Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a bag used for easily prepared foods that can be eaten by simply immersing them in boiling water, especially for foods having a specific shape such as rice balls and nigiri sushi. Regarding.

BACKGROUND OF THE INVENTION Conventionally, simple cooking rice balls have been implemented in which freeze-dried rice is stored in a water-permeable bag of a predetermined shape.

These easily cooked rice balls are dipped in boiling water and then pressed into a shape using a predetermined mold or cloth, and then eaten after removing the bag.

Therefore, this simple cooking rice ball has the disadvantage that it is difficult to handle because the hot bag is compressed. The reason for compacting the rice grains is that the freeze-dried rice grains do not increase in volume much when returned, so they are not compressed by the bag, and if left as they are, they will fall apart and cannot be shaped into rice balls.

Therefore, in order to eliminate the need for compacting, a simple rice ball was devised in which rice was cooked, made into rice balls, and then freeze-dried (Japanese Patent Laid-Open Publication No. 115452/1983).
This easily cooked rice ball maintains its rice ball shape even after drying, and when returned, it becomes a rice ball as it is.

However, with this easy-to-cook rice ball, the rice is freeze-dried in the form of rice balls, which takes a lot of time to manufacture, and when it is rehydrated, water has to penetrate into the center of the rice balls, which takes a lot of time. It takes time.

The present invention has been devised for the purpose of improving these disadvantages and realizing a simple-to-cook food that does not require a compacting operation and does not require a lot of time during production or reconstitution.

Means for Solving the Problems The present invention consists of a porous heat-shrinkable film that is slightly larger than the desired shape, and stores therein a simple cooking food such as freeze-dried rice that is immersed in boiling water and reconstituted for consumption. This is a bag for easy-to-cook food that can shrink when returned to compact the food inside into a desired shape.

Function: This bag has heat-shrinkable properties, so it is tightened and compacted when the food is returned. Therefore, even if the loose freeze-dried rice is stored, it can be returned to the bag shape that has been set in advance.

EXAMPLE Hereinafter, an example in which the present invention is applied to the illustrated simply cooked rice ball will be specifically described.

In this easily prepared rice ball 1, 2 is freeze-dried rice, and the rice grains are individually separated. Although not shown, freeze-dried pickled plums, shijake, etc. may be added to the rice 2. A bag 3 is made of a heat-shrinkable film with small holes 4 formed over its entire surface by laser punching or the like. This small hole 4 is provided to provide water permeability to the bag 3, and may have a size that allows water to pass through but not rice grains. The material of the heat-shrinkable film and the amount of shrinkage are arbitrary, and the space 5 inside the bag 3 can be increased or decreased to correspond to the amount of shrinkage to obtain the desired compaction strength. The shape of the bag 3 is made slightly larger than the desired shape so that it will have a desired shape, such as a substantially triangular shape or a bale shape, after shrinking.

Therefore, when eating this easily prepared rice ball 1, dip the bag 3 in boiling water, put the rice 2 back in, shrink the bag 3 to compact the rice, and then take it out of the boiling water and remove the bag 3. Just that is enough.

Effects of the Invention As is clear from the above, in the bag for easily prepared food of the present invention, the food inside is compressed by heat shrinkage when immersed in hot water, so while storing loose food inside, the bag can be pressed by hand. It is possible to form a specific shape when reconstituted without hardening, and it is possible to realize extremely convenient and easily prepared foods such as rice balls. In addition, the food stored inside can be separated into pieces, making it possible to use rice with individual rice grains, which speeds up the penetration of moisture when returning the rice and prevents the traditional lumpy food. While it takes about 10 minutes, it can be restored in about 7 to 8 minutes. Furthermore, when using freeze-dried rice, it is possible to use cooked rice that is rolled out thinly into a plate shape and processed in a short period of time, making the production more efficient.

Therefore, by using the bag of the present invention, it is possible to realize a simple-prepared food that requires no effort to eat and is easy to manufacture.
