Abstract: A trigger dispensing head applicable to a bottle of a trigger dispensing device is provided. The trigger dispensing head has a cylinder chamber, a main vent passageway, a sleeve, a secondary vent passageway, an axially slidable piston, a suction duct, and a dispensing duct. The sleeve is rotatable by a user between an angular working position in which the main vent passageway is in fluid communication with the secondary vent passageway and an angular rest position, in which the main vent passageway is fluidically separated from the secondary vent passageway.

Abstract: A head (10) of a trigger dispensing device (1) for liquids includes a pre-compression valve (104) disposed in the upper region of the head. The valve (104) has an obturator wall (106) that cooperates with a mouth wall (102) to prevent the passage of liquid. The mouth wall (102) includes a sealing section (102a) with which the obturator wall (106) is sealingly engaged to slide during a pre-compression step of the liquid.
