Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of paper plates, and specifically relates to an environmentally friendly degradable paper plate structure. Background Art
[0002] A paper plate is a lightweight and disposable tableware, usually made of white cardboard made of chemical wood pulp by pressing with a plate rolling machine. Its shape is similar to that of plates made of other materials, but it is much lighter. Due to its lightness and environmental friendliness, paper plates are widely used in various occasions, such as families, schools, outdoor activities, etc.
[0003] However, the current environmentally friendly degradable paper plate structure still has disadvantages in actual use. The more obvious one is that during the stacking and transportation process of paper plates, the paper plates are prone to slipping, and the limiting ability between paper plates is poor, which is not convenient for the stacking and transportation of paper plates. Moreover, when taking the stacked paper plates, since the paper plates are relatively thin, it is easy to directly grab the inside of the paper plates to take them, which is likely to cause pollution to the paper plates. For this reason, we propose an environmentally friendly degradable paper plate structure. Summary of the Utility Model

A support pad 150 is fixedly connected to the bottom of the inner cavity of the plate body 100. A connecting groove 160 matching the support pad 150 is opened at the bottom of the plate body 100. The support pad 150 cooperates with the connecting groove 160 to realize the connection of two plate bodies 100.
[0025] Please refer to Figures 1-3 , the connecting member includes two fixing blocks 130, and the two fixing blocks 130 are fixedly connected to both ends of the outer side wall of the plate body 100, and the conical columns 140 are supported by the fixing blocks 130.
[0026] Please refer to Figures 1-3 , a conical column 140 is fixedly connected to the top of the fixing block 130, a through groove 131 is opened at the bottom of the fixing block 130, the through groove 131 is used in cooperation with the conical column 140, and the conical column 140 is connected to another conical column 140 through the through groove 131.
