[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to an instant preservation food with a heating element.

[0002]

[Prior art]

 Retort foods are ready-to-eat foods prepared by packing cooked foods in resin film bags, sealing them, and heat-sterilizing them in a pressure cooker. When eating, boil the water and put the retort food in boiling water, or put the retort food in a microwave oven and heat the retort food. After that, the retort food eats the warmed cooked food out of the bag.

[0003]

[Problems to be solved by the invention]

 However, retort foods such as those described above require a fire for boiling water, a stove, or a microwave oven to eat them. Therefore, in the outdoors without a microwave oven or a stove, it takes time to set up a fire and boil water. Also, in mountainous areas and battlefields where fires cannot be caused, they cannot be heated and cannot be eaten.

[0004]

[Efforts to solve the problem]

 Recently, various types of heating elements have been developed that generate heat without emitting a flame due to a chemical reaction or an electrochemical reaction upon contact with water. If such a heating element is used, it is possible to heat the retort food in the presence of water. Put the heating element and the retort food in a container and pour water, soak the heating element and the retort food in water. Then, the heating element contacts the water and generates heat, and the water becomes hot water to heat the retort food.

[0005] Therefore, it has been conceived that a bag is used as a container for storing water, and the heating element and the retort food are sealed and packaged in the bag. In this way, the retort food, the heating element and the bag are not united and bulky, and the handling such as storage and carrying becomes convenient. In addition, since the heating element is sealed in a non-permeable bag and is shielded from external water and moisture in the atmosphere, it is possible to prevent unexpected heating during storage or transportation.

When heating the retort food, the bag is opened, water is poured into the bag, and the heat generator and the retort food in the bag are immersed in water. Then, the heating element generates heat, and the heat heats the retort food.

[0007] Furthermore, the present inventor has conceived of putting a retort food and a heating element in a box in which a package in which a heating element is sealed in an impermeable bag is packed. In this way, the retort food can be heated and then the warmed cooked food can be transferred to the packaging box, and the packaging box can be used as tableware.

[0008]

[Means for Solving the Problems]

 The first invention is an instant preservation food characterized by sealing a cooked food and sterilizing high-pressure heat-treated retort food together with a heating element that generates heat when exposed to water in a non-permeable bag. is there.

[0009] The second invention is that a plurality of retort foods, which have been sealed and cooked and heat-sterilized under high pressure, are sealed in a non-permeable bag between them with a heating element which generates heat when exposed to water. It is an instant preserved food.

[0010] The third invention is an instant preservation food characterized in that the instant preservation food of the first invention or the second invention is placed in a packaging box also serving as tableware.

[0011]

[Effect of the invention]

 In the present invention, retort food can be heated without a fire or stove, or a microwave oven, for boiling hot water. It is easy to heat retort food without a microwave oven or a stove.

[0012] The retort food, the heating element and the bag, or the retort food, the heating element and the bag and the tableware are integrated into a single piece, so that they are bulky and convenient to store and carry.

[0013] Further, since the heating element is sealed in a non-permeable bag and is shielded from external water and atmospheric moisture, there is no danger of sudden heat generation during storage or transportation.

[0014]

[Embodiment of the invention]

 [First Example (Refer to FIGS. 1 to 3)] As shown in FIG. 1, the instant preserved food of this example is a retort food 1 of a staple food (rice), a side meal (curry, stew, beef bowl ingredients, a Chinese bowl). ), A retort food 4, a heating tool 7, and an impermeable bag 10.

As shown in FIGS. 1 to 3, a retort food 1 as a staple food is prepared by packing a prepared staple food 2 in a rectangular bag 3 of a resin film, sealing it, and sterilizing it with a high pressure cooker. Is an instant preserved food. The retort food 4 as a side meal is a square plate-shaped instant preservation food prepared by packing a prepared side meal 5 in a rectangular bag 6 made of a resin film, sealing it, and heat-sterilizing it in a high-pressure cooker.

The heating tool 7 includes a square plate-shaped heating element 8 in a water-permeable square bag 9. The heat generating body 8 is made by mixing a super-corrosive alloy powder of magnesium MgFe having iron and a polymer powder of ultra-high molecular weight polyethylene, putting the mixture into a mold, forming a rectangular plate shape, and heating the polymer powder. It is a porous body obtained by melting and cooling. The heating element 8 is porous so that water or saline water penetrates, and when it comes in contact with water or saline solution, water and magnesium undergo an electrochemical reaction to generate heat without generating a flame. The bag 9 is a water-permeable paper or nonwoven bag similar to the bag of the tea pack.

As shown in FIG. 2, the impermeable bag 10 is formed by stacking two rectangular transparent resin films 11 and welding the left and right sides 12 and the lower side 13 to each other. As shown in FIG. 1, a rectangular plate-shaped retort food 1 and a side meal retort food 4 are inserted with a square plate-shaped heating tool 7 interposed therebetween, and the air inside the bag 10 is removed while the air inside the bag 10 is removed. The side 14 is welded to close the upper opening. The retort food 1 as a staple food, the retort food 4 as a side meal and the heating tool 7 are vacuum-packaged. Cutouts 15 are provided at the left and right ends of the upper portion of the bag 10.

When heating the instantly stored food of the present example, the upper side 14 of the bag 10 is cut out using the notch 15 on the upper side of the bag 10, the upper side of the bag 10 is opened, and the bag is opened from the opening. Water is poured into the bag 10, and the retort foods 1, 4 and the heating tool 7 in the bag 10 are immersed in water.

Then, the water in the bag 10 penetrates into the water-permeable bag 9 of the heating tool 7 and comes into contact with the heating element 8, the heating element 8 generates heat, and the water in the bag 10 becomes hot water. The retort foods 1, 4 immersed in the water in the bag 10 are heated. Since the heating element 8 is sandwiched between the two retort foods 1 and 4, the heat of the heating element 8 is easily transmitted to the retort foods 1 and 4. During heating, the upper portion of the bag 10 is folded to close the upper opening, preventing heat in the bag 10 from escaping from the upper opening.

After the retort foods 1 and 4 are heated, they are taken out of the bag 10, the bags 3 and 6 of each of the retort foods 1 and 4 are opened, and the cooked staple 2 and side meal 5 that have become warm are eaten.

[Second Example (See FIGS. 4 and 5)] In the instant stored food of the present example, the instant stored food of the previous example is packaged in a packaging box also serving as tableware.

The packaging box 21 also serving as a tableware is made of cardboard, and a waterproof layer such as a metal foil or a resin film is laminated on the inner surface of the cardboard. As shown in FIG. 4, a lid 23 is openably and closably mounted on a flat rectangular box body 22 having an open upper surface.

As shown in FIG. 5, the packaging box 21 has a shallow box main body 22 in which the instantly stored food is placed, and an open upper surface of the box main body 22 is closed with a lid 23.

When the instant stored food of the present example is heated and eaten, the lid 23 of the packaging box 21 is opened, and the instant stored food of the previous example is taken out from the box body 22 of the packaging box 21. As in the previous example, the retort foods 1, 4 are heated and removed from the bag 10, and the bags 3, 6 of each retort food 1, 4 are opened.

Then, the cooked staple 2 and side meal 5 that have become warm are transferred from the bags 3 and 6 to the box body 22. The packaging box 21 is used as tableware. There is no need to prepare separate dishes. The main food 2 and the side food 5 in the box body 22 are eaten with a spoon or chopsticks. Eating from the shallow box body 22 is easier than eating from the bags 3 and 6.
