The metering device consists, for example, of a closure, having a closure body (1) with sealing closing means (7), which can be placed in a sealing manner on the connector. The metering means of the closure consist of just two components. There is first, seated securely in the closure body (1), a hollow cup (4) having, on the bottom side of the cup (4), a window (12) arranged in its side wall. The second component is a cap-shaped metering piston (10) having, on the upper side of the cap, a projection (5) which extends in the axial direction. This metering piston (10) with projection (5) fits into the cup (4), wherein its projection (5) covers and closes the window (12). The metering piston (10) is able to move axially in the cup (4) and its projection (5) is able to pivot to a limited degree toward the outer side of the window (12). In the pivoted-out state, it forms, together with the cup (4), an open valve which is otherwise closed. |
