Sharps container

A sharps container comprising in combination a hollow reusable outer container body and a disposable liner located inside the hollow outer container body to hold sharps, the outer container body having a thin wall, an open base and an openable closure means comprising a trap door which is normally located in a closed position for closing the open base and is moveable to an open position so that the liner can be replaced, and the combination having a mouth and a co-operating lid so that sharps can pass through the mouth and travel into the liner, the lid being used to close the mouth prior to disposal of the liner, the openable closure means being fitted to the outer container body below the liner so that when the trap door is moved to the open position the liner is automatically discharged from the container, the open base being braced about its lower periphery to inhibit flexing of the outer wall adjacent the trap door.
