Abstract: A cap and neck assembly for closing an upper end of a package (10) is provided. The neck (20) is formed by a tubular member (110) being provided with external threads (22), and an upper tubular portion (120) extending from the tubular member (110) and being releasably attached to a membrane (150) closing an upper end of said upper portion (120). The cap has a lower portion the threads (22) of the neck (20), and an upper portion (33) being provided with at least one cutting element (50) configured to separate the membrane (150) from the neck (20). When the cap (30) is threaded onto the neck (20) to its axial end position for the first time prior to separating the membrane (150) from the neck (20), the axial distance between a cutting edge (54) of the cutting element (50) and the membrane flange (170) is less than 1 mm.

Abstract: Disclosed herein is a cap configured to interact with a neck. In some embodiments, the cap comprises an inner wall portion and at least one cutting element projecting radially inwards from the inner wall portion. In some embodiments, the cutting element has a hinge portion connected to the inner wall portion, and a cutting portion extending radially inwards from the hinge portion, wherein a first axial thickness of the hinge portion is between 35 and 80% of a second axial thickness of the cutting portion. Also disclosed herein is an assembly comprising the cap and a spout having a membrane closing a tubular member of the spout.

Abstract: A cap arranged to interact with a spout has a top portion, a sidewall portion depending from the top portion and formed in one piece therewith. The sidewall portion 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 a tamper evidence, which is removably attached to the sidewall portion having cutting elements 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 and a comparatively sharper cutting edge on a lateral side of the free end portion.
