Full-plastic anti-counterfeiting cap, aluminum plastic anti-counterfeiting cap and combining connection sleeve used for anti-counterfeiting caps

Abstract

The invention discloses a full-plastic anti-counterfeiting cap. The full-plastic anti-counterfeiting cap comprises an outer cap body and an inner cap body with internal threads. The inner cap body is fixed to the interior of the outer cap body. The outer cap body and the inner cap body are fixed to a bottle mouth through a combining connection sleeve. The combining connection sleeve comprises an outer sleeve body and an inner sleeve body sleeved with the outer sleeve body. The upper part of the inner sleeve body is exposed out of the outer sleeve body and provided with external threads matched with the internal threads. Lower rotation stopping teeth are arranged on the outer side wall of the lower part of the inner sleeve body and matched with first rotation stopping teeth on the inner wall of the outer sleeve body. Second rotation stopping teeth are arranged below the first rotation stopping teeth and matched with rotation stopping teeth on the bottle mouth. The lower part of the inner sleeve body is provided with a bayonet structure which is matched with a clamping table on the bottle mouth. The bayonet structure and the lower rotation stopping teeth are arranged on the outer ring face of the inner sleeve body in a staggered mode. The full-plastic anti-counterfeiting cap is simple in structure, the inner sleeve body consumes less material, and the production cost is low.

Description

technical field [0001] The invention relates to an anti-counterfeit bottle cap, in particular to an anti-counterfeit bottle cap and a combined connection sleeve which can reduce material consumption and save costs. Background technique [0002] The bottle caps of high-grade wine and beverages often need to possess the effect of sealing and anti-counterfeiting, and the bottle caps in the prior art mainly contain two kinds: all-plastic cap products and aluminum-plastic cap products, all-plastic cap products figure 1 ) is generally composed of five parts: the outer cover, the inner cover, the outer cover 1', the inner cover 2' and the inner plug, wherein the inner cover 2' is provided with two matching structures formed with the bottle mouth 3', and one is the inner cover 2' The bayonet fixing structure 21' between the inner sleeve and the bottle mouth is used to fix the bottle cap radially, and the other is the anti-rotation structure 22' between the inner sleeve and the bottl...

[0002] The bottle caps of high-grade wine and beverages often need to possess the effect of sealing and anti-counterfeiting, and the bottle caps in the prior art mainly contain two kinds: all-plastic cap products and aluminum-plastic cap products, all-plastic cap products figure 1 ) is generally composed of five parts: the outer cover, the inner cover, the outer cover 1', the inner cover 2' and the inner plug, wherein the inner cover 2' is provided with two matching structures formed with the bottle mouth 3', and one is the inner cover 2' The bayonet fixing structure 21' between the inner sleeve and the bottle mouth is used to fix the bottle cap radially, and the other is the anti-rotation structure 22' between the inner sleeve and the bottle mouth to fix the bottle cap circumferentially, and the bayonet on the bottle mouth The matching structure 31' is located on the upper part of the bottle mouth, and the anti-rotation matching structure 32' of the bottle mouth is located on the neck of the bottle, so the inner sleeve 2' must have sufficient length to set the bayonet structure and the anti-rotation structure, and the bayonet structure should be set at the stop. The top of the rotating structure is used to match the bayonet fitting structure and the anti-rotating fitting structure of the bottle mouth, so that the inner sleeve uses more materials and the production cost is high; while the existing aluminum-plastic caps not only have the above-mentioned technical problems, but also the aluminum-plastic caps The cut position can only be set on the upper part of the aluminum cylinder, and the structure is single, which is not conducive to the distribution design of the decorative parts of high-end wine bottle caps
