Abstract

See full text

Described are opening means on a package for liquid. The pouring spout (3) can be formed by being torn open along a perforated line (8a, 8b) which begins at a starting point (14) below the front tip (17) and which terminates approximately in the middle of the upper end wall (6, 6'). In order to provide an air space of sufficient size above the liquid in the package, and an air entry space at the rearward end of the cut, so that the pouring jet of liquid can be accurately guided in passing over the front tip of the pouring spout, the invention provides that the perforated line (8a, 8b), in the lower triangular portion (13, 13') of the triangular flap, has a bend point (10) from which its path towards the outer, lower starting point (14) is directed markedly more sharply towards the bottom, and that a continuous cut line is provided in the starting point (14).
