Abstract
The break-open valve (1) for a container (21) comprises a break-away element (4) which can be twisted off by turning an activator (3). The valve (1) can be used for hermetically sealing a container (21) until its first opening and also for making it tamper-evident. The activator (3) is rotatably affixed to the valve head (2). The activator (3) comprises an inserted disk (16) with at least one opening (10) and a socket (5) which engages the break-away element (4). The activator (3) further comprises a membrane (17) which protects the contents within the activator (3) from contaminants entering through spout (18). The valve (1) has the advantage that it is cost efficient in its production, that it is easy to use and that it is suitable for dispensing sterile contents in more than one dose.
