Abstract
Provided is a liquid dispensing package for a container adapted to contain a liquid that includes a hand operated liquid transport assembly coupled to an actuator, a liquid distribution subsystem in fluid communication with a discharge tube from the liquid transport assembly, wherein downward motion of the actuator, provided by a user, causes liquid to travel through the discharge tube to the actuator top surface, and a liquid draw-back subsystem wherein upward motion of the actuator, provided by a return spring, permits draw-back of liquid from the top surface of the actuator.
Claims3
A liquid dispensing package comprising:
- a container adapted to contain a liquid;
- an actuator having an actuator top having an actuator top surface with at least one discharge orifice in fluid communication with the container to permit flow of liquid from the container to the actuator top surface upon downward motion of the actuator;
- a liquid transport assembly coupled to and in fluid communication with the container and in fluid communication with the at least one discharge orifice;
- and
- the liquid transport assembly including a piston pump and a bellows suction component, said bellows suction component in fluid communication at a lower end with the piston pump and at an upper end with the at least one discharger orifice;
- wherein the at least one discharge orifice permits draw-back of liquid from the top surface of the actuator through the at least one discharge orifice upon upward motion of the actuator and an associated expansion of the bellows suction component.
