Anti-counterfeiting bottle cover with clamping upper spiral top

Abstract

The invention discloses an anti-counterfeiting bottle cover with a clamping upper spiral top, which relates to a container sealing device which is used for displaying uncommitted opening and closing, and can avoid repeated filling. The invention aims at providing the anti-counterfeiting bottle cover with the clamping upper spiral top, which is simple in structure, and can have an obvious changed structure when being opened. The anti-counterfeiting bottle cover comprises an outer cover, an upper spiral top part and a spirally lifting base, wherein the upper spiral top part and the spirally lifting base are arranged in the outer cover, a circumferential linking device is arranged between the upper spiral top part and the outer cover, the outer cover and the spirally lifting base are connected by a axial fixing device, at least one spirally lifting end surface is arranged at the spirally lifting base alone the circumferential direction, the upper spiral top part comprises a spirally lifting device which is supported on the end surface, the spirally lifting base further comprises a fixing device which can be fixed onto an opening part and a neck part of a container, the top of the outer cover is an end cover which is in brittleness connection, and the end cover can enable the brittleness connection to be fractured under the propping lifting action of the end cover on the upper spiral top part, when the spirally lifting device moves to the apex of the end surface.

Description

technical field [0001] The invention relates to a container sealing device, in particular to an anti-counterfeiting bottle cap for displaying unauthorized opening and avoiding repeated filling. Background technique [0002] In order to avoid shoddy products, false ones, and to ensure the interests and personal safety of users, a container sealing device is needed. After the device is initially opened, there will be obvious structural changes, and it cannot be restored to the state before the initial opening. , the structure of the obvious change of the sealing device warns the user that it has been opened, so that the counterfeiter cannot reseal with the original sealing device, and cannot refill the counterfeit and inferior product (such as fake wine) into the container unless the original seal is corrected. The device is destructively dismantled. And the anti-counterfeiting visibility mark of existing anti-counterfeiting bottle caps is all positioned at the subtle part of...

AI Technical Summary

Problems solved by technology

However, the anti-counterfeiting visibility marks of the existing anti-counterfeiting bottle caps are all located on the subtle parts of the bottle cap, which is not easy to attract the attention of users, so its anti-counterfeiting effect is not very ideal.
