  Embodiments of the present invention will be described below with reference to the accompanying drawings. This tray accommodates four strawberry packs, and as shown in FIG. 1, is composed of a tray body 1 in which cardboard sheets are punched and blanks of partition walls 2 and 3.

  In the blank of the tray body 1, a side wall 12 is connected to the long side of the bottom wall 11, and an end wall 13 is connected to the short side, and the side wall 12 sequentially extends from the bottom wall 11 to the outer plate 14, the top plate 15, and the inner plate 16. The end wall 13 is formed by connecting an outer end plate 17, a top plate 18 and an inner end plate 19 sequentially from the bottom wall 11. A support piece 26 is connected to the distal end edge of the inner end plate 19, and a leg portion 26 a is provided on the base end side by cutting into the inner end plate 19.

  Folding pieces 21 are connected to both end edges of the inner plate 16, and folding pieces 22 are connected to both end edges of the outer plate 14, and a joint portion 21 a is provided at the tip of the folding piece 21. A widening engagement piece 22 a is formed in the middle portion of the folding piece 22 by cutting, and a square-shaped engagement hole 21 b is provided in the middle portion of the folding piece 21.

  Square bars 18a are connected to both sides of the front end of the outer end plate 17, insertion pieces 18b are connected to the outer edges thereof, and insertion holes 15a are provided to both ends of the top plate 15, respectively. Locking holes 16 a having oblique edges are provided at both ends of the inner plate 16.

  Further, a V-shaped insertion hole 16b into which both end portions of the partition wall 3 are inserted is provided in the center portion of the inner plate 16, and both ends of the partition wall 2 are extended from the center portion of the top plate 18 to the inner end plate 19. A slit-like insertion hole 18c into which the portion is inserted is provided.

  On the other hand, in the blank of the partition wall 2, in order to mesh with the partition wall 3, a Y-shaped cut groove 2a is formed at the center of one long side, and the tray body 1 is inserted at both ends of the other long side. An insertion protrusion 2b to be inserted into the hole 18c is provided.

  Moreover, in the blank of the partition wall 3, a pair of support piece 32 is provided continuously, and the leg part 32a is formed in the connected part by alternate cutting. Insertion protrusions 32b to be inserted into the insertion holes 16b of the tray body 1 are provided at both ends of each support piece 32, and the central part of the long side of the support piece 32 is cut to engage with the partition wall 2. A groove 3a is formed.
