Description

Technical Field

[0001] The utility model relates to the field of packaging equipment, in particular to a corner-opening packaging box. Background Art

[0002] Paper packaging boxes are a commonly used type of packaging tool at present. A commonly used packaging box is disclosed in the patent publication document CN214493670U. This type of packaging box is formed by folding a piece of paper multiple times. The bottom of this type of packaging box is formed by splicing and overlapping four bottom sheets. Since there is no clamping between the four bottom sheets at the bottom of this structure, when the four bottom sheets are subjected to external extrusion, the bottom formed by the four bottom sheets is squeezed open. After the bottom is squeezed open, it is very easy to take out the items in the box, resulting in the theft of the contents in the box, and there will be no corresponding traces left after the bottom is squeezed open. Summary of the Utility Model

[0003] In view of the above problems, the utility model provides a corner-opening packaging box. A clamping hole is opened on the second bottom sheet of this type of packaging box, and two mutually approaching embedding parts are arranged on the fourth bottom sheet. Through the cooperation of the embedding parts and the clamping holes, the compressive performance of the bottom of the entire packaging box is improved, ensuring that the bottom of the packaging box will not be squeezed open.

[0028] In order to make the above objects, features, and advantages of the present utility model more obvious and understandable, the following will describe in detail the specific implementation manners of the present utility model with reference to the accompanying drawings.

[0029] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific implementation manners disclosed below.

[0030] As shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 shown, a corner-opening packaging box includes a box body part and a box cover part. The box body part is a box body part in the shape of a square cylinder. The box cover part is arranged at one end of the box body part. It further includes a first bottom piece 13, a second bottom piece 14, a third bottom piece 15, and a fourth bottom piece 16. The first bottom piece 13, the second bottom piece 14, the third bottom piece 15, and the fourth bottom piece 16 are respectively arranged along the four peripheries of the box body part. The second bottom piece 14 is provided with an engaging hole 1401. The fourth bottom piece 16 is provided with an embedding part 1602. There are two embedding parts 1602, and a deformation-adapting round hole 1601 is arranged between the two embedding parts 1602; the engaging hole 1401 is used for clamping and cooperating with the embedding part 1602.

[0031] In this kind of packaging box, two embedding parts 1602 are arranged on the fourth negative film 16. A deformation adaptation round hole 1601 is located between the two embedding parts 1602. After being extruded, the two embedding parts 1602 will move closer to each other, and the deformation adaptation round hole 1601 will shrink. When the two embedding parts 1602 are in a natural state without force, the width of the two embedding parts 1602 is greater than the width of the engaging hole 1401. When it is necessary to insert the embedding parts 1602 into the engaging hole 1401, the two embedding parts 1602 are pressurized so that the two embedding parts 1602 move closer to each other. After the two embedding parts 1602 are completely inserted into the engaging hole 1401, the external force on the embedding parts 1602 is removed. The two embedding parts 1602 respectively clamp the two sides of the engaging hole 1401, so that the embedding parts 1602 are clamped in the engaging hole 1401. In this way, it is equivalent to clamping the second negative film 14 and the fourth negative film 16 together, thus forming the compressive resistance of the entire bottom, ensuring that the entire bottom will not be squeezed open, improving the safety of the items in the packaging box, and reducing the probability of theft of the items in the packaging box.
