Abstract: A closure device for use with a container having an open neck finish, including an inner cap having a skirt terminating in an open end which engages the outside diameter of the finish. The inner cap is sized to initially engage the finish. The skirt has circumferentially spaced slits extending, which may function as lyophilization ports, which permit the inner cap to expand upon an axial closing force and engage the bottom of the finish. A liner is positioned in the inner cap proximate the closed end and is compressed against the finish when the cap is moved to alignment with the bottom of the finish. An outer cap is locked on to the inner cap in pre-assembly which then encloses the inner cap after complete assembly to seal and compress the liner between the finish and the inside face of the inner cap.

Abstract: A rubber tire individual separation transport apparatus including a rubber tire individual conveyor surface section and a rubber tire sliding surface section separately formed on a slat conveyor surface, with the conveyor having a horizontal charge zone, a sharply inclined individual transport zone, and a horizontal discharge zone. Also included is an upright plate erected for contact with the peripheral surface of a rubber tire at one end of each slat in the individual conveyor surface section. A support plate of such a size as to support only one rubber tire laid flat on said individual conveyor surface is mounted at a larger pitch in the direction of transport than the maximum diameter of the rubber tire being conveyed. A stationary side wall is erected along the side edge of the other end of the slat of the sliding surface section. Cooperative action between the selected tire and the side wall causes frictional force on unwanted tires to cause them to fall back to the supply of tires.
