A container (1) has a hinged door (2) held closed by means of latching means (3). The latching means include a hook (4) controlled by a toggle mechanism comprising cranked levers (7) pivotally connected to the hook (4) by a pivot pin (8) slideable in slots (9). The cranked levers are pivotally connected to arms (11) fixed to a rotatable shaft (12). Also fixed to the shaft (12) is an arm (27) pivotally connected to a piston rod (15) carrying a piston (17) slidable in a cylinder (14). Holes (19) are provided in the crown of the piston and are covered by a washer (20) so that rapid acceleration of the shaft (12) in the direction necessary to release the hook (4) is prevented. |
