement tendency. And because the bottom edge of the clamping flap 4 abuts against the horizontal right-angle edge of the thinning groove 5, the drawing force is concentrated on the horizontal right-angle edge of the thinning groove 5. Meanwhile, the strength of the lower sleeve 2 at the position of the thinning groove 5 is reduced due to the arrangement of the thinning groove 5, when the horizontal right-angle edge of the thinning groove 5 is stressed, the lower sleeve 2 is directly torn along the horizontal direction under the action of the guide groove 6, so that the effect of damaging the lower sleeve 2 during hot drawing is achieved, and the lower sleeve 2 cannot be restored.
According to the utility model, the clamping petals 4 and the thinning grooves 5 are arranged, when the sleeve 2 is pulled down by hot drawing, the clamping petals 4 directly act on the thinning grooves 5, so that the lower sleeve 2 is damaged at the thinning grooves 5, the effect of damaging the lower sleeve 2 by drawing is achieved, and the anti-counterfeiting function of opening the bottle cap in a drawing mode can be visually reflected from the appearance.
Example 2:
as shown in fig. 3, this embodiment is different from embodiment 1 in that the cross section of the thinned groove 5 is concave. The arrangement can reduce the material used in the lower sleeve forming process, and is beneficial to saving the cost.
The foregoing is merely a preferred embodiment of the utility model, and it is to be understood that the utility model is not limited to the form disclosed herein but is not to be construed as excluding other embodiments, but is capable of numerous other combinations, modifications and environments and is capable of modifications within the scope of the inventive concept, either as taught or as a matter of routine skill or knowledge in the relevant art. And that modifications and variations which do not depart from the spirit and scope of the utility model are intended to be within the scope of the appended claims.
