Lifting open-type anti-counterfeiting bottle cap

Abstract

The invention belongs to a mechanical anti-counterfeiting bottle cap, and relates to a lifting open-type anti-counterfeiting bottle cap, comprising a fixed sleeve fixed on a bottle opening and a movable cover covered on the fixed sleeve, wherein the lower edge of the movable cover is provided with a curled skirt edge; the upper edge of the fixed sleeve is provided with a turned edge which can hook the skirt edge; the middle part of a reversed U-shaped elastic hook support is hinged on the movable cover in a penetrating manner; the left end and right end of a semi-ring-shaped elastic hook opening ring are hinged on the fixed sleeve; the two ends of the elastic hook support are hinged at the left side and right side of the elastic hook opening ring; and the middle part of the elastic hook opening ring is positioned outside the fixed sleeve. The bottle cap provided by the invention has the beneficial effects of being convenient in use and easy to open and counterfeit, having a simple structure, good process property and beautiful appearance, preventing pollution, being sanitary, and being suitable for application and popularization of various bottle caps.

Description

technical field [0001] The invention belongs to a mechanical anti-counterfeit bottle cap, and relates to a lift-open type anti-counterfeit bottle cap. Background technique [0002] At present, all kinds of mechanical anti-counterfeiting bottle caps mainly include pry-off type, twist-off type, tear-off type, top-opening type, and burst ring type. Their common characteristic is to destroy joint point and play anti-counterfeiting mark. The main problems of each are: unstable opening force (such as single anti-aluminum cap), hand injury when opening (such as tearing the aluminum cap), complicated anti-counterfeiting process, poor reliability (such as burst ring cap), and dust accumulation at the connection point (such as top-opening bottle caps) unhygienic and other problems and defects. And all kinds of mechanical anti-counterfeiting bottle caps also have a common defect, that is, they all rely on the rotational lift of the thread to achieve the purpose of opening the...

AI Technical Summary

Problems solved by technology

The main problems of each are: unstable opening force (such as single anti-aluminum cap), hand injury when opening (such as tearing the aluminum cap), complicated anti-counterfeiting process, poor reliability (such as burst ring cap), and dust accumulation at the connection point (such as top-opening bottle caps) problems and defects such as unhygienic

And all kinds of mechanical anti-counterfeiting bottle caps also have a common defect, that is, they all rely on the rotational lift of the thread to achieve the purpose of opening the bottle cap, and for most consumers who are not familiar with the direction of thread opening, they often use force Rotate in the opposite direction, so it is easy to cause the thread to slip and cannot be opened
