Abstract: A trigger dispenser device (1) envisages a secondary liquid aspiration duct (50) in communication with the dispenser duct, and a primary liquid aspiration duct (8) in communication with the container, off-axis with each other. Between these, a joining compartment (64) is provided communicating upstream with the primary liquid aspiration duct (8) and communicating downstream with the secondary liquid aspiration duct (50) to form the fluidic connection between them. In particular, the container (C) is of the type with built-in suction pipe.

Abstract: A trigger dispenser device (1) comprises a container (C) provided with a dip tube, a dispenser head (20) with a primary liquid aspiration duct (8) connectable to the auxiliary liquid aspiration duct (202) of the container (C) and eccentric with respect to the container axis (X).

Abstract: A trigger dispenser (1) for liquids comprises a suction valve (30) comprising a diaphragm (32) housed in the pumping chamber (4) and a delivery valve (60), separate from the suction valve (30), comprising a baffle (62) external to the dispensing pipe (14). The diaphragm (32) of the suction valve (30), during liquid dispensing, abuts on the bottom wall (10b) of the pumping chamber (4) land covers the suction opening (6a), and the baffle (62) of the delivery valve (60), during the return, abuts on the crown surface (18) which surrounds the inlet opening (14a) of the dispensing pipe (14).

Abstract: A trigger dispenser (1) for liquids comprises a suction valve (30) having a diaphragm (32) abutting against the bottom wall (106) of the pumping chamber (4). The suction valve (30) comprises a stem (40) extending along a suction valve axis (Y), which crosses the bottom wall (10b), snap-coupling with it.

Abstract: A trigger dispenser device (1) is for dispensing a liquid comprises a container (C) and a dispenser head (20). The head includes a frame (22) having a pressure chamber (24) and a secondary liquid aspiration duct (50), and an auxiliary body (2) attached to the frame (22). The auxiliary body is provided with a primary liquid aspiration duct (8) and an air aspiration chamber (4b). Between the frame (22) and the auxiliary body (2) a merger compartment (64) is formed and the air aspiration chamber (4b) surrounds the merger compartment (64) so as to seal it.

Abstract: A dispenser device head (1) of a liquid is provided with a nozzle (20) comprising a lateral wall (30) having through signalling apertures (40) defining a caption or symbol to highlight a functioning configuration.

Abstract: A dispenser head (1) comprises a main body (2), an arm (60) hinged to the main body (2) and pumping means. The pumping means comprise a main cylinder (12), a sliding piston (16), dispensing means sensitive to pressure. The arm (60) is hinged to the main body (2) in a hinging portion (60b) distanced radially from the body axis (X), straddling the body axis (X) and transmitting an axial translation movement to the piston (16) by means of an elastically yielding element (30). A removable lock or tab can be included as a safety means.
