Abstract
In a plastic closure (), preferably configured as a screw cap, a capsule having a chamber () is formed with a capsule wall (), wherein said capsule is closed both by means of a flexible membrane () and by means of a film () which seals the chamber (). An active ingredient B to be dispensed is accommodated in the chamber (). The sealing film () can be destroyed or pushed away by means of a piercing member (). The piercing member () is configured to be replaceable. As a result the plastic closure () itself can be produced as standard, and the piercing member () can be produced customer-specifically for the respective application. The connection between the piercing member () and the convex membrane () preferably takes place by means of a coupling part () which is formed on the lower face of the convex membrane and on which the piercing member () having a cup-shaped coupling attachment receptacle () can be fitted.
