Disposal plug for filter cartridge.

摘要

A plug (12) is adapted for sealing a disposable filter cartridge (10). The plug is inserted into the axial opening (50) of the cartridge for temporary retention by the grommet. The plug (12) is then reversed and inserted into the grommet of the spent filter cartridge (10) for sealing the contents. The plug (12) is constructed to resist removal from the spent cartridge (10). A second plug embodiment seals with a sleeve-like grommet at two axial spaced positions. <IMAGE>
