A self-heating food packaging

Abstract

The invention relates to a self-heating food package. The self-heating food package comprises a first packaging bag, first space, second space, a second packaging bag, self-heating agent raw materials and a separator. The first space is formed in the first packaging bag, and water is contained in the first space. The second space is formed in the first packaging bag. The second packaging bag is arranged in the second space, and to-be-heated food is contained in the second packaging bag. The self-heating agent raw materials are arranged in the second space and are in contact with the to-be-heated food. The separator is arranged between the first space and the second space and used for disconnecting or connecting the first space with the second space as required. The use process of the self-heating food package is easy and convenient to operate; when the self-heating food package is used, the separator is operated to enable the first space to be communicated with the second space, self-heating agents and the water are rapidly combined, a heating reaction is generated, and the highest temperature can be higher than 120 DEG C. The self-heating food package is low in cost, good in effect, rapid and convenient to use, safe, environmentally friendly and easy to popularize.

Description

technical field [0001] The invention belongs to the technical field of food heating, in particular to a self-heating food package. Background technique [0002] The existing self-heating food packaging is mainly divided into three types: aluminum foil bag packaging, metal can packaging and plastic box packaging, among which aluminum foil bag packaging is the most portable. In my country's domestic civilian market, it is mainly plastic box packaging, and foreign military use aluminum foil bag packaging or metal can packaging. [0003] Whether the trigger structure of self-heating agent and water is simple and effective is an important issue that is difficult to solve in self-heating food packaging. At present, the existing trigger structures include needle type, pull rope type, self-heating sheet type, column valve type, and some packages do not have a trigger device. Then put the water on the self-heating agent. [0004] The patent number CN103385590A, named "Instant Self...
