DRAIN DEVICE HOLDER AND CAPSULE TYPE CARTRIDGE

摘要

A manually operable ejector holder for a loaded capsule-like cartridge of cylindrical shape open at one end and provided with an annular flange at the open end, the other end being closed but provided with an angular discharge nipple and the holder having a cylindrical body provided with an ejecting plunger operated by a pivoted lever-type handle member. The forward end of the cylindrical body being partially cutaway in a radial direction for a limited distance longitudinally to provide a hollow seat to receive the flanged end of the cartridge and the seat having an undercut groove to receive the flange of said cartridge, and the sidewalls of the seat at the upper edges being of limited flexibility and spaced apart a slightly less distance than the diameter of the cartridge body to effect a limited snap-acting connection of the cartridge to the holder.
