That is, the bottom portion 30 includes a pair of outer flaps 31, 31 connected to the lower portions of the side walls 11, 11 and a pair of inner flaps 32, 32 respectively connected to the lower portions of the both end walls 12, 12. I have. The outer flap 31 and the inner flap 32 have a rectangular shape and are separated from each other. A horizontal rule 3e is formed along the boundary line between the outer flap 31 and the side wall 11 adjacent in the vertical direction. A horizontal rule 3 f is formed along the boundary line between the inner flap 32 and the end wall 12. The horizontal rules 3e and 3f are both ruled lines extending in the horizontal direction (width direction) and are formed in the same straight line.

  During box making, the outer flap 31 extends inward from the lower end of the side wall 11, and the inner flap 32 extends inward from the lower end of the end wall 12. The inner flap 32 is folded inside the outer flap 31 (see FIG. 2).

  As shown in FIG. 2, the lid / outer flap 21 and the lid / inner flap 22 during transportation are not bent and have a flat plate shape. The lid / outer flap 21 extends inward from the upper end of the side wall 11, and the lid / inner flap 22 extends inward from the upper end of the end wall 12. The lid / inner flap 22 is folded inside the lid / outer flap 21.

  The closed bottom portion 30 and the lid portion 20 can be fixed by any means, but it is most desirable to fix the bottom portion 30 and the lid portion 20 using an adhesive tape because the work is easy. In addition, it is preferable to use what can be removed for the adhesive tape which fixes the cover part 20. FIG.

  When stacking the stacking tray box 1, as shown in FIG. 6, the lid / outer flap 21 and the lid / inner flap 22 are bent. The upper end support plate portion 23 of the lid / outer flap 21 extends in the inner horizontal direction from the upper end of the side wall 11, and the inner side wall plate portion 24 extends downward from the tip of the upper end support plate portion 23. The upper end support plate portion 26 of the lid combined inner flap 22 extends from the upper end of the end wall 12 toward the inner horizontal direction, and the inner wall plate portion 27 extends downward from the tip of the upper end support plate portion 26. . The tip corner 22b of the lid / inner flap 22 enters the space formed by chamfering the lid / outer flap 21, and the tip corner 22b is locked to the chamfer 28. Thus, the side edge 21a of the lid / outer flap 21 and the side edge 22a of the lid / inner flap 22 are fixed to each other.

  Below, the formation procedure of the frame-shaped support surface 25 utilized at the time of stacking is demonstrated, referring FIGS. 3-5. First, as shown in FIG. 3, the lid and outer flaps 21 and 21 and the lid and inner flaps 22 and 22 are opened to open the upper opening / closing portion. The lid / outer flap 21 and the lid / inner flap 22 are once opened to a position extending upward. At this time, the lid / outer flap 21 and the lid / inner flap 22 do not interfere with each other.

  After that, as shown in FIG. 4, the horizontal ruled line 3a is used as a fold, the lid / external flap 21 is tilted in the horizontal direction with respect to the side wall 11, and the first boundary line (horizontal ruled line 3b) is used as a fold. The combined outer flap 21 is bent. When the lid / outer flap 21 is bent, the inner side wall plate portion 24 extends downward from the tip (inner end) of the upper end support plate portion 23, so that a double wall structure is formed inside the side wall 11. The The inner wall plate part 24 is bent so that the angle formed between the upper end support plate part 23 and the inner wall plate part 24 is an acute angle so that the lower end of the inner wall plate part abuts on the inner surface of the side wall 11. The inner dimension L4 between the upper end support plate portions 23, 23 formed here is larger than the width dimension L3 of the front end of the lid / inner flap 22.

  Next, as shown in FIG. 5, the lid combined inner flap 22 is bent. First, as shown in (a) of FIG. 5, the inner ruler 22 for both the lid and the inner wall 22 is tilted horizontally with respect to the end wall 12 with the horizontal ruled line 3 c as a fold. The tip of the side edge portion 22 a of the inner cover flap 22 (portion shown by dot hatching in FIG. 5A) is positioned on the upper end support plate 23 of the outer lid cover 21.

