Collapsible hard box

Abstract

The invention provides a foldable hard packaging box. The foldable hard packaging box comprises an outer packaging box, an inner container box and a supporting frame, wherein a front inner-side face plate, a bottom face plate, a rear face plate and a top face plate are folded along creases so as to form the outer packaging box, the two ends of the outer packaging box are open, the inner container box is composed of an upper face plate, a lower face plate and lower folded plates, the two ends of the inner container box are open, the two lower folded plates are folded towards the same side along creases so that the inner container box can be in a plane state or in a stereoscopic state, the supporting frame is composed of a top plate, a bottom plate and two side plates, the supporting frame is unfolded, the inner container box is sleeved with the unfolded supporting frame, and the outer packing box is closed. The foldable hard packaging box is used for solving the problem that an existing hard packaging box cannot be folded and occupies too much space in the process of transportation and storage, and effectively improving the utilization rate of transportation and storage space on the premise that the packaging protecting effect and the attractiveness of the packaging box are not influenced.

Description

technical field [0001] The invention relates to the field of packaging and printing, in particular to a foldable rigid packaging box, which is used to solve the problem that the current rigid packaging box cannot be folded and takes up too much space in the process of transportation and storage, without affecting the packaging protection effect and packaging On the premise of improving the aesthetics of the box, it can effectively improve the utilization efficiency of transportation and storage space. Background technique [0002] Packaging boxes are often used for the outer packaging of food, cosmetics, and stationery decorations. At present, there are mainly two types of packaging boxes on the market, one is foldable and the other is non-foldable. The foldable packaging box can change the packaging box from a three-dimensional state to a flat state, or change the packaging box from a flat state to a three-dimensional state by folding one or several parts. The non-foldable...

Problems solved by technology

[0003] The advantages of non-foldable packaging boxes are that they can be made of thicker materials, can withstand greater external impact, have good packaging protection effects, good box material stiffness, and better three-dimensional molding effects; its disadvantage is that after the box is formed It cannot be folded, and cannot be reduced in size during storage and transportation, takes up a lot of space, and has low space utilization efficiency, which will increase transportation and storage costs

[0004] In order to solve the aforementioned disadvantages of non-foldable packaging boxes, a foldable packaging box is designed. The advantage of the foldable packaging box is that its appearance can be changed by folding. After the packaging box is produced, it can be folded into a flat state for storage and transportation. Reduce occupied space, improve space utilization efficiency, and reduce transportation and storage costs; its disadvantage is that it is limited by the box-shaped folding structure, it is difficult to use thicker materials, and the packaging protection effect and the three-dimensional molding effect of the packaging box are poor
