Safe twist-open cap

Abstract

The invention discloses a safe twist-open cap. The safe twist-open cap comprises a cap top and a cylindrical cap wall formed by downward extending of the outer edge of the cap top, wherein two convex rings which are parallel to each other and surround the cap wall are arranged at the lower part of the cap wall; an annular groove is formed in a position between the two convex rings; a plurality of U-shaped slits are formed in the groove bottom of the annular groove along the circumferential direction of the cap wall; the cap wall at the upper side of the U-shaped slits inclines inwards to form punching openings penetrating through the cap wall; the cap wall between adjacent punching openings form bridges; the cap wall below the punching openings form anti-theft rings; and the anti-theft rings are connected with the cap wall above the punching openings through the bridges. The safe twist-open cap effectively solves the problem that an operator is prone to hurt in the uncapping process of a twist-open cap in the prior art, the safety of the twist-open cap in the uncapping process is greatly improved, and the practical value is high.

Description

technical field [0001] The invention relates to the technical field of packaging containers, in particular to a safe twist-off cap. Background technique [0002] The twist-off cap installed on the mouth of a container such as a tank has the following structure: a top, a side edge of the top, and a synthetic resin gasket bonded to the inner side of the top, and an anti-theft ring on the lower side of the side edge. side edge connection. By inserting into the mouth of the container and exerting a certain pressure on the top of the cover, the sealing gasket is in contact with the mouth of the container and has a certain amount of compression. It is pulled by the side edge of the cover and the thread on the mouth of the packaging container, the anti-theft ring and the curling seal of the mouth of the packaging container. , so that the twist-off cap can be well sealed on the container and ensure airtightness. When opening, hold the container with one hand, and pinch the contain...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that the operator is easily injured during the opening process of the twist-off cap in the prior art, and to provide a safe twist-off cap, which can greatly improve the safety of the twist-off cap during the opening process

[0005] Another object of the present invention is to provide a safe twist-off cap to solve the problems of the prior art twist-off cap, such as the pressure on the top of the cap that is too high to cause the collapse of the container and the deformation of the neck of the anti-theft ring of the container. It can greatly reduce the problems of container collapse and container anti-theft ring neck deformation caused by unscrewing the cap during the capping process.

[0006] The third purpose of the present invention is to provide a safe twist-off lid to solve the problem that the twist-off lid of the prior art is prone to lack of anti-theft function or unknowingly deteriorates the product and seriously affects the reputation of the product manufacturer. The cover has the characteristics of simple structure, good anti-theft sealing and easy opening
