Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a food product cold storage container, and more particularly to a food product cold storage container that uses ice to cool food products such as fresh fish and meat.

[0002]

[Prior art]

 Conventionally, for example, as a fish box, which is a food product cold storage container for storing fresh fish, a box made of a foamed resin such as a Styrofoam resin with a flat bottom on which the fish is placed is used to cool the stored fish. When doing so, ice is placed on the fish that has been stored, or ice is spread on the bottom.

[0003]

[Problems to be solved by the device]

 However, when the ice for cooling is stored together with the fish as in the conventional fish box described above, there are the following problems. In other words, since the ice is in contact with the fish body a lot, the cooling effect is great, but the part of the fish body that comes into contact with ice is more likely to rot. A large amount of ice for cooling (cooling) is required, and dissolved water increases, so that the dissolved water causes bacteria to grow. There is a problem.

Therefore, the present inventor has dealt with the above-mentioned problems, and as a result of various researches and studies, as a result, in fresh fish, fresh vegetables, fruits, etc., only a part thereof is cooled, and It was clarified that it is possible to keep cold as if the whole container was covered with ice, and to keep cold with a small amount of ice.

The present invention has been made in response to the above problems, and the purpose thereof is to reduce the amount of ice for keeping cold and to maintain the freshness of foods such as fresh fish. It is to provide a cold storage container for food products that can be transported by.

[0006]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the food cold storage container of the present invention is a food cold storage container for keeping foods such as fresh fish using ice, and the food products are placed at the bottom of the box-shaped container body. A groove is formed so as to protrude downward from the surface on which the ice is kept, the ice for cooling is stored in the groove, and the ice is brought into contact with a part of the food.

Further, another food product cold storage container of the present invention is configured such that, in the above-mentioned device, leg portions are provided on both sides of the food food cold storage container body, and grooves are formed in the leg portions.

[0008]

[Action]

 The food product cold storage container of the present invention based on the above configuration can store the cooling ice in the groove protruding downward from the food product mounting surface, so, for example, when the fish body is stored and kept cold, It acts so that only a part of the fish body, for example, the head or tail, is in contact with the ice for cooling, or the fish body can be stored and kept cold without directly contacting the fish.

In addition, since the food product cold storage container of the present invention stores the cold storage ice in the groove portion so as to contact only a part of the food product such as fresh fish for keeping cold, The thawing water of (1) collects in the groove and does not come into contact with the food product, thereby acting to reduce the growth of bacteria.

【Example】

 Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings. 1 to 3 show an embodiment of a fishing box as a food storage container according to the present invention, FIG. 1 is a perspective view, FIG. 2 is a sectional view, FIG. 3 is a bottom view, and FIG. It is sectional drawing which shows the other Example of a device.

The fish box, which is a food cold storage container according to the present embodiment, is roughly provided with legs 3 and 3 on both sides 2 at the bottom of the box main body 1, and ice is stored in the legs 3 and 3. It has a structure provided with a groove portion 4 for carrying out.

The box body 1 is a rectangular box body made of styrofoam resin, and has a configuration in which a reinforcing rib 6 is provided on the bottom surface 5. The legs 3 and 3 are formed by bulging the bottom both sides 2 in the box body 1, and inside the legs 3 and 3, below the fish placing surface 7 on which the fish F is placed. Grooved grooves 4 and 4 are formed. Drain holes 8 are formed in the grooves 4 and 4 so as to communicate with the outside in order to discharge the water generated by freezing. The reinforcing rib 6 is formed in a cross shape.

Here, the groove portion 4 has a depth of about ¼ to ⅓ of the total height of the box body 1 and is usually set to 5 cm to 10 cm so that ice for cooling can be stored. It is configured.

In the fish box of this embodiment, the fish F is placed on the fish placing surface 7 as shown in FIG. 2 in a state where the ice 9 for keeping cold is stored in the grooves 4 and 4 of the box body 1. The ice 9 may only come into direct contact with part of the fish body F, here the head or tail, by placing it on the.

