Abstract

The invention discloses a prepackaging self-heating food packaging box and a method. The packaging box comprises a box body and an inner box is embedded in the box body; a lower cavity is formed between the inner box and the bottom of the box body and an upper cavity is formed between the inner box and the top lid of the box body; the lower cavity contains a heating bag and a water bag; the innerbox contains food; a condiment packet is fixed on the inner side of the top lid; a switch is arranged on the box body or the top lid; and the switch can open the condiment packet and the water bag respectively or simultaneously. According to the arrangement, rotation of the switch is required in the process of heating; the upper drawstring is tight, and a condiment packet sealing element is firstpulled open and water is added to make the food moist; and the lower drawstring is loose, and a partition film and a water bag sealing member can be pulled open successively and water reacts with theheating bag to release heat. The operation is convenient and safe.

Description

technical field [0001] The invention belongs to the technical field of self-heating food, and relates to a prepackaged self-heating food packaging box and a method. Background technique [0002] With the advancement of social science and technology, people's lifestyles and life concepts have also undergone tremendous changes, and new fast food products continue to enter people's field of vision. In recent years, self-heating food has emerged in an endless stream, but it also has some problems. When the current self-heating products are in use, water is first added to the heating pack to generate heat in reaction, and then the food is added with water and placed on the upper part of the heating pack. This heating method has many steps, which is inconvenient, prone to accidents and unsafe. The chemical reaction between the heating pack and water will produce flammable gases, which will be dangerous if exposed to high temperature environments; when adding water manually, the ...
