Abstract: A medical waste disposal system that allows for the "hands-off" disposal of medical waste. The system comprises a wall mounted outer container which is extended away from the wall upon which it is mounted. The outer container has an aperture for the receipt of medical waste and members extending from this aperture into its interior which automatically open an inner container when the inner container is inserted into the outer container. The automatic opening occurs when the members contact and force open tabs located on the inner container. These tabs are positioned to align with the members and are resiliently biased to the closed position so that the inner container automatically closes when it is removed from the outer container. The inner container may be removed without direct human contact by fully opening an access door located in the base of the outer container, thereby allowing the inner container to fall free of the system.
