Next, for example, the surface layer of the ground is removed to a position lower than the expansion wall 16 of the luggage storage box 10 to perform leveling. Next, the reinforcing bars 97 are laid on top of each other in a grid pattern. Then, the cement layer 98 is formed so that the reinforcing bar 97 is embedded, the upper surface of the cement layer 98 is leveled at a position slightly lower than the upper surface of the luggage storage box 10, and then the tile 99 is spread on the cement layer 98. As described above, the luggage storage box 10 is embedded in the ground such as the front door of the house as shown in FIG. 12 (A).

Next, the operation and effect of the luggage storage box 10 of the present embodiment will be described. The luggage storage box 10 is used, for example, to store parcels in the absence of a resident. For that purpose, the resident and the courier company keep the wireless remote controller of the locking unit 43 of the luggage storage box 10 in their possession. Then, when the resident is absent, the courier unlocks the luggage storage box 10, opens the lid 30, stores the luggage in the luggage storage box 10, and then locks the luggage. Make a note of the delivery. The resident returns home, unlocks the luggage storage box 10 and opens the lid 30 based on the memo, takes out the delivery, closes the lid 30 and locks it. In this way, the delivery of the delivery to the home away from home can be smoothly performed, the trouble of redelivery can be saved, and the labor shortage of the delivery company can be taken as a countermeasure. In order to make it easy to take out the delivery from the luggage storage box 10, it is preferable to store the delivery in a bag with a handle or an inner box and store it in the luggage storage box 10.

By the way, since the luggage storage box 10 is embedded in the front door of the house or the like, the appearance is important. On the other hand, in the luggage storage box 10 of the present embodiment, since the lid 30 is fitted inside the box body 11, as shown in FIG. 12, the luggage storage box can be closed or opened. The circumference of the upper end portion of the 10 can be simplified to match the tile 99 and the like, and the appearance can be made beautiful. On the other hand, since the lid 30 is fitted inside the box body 11, there is a concern that water may enter the gap between the lid 30 and the box body 11 from above.

However, as shown in FIG. 5, the lower surface of the flange portion 33A of the lid body 30 comes into surface contact with the bottom surface 20A of the step portion 20 provided at the opening edge of the box body 11, so that a large amount of rainwater comes into contact with the lid body 30 and the box. It is prevented from flowing into the luggage storage box 10 through the gap with the main body 11.

Further, at a position near the upper end of the inner surface of the box body 11, an annular step surface 16A facing the entire outer edge portion of the lid 30 from below is provided, and an inner annular wall 17 stands up from the entire annular step surface 16A. Therefore, even if water enters through the gap between the outer fitting wall 18 and the lid 30, it is blocked by the inner annular wall 17 and receives water between the outer fitting wall 18 and the inner annular wall 17. Accepted by groove 24. As a result, water intrusion into the inside of the box body 11 in which the luggage is housed is suppressed. Further, since the water in the water receiving groove 24 is discharged to the outside through the drain hole 22 shown in FIG. 4, it is possible to prevent the water from flowing into the inside of the box main body 11 from the water receiving groove 24. Since the upper end of the drain hole 22 is closed by the corner tray 23 (see FIG. 6), it is possible to prevent, for example, a house key or the like from falling into the drain hole 22. Further, since the heat insulating sheet 40 is provided on the lower surface of the lid 30, it is possible to suppress the influence of the outside air temperature on the inside of the luggage storage box 10.

Further, the load applied to the lid body 30 from above is not only the contact between the flange portion 33A of the outer edge of the lid body 30 and the bottom surface 20A of the stepped portion 20 of the box body 11, but also an annular shape on the outer edge portion of the lower surface of the lid body 30. Since it is also received by the contact between the plurality of outer edge ribs 34 arranged in the box body 11 and the inner annular wall 17 and the standing facing wall 19 of the box body 11, the load related to the lid body 30 is distributed and the deformation of the lid body 30 is suppressed. Be done. As a result, the contact between the flange 33A of the lid 30 and the bottom surface 20A of the box body 11 is stable, and the waterproof function inside the luggage storage box 10 is also stable.
