  In the present invention, it is an object to provide a storage box that can improve workability at the time of stacking and reduce the blank area.

To solve the above problems, accommodating box of the first invention is a receiving box which enables stacking arrangement of two or more, a bottom wall, continuous with the outer edge of said bottom wall, bent to the front Symbol bottom wall and an outer peripheral wall having obtained the wall, the bottom wall and for partitioning said wall portion, a cutting line extending from said bottom wall toward the wall, the bottom wall from the bottom wall end of the cutting line and a division line extending toward the perimeter of the wall portion and a recess inwardly with respect to the wall portion, a planar inclined wall extending obliquely between front Kisokokabe and the wall portion, front Stories in part by an end portion of the bottom wall side of the inclined wall is formed, a locking projection which projects outwardly from the bottom wall of the partition line as the top, and the bottom wall of the front Kigaishu wall opposite A locking receiving portion that protrudes inward from the end of the housing and that can be locked to the locking protrusion formed on the other edge of the other storage box. .

  When this storage box is assembled by bending the wall portion with respect to the bottom wall, the inner inclined wall defined by the cutting line and the dividing line extends in an inclined manner from the bottom wall to the wall portion of the outer peripheral wall. . This inclined wall has a total length obtained by adding the dimension S1 from the bottom wall side end of the cutting line to the boundary line with the wall part and the dimension S2 from the wall side end part of the cutting line to the boundary line with the wall part. It is. The total length of the inclined wall is larger than the hypotenuse dimension of a right triangle having a base dimension S1 and a height dimension S2. Therefore, the inclined wall partially extrudes the bottom wall, and a locking projection having a cutting line as a locking edge and a partition line as a top is formed on the bottom wall.

  When the storage boxes are stacked and stacked, the locking projections of the upper storage box are positioned between the locking receiving parts of the lower storage box, and when the upper storage box is moved laterally, the upper storage box The locking projection is locked to the locking receiving portion of the lower storage box. That is, since it is not necessary to accurately position and arrange the upper storage boxes to be stacked on the lower storage boxes, it is possible to improve the workability at the time of stacking. In addition, since the cutting wall and the dividing line can be provided on the wall portions of the bottom wall and the outer peripheral wall, and the inclined wall and the locking protrusion can be formed by assembly, the wall portion of the outer peripheral wall does not need to have a double wall structure. Therefore, the blank area can be reduced and the cost can be reduced.

In the tray of the first aspect of the invention, the wall has a recess formed by the front Symbol inclined wall, the tip edge of the front Kikabe portion fittable into the recess formed in the other housing box It is preferable to provide a convex part. In this way, the upper and lower storage boxes can be further positioned by fitting the concave and convex portions of the outer peripheral wall, so that the stability can be improved.

In addition, when fitting a convex part to the recessed part of an outer peripheral wall and positioning in a lamination | stacking state, it is good also as a structure which does not latch a latching protrusion to a latching receiving part. That is, the containing box of the second invention is a receiving box which enables stacking arrangement of two or more, and a bottom wall, said continuous outer edge of the bottom wall, the wall portion that is bent to the front Symbol bottom wall An outer peripheral wall having a cutting line extending from the bottom wall to the wall part in order to partition the bottom wall and the wall part, and from the end of the cutting line on the bottom wall side of the bottom wall and the wall part and a division line extending toward the boundary line, the depression inwardly with respect to the wall portion, a planar inclined wall extending obliquely between front Kisokokabe and said wall portion, said wall by the front Symbol inclined wall A concave portion formed in the portion, and a convex portion that is provided at a leading edge of the wall portion and can be fitted into the concave portion formed in another storage box .

In the storage box of the second aspect of the present invention, it is preferable that a locking step portion capable of locking the convex portion formed in the other storage box is further provided on the bottom wall side of the wall portion or on the bottom wall. In this way, since the locking performance of the upper and lower storage boxes can be improved, even when the recess of the concave portion due to the inclined wall is small, lateral displacement of the upper storage box can be reliably prevented.

  In the storage box of the present invention, the upper locking projections can be easily disposed between the lower locking receiving portions simply by stacking the storage boxes, so that the workability at the time of stacking can be improved. Moreover, since the inclined wall and the locking projection are formed by the cutting line and the partition line provided on the bottom wall and the wall part, and the wall part of the outer peripheral wall does not need to have a double wall structure, the blank area is reduced, Cost can be reduced.

The folding lines 14a to 14c are made of general-purpose ruled lines, and are provided so as to be positioned on a straight line in a region excluding the region where the inclined wall 15 and the locking piece 21 are formed. Specifically, the pair of inclined walls 15, 15 are formed at a predetermined interval from the center in the width direction, and a pair of locking pieces 21, 21 are provided adjacent to the outer sides of the inclined walls 15, 15. Yes. A folding line 14a is formed at the center in the width direction between the inclined walls 15 and 15, and folding lines 14b and 14c are provided outside the locking pieces 21 and 21, respectively.

  As shown in FIGS. 1 and 2, the inclined wall 15 extends in an inclined manner between the bottom wall 11 and the side walls 12 </ b> A and 12 </ b> B in an assembled state in which the side walls 12 </ b> A and 12 </ b> B are bent with respect to the bottom wall 11. Due to the inclined wall 15, a part of the bottom wall 11 protrudes outward to form a locking projection 16 that can be locked to the lower tray 10 </ b> A. Moreover, the recessed part 17 which can latch the convex part 25 of lower tray 10A is formed in side wall 12A, 12B. As shown in FIGS. 7 and 8, the inclined wall 15 is separated from the bottom wall 11 and the side walls 12 </ b> A and 12 </ b> B by a cutting line 18 extending from the bottom wall 11 to the side walls 12 </ b> A and 12 </ b> B, and from both ends of the cutting line 18. 1st and 2nd division line 19 and 20 extended toward the edge part of the folding line 14a which is a boundary line are provided.
