Abstract
Abstract A disposable receptacle for disposing of sharp and hazardous objects such as syringes, razor blades and similar objects discarded from clinics and hospitals, includes a generally box-like container preferably constructed of a rigid durable plastic having a circular opening in the top with a neck projecting from the opening and including a closure having a plurality of pie-shaped spring flaps forming a one way closure for permitting the insertion of objects but preventing the withdrawal of objects from the container. Shoulders project upward from the top of the container at each side of the neck with handles extending between the neck and shoulders providing handles for carrying, and forming slots therebetween for receiving a generally D-shaped lock strap member for lockably attaching the container to a vertical support surface preferably at an elevated position to reduce access by children and the like. Grooves are formed around the perimeter of the container for receiving straps for mounting the container.
