Abstract (en)
The tetrahedron-form packing bag (10) consists of a flexible film material (32) which in the region of a corner (18) of the bag forms a tubular-form spout section (20) extending from the bag and sealed on its free end. The spout section conically tapers in the pouring direction pointing away from the corner of the tetrahedron. The spout section has at least one tear groove extending at right angles to the pouring direction. . An independent claim is included for a method for the manufacture of a tetrahedron-form packing bag from a flexible film material.
