Abstract
A dual cartridge dispenser. Each cartridge has an exit orifice through which fluid is dispensed when a pump portion of the cartridge is compressed. A movable compression member in the dispenser can be located at a first position adjacent the pump portion of the first cartridge or at a second position adjacent the pump portion of the second cartridge. A knob extending outside the dispenser is connected to the compression member for moving the compression member to the first position or to the second position to thereby select the cartridge to be dispensed from. When a movable dispensing member of the dispenser is operated, it causes only the cartridge pump portion that is adjacent the compression member to be compressed between the compression member and an opposed pinch surface in the dispenser thereby dispensing fluid from the cartridge.
