Summary
The so-called moisture-proof bag is commonly known as an aluminum foil bag, aluminum-plastic composite bag, or vacuum bag. Its material is generally PET/AL/CPE or PET/NY/AL/CPE , among which PET—— Good printing effect, NY—— Low oxygen permeability, AL—— Strong barrier, opaque, CPE—— Used as the inner packaging layer. Adhesive: water-based adhesive ( More hygienic, environmentally friendly, no residual solvents )， This product has good anti-static, oxygen barrier, shielding, moisture-proof, and light-blocking functions, with excellent heat sealing performance. However, the current bag design is not perfect. Existing moisture-proof bags are disposable; moisture in the air can enter the bag, causing the contents to become damp and moldy. In addition, the current bags are easily contaminated, resulting in a low reuse rate. Therefore, how to design a moisture-proof bag has become a problem that needs to be solved.
Technical implementation elements: The purpose of this utility model is to provide a moisture-proof bag to solve the problems mentioned in the above background technology. To achieve the above purpose, this utility model provides the following technical solution: a moisture-proof bag, including a moisture-proof bag body and a closing device. The middle part of the moisture-proof bag body is equipped with the closing device, which fits tightly on the moisture-proof bag body; the middle of the closing device has a movable shaft fixedly connected to it; one end of the movable part is fixedly connected to the movable shaft, with a pull ring above the movable part. The upper part of the moisture-proof bag body has a bag opening fixedly connected to it. The closing device has a card slot in the middle, which is movably connected to the closing device. The inner surface of the moisture-proof bag body is provided with an oil-repellent layer with waterproof function, which fits tightly with the moisture-proof bag body. Above the oil-repellent layer is a moisture-proof layer, tightly bonded to the oil-repellent layer. Above the moisture-proof layer is a stress layer, tightly bonded to the moisture-proof layer. The fixing part has a groove inside, which fits tightly inside the fixing part. The right side of the movable part has a ring-shaped buckle fixedly connected to it, matching the size of the fixing part. Inside the movable part is a convex groove fixedly connected, leaving a certain card slot space when connected with the groove.
Compared with the prior art, the beneficial effect of this utility model is: under the joint action of the groove and the convex groove, when the convex groove connects with the groove, a certain card slot is left in the middle, allowing the fixed part and the movable part to connect with each other, then the inner card slot closes the buckle. In contrast, this design is more convenient, and the moisture-proof bag is S -shaped because it is clamped by the convex groove and the groove. The fastened S type has a certain sealing property, ensuring that external air does not enter the bag, thus preventing the contents from becoming damp and moldy. It also has waterproof capability, broadening the usage scope of the moisture-proof bag. A ring buckle is provided, matching the size of the buckle, which can connect with the buckle, allowing the moisture-proof bag to be reused. The stress layer makes the bag stronger, enabling repeated use and avoiding waste.
