Description

Pull-up quick-assembled storage box

technical field

The invention relates to a technology related to a paper-made accommodating box, which can quickly assemble the accommodating box in a pulling manner, and can also be disassembled into a flat state, and has the advantages of a reinforced structure.

Background technique

As shown in Figure 1, in order to print exquisite patterns, the paper quality used in the general paper fine decoration box is relatively insufficient, and it is easy to deform when holding relatively heavy items. Due to the lack of strength, the industry uses a thicker paper inner box 101 to line the inner layer of a delicate outer box 102 . When combining, the inner box 101 must be adhered to the top of the outer box 102 before the walls around the two are erected, that is, in the state of cardboard, and then the outer box 102 is used to make a plurality of wall plates erect around the bottom plate. The three-dimensional shape of the accommodation space. However, such a reinforced fine-package accommodating box cannot be folded back to a flat shape after being fixed, requiring a large storage space and relatively high transportation costs.

In addition, as shown in FIG. 2, JP 200043846 is formed by cutting a piece of cardboard and then folding it as a whole. The accommodating box 103 after folding and combining has a double-layer bottom plate 104 and a double-layer wall plate 105. Of course, the accommodating box has The step of sticking and fixing can be omitted, and the assembly time is shorter. However, since the inner layer and the outer layer are made of the same cardboard, that is, the same material, they must be made of thinner cardboard for the convenience of folding. Even if there is a double-layer structure, its There are still doubts about the lack of strength. If thicker cardboard is used, the disadvantage is that it is not easy to fold and assemble, and after folding and assembling, the buckle portion 106 in the center of the double bottom plate 104 will protrude from the position of the seam 107, which is not exquisite and beautiful; It is not easy to disassemble after being assembled into a box body.

Especially according to the general business practice, the foldable storage box is usually assembled into a flat half-folded state to facilitate storage and transportation. After being transported to the sales end, the seller will form a three-dimensional state to package the product, but the above-mentioned When the JP Patent Publication No. 200043846 is assembled, the seller must first join the two sides of the buckles 106 before assembling the container. The steps are cumbersome, which not only increases the time for consumers to wait for packaging, but also affects the service management of the operator.

In view of this, the inventor of the present invention has accumulated years of research and practical experience in related fields, and specially created a container box that can be quickly assembled by pulling, which improves the inconvenience of the existing container box, which cannot be folded and stored, and is inconvenient to assemble. , and the lack of insufficient structural strength.
