Self-heating food packaging box

Abstract

The invention discloses a self-heating food packaging box. The self-heating food packaging box comprises box covers, an external box and an internal box. The internal box is placed inside the externalbox in an embedded manner from a top opening of the external box. Two positional relations of a packaging superimposed state and a heating separated state exist between the internal box and the external box. In the packaging superimposed state, the bottom of the internal box is in contact with the bottom of the external box in a superimposed manner, and both food bags and heating bags inside thepackaging box are tightly distributed inside the internal box correspondingly. In the heating separated state, the bottom of the internal box is separated from the bottom of the external box, and heating space is formed. The food bags inside the packaging box are placed inside the internal box, and the heating bags are placed in the heating space. The internal box and the external box are coveredby the box covers simultaneously. In the packaging superimposed state and the heating separated state, positional location between the internal box and the external box is achieved respectively. According to the self-heating food packaging box, the packaging volume of self-heating food is effectively reduced; carrying is convenient; operation is convenient and fast; the fabricating cost and transportation cost are saved; and the anti-deformation capacity of the packaging box is improved.

Description

technical field [0001] The invention belongs to the technical field of self-heating food packaging, in particular to a self-heating food packaging box. Background technique [0002] With the acceleration of people's life rhythm, there are more and more "fast and convenient" self-heating foods on the market. Well-known domestic and foreign brands have launched a series of products such as self-heating rice, self-heating hot pot, self-heating rice noodles, and noodles. There are also a variety of self-heating food packaging designs, but the common problems are that the packaging is too large, contains accessories such as water bags, which makes it too heavy and inconvenient to carry, too much internal space makes it easy to squeeze and deform during transportation, and has a low safety factor. low-level defects. [0003] Self-heating rice lunch boxes on the market generally have a height of 8-9cm, while self-heating hot pots mostly adopt a circular design, and the height of t...
