Abstract (en)
[origin: WO2005107954A1] The invention relates to an airless dispenser which is used to dispense low doses of liquid products. The inventive dispenser is characterised in that it consists of: a first part (1) comprising a spray nozzle (10) which is communicated with a network of channels (12) on the wall of an inner truncated-cone-shaped bore (13), and a second part (2) comprising a deformable container (21) which is equipped with a rigid flange (23) for fixing the first part in the aforementioned bore. The outer periphery of the flange comprises an inclined surface (22) which defines a vortex chamber, opposite the above-mentioned network of channels (12), and which, together with the wall of the first part, forms an internal peripheral outlet groove (25). The outlet groove is defined radially by a flexible lip (20) forming an inlet valve which is supported by the first or second part.
