Tamper-indicating closure

Abstract

The invention relates to a closure for the pouring spout of a container, the closure comprising a closure cap (1) screwed onto the pouring spout (2) and comprising a tamper-indicating part (7) that, on unscrewing of the cap, bends away or breaks off or away when the closure cap (1) is unscrewed such that the tamper-indicating part (7) changes position relative to the closure cap (1), the outer surface of the tamper-indicating part (7) carrying information (8, 9) that is visible as long as the closure is in its unopened and intact condition and is no longer visible once the closure has been opened and the tamper-indicating part (7) has changed position.
