The heat shrinkable cap will shrink when heated due to the characteristics of its own material. The shrunk heat shrinkable cap will wrap around the neck of the bottle and seal the bottle mouth.

[0003] In the prior art, digital information such as trademarks and anti-counterfeiting marks are printed on the heat shrinkable cap to achieve anti-counterfeiting effect. However, the heat shrinkable cap is not damaged after being pried open, and may be re-sealed on the bottle mouth by heat shrinking, so the anti-counterfeiting effect is poor. Utility Model Content

[0004] Therefore, the technical problem to be solved by the utility model is to overcome the defect of poor anti-counterfeiting effect of the heat shrinkable adhesive cap in the prior art, thereby providing a heat shrinkable adhesive cap.

[0008] Furthermore, the two opening dental flosses are arranged in parallel, or one opening dental floss and the axial end of the lining body are arranged in parallel; in the axial direction of the rubber cap body, the width of the tear strip is the same as the width of the opening handle.

[0009] Furthermore, the dental floss opening is a dotted incision or a long V-groove.

[0010] Furthermore, the material of the lining piece is an imitation gold foil plastic sheet.

[0011] Furthermore, the lining member includes a plastic film layer and an aluminum-plated layer stacked together; or the lining member includes a plastic film layer and a laser pattern layer stacked together; or the lining member includes a plastic film layer and a photonic crystal layer or a laser pattern layer or a photonic crystal layer stacked together.

[0012] Furthermore, one end of the rubber cap body connected to the rubber cap cover is provided with a main body heat-bent portion that shrinks inwards, and the rubber cap cover is a plastic film that is sealed and connected to the main body heat-bent portion.

[0013] Furthermore, an axial end of the lining body close to the rubber cap cover abuts against the hot-bent portion of the body; and an axial length of the lining body in the axial direction of the rubber cap body is smaller than an axial length of the rubber cap body.

[0014] Furthermore, the other end of the rubber cap body away from the rubber cap cover is provided with an inward folding structure bent toward the inside of the rubber cap body.

[0035] Embodiment 1

[0036] The utility model embodiment provides a heat shrinkable adhesive cap, such as Figure 1As shown in Figure 6, the heat shrinkable rubber cap includes a rubber cap body 1, a rubber cap cover 2 and a lining member 3. Among them, the rubber cap body 1 is a cylindrical structure with openings at both ends, and the rubber cap cover 2 is sealed and connected to the opening at one end of the rubber cap body 1; the lining member 3 includes a lining body 31 and an opening handle 32 connected to one end of the lining body 31, the lining body 31 is attached to the inner wall of the rubber cap body 1, and the opening handle 32 passes through the joint on the rubber cap body 1 and is exposed to the outside of the rubber cap body 1; the rubber cap body 1 is made of a transparent or translucent plastic heat shrinkable film or a transparent body or a translucent body or partially transparent, and the side of the lining body 31 facing the rubber cap body 1 is provided with a pattern or a concave-convex texture.

[0037] This heat shrinkable rubber cap is provided with a lining member 3 consisting of a lining body 31 and an opening handle 32 on the rubber cap body 1, the lining body 31 is attached to the inner wall of the rubber cap body 1, and the opening handle 32 passes through the joint on the rubber cap body 1 and is exposed to the outside of the rubber cap body 1; the pattern or concave-convex texture on the lining body 31 can be observed through the transparent or translucent rubber cap body 1, and since the pattern or concave-convex texture used for anti-counterfeiting is provided on the lining body 31 inside the rubber cap body 1, the anti-counterfeiting measures are not easily destroyed from the outside of the rubber cap body 1, thereby improving the anti-counterfeiting effect of the heat shrinkable rubber cap. Moreover, when an external force pulls the opening handle 32, the opening handle 32 will simultaneously destroy the rubber cap body 1 and the lining body 31, and the damaged heat shrinkable rubber cap cannot be restored, and the residual part of the damaged rubber cap body 1 will remain at the bottle mouth position, resulting in the inability to install a new heat shrinkable rubber cap, further improving the anti-counterfeiting effect of the heat shrinkable rubber cap. In addition, this heat shrinkable rubber cap also has the advantages of simple structure, easy manufacture, and low production cost.

