Description

DETAILED DESCRIPTION OF THE INVENTION A. Field of Industrial Application This invention relates to a cover or a cover plate for a food packaging container for storing a plurality of different types of foods, such as frozen foods, in one container.

mouth. Prior Art Conventionally, as shown in Fig. 1, a lower container body (1) having a partition wall (2) has a plurality of compartments (a], (b), (Cl, (di) separated by the wall). For example, pineapple potatoes (3), mixed vegetables (green peas, etc.).

Frozen boiled products such as diced carrots) (4)
.

Add fried chicken (5), grilled fish (6), etc., and seal the container body with a cover (7) of paper, plastic film, metal foil, or a composite thereof, as shown in Figure 2, and then seal the container as shown in Figure 2. It is well known that a plurality of foods are packaged in a single container such as a paper box.

When eating these foods, frozen foods need to be thawed, and it goes without saying that both regular foods and frozen F2 foods will taste better if they are heated to an appropriate temperature. Therefore, the food is stored in a container and placed in an oven or microwave to thaw, cook, and eat.

Ha. Problems to be Solved by the Invention In the above-mentioned conventional packaging, the cover is a film made of a uniform material, and it is difficult to cut it officially, so it is necessary to leave the cover on or to remove the entire cover. Place the container in the oven or microwave to thaw and heat.

However, with this method, the container (food) is heated from its surroundings by radiation and convection, so all foods are heated uniformly, and for example, it is possible to heat foods at high temperatures such as fried chicken, grilled fish, etc. to brown them. Foods that are more delicious when heated to a moderate temperature such as matshu brown potatoes, etc. Foods that are more delicious when heated to an appropriate temperature that does not cause burns. There is a drawback that the whole food cannot be eaten deliciously at its appropriate temperature because it is heated or the whole food is heated to a low temperature and the food that requires browning is not browned.

In addition, in the case of a microwave oven, microwaves are uniformly transmitted through the microwave, so the food is heated only in accordance with the physical and chemical properties of the food, making it impossible to achieve heating that is appropriate for taste.

This invention solves the above-mentioned drawbacks of conventional packaging, and allows each food to be heated to an appropriate temperature even if a container containing various foods is placed in an oven or microwave, making the whole food delicious. The purpose is to make it edible.

26 Disclosure of the Invention This invention is a container body which is divided into a plurality of compartments with a partition wall and stores different types of food in each compartment (including the case where one type of food is stored across two or more compartments). In a food container with a cover attached to it, the cover of the container is made of different materials for each section so that when the container is placed in an oven or microwave to thaw and heat, the supply of heating energy to the food in each section changes appropriately. Covers with varying thicknesses and opening ratios (including leaving certain compartments uncovered) can be used to thaw and heat all different types of food to temperatures appropriate for each food item, thereby eliminating the above-mentioned drawbacks. .

The present invention will be explained in more detail below by way of examples using the drawings.

E. Example Example 1゜As shown in Fig. 1, a container body (with a partition wall (2))
1) Various types of food are placed in the container, and as shown in FIG. 3, the food container is covered with a cover (7) of paper, plastic film 2, metal foil, or a composite film thereof. The cover (7) is provided with lines or perforations (8) to facilitate cutting along the food compartment line of the container. When eating this food, remove the cover along the lines or perforations (8) and place the entire container in an oven or microwave for cooking. Then, the portion of the food from which the cover (7) has been removed receives more energy from the oven or microwave than the other portions, and is heated more. Thus, for example, compartments such as fried chicken or grilled fish may be browned with the cover removed, while compartments such as vegetable salad may be left uncovered and eaten at a cold temperature. Furthermore, as shown in Figure 3, the food contents are divided into vegetable compartments on the surface of the cover.

If it is labeled as fried chicken, etc., it will be convenient for general consumers to remove the cover.

Embodiment 2 FIG. 4 shows another embodiment, in which a cutting instruction line indicating a partition line is provided on the surface of the cover (7). In this case as well, as in Example 1, if the cover is removed and heated according to the cutting instruction line, the supplied energy can be changed for each food item, so that the food can be eaten at an appropriate temperature.

