A kind of easy-release sealing anti-theft bottle cap and its production process

Abstract

The invention provides an easy-release sealed anti-theft bottle cap and its production process. The bottle cap includes a bottle cap body, a connecting bridge, an anti-theft ring and an annular gap. At the bottom of the bottle cap body, the bottle cap body and the anti-theft ring are connected by a connecting bridge. The anti-theft ring is integrally formed with a number of square through holes distributed at equal arc intervals. The inner wall of the anti-theft ring is provided with several equal circular holes. The raised buckle with arc spacing distribution, the angle β formed by the upper surface of the buckle and the inner wall of the anti-theft ring is 75° to 85°, and the angle α formed by the lower surface of the buckle and the horizontal plane of the bottom end of the anti-theft ring is 40° ° to 50°, the top inner wall of the bottle cap body is provided with a circle of ring-shaped reinforcing ribs, and the top of the bottle cap body is provided with an arc-shaped protrusion. The bottle cap is easy to demould, has good sealing performance and anti-theft performance; the production process can effectively reduce production procedures and production costs, and can effectively improve product quality and production efficiency.

Description

technical field [0001] The invention relates to the technical field of plastic bottle caps, in particular to an easy-release sealed anti-theft bottle cap and a production process thereof. Background technique [0002] In the existing packaging technology, after the bottle cap and the bottle body are tightly packed, in order to prevent the bottle cap from being opened maliciously, an anti-theft ring is often provided on the bottle cap. The existing bottle cap is generally provided with an anti-theft ring at the bottom of the bottle cap. , the anti-theft ring and the bottle cap body are connected by several breakable connecting bridges, and the anti-theft function of the bottle cap is realized by setting the anti-theft ring. After the bottle cap is tightened and assembled to the bottle body, the anti-theft ring on the bottle cap will It is stuck on the positioning ring of the bottle body. When the bottle cap is unscrewed for the first time, the connecting bridge is disconnecte...

Problems solved by technology

[0003] However, there are still many bottle caps with poor sealing and anti-theft performance on the market. When the bottle cap is opened for the first time, the anti-theft ring is twisted out together with the bottle cap, which cannot achieve the expected anti-theft effect. The situation is mainly due to the deformation of the anti-theft ring or defects in the structure of the anti-theft ring

In the bottle cap injection molding process, the demoulding process has a very important impact on the quality of the injection-molded bottle cap. Improper handling of the demoulding process can easily lead to uneven force on the cap during demoulding, resulting in the cap and the The anti-theft ring is deformed, and the structure design of the anti-theft ring on some bottle caps is unreasonable due to the fastening with the bottle body positioning ring, which is often easy to even cause the anti-theft ring to be deformed or damaged when the injection molding is demolded, and ultimately leads to poor sealing and anti-theft performance of the bottle cap

[0004] In the existing bottle cap production technology, considering that the connecting bridge is easy to break due to force, most of the bottle caps and anti-theft rings are integrally injection-molded first, and then the bottle caps and anti-theft rings are connected by bottle cap ring cutting equipment. Circumferential processing to form evenly spaced connecting bridges, such a production process still has the following defects in the actual production process: more production processes, more manpower and material resources invested, higher production costs, and it is not conducive to the improvement of production efficiency Further improve
