This method consists in making such a dosing device by joining together two complementary parts, both moulded from a plastic material using the pressure injection moulding technique, namely a first part (1) simultaneously forming the pouring tube (4), the connector (3) and a portion (5) of the dosing reservoir, and a second part (2) forming the other portion of this dosing reservoir. These two parts are then connected at the place where the dosing reservoir (2-5) has a maximum cross-section, their joining together being performed by welding, gluing or fluid-tight engagement. The invention also relates to the dosing devices thus manufactured. <IMAGE>
