The decorative sheet 42 is provided up to the front plate 411 and the folded portion 412 of the metal plate 41, and is folded toward the rear side together with the folded portion 412.

[0017] The decorative sheet 42 is a wrapping sheet, and has an adhesive portion on the back surface. Examples of the adhesive portion include double-sided tape, adhesive, and pressure-sensitive adhesive. In this embodiment, for example, the adhesive portion is formed by applying an adhesive to the back surface of the base material of the decorative sheet 42, and then heating and drying the adhesive. The decorative sheet 42 is then attached to the surface of the metal plate 41 made of stainless steel by the adhesive portion. The surface of the decorative sheet 42 may be provided with, for example, a wood grain pattern, design, or pattern, or may be provided with a single color.

[0018] 2 and 3, the rear resin cover part 43 is formed to have approximately the same size as the front plate 411 of the metal plate 41. The rear resin cover part 43 is attached to the rear surface of the metal plate 41 so as to cover the rear surface of the front plate 411 of the metal plate 41.

[0019] The rear resin cover part 43 is attached to the rear surface of the metal plate 41, and as shown in Fig. 3 to Fig. 5, the edge parts 42a, 42b, 42c of the decorative sheet 42 are sandwiched and fixed between the metal plate 41 and the rear resin cover part 43. As shown in Fig. 3, the rear resin cover part 43 has a resin cover part main body 431, three upper end hook parts 432 formed on the upper end part of the surface of the resin cover part main body 431 facing the metal plate 41, and two pairs of shaft member attachment parts 433 formed on the upper end part of the surface of the resin cover part main body 431 facing the metal plate 41.

[0020] The resin cover part main body 431 is disposed on the back surface of the front plate 411 of the metal plate 41. As shown in Figs. 4 and 5, an edge portion 431a of the resin cover part main body 431 sandwiches the edge portions 42a, 42b, and 42c of the decorative sheet 42 between the edge portion 431a and a folded portion 412 formed on the periphery of the metal plate 41. As a result, the edge portions 42a, 42b, and 42c of the decorative sheet are sandwiched and disposed between the folded portion 412 formed on the periphery of the metal plate 41 and the edge portion 431a of the resin cover part main body 431 of the rear resin cover part 43.

[0021] 3, the three upper end hooking parts 432 are arranged at a distance in the left-right direction on the upper end of the surface of the resin cover part main body 431 facing the metal plate 41. The hooking parts 432 are formed in a U-shape that opens upward. The hooking parts 432 are hooked onto the bent plate part 413b of the upper end bent edge part 413 of the metal plate 41.

[0022] When attaching the rear resin cover part 43 to the rear surface of the metal plate 41, the rear resin cover part 43 is placed on the rear surface of the metal plate 41 with the hook part 432 of the rear resin cover part 43 at the upper end part thereof hooked onto the bent plate part 413b of the upper end bent edge part 413 of the metal plate 41. In this state, the rear resin cover part 43 is fixed to the rear surface of the metal plate 41 with the screw 45 at the lower end part of the rear resin cover part 43, as shown in FIG.

[0023] In a state where the rear resin cover part 43 is attached to the rear surface of the metal plate 41, at the upper end of the metal plate 41, as shown in Fig. 4, an upper end side edge part 42a of the decorative sheet 42 is sandwiched between the bent plate part 413b of the upper end folded edge part 413 of the metal plate 41 and the upper end edge part 431a of the rear resin cover part 43. At the lower end of the metal plate 41, a lower end side edge part 42b of the decorative sheet 42 is sandwiched between the bent plate part 414b of the lower end folded edge part 414 and the lower end edge part 431a of the rear resin cover part 43. At both left and right ends of the metal plate 41, as shown in Fig. 5, a left and right end side edge part 42c of the decorative sheet 42 is sandwiched between the rear side end part of the left and right end folded edge part 415 and the left and right end edge part 431a of the rear resin cover part 43.

[0024] As shown in Fig. 3, the pair of shaft member attachment parts 433 are arranged at a distance in the left-right direction on the upper end of the surface of the resin cover part main body 431 facing the metal plate 41. A shaft member 44 (functional part) that serves as a rotation axis J (see Fig. 1) when opening and closing the front door 4 is attached to the shaft member attachment parts 433. The shaft member 44 is configured as a functional part that realizes the function of a rotation axis for opening and closing the front door 4. Since the rear resin cover part 43 is formed of a resin material, it is easy to attach a functional part such as the shaft member 44 that serves as a rotation axis for opening and closing the front door 4.

