The neck of the bottle and the skirt of the trigger dispensing head are engageable with each other exclusively in a relevant predefined angular position, wherein the axial snap-engagement between the skirt and the neck is allowed.

Abstract: A trigger-operated dispensing device for a liquid comprising a tang (12) applied to the exit duct, a nozzle (30) applied to a tang, an insert (60) applied to the nozzle (30), axially bound and rotatable around the dispensing axis (X), provided with two openings (62, 64) for dispensing the liquid as a spray or as a foam. The insert (60) comprises an obturator (68), shaped to close/open the device.

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: 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) 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 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.

Abstract: A closure for a liquid container is provided between the container and a liquid dispenser head. The closure includes an intermediate body between the dispenser head and the container. The dispenser head can be rotated with respect to the container, without unscrewing the closure, except when the intermediate body is manually prevented from rotating.

Abstract: A connection system between a dispenser head of a liquid and a container of a liquid includes a base area of a structure and a flange screwed tight onto the neck of the container. Free rotation of the structure is prevented by a resistant torque, but the base area of the structure is made in such a way as to allow the accidental rotation of the head without unscrewing the flange.

Abstract: The invention relates to a fluid dispensing device with an elastic return or a biasing component that is outside the pumping chamber. When the trigger to the pump is activated the elastic return twists forming a torsion return force. The arrangement improves reliability of the pump device significantly.

Abstract: The present invention relates to a closing system for a container, comprising a neck of the container and a closing body. The body wall comprises at least one flexible tongue and at least one relatively stiff protrusion that, when the tongue is seated in the seating portion, arranges circumferentially sided to a circumferential stopping projection of the neck. In an imminent interference configuration, reached by relative rotation between the neck and the closing body, the protrusion interferes with the circumferential stopping projection for making an obstacle to the further rotation in the same direction of rotation, while the tongue is free from interferences with further obstacles to rotation.

Abstract: A device for dispensing at least one fluid comprises pumping means comprising an elastic deformable membrane (2) having a wavy annular wall (16) for producing a desired stiffness or pliability for said membrane (2). A pumping element (1) comprises a base (4) and said elastic deformable membrane (2).

Abstract: A trigger dispensing device for the concurrent dispensing of two or more fluids separately kept in a tank is disclosed. The dispensing device comprises a deformable elastic membrane whose pumping elements can be affected by a trigger for dispensing fluids. Membrane is held in position between a frame and a counter frame, whereas trigger is hinged to an arm of the counter frame. The device is provided with a delivery valve and with a check valve integrated in the membrane. The device is adapted for the concurrent dispensing of two or more fluids and is provided with a structure comprising a reduced number of components.

Abstract: The present invention is a fluid dispensing device, connectable/disconnectable to/from a container. The device, actuable by a trigger, comprises both closing means comprising a turnable nozzle and means for locking the sliding of a dispensing piston.
