2. self-heating food is generally used when people play in the field or travel for a long distance, but the self-heating box in the prior art has large volume, large occupied space and inconvenient carrying;
3. the self-heating box is too big in order to prevent the internal pressure of box among the heating process, consequently can not make into sealed lid, consequently can appear exposing the condition of oxidation in the air from the heating package easily.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a self-heating bag to solve at least one of the problem that exists among the foretell prior art.
The utility model adopts the following technical scheme:
a self-heating bag comprises a vertical bag body, wherein the bag body comprises two side bodies, an interlayer is bonded on the inner side wall of each side body, the side body and the bottom edge of the interlayer are bonded on the same side, the two side bodies and the side edge of the same side of the two interlayers are bonded, water through openings are formed in the lower portions of the two interlayers, and the two water through openings are communicated; a self-heating bag which can generate heat when meeting water is arranged in a space formed between the interlayer and the side body.
Furthermore, the upper part of the side body is provided with a one-way air outlet valve.
Furthermore, the top of the bag body is provided with a double-layer zipper for opening and closing the bag body.
Furthermore, the two layers of interlayer are integrated and are respectively bonded with the side edges and the bottom edges of the two side bodies after being folded.
Furthermore, a heat sealing film is bonded on the inner side of the side body, and heat sealing films are bonded on both sides of the interlayer.
The utility model has the advantages as follows:
1. the inner side wall of the side body of the utility model is bonded with the interlayer, the side body on the same side is bonded with the bottom edge of the interlayer, the side edges of the two side bodies and the two layers of interlayers on the same side are bonded, the lower parts of the two interlayers are both provided with the water through ports, and the two water through ports are communicated; a self-heating bag which can generate heat when meeting water is arranged in a space formed between the interlayer and the side body. When heating, the object to be heated is placed between the two interlayers and is vertically placed, then water is added, the water amount on the two sides can be kept balanced through the water through port, the self-heating bag is expanded by the gas generated by the reaction of the water and the self-heating bag, the object to be heated can be clamped, and the heat conduction efficiency during heating is improved. When the pressure in the self-heating bag exceeds the critical pressure, the one-way gas outlet valve discharges the redundant gas, so that the pressure in the self-heating bag is kept below the critical pressure. The utility model discloses can avoid treating the heating object and through the water or the steam direct contact of self-heating package heating, safer, clean and health, and adopt the form of upright bag, change some among the prior art from the problem that the heating bag needs the positive and negative turn-over in the heating process, simplify operating procedure, eliminate because of the misoperation causes the possibility of scalding.
2. The utility model discloses a bag packed structure, occupation space is little, transportation and convenient to carry, and side body upper portion is equipped with the check valve, and the top is equipped with double-deck zip fastener, and when the check valve was with unnecessary gas outgoing, it is internal to prevent the air admission bag, prevents to store and in the transportation from heating package and air contact oxidation, and double-deck zip fastener can slow down the speed that the heat scatters and disappears.
