ABSTRACT:
A method and apparatus for manufacturing a pack for flowable contents in a deep draw process having tubular side walls, a bottom and a top. The top has a pouring opening having an upstanding collar and a seam that passes around the pack in a plane that is oriented in the top so that the plane is interrupted by the pouring opening and projects on diametrically oppositely disposed sides almost as far as a free upper edge of the collar. The collar is formed of two collar halves joined together at the seam, and threads are provided on the collar for a screw top. An annular fitting sealing surface is provided on the free upper edge of the collar
