Disposable vacuum bottle cap and cap opening method thereof

Abstract

The invention provides a disposable vacuum bottle cap and a cap opening method thereof, which relate to the field of packaging supplies. The disposable vacuum bottle cap includes a lock buckle and a cover body, and a lock core is arranged on the cover body. The locking buckle is an annular structure, and a flange is arranged on the inner wall of the locking buckle. The cover is a bowl-shaped structure, the radius of the open end of the cover is greater than the radius of the closed end of the cover and is located in the inner cavity of the lock, and the inside of the cover is vacuum-like. The lock core includes an outer tube, which is arranged through the closed end of the top of the cover body, and the outer tube and the cover body are sealed. Compared with the prior art, the present invention uses the principle of vacuum negative pressure to fix the bottle cap by setting the cooperation between the lock buckle and the cover, and by setting the inside of the lock buckle in a vacuum state, and only needs to let air in when opening Breaking the vacuum environment inside the cap can make the bottle cap fall off. This kind of cap opening method is simple and convenient, and anyone can easily open the cap.

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 ...

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.
