A tinting machine () comprising one or more dispenser heads for dispensing colorant into a paint container (), the one or more dispenser heads comprising a fluid outlet () for discharging the colorant into the paint container (), an internal chamber () opening in the fluid outlet, and a piston () 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 () and the piston comprises a circumventional protrusion () defining a constriction () 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.

Tinting machine and method for dispensing colorant into a paint container with base paint

A painting apparatus comprising a paint module, an applicator assembly, and a dip-tube assembly containing a pump, the paint module having a container receiving section which is closeable by a releasably attachable lid, the applicator assembly being fluidly connectable to liquid in the container receiving section via the dip-tube assembly, in which the lid includes an aperture to allow the dip-tube assembly to pass therethrough and submerge the pump in the liquid (FIG.).

Painting apparatus

A painting apparatus comprising a paint module, an applicator assembly having an applicator surface, and a pump, the paint module having a container receiving section, the applicator assembly being fluidly connectable to the container receiving section such that the pump can supply liquid contained in the container receiving section to the applicator assembly, in which the apparatus can operate in a painting cycle where the container receiving section receives a paint container with a supply of paint such that the paint can be supplied to the applicator assembly, and in a cleaning cycle where the container receiving section receives a liquid in the form of a cleaning fluid, such that the cleaning fluid can be supplied to the applicator assembly (FIG.).

A paint roller assembly comprising a primary roller () and a secondary roller (), the secondary roller being positioned relative to the primary roller such that paint supplied to the roller assembly passes over part of the secondary roller before being fed onto an exterior surface of the primary roller.
