Description

Technical Field

[0001] This utility model relates to the field of cardboard box technology, specifically to a stackable, weight-bearing cardboard box. Background Technology

[0002] Stackable cardboard boxes are made by stacking the outer box on top of the inner box. They are equivalent to double-layered cardboard boxes, except that the opening method is different. Currently, stackable cardboard boxes are made entirely of paper materials, and their load-bearing capacity is limited. Once the weight is exceeded, they will be damaged or the bottom will be exposed.

[0003] Therefore, in order to correct the above-mentioned defects, we propose a stacked, weighted cardboard box. Utility Model Content

[0004] The technical problem solved by this utility model is to provide a stacked, weighted cardboard box.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a stackable weighted cardboard box, comprising an inner box and an outer box, the outer box being inserted upside down into the inner box, the outer box having no bottom, and the inner box having no top. The inner box includes a box bottom and four box sides. When the box bottom and four box sides of the inner box are unfolded, they form a cross shape. The box bottom is provided with a plurality of crisscrossing plastic rigid strips I, and the four box sides are provided with a plurality of plastic rigid strips II.

[0006] Furthermore, both sides of the box bottom have extended edges, the width of which is the same as the thickness of the box edge.

[0007] Furthermore, a magnetic ring is embedded in the extended edge, and iron blocks are provided on both sides of the box edge at the front and rear of the box bottom. When the four box edges are closed, the magnetic ring and the iron blocks attract each other.

[0008] Furthermore, the second plastic rigid strip is connected to its corresponding first plastic rigid strip by a fabric tape.

[0009] Furthermore, the bottom of the box and the four sides of the box are provided with through holes for the plastic rigid strip one and plastic rigid strip two to pass through, respectively.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: The stackable cardboard box of this utility model adopts a combination of paper material and rigid plastic, which improves the load-bearing capacity of the stackable cardboard box. In addition, the rigid plastic between the box side and the box bottom adopts a soft connection to ensure that the box side and the box bottom will not detach. Furthermore, the four box sides can be spread out to facilitate the placement of objects into the inner box, avoiding the inner box from cracking when the size of the object is the same as the size of the inner box.

Detailed Implementation

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0013] This utility model provides a technical solution: Please see Figure 1-4 A stackable, weight-bearing cardboard box includes an inner box 1 and an outer box 2. The outer box 2 is inserted upside down into the inner box 1. The outer box 2 has no bottom, and the inner box 1 has no top. The inner box 1 includes a bottom 11 and four sides 12. When the bottom 11 and the four sides 12 of the inner box 1 are unfolded, they form a cross shape. The bottom 11 has several crisscrossing plastic rigid strips 16, and the four sides 12 have several plastic rigid strips 17. The four sides 12 are not fixedly connected to each other, that is, the inner box 1 can be unfolded to facilitate the placement of objects on the bottom 11. After the objects are placed, the four sides 12 are closed. Due to the combination of paper material and rigid plastic, the load-bearing capacity of the stackable cardboard box is improved.

[0014] To ensure a tighter fit when the four sides 12 of the box are closed, each side of the side 12 located on the left and right of the bottom 11 of the box has an extension edge 13. The width of the extension edge 13 is the same as the thickness of the side 12. That is, when closed, the extension edge 13 of the side 12 located on the left and right of the bottom 11 of the box fits perfectly against the edges of the other two sides 12. A magnetic ring 14 is embedded in the extension edge 13. Iron blocks 15 are provided on both sides of the side 12 located before and after the bottom 11 of the box. When the four sides 12 are closed, the magnetic ring 14 and the iron blocks 15 attract each other. After closing, the magnetic attraction method is used to make the four sides 12 tightly connected to prevent them from coming apart and to facilitate the stacking of the outer box 2.

[0015] To make the connection between the box edge 12 and the box bottom 11 more stable, the second plastic rigid strip 17 and its corresponding first plastic rigid strip 16 are connected by a cloth tape 18. The rigid plastic between the box edge and the box bottom uses a soft connection to ensure that the box edge and the box bottom will not detach.

[0016] The bottom 11 and the four sides 12 of the box are provided with through holes for the plastic rigid strip 16 and plastic rigid strip 2 17 to pass through.

[0017] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
