  • Patent number: 10252230
    Abstract: A tinting machine (1) comprising one or more dispenser heads for dispensing colorant into a paint container (3), the one or more dispenser heads comprising a fluid outlet (16) for discharging the colorant into the paint container (3), an internal chamber (19) opening in the fluid outlet, and a piston (25) that is longitudinally and movably arranged inside the internal chamber. An outer side surface of the piston and the inner surface of the internal chamber define an annular space (29) and the piston comprises a circumventional protrusion (26) defining a constriction (28) in the annular space. By supplying cleaning fluid to the internal chamber and moving the piston between a first and a second position, the internal chamber can be cleaned from residual colorant with a small amount of cleaning fluid. The invention further relates to a method for dispensing one or more colorants into a paint container using such tinting machine.
