Abstract: A dispensing head (1) for a trigger dispensing device includes a return spring (50) provided with a pair of main arms (52, 54), secondary arms (62, 64) which extend from the main arms (52, 54) and an abutment portion (70) that connects the secondary arms (62, 64). The abutment portion (70) and/or the secondary arms (62, 64) are applied to the frame (2) to create a constraint and give rise to a return action.

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: A vent for a liquid dispenser includes a vent flange comprising a flange body. The vent body includes a vent wall on which the membrane is applied. The vent wall extends parallel to the geometric axis of the device so as to have a sufficiently large area available for applying the transpiratory membrane and at the same time to limit the space occupied radially by the flange.

Abstract: A foaming device, capable of generating foam by mixing a volume of air with a quantity of liquid, optionally connected to a tank of the liquid and provided with valves for controlling the flow of air and liquid, comprises an air chamber enclosed in a resiliently deformable diaphragm, and a liquid chamber. The diaphragm is shaped in such a way as to produce an increasing rate of flow of expelled air during deformation by an air piston.
