Pouring element and composite package with improved opening behaviour

A pouring element for a composite package, comprising:

• a monolithic main body with a flange, a hollow cylindrical spout, which defines a central axis, and a closure part formed in the spout, which runs substantially orthogonal to the central axis, with a weakening zone,
• a hollow cylindrical cutting element movably guided in the spout with at least one cutting tooth for severing the weakening zone to open the spout and composite package,
• a reclosable screw cap, which serves to drive the cutting element when the composite package is opened for the first time,
• wherein the main body consists of at least 92% by weight of HDPE and according to ASTM D3985 has an oxygen transmission rate between 12 and 23 ml O2/(m2*day), measured through a measuring surface which is orthogonal to the central axis and runs through the flange of the main body,
• wherein the weakening zone has less than 50% of the height of the remaining closure part measured parallel to the central axis,
• wherein the cutting tooth extends at the end facing the weakening zone in a circumferential direction in a plane orthogonal to the central axis and that the cutting element is thickened radially inwards such that it protrudes over an intermediate region in an assembled state and comes into contact therewith during an opening process, and
• wherein the main body is molded as a single component and excludes a separately applied barrier foil.
