Tamper evident closure system for bottles

摘要

The present invention relates to a tamper evident closure system (10) for bottles. The closure system (10) comprises an indicator ring (14) which is fixedly attached to a pourer (15) and which becomes visible, upon first opening of the cap member (40), from a gap (16) formed in between an upper (30) and a lower sleeve (31). The indicator ring (14) is not part of the cap member (40) and the necessity for forming breakable bridges in between the cap (40) and the ring (14) is eliminated. The time required for forming breakable bridges is no longer spent and formation of plastic particulates among the bridges is avoided. A method for formation of an indicator ring (14) is also disclosed.