  After that, as shown in FIG. 5B, the lid / inner flap 22 is bent with the second boundary line (horizontal rule 3d) as a fold. At this time, the inner wall plate portion 27 is pushed between the opposed inner wall plate portions 24, 24, and the tip portion is bent. That is, when the inner side wall plate portion 27 is folded while the side edge portion 22a is deformed, the side wall portion 22a extends downward. The end of the second boundary line (vertex P of the notch 29) is located above the first boundary line in plan view in the box making state, and above the top end support plate part 23 of the lid-use outer flap 21. The lid combined inner flap 22 is bent. Therefore, the lid combined inner flap 22 can be accurately bent along the second boundary line, and the appearance can be made beautiful.

As shown in FIG. 5C, the inner wall plate portion 27 is pushed in until the lower end of the inner wall plate portion 27 comes into contact with the inner surface of the side wall 11. Then, the tip corner 22b enters the space formed by chamfering and the bending of the tip is eliminated. And the front-end | tip corner | angular part 22b is latched by the chamfering part 28, and the side edge part 22a of the lid | cover outer flap 21 and the side edge part 22a of the lid | cover inner flap 22 are mutually fixed. At this time, since both the inner side wall plate portions 24 and 27 are repelled to return to the inner side, the tip corner portion 22b and the chamfered portion 28 are pressed against each other and reliably locked.
The stacking tray combined box 1 as shown in FIG. 6 is completed by the above operation procedure.

  According to the stacking tray combined box 1 as described above, the lid is formed by folding the cover combined outer flap 21 and the cover combined inner flap 22 with respect to the side wall and the end wall in a flat plate state, and the upper opening / closing part can be closed. . Therefore, it is not necessary to provide a separate lid, and labor and manufacturing costs can be reduced. The lid portion 20 can be easily formed only by a bending operation similar to the inner flap and the outer flap of a general cardboard box. Furthermore, the stacking tray combined box 1 according to the present embodiment can be easily formed from one blank sheet 1a.

  On the other hand, when the lid / outer flap 21 is folded at the first boundary line and the lid / inner flap 22 is folded at the second boundary line, a frame-like support surface 25 is formed, and another stacking tray / box (see FIG. (Not shown) can be stacked. At this time, the tip corner portion 22 b of the lid / inner flap 22 enters the chamfered portion 28 of the lid / outer flap 21. And the side edge part 21a of the lid | cover outer flap 21 and the side edge part 22a of the lid | cover inner flap 22 are latched. Moreover, the operation | work which expand | deploys the lid | cover inner flap 22 from a latching state can also be performed easily.

  The embodiment of the present invention has been described above, but the present invention is not limited to the above-described embodiment, and can be appropriately changed without departing from the spirit of the present invention. For example, in the above-described embodiment, the chamfered portion 28 is formed in the lid / outer flap 21 and the notched portion 29 is formed in the lid / inner flap 22. However, the present invention is not limited to this. A notch portion may be formed in the lid / outer flap, and a chamfered portion may be formed in the lid / inner flap. In addition, a notch is formed on the side edge located on the left side (or right side) of the side edge part of the lid / outer flap and the side edge part of the lid / inner flap facing each other, and is located on the right side (or left side). A chamfered portion may be formed on the side edge portion. That is, the side edge part in which the chamfered part was formed should just oppose the side edge part in which the notch part was formed. And in the said embodiment, since the chamfering part 28 was formed in the lid | cover outer flap 21, since the lid | cover outer flap 21 was bent previously, when a chamfering part was formed in the lid | cover inner flap, First, fold the flap that is also used as a lid.

  Moreover, in the said embodiment, although A type type is employ | adopted as a shape of the bottom part 30, other well-known things, such as a one-touch bottom and an American lock, which do not need to use an adhesive tape etc. for sealing of a bottom part are also required.
