Description

Technical Field

[0001] The utility model relates to the technical field of paper trays, in particular to a waterproof paper tray. Background Art

[0002] Paper plates are paper containers made of white paperboard made of chemical wood pulp and pressed by a plate rolling machine. Paper plates have the same appearance as other porcelain plates, but are much lighter. They can be used to hold Western dishes, bread, cakes, snacks, etc. However, paper plates are not suitable for holding soupy foods, and therefore do not have good waterproof properties.

[0003] After searching, the patent publication number CN216416706U is a paper tray with good anti-penetration effect, including a paper tray composed of a paper bottom plate and a paper baffle, the inner and outer surfaces of the paper bottom plate and the paper baffle are fixed with a waterproof layer by an adhesive layer, the waterproof layer is provided with a glass fiber layer, and the bottom of the paper bottom plate is provided with no less than three groups of supporting feet. In the process of implementing the above scheme, it is found that the following problems in the prior art have not been well solved: when the paper tray of the prior art is placed on the table, the support feet are used to support the paper tray. Although it can reduce the steps of dragging the paper tray on the table and prevent the friction between the paper tray and the table during the dragging process, the support feet are always exposed at the bottom of the paper tray, and the paper trays are stacked together when packaged and sold, so the exposed support feet affect the stacking operation. Therefore, it is urgent to design a waterproof paper tray to solve the above problems. Utility Model Content
