Description

Double buckle combined structure of box body and cover body formed by sheet material

This creation is about the combined structure of the box body and the cover body made of sheet materials, especially a double buckle combination structure of the box body and the cover body formed by sheet materials.

According to the plastic sheet forming method (also known as vacuum forming or lead forming), the flat plastic sheet is heated and softened, and then attached to the mold surface by vacuum suction. After cooling, it is formed, and then it is released by stamping. Cut to get the desired product. Its characteristic is that the plastic sheet is softened and adsorbed on the surface of the mold. The material at the initial contact part is the thickest after molding because the material is easy to stick to the accumulation of material. Thinning.

In the above-mentioned sheet forming method, the material in the vertical direction of the cover and the box is thinner due to the vertical stretching and extension of the material during the manufacturing process, which is easy to deform, resulting in insufficient reliability and stability after the two are closed. Most of them are disposable. They are discarded because they cannot be reused, which creates more plastic waste.

In addition, the conventional snap (buckle) structure used between the box body and the lid body is mostly provided with a corresponding inverted hook portion on the periphery of the lid body to match the ㄈ-shaped flange protruding from the periphery of the box body. There are usually two situations in the combined structure, one is that the buckle is not tight and easy to loosen, and the other is that the buckle is too tight and it is not easy to separate. In the first combination, the undercut of the cover just fits with the flange of the box, and the gripping force is not enough, and it is easy to get out of the hook due to the deformation of the whole being squeezed by the external force; the second is the undercut of the cover Due to the internal design, the box body is often loaded with improper handling methods, resulting in unhooking situations. Taking the second combination case, In the implementation, there are common structural types such as barbs and flanges, hooked protrusions and grooves. Usually the design of the barbed hook is too deep or the flange is too protruding, or the size of the hooked protrusion is significantly larger than the groove size , It will cause resistance and difficulty in the combination of this combination structure, even to complete the buckle (assembly), and the box body or the cover may be deformed; especially after the combination of funds is completed, it will also cause the box body and the cover The body is not easy to open and separate.
