Abstract
Description
Technical Field
[0001] The utility model relates to the field of packaging materials, in particular to a three-layer packaging box. Background Art
[0002] The structure of the current three-layer (or more-layer) packaging display box is roughly as shown in the patent publication document CN215555181U. In order to realize the stratification of the inner layers of the three-layer packaging box with this structure, it is necessary to place a supporting partition (numbered 4 in the figure in the document) or an inner box body (numbered 3 in the figure in the document) inside. Although placing the supporting partition or the inner box body can play the role of dividing the outer box body into layers, since the supporting partition (or the inner box body) and the outer box body are not integrated, this method of setting the supporting partition or the inner box body is prone to the situation that the supporting partition or the outer box body is lost during use, which causes many inconveniences during use. Utility Model Content
[0003] In order to solve the above problems, the present invention proposes a three-layer packaging box. The layers inside the box body can be formed by folding the pieces. The layers of the inner body are equivalent to being directly fixed to the box body. The layers will not be lost during use. The packaging box can be completely flattened for transportation when not in use, and can be opened and folded into shape when needed.
