Abstract: The present invention includes of a method for producing a cross sectionally tetragonal tube package for flowable substances, in particular milk and juices. A carrier material (12) coated with synthetic plastic is cut longitudinally and horizontally through to center (35) and then shaped to form two welds (13,14) which made up the relevant tube (1) of the package. The stepped edge (10) of each web (13,14) serves as the top-end edge (10,16) of the tube (1), the blank (I) of which is separated form the web (13,14) by (at 41) parting it in transverse relationship to their direction of movement (15), the blank being provided with a longitudinal sealing seam for formation of the tube. At the top end of the tube (1), there are formed extensions of oppositely disposed side walls (3,5) and projecting wall panels (8,9) which are folded over into the surface of the top (7), the top (7) being integrally moulded on the free edge (10) of the wall panel ( 8,9) and the adjacent stepped end edge (10).

Abstract: A method of producing a package for fluids made of a synthetic plastic material, in which a strip of the material is shaped to form two rows of tub-shaped containers which are filled, sealed, pairs of them being folded together to form a single container, and welded closed into a single container.In a particular preferred embodiment, two plastic webs are first brought together continuously and sealed along outer edges, to form a tube, with the tube then being filled from above, with thereafter transverse seals provided between pairs of adjoining tub-shaped containers.

Abstract: The prerequisites for the injection moulding from thermoplastic material of container lids with a tear-up opening arrangement which is to function well on opening as well as on reclosing are improved through the use of a modified thermoplastic containing inert filler in a quantity of 10-15% of the weight of the mixture. Such a modified thermoplastic is manufactured by heating a thermoplastic, known in itself, e.g. polyethylene, to melting temperature with simultaneous admixture of the filler. The mixture is mechanically processed for a good distribution of the filler in the melted plastic mass which thereafter is cooled to form the modified thermoplastics.

Abstract: A cardboard/plastics film laminate package (1) is provided with an opening arrangement consisting of a channel (6) fixed to the top wall of the package over an opening area (4) bounded by a tearing line (3) part thickness perforations and an opening element (9). The opening element (9) is a strip having a pull-tab (10) at one end and a bent back penetrating portion (11) fixed at (14) to a part (14") of the opening area. On pulling the tab (10), the penetrating portion (11) wedges between the channel (6) and the opening area of the package and is forced to penetrate the opening area. On further pulling, the opening area of the package is torn away and removed through the channel (1) which then forms a pouring mouth.
