Bottle cap anti-counterfeiting device

Abstract

The invention discloses a bottle cap anti-counterfeiting device. The bottle cap anti-counterfeiting device comprises a tube base, wherein the tube base is of a cylindrical shell; the upper surface ofthe tube base is provided with a convex arc surface; a through hole is formed in the middle of the arc surface of the tube base; the upper end of the tube base is provided with an upper cap; the lowersurface of the upper cap is provided with a concave arc surface matched with the convex arc surface of the tube base; and a soft plug is arranged on a position of the concave surface, opposite to thethrough hole, of the upper cap. The bottle cap anti-counterfeiting device has a simple structure; through cooperation of the upper cap and the tube base, sealing is realized; the upper cap is slid and turned along the tube base, so that the upper cap is convenient to open; due to the soft plug, the overall airtightness is ensured; through coordination of the upper ends of inserting plates and slots, locking of the tube base and the upper cap is realized; the inserting plates can be broken along the positions of lateral grooves, so that limitation is released; due to design of an internally-arranged locking piece, unartificial collision damage is avoided, and the use strength is improved; through rotation of a twist ring, control of the inserting plates is realized, opening is convenient,the upper cap is not rigidly limited after the upper ends of the inserting plates are broken, and use situations of the bottle cap can be effectively distinguished, so that counterfeit prevention is realized.

Description

technical field [0001] The invention relates to the technical field of bottle cap packaging, in particular to an anti-counterfeit bottle cap device. Background technique [0002] At present, there are many kinds of anti-counterfeiting bottle cap devices for alcoholic beverages. The previous similar anti-counterfeiting structures only had a single anti-counterfeiting performance structure of twisting the teeth or turning out the flange. Due to the importance of bottle caps to the beverage packaging industry Its own structure and material have been continuously developed and improved. Most of the current bottle cap structures still use a cylindrical structure that matches the bottle mouth, and a built-in internal thread that matches the bottle mouth, so that The assembly is realized through the screw connection of the two. The anti-counterfeiting of plastic bottle caps basically stays at a single simple anti-counterfeiting level. It is easy to restore after opening, and has di...

[0002] At present, there are many kinds of anti-counterfeiting bottle cap devices for alcoholic beverages. The previous similar anti-counterfeiting structures only had a single anti-counterfeiting performance structure of twisting the teeth or turning out the flange. Due to the importance of bottle caps to the beverage packaging industry Its own structure and material have been continuously developed and improved. Most of the current bottle cap structures still use a cylindrical structure that matches the bottle mouth, and a built-in internal thread that matches the bottle mouth, so that The assembly is realized through the screw connection of the two. The anti-counterfeiting of plastic bottle caps basically stays at a single simple anti-counterfeiting level. It is easy to restore after opening, and has disadvantages such as poor anti-counterfeiting effect and easy imitation, which is difficult to apply to the anti-counterfeiting requirements of complex markets.
