Container defining, by means of its fixed walls, a first volume capable of containing a fluid to be removed via an outlet orifice and a second volume connected to a supply of a second fluid under pressure, the volumes being respectively complementary and variable by moving an internal deformable diaphragm between a first position and a second position in which the first volume (fluid to be removed) has a maximum and minimum volume, respectively, characterised in that the said diaphragm is fixed by its peripheral edge onto the wall of the container. <IMAGE>
