1. A capsule closure for mounting over the spout opening or on the threaded connector end of a liquid or bulk goods container for metered adding of a substance by depressing or unscrewing the cap, wherein the cap ( 1 ) encloses a receptor device ( 2 ) formed at its lid inner side, which receptor device ( 2 ) fits into the interior of a coordinated nipple part ( 3 ), further that a coordinated film-sealed container capsule ( 8 ) having sealing film ( 9 ) is latchingly engaged in the interior of the receptor device ( 2 ) with its sealing film ( 9 ) facing the lower side of the cap ( 1 ), and that in the interior of the nipple part ( 3 ) below the inserted container capsule ( 8 ) there is an annular shoulder ( 10 ) which projects radially inwards, at the inner edge ( 11 ) of which there is mounted at least one fixed or movable piercing and/or cutting element ( 12 ), and on a shoulder ( 17 ) which projects radially outwards there is supported a tamper-evident strip ( 15 ) below the lower cap edge of the attached cap ( 1 ), after the removal of which the cap ( 1 ) is movable downwards on the nipple part ( 3 ), causing the fixed or movable piercing and/or cutting element ( 12 ) to become effective and to cut the film, and that the section ( 14 ) of the nipple part ( 3 ) that lies below the shoulder ( 10 ) is configured either as a sleeve or as a flange, and wherein at the inner edge of the inwardly projecting shoulder ( 12 ) there are formed upwardly directed piercing or cutting elements ( 12 ), and on a support element ( 37 ) there is attached a pretensioning lever ( 36 ), which is pivotable vertically about the support element ( 37 ), around a horizontally lying axis, so that by depressing its rear lever ( 38 ) the pretensioning lever ( 36 ) is pivotable upwards for pretensioning the film ( 9 ) in the container capsule.
