Description

Technical Field

[0001] The utility model relates to the field of packaging bags, in particular to a packaging bag with a double sealing structure. Background Art

[0002] Packaging bags have many roles in daily life, some of which include:

[0003] 1. Packaging bags can provide protection to prevent items from being damaged, contaminated or deteriorated, especially during transportation and storage;

[0004] 2. They allow people to carry their purchases, such as food, gifts, books, etc., more conveniently;

[0005] 3. Commercially, packaging bags can become a carrier of brand promotion, promoting products and services through printed logos and slogans.

[0006] Although the existing technology can achieve a certain packaging effect during use, it has the following defects: although the existing packaging bags have multiple sealing effects, they lack the problem of optimizing the protective effect of the bag body, resulting in low safety when packing some fragile items. In view of this, we propose a packaging bag with a double sealing structure to solve the above problem. Utility Model Content

[0007] The utility model aims to solve the problems existing in the background technology and proposes a packaging bag with a double sealing structure.

[0008] The technical solution of the utility model: a packaging bag with a double sealing structure, comprising a box body, two snap fasteners, a Velcro and a mounting groove, the inner surface of the upper end of the box body is provided with a Velcro, the outer wall of the upper end of the box body is provided with two snap fasteners, an empty bag is provided inside the box body, the outer wall of the box body is provided with a mounting groove, and an air bag is provided inside the mounting groove;

[0009] The device can have two sealing effects when in use, one of which is to use the second snap fastener to seal the box body and the handle to prevent the items from dumping out, and the second is to use Velcro to seal the bag mouth. Using the two effects at the same time can optimize the sealing effect, and the box body of the device is set to be double-layered, and the middle layer is an empty bag. The empty bag can be filled with gas. The filling of the gas is controlled by an air bag with two valves fixed on one side. When loading some relatively fragile items, the one-way valve one can be opened, and the air bag can be pressed repeatedly, and the air bag will fill the empty bag with gas. When deflation is required, just open the one-way valve two and press the air bag repeatedly.

[0010] Preferably, a one-way valve is provided on the outer wall of one side of the installation groove, and a connecting pipe is provided between the one-way valve and the airbag.

[0011] Preferably, a second one-way valve is provided on an outer wall of one side of the installation groove, and a second connecting pipe is provided between the second one-way valve and the airbag.

[0012] Preferably, a transmission tube is provided between the airbag and the hollow bag.

[0013] Preferably, a handle is provided at the upper end of the box body, a first snap fastener is provided at the opposite side of the upper end of the handle, and a second snap fastener is provided at the lower end of the handle.

[0014] Preferably, a bottom plate is provided at the lower end of the box body, and a base is provided at the lower end of the bottom plate.

[0015] Preferably, grooves are provided in the middle of the outer walls on both sides of the box body.

[0016] Compared with the prior art, the advantages of the present invention are:

[0017] First, the utility model can utilize the snap buckle and the Velcro to achieve a double sealing effect on the box body, thereby optimizing the preservation effect of the items.

[0018] 2. Based on beneficial effect 1, the device can utilize the airbag in conjunction with two valves to inflate and deflate the empty bag inside the box, thereby achieving the effect of protecting fragile items.

[0019] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
