Abstract

PURPOSE: To prevent a thin paper from slipping from a bottom surface and prevent sea foods put on the thin paper from being displaced by forming an opening in a side wall of a tray body so as to communicate with the bottom surface and erecting on the bottom surface a protrusion for insertion into an opening of the thin paper. CONSTITUTION: In a tray 1, a protrusion 4 is erected at the center of a bottom surface 3 of a tray body 2. And openings 6 in communication with the bottom surface 3 are formed in side walls 5 of the body 2 over the entire surfaces thereof to prevent water from remaining on the bottom surface 3. Further a plurality of through holes 7 are formed in the surface 3 to discharge water. And a plurality of protruding strips 9 are formed on the bottom surface 3 to form a gap between the bottom surface 3 and a thin paper 8 when the paper 8 is laid on the surface 3. That is, in the tray 1, the protrusions 4 are inserted into holes 11 of the paper 8 to lay the paper 8 over the surface 3 so that sea foods are placed and stored on the thin paper 8. Thus by engaging the protrusions 4 with the holes 11, the paper 8 is prevented from being displaced from the bottom surface 3 and hence the sea foods are prevented from slipping.

Description

Detailed Description of the Invention

[0001]

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

[0002]

2. Description of the Related Art Generally, seafood such as firefly squid, squid, coconut, and pearl oyster is boiled and placed on a distribution route. As a container in this case, a wooden box having a size of about 30 cm square has been conventionally used to be stacked in a plurality of stages, but at present, a plastic container such as polypropylene is widely used instead of the wooden box.

As a container for containing the seafood,
First, seafood is subdivided into the container, a plurality of these are stacked, immersed in boiling water and boiled, and sometimes they are flowed to the distribution route as they are. 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, even when the boiled seafood is put in the container or after being put in the container,
There was a problem that the thin paper would be misaligned. This is because the height of the container itself is low and the thin paper is not stiff, and there is a drawback that the seafood stored and stored is biased because the container is bent or bent. This becomes remarkable especially when the number of containers is small, which is also a factor that hinders the commercial value.

[0005]

Therefore, the present inventor has achieved the present invention as a result of earnest research in view of the above problems, and is characterized in that it is provided on the bottom surface and around the bottom surface. Thin paper is laid on the bottom surface of the tray main body composed of the side walls, and an appropriate amount of seafood is placed and stored on the thin paper, and the side wall has an opening communicating with the bottom surface. It is because a protrusion is provided on the bottom surface so as to be inserted into a hole provided in the thin paper.

As used herein, the term "tray body" refers to a container in which a rectangular bottom surface is surrounded by side walls which are standing surfaces. An opening is provided on the side wall of the tray body over the entire circumference. This opening is provided at a position communicating with the bottom surface of the tray body, and functions as a drainer so that water does not collect on the bottom surface. In addition, it is preferable that holes be formed at appropriate intervals on the bottom surface itself, or it be formed in a colander shape so that water can be drained. Further, since a thin paper is laid on the bottom surface, a protrusion or a protrusion 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 and the like may be provided in a grid pattern so as to position the firefly squid and the like to be mounted and prevent displacement.

In the tray according to the present invention, one or a plurality of protrusions are provided upright on the bottom surface of the tray body. The protrusions prevent the deviation of the thin paper by being inserted into the holes provided in the thin paper laid on the bottom surface. In this case, since the relationship between the diameter of the projection and the diameter of the hole does not need to completely prevent the deviation of the thin paper, when the thin paper is laid on the bottom, the projection is easily inserted into the hole to improve workability. It is preferable not to interfere. The number of projections may be appropriately increased or decreased according to the size of the tray main body, but basically providing only one at the center of the bottom surface is sufficiently effective in preventing the deviation of thin paper.

Further, the height of the projections of about 3 mm is sufficient, but it is preferable that the projections do not come out of the holes even if the thin paper is warped or bent by setting the height to 5 mm or more. Since a plurality of trays are used by stacking, if the height of the top of the protrusion contacts the bottom of the tray when stacked, the bottom can be supported by the protrusion, and the size of the tray increases. It is more effective in preventing the tray from bending. In this case, a recess or a protrusion may be provided on the back surface side of the bottom surface of the portion where the protrusion is provided, and the top of the protrusion and the recess or protrusion may be engaged when the trays are stacked. The shape of the protrusion may be any shape such as a conical shape, a truncated cone shape, a polygonal prismatic shape, a cylindrical shape, an elongated plate shape, or a cross shape, in addition to a cylindrical shape.

