Anti-counterfeiting structure of bottle cap

Abstract

The invention relates to an anti-counterfeiting structure of a bottle cap. The anti-counterfeiting structure comprises an upper cap, a base and an anti-counterfeiting ring. The base is mounted on a bottle opening in an embedded mode. The upper cap is mounted above the base in a threaded connection mode. The anti-counterfeiting ring is arranged at the junction of the upper cap and the base and comprises an upper ring, a lower ring and a plurality of connecting bridges for connecting the upper ring with the lower ring. The upper ring and the lower ring are nested on the upper cap and the base correspondingly. The junction of the upper cap and the base is sleeved with the connecting bridges in an embedded mode. According to the anti-counterfeiting structure, the upper cap and a lower cap of the bottle cap are closed, the anti-counterfeiting ring encircles the exteriors of the upper cap and the lower cap, and when the upper cap is rotated anticlockwise, the connecting bridges at the ring part, close to the upper cap and the lower cap, of the encircling-type anti-counterfeiting ring are broken off or burst open due to rotation stress. The anti-counterfeiting structure of the bottle capis difficult to counterfeit after being subjected to one-time damage, the requirements for the technology are high, and compared with an existing anti-counterfeiting bottle cap, the anti-counterfeiting effect is better.

Description

technical field

[0001] The invention relates to the technical field of bottle caps, in particular to an anti-counterfeiting structure for bottle caps. Background technique

[0002] The bottle cap acts on the bottle, and for different functions, the bottle cap can be designed with diverse functions and different shapes. For the high-end products that appear on the market, the packaging is also required to have anti-counterfeiting function, and its anti-counterfeiting function can be applied to the packaging box, bottle body or bottle cap.

[0003] At present, the anti-counterfeiting bottle caps on the market are mainly made of aluminum-plastic combination and LDPE (low-density polyethylene) and glass bottle mouths are occluded to start sealing. The components produced by different equipment are reassembled into one body, and the anti-counterfeiting structure includes: Upper cover, lower seat and explosion-proof ring. However, each component of the azimuth structure in the p...
