Disposable vacuum bottle cap and method for opening disposable vacuum bottle cap

Abstract

The invention provides a disposable vacuum bottle cap and a method for opening the disposable vacuum bottle cap, and relates to the field of packaging articles. The disposable vacuum bottle cap comprises a lock catch and a cap body, and the cap body is provided with a lock cylinder. The lock catch is of a ring-shaped structure, and a flange is arranged on the inner wall of the lock catch. The capbody is of a bowl-like structure, the radius of the opening end of the cap body is larger than the radius of the closed end of the cap body, the cap body is located in an inner cavity of the lock catch, and the interior of the cap body is in a vacuum shape. The lock cylinder includes an outer tube arranged at the closed end at the top of the cap body in a penetrating manner, and the outer tube andthe cap body are subjected to sealing treatment. Compared with the prior art, the disposable vacuum bottle cap is provided with the lock catch and the cap body which are matched, the interior of thelock catch is arranged to be in a vacuum shape, and the vacuum negative pressure principle is used for fixing the bottle cap; and in addition, in the opening process, only air needs to enter the inside of the cap body to break the vacuum environment, the bottle cap can be detached, the opening manner is simple and convenient, and the bottle cap can be easily opened by anyone.

Description

technical field [0001] The invention relates to the technical field of packaging supplies, in particular to a disposable vacuum bottle cap and a cap opening method thereof. Background technique [0002] The bottle is a very common packaging structure. In the prior art, in order to prevent some bottles from being opened after the packaging is completed, many disposable bottle packaging structures (such as beer bottles and screw bottles) have appeared. plastic ring structure at the bottom of the cover). However, most of the packaging structures are mechanical packaging structures. Generally, the mechanical connection structure needs to be destroyed when disassembling such a packaging structure. Therefore, the disassembly process is troublesome, time-consuming and laborious. [0003] For example: when opening a wine bottle, the bottle cap needs to be tilted up. Although it can be opened quickly with the help of a bottle opener, it still requires a certain amount of force, and ...

AI Technical Summary

Problems solved by technology

However, most of the packaging structures are mechanical packaging structures. Generally, the mechanical connection structure needs to be destroyed when disassembling such a packaging structure. Therefore, the disassembly process is troublesome, time-consuming and labor-intensive.

[0003] For example: when opening a wine bottle, the bottle cap needs to be tilted up. Although it can be opened quickly with the help of a bottle opener, it still requires a certain amount of force, and the bottle cap is prone to fly off during the process of opening the bottle. Situation of hitting someone

[0004] For another example, when opening the screw cap, since the bottom of the cap is fixed with the plastic ring, a certain amount of force is required to destroy the connection structure, so it is more laborious to open the cap.
