Patent ID: 7757968

Claim:
A dispensing device configured to interface with a tank along a first axis, the device being adapted for dispensing a first fluid and a second fluid separately held respectively in a first containment chamber and a second containment chamber of the tank, the device comprising: actuating means comprising a trigger and adapted for being actuated by fingers of a user for the concurrent dispensing of the fluids; and pumping means adapted for sucking and dispensing the fluids, wherein the pumping means comprises: a first and a second pumping chamber, separate from one another, respectively fluidically associated to an intake duct and a dispensing duct, the pumping chambers exhibiting, in a rest configuration of the device, a maximum volume and in a dispensing configuration, a reduced volume, lower than the maximum volume, wherein the pumping chambers are at least partly delimited by deformable elastic walls, deformable by the actuating means along a second axis from the rest configuration to the dispensing configuration, wherein the deformable elastic walls are held in position by a counter frame of the pumping means, wherein the counter frame is directly connected to the trigger for opposing the trigger action on the deformable elastic walls, wherein the deformable elastic walls form a gap with a depression in the counter frame for fluidic association of the pumping chambers with the intake duct and the dispensing duct, and wherein the first axis and the second axis are substantially perpendicular.
