2. Description of the Related Art Cooked and processed foods such as cooked frozen noodles and cooked frozen foods containing cooked frozen cooked rice that can be easily cooked and eaten can enjoy delicious dishes in individual meal units, so the recent increase in consumption is remarkable. Is. A food package consisting of only one kind of food can be relatively easily produced if the material of the container or the packaging element is appropriate, but a food package consisting of two or more kinds of food is two or more kinds of food. There are a wide variety of conventional techniques in a wide range of fields, depending on the type of dishes prepared by mixing or the method of storage. Like the present invention, 2
Research and development in the field of technology of novel food packaging that allows easy mixing and cooking of one or more foods in a convenient manner is making rapid progress in the food industry. In order to obtain a food package that can be prepared by mixing two or more foods by a simple method at the time of eating with conventional technology, it is common to package one or more foods separately and package the whole as a whole. It was target. However, for example, to package the seasoning liquid in a bag made of synthetic resin, an expensive quantitative filling and packaging device is required, and a method for completely preventing the deterioration and spoilage of the seasoning liquid is also required. Therefore, small and medium-sized companies that do not have expensive quantitative filling and packaging equipment have to outsource the production of seasoning liquids and quantitative filling and packaging to external specialists, and the final manufacturer that manufactures food package does not really need it. In many cases, it is not possible to receive a variety of small amounts of seasoning liquid, and even if it is supplied, it becomes an expensive seasoning liquid and the flavor is uniform. It was not easy to modify important and basic cooking operations such as improving the content of the preparation and changing the amount of seasoning liquid. The patent applicant currently manufactures and sells cooked frozen noodles, but was particularly troubled by the problem of separately packaging seasonings such as seasoning liquid and frozen noodles and ingredients. Further, it is technically easy to separately package one or two or more types of foods by the conventional technique and package the whole as a whole, but the effect or benefit added specially could not be expected so much. Next, in order to facilitate understanding of the present invention, two patent references and utility model patents relating to cooked frozen noodles in the field of the related art will be described as reference documents. Patent application publication number Showa 60
No. 48145 "Instant chilled noodles" is a heat insulating container,
It is an instant chilled noodle consisting of ice at the bottom of the container and ice and a block of frozen noodles above the ice in the container.
With this technique, it is possible to thaw noodles in a short time and obtain cold noodles at a low temperature simply by pouring hot water. However, this technique is not a technique that can be easily applied to the entire package of foods in which two or more types of foods can be mixed and cooked at the time of eating. Also, "Package Frozen Noodles" of Utility Model Application Publication No. 35020 No. 35020 is packaged by placing frozen seasoning juice at the bottom of the heat-resistant container and then placing the noodles and ingredients in a frozen state. The packaged frozen noodles are characterized by being processed. With this technique, the noodles and ingredients are placed in a frozen state on the frozen seasoning juice located at the bottom of the container. Therefore, when heating from the bottom of the container during cooking, the seasoning juice first thaws and liquefies. ， The noodles and ingredients are dipped in this defrosted seasoning juice, and in this state, the noodles and ingredients are thawed and then boiled together with the seasoning juice.
The whole noodle can be uniformly dipped in the seasoning juice. However, this technique has not been a technique that can be easily applied to the entire package of foods in which two or more kinds of foods can be mixed and cooked at the time of eating.
