Abstract
A container for contaminated materials having an upper entry chute (29) and a hinged door (12) which normally hangs vertically closing the inner end of the chute. When the container is full the door (12) can be lifted until hooks (39) at its lower end engage in apertures (42) in the lid of the container and the whole lid can then be pivoted into a closed position closing the entry opening to the chute and thus providing protection from the contaminated chute surface (29). The door has barbed detents (44) which engage in apertures (48) to hold the door positively sealed in its final closed position. In the example illustrated in FIG. 6 there is a separate hinged closure (72) for closing the outer end of the entry chute.
