    Abstract: A fluid dispensing system including a fluid dispenser that is operable in a stand-alone mode, and a housing that is configured to removably receive the fluid dispenser for operation of the fluid dispenser in a housed mode. When the fluid dispenser is placed on top of a horizontal support surface for operation of the fluid dispenser in the stand-alone mode, a pump mechanism of the fluid dispenser is manually activatable to dispense an allotment of fluid by manually depressing an activation member of the pump mechanism. When the fluid dispenser is received by the housing for operation of the fluid dispenser in the housed mode, the pump mechanism is activatable by activating an actuation mechanism of the housing.

    Abstract: A trigger sprayer includes an engine with a piston chamber and an outlet fluid passage, and a piston that slides within the piston chamber and defines an interior bellows chamber. The bellows component is movable in the interior bellows chamber between an uncompressed position in which a fluid volume in the interior bellows chamber is minimized and a compressed position in which the fluid volume is maximized. The trigger sprayer further includes a trigger lever that pivots between a neutral position and an actuated position using a pair of S-shaped trigger springs. Pivotal movement of the trigger lever pushes the piston vertically in the piston chamber to drive fluid from the piston chamber into the interior bellows chamber and move the bellows component from the uncompressed position to the compressed position. Relaxation of the bellows component drives fluid from the interior bellows chamber to the outlet fluid passage.
