ABSTRACT:
Disclosed herein is a tamper evident closure for a container having a cap on a spout. The inverted cap can be used as a tool for removing a twist away element. Both, the cap and the spout have conic guiding surfaces, which center the cap in respect to the spout, while it is removed towards and onto the spout. The initial opening of the tamper evident closure is therefore easier.
