ABSTRACT:
In a container such as a cardboard container for packaging milk which comprises sidewalls, a bottom flap and a top flap as well as an ear to be folded down around a folding edge for forming a pouring spout the problem is encountered that, for opening the container, an outer portion of the ear has to be cut away and, after opening the container, no reclosure is possible, but the pouring spout remains open and may be a source of pollution.
In order to obviate this problem the ear of the inventive container comprises a socket member projecting from the ear at the surface thereof adjacent to the folding edge and facing a sidewall of the container, and there is an aperture provided in the facing sidewall for receiving the socket member. In this manner, the socket member forms a reclosable pouring spout of the container.
