Description

Technical Field

[0001] The utility model relates to the technical field of paper boxes, in particular to a paper box which is easy to open. Background Art

[0002] Paper packaging is the most widely used type of packaging industry products. Cartons are the main form of transportation packaging, and cartons are widely used as sales packaging for various products such as food, medicine, and electronics. With the changes in transportation methods and sales methods, the styles of cartons and cartons are becoming more and more diversified. Almost every new type of non-standard carton is accompanied by a set of automated equipment, and the novel-shaped carton itself has also become a means of product promotion. Carton packaging is largely used to promote and beautify products with its exquisite shape and decoration to improve the competitiveness of products. Since the shape and structural design of the carton are often determined by the shape characteristics of the packaged goods, there are many styles and types, including rectangular, square, polygonal, special-shaped cartons, cylindrical, etc. After the product is placed in the conventional packaging carton, it is sealed with tape, and the tape needs to be torn off with scissors or other sharp tools, or the tape can be torn off directly.

[0003] In the prior art, the paper box needs to be opened by tearing off the tape. However, when tearing off the tape, the tape is easy to damage the paper box, resulting in a shortened life of the paper box and inconvenience for repeated use. Therefore, we propose a paper box that is easy to pull open. Utility Model Content

[0006] Preferably, a positioning rod is provided on the surface of the slide rail, and the positioning rod is slidably connected to the slider. The provided positioning rod can limit the slider and improve the stability of the slider when it moves.

[0007] Preferably, protective frames for supporting the connecting frame are symmetrically arranged on both sides of the surface of the box body, and the arranged protective frames can support and protect the connecting frame.

[0008] Preferably, a pressing plate is provided on the surface of the connecting frame, and a through hole for the cutting blade to pass through is opened on the surface of the connecting frame. The provided pressing plate can protect the cutting blade and avoid scratching the staff.

[0009] Preferably, a slot is provided on the surface of the cover plate, and a pull rod is rotatably connected to the surface of the slot via a bearing, and the provided pull rod facilitates opening the cover plate to both sides.

[0010] Preferably, a tape is provided on the surface of the cover plate, and the tape can be provided to close the two cover plates.

[0011] Compared with the prior art, the advantages and positive effects of the utility model are:

[0012] 1. The utility model provides a paper box that is easy to open. By setting a cutting blade, when cutting the tape, the cutting blade is driven to move by pushing the connecting frame, thereby cutting the tape and disconnecting the tape. At this time, the cover plate can be easily opened.

[0013] 2. The utility model provides a paper box that is easy to open. By cutting the tape, there is no need to peel the tape off the cover plate, thereby avoiding damage to the cover plate, so that the paper box can be used multiple times, improving the use effect of the device.
