ABSTRACT OF THE DISCLOSURE A four-sided container for liquids is disclosed which is made of plastic-coated cardboard and has a roof-shaped fold at its top for the purpose of forming a double-M closure. In each of the conventional triangular inwardly-folded flaps of the gabled sides of a container of this type, a sloping incision is made which extends from the upper edge of the gabled side in question to the central fold line or slightly beyond such fold line in each gabled side. These incisions result in triangular tongues which, when the closures are formed and sealed, prevent leakage of the contained liquid along the lines of closure.
