Abstract
A self-sealing, dispensing closure comprises a shell, a cover moveable axially toward and away from the shell, and a valve connected to the cover via a stem, and adapted to close the outlet when the cover is moved away from the shell and to open the outlet when the cover is moved toward the shell. The shell has a generally conical surface. The cover has a resilient skirt, which is discontinuous. The skirt engages the surface to bias the cover away from the shell and to bias the valve toward the closing position but to permit the cover to move toward the shell and to permit the valve to move away from the closing position. The shell and the cover have formations coactive to prevent the cover from being moved toward the shell and the valve from being moved away from the closing position at certain but not all positions of relative rotation of the shell and the cover.
