Abstract:
A method and apparatus for dispensing of a product based on weight as a load cell (22) which supports a structure holding the product (20a) to be dispensed. The weight of the product (20a) that is dispensed is determined by use of a controller (23). A dispenser (200) dispenses an amount of concentrate using a diluent to form a use solution. The dispenser (200) includes a housing (201) having a cavity. A product holder (210) is positioned to support the concentrate in the cavity of the housing (201). A load cell housing (207) is operatively supported by the housing. More than one load cell (240) is positioned in the load cell housing (207). The product holder (2 10) is supported on the more than one load cell (240), wherein weight of the concentrate is determined. A dispenser (200) dispenses an amount of concentrate in a container (204) using a diluent to form a use solution. A dispenser includes a housing (201). A product holder (2 10) is positioned to support the container (204) with the concentrate in the cavity of the housing. The product holder (210) carried by a scale (240), wherein weight of the concentrate is concerned. A moveable container holder (215) is moveable between a first position and a second position. The container holder is positioned between the housing (201) and the container (204). A cover (216) is operatively connected to the container holder (215) at a connection. A cam surface is adjacent the housing (201). The cover (216) has a cam (216d) for contacting the cam surface (201 a), wherein when the cover (216) is moved from a closed position to an open position, the connection moves upward, thereby carrying the container holder (215) and the container (204) which are moved upward lifting the container (204) off of the product holder (2 10).
