Description

Technical Field

[0001] The utility model relates to the technical field of cardboard boxes, in particular to a corrugated cardboard box with a buffer structure. Background Art

[0002] Cartons are the most widely used packaging products. According to different materials, there are corrugated boxes, single-layer cardboard boxes, etc., with various specifications and models. Commonly used cartons are three-layer and five-layer, and seven-layer is less used. Each layer is divided into lining paper, corrugated paper, core paper, and face paper. The lining and face paper are tea board paper and kraft paper, and the core paper is corrugated paper. The color and feel of various papers are different, and the paper produced by different manufacturers (color, feel) is also different.

[0003] Nowadays, cartons are widely used. Publication (announcement) No. CN214165912U discloses a corrugated cardboard box with a buffer structure, including a corrugated core layer, an inner layer is fixedly provided on the inner surface of the corrugated core layer, an outer layer is fixedly provided on the outer surface of the corrugated core layer, and a buffer layer is connected to the outer surface of the outer layer. The utility model arranges a foam board on the buffer layer, so that when the corrugated cardboard box is squeezed, the buffer layer and the outer layer slide relative to each other, thereby playing a buffering and protective role. The stability of the connection between the buffer layer and the outer layer is improved by arranging a convex block on the outer layer and a supporting groove on the buffer layer. The thermal insulation effect of the corrugated cardboard box is improved by arranging thermal insulation cotton. The wear resistance and durability of the corrugated cardboard box is improved by arranging a wear-resistant layer on the outer surface of the buffer layer. Foam balls are filled between the outer layer and the inner layer, and the foam balls are elastic. The arrangement of the foam balls improves the elasticity of the corrugated cardboard box and improves the protection of packaged items.

[0004] However, the bulge in this solution is at the bottom of the thermal insulation cotton, and the foam plate is at the top of the thermal insulation cotton. The cushioning properties of the upper and lower sides of the thermal insulation cotton are different, so that when squeezed, the upper and lower sides of the thermal insulation cotton are unevenly stressed and easily deformed, which reduces the cushioning performance. In addition, a buffer layer filled with thermal insulation cotton and foam balls is used for cushioning, and the buffering space is small and the buffering effect is limited. Utility Model Content
