High-strength compression resistant carton

Abstract

The invention relates to a high-strength compression resistant carton. Upper coves which are bent in opposite directions are arranged on the top of a carton body, lower bases which are bent in opposite directions are arranged at the bottom of the carton body, supporting plates are attached to the inner side walls of the carton body, corner frames are attached to the inner portions of the vertical corners of the carton body, a rectangular frame is arranged around the supporting plates, and at least two longitudinally-parallel supporting rods are arranged in the frame. Each corner frame is of a perpendicular L shape, and the height of each corner frame is consistent with the height of the carton body. The supporting plates are attached to the four inner side walls of the carton body respectively. The two horizontal sides of each supporting plate are connected with one side of one corresponding corner frame and one side of another corresponding corner frame respectively. The top of the carton body can be covered with the upper covers in a rotating mode, the top of the carton body can be covered with the upper covers on the two sides, and the lower bases at the bottom of the carton body are connected with each other in opposite directions in a bent and butt joint mode. The high-strength compression resistant carton is simple in structure, convenient to use and high in compression resistance, the weight of the carton body is low, the supporting plates and the corner frames can be supported against the inner portion of the carton when the carton is used and can be taken out of the carton when the carton is not used, and the carton can be conveniently folded and stored.

Description

technical field [0001] The invention relates to a carton capable of resisting high-strength pressure, belonging to the field of cartons. Background technique [0002] Carton is one of the most commonly used packaging supplies. Cartons are also popular and welcomed by people because of their low price, environmental protection, and recyclability. However, cartons also have certain defects. On the premise of ensuring a relatively low price, cartons The compressive performance of the carton will be reduced. To ensure good compressive performance, the quality of the carton board needs to be improved. If the raw material is considered, the content of high-quality fiber in the carton board needs to be increased. However, from the perspective of a reasonable distribution of national resources As mentioned above, high-quality fiber resources are used to make cartons, which is an unreasonable resource layout.

[0002] Carton is one of the most commonly used packaging supplies. Cartons are also popular and welcomed by people because of their low price, environmental protection, and recyclability. However, cartons also have certain defects. On the premise of ensuring a relatively low price, cartons The compressive performance of the carton will be reduced. To ensure better compressive performance, the quality of the carton board needs to be improved. Considering the raw materials, it is necessary to increase the content of high-quality fiber in the carton board. However, from the perspective of a reasonable distribution of national resources As mentioned above, high-quality fiber resources are used to make cartons, which is an unreasonable resource layout. High-quality fiber resources must be used to make more high-quality daily necessities. Carton boards mainly use secondary fiber resources. Such fibers Usually the length is short, and the carton board is easily deformed under pressure. The traditional method is to thicken the thickness of the carton board to enhance the compressive strength of the carton, but the weight of the carton increases after the thickness is increased, and the thickness increases. Finally, the difficulty of processing carton board into cartons also increases, increasing the difficulty of carton board in bending and binding

At present, there is no better way to solve the problem of enhancing the compressive strength of cartons.
