Then, the lower end flange 13 is buried in the ground, and the cement 95 and the soils 88 and 89 enter between the corner reinforcing walls 21 and 21 and between the plurality of longitudinal ribs 15L and the plurality of transverse ribs 15M. The lower end portion of the container 10 is stably fixed in the ground, and the shift and wobble of the home delivery box 10 is suppressed.

  Further, the load applied to the lid 30 is not only the contact between the flange 33A of the outer edge thereof and the bottom surface 20A of the step portion 20 of the box main body 11, but a plurality of loads arranged annularly on the outer edge of the lower surface of the lid 30. Also, the load is distributed and the deformation of the lid 30 is suppressed because the outer rib 34 is received by the abutment between the outer peripheral rib 34 and the inner annular wall 17 and the upright facing wall 19 of the box body 11. Moreover, the cylindrical corner reinforcing wall 21 plays a role as a support by being sandwiched between the extended wall 16 at the upper end position and the lower end flange 13 at the lower end. These increase the strength against the load from above. Here, when the cylindrical corner reinforcing wall 21 becomes long, there is a concern that the in-cylinder molding portion of the mold to be formed therein becomes long and the resin is deformed by the resin pressure in the injection molding machine. In the delivery box 10, since the inside of the corner reinforcing wall 21 is gradually narrowed toward the middle portion in the vertical direction, the in-cylinder molded portion is divided into two in the longitudinal direction to withstand the resin pressure. You can do it.

Furthermore, the corner reinforcing wall 21 may be extended upward from the extension wall 16 to abut on the lid 30. In that case, holes for flowing water from the water receiving groove 24 to the drain holes 22 may be formed on the side surface of the corner reinforcing wall 21.

(2) Further, the corner reinforcing wall 21 may not be cylindrical, and may be rib-shaped, for example.

(3) Further, in the delivery box 10 of the above-described embodiment, the standing facing wall 19 is divided into four sides, but the drainage holes 22 are made slightly smaller and the standing facing walls 19 and 19 on both sides adjacent to each other are annular It may be connected similarly to the wall 17.

(4) In the delivery box 10 of the above embodiment, the bottom of the box main body 11 is provided with a drain hole and a plug is provided, and when water enters the delivery box 10, the plug can be removed for draining. You may

(5) In the delivery box 10 of the above embodiment, the gap between the inner annular wall 17 and the rising facing wall 19 may be communicated with the drainage hole 22 or the gap may be filled with a sealing material.

(6) In the delivery box 10 of the above embodiment, the inside of the corner reinforcing wall 21 is the drainage hole 22. However, in order to drain the water from the water receiving groove 24 to the outside, for example, the corner reinforcing wall 21 is provided. Alternatively, the drainage holes 22 may be provided so as to penetrate the extended wall 16 up and down or to penetrate the outer fitting wall 18 from the side.
