The trigger dispensing head has a cylinder chamber, a piston, a pressure chamber, a sleeve having an end wall, a suction duct terminating in a suction mouth, a dispensing duct, and valve members for regulating flow of a product. The valve members have a valve element made in one piece. The valve element has a tubular portion, a flexible flap, and an annular membrane.

Abstract: A trigger dispensing head applicable to a bottle suitable for containing a product to be dispensed is provided. The trigger dispensing head has valve elements having a dome-shaped valve body provided with an elastically deformable membrane. The elastically deformable membrane has an annular sealing ring that forms a head seal of a pre-stressing valve.

Abstract: A dispenser for pasty products which has a head, a pump, an actuator, and a container tube is provided. The pump is provided with a plurality of flexible flaps protruding inwardly from a dome-shaped elastically deformable cap of the pump or from a connection portion of the pump to form a lower or suction valve.

Abstract: A connection system between a dispensing head and a bottle of a trigger dispensing device includes a skirt having a seat configured as an inlet on an inner surface, and a neck having a rib protruding from an outer surface. In a relative assembled position, the rib is angularly aligned with the seat while, outside of the relative assembled position, the rib constitutes an impediment to axial insertion of the skirt on the neck.

Abstract: A dispenser for pasty products which has a head, a pump, an actuator, and a container tube is provided. The pump is provided with a flexible annular lip protruding out of the pump and inserted into an initial section of a dispensing tube of the head, configured to sealingly come into contact with an initial surface of the initial section to form an upper or delivery valve.

Abstract: A trigger dispensing head for a compact dispenser is provided. The trigger dispensing head has a frame, a piston chamber, a piston, a dispensing pipe, a trigger, and a return element having two arms. Each arm of the two arms is arranged in a respective part of a sagittal plane. A lower backing part, supported by the frame, has a main surface. Lower ends of the return element are in contact with the main surface and freely movable thereon.

Abstract: A dispensing head for a trigger dispenser includes a frame having a functional zone on which a frame port, a suction outlet port and a dispensing inlet port open. A valve device applied to the functional zone includes a suction shutter and a dispensing shutter that implements a precompression of products before dispensing. The valve device cooperates with a reference plane of the frame to form a precompression chamber upstream of the dispensing inlet port.

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 connection system between a dispensing head and a bottle of a trigger dispensing device includes a skirt having a seat configured as an inlet on an inner surface, and a neck having a rib protruding from an outer surface. In a relative assembled position, the rib is angularly aligned with the seat while, outside of the relative assembled position, the rib constitutes an impediment to axial insertion of the skirt on the neck.

Abstract: A connection system between a head and a bottle of a trigger dispensing device includes a main skirt having a first flexible tab and a neck having a first sloping plane and a first pocket. The first flexible tab extends circumferentially from a first end to a second end, and the first end is joined to an annular wall by a closing wall. The system also provides for an auxiliary window obtained through the annular wall of the main skirt, and a rigid auxiliary tooth of the neck, suitable to snap into the auxiliary window.

Abstract: A trigger dispensing head for a liquid dispensing device includes a chassis, a trigger, elastic return means having a return element supported by the chassis, and a reversible locking device. The locking device is supported by the return element of a non-return element.

Abstract: A dispensing device including a bottle provided with a neck and a trigger dispensing head fitted to the neck is provided. The dispensing head includes a socket at least partially housed in the neck compartment, a main body that, with the socket, delimits a valve compartment in the neck, a valve group, a piston, a chassis, a trigger group, and elastic return elements. The valve group is contained in the valve compartment, limiting the overall size of the device.

Abstract: A dispensing device for paste products, including toothpaste, is provided. The dispensing device includes a container, a pumping diaphragm and a head applied to the container. The head is equipped with a tube and a button for acting on the diaphragm and deforming it for dispensing. The button has a pressure surface for a user's dispensing action. An extension element which, in an active position, is arranged as an extension of the pressure surface of the button, increases a leverage effect.
