Closure to be screwed onto a container
First Claim
1. A closure to be screwed onto a container, comprising:
- a closure cap and a screw cap that can be twisted together with each other as well as relative to each other, the closure cap including a support element that is screwed to the screw cap, whereby the closure cap and the screw cap define a chamber that holds a substance and that is opened by twisting the screw cap relative to the closure cap, thereby opening up at least one passage that is in communication with the container, wherein the screw cap has a chamber wall whose free end surrounds a chamber bottom formed in the closure cap and a lid section onto which the chamber wall is formed,wherein the screw cap and the support element of the closure cap are locked by at least one thread locking mechanism configured as a spring-loaded finger located in an outer thread of the support element and that, under elastic pre-tensioning, is laid with its blocking surface against an inner thread of the screw cap such that after a few twists of the screw cap relative to the closure cap, further relative twisting of the screw cap is blocked.

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.
