  FIG. 1 shows an embodiment of a metal packing container 11 of the present invention.

  The metal packing container 11 of the present embodiment includes a rectangular lower pallet 12 on which the stored items are placed, a plurality of (four in the present embodiment) side panels 13 that surround the side surfaces of the stored items, and a storage And an upper panel 14 that closes the top of the object. These lower pallet 12, side panel 13 and upper panel 14 are steel plate face plates 15 as shown in FIGS. 3 and 4, each having a plurality (n + 1 (n is a natural number), three in the figure). ) Convex portions 16 and a plurality (n, two in the figure) of concave portions 17 are formed so as to have a cross-sectional shape alternately arranged via side surface portions 16a, and the ends of the convex portions 16 at both ends in the width direction are formed. The portion 18 is formed by using a plurality of steel plate face plates bent in an L shape on the inside.

  Next, each component will be further described.

  The lower pallet 12 includes a plurality of upper members 19 formed by steel plate face plates 15 arranged in parallel (two in this embodiment, two at each end), and a lower surface of the upper member 19. The plurality of support members 20 are arranged in parallel to each other and fixed to support the upper member 19.

  Since the face plate 15 forming each component of the present invention is integrally formed with the cross-sectional shape shown in FIG. 3 (in FIG. 4A, the cross-sectional shapes of the face plate 15 and the face plate 15 are omitted in the figure. Even if it is manufactured using a relatively thin steel plate, sufficient rigidity can be obtained as will be described later.

  The support member 20 is formed by bending the face plate 15 at four locations in the longitudinal direction into a columnar shape (see FIG. 4A). As shown in FIG. 4 (b), the bending process may be performed by crushing or bending the concave portion 17, the side surface portion 16a, and the end portion 18 that become side portions when bending, and the bottom portion. The convex portion 16 to be formed may be bent along the fold line A, and may be bent without providing a crushing portion. Since the face plate 15 having the above-described cross-sectional structure is bent in this manner, the convex portion 16 and the concave portion 17 are plural pairs on two opposing surfaces of the obtained support member 20. They are formed in parallel.

  Moreover, as shown in FIG. 3, it is preferable that the edge part 18 of the face plate 15 is bent by the L shape below. In this way, it is possible to prevent the cut end face of the face plate 15 from being exposed and to avoid damaging the operator's body and clothes.

Reinforcing members 21 are fitted into at least one pair of the convex portions 16 (one pair at both ends of the support member 20 and two pairs at the intermediate portion in FIGS. 1 and 2) and combined to reinforce. As shown in FIG. 5 (a) or (b), the reinforcing member 21 is formed by bending a steel plate into a substantially U-shaped cross section (21a, 21b, 21c), or as shown in FIG. The both end portions bent in a letter shape are further bent inward (21d), or as shown in FIG. 5 (d), are bent so as to have the same cross section as the face plate 15 (21e). . In each reinforcing member 21, when the widths of the bent portions (21a, 21b, 21c), which are narrow width portions, are fitted to the widths of the convex portions 16 and the convex portions 16 at both ends, the end portions 18 are further provided. As shown in FIG. 6 (a) or (b), the support member 20 and the reinforcing member 21 are fitted and combined with no gap therebetween. As shown in FIGS. 6 (a) and 6 (b), the reinforcing member 21 is fitted to and combined with two pairs of convex portions 16 at both ends at both ends and an intermediate portion of the support member 20, thereby reducing the load. It is possible to make the support member 20 difficult to be deformed even if it is loaded.

  In this way, a plurality of support members 20 (three in the present embodiment) in which the reinforcing members 21 are combined are arranged in parallel so as to straddle the support members 20 as shown in FIGS. 1 and 2. The four face plates 15 constituting the upper member 19 are placed vertically, and the contact points of the support member 20 and the face plate 15 are joined together by a known joining method such as spot welding, caulking, or rivet to be integrated. The face plate 15 may be installed in a packed manner so as not to leave a gap in the entire longitudinal direction of the support member 20. Further, the corner abutting members 29 shown in FIGS. 8A to 8C are aligned with the four corners of the lower pallet 12 and fixed by welding as shown in FIGS. The corner abutting member 29 is formed by bending a thin steel plate.
