Description

[Detailed Description of the Invention] The present invention relates to a fresh fish box used for packing fish caught on a fishing boat or the like and transporting the box to the market.

As is well known to those skilled in the art, the fresh fish box as described above is
A fresh fish box is made up of a box-shaped main body made of foamed synthetic resin with an open top, and a lid body also made of foamed synthetic resin and detachably fitted onto the main body to cover the opening of the main body. It is widely used in practical applications.

However, in conventional fresh fish boxes, the lid is made of foamed synthetic resin such as foamed polystyrene like the main body and is opaque, so when the lid is fitted onto the main body, the fish cannot be stored inside the fresh fish box. It is not possible to observe the fish etc.

On the other hand, when buying and selling fish, etc. at a market, etc., it is necessary to observe the fish, etc., and for this purpose, it is necessary to remove the lid from the main body and open the opening of the main body.

However, if the fish stored in the fresh fish box is, for example, squid, each time the lid is removed from the main body and the inside of the main body is exposed to the outside air, the squid changes color and the product value decreases. .

Therefore, when negotiating the sale and purchase of fish stored in a fresh fish box, there has been a need to be able to fully observe the fish without removing the lid from the main body.

In order to meet this demand, Utility Model Application No. 128540/1985 filed by the present applicant discloses a box-shaped body made of foamed synthetic resin having a bottom wall and four side walls and an open top surface; A fresh fish box has been proposed that includes a transparent or translucent synthetic resin sheet lid that is removably fitted over the main body and covers the opening of the main body.

Therefore, on fishing boats, markets, etc., multiple fresh fish boxes are often stacked vertically, but since the lids of the fresh fish boxes mentioned above are made of synthetic resin sheets, when stacked vertically, the lids are stacked vertically. There is a tendency for the peripheral edge of the lid to warp or come off from the side wall of the main body when a force is applied to press the body downward or to move it laterally.

Furthermore, since the lid is made of a synthetic resin sheet that has poor heat insulation properties compared to foamed synthetic resin such as foamed polystyrene, there is also the problem that it is difficult to maintain the inside of the fresh fish box in a cooled state.

The present invention was developed in view of the above circumstances, and its purpose is to make it possible to observe fish, etc. inside the main body even when the lid remains attached to the main body, and to make the lid sufficiently strong. An object of the present invention is to provide a fresh fish box that is improved so as to satisfy the requirements of having heat insulation properties.

According to the present invention, there is provided a box-shaped main body made of foamed synthetic resin having a bottom wall and four side walls and an open top surface, and a box-shaped main body made of foamed synthetic resin that is removably fitted onto the main body and covers the opening of the main body. The lid includes a foamed synthetic resin lid having an opening, and a transparent or translucent synthetic resin sheet covering the opening of the lid, and a groove is formed around the opening of the lid, On the other hand, the peripheral edge of the sheet that covers the opening of the iron lid body is formed into a substantially U-shaped cross section, and the edge of the peripheral edge is bent outward in a hook shape. by fitting into the groove so that the edge of the peripheral portion does not dig into the inner wall of the ridge,
There is provided a fresh fish box characterized in that the sheet is locked to the lid.

In a preferred embodiment of the fresh fish box according to the present invention, the edge of the sheet is preferably formed continuously over the entire periphery of the sheet, and further, the inner wall of the ridge is on the side of the periphery of the lid. It is preferable that the lid body stand upright and that the center side of the lid body is inclined downwardly and outwardly.

Hereinafter, a specific example of a fresh fish box constructed according to the present invention will be described in more detail with reference to the accompanying drawings.

Explaining with reference to FIGS. 1 to 3, especially FIG. 1,
The illustrated fresh fish box, which is designated as a whole by number 2, is composed of a main body 4 and a lid 6 that is detachably fitted onto the main body.

The main body 4 made of foamed synthetic resin, which is made by foam molding foamable synthetic resin beads such as foamable polystyrene beads, has a bottom wall 8 and four side walls 10.12, 14.16.
It is box-shaped as a whole, and the top surface is open.

As shown in FIGS. 1 to 3, a rectangular notch 18 is formed in the middle of the outer surfaces of the side walls 14 and 16, into which the fresh fish box 2 can be placed. .

Furthermore, a protrusion 20 defined by a protrusion extending along the peripheral edge of the bottom wall 8 is formed on the lower surface of the bottom wall 8, as shown in FIGS. 2 and 3.

It is important that the protrusion 20 has a contour corresponding to the inner contour of a protrusion formed on the upper peripheral edge of the lid 6, which will be described later.

Furthermore, it is advantageous for at least one drainage hole 22 to be formed in each of the inner parts of the bottom wall 8, i.e. in the parts adjacent to the side walls 10 and 12.

In the illustrated example, there are four drainage holes 22 in total, two on each side of the bottom wall 8 at appropriate intervals in the longitudinal direction.
(only two of which are shown in FIG. 1).

These drainage holes 22 extend through the bottom wall 8 and the protrusion 20 provided on the lower surface thereof, and are open not only on the lower surface of the protrusion 20 but also on the outer surface thereof.

Next, the lid body 6 will be explained. In the illustrated example, the lid body 6 made of foamed synthetic resin is manufactured in the same manner as the main body 4. As can be understood from FIG. 2 and FIG.
It is made of a foamed synthetic resin plate having the same shape as the outside of the upper surface of the side walls 10, 12, 14. A protrusion 24 is formed.

