Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a portable cold storage box, particularly in a case where it is necessary to serve a large number of guests (mainly group guests) with meals such as sashimi at one time at meals at an inn or the like. If it is too late to prepare, it can be advantageously used to store seafood that has been cooked on sashimi and placed on a plate in advance. .

[0002]

[Prior art]

 In the above case, it is possible to store the sashimi on a plate in advance in the electric refrigerator. However, if it is stored in the freezer, it will need to be thawed, and if it is thawed one by one, it will not be possible to deal with the above situation, and storing it in the refrigerator will serve a large number of customers. This requires not only a fairly large electric refrigerator, but also the sashimi on the plate, which occupies the electric refrigerator and preserves the freshness of fresh products that require daily cold storage. It may cause trouble. Furthermore, an electric refrigerator consumes electricity, and the food to be cooled needs to be taken in and out by opening and closing the door, and if it takes a long time to take it out, the door will be left open and its use will be hindered. It can be a matter.

On the other hand, it may be possible to use a gas refrigerator for cold storage, but a gas refrigerator is not common and has the same problem as when using the electric refrigerator.

On the other hand, in fishing, a fishing cooler is used to preserve the freshness of the fish and also serves as a container, and this can also be used for the above-mentioned purposes. However, in general, the fishing cooler is arranged such that ice as a cooling medium (refrigerant), dry ice, an ice pack, or the like is randomly arranged in the cooler, and normally, it is efficiently cooled and stored. To do so, the fish is directly brought into contact with ice as a cooling medium (refrigerant), dry ice, an ice pack, or the like. In addition, the bottom surface is configured as a flat surface, and when considering the use as described above, remove the refrigerant one by one to take out the sashimi on the plate surrounded by the refrigerant. The sashimi on the plate had to be taken out, and because the sashimi got wet with the refrigerant such as ice, not only the freshness of the sashimi declined, but in general, the sashimi plate had the stepped upper part raised diagonally. The sashimi plate is configured so that an ice pack or the like dive under the sashimi plate, which causes the sashimi plate to tilt. In short, the fishing cooler does not take into consideration the case where it is necessary to serve a large number of customers (mainly group guests) at the same time at meals, such as sashimi, at meals, etc. Therefore, the point is that the condition is that it serves as a container that preserves the freshness of the caught fish and also serves as a container.

[0005]

[Problems to be solved by the device]

 The present invention is intended to eliminate the drawbacks of the above-mentioned conventional techniques. The above and other objects and novel features of the present invention will be apparent from the description of the present specification and the accompanying drawings.

[0006]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention provides a box body, which is formed by a heat insulating member, having a cross-shaped groove formed in a substantially central portion of a bottom surface of a box body, the cross-shaped groove being used for partitioning the box. The present invention relates to a portable, simple cool box characterized in that an object to be cooled, which needs to be cooled and stored, can be placed on each partition on the bottom surface of the main body.

[0007]

[Action]

 According to the above means, since the groove is provided on the bottom surface of the box body, and the groove is provided in the shape of a cross in the substantially vertical and horizontal center of the bottom surface of the box body, the cooling medium is stored in the groove. As a result, cool air diffuses from the center of the box body to the entire surroundings, and the cooled object can be kept cool efficiently. By installing the cross-shaped groove, a plurality of partition parts are provided between the groove part and the wall of the box body, and each cooled part individually needs to be cooled and preserved such as food to be cooled. A place where it can be placed can be secured. In particular, when the cooling medium is stored in the groove, the groove is formed so that part of the cooling medium is exposed upward from the bottom surface of the box body, thereby enhancing the effect of keeping the inside of the box body cool. In addition, when a sashimi dish with a stepped rising configuration is placed on the sashimi plate, the cooling medium prevents the sashimi plate from moving to the left and right, and acts as a stopper. Can be fulfilled. Therefore, if a large number of group guests come to the hotel such as an inn with a number of buses and need to serve food such as sashimi at the same time during meals, use a cooling medium in the groove on the bottom of the box body. Keep the freshness of the sashimi by storing it and placing the seafood that has been prepared on the sashimi and placed on a plate in each of the partitions on the bottom of the box body. Since it has been cooked and the serving has already been completed, you can quickly prepare meals by simply taking out the prepared dishes from the box body and placing them side by side on a table, etc. You don't have to. This reduces labor and saves labor cost significantly. Unlike using an electric refrigerator, it does not consume electricity, it eliminates the concern of leaving the door open when taking it out, and it is quite large to store the sashimi prepared in a plate in advance. No electric refrigerator is required, and the sashimi on the plate occupies the electric refrigerator, which does not hinder the freshness preservation of fresh products that require daily cold storage. In the above case, the sashimi on the plate can be placed in the four partitions, so store the sashimi on the plate in each cold box and stack these cold boxes in multiple stages. This makes it easier to deal with the large number of group guests as mentioned above.

When a fishing cooler (general stomach, shoulder bag type) is used as a container for storing freshness of fish, the bottom surface of the fishing cooler is a flat surface. Not only sashimi placed on a plate, but also ice as a cooling medium (refrigerant), dry ice, ice packs, etc. will be placed on each surface, and the cooling medium will be removed and placed on that plate. The sashimi must be taken out, the sashimi gets wet with a cooling medium such as ice, and not only the freshness of the sashimi decreases, but generally the sashimi plate has a stepped rising form, and there is an ice pack etc. under the sashimi plate. If you dive into the sashimi dish, the sashimi dish will be tilted and the sashimi dish will spill out of the dish. A groove that can store the cooling medium is provided in a cross shape in the center of the cross, and the bottom of the box body is divided into partitions by the cross groove, and the sashimi placed on the plate is placed on each partition. Since it is possible to remove the refrigerant one by one, it is not necessary to take out the sashimi placed on the plate, and the cooling medium is dropped in the groove and the movement of the sashimi plate is stopped by the cooling medium, so you can carry it etc. Even when doing so, the movement of the sashimi plate can be prevented, and the groove for storing the cooling medium and the partition for placing the freshly prepared sashimi that needs to be kept fresh are separate, resulting in stepped sashimi. It is possible to prevent ice packs, etc., from diving under the dish, causing the sashimi dish to tilt and spilling the sashimi dish out of the dish.

The cold storage box according to the present invention is made of a heat insulating material. For example, if the cold storage box is made of lightweight styrofoam resin as a heat insulating material, it can be carried, for example, from a kitchen to a dining room. Since the inside of the box body has been devised as described above, the freshness of fish etc. can be easily achieved without the need for a large-scale cooling device such as an electric refrigerator or a gas refrigerator. Since it can be used both as a storage and a container, it has the advantage that it can be conveniently used even when it is simple and small, and even when serving sashimi on a plate.
