A pump dispenser, comprising:
- a container defining a cavity for storing a dispensable material;
- a pump body positionable in said cavity and having a pump chamber fluidly communicatable with a pickup chamber that is fluidly communicatable with a dispensation chamber, wherein at least a portion of said dispensation chamber is defined by a lumen of a flexible member to sealingly separate said dispensation chamber from said pump chamber, so that said pump chamber is fluidly communicatable with said dispensation chamber only through said pickup chamber, said pump body further including an intake opening communicating said cavity with said pickup chamber, and a central axis defining mutually perpendicular axial and radial directions;
- and
- a piston positioned at said pump chamber and slidably engaged with said pump body, said piston being axially movable in said pump chamber in a first axial direction to force airflow into said pickup chamber to an extent sufficient to carry the dispensable material through said dispensation chamber.
