Pull actuated foam pump

摘要

A foam dispenser having an actuator and a dispenser housing. The actuator releasably mates with a pomp of a refill unit and is moveable from a first position to a second position. Wherein the second position is further from the refill unit than the first position. Movement of the actuator from the first position to the second position causes the foam dispenser to dispense foam when a refill unit is inserted in the foam dispenser.

1. A foam dispenser comprising:
a dispenser housing; an actuator secured to the dispenser housing; the actuator configured to releasably mate with a liquid pump of a refill unit, wherein the liquid pump is mated to a container that is provided as a single unit that is filled with a foamable liquid; an air pump; the actuator movable from a first position to a second position; the second position being further away from the refill unit than the first position; movement of the actuator from the first position to the second position causes a piston in the liquid pump to move downward away from the liquid inlet to pump foamable liquid out of the liquid pump, causes pressurized air from the air pump to mix with foamable liquid from the refill unit and causes the dispenser to dispense foam when a refill unit is installed in the foam dispenser.
