Abstract

Process for withdrawing and pouring out a of measure of liquid from a reservoir with a view to pouring out the withdrawn measure, consisting in: withdrawing at least one measure of liquid simultaneously with the pouring-out of liquid; and transferring a measure into a metering chamber to await a further pouring-out. This process consists: (a) in isolating, from the reservoir, an amount of liquid corresponding to the measure of liquid to be poured out plus a surplus of liquid; (b) in utilizing the surplus liquid to guarantee complete filling of the metering chamber independently of the level of filling of the reservoir; (c) and in separating the surplus liquid from the measure of liquid simultaneously with the pouring-out of the said measure.

Dependent claims

Process for withdrawal and pouring out of a predetermined measure of liquid from a said liquid contained in a container (30), the process comprising at least one sequence whereby, from a normal position of the said container, in which the said container rests on its base (32), successively the container is inverted, top to bottom, and then the said container is returned to the normal position, this being in order to proceed to the stages required for withdrawal and metering of the said liquid, in which:

(a) from the contents of the container, a predetermined amount (Vp) of liquid, equal to the sum of the measure of the said liquid to be poured out plus a surplus of the said liquid is withdrawn and isolated from the said container, in a withdrawal chamber (40) (cf. FIG. 3);
(b) from the predetermined amount of liquid, a metering chamber (22) is filled by transfer from the withdrawal chamber (40), in order to obtain the said measure;
(c) and the said measure is poured out from the metering chamber (22) (cf. FIG. 5);
characterized in that, during stage (b), a predetermined surplus of the said liquid is retained in the withdrawal chamber (40) and, when filling of the metering chamber (22) is complete, this forms a column of liquid (Vs) charging the measure (Vd) to be poured out, and, during stage (c), the said surplus is retained separately in the withdrawal chamber (40) whilst the measure (Vd) of liquid is poured out simultaneously, away from the said surplus, from the metering chamber (22).
