Abstract
The invention relates to a tear-open flap orifice on packs consisting of plastic-coated laminated material with a folded-round fillet-seam closure (10), there being in a first seam region (14) at least one full cut and in a second seam region (15) at least one weakening line in the form of a half cut which extends beyond the second seam region into the region of the first pack surface in contact with the filling material of the pack. As a result of an appropriate arrangement of the full cuts and half cuts, an easy-to-handle tear-open flap orifice is obtained by simple means for the entire range from drinking-straw, pour-out, drinking and spoon orifices to separating-strip orifices on freeze packs.
