Description

Technical Field

[0001] The utility model relates to the technical field of cartons, and more specifically to a carton with a tape-free snap closure. Background Art

[0002] A carton is a container used for packing and transporting items, usually made of folding cardboard or corrugated cardboard. They can have different sizes, shapes and thicknesses to meet the packaging needs of various goods. Cartons are both environmentally friendly and economical because they can be reused and are easily recyclable. Cartons are commonly used to protect goods from damage during transportation and storage.

[0003] For example, a kind of drop-resistant carton with the prior art publication number of CN218173129U. In this utility model, corner seats are provided at the top corners of the carton. When the carton falls to the ground, the corner seats play a protective role for the top corners of the carton, effectively avoiding damage to the carton when it falls; the first fixing plate is hinged to the third fixing plate, and after the first fixing plate is fixed to the carton body, it will not affect the opening and closing of the carton, which is convenient to use.

[0004] However, the above prior art still has the following problems when in use: when the carton is sealed, usually the cardboard is first folded into the interior of the carton body, and then tape is used to bond two adjacent cardboard pieces to the carton body for sealing. However, when the carton is reused, tearing the tape will cause damage to the surface of the carton, which will not only reduce the strength and service life of the carton, but also increase the use cost. Based on this, the utility model provides a carton with a tape-free snap closure and low use cost. Summary of the Utility Model
