Sealing anti-theft bottle cover

Abstract

The invention relates to a plastic bottle cover, and in particular relates to a sealing anti-theft bottle cover. The bottle cover comprises a cover body consisting of a top cover and a cover barrel and an anti-theft ring, wherein the cover barrel is connected with the anti-theft ring through a connecting bridge; the inner side wall of the cover barrel is provided with threads; the inner side of the top cover is provided with a first sealing ring and a second sealing ring; the first sealing ring is vertically connected with the top cover; the second sealing ring is inclined towards the direction of the first sealing ring; the inner side wall of the anti-theft ring is provided with a bulge; the bulge consists of an upper end face and a lower inclined plane; the upper end face and the lower end face are connected through a circular arc; an included angle alpha is formed between the upper end face and the inner side face of the anti-theft ring; the included angle alpha ranges from 95 to 105 degrees; an included angle beta is formed between the lower inclined plane and the outer side face of the anti-theft ring; and the included angle beta ranges from 25 to 35 degrees. The bottle cover has favorable anti-theft and sealing effect, the mounting difficulty of the sealing anti-theft bottle cover is reduced, the production efficiency is improved, and the production cost is lowered.

Description

technical field [0001] The invention relates to a plastic bottle cap, in particular to a sealed anti-theft bottle cap. Background technique [0002] Plastic anti-theft caps are a commonly used packaging form for bottle packaging at present. Its sealing and anti-theft characteristics make plastic anti-theft caps develop rapidly, especially in the field of beverages. The plastic caps of commonly used beverage bottles are generally It consists of a bottle cap body and an anti-theft ring, and a connecting bridge is set between the bottle cap body and the anti-theft ring. When opening the cap, the connecting bridge needs to be broken to open the bottle cap, thereby ensuring the safety of the product. When consumers use beverage bottles, in addition to high requirements on the sealing effect of the bottle cap, they always hope that the higher the anti-theft strength of the bottle cap, the better, so as to ensure the safety of the beverage in the beverage bottle as much as possible...

Problems solved by technology

When consumers use beverage bottles, in addition to high requirements on the sealing effect of the bottle cap, they always hope that the higher the anti-theft strength of the bottle cap, the better, so as to ensure the safety of the beverage in the beverage bottle as much as possible. However, when manufacturers produce beverages, they not only need to consider the anti-theft strength of the bottle cap, but also the difficulty of installing the bottle cap, because if the installation of the bottle cap is too difficult to pursue the anti-theft strength, it will inevitably make the bottle cap difficult to install. Reduced production efficiency and increased costs
