Problems solved by technology

Its shortcoming is: when edible heating, the bottom that is enclosed within the outer casing of inner layer lunch box can be heated because of heating, and is inconvenient during use, and eater is easily scalded, and lid and bottom half casing cooperate not firmly, and may burn during use. Because the lunch box was accidentally knocked over or the food in the lunch box was exposed
It is inconvenient to carry and open. The principle is that water reacts with calcium oxide to generate heat, but the water used will freeze at a temperature below zero, and cannot react with calcium oxide to generate heat. It loses its heating capacity and is not suitable for outdoor environments.

Embodiment 1

[0027] The structure of the disposable lunch box with self-heating function in this embodiment is as follows: figure 1 , 2 As shown in -8, it includes an outer box 1 made of corn oranges, an inner tank 2, an antifreeze bag 25 and a calcium oxide heating bag 24, and the inner tank 2 is contained in the outer box 1; the inner tank 2 is a double-layer box structure, and the There is an interval 23 between the layers, above the interval 23 is a food chamber 22, the top of the inner tank 2 has an openable upper cover 21, and below the interval 23 is a heating chamber 26, in which are placed an antifreeze agent bag 25 and a calcium oxide heating bag 24 , the antifreeze bag 25 and the calcium oxide heating bag 24 are provided with notches 27 on one side, and the antifreeze bag 25 and the calcium oxide heating bag 24 are fixedly connected together by a fixed point 29 on one side; the other side is respectively passed through a binding point 30 Fasten with the box body edge part of fo...

Embodiment 2

[0032] The difference from Example 1 is:

[0033] The gap 23 leaves a gap between the box body of the food cavity 22 and the heating cavity 26, so that after the steam passes through, the dishes above the soft structure upper cover 21 of the food cavity 22 in the outer box 1 is also heated at the same time. Such as figure 2 As shown, an overcoat 3 is added on the outside of the outer box 1 to reinforce the cooperation of the upper and lower halves of the outer box 1, so as to prevent the lunch box from being overturned or the food in the lunch box exposed in case of carelessness. The edge of described heating cavity 26 boxes is provided with a notch 27; during packaging, the opening device of rope-like structure is wound and connected with the notch 27 provided at the edge near the handle ring 28 (see Figure 7 ).

[0034] Antifreeze as crystalline magnesium chloride MgCl 2 ·6H 2 O is the main component, and its composition is 20% crystalline magnesium chloride and 80% w...

Embodiment 3

[0036] The difference with embodiment 1 is: the bottom of the lower half outer box 1 is provided with a boss (see Figure 4 , 8 ), leaving a space between the bottom of the liner 2. Antifreeze as crystalline magnesium chloride MgCl 2 ·6H 2 O is the main component, and its composition is 50% crystalline magnesium chloride and 50% water by weight percentage.

Abstract

An expendable food box with self-heating function is composed of an external box, an internal two-layer box with a bulkhead to divide its inner space into upper space for food and lower space, and the antifreezing bag and heating calcium oxide bag, which are put in said lower space of internal box.

Description

technical field [0001] The invention belongs to cooking utensils, in particular to a disposable lunch box with self-heating function. Background technique [0002] It is a headache to heat the lunch of office workers, students, car drivers, especially those who travel and work in the field. Most of the lunch boxes currently used are box structures that cannot be heated by themselves. The Chinese patent also discloses a disposable lunch box (application number is: 03255513.X), which includes an inner layer lunch box and a lid, and also includes a shell and a heating element; A cavity is provided between the bottoms of the shells, and the lid matches the top of the shell to cover the disposable heat-insulating lunch box; the heating element is placed in the cavity between the bottom of the shell and the bottom of the inner lunch box. Its shortcoming is: when edible heating, the bottom that is enclosed within the outer casing of inner layer lunch box can be heated because of h...
