From the upper end of the side wall 2, a flange 3 extending horizontally is formed outward, and below the flange 3, near the opening of the large container B, the entire periphery of the outer peripheral surface of the side wall 2 is formed. An appropriate number of horizontal circumferential ribs 4 are provided extending horizontally so as to surround. In this embodiment, two horizontal circumferential ribs 4
a, 4b are formed. For convenience, of the two horizontal full-circle ribs 4a and 4b, the upper horizontal full-circle rib 4a is referred to as a first horizontal full-circle rib 4a, and the lower horizontal full-circle rib 4b is It will be referred to as a second horizontal entire circumferential rib 4b. Further, below the first horizontal full-circle ribs 4a and the second horizontal full-circle ribs 4b, each side wall 2 except for the corner of the large container B is provided.
One horizontal mounting rib 5 is formed over a predetermined length in the width direction of the outer peripheral surface of the main body. As shown in FIG. 3, the virtual plane formed by connecting the tips of the first horizontal full-circle rib 4a, the second horizontal full-circle rib 4b, and the horizontal mounting rib 5 is a vertical virtual vertical plane F1. The tip of the flange 3 is located inside the virtual vertical plane F1 as described later.

A vertical rib 6 having a width that does not protrude outward from the tip of the flange 3 is formed at a predetermined interval between the flange 3 and the first horizontal circumferential rib 4a.
Further, between the first horizontal full-circle ribs 4a and the second horizontal full-circle ribs 4b, and between the second horizontal full-circle ribs 4b and the horizontal mounting ribs 5, their tips are the above-mentioned virtual vertical surfaces. Vertical ribs 7, 8 flush with F1 are formed at predetermined intervals.

As shown in FIGS. 3 and 5, the side wall 2 has a lower side wall region 2a extending from the bottom 1 to almost the middle of the large container B, and a position above the upper end of the lower side wall region 2a. Region 2 formed almost in the middle of large container B
