Self-heating hot pot packaging box

Abstract

The invention relates to the technical field of food packaging, and particularly discloses a self-heating hot pot packaging box which comprises an outer shell and a cover body. A stepped flange is integrally formed on the edge of the upper end of the outer shell; an inner shell is placed in the outer shell; the side wall of the inner shell protrudes towards an inner cavity to form a plurality of reinforcing ribs; an air guide column is integrally formed at the bottom in the inner shell; an exhaust hole is formed in the top of the air guide column; an air guide cover is embedded in the upper part of the air guide column; and the cover body is buckled on the upper part of the inner shell in a close fit mode. The self-heating hot pot packaging box has the beneficial effects that the inner shell covers the outer shell, and no gap exists between the inner shell and the outer shell through matched installation of a flange clamping groove and the stepped flange, so that the sealing effect can be improved, and loss of heat generated by a heating bag is reduced; and the heat generated by the heating bag can directly enter the inner shell through a gap between the air guide cover and the air guide column, so that water and food materials are heated, the heat absorption rate is increased, and the food cooking speed is increased.

Description

Technical field[0001]The present invention relates to the field of food packaging, in particular, involving a self-heating hot pot package.Background technique[0002]With the development of social economy, people's living standards have been mentioned that self-heating food has also received a lot of promotion and application. Self-hot foods can quickly eat hot food without any cooking heating tools under any environmental conditions. With the development of self-heating food technology, it will be born in the hot pot.[0003]The food self-heating cartridge is mainly composed of an outer box, an internal box, a cover, in the outer box, cover covered in the mouth of the outer box, the bottom of the inner box, the bottom of the outer box, there is a space loading hot package, food self-heating box food The self-heating principle is to place the heating package at the bottom of the outer box, add the appropriate amount of water, and the heat package will release heat, and the heat is quic...

AI Technical Summary

Problems solved by technology

Food self-heating technology used to be a military technology in China. It was mainly used for field lunch boxes. In recent years, food self-heating technology has become popular in China. Its self-heating boxes and self-heating foods are also full of tricks and varieties, especially the self-heating of plastic products. However, some self-heating boxes have unreasonable structure, poor water vapor passage, poor self-heating effect and slow speed, especially when the outer box and inner box are too hot during self-heating, it is not suitable to move, such as moving the outer box , the inner box is easy to burn hands