Furthermore, it is convenient for general consumers to avoid mistakes when cooking by displaying instructions on the surface of the cover to indicate whether or not to remove the cover for each section as shown in the figure.

Example 3゜ FIG. 5 shows yet another embodiment.

In this case, part of the compartment of the container (for example, compartment (a) in Figure 1)
)) Edge (14) of part 03) of cover (7)
Apply adhesive to the cover and attach it to the rest of the cover with the adhesive. A part of the edge has a grip part (
15). Before putting the container in the oven and heating it, if you pull the grip part (151), the adhesive part (14) will peel off and the cover part 03 of compartment (a) can be easily peeled off, similar to Examples 1 and 2. It is possible to have the effect of

Embodiment 4 FIG. 6 shows still another embodiment, in which the material of the cover is changed for each section. That is, the cover (19) of the compartment of the container (compartments (al and (b) in Figure 1)
The other sections (sections (C) and (d) in Figure 1)
) The cover 06) is made of aluminum foil. For example, if you put this container in a microwave oven and heat it, the food in the section of the paper cover (19) will be sufficiently heated, but the food in the section of the aluminum foil cover (06) will be heated because the aluminum foil will prevent microwaves from entering. There is almost no heating, so each food item can be heated to an appropriate temperature.

Embodiment 5 - Fig. 7 shows yet another embodiment, in which the cover (19) of section (b) in Fig. 1 is made of paper, and the cover (18) of section (al) is made of thick aluminum foil. , ward i ((
The cover (17) of 1) is made of thin aluminum foil, and the section (C) is left without a cover. Section (C) (since there is no cover, add a plastic film over the cover as shown in the cross-sectional view in Figure 8).

Exterior packaging with paper, etc. In this case, the exterior (22
) is removed and the container is placed in an oven or microwave for heating. Different heating conditions can be obtained for each compartment, allowing the food to be heated to its appropriate temperature before being eaten.

Embodiment 6 FIG. 9 shows yet another embodiment. In this case, the container is covered with an aluminum foil cover, as shown in the drawing. In this cover, sections (C) and (d) are made of aluminum foil as they are;
There are many glue holes in the part of the cover.
The cover portion CD of bl has pores with a smaller porosity than the cover portion (20). In addition, in order to prevent the food from coming into contact with the outside air through the openings, the food is packaged with an exterior (22) as shown in the sectional view of FIG. 9 and FIG. 10. In this case as well, remove the outer cover (22) (in the case of a microwave oven, it is not necessary to remove it if the outer cover is made of a material that allows microwaves to easily pass through, such as plastic film or paper) and place the container in the oven or in the microwave. When heated in the microwave, different heating conditions can be obtained for each compartment, allowing food to be heated to its appropriate temperature before being eaten. In this case, a composite of aluminum foil and plastic film may be used instead of aluminum foil.

Of course, instead of aluminum foil, a plastic film or paper cover with a similar structure may be used for the oven.

Example 7 Food is stored in a compartmented container body (1) having a partition wall, and this is lined (24) with paper, plastic film, etc., like normal packaging. Separately, a cover plate (23) having a structure similar to that of Examples 4, 5.6 as shown in FIG. Cover with (1) and place in the oven or microwave. In this way, each food item can be heated to the appropriate temperature as in Example 6 and the like. According to this method, using a single cover
It is economical because a large number of containers (with the same food contents) packaged in the same manner as before can be effectively heated one after another to an appropriate temperature.

As explained in detail using a large number of embodiments beyond the effects of the invention, when the food container cover of the present invention is used, the container body is divided into a plurality of compartments by adding 4J partition walls, and each compartment has different types (2 or more). (including cases in which a type of food is stored in compartments)) are placed in an oven or microwave as a whole to thaw.

When cooking, each food can be eaten at the appropriate temperature by changing the supply of heating energy to each compartment. By simply changing the structure, the food containing different types of food in one container can be eaten deliciously as a whole, and the cost of packaging is also low. Furthermore, it is also possible to separate the cover of the container from the container, in which case the effect of the present invention can be applied to a large number of containers by sequentially covering the containers with one cover and heating the container in an oven or microwave. Since it can be heated while holding it, it is effective for household use and for foods such as boxed lunches.
