Description

Technical Field

[0001] The utility model belongs to the technical field of paper plate storage, and specifically relates to a paper plate storage device. Background Art

[0002] A paper plate is a lightweight and disposable tableware, usually made of white cardboard made of chemical wood pulp through a plate rolling machine. Its shape is similar to that of plates made of other materials, but it is much lighter. Due to its light weight and environmental protection characteristics, paper plates are widely used in various occasions. After being processed, paper plates usually need to be placed in a paper plate storage device for easy transfer and transportation.

[0003] When the existing paper plate storage device is in use, paper plates are usually stacked in a storage box. There is a lack of limitation on the paper plates. During transportation, the paper plates are prone to shaking and scattering, which affects the storage effect of the paper plates and reduces the practicability of the storage device. Therefore, we propose a paper plate storage device. Summary of the Utility Model
