Closure for container for detecting previous opening is deformed by formation on container when first opened to identify the first opening of the closure

摘要

The container has a formation in its upper region that interacts with an interaction arrangement provided on the closure so that the formation causes an irreversible deformation of the closure after its first opening to identify the first opening of the closure. An independent claim is also included for a container with a formation in its upper region for use with an inventive device.
