Hereinafter, an embodiment of a container for freezing food of the present invention (hereinafter, simply referred to as a container) and a method for producing frozen food using the container will be described. The embodiments shown below are merely examples of the present invention, and the technical scope of the present invention is not limited to the exemplified embodiments.

1 to 9 show an example of a container. 10 and 11 show an example of a frozen food product molded by a container.

As shown in FIG. 1, the container 1 of the present embodiment has a plurality of food storage holes 11 and a concave groove 12 for communicating the adjacent storage holes 11. The storage hole 11 and the concave groove 12 have a shape in which food is stored in the storage hole 11 and the liquid is collected when the liquid is poured into the container.

As shown in FIGS. 6 and 8, the storage hole 11 has a wall portion 111 that descends downward from the upper end portion 13 of the container 1, and a bottom portion 112 that exists at the lower end of the wall portion 111. The number of storage holes 11 may be two or more. The container 1 is provided with a total of nine storage holes 11, three in the vertical direction and three in the horizontal direction. The shape of the storage hole 11 is changed according to the shape of the food to be stored. In the container 1 of the present embodiment, the shumai is stored in the storage hole 11. The shape of the storage hole 11 is a substantially cylindrical shape that matches the outer shape of the shumai.

As shown in FIGS. 6 and 8, the bottom 112 of the storage hole 11 is provided with a convex portion composed of a circular ridge 113. The convex portion reduces the area where food comes into contact with the bottom 112 of the storage hole 11. As a result, the container 1 and the frozen food are easily separated from each other. The bottom 112 of the storage hole 11 is not provided with a through hole. When the liquid is poured into the storage hole 11 or the concave groove 12, the liquid collects in the storage hole 11 or the concave groove 12.

As shown in FIG. 1, the concave groove 12 has a shape that allows adjacent storage holes to communicate with each other. In the container 1, the concave groove 12 is composed of a concave portion recessed downward from the upper end portion 13 of the container. The cross-sectional shape of the concave groove 12 is an arc shape as shown in FIGS. 7 and 9. In the vertical direction of the container, a groove 121 having an arcuate cross section is arranged along the vertical direction. In the lateral direction of the container, two concave grooves 122 having an arcuate cross section are arranged in parallel along the lateral direction. As shown in FIGS. 7 and 9, the cross-sectional area of the concave groove 122 is smaller than the cross-sectional area of the concave groove 121.

The above-mentioned container 1 is used as follows. That is, the step of putting the food into the plurality of storage holes 11 of the container 1, the step of pouring the liquid into the concave groove 12 or the storage hole 11 of the container 1, and the food and the liquid put in the storage hole 11 and the concave groove 12. The step of freezing the whole container 1 is carried out. It should be noted that either step of adding the food and the process of injecting the liquid may be carried out first. The step of freezing the food and the liquid is carried out after carrying out the step of putting the food and the step of pouring the liquid. The temperature at which the food is frozen may be set to an appropriate temperature according to the characteristics of the food and the finish of the frozen food, for example, setting it to -30 ° C or lower.

When the food 81 stored in the container 1 and the liquid 83 are frozen by the above-mentioned method, the frozen food 8 shown in FIGS. 10 and 11 is obtained. The frozen food 8 has a shape in which a plurality of foods 81 are connected by a connecting portion 82 in which the liquid accumulated in the concave groove 12 is solidified. The shape of the connecting portion 82 is a shape to which the shape of the concave groove 12 of the container 1 is transferred. Similarly, the shape of the frozen food 81 is also a shape to which the shape of the storage hole 11 of the container 1 is transferred. The liquid 83 also adheres to the surface of the food 81 and is frozen, and the liquid on the surface of the food 81 and the connecting portion 82 are integrally frozen and connected.

As described above, the frozen food 8 produced as described above has a shape in which a plurality of foods 81 are connected by a connecting portion 82. In the frozen food 8, a plurality of foods 81 can be handled as a set. In the examples of FIGS. 10 and 11, a total of nine foods 81 can be handled as a set. The frozen food 8 produced as described above can be shipped, for example, by removing it from the container 1 and storing the frozen food 8 removed from the container in a bag made of synthetic resin.

When packing the frozen food 8 in the bag, if a plurality of frozen foods 8 are packed in one bag, the amount of the packaging material used is further reduced. When packing the frozen food 8 in the bag, for example, a method of laminating another frozen food 8 on one frozen food 8 or arranging another frozen food 8 next to one frozen food 8. Therefore, it is preferable to arrange the frozen foods 8 regularly. By arranging the frozen foods 8 regularly in this way, the frozen foods 8 can be shipped in a good-looking state even when the container 1 is removed. Further, by arranging the frozen foods 8 in a regular manner instead of randomly storing them in a bag, it is possible to prevent the frozen foods 8 from being damaged due to collisions between the frozen foods during transportation. As described above, in the container 1 and the manufacturing method using the container 1, the commercial value can be prevented from being impaired even though the packaging material is omitted.

