The bottom contact piece 1c is connected to the tip of one inner dam plate 3b, and the middle bottom plate 1b is connected to the tip of the other inner dam plate 3b. The short side on both sides of the middle bottom plate 1b is located on the inner side than the lower bottom plate 1a.

  The ruled lines at the boundary between one inner dam plate 3b and the bottom abutment piece 1c and the boundary between the other inner dam plate 3b and the middle bottom plate 1b enable valley folding in which the surface side of the cardboard is depressed. It is a lead ruled alternately. In the other inner weir plate 3b, a lead ruled bending wire 3d parallel to the boundary is provided near the boundary with the middle bottom plate 1b in order to allow free bending and stretching.

  Two engaging recesses 42 are formed on each side by square cuts from the end edges at portions facing the short sides on both sides of the lower bottom plate 1a.

  The bottom sheet 12 is made of ordinary double-sided cardboard, and the bottom wall reinforcing plates 13 and 14 are made of double-layered double-sided cardboard. The bottom cover plate 12 and the bottom wall reinforcement plates 13 and 14 are rectangular in shape and the dimensions in the short side direction are sequentially reduced, and one long side of the bottom cover plate 12 and the bottom wall reinforcement plate 13 has an arcuate edge for finger hooking. An incision to be made is formed in the center portion.

  The side wall member 21 includes an outer plate 2a and an inner plate 2b that are connected to each other via a frame portion 2c, a joining piece 1d that is connected to the tip of the inner plate 2b, and frame portions 2d that are provided on both sides of the outer plate 2a. Thus, the sticking piece 2e is continuously provided, and the outer connecting piece 31 and the inner connecting piece 32 are extended from the lower portions on both sides when the outer plate 2a and the inner plate 2b are assembled.

  Two ruled lines at the boundary between the inner plate 2b and the joining piece 1d are put in parallel, and are used as lead rules to enable valley folding. Both side portions of the inner plate 2b are cut out in accordance with the shape of the sticking piece 2e, and the both end portions of the joining piece 1d are cut out at right angles.

  The boundary between the sticking piece 2e and the outer connection piece 31 is cut off, and the frame portion 2d is cut from the boundary between the sticking piece 2e and the outer connection piece 31. Bending in an arbitrary direction with the outer connection piece 31 and the inner connection piece 32 bonded to the ruled line at the boundary between the outer connection piece 31 and the frame portion 2d and the ruled line at the boundary between the inner connection piece 32 and the inner plate 2b In order to make this possible, a cut is made in each intermediate part.

  The outer connecting piece 31 and the inner connecting piece 32 are respectively provided with the oblique fold lines 33 of the ruled lines, and the oblique fold lines 33 are arranged so that the lower side during assembly approaches the outer plate 2a and the inner plate 2b, respectively. Inclined, and two oblique lines 33 of the outer connecting piece 31 are parallel to each other.

  From the frame portion 2c to the inner plate 2b, two punched holes 41a are formed for projecting engagement convex portions 41 of the side wall reinforcing member 22 to be described later, and the outer plate 2a is slightly extended from the frame portion 2c. An oblong handle hole 2f is formed at a distant position.

  Further, the side wall reinforcing member 22 is composed of a double-layered cardboard having a two-layer structure, and in order to enable folding, a pair of side wall reinforcing plates 22a are connected via a half cut line that is cut halfway in the thickness direction. Has been.

  Two engaging convex portions 41 are provided at the tips of the pair of side wall reinforcing plates 22a, respectively, and two engaging concave portions 42 are formed by cutting out the connecting portions between the side wall reinforcing plates 22a. . Oval handle holes 2f are formed near the ends of the pair of side wall reinforcing plates 22a.

  In addition, the main body 11, the side wall member 21, and the side wall reinforcing member 22 are engraved with marks that serve as a reference for the pasting position at the time of assembly, and the bottom cover plate 12, the bottom wall reinforcing plates 13, 14 and the side wall reinforcing member 22 A V-shaped notch is formed to match the above-mentioned mark.

  In order to assemble the stacking tray as shown in FIG. 1 from the blank of each member, the pair of side wall reinforcing plates 22a of the side wall reinforcing member 22 are folded and bonded together, and the side wall reinforcing member is attached to the inner surface of the outer side plate 2a of the side wall member 21. The side wall reinforcing member 22 is affixed to the inner surface of the outer plate 2a in a state in which the steps 22 are stacked so that the steps are vertically oriented, and the engaging protrusions 41 are protruded from the hole 41a.

  Next, the frame portions 2c and 2d are bent so as to be along the upper end and the side end of the side wall reinforcing member 22, respectively, and the inner side plate 2b is attached to the side wall reinforcing member 22 so as to be overlapped, and the adhesive piece 2e is bent. Affixed to the side wall reinforcing member 22. Thereby, the side wall member 21 and the side wall reinforcement member 22 are integrated, and the side wall 2 of a quadruple structure is formed.

  Further, the outer connecting piece 31 extending from the outer plate 2 a and the inner connecting piece 32 extending from the inner plate 2 b are bonded together at the distal end side without being bonded together at the proximal end side with respect to the oblique line 33.

