Abstract

Closure ( 1 ) for a container, in particular for pourable or flowable products, has a closure head ( 2 ), a circumferential face ( 3 ) which is connected at least partially to the closure head ( 2 ), and means ( 6 ) which interact with the container in such a way that the discharge opening of the container can be closed by the closure ( 1 ), with the result that the closure ( 1 ) has means ( 4 ) for fixing a plurality of portion containers ( 7 ) of in each case less than 50 ml filling volume to the closure ( 1 ). The portion containers ( 7 ) are filled with at least one additive, such as fragrances, dyes or surfactants, that can be mixed selectively with the pourable or flowable product located in the container.
