Description

Technical Field

[0001] The utility model relates to the field of paper box processing, in particular to a self-standing paper box with a stable structure. Background Art

[0002] A self-supporting carton is a special carton structure that can stand on its own without the need for additional support. This carton design usually achieves this self-supporting function through its unique bottom structure and reinforced side walls. Self-supporting cartons are widely used in many fields, such as packaging for food, medicine, cosmetics and other products.

[0003] After searching, the applicant found that a Chinese patent disclosed "a corrugated paper box", and its publication (announcement) number is "CN214397688U". This patent mainly relates to the field of transport containers, and in particular to a corrugated paper box, which includes a bottom sheet and multiple side panels, and the multiple side panels are all arranged on the side walls of the bottom sheet. Several side panels are provided with clearance grooves, and the clearance grooves extend along the rotating shafts of the side panels. The inner wall of each clearance groove is inclined, and the width of the clearance groove gradually decreases along the depth direction of the clearance groove. This application has the effect of reducing the processing allowance of the corrugated paper box and reducing the production cost of the corrugated paper box. However, the above-mentioned device has poor stability during use, and the surface of the carton is prone to wrinkles when subjected to a certain degree of compression. In addition, it is not convenient to separate the base and the box body of the carton during operation, which greatly increases the space occupied by the device. Utility Model Content
