Abstract
A disposable container for used items of medical equipment such as hypodermic needles, has an entry chute in its upper wall and an internal self-closing door flap which will swing downwards to allow an object to enter and swing upwards under gravity to close the chute. When the container is full a locking probe is inserted through a hole in the top wall, where it is locked by barbs and presses down a lever attached to the door to hold the door positively closed without any risk of accidental opening.
