The 3-piece screw closure system suits a 50 mm neck of a plastic container and is featured with a slit flex band providing superior tamper evidence and it brakes reliable with first opening. The integrated pull-up spout, which is the sealing element of the closure and enhanced with a marguerite flow control, is furnished with a screw cap. Breaking its the bridges and getting a handle, the pull-up spout can be pulled out, allowing a target-oriented pouring over a certain distance after opening the tear-off seal of the spout (second tamper evidence function).