The basic shape of the tray body may be any shape such as a simple container shape or one having a flange at the upper end of the side wall. The size is also free and not limited, but generally 50 × 100 mm to 200
It is in the range of × 400 mm. Further, the thickness and the material may be any as long as they meet the purpose of the present invention.

The "thin paper" is a sheet-like material laid on the bottom of the tray body, on which seafood such as firefly squid is placed. As the thin paper, for example, sulfuric acid paper is generally used, but non-woven fabric or Japanese paper may be used. In the present invention, a thin paper sheet having holes is used so that the thin paper sheet is fitted into the protrusion provided on the tray body so as not to be displaced. The holes are provided so as to correspond to the number and positions of the protrusions provided on the tray body, but a plurality of holes may be provided so that the holes can be inserted into the 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 protrusions. The shape of the hole may be the same as the cross-sectional shape of the protrusion described above, but may be roughly rough to some extent so that the protrusion can be easily inserted. The size may be such that a plurality of adjacent protrusions are inserted.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the embodiments shown in the drawings.

FIG. 1 shows an embodiment of a tray 1 according to the present invention, in which a protrusion 4 is formed at the center of a bottom surface 3 of a tray body 2.
Was erected. The side wall 5 of the tray body 2 is provided with an opening 6 communicating with the bottom surface 3 over the entire circumference so that water does not collect on the bottom surface 3. Also, the bottom surface 3
Also, a plurality of through holes 7 are provided for draining.
A plurality of ridges 9 are provided on the bottom surface 3 so that a gap is created 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 and has a depth of about 20 mm, a depth of about 20 mm, and a thickness of about 1 mm. When the trays 1 are stacked, the receiving portions 10 for supporting the upper trays 1 are provided at the four corners.

This tray 1 has holes 11 as shown in FIG.
The thin paper 8 having the holes formed therein is laid on the bottom surface 3 by inserting the projections 4 into the holes 11, and the firefly squid and the like are placed and stored on the thin paper 8 and placed on the distribution route. Therefore, the thin paper 8 is held on the bottom surface 3 without being displaced by the holes 11 formed in the thin paper 8 engaging with the projections 4, and thus it is possible to prevent deviation of firefly squid or the like placed and stored. Becomes

Normally, the tray 1 having the size of the above-mentioned embodiment is used.
For example, as shown in FIG. 3, for example, three pieces are connected to each other, and they are put on a distribution route as a set, and are separated when they are sold to general consumers and the like. As the connecting means in this case, engaging means such as hooks and protrusions are provided on the side wall 5 and the brim portion of the tray main body 2 so as to connect them, or a plurality of trays can be easily separated when injection-molding. It may be integrally molded and may be folded by hand or cut with a knife or the like to be separated.

The protrusion 4 may be provided only at the central portion of the bottom surface 3 or may be provided at two places as shown in FIG. 4 (a) so that the thin paper 8 can be held more reliably. Alternatively, the thin paper 8 may be prevented from rotating as shown in FIG. In this case, cylindrical protrusions 4 may be provided close to each other as shown in FIG. 7C, and a long hole 11 may be formed in the thin paper 8 to be fitted into the two protrusions 4.

As shown in FIG. 5 (a), the protrusion 4 is a bottom surface 3 of the tray 1 which is located at the top when the trays 1 are stacked.
When the height of the tray 1 is set to be in contact with the tray 1, the protrusion 4 supports the central portion of the tray 1 to prevent the tray 1 from bending. In this case, a recess 12 is provided on the back surface side of the portion where the projection 4 is provided as shown in FIG.
It is also possible to engage the top of the protrusion 4 to prevent lateral movement. If a plurality of recesses 12 are provided at appropriate intervals, it is possible to accommodate trays 1 having different positions of the protrusions 4. This also applies to the thin paper 8, as shown in FIG.
If the holes 1 are provided, it is possible to correspond to any tray 1 having different positions of the protrusions 4.

[0017]

As described above, the tray according to the present invention has the structure in which the projection is erected on the bottom surface and the thin paper having the holes is laid so as to engage with the projection, whereby the deviation of the thin paper is prevented. Since it can be prevented, the seafood such as firefly squid is not biased in the tray when it is put in the tray or when it is transported. Further, when the trays are stacked, the protrusions support the bottom surface of the tray located at the upper portion, so that the trays can be prevented from warping, bending, or moving in the lateral direction. It has various effects.
