DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a container for storing fish and shellfish in an appropriate amount.

[0002]

2. Description of the Related Art Generally, fish and shellfish such as firefly squid, Japanese squid, sea cucumber, and squid are placed on a distribution route in a boiled state. In this case, as a container in this case, a plurality of wooden boxes each having a size of about 30 cm square were conventionally stacked in a plurality of stages, but now, plastic containers such as polypropylene are widely used in place of the wooden boxes.

[0003] As a container for storing the fish and shellfish,
First, fish and shellfish are subdivided into the container, and a plurality of these are stacked, immersed in boiling water and boiled, and may be flown directly to the distribution route. In this case, thin paper is laid on the bottom surface of the container and placed on the thin paper.

[0004]

However, when thin paper is laid on the bottom surface of the container, the boiled fish and shellfish can be placed in the container or after the container has been placed in the container.
There was a problem that the thin paper slipped. This is because the height of the container itself is low and the thin paper has no stiffness, so that there is a drawback that the seafood placed and stored is shifted due to sticking out or bending from the container. This is particularly noticeable when the number of containers is small, which is a factor that hinders commercial value.

[0005]

In view of the above-mentioned problems, the present inventor has made the present invention as a result of intensive studies. The features of the present invention are that a bottom surface and the periphery of the bottom surface are provided. Thin paper is laid on the bottom surface of the tray body formed by the side wall provided, and fish and shellfish are placed and stored on the thin paper in an appropriate amount, and the side wall has an opening communicating with the bottom surface, and That is, a protrusion is provided on the bottom surface to be inserted into a hole provided in the thin paper.

[0006] The "tray main body" as used herein refers to a container having a rectangular bottom surface surrounded by a side wall which is an erect surface. An opening is provided in the side wall of the tray body over the entire circumference. The opening is provided at a position communicating with the bottom surface of the tray body, and functions as a drain to prevent water from collecting on the bottom surface. It is also preferable that holes are formed in the bottom surface itself at appropriate intervals, or that the bottom surface is drained in a colander shape. Further, since thin paper is laid on the bottom surface, ridges and projections may be provided to provide a gap between the bottom surface and the thin paper to enhance the drainage function. In this case, the ridges or the like may be provided in a grid pattern to position the firefly squid or the like to be placed and prevent displacement.

In the tray according to the present invention, one or more projections are provided on the bottom surface of the tray body. These projections prevent slippage of the thin paper by being inserted into holes provided in the thin paper laid on the bottom surface. In this case, the relationship between the diameter of the projection and the diameter of the hole does not need to completely prevent the displacement of the thin paper.Therefore, when the thin paper is laid on the bottom surface, the projection can be easily inserted into the hole to improve workability. It is preferable not to inhibit it. The number of protrusions may be appropriately increased or decreased according to the size of the tray main body. However, basically, providing only one at the center of the bottom surface has a sufficient effect in preventing displacement of thin paper.

Although the height of the projection is about 3 mm works well, it is preferable that the height is 5 mm or more so that the projection does not fall out of the hole even when the thin paper is warped or bent. The shape of the projection may be any shape such as a cone, a truncated cone, a polygonal prism, a cylinder, an elongated plate or a cross in addition to a column.

The basic shape of the tray body may be any shape such as a simple container shape or a shape in which a flange is provided at the upper end of the side wall. The size is also free and not limited, but is generally 50 × 100 mm to 200 mm.
X 400 mm. Further, the thickness and the material may be any as long as the object of the present invention is achieved.

[0010] "Thin paper" is a sheet-like sheet laid on the bottom of the tray body, on which fish and shellfish such as firefly squid are placed. As the thin paper, for example, parchment paper is generally used, but nonwoven fabric or Japanese paper may be used. In the present invention, a thin paper having a hole is used to fit into a projection provided on the tray body so as not to be displaced. The holes are provided in correspondence with the number and positions of the projections provided on the tray main body, but a plurality of holes may be provided so as to be inserted into holes at appropriate positions. In this case, there is an effect that it is possible to easily cope with trays having different numbers and positions of projections. The shape of the hole may be formed in the same manner as the cross-sectional shape of the protrusion described above, but may be made to a somewhat rough shape so that the protrusion can be easily inserted. The size may be such that a plurality of adjacent protrusions can be inserted.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail based on embodiments shown in the drawings.

FIG. 1 shows an embodiment of a tray 1 according to the present invention.
Is established. The side wall 5 of the tray main body 2 is provided with an opening 6 communicating with the bottom surface 3 over the entire circumference so that water does not accumulate on the bottom surface 3. In addition, bottom 3
Also, a plurality of through holes 7 are provided to drain water.
Then, a plurality of ridges 9 are provided on the bottom surface 3 so as to create a gap between the thin paper 8 and the bottom surface 3 when the thin paper 8 is laid. The tray 1 shown in this example is about 200 × 100
It is made of polypropylene having a thickness of about 20 mm and a thickness of about 1 mm. The trays 1 are provided at four corners for supporting the upper tray 1 when the trays 1 are stacked.

The tray 1 has holes 11 as shown in FIG.
Is laid on the bottom surface 3 with the projections 4 inserted through the holes 11 and firefly squid is placed and stored on the thin paper 8 and placed on the distribution route. Accordingly, the thin paper 8 is held without being displaced on the bottom surface 3 by the hole 11 formed in the thin paper 8 engaging with the projection 4, and thus, it is possible to prevent the placed and stored firefly squid from shifting. Becomes

Usually, the tray 1 of the size of the above-described embodiment is used.
As shown in FIG. 3, for example, three units are connected to each other, put on a distribution route as a set, and are separated when sold to general consumers and the like. In this case, the connecting means may be provided by providing an engaging means such as a hook or a protrusion on the side wall 5 or the flange of the tray main body 2 for connection, or a plurality of pieces may be easily separated when the tray 1 is injection-molded. They may be integrally molded, folded by hand, or cut with a knife or the like to separate them.

In addition to providing only one protrusion 4 at the center of the bottom surface 3, two protrusions may be provided as shown in FIG. 4A to more securely hold the thin paper 8. Alternatively, the thin paper 8 may be formed in a plate shape as shown in FIG. In this case, as shown in FIG. 3C, the columnar projections 4 may be provided close to each other, the long holes 11 may be formed in the thin paper 8 and fitted into the two projections 4.

Further, as shown in FIG.
Can be made to correspond to any tray 1 in which the position of the projection 4 is different.

[0017]

As described above, the tray according to the present invention has a structure in which projections are erected on the bottom surface and thin paper with holes is engaged with the projections to be laid, or the projections are formed on the bottom surface. By laying the thin paper with holes in the standing tray body by engaging with the protrusions, it is possible to prevent the thin paper from shifting, so that the seafood such as firefly squid can be put in the tray or transported. It has an extremely useful effect in practical use, for example, when the fish and shellfish are not deviated in the tray.