Further, on the upper peripheral edge of the lid body 6, at each of the four corners and the intermediate portion in the longitudinal direction, a raised portion 26 has an inner contour corresponding to an outer contour of the protruding portion 20 formed on the lower surface of the main body 4. is formed.

The lid body 6 is made of foamed synthetic resin as described above, and a part thereof is provided with an opening, and a transparent or translucent synthetic resin sheet is placed in the opening to form a viewing window. is important.

As the transparent or translucent synthetic resin sheet, for example, a vinyl chloride sheet, a biaxially oriented polystyrene sheet, etc. are used.

In the illustrated example, two openings 28 and 30 are provided in the center of the lid 6, and these two openings 28 and 30 are provided on the outside.
Groove 3 along a substantially rectangular shape surrounding two openings 28 and 30.
2 is formed, and a transparent synthetic resin sheet 34 having the same rectangular shape as this groove 32 is fixed to the lid body 6 by fitting its peripheral edge 36 into the groove 32 to form a viewing window 38. .

The peripheral edge 36 of the synthetic resin sheet 34 has a substantially U-shaped cross section as shown in an enlarged view in FIG. It is bent into a shape.

Therefore, when forming the viewing window 38, when the peripheral edge part 36 of the synthetic resin sheets 1 to 34 is pushed into the groove 32 of the lid body 6, the peripheral edge part 36 having a U-shaped cross section fits into the groove 32, and The hooked edge 36 a is on the outside of the groove 32 (peripheral side of the lid 6)
It bites into the inner wall.

As a result, the peripheral edge portion 36 is held in place in the groove 32 so as not to come off, and the synthetic resin sheet 34 is fixed in a state covering the openings 28 and 30 of the lid body 6.

In this way, the sheet 34 is easily fitted into the groove 32 of the lid 6 by its U-shaped peripheral edge 36, and is securely held in the lid 6 by the hook-shaped edge 36a after fixing. be.

In addition, the hook-shaped edge 36a is attached to the sheet 3 as in the illustrated example.
It is preferable that the grooves be formed over the entire circumferential edge 36 of No. 4, but may be formed intermittently at appropriate intervals along the circumferential edge 36.

On the other hand, the groove 32 of the lid 6 is formed in the lid 6 as shown in FIG.
It is preferable that the inner wall 32a on the peripheral side stands upright, and the inner wall 32b on the center side slopes downward (i.e., toward the bottom) to the outside.

This makes it easier for the peripheral edge 36 to enter the groove 32 when attaching the synthetic resin sheet 34, and the hooked edge 3
6a bites into the inner wall 32a at a substantially right angle, resulting in an effect of more secure locking.

Further, the shape and size of the opening formed in the lid 6 may be arbitrary as long as the fish etc. housed in the main body 4 can be observed when the lid 6 is fitted onto the main body 4. In the case of a rectangular opening extending in the longitudinal direction corresponding to the shape of the fresh fish box, it is best to divide it in the middle and make the opening the second-largest one, as shown in the specific example shown, in terms of the strength of the viewing window. preferable.

In the fresh fish box 2 as described above, fish caught on a fishing boat or the like are usually stored in the main body 4 together with ice.

Then, as shown in FIGS. 2 and 3, the lid 6 is attached to the main body 4.
is fitted to close the opening of the main body 4, but at that time, the protrusion 24 formed on the lower surface of the lid 6 comes into contact with the upper part of the inner wall of the opening of the main body 4, so that the lid 6 does not shift relative to the main body 4. Positioned in

In addition, when a plurality of fresh fish boxes 2 are stacked, a protrusion formed on the lower surface of the main body 4 of the upper fresh fish box is placed inside the raised part 26 formed on the upper surface peripheral edge of the lid 6 of the lower fresh fish box. The portions 20 are positioned in abutment.

Therefore, the upper fresh fish box 2 is prevented from moving in the lateral direction relative to the lower fresh fish box 2, and a plurality of fresh fish boxes 2
The stacking in the vertical direction is maintained stably.

In this case, the water generated by melting the ice stored in the fresh fish box 2 along with the fresh fish etc. flows out through the drain hole 22 of the main body 4, but the water that flows out from the fresh fish box 2 above is the upper raised part 26 of the lid 6 of the lower fresh fish box 2.
is discharged laterally through a discharge channel defined between.

Therefore, in the fresh fish box as described above according to the present invention,
An opening of an appropriate size is provided in the foamed synthetic resin lid 6 that is fitted onto the foamed synthetic resin main body 4, and this opening is covered with a transparent or translucent synthetic resin sheet 34 to form a viewing window 38. , it is possible to observe the fish inside the main body 4 while the lid 6 is still attached to the main body 4 without substantially reducing the strength and insulation properties of the lid 6, and cooling of fresh fish is possible. The condition can also be maintained well.

Further, a groove 32 is formed around the opening of the lid body 6, and a peripheral edge 36 of the other sheet 34 is formed to have a substantially U-shaped cross section so as to fit into the groove 32, and an end of the peripheral edge 36 is formed. Edge 3
6a is bent outward in a hook shape, so when covering the opening of the lid 6 with the sheet 34, it is only necessary to push the peripheral edge 36 of the sheet 34 into the groove 32 of the lid 6. As a result, the edge 36a bites into the inner wall 32a of the groove 32, and thus the sheet 34 can be easily installed and securely held.
