A cap is provided for closing the opening when the container is filled. A continuous seal is effected between the lid and container by a pair of generally parallel spaced apart interior and exterior flanges defining an open bottom channel around the periphery of the lid. The channel is of a size and shape to receive the upper portion of the container sidewall in fluid tight sealed relation therein with the interior flange extending downwardly into the container. Coacting fasteners on the lid and container sidewall secure the lid in sealed relation onto the container. The lid may be fitted with a sealing gasket or flexible flange in the open bottom channel to effect further sealing of the lid. ## Claims ### Claim 1 A medical apparatus disposal container, comprising, an open topped container having a bottom wall and peripheral side wall interconnected to define a receptacle for fluids, said peripheral sidewall having an upper portion, having interior and exterior surfaces a lid for said container, said lid having a periphery and comprising, a top wall having an opening through which medical apparatus may be disposed into said container; means for closing said opening upon filling said container with medical apparatus; sealing means for sealing said lid onto the upper portion of said sidewall; coacting fasteners on said lid and container sidewall, said fasteners being operative to secure said lid in sealed relation on the upper portion of said sidewall in a fully installed position, said sealing means comprising a pair of generally parallel spaced apart interior and exterior flanges depending from said lid to wall and defining an open bottom channel around the periphery of said lid, said channel being of a size and shape to receive the upper portion of said container sidewall in fluid tight sealed relation therein with said interior flange extending downwardly into said container, said interior flange having a vertical depth greater than that of said exterior flange whereby insertion of said interior flange into said upper portion of said container sidewall is greatly facilitated. ### Claim 2 (depends on 1) The medical apparatus disposal container of claim 1 wherein said interior flange is of a size and shape to form a continuous seal with the interior surface of said upper portion of the sidewall at a position of the lid above its fully installed position in which said coacting fasteners are operatively engaged. ### Claim 3 (depends on 2) The medical apparatus disposal container of claim 2 further comprising a bead on the exterior surface and substantially at the top of said upper portion of said container sidewall arranged for engagement with the interior surface of said exterior flange. ### Claim 4 (depends on 3) The medical apparatus disposal container of claim 3 wherein said exterior flange has an interior surface which substantially conforms to the exterior surface of the upper portion of said sidewall. ### Claim 5 (depends on 2) The medical apparatus disposal container of claim 2 wherein said interior flange and interior surface of said upper portion of the sidewall are of a size and shape to provide an interference fit therebetween in the fully installed position of said lid. ### Claim 6 (depends on 5) The medical apparatus disposal container of claim 5 wherein a gasket is positioned between said interior and exterior flanges, adjacent and throughout said open bottom channel such that when said lid is in the fully installed position, said gasket is in fluid sealing contact with the top of said side wall upper portion. ### Claim 7 (depends on 6) The medical apparatus disposal container of claim 6 wherein said gasket is of a size and shape which allows said gasket to contact said top of said side wall upper portion prior to the lid achieving a fully installed position such that sealing contact is made in spite of irregularities in the top of said side wall upper portion. ### Claim 8 (depends on 7) The medical apparatus disposal container of claim 7 wherein said gasket is a rubber material. ### Claim 9 (depends on 3) The medical apparatus disposal container of claim 3 further comprising a flexible flange connected between and adjacent said interior and exterior flanges substantially at said open bottom channel and extending outwardly therefrom, and through the channel such that when said lid is in the fully installed position, fluid sealing contact is made between said flange and the top of said side wall upper portion. ### Claim 10 (depends on 9) The medical apparatus disposal container of claim 9 wherein said flexible flange is sized and constructed of a material such that said flange is bent away from said interior flange in response to contact with said side wall upper portion top and increasing the surface area contacted. ### Claim 11 (depends on 1) The medical apparatus disposal container of claim 1 wherein said coacting fasteners comprise a plurality of hooks and eyelets arranged in vertically registered relation on said lid and container. ### Claim 12 (depends on 11) The medical apparatus disposal container of claim 11 wherein said hooks are integrally formed downward projections on the exterior flange of said lid. ### Claim 13 (depends on 12) The medical apparatus disposal container of claim 12 wherein said eyelets are integrally formed on said container sidewall for receiving said hooks in snap fit relation therein in the fully installed position of said lid on said container. ### Claim 14 (depends on 1) The medical apparatus disposal container of claim 1 wherein said lid top wall includes a raised chimney portion around said opening and said means for closing said opening comprises a closure cap adapted to fit onto said chimney portion. ### Claim 15 (depends on 14) The medical apparatus disposal container of claim 14 wherein said cap includes a plurality of locking members and wherein said chimney portion includes a top having openings to receive and retain said cap locking members, securing said cap into place. ### Claim 16 (depends on 15) The medical apparatus disposal container of claim 15 wherein said lid further comprises a raised tower portion for storage of said closure cap at a position displaced from said opening.