[0038] like Figure 4As shown in Figure 6, the lining member 3 is made of plastic film, and the lining member 3 is a gold foil-like plastic sheet before winding. During the processing of the heat shrinkable rubber cap, the lining member 3 is first attached to the surface of the rubber cap body 1, and then wound together with the rubber cap body 1 to form a cylindrical heat shrinkable rubber cap. The lining body 31 is cylindrical after winding, and the opening handle 32 passes through the butt joint after the two ends of the rubber cap body 1 are wound. In the first implementation of this embodiment, the lining body 31 includes two circumferential ends located at opposite ends, and the lining body 31 is provided with two opening floss 33 extending from one circumferential end to the other circumferential end, and the two ends of the opening floss 33 are respectively located on the two circumferential ends; the part of the lining body 31 located between the two opening floss 33 is a tear strip 34, and the opening handle 32 is connected to one of the circumferential ends of the tear strip 34. Specifically, the two opening floss 33 are arranged in parallel; in the axial direction of the rubber cap body 1, the width of the tear strip 34 is the same as the width of the opening handle 32. When the opening handle 32 is pulled by external force, the opening handle 32 will destroy the lining body 31 along the two opening lines 33, and the tear strip 34 will be torn off from the lining itself along with the opening handle 32, so that the opening handle 32 can destroy the lining body 31 and the rubber cap body 1. Figure 7 As shown, the liner body 31 is provided with only one opening floss 33 extending from one circumferential end to the other circumferential end, the opening floss 33 is parallel to the axial end of the liner body 31, and the portion of the liner body 31 between the opening floss 33 and one of the axial ends of the liner body 31 is a tear strip 34. The end of the opening floss 33 away from the opening handle 32 does not extend to the circumferential end of the liner body 31.

[0039] Specifically, the lining member 3 is formed by laminating a plastic film layer and an aluminum-plated layer; or the lining member 3 is formed by laminating a plastic film layer and a laser pattern layer; or the lining member 3 is formed by laminating a plastic film layer and a photonic crystal layer. The opening floss 33 is a point-break cut or a long V-groove; such a configuration facilitates the breaking of the opening floss 33, and has the advantages of simple structure and low manufacturing cost.

[0040] In some embodiments, one end of the rubber cap body 1 connected to the rubber cap cover 2 is provided with a main body hot-bent portion 12 that shrinks inward, and the rubber cap cover 2 is a plastic film that is sealed and connected to the main body hot-bent portion 12. The provision of the main body hot-bent portion 12 is conducive to increasing the contact area between the rubber cap cover 2 and the rubber cap body 1, and improving the reliability of the sealing connection between the two.

[0041] In the first implementation of this embodiment, Figure 2 and Figure 6As shown, one axial end of the liner body 31 close to the rubber cap cover 2 abuts against the main body hot bending portion 12; in the axial direction of the rubber cap body 1, the axial length of the liner body 31 is less than the axial length of the rubber cap body 1. In the third implementation of this embodiment, as Figure 8 As shown, an axial end of the lining body 31 close to the main body heat bending portion 12 is arranged flush with the main body heat bending portion 12. When the heat shrinkable rubber cap shrinks, the lining body 31 and the main body heat bending portion 12 are bent together.

[0042] In some embodiments, the other end of the rubber cap body 1 away from the rubber cap cover 2 is provided with an inward folding structure that bends inwardly toward the rubber cap body 1. One end of the rubber cap body 1 away from the rubber cap cover 2 is provided with a printed pattern.

[0043] In summary, the heat shrinkable rubber cap provided by the utility model is provided with a lining member 3 consisting of a lining body 31 and an opening handle 32 on the rubber cap body 1, the lining body 31 is attached to the inner wall of the rubber cap body 1, and the opening handle 32 passes through the joint on the rubber cap body 1 and is exposed to the outside of the rubber cap body 1; the pattern or concave-convex texture on the lining body 31 can be observed through the transparent or translucent rubber cap body 1, and since the pattern or concave-convex texture used for anti-counterfeiting is provided on the lining body 31 inside the rubber cap body 1, the anti-counterfeiting measures are not easily destroyed from the outside of the rubber cap body 1, thereby improving the anti-counterfeiting effect of the heat shrinkable rubber cap. Moreover, when an external force pulls the opening handle 32, the opening handle 32 will simultaneously destroy the rubber cap body 1 and the lining body 31, and the damaged heat shrinkable rubber cap cannot be restored, and the remaining part of the damaged rubber cap body 1 will remain at the bottle mouth position, resulting in the inability to install a new heat shrinkable rubber cap, further improving the anti-counterfeiting effect of the heat shrinkable rubber cap. In addition, the heat shrinkable adhesive cap has the advantages of simple structure, easy manufacture and low production cost.

[0044] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
