Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a food packaging container which can be heated and cooked by a microwave oven while the food is packaged, and a food package packaged by the container.

[0002]

2. Description of the Related Art For example, as a set of pots and udon, raw noodles, ingredients, condiments, soup stock, etc. are sealed in bags made of synthetic resin film, and these bags are stored in aluminum foil molded containers for sale. At the time of cooking, it is only necessary to open these bags, put the contents into an aluminum foil container, and heat the container by putting it on a stove. However, this heating cooking requires almost the same time as that for cooking a normal pot or udon.

[0003]

In order to further reduce the time, a method using a microwave oven which has been widely used is considered.
In this case, an aluminum foil container cannot be used, so a heat-resistant synthetic resin container or porcelain will be used.However, it must be a set containing raw noodles, ingredients, condiments, soup stock, etc. in a packaging bag. Is the same as in the case of the aluminum foil container described above, and the labor for opening the packaging bags is also the same.

[0004] In order to save the labor of packaging dashi and the like at the time of production as described above and the labor of opening at the time of cooking, recently, raw noodles and jelly-like dashi soup, tools and the like are stored in heat-resistant synthetic resin containers as they are, A package that can be eaten simply by being put into a microwave and cooked has appeared.

In such a package, raw noodles and jellied broth (hereinafter referred to as “soup”) are initially heated as separate solids. In particular, the raw noodles are dried and solidified as soon as they are directly heated. There is a problem that so-called tanning may occur, and the taste is significantly impaired. Therefore, various ideas have been devised. For example, there is a method in which a jelly-like soup is arranged substantially at the center of raw noodles, and the jelly-like soup at the center, which is easily heated, is dissolved as soon as possible so that the raw noodles infiltrate into the liquid soup. However, this method also fails to sufficiently prevent the baking of raw noodles near the outer periphery.

Therefore, there is a method in which raw noodles are collected and solidified in advance in a jelly-like soup, and this is further placed on the jelly-like soup and stored in a container. However, this too
When the noodles are hardened with the jelly-like soup, the ends of the noodles protrude from the solidified mass, and the portions are baked in a microwave oven, which again causes the texture to deteriorate.

[0007] In any of the packaging forms, the jelly-like soup is first liquefied and gradually stored at the bottom of the container from the positional relationship between the melting temperature of the jelly-like soup and the noodles.
Since the noodles are gradually immersed and cooked in the liquid, there is a problem that the cooking time is long.

It is an object of the present invention to prevent the contents from being dried and solidified by heating cooking such as the above-mentioned baking and shorten the cooking time.

[0009]

In order to solve the above-mentioned problems, a microwave packaging container according to the present invention has a heat-resistant synthetic resin container main body having a bottom wall and a peripheral wall rising from the peripheral edge thereof, and a large number of through holes. It consists of a heat-resistant synthetic resin inner plate having a bottom wall and a peripheral wall rising from the periphery thereof. The inner plate is supported near the opening of the container body, and a storage space for contents is formed in the container body below the inner plate. The configuration was adopted.

It is preferable that a part of the opening is opened without covering the entire opening of the container body with the inner plate.

Further, the food package of the present invention employs a structure in which a jelly-like soup is stored in the middle plate and food is stored in the container body.

It is preferable that the jelly soup is crushed to an appropriate size.
