[0002] Plastic bags are bags made of plastic (commonly used plastics include polypropylene, polyester, nylon, etc.) as the main raw material. They are essential items in people's daily lives and are often used to hold other items. They are widely used because of their low price, extremely light weight, large capacity, and easy storage. However, due to the disadvantages of extremely long degradation cycle and difficult disposal of plastic bags, some countries prohibit their production and use. For this reason, plastic bags made of biodegradable bio-based materials are used more and more frequently in modern society, and with the development of science and technology, their upper-end functions are also constantly being improved.

[0003] In view of this, Chinese Patent No. CN211944416U proposes a biodegradable bio-based plastic bag to improve the safety of objects when the bag is loaded. At the same time, the installed dividing pad can separate objects from each other to prevent objects from colliding with each other due to bumps when people move, causing damage to the objects, thereby improving the use effect of the plastic bag. However, the buffer support structure and the partition structure used in the above technical solution are in an unchanged state, so they take up a lot of space when stacked for storage. At the same time, the protective structure and the dividing pad at the bottom cannot be flattened for storage, which reduces the storage capacity and reduces the flexibility of storage.

DETAILED DESCRIPTION

[0022] In order to more clearly illustrate the overall concept of the present invention, a detailed description is given below in the form of examples in conjunction with the accompanying drawings.

[0023] The examples are as follows:

[0024] The utility model provides Figure 1-4 A biodegradable bio-based material plastic bag shown includes a plastic bag body 1, and an inflatable partition protection mechanism is provided inside the plastic bag body 1;

[0025] The inflatable partition protection mechanism comprises a first filling slot 2 opened at the bottom of the plastic bag body 1, a first air cushion 3 is arranged on the inner wall of the first filling slot 2, a plurality of partition pads 4 are fixedly arranged at equal distances on the bottom of the inner wall of the plastic bag body 1, a second filling slot 5 is opened on the inner wall of each partition pad 4, a second air cushion 6 is arranged on the inner wall of each second filling slot 5, a first connecting pipe 7 is inserted at equal distances at the lower end of one side of the plastic bag body 1, and one end of each first connecting pipe 7 passes through the inner wall of the plastic bag body 1 and the inner wall of the partition pad 4 and each second air cushion 6. The inner wall of the cushion 6 is interlaced and connected, and the lower end of the outer wall of the plastic bag body 1 is equidistantly interlaced with an air inlet pipe 8. By arranging a first connecting pipe 7 in the second air cushion 6, and then connecting the first connecting pipe 7 with the air inlet pipe 8, when the first air cushion 3 is inflated, it is prevented from pulling between the second air cushion 6 and the air inlet pipe 8, resulting in a break at the connection. The first connecting pipe 7 plays a role in extending the buffer. At the same time, the entire plastic bag is made of wood fibers in platycodon and plant branches. When it needs to be processed later, the plastic bag is easy to degrade and not easy to pollute the environment, which plays an environmental protection role.

[0026] Furthermore, one end of one of the air intake pipes 8 is connected to the inner wall of the first air cushion 3 through insertion, and the inner walls of the other multiple air intake pipes 8 are connected to the inner wall of each first connecting pipe 7 respectively.

[0027] A sealing plug 9 is fixedly provided on one side of the outer wall of each air inlet pipe 8, and the outer wall of one end of each sealing plug 9 is respectively connected with the inner wall of each air inlet pipe 8. When the first air cushion 3 and the second air cushion 6 need to be inflated, the sealing plug 9 can be pulled out and air can be blown directly into the air inlet pipe 8. Each of the second air cushions 6 is separately provided with an air inlet pipe 8. The corresponding separation pad 4 can be supported as needed, so that the space size of the separation area can be adjusted according to the size of the carried items while separating.

[0028] Furthermore, through grooves 10 are provided on both sides of the top of the plastic bag body 1 , and the outer walls at both ends of the plastic bag body 1 are sleeved with inflatable cushions 11 , and the outer wall of each inflatable cushion 11 is respectively interlaced and connected with the inner wall of each through groove 10 .

[0029] A conduit 12 is inserted into one side of the inner wall of one of the inflatable cushions 11, and the outer wall of one end of the conduit 12 passes through the inner wall of the plastic bag body 1 and is inserted and connected to the inner wall of the other inflatable cushion 11. The conduit 12 passes through the inner wall of the bag opening area of ​​the plastic bag body 1, so that the bag opening area has a certain protrusion, which makes it more convenient to open the bag opening later.

[0030] A second connecting tube 13 is inserted into one side of the outer wall of one of the inflatable cushions 11, and an extrusion type air bag 14 is fixedly provided at one end of the second connecting tube 13, and the inner wall of the second connecting tube 13 is communicated with the inner wall of the extrusion type air bag 14. After the inflatable cushion 11 is inflated by the extrusion type air bag 14, the extrusion type air bag 14 will hang down along the second connecting tube 13 to the edge of the inner wall of the plastic bag body 1, so that it does not hinder the user's use, and before the plastic bag is not used, the inflatable cushion 11 is not inflated and can be folded and stored together with the plastic bag body 1, without taking up much space.

[0031] Working principle: When using the biodegradable bio-based material plastic bag in this design, firstly, the conduit 12 connecting the two inflatable cushions 11 needs to be inserted at the edge of the bag opening of the plastic bag body 1, so that the two inflatable cushions 11 are connected. When placing fragile items, the user can blow air through the air inlet pipe 8, so that the first filling slot 2 is inflated and supported by the first air cushion 3, and at the same time, the second air cushion 6 in the second filling slot 5 is also blown up, so that the partition pad 4 stands upright inside the plastic bag body 1, dividing the inside into multiple areas, so that fragile items are not easily damaged by collision, and at the same time, the bottom is also supported by buffering, so that large items or objects can be placed later. When there are many items, the sealing plug 9 is opened to discharge the air in the first air cushion 3 and the second air cushion 6, and the plastic bag is restored to the state of an ordinary plastic bag, which is convenient for placing more items. The structure is not easily crushed, and the flexibility of the plastic bag is improved. When the user lifts the plastic bag body 1, the user passes the finger through the through groove 10 to lift it. When the items carried are heavy, the extrusion air bag 14 is pressed to inflate the inflatable cushion 11 through the second connecting tube 13, and the inflatable cushions 11 at both ends are inflated through the transmission of the conduit 12. The user touches the inflatable cushion 11 with his hand and then lifts the plastic bag to relieve the pressure and make it more comfortable.
