A waste disposal container having a non-removable, permanently sealing, threaded closure. The closure consists of a outer cap and a inner, threaded base cap having one-way, interengaging ratchet teeth which affixes the closure to the neck of a waste disposal container. When the base cap is threaded on the threaded container neck, suitable adhesive is applied to the interior threads of the base cap and to the exterior threads on the container neck thereby permanently sealing the container.
