JPH03162267A - Container for cold storage preservation - Google Patents

Abstract

PURPOSE:To make ice and cold storage agents unnecessary by making a roof tile function as a cold isulator by a method wherein a container is constituted of a roof tile on which fish or shellfish are placed and an expanded plastic box in which this roof tile is stored. CONSTITUTION:The title container is constituted of an expanded polystyrene box 2 and a roof tile 3 which is placed in the box. There are no limits for the expanded polystyrene box 2 as long as it is light and has a great heat insulating effect. This roof tile 3 is placed in this box, and functions as a plate to place fish or shellfish and a coldness accumulating material, and normally, a notched plain roof tile or plain roof tile is used. By this method, the roof tile 3 functions as a cold insulator, and ice and cold storage agent becomes unnecessary.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a container for refrigerated storage for the purpose of transporting seafood, particularly sashimi or sashimi fillets. [Prior Art] Conventionally, when transporting seafood, in order to maintain its freshness during transportation, the seafood was frozen or ice was added to the seafood. Recently, refrigerated trucks have also been installed in home delivery services, allowing fresh seafood to be delivered directly to households. For this reason, it has become possible to transport not only seafood itself but also sashimi prepared from seafood ● [Problem to be solved by the invention] However, sashimi tends to lose its freshness, and when transported to long distances, etc. This required large amounts of cold storage agent and water.

This problem can be solved if a refrigerated truck is used. However, even in that case, the freshness starts to deteriorate as soon as it is taken out of the refrigerated car, etc., so even in such a case, if a certain amount of cold storage agent or ice is not used, the sashimi etc. will easily spoil. . However, when transporting sashimi and sashimi fillets in this way, these are often 7i & final products that are delivered directly to consumers, so the sashimi and sashimi fillets, which are often expensive, are stored in cold storage. It is not a good idea from an aesthetic point of view to put it in a box in such a way that it will mix with the ice.

[Means for Solving the Problems] In view of the above points, the inventors of the present invention have finally developed the present invention as a result of intensive research. What makes it unique is the container used to store seafood in the refrigerator.
It consists of a tile on which the seafood is placed and a box made of foamed plastic to house the tile.

In this case, "cases in which seafood is stored in a refrigerator" refers to cases in which sashimi, fillets, peeled seafood, or uncooked seafood is transported in a refrigerated or frozen vehicle for home delivery, or when it is delivered at retail. This refers to cases where food is kept in the store's refrigerator or freezer at all times to maintain its freshness by keeping it at a low temperature when you buy it and take it home. Therefore, the term "refrigerated" here also includes the concept of freezing.

A ``tile'' functions as a plate for cultivating seafood and a cold storage material, and ``tiles'' or flat tiles are usually used. The size of the tiles themselves can vary depending on the overall size of the container, but regular tiles are often a little too large, so it is thought that tiles for walls have a suitable size. Ru. In addition, tiles are often coated with glaze, which is desirable in the present invention, but it is also possible to add glaze to the back side of the tile (often only the front side of tiles) for aesthetic effects. big. As for the color of the glaze, you can freely choose one that suits the seafood to be placed on it. Note that if you freeze the seafood in advance, dew may form on the surface of the tiles when you open the box, but this is not a serious problem for seafood (in fact, drying is more of a problem for seafood). ). However, if you still want to avoid this problem, you can place a pick (for example, six fibers) under the seafood (on the surface of the roof tile) for sashimi.

It is also possible to place the seafood directly on the tiles, but
You can first arrange bamboo leaves etc. on the tile and then place the seafood on top of it, or you can wrap the seafood in vinylidene chloride resin film, etc., or you can vacuum it up and then place it on the tile. good.

The "foamed plastic box" is not limited in any way in the present invention, and may be the same as a normal box that is often used these days because it is lightweight and has a large heat retention effect. The tiles mentioned above are stored in this box. Of course, you may also store other items in the box at the same time. For example, wasabi, a grater to grate it, soy sauce, etc. Of these, regarding the grater board, since the seafood itself is placed on the roof tile,
It would be interesting to use something made of ceramic that imitates the shape of an onigawara. Furthermore, the box made of foamed plastic may be provided with a partition for storing items other than roof tiles so that various items attached to the seafood can be put together with the seafood.

The refrigerated storage container of the present invention is designed to maintain the temperature of seafood when it is placed inside the container, but by the time the seafood is placed inside the box, the temperature inside the box is already below the temperature that the tiles are intended to maintain. Alternatively, it is desirable that the tiles are cooled. (Of course, you can refrigerate the seafood after placing it in the box, but in that case, deterioration in melting will continue until the temperature inside the box reaches the refrigeration temperature.) [Example] Implementation shown in the drawing below The invention will be explained in more detail on the basis of examples.

FIG. 1 shows one embodiment of a refrigerated storage container 1 according to the present invention, and as is clear from the figure, a box 2 made of expanded polystyrene (main body 21 and lid 22 )
and the tiles 3 therein.

This container 1 is for so-called home delivery in which seafood is delivered to a consumer's home in a refrigerated vehicle.

FIG. 2 shows a state in which four fillets 4 (for one fish) of actual flounder as seafood are placed on a roof tile 3 with bamboo leaves 5 interposed therebetween. This fillet 4 is for sashimi, and the wasabi 6 used to eat it as sashimi is bamboo!
It is housed within 37.

This tile 3 had been placed in a refrigerator at -2 degrees Celsius for more than 5 hours before the fillet 4 was placed on it.

Kawara 3 is a regular IffL for serving cooked seafood.
Since it is thicker and heavier than
It has a high cold retention effect, and when the inventor conducted a simple comparative experiment, it was found to be slightly inferior to those using ice, but slightly superior to those in which a bag-shaped bag containing a cold storage agent was kept at ice temperature.

FIG. 3 shows another embodiment of the present invention, which is characterized by the structure of the main body 21 side of the box 2 made of expanded polystyrene. That is, the main body 21 has not one storage section,
A storage section 23 for oroshi board 8 and a storage section 24 for wasabi 6 are each separated from a storage section 25 for tile 3 by a partition. As a result, there is no need to worry about the various items stored in the box 2 being disarranged during transportation, etc., and the storage work itself is simplified.

The oroshi board 8 is made of ceramic and imitates the shape of an oni tile, and is designed to have a design effect when stored alongside the tile 3. Further, although the oroshi side of the illustrated oroshi plate 8 is visible, when actually packing the items in boxes, it is better to turn the back side with the onigawara-like pattern (not shown) upward.

[Effects of the Invention] As explained in detail above, the refrigerated storage container according to the present invention is a container used for refrigerated storage of seafood, and includes a tile for placing the seafood and a tile for storing the tile. The invention is characterized by the fact that it is made of a foamed plastic box, and is an extremely advanced invention that has various effects as described below.

■ Since the tiles are thicker and heavier than regular ceramic tiles, they are highly effective when used as a cold insulation material.

■ Since the roof tile functions as a cold insulator, there is no need for ice or cooling agents, and the volume of the container can be reduced.

■ Since the tiles also function as plates for serving seafood, it can be a beautiful and innovative product.
