Description

Technical Field

[0001] The present application relates to the technical field of Christmas tree decorations, and in particular to a modular Christmas tree. Background Art

[0002] A Christmas tree is an evergreen tree decorated with candles and ornaments. It is one of the important elements of Christmas. Currently, there are two main types of Christmas trees on the market: wooden and plastic.

[0003] Most wooden Christmas trees are made by cutting trees and then processing and modifying them; most plastic Christmas trees are made by injection molding PVC materials; in actual use, the production of wooden Christmas trees requires felling trees, and the trees themselves are large and difficult to transport, and the made Christmas trees can only be used for a short period of time and cannot be recycled for a long time, making them inconvenient to use. Plastic Christmas trees made of PVC materials are limited by the fact that PVC materials themselves are corrosion-resistant and difficult to degrade in nature, causing obvious environmental pollution and being unfavorable to use; therefore, paper Christmas trees with the characteristics of recycling, energy saving and environmental protection, light weight, low cost, and easy transportation came into being.

[0004] Most existing paper Christmas trees are made by gluing multiple cardboards into a tree-like structure through a glue layer. The gluing process is troublesome, and when the Christmas tree needs to be disassembled for storage, the glue layer at the connection of the cardboards needs to be destroyed first. Since the structure of the cardboard itself is relatively fragile, the cardboard is easily damaged when the glue layer is destroyed, resulting in the inability to reassemble the cardboard into a Christmas tree later, which is inconvenient to use. Utility Model Content
