METHOD FOR PRODUCING A FOIL-CONTAINER, APPARATUS FOR THE IMPLEMENTATION OF THE SAID METHOD, AND A FOIL-CONTAINER PRODUCED ACCORDING TO THE SAID METHOD

摘要

7435/88 For the purpose of producing filled foil-containers adapted to stand upon their bases, container-parts having tubular parts are initially deep-drawn, in a strip of foil, on each side of a centreline running in the direction of travel, the said tubular parts running towards the edges of the foil but terminating at a distance therefrom. Thereafter, the foil-parts lying on each side of the centreline are heated and are folded up about the said centreline, which thereby becomes a fold-line to form open containers which are then sealed, at a first sealing station around their peripheries, except for the perpheries of the upwardly projecting tubular parts. The edges of the foil are then spread apart in the vicinity of the said tubular parts, through which the containers are filled. The spreading is released and the containers are sealed, in a second sealing station in such a manner as to close the peripheries of the said tubular parts also. Opening-aids are then made in the vicinity of the tubular parts thus formed and the filled containers are separated individually or into groups. An apparatus of this kind consists of a supply-station with a roll of foil a conveyor a deep-drawing station a heating station a first and second sealing station and a first and second stamping station.
