Abstract

The invention discloses a self-heating device for metal canned beverage and food. The self-heating device comprises a metal inner can for storing foods, an outer can body, an intelligent base, a heating bag, an easily-torn water bag and a pull rope, and is characterized in that a can bottom made from a metal material is arranged at the bottom of the outer can body; the outer can body is made from a composite paper tube; the intelligent base is arranged inside the outer can body; the metal inner can is arranged on the chassis of the intelligent base; the easily-torn water bag and the heating bag are arranged below the chassis; the easily-torn water bag is connected with the pull rope; the pull rope reaches the chassis of the intelligent base after bypassing the lower surface of the easily-torn water bag and extends to the upper surface of the metal inner can via the sidewall of the metal inner can. According to the self-heating device for the metal canned beverage and food, the easily-torn water bag is convenient to tear and effortless; the pull rope bypasses a triangular reinforcing rib; water in the water bag is totally extruded out and has full reaction with the heating bag; the problems that the pull rope is broken, but the water bag is not opened or the water bag is not heated enough are prevented; therefore, the self-heating device is applicable to various canned foods which need to be heated, and is especially applicable to the packaging for soup, porridge, coffee and the like.

Description

technical field [0001] The invention relates to the technical field of food packaging cans, in particular to a self-heating device for metal canned food and drinks. Background technique [0002] With the acceleration of the pace of life, the consumption of convenience food has grown rapidly, and a wide variety of fast food has appeared on the market. Some convenience foods need to be heated to maintain their taste, such as soup, salty porridge, coffee, etc. Rapidly heating food on the Internet has become an urgent problem to be solved.

A self-heating device for metal canned food and drink disclosed in a Chinese patent, the application number is CN201520785589.0, which discloses a self-heating device for metal can...

AI Technical Summary

Problems solved by technology

However, in this kind of self-heating tank, the metal inner tank is easy to loosen during transportation. When it hits the top of the outer tank, the air in the outer tank will flow into the space where the self-heating package is located, causing oxidation of the heating package, and even tearing of the water bag. Crack holes, affecting the heating effect

Or the metal inner tank is loose during the bumpy journey, and the soup in it is easy to spill, which will cause problems such as dirty clothes
