[0028] The vacuum bag body 1 is made of a cloth-plastic composite material. The cloth-plastic composite material is: the inner layer film and the outer layer fabric are bonded with an adhesive. The inner layer film is: PE film, PVC film, TPU film, EVOH film, multi-layer co-extruded barrier film, PE coating film, the outer layer fabric is: chemical fiber cloth, woven fabric, knitted fabric, the middle layer composite adhesive is: water-based glue, oil-based glue, solvent-based glue, solvent-free polyurethane glue, hot melt adhesive, PUR glue.

[0029] The vacuum bag body 1 includes a three-dimensional lower bag body 11 arranged at the bottom, and an upper bag body fixed at the top opening of the lower bag body 11. In this embodiment, the upper bag body includes a front bag wall 12 and a rear bag wall 13 fixed at the top opening of the lower bag body 11 (the upper bag body can also adopt an upper bag body of other shapes); the tops of the front bag wall 12 and the rear bag wall 13 are fixedly connected to the sealing device 2; in this embodiment, the lower bag body 1 is arranged into a conventional rectangular parallelepiped; after the front bag wall 12 and the rear bag wall 13 are pressed and fixed, they are respectively fixed on the long sides of the rectangular parallelepiped and extend to the midpoint position of the short sides of the rectangular parallelepiped.

[0030] The lower bag body 11 includes a bottom surface disposed at the very bottom, and a plurality of segmented side walls fixed to the outer edges of the bottom surface. The outer edges of the bottom surface and the side walls, as well as the junctions between the segmented side walls, are fixedly connected to form support strips. The junctions between the bottom surface and the side walls, between the side walls, at the top of the lower bag body and the front and rear bag walls, and at the front and rear bag walls are all secured using a hot air pressing process to form heat-sealed edges 14. The width of the heat-sealed edges 14 ranges from 0.5 to 2 cm, with a width of 1 cm being used in this embodiment, and serves as support strips.

[0031] The three-dimensional vacuum storage bag with a flip cover also includes a flip cover 7, one side of which is fixedly or detachably connected to one side of the top opening of the lower bag body 11, and the remaining side of the flip cover 7 is detachably connected to the remaining sides of the top opening of the lower bag body 11; when all four sides of the flip cover 7 are connected to the four sides of the top opening of the lower bag body 11, the upper bag body is located in the cavity formed by the flip cover 7 and the lower bag body 7. One side of the flip cover 7 is fixedly connected to one side of the top opening of the lower bag body 11 by integral molding, and the remaining side of the flip cover 7 is detachably connected to the remaining sides of the top opening of the lower bag body 11 by a fixing assembly; or, the four sides of the flip cover 7 are detachably connected to the four sides of the top opening of the lower bag body 11 by a fixing assembly. In this embodiment, one side of the flip cover 7 is fixedly connected to one side of the top opening of the lower bag body 11 by sewing, and the remaining side of the flip cover 7 is detachably connected to the remaining sides of the top opening of the lower bag body 11 by a fixing assembly.

[0032] The fixing components can be snap fasteners and / or adhesive fasteners and / or buttons and holes and / or zipper strips 8 that are arranged correspondingly and cooperate with each other on the edge of the flap 7 and the edge of the top opening of the lower bag body 11. When the fixing component is a zipper strip 8, a zipper pull is provided at one end or both ends of the zipper strip 8.

[0033] In this embodiment, one side of the flap 7 is secured to the heat-sealed edge at the top of the lower bag body 11 by sewing. For convenience, the securing components utilize corresponding zipper strips 8, each with a zipper pull at one or both ends.

In this embodiment, the transparent window 4 is provided on the side wall of the lower bag body 11 and is made of a barrier transparent film approximately two centimeters larger than the through-hole in the side wall of the lower bag body. One centimeter of this barrier transparent film is used for bonding, and the outermost one centimeter serves as a margin. This margin facilitates hot air bonding. Example 2

[0035] On the basis of Example 1, in order to provide a better supporting effect for the lower bag body 11 when loading clothes and make it easier to place clothes into a regular rectangle, the applicant has made further improvements to the lower bag body 11 by providing a supporting device on the side wall of the lower bag body 11. The specific solution is as follows:

[0036] like Figure 3As shown, the supporting device can adopt multiple supporting plates 6 fixed on the side wall. The size of the supporting plates 6 is less than or equal to half of the area of ​​the side wall of the lower bag body 11 and is symmetrically arranged along the center line of the side wall of the lower bag body 11.

[0037] The support plate 6 is made of a material having a hardness greater than that of the vacuum bag body; the support plate 6 can be made of polyester cloth and / or Oxford cloth and / or canvas and / or knitted cloth, and can be fixed to the inner side of the side wall by a hot air process, or by glue or other means, or the support plate 6 can be fixed to the inner side of the side wall by embedding. Example 3

[0038] Or, based on Example 2, Figure 4 As shown, the supporting device can also adopt a plurality of tie bars 5 fixed on the side wall at intervals, and the length of the tie bars 5 is equal to or less than the height of the side wall of the lower bag body.

[0039] The hardness of the tie strip 5 or the support plate 6 is greater than the hardness of the material of the vacuum bag body; the tie strip 5 or the support plate 6 can be made of polyester cloth and / or Oxford cloth and / or canvas and / or knitted cloth, and can be fixed to the inner side of the side wall by hot air process, or by glue or other methods, or the tie strip 5 or the support plate 6 can be fixed to the inner side of the side wall by embedding.
