2. Description of the Related Art A storage box made of a good heat conductor such as stainless steel is installed at intervals in a heat insulation box which is an outer box of a refrigerator, and cold air is circulated between the heat insulation box and the storage box. As shown in FIG. 4 , a conventional storage box 1 includes a ceiling panel 2, a rear panel 3, a side panel 4, and an indirect cooling system that cools foods from the outside and indirectly cools foods and the like in a high humidity atmosphere . 5 and a bottom panel 6, which are connected to each other by screws 7 to be assembled in a box shape, and a front surface which is opened and closed by a heat insulating door (not shown) is opened.

In this case, one of the panels connected to each other has a flange 10 formed by bending the side edges, and the other panel has a side edge 11 of a flat plate which is not bent and is superposed and screwed. As illustrated in FIG. 5 , the food or the like in the storage box 1 may be the side edge portion 11 of the side panel 5.
When it is strongly hit or pressed against a portion adjacent to, as shown by an arrow A, the side edge portion 11 is deformed outward between the screws 7 to form a gap 12, and the inner corner portion The caulk 13 may be peeled off.

Therefore, the dry cold air that cools the outer surface of the storage box 1 flows into the storage box 1 through the gap 12 to dry the food and the like in the storage box 1 and impair its quality.
The drainage in the storage box 1 flows out from this gap 12, and the storage box 1
Of the heat-insulating box which is not shown in the figure and accumulates at the bottom of the heat-insulating box to block the cold air passage between the bottom of the heat-insulating box and the bottom of the storage box 1 to block the flow of cold air and prevent the cooling of the outside of the storage box 1 by the cool air. There was a risk of causing a serious malfunction as a refrigerator.

In order to solve the above-mentioned problems, it is conceivable to increase the number of screws 7 and reduce the pitch of the screws 7, but the assembly work of each panel is complicated and impractical. If the plate thickness is increased so as not to deform the panel, each panel becomes heavy and the assembly workability is deteriorated from this aspect, and in any case, the cost is increased.

It consists of The ceiling panel 22 is provided with screw holes 28 on both sides and a rear side of the flat plate portion 32, and bent edges 42 bent downward are provided on the outer sides of the screw holes 28.

In the rear panel 23, four side edges are bent rearward to form flanges 53, and each flange 53 is formed.
A screw hole 28 is formed in the. The right side panel 24 is
A screw hole 28 is formed in the rear of the flat plate portion 34, and a bent edge 44 bent leftward is provided behind the flat hole 34, and the front and upper side edges are bent rightward to form a flange 54. Are formed, and screw holes 28 are formed in the upper and lower flanges 54.

The left side panel 25 has a screw hole 28 formed in the rear of the flat plate portion 35, and a bent edge 45 bent rightward is provided behind the flat plate portion 35, and front and upper side edges. Is bent leftward to form a flange 55, and screw holes 28 are formed in the upper and lower flanges 55. The bottom panel 26 has flanges 56 formed by bending both side edges and rear side edges outward, and each flange 56 is provided with a screw hole 28.

The above-mentioned panels 22, 23, 24, 25, 2
6 aligns the screw holes 28 with each other, and
The storage box 21 is assembled by the above, but as illustrated in FIG. 3, when the end edge of the flange 53 of the rear panel 23 is applied to the inside of the bent edge 45 of the left side panel 25, the flange 53 and the left side panel 25 are arranged. Screw hole 2 with flat plate part 35
8 is almost the same. Reference numeral 60 denotes caulking provided on the inside corners after the panels 22, 23, 24, 25 and 26 are assembled.

The storage box 21 has flanges 53 on a rear panel 23, a right panel 24 and a left panel 25,
54 and 55 have a ceiling panel 22 and a right side panel 2 respectively.
