Combined insulation box based on inner and outer box bodies

Abstract

The invention provides a combined insulation box based on inner and outer box bodies. The combined insulation box comprises the outer box body and the inner box body, wherein the inner box body is provided with two extending lug parts, each extending lug part is provided with an inner connecting part, spaces between the two inner connecting parts can be connected with each other, when the inner box body is assembled in the outer box body, the extending lug parts at the two ends can both penetrate through strip holes of a corresponding first panel and a corresponding second panel, and after thefirst panel and the second panel are in butt joint to cover an outer box accommodating cavity, the two extending lug parts are connected with each other through the inner connecting parts at the outer sides, far away from the outer box accommodating cavity, of the first panel and the second panel. According to the combined insulation box, linkage opening and closing are achieved among the inner box body and the panels for covering and closing at the upper end of the outer box body and the extending lug parts, so that the opening and closing operation convenience of the combined insulation boxis improved on the premise of ensuring the insulation effect on the inner box body.

Description

technical field [0001] The invention relates to the technical field of packaging boxes, in particular to a combined insulated box based on inner and outer boxes. Background technique [0002] With the rapid development of the Internet and the popularization of people's consumption behavior on the Internet, the demand for cold chain transportation and home delivery transportation in the fresh food and food industry is increasing day by day, and the usage of related cold chain transportation packaging and packaging materials is also increasing rapidly. [0003] At this stage, in order to achieve better thermal insulation effect in cold chain transportation and home delivery incubators, some merchants improve the thermal insulation effect by nesting multiple boxes, such as built-in foam boxes, and the outer layer is cardboard boxes, but there is no linkage between the inner and outer boxes , In the process of opening and closing, it is necessary to open each layer of packing bo...
