ABSTRACT:
The device of the invention permits the dispensing of measures of a given volume of a liquid contained in a deformable container. It provides increased safety. It comprises in particular a one-piece displaceable safety element (5) comprising an upper gripping part (6) having a transverse closing face (7), a hollow central part forming a valve (8) and a lower part (9) forming a slide and outlet orifice, also hollow. This safety element thus comprising an axial hollow (10) is mounted so as to slide axially on the tube (1) via its lower part (9) between two limimt positions where it may be held. In the lowre closed position where the central part (8) of the safety element (5) is active, it then prevents the passage of liquid from the container to the cup via the tube (1) and its feed and outlet holes (3). In the upper open position, where this passage is made possible via axial and lateral holes (11) in the lower part (9) and and axial hollow ( 10) with which they communicate, the central part (8) is then inactive, the upper gripping part (6) of the safety element (5) projects permanently, at least partially, from the cup, the safety element (5) being such that, once the cap has been removed by the user, the latter must, in order to be able to use the device for dispensing measures, deliberately move the safety element (5) from its lower closed position to its upper open position by activating the upper gripping part (6).
