Abstract

With an eye towards achieving the objective of configuring and refining a closure in such a way that an available space defined by the support element is effectively utilized while the volume of the chamber is maximized, a closure to be screwed onto a container, comprises a closure cap and a screw cap that can be twisted together with each other as well as relative to each other, whereby the closure cap has a support element that can be screwed to the screw cap, whereby the closure cap and the screw cap delimit a chamber that holds a substance and that can be opened by twisting the screw cap relative to the closure cap, thereby opening up at least one passage, and whereby the screw cap has a chamber wall whose free end surrounds a chamber bottom that is formed in the closure cap, wherein the screw cap has a lid section onto which the chamber wall is formed.
