A paint formulation and dispensing apparatus for mixing paint from a can having an open top and to a receiving can. The apparatus includes a dispensing lid attached to the paint can so that the lid overlies the open top of the paint can. The lid includes a spout and a reservoir having a plunger slidably disposed in it such that the position of the plunger determines the volume of the reservoir. A valve is disposed in a passageway in the lid and is movable between a first position in which the valve fluidly connects the passageway to the reservoir, and a second position in which the valve fluidly connects the reservoir to the spout. A weight scale is positioned below the spout and the receiving can is positioned on the weight scale. The weight scale generates an electronic signal to a programmed processor which generates output signals to control both the position of the valve as well as the position of an actuator which engages the plunger. |
