AI Technical Summary
In repeated use of sealed bags with plug bottom structure, the stress tension point holes at the connection between the plug bottom and the bag main body are prone to occur.
A semi-ring arc-shaped edge protection angle is added to the three sides of the connection point between the bottom of the insertion bottom and the bag main body, and the force is subjected to the conversion point to the arc, thereby protecting the central stress point omnidirectionally.
Through the design of curved edge protection angles, the durability and solidity of the sealed bag are improved, avoiding hole problems caused by stress concentration.

Abstract
Description
Technical Field
[0001] The utility model relates to the field of vacuum sealing bags, in particular to a bottom-inserted force-bearing protection sealing bag. Background Art
[0002] The sealed bag with an inserted bottom structure has a point connection between the inserted bottom and the bag body. Therefore, when the bag is filled with items, the bag body stretches the connection point, which becomes a stress-bearing point and is prone to holes during repeated use. Utility Model Content
[0003] In view of the problems existing in the prior art, the utility model provides a bottom-inserted force-protected sealing bag, and arc-shaped edge protection corners are added on both sides of the connection between the bottom and the bag body to convert point force into arc force, thereby protecting the center point 360 degrees from force and providing all-round protection, making the sealing bag stronger and more durable.
[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:
[0005] The bottom-inserted force-protected sealed bag has a bag body including a bottom film and a front film that are heat-sealed on three sides, and a sealing zipper is provided on one side. The excess front film near one end of the bag body is folded to form a bottom insert. The side of the bag body is Y-shaped, and arc-shaped edge protection corners are heat-sealed on three sides of the connection point between the bottom insert and the bag body.
[0006] A further improvement is that the sealing zipper of the bag body is arranged on the insert bottom, which makes it more convenient to seal the zipper.
[0007] A further improvement is that the protection angle is semi-circular.
[0008] A further improvement is that a sealing air valve is provided on the front film of the bag body.
[0009] A further improvement is that the front film is a transparent film. Beneficial Effects
[0010] The sealed bag is stressed along the entire arc line on three sides of the stress points of the insert bottom and the bag body, protecting the central stress point from stress, converting the point stress into arc stress, protecting the concentrated stress point in all directions, and making the sealed bag stronger and more durable. At the same time, the sealing zipper is arranged on the insert bottom, which makes it more convenient to seal the zipper. BRIEF DESCRIPTION OF THE DRAWINGS
[0011] Figure 1 It is a schematic diagram of the three-dimensional structure of the utility model;
[0012] Figure 2 It is the front view of the utility model. DETAILED DESCRIPTION
[0013] like Figure 1 , Figure 2As shown, the bag body of the utility model includes a bottom film 1 and a front film 2 which are heat-sealed on three sides, and a sealing zipper 3 is provided on one side. The surplus front film near one end of the bag body is folded into an inserted bottom 4, and the side surface of the bag body is Y-shaped. Semi-circular arc-shaped edge protection corners 6 are heat-sealed on three sides of the connection point 5 between the inserted bottom and the bag body, and the sealing zipper 3 of the bag body is arranged on the inserted bottom 4.
[0014] A sealing air valve 7 is provided on the front film 2 of the bag body.
[0015] The front film 2 is a transparent film.
[0016] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
