Metering device for precise dosing of different portions of the liquid dispensing material from a container

摘要

The invention relates to a dosing device for precisely dosing different quantities of a liquid product to be dispensed from a container. Said dosing device consists of a measuring compartment which can be fixed in a permanent or removable manner, can be closed by a cap, and is supplied with a liquid product to be dispensed from the container by means of an inlet, a guiding channel, and a discharge and suction opening, when the elastically deformable walls thereof are pressed together. A control and fixing element (3) is movably arranged on a fixed closing and guiding part (1) and connected thereto in such a way that each of its rotational movements systematically forces its pre-defined axial displacement which has a direct effect on a measuring compartment housing (2) connected to the closing and guiding part in a permanent but sliding manner. The entire axial displacement of the measuring compartment housing (2) is split into pre-defined sections which are respectively defined by an engagement of a fixing tongue (13) forming part of the control and fixing element (3) into a fixing nest (14) forming part of the measuring compartment housing (2).
