Abstract
A liquid dispenser (10) for dispensing a liquid (16) from a reservoir (15) to a dispensing location is disclosed. The dispenser (10) includes a dispenser head member (11) adapted for engaging the reservoir (15). The head member (11) has a bore (18) having a first opening (18a) and second opening (18b). The first opening (18a) is proximate the reservoir (15) and the second opening (18b) is proximate the dispensing location. A stem member (19) is slideably mounted in the bore (20). The stem member (19) has a measuring cavity (21). The measuring cavity (21) is in fluid communication (15) when in a filling position wherein the liquid enters the measuring cavity and the measuring cavity (21) dispenses a given volume of product (16) from the measuring cavity (21) when in the dispensing position and when in a position intermediate the dispensing and filling positions the measuring cavity (21) is enclosed by the head member (11). A return spring (28) cooperatively connected to the first end of the stem member (19) and a cup (39) is cooperatively connected to the bottom of the stem member (19). The return spring (28) and cup (39) provide for moving the stem member (19) between a filling position and dispensing position based on the rise and fall of water caused by the spray action of a dishwasher.
