Description

[Detailed description of the invention] This invention relates to an improvement of a guard piece used for transporting live fish.

In view of the strong demand in recent years, the present inventor has proposed a rational and economical method for transporting marine products such as live fish (Special Publication No. 57-520).
1 inch), that is, in this method, as shown in Figure 1,
The target marine product 4 is transported by mixing it into a container 1 in which a number of pieces of hydrous foam material 3, which have a specific gravity smaller than that of ice, are immersed in water or sea ice 2, and the foam material pieces 3 are good. Due to the buffering effect and air replenishment effect, the fishery product 4 is characterized by very favorable conditions for survival and protection.

This method can be widely used for various types of seafood, but when transporting live fish 4 as shown in Figure 1, the only problem that needs to be improved is the following. It turned out.

This is because the live fish 4 become easily damaged due to friction between the foam material piece 3 used as a guard piece and the live fish 4.

Live fish 4 generally have so-called slime like mucus on their body surface to protect their living bodies.

On the other hand, the foamed material piece 3 is porous like a sponge, and has a rough surface as shown in an enlarged view in FIG.

However, during transportation, the two constantly come into contact with each other and rub against each other, which causes a phenomenon in which the necessary slime is taken away from the live fish 4, which in turn has a negative effect on the survival and protection conditions of the live fish 4.

In view of the above-mentioned problems, this invention was made for the purpose of providing an improved guard piece that can accurately eliminate the above-mentioned problems without degrading the original characteristics of the foamed material piece 3.

This idea will be explained in detail with reference to examples.

The guard piece according to this invention is constructed by covering a foamed material piece 3 with a film 5, as shown in FIG.

The foam material piece 3 is the same as that used conventionally, and a cut piece of polyurethane or the like is preferably used.

In the illustrated example, the foamed material piece 3 is shown as having a disk shape as an example, but its shape can be arbitrary, and its size can also be arbitrarily selected depending on the type of live fish 4, etc.

On the other hand, as for the film 5, any type of commercially available film material can be used as long as it has a smooth surface.

However, the film 5 covering the foamed material piece 3 must have through holes 6 and 7 at an appropriate number of locations to ensure smooth and effective contact between the foamed material piece 3 and water or sea ice 2 during use. is considered a necessary condition.

In the case of FIG. 3, a suitable number of round holes 6 are arranged on the upper and lower surfaces thereof, and the four corners are cut open and through holes 7 are also provided in these portions.

The shape, size, arrangement, etc. of the through holes 6, 7 may be changed as desired.

Next, regarding the method of covering the foam material piece 3 with the film 5, the film 5 and the foam material piece 3 may be packaged separately as shown in FIG. 4, or the film 5 and the foam material piece 3 may be packaged separately as shown in FIG. Similarly, the film 5 may be integrally applied to the surface of the foamed material piece 3.

As described above, since the guard piece according to this invention is made by covering a piece of water-containing foam material 3 with a film 5 having a smooth surface, this guard piece is used when transporting live fish 4 as shown in Fig. 1. If the container 1 is filled with the foam, the inconvenient problem caused by the foamed material pieces 3 and the live fish 4 rubbing against each other as described above can be accurately solved.

Further, since the film 5 is provided with through holes 6 and 7 at an appropriate number of locations, the original characteristics of the foamed material piece 3 are not impaired.

Therefore, by using the guard piece according to this invention, it is possible to solve the only drawback of the transportation method previously proposed by the present inventor, and it becomes possible to further contribute to the transportation of live fish 4 and the like.

In addition, to further explain the case where live fish 4 are transported by land in a state in which they are housed in a container 1 as shown in FIG. 1, as shown in FIG. It is reasonable to carry it.

At this time, rails 9 are placed on the container floor at appropriate intervals in advance.
9 is laid down, and on the other hand, wheels 10, 10 are attached to the container 1 used at the lowest level, and the containers 1, 1 are stacked in multiple tiers.
It would be convenient if the nursery surface could be moved.

The best way to place the containers 1 on the truck 8 is to arrange the live fish 4 parallel to the axle in order to reduce damage during transportation.
