Further, when the middle leg plate 51 of the adjacent second pack insertion port 44 is bent downward along the third lead rule 55, the middle leg plate 51 is separated from the frame plate 41 along the first cutting line 56, and the engagement protrusion The piece 52 and the engaging recess 53 are crossed to be locked. Then, the holding pieces 48 of the first pack insertion opening 43 and the second pack insertion opening 44 are bent downward along the second lead ruled lines 49.

  Thereafter, when the frame plate 41 is inserted into the tray main body 11 so that the side wall 15 of the tray main body 11 is sandwiched between the inner wall 61 and the outer wall 63, the tip of the end leg plate 45 and the tip of the middle leg plate 51 are connected to the tray main body 11. Ground to the bottom wall 13. Then, the locking piece 73 of the cover member 40 is bent inward along the sixth folding line 75, inserted into the first locking hole 21 and locked to lock the outer wall 63 to the side wall 15. The tray 10 is completed.

  In the state where the tray 10 is completed, as shown in FIG. 7, the dimension L1 of the side wall 15 is larger than the dimension L2 of the inner wall 61, so that the frame plate 41 is between the bottom wall 13 of the tray body 11 and the upper end of the side wall 15. It is located and is horizontally arranged in a state of floating from the bottom wall 13. Since the outer wall 63 of the cover member 40 is disposed along the outer surface of the side wall 15 of the tray body 11 from the upper end to the lower end, the outer wall 63 reinforces the side wall 15 in the vertical (compression) direction. The lower portion of the side wall 15 is formed in a double wall structure by the outer wall 63 and the side wall 15, and the upper portion of the side wall 15 is formed in a triple wall structure by the outer wall 63, the side wall 15, and the inner wall 61. The rigidity of the part can be increased. Furthermore, since the outer wall 63 is only disposed along the outer surface of the side wall 15, workability during assembly can be improved. Since the outer wall 63 and the side wall 15 form at least a double wall structure, the side wall 15 itself does not need to be a double wall. This eliminates the difficulty of bending the adjacent end wall 25 and side wall 15 into a double wall, and improves workability during assembly.

  In addition, different printing can be performed on the cover member 40 according to the purpose, and the same type of tray can be used for storing different products. Furthermore, since the inside of the tray main body 11 can be printed in advance before the cover member 40 is assembled to the tray main body 11, the cosmetics of the tray 10 is improved.

  Since the side wall 15 has a horizontal direction, the pressure resistance when the trays 10 are stacked is low. However, the step direction of the outer wall 63 is a protruding direction of the outer wall 63 that extends in the up-down direction in the assembled state. Therefore, even when a compressive load is applied to the double wall composed of the outer wall 63 and the side wall 15, the compression direction and the step direction of the corrugated cardboard sheet coincide with each other, so that the compressive strength of the double wall structure can be increased.
