A cap arranged to interact with a spout has a top portion, a sidewall portion (104) depending from the top portion and formed in one piece therewith. The sidewall portion (104) has an interior threading arranged to interact with exterior threading of the neck during an opening operation and during a closing operation. The cap further has cutting elements (112) with a first end hingedly attached to the sidewall portion and a free end portion arranged to interact with a membrane portion of the spout. The hinged attachment allows for the cutting element to pivot in an axial direction. Further, the free end portion has a blunt tip (112B) and a comparatively sharper cutting edge (112A) on a lateral side of the free end portion for cutting the membrane portion when unscrewing the cap.
