Seal assembly for a replaceable liquid dispenser cartridge

A liquid dispenser, comprising:

• a housing configured to receive a liquid supply cartridge comprising a seal assembly for selectively sealing an open end of the liquid supply cartridge, the seal assembly comprising:
• a seal body configured to be received within the open end of the liquid supply cartridge, the seal body including an annular sidewall that extends between a first end and an opposite second end that includes a base wall having an opening defined by an annular sealing member, and a yoke that projects from the base wall so as to be coaxial with the opening and a central axis of the seal assembly;
• a shuttle movably retained within the seal body by the yoke and including a plunger configured to seal closed the opening, the shuttle being movable between at least a parked position wherein the plunger is fully received within the opening, an open position wherein the plunger is removed from the opening, and an intermediate closed position wherein the plunger is partially received within the opening;
• and
• a biasing element located between the shuttle and the yoke for biasing the shuttle in a direction toward the opening formed in the base wall of the seal body.
• a reservoir disposed in the housing and configured to hold a volume of the liquid product, wherein the reservoir includes an access port for receiving the open end of the liquid supply cartridge to place the liquid supply cartridge and the reservoir in fluid communication when the liquid supply cartridge is inserted into the housing;
• and
• a receptacle disposed in the housing and between the liquid supply cartridge and the reservoir, the receptacle including a recessed hub having an actuator arranged in an opening formed in a base of the recessed hub, wherein the recessed hub is received in the access port of the reservoir and configured to receive the open end of the liquid supply cartridge such that the actuator is configured to move the shuttle from the parked position to the open position to place the liquid supply cartridge and the reservoir in fluid communication.
