Description

  TECHNICAL FIELD The present invention relates to an instant food containing a container that is softened and restored by heating the frozen instant food contained in the container together with the container and a cooking method thereof.

  Conventionally, Patent Document 1 discloses an instant food container used for softening and restoring food by heating the instant food contained in the container together with the container. This technology has a double structure in which an outer container made of synthetic resin and a metal inner container that can withstand direct fire and heating of an electromagnetic cooker are removable, and in the case of direct fire or an electromagnetic cooker, the inner container is an outer container. In the case of a microwave oven, the food in the inner container is transferred to the outer container and heated to eat.

By the way, in the above technique, for example, when a heated inner container is re-fitted to the outer container and the outer container is used as a carrying container or a bottom cover, the inner container and the outer container are in contact with each other. The heat of the vessel and the food was directly transferred to the outer container, and the food was easy to cool and was not satisfactory in heat retention. In addition, the outer container, which is easy to cool, is heated in reverse, and depending on the temperature, it may be hot and not portable.
JP 2000-85853 A

  The problem to be solved by the present invention is to solve these conventional problems, provide an instant food in a container that has excellent heat retention and can be carried by bare hands even when the inner container is hot, and a method for cooking the same. It is in.

The configuration of the present invention that solves this problem is as follows.
1) An inner container made of a thin metal that can withstand direct fire is detachably fitted into an outer container made of a synthetic resin with the top open, so that a space is formed between the containers, and the foodstuffs are contained in the inner container. 2) Instant food in a container sealed and sealed 2) Instant food in a container according to 1) above, wherein longitudinal reinforcing ribs are formed on the entire side wall of the inner container 3) The outer container is made of foamed synthetic resin The instant food in a container according to 1) or 2) described above 4) The instant food in a container according to any one of 1) to 3) above, wherein the food is softened and restored by heating 5) The above 1) to 4) The cooking method for instant foods in any one of the containers, wherein the inner container which has been unsealed is detached from the outer container and subjected to a direct fire, and the inner container and the food are heated by the direct fire. The inner container is re-fitted to the outer container and eaten. Vessel filled in the cooking method of instant food.

  According to the present invention, since the air layer in the space between the inner container and the outer container is heated by the heat of the inner container, the cooling of the inner container is delayed and the heat retaining properties of the inner container and the foodstuff are enhanced. Further, since the outer container is not in contact with the heated inner container on the surface, it is difficult for heat to be directly transmitted, and it is possible to carry it with bare hands even immediately after heating.

  As the inner container of the present invention, a thin metal such as aluminum or stainless steel is formed in a dish shape. In order to prevent deformation due to a load from above, a longitudinal reinforcing rib is formed on the side wall over the entire circumference. The The outer container is made of a synthetic resin such as polystyrene or polypropylene, and is foam-molded to a predetermined thickness in order to enhance heat insulation.

  The inner container and the outer container are in contact with only the flange portion formed on the outer edge, and the distance between the outer surface of the inner container and the inner surface of the outer container is practically in the range of 5 to 15 mm. When it is 15 mm or more, the package becomes larger than necessary, and the transportation cost is increased. Embodiments of the present invention will be specifically described below with reference to the drawings.

  1-3 are examples in which the present invention is applied to instant cup noodles. FIG. 1 is a cross-sectional view of an instant food in a container according to the embodiment, FIG. 2 is an exploded perspective view of the container according to the embodiment, and FIG. 3 is an explanatory view showing a cooking process of the instant food according to the embodiment. In the figure, 1 is an outer container, 1a is a flange, 1b is an inner bottom surface, 2 is an inner container, 2a is a flange, 2b is an outer bottom surface, 2c is a reinforcing rib, 3 is a lid, 4 is a film, 5 is a space, 6 is Food, F is a stove fire.

  The outer container 1 of the present embodiment is made of foamed polystyrene having a thickness of 2 mm with the inner bottom surface 1b formed into a gently curved shape, and the inner container 2 is made of thin aluminum with the outer bottom surface 2b formed flat. The side walls of the vessel 2 are folded to form vertical reinforcing ribs 2c over the entire circumference.

  The outer container 1 and the inner container 2 are fitted together to form a space 5 of about 10 mm between the containers, and the inner container 2 contains the food 6 made of noodles, soup and ingredients in a frozen state, and is made of PET (polyethylene terephthalate). ), And the whole is wrapped with a polyethylene film 4, and transported, displayed and stored in this frozen state.

  When cooking this instant cup noodle, after peeling off the outer film 4, the lid 3 is removed and the outer container 1 and the inner container 2 are separated as shown in FIG. 3 (a). As shown, the inner container 2 is heated on a stove. Thereafter, the food 6 is gradually thawed and softened and restored, and the inner container 2 is fitted into the outer container 1 as shown in FIG.

  At this time, since the air layer in the space 5 between the inner container 2 and the outer container 1 is heated by the heat of the inner container 2, the cooling of the inner container 2 is delayed to increase the heat retaining properties of the inner container 2 and the food material 6. I was able to eat without chilling early. Further, since the outer container 1 is not in contact with the heated inner container 2 on the surface, it is difficult for heat to be directly transmitted, and it is possible to carry it with bare hands even immediately after heating.

  In addition, since the inner container 2 is re-fitted to the outer container 1 after heating, the outer container 1 can be used as a jar and no bottoming is required, and charring etc. is concealed by the outer container 1 and is inconspicuous and has a good appearance. The space 5 is excellent in cold insulation even in summer, and the time restriction during transportation is reduced. Further, the outer container 1 can prevent deformation and breakage of the inner container 2 to reduce defective products, and the outer surface of the outer container 1 can be easily printed with characters, pictures, and the like as compared with a metal container.

  The present invention is mainly used for frozen instant foods, but can also be used for cold instant foods and ordinary foods.

It is sectional drawing of the instant foodstuff containing a container of an Example. It is a disassembled perspective view of the container of an Example. It is explanatory drawing which shows the cooking process of the instant foodstuff of an Example.
