Abstract: A fluid dispenser includes a dispenser housing, a container for holding a foamable liquid, a foam pump, an outlet in fluid communication with the foam pump, and a vacuum actuated suck-back mechanism in fluid communication with the foam pump and the outlet. The foam pump has a liquid pump portion and an air pump portion. The vacuum actuated suck-back mechanism includes a chamber and a movable member. The chamber has a vacuum port that is in fluid communication with the air pump portion of the foam pump, and a suck-back port that is in fluid communication with the outlet. The movable member of the vacuum actuated suck-back mechanism moves under vacuum pressure to reduce the volume of the chamber. The volume of the chamber increases upon removal of the vacuum pressure.

Abstract: A fluid dispenser includes a housing, a pump, an outlet nozzle, a reservoir, a liquid passage, an air passage, and a refill container. The pump and reservoir are attached to the housing, and both the outlet nozzle and the reservoir are in fluid communication with the pump. The reservoir has at least one engagement member, and the liquid passage and the air passage are located in the engagement member. The refill container has at least one sealing member, and the refill container is configured to be releasably attached to the reservoir such that the refill container is in fluid communication with the reservoir. When the refill container is attached to the reservoir, the engagement member engages the sealing member to cause the liquid passage and the air passage to be in fluid communication with the refill container.
