ABSTRACT:
A cylindrical pump body is axially disposed in a container and has an annular shoulder sealingly abutting an outer end of the container neck opening. The wall of the pump body is press fit against the interior wall of the container neck. A cylindrical sleeve is telescopingly press fit within an outer end portion of the pump body and has an annular collar sealingly abutting the pump body shoulder. The press fit between these components as well as their abutting annular sections ensures securement of the components within the container as well as the sealing of container contents therein without the use of threaded closures of gaskets.
