A nestable roll container includes a goods-supporting base wall (1) which is latched in a nesting condition by engagement of a pin (27) in a pocket (29) off a horizontal guide slot (28) formed through a vertical, laterally inner plate (18) of a wheelbox (5), the pin (27) being at the free end of an arm (26) pivotally mounted on the wall (1). When an adjacent lateral wall (7) is turned laterally inwards, as the wall reaches its end position of movement the pin (27) is lifted out of the pocket (29) by a lifting cam fixed to the inner end of a rigid strap (31) connected to the wall (7) and serving to limit laterally outward turning of the wall (7). Thus, the pin (27) is then free to slide forwards along the slot (28), to allow the base wall (1) to turn downwards into a horizontal position in which it engages in front wheel mountings (13). There are preferably two latching devices (26-29) and two releasing devices (32), one at each lateral side of the roll container. |
