The opening peripheral edge of the upper case member 10 and the outer peripheral edges of the inner side surfaces 22a-22d have substantially the same shape. Lower surface of lower case member 2
At a position almost close to the four corners of 1e, 4 protruding downward
Two legs 24 are formed. The leg portion 24, like the one shown in FIG. 2, has a portion sandwiched between two notches extending across the lower surface 21e of the lower case member 20 and the front side surface 20b or the rear side surface 20d adjacent to the lower surface 21e. It is also bent so that the folds are located inside and below the lower surface 20e. A claw fitting recess 23 having substantially the same shape as the claw portion 13 is formed at a position corresponding to the claw portion 13 of the upper case member 10 at substantially the center of the upper edges of the front inner side surface 22b and the rear inner side surface 22d. The outer end of the claw fitting recess 23 has a front outer surface 21b.
It is closed by the rear outer surface 21d.

The lower case member 20 has an inner surface 22a-2.
A fitting portion 30 that stands up from the upper edge of the inner side surfaces 22a-22d is formed along the upper edge of 2d. Fitting part 30
Has four fitting surfaces 30a-30d. The left fitting surface 30a is provided with a stopper 31 that slightly protrudes to the left at a position corresponding to the stopper hole 12 of the upper case member 10. As shown in FIG. 3, the stopper 31 is
It has a low-cylindrical shape, and the peripheral edge of the stopper 31 has substantially the same shape as the peripheral edge of the stopper hole 12. The upper end of the stopper 31 is formed obliquely toward the lower left. The upper edges of the left fitting surface 30a and the right fitting surface 30c, which are formed at positions corresponding to the short sides of the rectangular opening of the lower case member 20, are slanted downward from the center position to the front fitting surface 30b side. The front fitting surface 30b that is formed and is formed at a position corresponding to one long side of the rectangular opening of the lower case member 20 has upper edges thereof located above the left fitting surface 30a and the right fitting surface 30c.

The lower edge of the claw passing hole 32 has substantially the same length as the upper edge of the claw portion 13.

FIG. 4 is a perspective view showing a storage case with a lid according to the present invention with a lid attached.

As shown in FIG. 4, a storage case 1 with a main lid.
Fits the opening of the upper case member 10 to the fitting portion 30 so that the lower edge of the upper case member 10 is lower.
0 in a state of being supported in contact with the upper edge of the upper case member 10
Can be attached to the lower case member 20 as a lid of the storage case 1 with a lid. The upper edges of the left fitting surface 30a and the right fitting surface 30c, which are formed at positions corresponding to the short sides of the rectangular opening of the lower case member 20, are slanted downward from the center position to the front fitting surface 30b side. The front fitting surface 30b that is formed and is formed at a position corresponding to one long side of the rectangular opening of the lower case member 20 has upper edges thereof located above the left fitting surface 30a and the right fitting surface 30c. Since it is formed in a shape that is continuous with the front edge of the edge and is cut into a V shape from both ends toward the center, the upper case member 20 does not catch the upper edge of the lower case member 20 on the lower edge of the upper case member 10. It is possible to smoothly attach 10 to the lower case member 20. The V-shaped cut at the upper edge of the front fitting surface 30b also has an effect of facilitating the putting in and taking out of the article into and from the lower case member 20. As in the present embodiment, the V-shaped notch is preferably formed in the fitting surface formed at a position corresponding to one long side of the rectangular opening of the lower case member 20.

Although the stopper 31 protrudes leftward, it only slightly protrudes to about the thickness of the upper case member 10. In addition, the upper end of the stopper 31 descends obliquely leftward. Since it is formed in the above, the stopper 31 does not become an obstacle when the upper case member 10 is attached. And the stopper 31
Is fitted in the stopper hole 12 by attaching the upper case member 10 to the lower case member 20. By fitting the stopper 31 into the stopper hole 12, the upper case member 10 attached to the lower case member 20 cannot be removed, and the storage case 1 with the main lid can be lifted by holding only the upper case member 10. . Further, the stopper 31 is pushed inward, so that the left fitting surface 3 to which the stopper 31 is attached is attached.
Since 0a shifts inward, it is pushed inward from the stopper hole 12. When the stopper 31 is pushed inward from the stopper hole 12, the upper case member 10 attached to the lower case member 20 can be removed. Since the stopper hole 12 is formed so as to face both the left side surface 10a and the right side surface 10c of the upper case member 10, the upper case member 1
The upper case member 10 without paying attention to the left and right direction of 0.
Can be attached to the lower case member 20.

