Then, as shown in FIGS. 7A and 8A, when the slide engaging protrusion 46 is arranged at the end of the guide recess 28 away from the long side wall 13, the slide engaging protrusion 47 is formed. Facing the first recess 23, as shown in FIG. 6, the amount of overlap between the locking surface 47B of the slide engaging protrusion 47 and the lower surface of the upper end flange 17 in the vertical direction is small. As a result, the outer hanging piece 45 can be elastically deformed slightly outward, and the raising member 40 can be attached to and detached from the box-shaped container 11. Hereinafter, the position of the raising member 40 at this time is referred to as a "temporary mounting position".

As shown in FIG. 4 (B), the locking protrusion 48 extends in the vertical direction along the edge of the end portion of the outer hanging piece 45 on the side distant from the expansion portion 49 in the longitudinal direction. Further, the planosection shape of the locking protrusion 48 is trapezoidal, and a locking surface 48B orthogonal to the longitudinal direction of the outer hanging piece 45 is provided on the slide engaging protrusion 47 side, while the outside is provided on the opposite side. An inclined surface 48A that is inclined with respect to the longitudinal direction of the hanging piece 45 is provided. Then, as shown in FIG. 8A, when the raising member 40 is arranged at the temporary mounting position, the locking protrusion 48 is received by the second recess 24 of the box-shaped container 11 and slide-engaged from there. When the raising member 40 is slid so as to bring the protrusion 46 closer to the long side wall 13, the slope 26A of the trapezoidal protrusion 26 next to the second recess 24 of the box-shaped container 11 and the slope 26A of the locking protrusion 48 are inclined. The outer hanging piece 45 is elastically deformed by sliding contact with 48A.

On the opposite side, there is an inclined surface 61A that is inclined with respect to the lower surface of the raised main body 51. While the raised member 40 is moving from the temporary mounting position to the main mounting position, after the tips of the pair of fitting protrusions 60 rush into the pair of fitting holes 29, the inclined surface 61A of the locking protrusions 61 Abuts on the inner edge of the upper end flange 17. Then, from there until the raised member 40 reaches the main mounting position, the inclined surface 61A of the locking protrusion 61 slides into contact with the inner edge of the upper end flange 17, and the inner hanging piece 44 and the raised bottom wall 53 are brought into contact with each other. When the locking protrusion 61 is elastically deformed and rides on the upper end flange 17 and the raising member 40 reaches the main mounting position, the inner hanging piece 44 and the raised bottom wall 53 elastically return to the locking protrusion 61. It fits into the locking hole 27 of the box-shaped container 11. Then, the locking surface 61B of the locking protrusion 61 and the inner surface of the locking hole 27 face each other, which restricts the sliding of the raised member 40 in the reverse direction.

In the present embodiment, the outer hanging piece 45 and the locking protrusion 48, the inner hanging piece 44, the raised bottom wall 53, and the locking protrusion 61 are "elastic locking portions" within the scope of the claims.

Further, the inner hanging piece 43 and the outer hanging piece 45 of the first straight portion 41 are slidably engaged with the short side wall 12 of the box-shaped container 11 in the longitudinal direction of the first straight portion 41. Parts 46 and 47 are provided. Then, as shown in FIG. 8A, the raising member 40 has a first straight portion at a temporary mounting position where the inner hanging piece 44 of the second straight portion 42 is separated inward from the inner side surface of the box-shaped container 11. The short side wall 12 of the box-shaped container 11 is received between the inner hanging piece 43 and the outer hanging piece 45 of 41, and as shown in FIG. 8 (B), the inner hanging piece 44 of the second straight portion 42 is a box-shaped container. The attachment to the box-shaped container 11 is completed by sliding to the main mounting position overlapping the inner side surface of 11. As described above, in the raising member 40 of the present embodiment, the inner hanging piece 43 of the first straight line portion 41 and the inner hanging piece 44 of the second straight line portion 42 are orthogonal to each other with the corner portion 11C of the box-shaped container 11 interposed therebetween. It overlaps each of the pair of inner surfaces. As a result, it is possible to suppress the occurrence of a problem that the load in the box-shaped container 11 comes into contact with the raising member 40 and the raising member 40 unintentionally comes off from the box-shaped container 11, and the raising member with respect to the box-shaped container 11 is prevented from occurring. The mounting of 40 is stable.

Further, in the configuration of the present embodiment, when the raising member 40 is arranged at the main mounting position, the locking protrusions 48 and 61 of the raising member 40 are locked to the box-shaped container 11, so that the raising member 40 is locked. The slide of the 40 in the direction away from the box-shaped container 11 is prevented. Moreover, as shown in FIG. 9, both the outer surface of the first straight portion 41 of the raised member 40 and the outer surface of the second straight portion 42 are inside the tip surface of the upper end flange 17 of the box-shaped container 11. Since it is located, it becomes difficult for foreign matter to get caught in the raised member 40, and this also suppresses the occurrence of a problem that the raised member 40 is unintentionally detached.

Further, in the present embodiment, the lower end portion of the outer hanging piece 45 in the first straight line portion 41 of the raising member 40 is located above the lower end portion of the inner hanging piece 43. As a result, as shown in FIG. 5, the raising member 40 is placed in an inclined posture in which the outer edge side of the first straight line portion 41 on which the outer hanging piece 45 is arranged is lowered, and the sliding engaging protrusion of the outer hanging piece 45. The portion 47 can be easily engaged with the outer surface of the box-shaped container 11 (specifically, the lower surface of the tip portion of the upper end flange 17). Then, as shown in FIG. 6, when the raising member 40 is placed in the horizontal posture, the slide engaging protrusion 46 of the inner hanging piece 43 is formed on the inner surface of the box-shaped container 11 (specifically, the guide of the box-shaped container 11). Easily engages with the recess 28). As described above, according to the configuration of the present embodiment, the raising member 40 can be easily assembled to the box-shaped container 11.

Further, when the raising member 40 is arranged at the main mounting position, as shown in FIG. 7B, a pair of fitting protrusions 60 protruding from the inner hanging piece 43 of the second straight portion 42 becomes a box. By fitting into the pair of fitting holes 29 of the shape container 11, the upward displacement of the raising member 40 can be suppressed. Further, when the containers with the raising members 10 are stacked, the lower surface protrusion 15 (see FIG. 2) on the upper side is fitted inside the four raising members 40 of the container 10 with the raising member on the lower side. Lateral slippage between the containers with raising members 10 can be prevented. Further, as shown in FIG. 7B, the reinforcing ribs 56A, 56B, 56C of the raising member 40 are arranged directly above the corners of the box-shaped container 11 and the vertical ribs 18A, 18B, 18C in the vicinity thereof, respectively. Therefore, the deformation of the box-shaped container 11 due to the load of the box-shaped container 11 on the upper stage side is suppressed, and the stacking posture is stabilized.

The container 10 with a raising member can also be used alone as the box-shaped container 11. In this case, when the box-shaped containers 11 are stacked one above the other, the upper surface opening 11K (see FIG. 1) of the lower box-shaped container 11 is fitted with the lower surface protrusion 15 (see FIG. 2) to fit the box. Lateral slippage between the shaped containers 11 can be prevented.
