Abstract
A pouring closure includes a flange for welding onto a combipack or to the foil material of a container sealed with the foil material, along with an upwardly projecting circular rim thereon and a rotatable combined lid and pouring nozzle that can be clipped onto the upwardly projecting circular rim, which forms a piercing edge arrangement. This piercing edge arrangement includes a part of a cap lid, which can be opened from the lid surface around a swinging axis. Two piercing cutters are on the lower side of this part of the cap lid behind its swinging axis and near the edge of the cap rim and are able to be folded up beyond a level of the lower side of the flange and to pierce the combipack or the membrane liner running below the flange. Thereafter, the lid and pouring nozzle is rotated on the flange rim, so that the two piercing cutters cut-out a disc, of approximately 360°, from the combipack or the membrane liner after the folding upwards movement.
