Description

The present invention relates to a storage container suitable for maintaining the freshness of marine products and a method for preserving marine products using the same, particularly in the distribution stage including transportation and delivery.

Conventionally, as preservation methods for maintaining the freshness of marine products, there are used preservation methods such as a method of storing fishery products in a box such as a wooden box or styrofoam, and storing them frozen as they are, or a method of coexisting seafood and ice. However, in the method in which seafood and ice coexist in direct contact with each other, for example, the umami component of seafood is eluted in the melted ice, and the seafood absorbs water, and the freshness of the appearance is maintained to some extent. However, there was a problem that the original taste of seafood could not be maintained. In addition, in the case of preservation by ice cooling using fresh water ice or a mixture of seawater and ice, there is a problem that the freshness maintenance period is limited to 3 to 4 days in the case of seafood.

As one of the methods for solving the above problems, by using ice made of saline solution having a salt concentration equal to or lower than seawater, the difference between the osmotic pressure of fish and the melting temperature of ice can be reduced. There has also been proposed a method for maintaining freshness without deteriorating the taste of fish by bringing the temperature close to the ice temperature of the fish (see, for example, Patent Document 1 and Patent Document 2). However, for example, when transporting over long distances, the problem that the freshness of seafood falls due to the water that has melted from ice cannot always be sufficiently solved.

In order to maintain the freshness of the marine products at the distribution stage, such as transport and delivery, it is also possible to use a transport vehicle equipped with a cooling device for each container containing seafood. Of course, not only will it be expensive, but it will also increase the environmental burden and go against the recent global warming countermeasures.

Therefore, an object of the present invention is to provide a method for preserving the freshness of marine products, particularly in the distribution stage including transportation and delivery, by devising a container for marine products.

The object of the present invention is achieved by the following present invention described in claims 1 to 7 of the claims.

The invention described in claim 1 of the present invention includes a substantially rectangular parallelepiped box having an upper surface opened, a lid covering the opening of the upper surface, and a shape substantially similar to the lid in the box. A storage container for marine products comprising a shelf board disposed, the shelf board having a plurality of transmission holes, and a bottom surface that is less than half of the height (depth) of the side wall of the box A marine product storage container, characterized in that it is supported by a support portion provided on the side and can be detachably disposed in the internal space of the box.

The invention described in claim 2 is the marine product storage container according to claim 1, wherein a support portion for supporting the shelf board is provided on a side wall of the box.

The invention described in claim 3 is the marine product storage container according to claim 1, wherein a support portion for supporting the shelf board is provided on the back surface of the shelf board.

The invention described in claim 4 is the container for marine products according to any one of claims 1 to 3, wherein the lid body is provided with a number of vent holes.

The invention described in claim 5 is characterized in that a large number of air holes are provided in the side wall of the box on the upper surface side than half of the height (depth) of the side wall. 5. A storage container for marine products according to any one of 4 above.

According to the sixth aspect of the present invention, there is provided a substantially rectangular parallelepiped box having an upper surface opened, a lid covering the opening of the upper surface, and a shelf disposed in the box substantially in a similar shape to the lid. And a shelf provided with a plurality of transmission holes, and a support portion provided on the bottom side of half of the height (depth) of the side wall of the box The storage method of the seafood is characterized in that the seafood and ice are placed on the shelf plate of the storage container using the storage container supported by the container and disposed in the internal space of the box.

The invention described in claim 7 is the seafood preservation method according to claim 6, characterized in that seafood and ice containing salt are placed on a shelf plate of a storage container.

When the storage container for marine products of the present invention is used, even if the storage ice melts for long-term storage, the generated water falls from the perforation hole of the shelf to the lower space of the shelf and directly with the seafood. Since there is little contact, the freshness of marine products is maintained for a long time. Further, by using ice containing salt as ice, not only the ice melting time becomes longer than that of fresh water ice, but also the cooling temperature of the seafood can be lowered. In addition, since salt is also contained in ice and the water in which it is dissolved, there is a feature that the propagation of general bacteria can be suppressed. According to the present invention, the combination of these techniques provides effective and low-cost storage and transportation means for marine products, particularly in the distribution stage including transportation and delivery.

FIG. 1 is a schematic view of a vertical section of a container for marine products according to the present invention. FIG. 2 is a schematic diagram of a horizontal section of a storage container for marine products according to the present invention, and is a view for explaining a form of a shelf board. FIG. 3 is a schematic side view of the container for marine products of the present invention.

Hereinafter, the present invention will be described with reference to the drawings. FIG. 1 is a schematic view of a vertical section of a marine product storage container according to the present invention. 1 is a storage container, 2 is a lid, 3 is a shelf board, 4 is a lower space of the shelf board, 5 is a side wall, Represents a support part. The storage container includes a substantially rectangular parallelepiped shape whose upper surface is opened, that is, a rectangular parallelepiped or a box having a similar shape, and a lid for covering the opening. The lid body 2 only needs to have a function of covering the opening, and other shapes are not particularly limited. The material of the storage container 1 is not particularly limited, but wood, expanded polystyrene, and other plastics are suitable.

The shelf board 3 has a shape similar to that of the lid body 2 and is arranged inside the box body. The shelf board 3 is supported by a support portion 6 provided on the bottom side with respect to half of the height (depth) of the side wall of the box, and can be detachably disposed in the internal space of the box. Therefore, the support part 6 may be attached to the side wall of the box in a protruding shape, or may be attached to the back surface of the shelf in a foot shape. In any case, it is preferable that the support portion is integrally attached when the box body or the shelf board is molded.

FIG. 2 is a schematic diagram of a horizontal section of a storage container for marine products according to the present invention, and is a view for explaining a form of a shelf board. As shown in FIG. 2, the shelf board 3 has a large number of transmission holes. Moreover, since the shelf board 3 is supported by the support part 6 provided in the bottom face side rather than half of the height (depth) of the side wall of a box, the lower part of the shelf board 3 is a lower space (FIG. 1 (see 4). Therefore, a large number of transmission holes of the shelf board communicate with the lower space. In the present invention, since seafood and ice are placed and stored on the shelf 3 of the storage container, the water generated by the dissolution of the ice during storage passes through the perforation hole of the shelf 3 and the lower space of the shelf. It falls to (4 in FIG. 1) and is stored there. The number and shape of the permeation holes are not particularly limited. For example, a plurality of permeation holes having an arbitrary shape may be provided on a plastic plate such as foamed polystyrene, or a wire mesh. May be. It can be determined appropriately according to the type of marine products to be placed and stored.

Since the shelf 3 can be detachably disposed in the internal space of the box, the water accumulated in the lower space can be drained by removing the shelf 3 and tilting the box. . Or you may provide the hole with the water stop cock for draining in the bottom part of the box or the bottom part of the side.

FIG. 3 is a schematic side view of the marine product storage container of the present invention, and 5 represents a side wall. Reference numeral 7 denotes a vent provided in the side wall of the box on the upper surface side than half of the height (depth) of the side wall. In addition, the vent hole may be provided in the lid. The number and shape of such air holes are not particularly limited.

Another aspect of the present invention is a storage method in a distribution stage including transportation and delivery of marine products, characterized in that the storage container is used.
