Formed. Reference numeral 6 denotes a reinforcing rib formed on the outer surface of the container at a distance from the flange 5. In this container, four pairs of supporting leg portions and pocket portions having point symmetry with respect to the center point O are formed on the long side walls 1 and 2 and the short side walls 3 and 4 as follows.
[0008]
In other words, the long side walls 1 and 2 have a point A composed of a supporting leg portion 7A and a pocket portion 8A in a point-symmetrical position, and a pair B composed of a supporting leg portion 7B and a pocket portion 8B in a point-symmetrical position. A pair C consisting of the support leg 7C and the pocket 8C at the symmetrical position and a pair D consisting of the support leg 7D and the pocket 8D at the point symmetrical positions are formed. The support legs 7A to 7D protrude outward from the outer surfaces of the long side walls 1 and 2. Further, the pocket portions 8A to 8D bulge a part of the long side walls 1 and 2 outward so that the inner surface of the container is recessed, and the support legs 7A to 7D are inserted into the pocket portions 8A to 8D. It is formed in a possible size. In addition, vertical streak-like gathering ribs 9A to 9D project from the outer surfaces of the long side walls 1 and 2 below the support legs 7A to 7D, respectively.
[0009]
On the other hand, the short side walls 3 and 4 have a pair G of a supporting leg portion 10G and a pocket portion 11G in a point-symmetrical position, and a pair H of a supporting leg portion 10H and a pocket portion 11H in a point-symmetrical position. A pair I consisting of the supporting leg portion 10I and the pocket portion 11I in the symmetrical position and a pair J consisting of the supporting leg portion 10J and the pocket portion 11J in the point symmetrical position are formed. The supporting leg portions 10G to 10J protrude outward from the outer surfaces of the short side walls 3 and 4. In addition, the pocket portions 11G to 11J bulge a part of the short side walls 3 and 4 outward so that the inner side surface of the container is recessed, and the support legs 10G to 10J are inserted into the pocket portions 11G to 11J. It is formed in a possible size. In addition, vertical streak-like gathering ribs 12G to 12J project from the outer surfaces of the short side walls 3 and 4 below the supporting leg portions 10G to 10J.
[0010]
Each of the pocket portions 8A to 8D and 11G to 11J is formed so that the bottom ribs are stepped so that the shifting ribs 9A to 9D and 12G to 12J can be fitted therein.
[0011]
Accordingly, in the present invention, the concave edge portion 13 which is lowered in a step shape is formed on the inner edge of the flange 5, and the inner peripheral edge of the flange corresponding to the corner portion of the container is at the same level as the concave edge portion 13. An arcuate concave edge portion 14 is provided which is lowered in a step shape and has a width dimension adapted to the outer dimension of the normal container for mounting the normal container position. Reference numeral 15 denotes a recess formed on the inner edge of the concave edge portion 13 so as to face the above-mentioned approaching ribs 9A to 9D and 12G to 12J.
