Bottle cap for preventing two-dimensional code from being stolen

Abstract

The invention provides a bottle cap for preventing a two-dimensional code from being stolen. The bottle cap comprises an outer cap (1), an inner cap (2) and a sleeve (3), wherein the sleeve (3) sleeves the exterior of a bottle opening of a package bottle, external threads are formed on the outer part of the sleeve (3), internal threads are formed in the outer cap (1), the outer cap (1) is in threaded connection with the sleeve (3), the inner cap (2) is arranged between the outer cap (1) and the sleeve (3), and the inner cap (2) is installed at the bottle opening of the package bottle in a sealing mode. The bottle cap has the beneficial effects that a related two-dimensional code is printed on the inner cap (2) and the outer cap (1), so that the phenomenon that the information of the two-dimensional code cannot be obtained due to abrasion is avoided; breaking teeth (303) are formed between the sleeve (3) and the outer cap (1), and the breaking teeth (303) can be destroyed by the outer cap (1) during rotating to open, so that the bottle cap has an anti-counterfeiting function; and the assembly between the sleeve (3) and the bottle opening of the package bottle as well as between theouter cap (1) and the inner cap (2) is simple and reliable, so that automatic production is facilitated.

Description

technical field [0001] The invention relates to the technical field of packaging, in particular to a bottle cap for preventing theft of two-dimensional codes. Background technique [0002] At present, QR codes on bottle caps are widely used. Most of them are based on the technology of QR codes per bottle. QR codes are printed on the top or inside of bottle caps. Consumers can scan the codes to receive red envelopes, check anti-counterfeiting, and participate in business activities. Merchants can realize anti-counterfeiting, anti-false goods, quality traceability, brand marketing, corporate publicity, big data marketing, etc. through the QR code of the bottle cap. But because it is arranged on the outside of the bottle cap, once it is smeared, damaged, etc., it cannot be read, and the anti-counterfeiting purpose cannot be achieved. Contents of the invention [0003] The technical problem to be solved by the present invention is: aiming at the problems existing in the prior...
