Description

[Detailed description of the invention] (Field of industrial application) This invention is a food container that is self-heated by a heating agent, especially in the shape of a bento box, and can be used to store rice, tempura, grilled eel, etc. This relates to a food container suitable for self-heating food placed on top or side foods that are desired to be heated.

(Prior Art and its Problems) A medium container for storing food inside a container having a lid, which is a food container that can be easily carried and can optionally heat the contents, especially for solid food. An oxidation heating element is housed between the bottom of the inner container and the bottom of the container, and a number of ventilation holes are provided in the bottom of the container housing the oxidation heating element. A device is known in which the above-mentioned heating element is made to generate heat by oxygen in the atmosphere flowing in through the pores to heat food (Utility Model No. 57).
-156470).

The oxidation heating element used in this food container is placed in a breathable bag, and when the food container is massaged, a chemical reaction occurs with oxygen and generates heat. Therefore, during the heat generation time, it is necessary to let outside air flow in from outside the container through the ventilation hole, and the efficiency of heating the inner container is not good.

(Means for Solving the Problems) An object of the present invention is to provide a self-heating type food container that can efficiently heat a container containing food containing solids.

Hereinafter, the present invention will be explained in detail along with the explanation of the accompanying drawings.

FIG. 1 is a schematic perspective view showing an example of the container of the present invention with a partially broken surface, and FIG. 2 is a schematic vertical cross-sectional front view taken along the - line in FIG. 1.

In the figure, 1 is a container for storing food to be heated, and is made of aluminum foil. 2 is a lid of the container 1, and 3 is a partition wall for forming a heating chamber 4.
The partition wall 3 surrounds the container 1 from the outside with gaps 5 and 6 interposed between the side and bottom surfaces of the container 1, respectively, to form a heating chamber 4. Powder or granules of quicklime, which generates heat when in contact with the lime, are added.

This quicklime 10 is placed in a bag made of water-permeable nonwoven fabric or the like. If necessary, the bag may be further placed in a moisture-proof plastic film or aluminum foil bag.

A loading section 7 for the water container 11 is provided on the side of the container 1 so as to be continuous with the partition wall 3. The water container 11 is a bag formed into a columnar or prismatic shape from a plastic film such as vinyl chloride resin or polyethylene, or a box formed from a foamed polystyrene sheet, which is filled with water and used in a sealed form. It will be done. If the box is made from expanded polystyrene sheet, it is also sealed with a lid made of expanded polystyrene sheet. As shown in FIG. 1, the water container loading section 7 is preferably shaped so as to surround the side surface of the water container 11 so that the water container 11 does not move. The bottom surface of this loading section 7 and the heating chamber 4
A water channel 9 is formed between the bottom surface and the bottom surface. As shown in FIG. 2, when the bottom of the water container loading section 7 is positioned higher than the bottom of the heating chamber 4, water will
The heat flows into the heating chamber 4 from above.

Reference numeral 12 is a piercing rod in the shape of a thin rod with a pointed tip, and is used to make a hole in the water container 11.

Steps 13 and 14 are formed in the upper part of the container 1, and steps 15 and 16 are formed in the partition wall 3 constituting the heating chamber 4 at positions corresponding to the steps 13 and 14, respectively. The container 1 is detachably attached to the partition wall 3 of the heating chamber 4 as shown in FIG.

Reference numeral 8 denotes a storage container that stores the entire bulkhead 3 of the heating chamber 4 with the container 1 mounted thereon and the loading section 7 on which the water container 11 is placed. In addition to the function of storing the heating chamber 4 and the like, this storage container 8 has the function of heat insulation and heat retention during the time when the food stored in the container 1 is heated by bringing water into contact with the quicklime 10 to generate heat. It is also something to be carried out. For this purpose, it is preferable to provide a gap 17 between the heating chamber 4 and the partition wall 3 . Then, as shown in FIG.
It is preferable that the open upper edge of the partition wall 3 rests on and engages with the open upper edge of the partition wall 3.

In the container of the present invention, the container 1 for storing food is made of aluminum foil to increase heating efficiency. Further, appropriate holes may be made in the bottom or side surface of the container 1 so that the steam generated in the heating chamber 4 can be used to directly heat the food.

The partition wall 3 is preferably made of a material with good heat resistance, such as a film or sheet of polypropylene, polyester, etc., or aluminum foil. The storage container 8 and lid 2 may be made of ordinary plastic sheets, but preferably made of polystyrene foam sheets.

Next, how to use the illustrated container of the present invention will be explained.

The food to be placed in the container 1 may be cooked food as is, or if it contains liquid, it may be sealed in a plastic bag.
If it is in a bag, transfer its contents to Container 1 when necessary. If the exothermic agent quicklime 10 is placed in a plastic bag, tear the bag and place it in the heating chamber 4.
onto the bottom of the If the quicklime is placed in a water-permeable bag such as non-woven fabric, it can be left in the bag.

In use, open the lid 2, insert the drilling rod 12 placed on the water container 11 diagonally from above the water container 11 toward the water channel 9, and make a hole in the water container 11. When the container 1 is opened, water flows out from the container 1, flows through the water channel 9 toward the bottom of the heating chamber 4, comes into contact with the quicklime 10, generates heat, and heats the food in the container 1.

In the above explanation, the case where the punching rod 12 is housed inside the lid 2 has been described, but the punching rod 12 is stored inside the lid 2.
It may be attached to the outside of the
In this case, the water container 11 can be perforated together with the lid 2 from the outside of the lid 2 without opening the lid 2.

(Effects of the invention) According to the food container of the invention, heating efficiency is extremely excellent.

The container of this invention generates heat by bringing water into contact with quicklime, and calculates the amount of quicklime and water required from the amount of calories needed to heat the object to a sufficient temperature. The volumes of the gaps 5 and 6 between the heating chamber 4 and the container 1 are adjusted based on the amount. In this state, the water injected into the heating chamber 4 generates heat in the quicklime 10, and the bottom and side surfaces of the container 1 are heated by the generated hot air and generated steam. The hot air and water vapor mentioned above are
It enters the container 1 through the path shown by arrow A in the figure and directly heats the contents. When vent holes are provided on the bottom and side surfaces of the container 1, the hot air and steam enter the container 1 through the vent holes and heat the container. Effective heating is thus achieved in the container of the invention.
