Description

The pressure-opening storage device with the lid lifted and pre-forced

technical field

The invention relates to a pressure-opening type storage device with a pre-forced opening of the cover, which is a cylinder for storing granular, powdery, paste-like or paste-like or liquid contents in a hand-held or mechanism clamping type Shaped, or approximately cylindrical, or multi-faceted cylindrical hollow container structure.

background holding technique

Traditional hand-held or mechanism-clamped hollow containers can be filled with granular, powdery, paste-like or paste-like or liquid contents, and the cover is usually set independently. This structure has the following disadvantages: (1) After opening, the container and the cover are divided into pieces, which is troublesome to recycle; (2) If the contents are released by side pressure, and the side pressure surface is wide, it is easy to press by mistake; (3) The cover is opened The positional relationship between the back and the shell is unstable, which hinders the release of the contents.

In addition, traditional pressure-opening storage devices include the following three methods, each of which is relatively missing:

1. The pressure-opening type cover is separated from the storage device after being pressed, and the stored content is mixed into it;

2. The pressure-opening type cover is not completely separated after being opened under pressure. When the pressure disappears, the cover will spring back and prevent the release of the contents;

3. If the cover is opened under pressure, if the storage device is deformed by external pressure and the cover is opened, the pressure will be released when the pressurized part of the cover is opened, and the cover will still spring back.

Contents of the invention

The main purpose of the present invention is to provide a pressure-opened storage device with a cover that is lifted and pre-forced, which is a hand-held or mechanism-clamped storage device for loading granular, powdery, slurry or paste or liquid content. Cylindrical, or near-cylindrical, or multi-faceted cylindrical hollow containers for objects, and the outer periphery of the cylindrical shell is specially made to be held by human hands or held by a mechanism, and it is pressurized by the outside of the shell of the hollow container The force-bearing surface of the cover and the position of the release port of the content are respectively arranged at the two ends of the cylindrical hollow container shell in the axial direction. Open the cover at the other end to release the contents, or lift the cover at the other end by hand and pressurize the force-bearing surface to release the contents or pour out the contents directly. The relationship between the cover and the storage device There is a flexible sheet-like structure between them, which is used to keep the cover and the shell apart after being opened. The relative steady-state relationship between the cover and the shell is that when the cover is closed to the storage device, the sheet-like structure held together is held together. It is bent and is in a pre-stressed state in the direction of opening, and after the cover is opened under pressure, it can maintain the stable state of opening the cover, avoiding hindering the release of the contents inside the shell of the hollow container, and the cover is lifted After opening, it will not disperse with the shell, will not be mixed into the release, and is conducive to recycling.
