A roll container 100 with a movable base 140 directly pivoted to a pair of pivot arms (151, 152, Fig. 7) and indirectly pivoted on a back wall 110 with said pivot arms, the back wall 110 having side profiles (111, Fig. 6) on opposing lateral sides of the back wall. The pivoting mechanism 150 pivots a base 140 relative to the back wall between a deployed orientation orthogonal to the back wall, and a folded orientation at an angle less than orthogonal to the back wall. Pivot arms (151, 152, Fig. 7) of the pivoting mechanism are connected to the side profiles to be rotated about a first horizontal axis. The mechanism includes an axle (153, Fig. 6), extending between the pivot arms (151, 152, Fig. 7) and is offset from the first horizontal axis to create a second horizontal axis. The base is rotatably connected to the pivot arms through the axle so as to be rotated directly about the second horizontal axis and about the first horizontal axis at a radius of said offset allowing for nesting of such roll containers, as well as providing plural levels at which the base 140 may be mounted. |
