Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of plastic bags, especially to a plastic bag with sealing structure. BACKGROUND

[0002] Plastic bags are common household items used to store other items. They are found in supermarkets, traditional markets, department stores, warehouses, and landfills. Plastic bags are essential in daily life and are often used to store other items. They are widely used because of their low cost, light weight, large capacity, and easy storage. However, the existing plastic bags have certain drawbacks when in use. When we need to seal and store items, we usually tie the handles of the plastic bag tightly to isolate air,

[0003] The existing plastic bag with sealing structure only relies on a single sealing method, such as simple folding or simple buckling. It is difficult to ensure that the bag opening completely fits. Compared with the multi-step sealing mechanism, the single-step sealing is more likely to produce gaps at the sealing place. These gaps may allow external air, dust, and moisture to easily enter the bag. For items that need to be strictly sealed and stored, this will affect the quality and performance of the items. SUMMARY

[0004] To solve the above technical problems, the utility model provides a plastic bag with sealing structure.

[0005] The utility model adopts the following technical scheme: a plastic bag with sealing structure, including plastic bag body, the top of plastic bag body is fixedly connected with pull handle, the top of plastic bag body is fixedly connected with connecting bag mouth one, the top of plastic bag body is fixedly connected with connecting bag mouth two, the inside of connecting bag mouth one is fixedly connected with magic tape one, the right end of magic tape one is bonded with magic tape two, magic tape two is fixedly connected in the inside of connecting bag mouth two, the inside of plastic bag body is fixedly connected with sealing protruding block, the inside of plastic bag body is provided with sealing recess, the top of plastic bag body is fixedly connected with installation buckle, the top is fixedly connected with connecting buckle.

[0006] Through the above technical scheme, connecting bag mouth one and connecting bag mouth two realize sealing through magic tape one and magic tape two. The bonding method of magic tape is simple and fast, and does not require additional tools. Users can easily open and close the bag opening, making it convenient to take and place items in the bag.

[0007] As a further improvement of the above scheme, the number of pull handles is set to two, and the two pull handles are distributed symmetrically left and right of the plastic bag body.

[0008] As a further improvement of the above scheme, the sealing protrusion is inserted in the sealing groove inside the plastic bag body.

[0009] Through the above technical scheme, the sealing protrusion can cooperate with the sealing groove opened in the plastic bag body to perform the first step of sealing.

[0010] As a further improvement of the above scheme, the magic tape is fixedly connected to the left end of the connecting bag opening two, and the right end of the connecting bag opening one is in surface contact with the left end of the connecting bag opening two.

[0011] As a further improvement of the above scheme, the number of installation buckles is set to two, and the two installation buckles are symmetrically distributed forward and backward with the plastic bag body as the center.

[0012] As a further improvement of the above scheme, the number of connecting buckles is set to two, and the two connecting buckles are symmetrically distributed forward and backward with the plastic bag body as the center.

[0013] Compared with the prior art, the utility model has the beneficial effects that:

[0014] The magic tape sealing opening of the connecting bag opening one and the connecting bag opening two can prevent the falling of the articles in the bag and the entry of dust, sundries and the like from the outside into the bag, on the other hand, the sealing protrusion inside the plastic bag body is inserted in the sealing groove, and the structure further enhances the sealing effect, can better prevent the articles in the bag from being damp, oxidized or leaked, is very favorable for some articles which need good storage conditions, and increases the sealing property when the plastic bag body is connected.

[0015] The plastic bag body is provided with two installation buckles and two connecting buckles on the top, and is symmetrically distributed forward and backward with the plastic bag body as the center. The buckle structure of the symmetric distribution helps to provide stable connection in some specific use scenarios, and makes the use of the plastic bag more flexible and various.
