Abstract

The invention provides a novel thermal insulation packing box. The novel thermal insulation packing box comprises an outer box and a box cover, wherein the outer box is made of an ECOPET sheet, the ECOPET sheet comprises an air layer on the middle part and PET surface layers on the inner side and the outer side, corrugations for anti-sliding are arranged on the outer side wall of the outer box, and an outer edge in the horizontal direction is arranged at the top of the outer box; and the box cover is made of an ECOPET sheet, the ECOPET sheet comprises an air layer on the middle part and PET surface layers on the inner side and the outer side, an exhaust hole is formed in the box cover, an inner-turned inner edge is arranged at the top of the box cover, and the box cover is connected to theouter box. According to the novel thermal insulation packing box, the problem that an existing thermal insulation box is poor in thermal insulation effect and short in thermal insulation time is wellsolved.

Description

technical field [0001] The invention relates to the technical field of thermal insulation boxes, in particular to a novel thermal insulation packing box. Background technique [0002] At present, when the existing heat preservation boxes on the market pack food, the food will generate a lot of heat and the temperature of the outer box will be too high. On the scalded surface; further, the outer box of the heat preservation box is not insulated so that the internal heat loss is serious, resulting in shortening the food heat preservation time. [0003] The comparative document CN207898116U discloses a disposable ventilating lunch box cover, including a box cover, the box cover is provided with a box cover flanging around, and the box cover is provided with air holes; in addition, the box The cover flange is also connected with the buckle cover. The buckle cover is provided with a buckle cover flange that is fastened with the box cover flange. The buckle cover can be turned u...