The storage case 1 with a main lid to which the upper case member 10 is attached has a rectangular parallelepiped shape as a whole. At positions near the four corners of the lower surface 20e of the lower case member 20,
Since the leg portion 24 protruding downward is provided, even if the lower surface 20e of the lower case member 20 is convex downward, the storage case 1 with a lid is placed on a flat table with the lower surface 20e facing downward. It can be placed in a stable state. Further, since leg portions 11 projecting upward are provided at positions substantially close to the four corners of the upper surface 10e of the upper case member 10, the upper case member 10 is also stable with the upper surface 10e facing downward. It can be placed on a flat table. Therefore, the storage case with a lid 1 is not only used as one storage case with a lid, but is also separated from the lower case member 20 with the lower surface 20e downward and the upper case member 10 with the upper surface 10e downward. It is also possible to use it as a storage case without a lid that opens above. Since the upper case member 10 and the lower case member 20 are transparent, it is possible to visually confirm from outside the storage case 1 with a lid or the articles stored in the upper case member 10 and the lower case member 20. It is possible.

Further, the storage case 1 with the main lid to which the upper case member 10 is attached has the outer side of the fitting portion 30 and the upper case member 10 so that the inside 1 of the storage case with the main lid is sealed.
The inner surfaces of the four side surfaces 10a-10d are in contact with each other. However, in reality, the front side surface 10b and the rear side surface 10d of the upper case member 10, which have the long side of the rectangular opening of the upper case member 10 as one side, bulge outward, so that the front side surface 10b of the upper case member 10 in particular bulges outward.
And the rear side surface 10d and the front side surface 20 of the lower case member 20.
b, rear side surface 20d, front fitting surface 30b and rear fitting surface 30
There is a gap between the storage case 1 and d, and the inside of the storage case 1 with the lid is not completely sealed. This problem is solved by the claw portion 13 and the claw hole 32. When the upper case member 10 is attached to the lower case member 20, as shown in FIG.
In addition, it is located outside the front outer surface 21b and the rear outer surface 21d. When the claw portion 13 is pushed inward, the claw portion 13 is displaced inward and upward, and is pushed into the claw passage hole 32. Then, when the pressing is stopped, the claw portion 13 tries to restore to the original position, but is blocked by the front outer side surface 21b and the rear outer side surface 21d of the lower case member 20 and is engaged with the claw passage hole 32. Then, it fits into the claw fitting recess 23 and stands still. Further, the outer end of the claw through hole 32 is provided on the front side surface 10 of the upper case member 10.
It is blocked by b and the rear side surface 10d. In such a state, the restoring force of the claw portion 13 always works, and the upper edge of the claw portion 13 that is going outward is closely contacted with the upper edges of the front outer surface 21b and the rear outer surface 21d, and The front side surface 10b and the rear side surface 10d of the upper case member 10 are prevented from bulging by the front side surface 20b and the rear side surface 20d of the lower case member 20. Therefore, the inside of the storage case with a lid 1 is completely sealed, and the shape collapse is prevented.

In the embodiment described above, the upper case member 1
The upper case member 10 is configured to be attached to the lower case member 20 by supporting the lower edge of the upper case member 20 in contact with the upper edge of the lower case member 20. May be configured so that the upper case member is attached to the lower case member by being supported in contact with the upper edge of the fitting portion, and at least two or more stoppers are provided in at least one pair of opposing fitting members. The upper case member may be attached to the lower case member by arranging them on the mating surface and fitting the stopper into the stopper hole.

Further, in the above-mentioned embodiment, the stopper 3
Although only one 1 is provided, a plurality of stoppers may be provided.

Further, in the above-described embodiment, the front ends of the upper edges of the left fitting surface 30a and the right fitting surface 30c are at the same height as both ends of the upper edge of the front fitting surface 30b. Although they are formed so as to be continuous with both ends of these, these front ends may be positioned higher than both ends of the upper edge of the front fitting surface.

Further, in the above-mentioned embodiment, the claw portion 13 is
It is formed on the lower edges of the front side surface 10b and the rear side surface 10d of the upper case member 10 which are the long sides of the rectangular opening of the upper case member 10, and correspondingly, the claw through holes 32 are formed on the front fitting surface 30b and the rear fitting surface. Although formed on the mating surface 30d, especially when the left side surface 10a and the right side surface 10c of the upper case member 10 whose short sides are the short sides of the rectangular opening of the upper case member 10 are also relatively large in width, The claw portions are also formed on the lower edges of the left side surface and the right side surface of the upper case member, and correspondingly, the claw through holes are also formed on the left fitting surface and the right fitting surface. good.
