Embodiment approach

[0029] As an embodiment of the present invention, No. 2 airbag 215 is installed on the opposite surfaces of No. 1 saw tooth 211 and No. 2 saw tooth 212; 216 communicates with two No. 2 airbags 215 through No. 1 channel 217 respectively; By the tight fit between No. 2 airbag 215 and the tower-like projection 224, further prevent the plugging and disengagement of left box cover 21 and right box cover 22; During operation, the two No. 2 airbags 215 installed on the opposite surfaces of the No. 1 sawtooth 211 and the No. 2 sawtooth 212 are squeezed by the No. 3 sawtooth 221 with tower-shaped protrusions 224 on the surface, so that the two No. 2 airbags 215 The gas inside is pressurized and flows along the No. 1 channel 217 to the No. 1 chamber 216. The gas pressure inside the No. 1 chamber 216 increases due to the increase of gas. The bump 224 increases the surface roughness of the No. 4 sawtooth 222, so that the fit between the No. 4 sawtooth 222 and the No. 2 airbag 215 is tight...

Abstract

The invention belongs to the technical field of packaging boxes, particularly relates to a paper box and a paper box blank. The paper box includes a box body, a box cover, handles and the paper box blank. The box body is of a hollow cuboid structure, and the paper box blank is imbedded into the box body; the box cover includes a left box cover and a right box cover, the box cover is installed at the top end of the box body, and the handles are installed on the left box cover and the right box cover; serrations and No.1 air bags filled with water-absorbing powder are arranged at connecting positions of the box cover; and the paper box blank includes a contact layer, a buffer layer and a heat insulation layer from the inside to outside, and the contact layer is made of food-grade film and can be replaced. The paper box can be used as a packaging box for take-out, has good airtightness and heat insulation, and can be reused many times, resources are saved, and the paper box can be naturally degraded after the service life is over to avoid damage to the environment.

Description

technical field [0001] The invention belongs to the technical field of packaging boxes, in particular to a carton and a carton blank. Background technique [0002] At present, plastic packaging bags or cartons are mainly used to deliver food in the market, but plastic packaging boxes cannot be naturally degraded by the environment or take a long time to degrade, and are prone to white pollution. Therefore, from the perspective of protecting the environment and reducing white pollution, using paper The packaging box is a better choice. However, the paper packaging boxes often used in the market are mostly bonded and fixed by chemical adhesives, which have low structural strength, are inconvenient to use, and are easy to damage food, and the reuse rate is low. [0003] In the Chinese invention patent (application number: 2018100786794), the present invention discloses a carton, which includes: a carton body consisting of a bottom panel, a front panel, a rear panel, a left pan...
