Description

Technical Field

[0001] This utility model relates to the field of sealed packaging bag technology, and more specifically, to a reusable sealed packaging bag with a double-track interlocking zipper. Background Technology

[0002] Sealed packaging bags are packaging containers that effectively isolate the internal space from the external environment (air, moisture, dust, odors, etc.) through specific materials, structures, or sealing methods. The core is to achieve a sealed space and prevent the exchange of substances inside and outside. They usually use barrier materials, such as polyethylene, polypropylene, polyester, aluminum foil, etc., or a combination of multiple materials to prevent air and moisture penetration.

[0003] A search revealed that Chinese Patent CN220430971U discloses a sealed packaging bag. This utility model's sealed packaging bag provides a handle hole for easy carrying by the user, while the closable sealing strip at the sealing end allows the sealed packaging bag to be reused and also helps to isolate the contents of the bag from the outside air. On the other hand, the positioning point at the handle end allows the connected automated packaging machine to identify the position of the bag, thereby enabling precise cutting of the roll of sealed packaging bag, improving both packaging efficiency and accuracy.

[0004] When the above-mentioned sealed packaging bag is used, the sealed packaging bag is a single layer, that is, the bag body is formed by a single material base material, without any auxiliary layer with barrier or reinforcement functions. At the same time, the thickness of the single-layer base material is usually thin, and the bag body itself has no elastic support and cushioning space. The items inside the bag are easily damaged by external force collisions, which in turn affects the service life of the sealed packaging bag. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a reusable sealing packaging bag with a double-track interlocking zipper, which aims to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a reusable sealed packaging bag with a double-track interlocking zipper, comprising a first bag body and a bag head, wherein the bottom end of the bag head is fixedly connected to the first bag body, a double-track interlocking zipper is fixedly installed on the bag head, a partition is fixedly connected inside the first bag body, a second bag body is fixedly connected to the bottom end of the partition, a base is fixedly connected to the bottom end of the first bag body, and an air inlet assembly is provided on the base, the air inlet assembly comprising a first air pipe, a plurality of second air pipes, an air inlet head, a valve and a threaded sealing sleeve, both ends of the first air pipe are fixedly connected to the base, and the top and bottom ends of the plurality of second air pipes are fixedly connected to the first bag body and the first air pipe, respectively.

[0007] Furthermore, the valve is located inside the base and is fixedly mounted on the first air pipe.

[0008] As can be seen, in the above technical solution, when the valve is closed, the inert gas in the interlayer cannot be discharged through the first gas pipe.

[0009] Furthermore, the air inlet head is fixedly embedded in one side of the base, and one end of the air inlet head is fixedly connected to the first air pipe, and the outer side of the threaded sealing sleeve is threadedly connected to the air inlet head.

[0010] As can be seen, in the above technical solution, rotating the threaded sealing sleeve and extending it into the air intake head can prevent external debris from entering the air intake head.

[0011] Furthermore, a pad is fixedly connected to the bottom end of the base, wherein the pad serves to cushion the base.

[0012] Furthermore, two handle holes are provided at the center of both the front and rear sides of the bag head, which serve to facilitate lifting the first bag body.

[0013] Furthermore, two protrusions are fixedly connected to both the front and rear sides of the bag head near the edge, and the protrusions serve to facilitate opening the bag head.

[0014] Furthermore, multiple reinforcing plates are fixedly connected to both the front and rear sides of the first bag body, which can improve the strength of the first bag body.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] 1. This utility model, by setting a double-track interlocking zipper, can provide double isolation for the bag head, effectively isolating external interference. At the same time, it is durable and not easily worn by repeated opening and closing. When the valve is opened, inert gas is injected into the first air pipe through the air pump. The inert gas enters the interlayer between the first bag body and the second bag body through multiple second air pipes. The inert gas in the interlayer forms an elastic buffer layer. When subjected to compression or collision, the inert gas can disperse the impact force. The double-layer structure and the elastic buffer layer can improve the overall service life.

[0017] 2. By setting multiple reinforcing plates, this utility model can disperse the external force borne by the first bag body during use from a local concentration point to the area covered by multiple reinforcing plates and the entire first bag body, so that the external force is evenly transmitted to a larger force-bearing area, significantly reducing the local unit area force on the first bag body, avoiding the first bag body from being damaged due to excessive local force, and further improving the service life of the sealed packaging bag.

Both ends of the first air pipe 901 are fixedly connected to the base 6, and the top and bottom ends of the plurality of second air pipes 902 are fixedly connected to the first bag body 1 and the first air pipe 901, respectively.

[0026] Furthermore, valve 904 is located inside base 6 and is fixedly installed on first air pipe 901. Air inlet head 903 is fixedly embedded on one side of base 6, and one end of air inlet head 903 is fixedly connected to first air pipe 901. The outer side of threaded sealing sleeve 905 is threadedly connected to air inlet head 903.

[0027] Furthermore, a pad 7 is fixedly connected to the bottom of the base 6, wherein the pad 7 serves to cushion the base 6.

[0028] Furthermore, two handle holes 3 are provided at the center of both the front and rear sides of the bag head 2. The two handle holes 3 serve to facilitate lifting the first bag body 1.

[0029] Furthermore, two protrusions 4 are fixedly connected to the front and rear sides of the bag head 2 near the edge, and the multiple protrusions 4 serve to facilitate opening the bag head 2.

[0030] Furthermore, multiple reinforcing plates 8 are fixedly connected to both the front and rear sides of the first bag body 1, and the multiple reinforcing plates 8 can improve the strength of the first bag body 1.

[0031] When the bag head 2 is closed and the front and rear sides of the inside of the bag head 2 are in close contact, the bag head 2 can be opened by moving multiple protrusions 4. The pad 7 can buffer the base 6 to prevent the base 6 from rigidly contacting the ground. Multiple reinforcing plates 8 can disperse the external force borne by the first bag body 1 during use from a local concentration point to the area covered by multiple reinforcing plates 8 and the whole of the first bag body 1, so that the external force is evenly transmitted to a larger force-bearing area, significantly reducing the local unit area force of the first bag body 1, and avoiding the first bag body 1 from being damaged due to excessive local force.
