A claw-type twist-off cap with a safety button structure

Abstract

The invention relates to a claw type unscrewing cap with a safety button structure. The claw type unscrewing cap comprises a cap top, a cap wall and a cap claw, wherein the cap top, the cap wall and the cap claw are mutually connected, the middle of the cap top is a horizontal portion, the two ends of the horizontal portion extend downwards along the horizontal line to form inclined portions, the end portions of the inclined portions extend to form bending portions and are connected with one end of a connecting portion, and the other end of the connecting portion is connected with the cap wall. By adding the elastic deformation range, the probability of plastic deformation can be greatly reduced, meanwhile, the force value, absorbed by vacuum, of the plane portion is reduced, and therefore the vacuum suction value is reduced.

Description

technical field [0001] The invention relates to the field of bottle caps, in particular to a 30MTB claw-type unscrewable cap with a safety button structure. Background technique [0002] The 30MTB twist-off cap is the smallest type of cap on the market, and its adoption rate in the market is relatively low. The cap puts forward extremely high requirements, requiring that the raised part of the safety button of the bottle cap has a small supporting force, that is, the vacuum suction value is stable, and it has good visibility, so that consumers can easily identify it. Among them, the stability of the vacuum suction value is the most critical. , due to the small size of the cover, the distance between the safety button structure and the injection groove at the bottom of the unscrewed cover is relatively close, and the vacuum suction value formed is relatively large, which makes the external damage to the safety button the most direct, resulting in a large and unstable suction ...

[0002] The 30MTB twist-off cap is the smallest type of cap on the market, and its adoption rate in the market is relatively low. The cap puts forward extremely high requirements, requiring that the raised part of the safety button of the bottle cap has a small supporting force, that is, the vacuum suction value is stable, and it has good visibility, so that consumers can easily identify it. Among them, the stability of the vacuum suction value is the most critical. , due to the small size of the cover, the distance between the safety button structure and the injection groove at the bottom of the unscrewed cover is relatively close, and the vacuum suction value formed is relatively large, which makes the external damage to the safety button the most direct, resulting in a large and unstable suction value. situation, unable to meet the requirements of food packaging

[0003] The few safety button structures currently in the market for 30MTB unscrew caps have flaws in their elastic deformation range, which is easy to enter the plastic deformation range during external extrusion, collision, and flow between processes, forming Permanent deformation, at the same time, the vacuum suction value is too large, it is difficult to adjust to the standard value, and the suction value is greatly affected by external factors such as raw materials, equipment, molds, etc., and the resistance stability is poor
