Description

[Detailed Description of the Invention] This invention relates to a food container, and more specifically, to a food container in which food stored in the container can be carried in a heated state.

When selling foods, containers with lids made of synthetic resin are used to facilitate packaging and transportation.

These containers are made of polystyrene resin, etc., and are molded into a container and a lid, either integrally or separately.In either case, food is placed inside the container and then the lid is placed on the container before being sold. It is said to carry this with you, but it is okay if the food in the container can be kept cold when eaten, such as sandwiches or salads, but if it is not necessary to keep it cold when eaten, such as hot dogs or hamburgers. However, there are some things that go downhill and become unpalatable.

For this reason, there are containers made of foamed resin to prevent the food inside the container from getting cold, but it is impossible to maintain the heat retention effect for a long time.

This invention aims to eliminate the above-mentioned drawbacks, and its features include a container with a plurality of ventilation holes in the bottom, a lid for this container, and a container that is stored inside the container. It is characterized by comprising an intermediate container into which food is directly placed, and an oxidation heating element housed between the container and the intermediate container, and the heating element heats the food placed in the intermediate container. The present invention provides a food container with

This invention will be described in detail below with reference to an embodiment shown in the drawings.

As shown in Figure 1 and Figures 2a and 2b, the food container of this invention consists of a container 1 and a lid 2 that are integrally formed by casting a non-toxic heat insulating resin such as expanded polystyrene resin through a hinge part 3. It is molded.

The container 1 is provided with a plurality of ventilation holes 12 in the bottom 11, and an inner container receiver 13 is provided for receiving the inner container 4 by protruding inward around the part where the ventilation holes are opened, and further A curled edge 14 that curves outward is formed at the edge of the opening.

As shown in FIG.
A gathered edge 21 is formed in contact with the inner surface on the opening side of 5 and the curled edge 14 at two places.

The inner container 4 is made of polypropylene resin or aluminum foil, and a side wall 41 is lower in height than the container 1 by the height of the inner container holder 13, and a curled edge 42 that contacts the curled edge 14 is formed on the opening edge side of the side wall. has been done.

Between the container 1 having such a shape and the medium container 4, a non-flame oxidation heating element 5 in which, for example, iron powder, carbon powder, cellulose, chloride, and water are each sealed in a bag in a fixed proportion is placed. Contain or prepare separately.

The food container of this invention is constructed as described above, and in use, the oxidation heating element 5 is taken out from the outer bag, kneaded with the breathable inner bag body, and then the inner bag containing the heating element is loosened. After the body is stored between the inner container and the bottom of the container, air is passed through the above-mentioned heating element 5 through the ventilation hole 12 to promote a chemical reaction, and the heated food is then placed in the inner container 4. 22 is inserted into the outlet piece 16 of the container 1 and locked, it is heated by the chemical reaction heat (approximately 60 to 80°C) of the heating element 5, and during the period during which this chemical reaction continues, the most active reaction occurs. Foods placed in the container can be kept heated for several hours to m hours.

Note that the hinge portion 3 is provided with a steam exhaust port 31 for discharging the steam generated from the food products by heating to the outside, so as to prevent steam from being trapped inside.

In addition, in order to further increase the heating and heat retention effect, the lid 2 side is connected to the container 1.
It may be constructed in the same manner as above, and a heating element may be housed between the inner container and the lid to heat the food from both the top and bottom sides.Furthermore, if both the container and the lid are made of foamed plastic, it can be used as a somewhat container. Although it has a high volume, it has a good insulation effect and can prevent heat radiation from the surrounding area.

As described above, this invention consists of a flat container 1 having a plurality of ventilation holes 12 in the bottom 11, and a lid 2 in which the container 1 and the lid 2 are molded into one body via a hinge part 3. The height of the side wall 41 is lower than the container 1 by the height of the tongue piece 22, the insertion piece 16, and the middle container receiver 13 integrally formed on the container, and the height of the inner container receiver 13, and the opening of the side wall 41 A curled edge 42 that contacts the curled edge 14 of the container 1 is formed on the edge side,
It is composed of an inner container '4 which is housed in the container 1 and directly contains food, and an oxidation heating element 5 which is housed between the container 1 and the inner container 4. Since the structure is such that the food is heated in the container, the air is brought into convective contact from the many vent holes at the bottom to almost the entire lower part of the oxidation heating element 5, so the heat generation efficiency is good, and the heat generation efficiency is good. Not only can the movement of the heating element be prevented by the receiver, but also the upper M2 can be folded from the hinge part 3 and the locking tongue piece 22 and the insertion piece 16 can be carried compactly in a bag shape, making it convenient to carry. However, since both the container and the lid are flat, they can be stacked and carried.
