Combined short-necked anti-counterfeiting bottle cap and short-necked anti-counterfeiting container

Abstract

The invention discloses a combined short-necked anti-counterfeiting bottle cap and a short-necked anti-counterfeiting container, which relate to sealing devices of containers. The combined short-necked anti-counterfeiting bottle cap is simple in structure, convenient in assembly and suitable for short-necked anti-counterfeiting containers in various specifications. The combined short-necked anti-counterfeiting bottle cap comprises an inner cap and a combined sleeve, the upper portion of the combined sleeve is arranged in the inner cap and matches with the inner cap, the lower portion of the combined sleeve is disposed in a fixing device fixed with a container bottle neck, the fixing device consists of an axial fixing device and a peripheral fixing device, and the lower end of the peripheral fixing device is positioned above the lower end of the axial fixing device.

Description

technical field [0001] The invention relates to a container sealing device, in particular to an anti-counterfeiting bottle cap which avoids repeated filling and sealing. Background technique [0002] For the packaging of short-necked containers, the neck of the bottle cap is required to be shortened accordingly, which increases the difficulty of fixing the bottle cap to the container. At present, the fixing methods used for the bottle caps with this short-necked container on the market are relatively simple, and one of the common methods is the combination of crown cap, liquid outlet pipe, screw port, fixed sleeve, inner cap and outer sleeve. Composition, such as the scheme recorded in the Chinese invention patent with the patent number of 200920018768.6, the liquid outlet pipe and the screw port are axially fixed on the bottle mouth by using the liquid outlet pipe to stretch the expansion claw of the fixed sleeve, and the outer sleeve is matched with the anti-rotation The ...

Problems solved by technology

At present, the fixing methods used for the bottle caps with this short-necked container on the market are relatively simple, and one of the common methods is the combination of crown cap, liquid outlet pipe, screw port, fixed sleeve, inner cap and outer sleeve. Composition, such as the scheme recorded in the Chinese invention patent with the patent number of 200920018768.6, the liquid outlet pipe and the screw port are axially fixed on the bottle mouth by using the liquid outlet pipe to stretch the expansion claw of the fixed sleeve, and the outer sleeve is matched with the anti-rotation Fix the screw mouth relative to the bottle mouth in the circumferential direction. In this fixed connection method, the fixed fit between the bottle cap assembly and the bottle mouth in the circumferential and axial directions is divided into two parts. There are many parts, complex structure, and relatively complicated assembly.
