Abstract
A pack for flowable contents, such as liquids, has tubular side walls, a bottom and a top wall, and is formed of a deep-drawable plastics material. The top includes a vertically upstanding, externally threaded collar and defines a pouring opening which is closable by a threaded top. The pack is formed by two half shells, and a seam passes around the pack in a longitudinal plane and extends nearly to the top free upper edge of the collar. The seam is interrupted in the top by the pouring opening and projects outwardly from diametrically opposite sides of the pack. According to a method for forming the pack of the invention, the collar is formed by two collar halves which are joined together at the seam. Threads are formed on the collar and the upper free edge includes an annular sealing surface for a correspondingly formed screw top.
