Abstract
Disclosed is a mixing and dispensing system including a tubular housing with an inlet opening for receiving a first liquid ingredient and a tubular casing for retaining a second liquid ingredient to be combined therewith. A piston is longitudinally movable in the tubular casing to force the second liquid through an outlet opening that liquid tightly engages the inlet opening of the tubular housing. Extending through an end of the tubular housing opposite to the inlet opening is a rod having an inner end secured to a seal mechanism for contacting the inlet to liquid tightly seal the inlet opening. The rod also extends through and is longitudinally movable within a passage in a plunger having an outer periphery conforming to the inner walls of the tubular housing. A coupling mechanism is operable to selectively secure the plunger to the rod so as to provide common longitudinal movement thereof.
