ABSTRACT:
A reducible-volume cartridge for holding a viscous substance for use in combination with a dispenser of a pump-type utilizing a sub-atmosphere pressure to effect withdrawal of a predetermined amount of the substance from the cartridge for ejection through the dispenser, the cartridge having a hollow, annular body with identical ends, and a floating piston disposed for axial movement in a sealing manner within the cartridge thus forming a reducible chamber within the cartridge, the chamber holding the viscous substance on the side of the piston facing the dispenser, with the opposite side open to the atmosphere; the cartridge optionally having a wall formed midpoint its length to form a pair of chambers, with a pair of pistons disposed for axial movement, each within a chamber and each initially disposed adjacent the wall, the body and wall of the optional cartridge having a passage formed therein to expose each chamber to the atmosphere; either cartridge usable with the dispenser to discharge the substance from one chamber, then removable, rotatable to attach an opposite end to the dispenser, and re-usable to discharge substance from a refilled chamber, or from a second chamber.
