Abstract: An injection needle (10) for a delivery head (30) for fluid products, such as for example pigments or coloring products, inside a container containing a paint base to obtain a coloring product, comprises internally an axial hole (20) which develops along a first central axis (X) for the passage of the fluid product toward a delivery opening (23). A channel (22) is provided to connect the opening (23) with the axial hole (20). The channel (22) develops along a second axis (Y) inclined by a desired acute angle with respect to said first axis (X).

Abstract: An anti-drying device (10) is to humidify a delivery unit (21) for fluid and semi-fluid products, pastes, gels, creams such as for example coloring products, pigments or paints, of a machine (75) for the automatic delivery of a fluid product in a closed container (11). A closed container or receptacle (79) inside which there is a fluid, liquid and/or vapor. The container (79) is configured to house, inside it, the delivery unit (21) to prevent the delivery unit from drying out.

Abstract: A device (10) to dispense fluid products into a container (12) provided with a closing portion (13) comprises delivery means (11) to deliver the fluid products into the container (12). The delivery means (11) comprises at least a tubular element (14) having a perforation end (34), by means of which the tubular element (14) perforates the closing portion (13) in order to make a delivery hole (16) in the closing portion (13) and is inserted, at least partly, into the container (12) in order to dispense at least one of the fluid products.

Abstract: A delivery device for fluid products including a plurality of containers, to contain a predetermined fluid and connected to an associated delivery unit provided with a piston unit. The device also includes a support on which the containers are mounted. The support rotates to position sequentially, at different moments of time according to one or more predetermined sequences, at least some of the delivery units in a predetermined delivery seating, to deliver corresponding quantities of fluid to obtain a desired fluid composition. Each delivery unit is provided with at least a disk type delivery valve, able to be activated between at least two distinct open conditions and a closed condition.

The delivery device contains stirrers, associated with the containers to mix the fluids contained in the containers. At least some of the stirrers are able to be selectively activated, independently of each other, to maintain the corresponding fluid in optimum conditions to allow an efficient delivery by the corresponding delivery unit disposed in the delivery seating.