[0025] In the front door 4 configured as described above, the metal plate 41, the rear resin cover part 43 and the decorative sheet 42 are made of materials with different expansion coefficients. However, since the rear resin cover part 43 is attached to the rear side of the metal plate 41 with the edges 42a, 42b, 42c of the decorative sheet 42 sandwiched and fixed between the metal plate 41 and the rear resin cover part 43, peeling of the edges 42a, 42b, 42c of the decorative sheet 42 can be prevented.

[0026] Next, a method for wrapping the front door 4 (door) of the mailbox 1 (storage box) will be described. First, a decorative sheet 42 is attached to the surface of a metal plate 41 that is placed on the front side of the front door 1 of the mailbox 1, and the edge of the decorative sheet 42 is folded and placed on the back side of the metal plate 41 (surface material placement process).

[0027] Then, in a state where the edge portions 42a, 42b, 42c of the decorative sheet 42 are sandwiched and fixed between the metal plate 41 and the rear resin cover portion 43, the rear resin cover portion 43 is attached to the rear surface of the metal plate 41 (resin portion attachment process). As a result, since the edge portions of the decorative sheet 42 are sandwiched between the metal plate 41 and the rear resin cover portion 43, the decorative sheet 42 can be provided on the surface of the metal plate 41 of the front door 4 in a state where the edge portions 42a, 42b, 42c of the decorative sheet 42 are prevented from peeling off.

[0028] The wrapping structure for the front door 4 of the mailbox 1 of this embodiment described above provides the following advantages.

[0029] In this embodiment, the wrapping structure of the front door 4 of the mailbox 1 includes a metal plate 41 arranged on the front side of the front door 4 of the mailbox 1, a decorative sheet 42 provided on the surface of the metal plate 41 and having edge portions 42a, 42b, 42c folded toward the rear side of the metal plate 41, and a rear resin cover portion 43 attached to the rear side of the metal plate 41 and sandwiching and fixing edge portions 42a, 42b, 42c of the decorative sheet 42 between the metal plate 41 and the rear resin cover portion 43. As a result, the edge portions of the decorative sheet 42 are sandwiched between the metal plate 41 and the rear resin cover portion 43, so that the decorative sheet 42 can be provided on the surface of the metal plate 41 of the front door 4 while preventing peeling of the edge portions 42a, 42b, 42c of the decorative sheet 42.

[0030] In this embodiment, the metal plate 41 has a bent portion 412 provided on the periphery and bent toward the rear side, and the edge portions 42a, 42b, and 42c of the decorative sheet 42 are sandwiched and fixed between the bent portion 412 and the edge portion 431a of the rear resin cover portion 43. This allows the edge portions 42a, 42b, and 42c of the decorative sheet 42 to be stably sandwiched between the bent portion 412 of the metal plate 41 and the edge portion 431a of the rear resin cover portion 43.

[0031] In this embodiment, an axis member 44 that serves as a rotation axis J when opening and closing the front door 4 is attached to the rear resin cover part 43. Since the rear resin cover part 43 is made of a resin material, it is easy to attach a functional part such as the axis member 44 that serves as a rotation axis for opening and closing the front door 4.

[0032] The wrapping method for the front door 4 of the mailbox 1 of this embodiment includes a surface material arranging step of attaching a decorative sheet 42 to the surface of a metal plate 41 arranged on the front side of the front door 1 of the mailbox 1 and folding and arranging an edge portion of the decorative sheet 42 to the back side of the metal plate 41, and a resin part mounting step of mounting the back resin cover part 43 to the back side of the metal plate 41 in a state in which the edge portions 42a, 42b, 42c of the decorative sheet 42 are sandwiched and fixed between the metal plate 41 and the back resin cover part 43 after the surface material arranging step. As a result, since the edge portion of the decorative sheet 42 is sandwiched between the metal plate 41 and the back resin cover part 43, the decorative sheet 42 can be provided on the surface of the metal plate 41 of the front door 4 in a state in which the edge portions 42a, 42b, 42c of the decorative sheet 42 are prevented from peeling off.
