Tamper evident closure

摘要

A tamper-evident closure ( 10 ) for a container ( 20 ) is provided. The closure ( 10 ) comprises a first portion ( 25 ) including inner ( 35 ) and outer ( 45 ) parts, and a second portion ( 30 ). The outer part ( 45 ) is movable relative to the inner part ( 35 ) from a first position in which the outer part ( 45 ) is immediately adjacent the second portion ( 30 ) to a second position in which there is an empty unobstructed gap (G) therebetween. The inner ( 35 ) and outer ( 45 ) parts are adapted to become irreversibly locked in the second position so that the outer part ( 45 ) cannot be moved back to the first position to close the gap (G). A combination of such a closure ( 110 ) with an in-bore filament ( 100 ) connectable to a container ( 120 ) is also provided.