In this way, the portion of the ice cube 9 that comes into contact with the fish body F stored therein is reduced, so that the freshness of the fish body F can be maintained and spoilage can be suppressed, and at the bottom of the box body 1. Since the space is created, the contact area with the outside air is increased and the cooling effect is enhanced. In addition, the storage amount of the ice cubes 9 for cooling can be reduced while maintaining the cold insulation effect, so that the weight can be reduced, and when the fish body F is squid, according to the experiment, it works so as not to spit out the squid.

Next, in order to confirm the effect of the present invention, the fish box of this example and the fish box of the conventional example are used. In the case of this example, ice is stored only in the groove, By placing fresh fish on the fish mounting surface, and in the case of the conventional example, by placing ice for cooling on the bottom of the fish box and placing fresh fish on the ice for cooling, the lid is attached to each. The freshness-preserving state was compared by storing the sample in a refrigerating room in such a state and examining its appearance change over time and K value. As fresh fish, squid (mica) of the same quality obtained on the same day was used.

As a result, the following results were obtained. In other words, appearance after 12 hours: In the case of this embodiment: Change to a transparent color close to pink In the case of the conventional example: Many parts changed to red and partially changed to white Appearance In the case of this embodiment: a part that changes to red is generated, and part of it changes to white In the case of the conventional example: ...

By the way, the appearance of squid changes with time and is initially a transparent color, but as the freshness of the squid decreases, it changes from pink → white → red → white turbid. Therefore, in the above-mentioned example, it was confirmed that a difference of about 12 hours was observed in the change in freshness between this example and the conventional example. This is because in the case of the conventional example, the ice for cooling is in contact with the whole fish body, and the bacteria adhering to the box body and the bacteria in the waste are absorbed into the fish body together with the thawed water of the ice. It is thought that this is because self-digestion is promoted.

The amount of ice melted did not change in this example and the conventional example, and it was found that the amount of ice melted depends on the contact area with squid. Therefore, in the case of the present embodiment, the weight of the ice itself is reduced (about 1/2 to 1/3), and in the case of transportation, a large amount is transported by the same refrigerated vehicle as compared with the case of the conventional example. It was confirmed that it is possible.

Regarding the K value, after 24 hours, almost no difference was observed between the two and was 7 to 8%, but after 36 hours, in the case of the present example. While it was around 10%, the conventional example showed around 20%, and it was confirmed that the freshness quality was not in a good condition.

It should be noted that the present invention is not limited to the above-described embodiments, but includes configurations that can be modified and implemented within the scope of the present invention. By the way, in the above-mentioned embodiment, an example in which the present invention is applied to a fish box for keeping fresh fish cold is explained, but it is also applied to a food cold box for keeping fresh food such as meat and vegetables. The same can be applied. Further, although the groove portions are formed on both sides of the container body, the groove portions may be formed in the central portion and other portions.

Further, the configuration as shown in FIG. 4 may be adopted. In this configuration, the dam portion 10 is provided upright between the fish body mounting surface 7 and the groove portions 4 and 4 in the above-described embodiment. By providing the dam portion 10 as described above, the fish body F does not come into direct contact with the ice 9 for keeping cold, and the cold air by the ice 9 can exert a cold keeping effect. Further, as shown in FIG. 5, a bottom surface 11 may be provided, and a part for accumulating melted ice water may be formed on the bottom surface 11. This structure has an advantage that water containing waste products can be transported without being out of the container.

[0023]

[Effect of device]

 As is apparent from the above description, according to the food product cold storage container of the present invention, a groove portion projecting below the surface on which food products such as fresh fish are placed is formed at the bottom of the box-shaped container body. Since the ice for cooling is stored inside, the contact area between the stored food and the ice for cooling can be reduced, and the freshness of the food can be maintained to prevent spoilage.

Further, according to the food product cold storage container of the present invention, the ice for cooling is stored in the groove portion so that it comes into contact with only a part of the food product such as fresh fish for keeping cold. The thawed water of the ice for keeping cold is accumulated in the groove portion and does not come into contact with the food item, so that it has an effect of reducing the growth of bacteria.

Further, according to the food cold storage container of the present invention, since the space is formed at the bottom of the box-shaped container body, the contact area with the outside air is increased and the cooling effect can be enhanced. In addition, since the groove portion is used as the ice storage for cold storage, there is an effect that the storage amount of the ice for cold storage can be minimized.
