ABSTRACT:
The invention relates to a continuous manufacture of packing containers comprising an outer rigid casing and an inner baglike container. The inner container is manufactured by arranging first seals in pairs at equal distances, substantially in transverse direction of the web, whereupon mandrels are introduced into the web which has been provided with seals. Opening devices are applied to the web with the help of the mandrels as backing. After the mandrels have been withdrawn the free edges of the web are sealed to one another and the contents are introduced into the tube formed. The tube is sealed in its transverse direction along narrow sealing regions to form filled and closed containers which are separated from one another and are introduced into a rigid casing.
