The present invention relates to a doser device which determines a priori the volume of an alcoholic drink that a person can drink so as not to exceed a given alcoholemia ratio in the blood of said person. The device of the invention comprises a container having a known volume and presenting various graduations: one graduation for the user's weight (expressed in kilograms), one graduation for the volume of the container (expressed in centilitres) and one graduation for the alcohol content of various drinks (expressed in degrees). Said three graduations are set on the container and are connected through lines forming together a reading chart, in order to read the volume variation of the various alcoholic drinks according to the weight and sex of the user, to correspond to the same predetermined alcoholemia percentage. The line of level of the liquid poured into the container is determined simply by observing its crossing with the reading chart. The device of the invention is particularly intended to the preventive control of alcoholemia when driving.
