JPH02501628A - dual fluid cartridge dispenser - Google Patents

Abstract

The problem with single cartridge dispensers is that when a maintenance person looks at the liquid level of the cartridge, the fluid may be only slightly above the level indicator window with the result that the cartridge would be completely used up before the maintenance person returns to service the dispenser. Thus, it would be desirable to have two cartridges so that the user can completely exhaust one cartridge and then begin dispensing from the second cartridge. The device (10) employs two cartridges (11a,11b) each having a compressable dispensing pump (25a, 25b). A movable compression member (52) is slidable to a first position adjacent the pump (25b) of a first cartridge (11b) or to a second position adjacent the pump (25a) of the second cartridge (11a) so that fluid from only one cartridge may be dispensed at a time.