  Then, as shown in FIG. 2, with respect to the main body 11, the side wall 2 is directed in the direction in which the outer plate 2a is the outer surface and the inner plate 2b is the inner surface, and the joining piece 1d is bent inward, and the short side of the lower bottom plate 1a Affix to the part that faces. Further, the outer connecting piece 31 is attached to the inner surface of the outer dam plate 3a at the distal end side without being attached at the proximal end side with respect to the oblique line 33.

  In addition, the bottom wall reinforcing plates 14 and 13 and the bottom laying plate 12 are sequentially stacked and bonded to a surface that faces upward when the middle bottom plate 1b of the main body 11 is assembled so that the steps intersect with the middle bottom plate 1b.

  After that, the outer dam plate 3a is erected, the frame portion 3c is bent inward, the inner dam plate 3b is sequentially bent downward, and the outer connecting piece 31 and the inner connecting piece 32 extend without being bent along the oblique line 33. Thus, when the outer connecting piece 31 and the inner connecting piece 32 are sandwiched between the outer dam plate 3a and the inner dam plate 3b, the dam wall 3 is formed, and the standing side walls 2 are maintained in an upright state.

  Then, the bottom abutting piece 1c is bent from one inner dam plate 3b so as to overlap the lower bottom plate 1a, and the tip of the bottom abutting piece 1c is engaged with the notch edge of the end portion of the joining piece 1d. While the weir plate 3b is bent and stretched along the bending line 3d, the bottom plate 12, the bottom wall reinforcing plates 13 and 14, and the middle bottom plate 1b are swung downward and overlapped on the upper surface of the lower bottom plate 1a. As a result, the stacking tray is in the assembled state as shown in FIG. 1, and the bottom wall 1 having a quintuple structure is formed.

  In the stacking tray assembled in this manner, the engaging convex portion 41 protrudes from the upper end of the side wall 2, and the engaging concave portion 42 of the lower bottom plate 1 a and the side wall reinforcing plate 22 a communicates with each other. 42 is opened, and the handle holes 2f of the outer side plate 2a and the side wall reinforcing plate 22a communicate with each other at a position slightly spaced downward from the upper end of the side wall 2.

  Further, as shown in FIG. 2, the stacking tray jumps up the bottom plate 12, the bottom wall reinforcing plates 13 and 14, and the middle bottom plate 1b, and connects the inner connection piece 31 and the inner connection piece 31 by the outer dam plate 3a and the inner dam plate 3b. When the clamping of the piece 32 is released, as shown in FIG. 3, the folding of the outer connecting piece 31 and the inner connecting piece 32 along the oblique fold line 33 causes the opposing side wall 2 to fall inward so as to overlap the bottom wall 1. .

  Then, as shown in FIG. 4, the frame portion 3c of the dam wall 3 and the inner dam plate 3b are bent so as to be wound, and the bottom laying plate 12, the bottom wall reinforcing plates 13 and 14, and the midsole plate 1b are stacked above the side wall 2. And it can be set as a compact folded state.

  As described above, in this stacking tray, the side wall 2 and the outer weir plate 3 a are connected by the outer connecting piece 31 and the inner connecting piece 32, and the oblique folding line 33 is put in the outer connecting piece 31 and the inner connecting piece 32. Therefore, the side walls 2 on both sides can be folded inward and folded compactly, and when the side walls 2 are raised from the folded state, the outer dam plate 3a rises in conjunction with each other, and therefore, between the outer dam plate 3a and the inner dam plate 3b. The outer connecting piece 31 and the inner connecting piece 32 can be easily assembled by simply sandwiching them.

  At this time, the outer connecting piece 31 and the inner connecting piece 32 respectively extending from the outer plate 2a and the inner plate 2b are bonded together at the distal end side without being bonded together at the proximal end side relative to the oblique fold line 33, so that the side wall 2 is Even if it is considerably thick, bending along the oblique line 33 between the outer connecting piece 31 and the inner connecting piece 32 is allowed by contact and separation of the unattached portion, and the outer connecting piece 31 and the inner connecting piece 32 are prevented from being broken. In addition, the fall and standing of the side wall 2 accompanying folding and assembly are not hindered.

  In the assembled state, the standing state of the quadrilateral side wall 2 is maintained by the blocking wall 3, so that the stacking on the upper side is placed on the top of the side wall 2 of the stacking tray on the lower side as shown in FIG. By placing the tray and fitting the engaging convex part 41 of the lower stacking tray into the engaging concave part 42 of the upper stacking tray to prevent misloading, a heavy product in a stable stacking state Can be displayed.

  Moreover, since the outer connecting piece 31 and the inner connecting piece 32 have sufficient strength even if the height dimension is small with respect to the side wall 2, the height of the opposing dam wall 3 can be lowered. Thus, the product placed on the bottom wall 1 can be displayed so that it can be seen well from the front and rear.

  In the above embodiment, the main body 11 and the left and right side wall members 21 are separated from each other. However, in a relatively small stacking tray, a portion corresponding to the main body 11 and a portion corresponding to the left and right side wall members 21 are provided. Alternatively, it may be formed from a single blank.

  In addition, since it is assumed that very heavy products are placed, the bottom wall reinforcing plates 13 and 14 and the side wall reinforcing member 22 are exemplified by using double-sided corrugated cardboard as a material. If they are not heavy, they may be made of ordinary double-sided cardboard, and the number of the sheets may be increased or decreased according to the weight of the product. Moreover, when the weight of goods is light, all or some of these may be omitted.
