The dosing device consists, for example, of a closure that can be sealingly mounted on the neck and that comprises a closure body (1) with sealing closing means (7). The dosing means of the closure consist of only two components. The first component is a hollow cup (4) which is fixed into the closure body (1) and comprises a window (12) disposed in the side wall of the cup (4) on its base side. A cap-type dosing plunger (10) constitutes the second component, the plunger comprising a projecting part (5) extending in an axial direction on the upper side of the cap. Said dosing plunger (10) with its projecting part (5) fits into the cup (4), wherein the projecting part (5) covers and closes the window (12). The dosing plunger (10) can be moved axially in the cup (4) and the projecting part (5) of said plunger can be pivoted by a limited dimension towards the outer side of the window (12). When pivoted outwards the projecting part, together with the cup (4), forms an open valve that is otherwise closed. |
