Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a cold and waterproof package which can be cooled with ice during transportation in order to store fresh food or the like and maintain freshness.

[Conventional technology]

When transporting fresh food such as seafood by keeping it cold with ice,
It is usual to use a wooden box or a storage container formed of styrofoam.

In the case of the former, since the waterproof property is poor, a special device is required for the transportation means such as a truck and the cold insulation property is not sufficient.

The latter is difficult in terms of cost and is also a problem in terms of waste pollution.

[Challenges for devising]

In consideration of the above cost and waterproofness, it has been proposed to use a corrugated board with a waterproof treatment, but due to the structure of the corrugated board, it is easy to infiltrate from the cut end (end face),
The water that penetrates the water through the steps also quickly penetrates, which reduces the effect of waterproofing.

Then, the subject of this invention is to provide the structure of the package excellent in cold insulation and waterproofness using a corrugated cardboard box.

[Means for solving problems]

In order to solve the above problems, in the present invention, an assembled tray made of cardboard having a waterproof layer on the inner surface is housed in a cardboard box, and a water absorption pad is laid on the bottom wall of the tray.
The article was stored on the water absorbent pad and the structure was further filled with crushed ice.

[Action]

A waterproof layer is provided on the inner surface of the tray, and a water absorbing pad is laid on the inner surface of the tray, so that ice and moisture in the stored articles are absorbed and the cardboard box is protected.

In addition, the heat insulating property of the corrugated board itself can also maintain the cold insulation property.

〔Example〕

FIG. 1 shows a development sheet 10 'of a cardboard box. As shown, one end wall 11, one side wall 12, the other end wall 1
1'and the other side wall 12 'are continuous via folds 13, 14, 15 and a margin 17 is provided via the fold 16 at the edge of the other side wall 12'.

Further, common fold lines 18 and 18 'are provided at the upper and lower edges of the end walls 11 and 11' and the side walls 12 and 12 ', and these end walls and side walls are the inner flaps 19 and 19' of the bottom wall, respectively. Outer flap 2
0, 20 ', inner flaps 21, 21' of the top wall, outer flap 2
It is continuous with 2, 22 '.

To assemble the sheet 10 ', the glue margin 17 is connected to the outer edge of the end wall 11 with an adhesive or the like, the inner flaps 19, 19' of the bottom wall are bent along the fold line 18, and the outer flap 20, 20 'is overlaid on the inner flaps 19, 19' and fixed with adhesive tape or the like. FIG. 2 shows a completed AI type corrugated board 10. Of course, the configuration of the cardboard box is not limited to the above.

As shown in FIG. 3, a tray is provided on the inner surface of the bottom wall of the box 10.
40 is accommodated, and a water absorbing pad 30 is laid on the inner surface of the bottom wall of the tray 40. As shown in FIG. 4, the tray 40 is formed by stacking a thick paper 41 such as a corrugated board or a paperboard and a waterproof layer 42 made of a metal foil or a synthetic resin film alone or as a composite. As shown in FIG. 5, the tray 40 is continuous with a bottom wall 43, end walls 45 and 45 'continuous with the bottom wall 43 through folds 44 and 44', and folds 46 and 46 '. Side walls 47, 47 'and end wall and side wall connecting pieces 48, 4
Consists of 8 ', 49, 49'. As can be seen from the completed assembly drawing of FIG. 6, the four corners of the tray 40 are connected to the connecting pieces 48, 4
8 ', 49, 49' are continuous as one, so there is no risk of water leakage. The waterproof layer 42 is assembled on the inner surface of the tray 40.

As shown in FIG. 3, the water absorption pad 30 is laid on the bottom wall 43 of the tray 40 as described above, the article A such as seafood is stored on the water absorption pad 30, and the crushed ice B is further filled to complete the package C. To do.

As shown in FIG. 7, the water-absorbing pad 30 has pulp layers 32 and 32 'stacked on both sides of a water-absorbing polymer layer 31 and further sandwiched with water-absorbing papers 33 and 33' such as tissue paper to form a nonwoven fabric 34, The whole is covered with 34 '.

Note that the synthetic resin film layer 35 may be provided on the lower surface to retain the water absorbed by the water absorbing pad 30 and prevent the water from flowing out.

The water-absorbing pad 30 of FIG. 8 omits the pulp layers 32 and 32 ', and the water-absorbing pad 30 of FIG. 9 omits the polymer layer 31 and uses the pulp layer 32 as the core layer. In either case, a synthetic resin film layer 35 (not shown) can be provided on the lower surface thereof.

〔effect〕

According to this invention, as described above, the tray having the waterproof layer is housed on the inner surface of the bottom wall of the cardboard box, and the water absorption pad is laid on the bottom wall of the tray.
Allows a normal cardboard box to be used as a cool container,
Moreover, it exhibits an excellent effect of keeping cold. Further, since the tray is an assembling type using thick paper, an inexpensive one can be obtained, there is no fear of waste pollution, and handling such as storage and transportation is convenient.
