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.

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 pre-assembled dispenser head (10) for a dispenser device (1) of a liquid includes a frame (14), a connector (60) having a suction tube (62) for the liquid. The connector (60) is connected to the frame (14) by a snap-free connection.

Abstract: A head (4) of a trigger dispensing device for liquids includes an auxiliary body (30) for the connection with a neck (10) of a bottle (2). The auxiliary body (30) includes a closure base (32) suitable to close a mouth (13?) of the bottle (2) and dual constraints suitable to snap-engage with the neck (10) forming between the auxiliary body (30) and the neck (10) a constraint both to the relative rotation and to the separation thereof.

Abstract: A trigger dispenser device (1) for a liquid includes a dispenser head (20) provided with a pressure chamber (24) and a piston (26) sliding in the pressure chamber (24). A valve dispenser is provided to permit the passage of the liquid towards a dispenser duct (30) upon reaching a threshold pressure, and a trigger suitable for mechanically operating on dispenser valve to force the valve towards the open configuration.

Abstract: A trigger head for a dispensing device for at least two substances including a pumping system to compress the substances separately and simultaneously before dispensing.

Abstract: A trigger dispenser (1) for liquids comprises a suction valve (30) and a delivery valve (60), separate from the suction valve (30). The dispenser (1) has a detachable stop (100), comprising a bottom (104) positioned rearwards of the delivery valve (60) to form an end stop abutment with this during the dispensing step.

Abstract: The present invention relates to fluid dispensing devices for use in dispensing different liquids (e.g., bleach and bleach activator) from a bottle having first and second compartments. To minimize the presence of mixed composition residually present within the fluid dispensing device, it may be helpful to delay mixing. Separate dip tubes may be provided to pull liquid from the separate compartments, each with its own separate pump. Each pump may deliver the separate compositions to a spray nozzle of the device through separate delivery tubes (e.g., from the pumps to the nozzle). In other embodiments, a single delivery tube, and/or a single pump may be provided, e.g., where the volume of mixed composition that may be present in such pump and/or delivery tube may be sufficiently small so as to still provide overall desired efficacy characteristics. Dual delivery tube configurations may eliminate any need to prime the device by spraying out old, residual mixed composition.
