Tamper evident security closure to access opening of a container, in particular a bottle

Abstract

A tamper evident closure for an access opening in a container has a closure part which is placeable onto the access opening in a sealing manner and has a bottom sleeve portion and an upper cover portion which are connected in one piece to each other via a first tamper evident indicator. A hood-like indicator cap forms a second tamper evident indicator and at least partially surrounds at least the cover portion of the closure part, wherein access to the first indicator is possible only when the indicator cap is destroyed. A tear off tab is formed in the indicator cap, which is bounded by two grooves which are arranged at a distance and end at a distance from the bottom rim of the indicator cap, wherein at least one of the grooves is assigned a breaking point which extends as far as the bottom rim of the indicator cap.