In the above manufacturing method, the container 1 used for manufacturing the frozen food can be reused by removing the frozen food and then washing it. In the container 1, since the concave groove 12 is formed in an arc shape, the food residue is less likely to remain after the frozen food is removed. When shipping the frozen food 8, the container is not included in the product to be shipped, and the packaging material is only a bag containing a plurality of frozen foods and a case for protecting the bag. In this way, if the frozen food 8 is molded using the container 1, the container 1 is removed, the container 1 is stored in a bag, and the food is shipped, the problem of excessive packaging can be solved.

The liquid to be put into the container is not particularly limited, and is one selected from the group consisting of water; any seasoning such as salt, sugar, liquor, mirin, pepper, or herbs; cooking oil; and grain flour such as kataguri powder. A liquid containing the above raw materials can be used. The liquid includes, for example, a soup with a desired seasoning, a seasoning liquid such as a sauce, simple water, or a mixture of water, oil, and grain flour.

In the container 1 of the present embodiment, the length of the concave groove 12 extending between the adjacent storage holes 11 is such that when the adjacent foods are thawed and cooked, the adjacent foods do not come into contact with each other. It is set to be formed. If adjacent foods come into contact with each other when thawing or cooking frozen foods, the adjacent foods may bind to each other when the foods have been cooked, and the cooking finish may be impaired. be. By setting the length of the groove as described above, the finish of cooking is not impaired.

The frozen food 8 is handled with the container 1 removed. Therefore, the connecting portion 82 has a shape that does not break due to the weight of the frozen food 81 when the frozen food 81 is removed from the container 1 and lifted. The shape of the connecting portion 82 is a transfer of the shape of the concave groove 12 of the container 1. Assuming the cross-sectional area of the concave groove, if the cross-sectional area of the concave groove is excessively small, the cross-sectional area of the connecting portion 82 also becomes small, and the connecting portion 82 is likely to break due to the weight of the frozen food. The shape of the connecting portion 82 is set to a strength that does not easily break based on the weight of the frozen food, the number of storage holes 11 for storing the food, and the like.

In the above container 1, as shown in FIGS. 6 to 9, when the cross section of the concave groove 12 and the cross section of the storage hole 11 are assumed, the cross-sectional area of each concave groove 12 is the cross-sectional area of the storage hole 11. The shape is smaller than that. In this configuration, since the strength of the connecting portion 82 is appropriately lowered, the required amount of food can be easily separated by breaking the frozen food at the portion of the connecting portion 82. Examples of the method of breaking include a method of bending the connecting portion by hand and a method of striking the connecting portion 82 with the back of a kitchen knife. The concave groove may be provided with a convex portion for the purpose of forming a fragile portion in the connecting portion of the frozen food to be molded. The convex portion provided in the concave groove transfers the shape corresponding to the convex portion to the connecting portion of the frozen food to form a fragile portion. By providing the fragile portion in the connecting portion, when the connecting portion is broken, a trigger for breaking can be created and the connecting portion can be broken more easily. The shape of the convex portion is not particularly limited, but may be, for example, a wedge shape.

In addition, in FIG. 6 and FIG. 8, the cross-sectional area of the storage hole 11 is shown by filling with black. Further, in FIGS. 7 and 9, the cross-sectional areas of the concave grooves 121 and 122 are shown by filling with black.

Further, the cross sections in FIGS. 8 and 9 are cut in a direction intersecting the axial direction of the connecting portion 822 extending in the lateral direction. When there are a plurality of concave grooves as shown in FIG. 9, the sum of the cross-sectional areas of the plurality of concave grooves is compared with the cross-sectional area of the storage hole.

The lower limit of the cross-sectional area of the groove may be determined by the weight of the frozen food and the number of storage holes. The lower limit of the cross section of the groove varies depending on the conditions, but can be, for example, 1/10 or more or 1/5 or more of the cross-sectional area of the storage hole. Further, the upper limit of the cross-sectional area of the concave groove varies depending on the conditions, but can be, for example, 8/10 or less of the upper limit of the cross-sectional area of the storage hole.

As shown in FIG. 1, the flat surface side of the container 1 has an open shape in which the opening of the storage hole 11 is exposed without a cover such as a lid. Therefore, the shape of the frozen food is defined by the liquid level of the liquid poured into the storage hole 11 or the concave groove 12. By pouring the liquid into the storage hole 11 or the concave groove 12 until it reaches the upper end 13 of the container 1 and freezing it, as shown in FIG. 10, the shape of the frozen food on the flat side is flat. Can be provided with parts. Further, since the shape of the bottom surface side of the container 1 includes a flat portion , as shown in FIG. 11, the shape of the bottom surface side of the frozen food is formed so as to have a flat portion.

As described above, since the frozen food formed by the container 1 has a flat portion as shown in FIGS. 10 and 11, another frozen food is laminated on one frozen food. When this is done, the stacked frozen foods have a shape that is easy to stabilize.

As shown in FIG. 1, the outer peripheral edge 14 of the container 1 projects upward from the upper end of the storage hole 11, and the liquid poured into the storage hole 11 and the concave groove 12 is spilled. It is shaped to prevent it. The edge portion 14 is continuous along the outer circumference of the container 1. When the liquid is poured into the storage hole 11 or the concave groove 12 of the container 1, it is possible to prevent the liquid from spilling from the container 1.
