The technical scheme that the utility model solves its technical problem adopts is:

A squeeze-type vacuum-free multi-faceted three-dimensional vacuum compression bag, including a bag body, the bag body includes a front bag sheet, a rear bag sheet, a top surface, a bottom surface, a lower fastening strip, and an upper fastening strip; the front The middle parts of the two sides of the pocket sheet and the rear pocket sheet are heat-sealed and merged, and the unheated parts of the upper part of the front pocket sheet and the upper part of the rear pocket sheet are opened to form a first fork opening; the lower part of the front pocket sheet and the The unheat-sealed part of the lower part of the back pocket is opened to form a second fork; the connecting edges of the top surface are respectively connected to the edges of the front pocket and the back pocket at the first fork; the bottom surface The connecting edge of the second fork is respectively connected with the edge of the front pocket sheet and the rear pocket sheet;

One side of the top surface is opened to form a pocket, and at least one of the remaining sides of the pocket is provided with a one-way exhaust device for exhausting air in the pocket.

The one-way exhaust device is arranged on one side of the bottom surface.

The one-way exhaust device includes a bag body film, an inner layer film, an exhaust channel, a tensioning device, and a press edge.

An inner film is arranged inside the bag body film, a tensioning device is arranged between the bag body film and the inner layer film, and a pressure edge is arranged on the one-way exhaust device to prevent gas from leaking out; At least one exhaust channel communicating with the inside of the bag body and the outside is spaced apart from the exhaust device.

The tensioning device is non-woven fabric or thread.

The first fork opening is in a Y-shaped structure, and the second fork opening is in an inverted Y-shaped structure. The Y-shaped structure or the inverted Y-shaped structure can be opened at any angle.

An upper fastening strip and a lower fastening strip are respectively arranged on the upper and lower sides of the pocket mouth.

Working principle: During use, the inner film can be stretched to exhaust outwards through the squeezing and tensioning device, so as to discharge the air in the compressed bag, and the inner film is tightly pressed together by atmospheric pressure, and the air will not flow back.

Beneficial effects: the utility model solves the defects in the background technology and has the following advantages:

1. There is no need for an air pump to pump air, and the air in the bag can be discharged by pressing hard. At the same time, the film is pressed by atmospheric pressure so that the air will not flow back into the compressed bag. The structure is simple and reasonable, and it is easy to use.

2. Since the bag body surrounded by the bottom surface and the top surface is three-dimensional, it not only has a beautiful appearance, but also increases the space in the bag body, increases the capacity of the bag body, and enables more items to be placed in the bag body. When in use, the inside of the bag body can still maintain a three-dimensional structure after vacuuming the inside of the bag body, which is convenient for storage.
