  • Patent number: 5806706
    Abstract: The invention concerns a container (100) which is made of a tubular material (111), which is meant for bulk goods, and which comprises at least an outer wall (112), a bottom portion (114) and possibly a top portion. In the interior of the container (100), a cylindrical reinforcement part (113) has been fitted, which has been fixed to the container (100) so that, at the same time, the cylindrical reinforcement part (113) forms at least a part of the bottom (114) of the container. The height (S) of the cylindrical reinforcement part (113) is by the lower portion (113a) of the cylindrical reinforcement part (113) higher than the filling height (H) of the container (100).

  • Patent number: 5544472
    Abstract: The invention concerns a method for packaging of bulk goods into a unit-load package and a unit-load package for bulk goods. The unit-load package consists of an inner package (11) and of an outer package (16). The inner package (11) is an inner sack made of a flexible material, which has been placed on a base (13) for the time of filling with bulk goods, whereby, during the filling, the inner package (11) is shaped substantially as parallelepiped. The outer package (16) is an outer package which is made of a plastic material and which surrounds the inner package (11) tightly and gives it adequate stability.

  • Patent number: 4715635
    Abstract: A flexible container for transporting and storing bulk goods, preferably arranged so as to be liftable by its upper end, is constructed from a tubular blank so as to include a shell, a bottom and a filling aperture, the pleats being formed in the shell having lower parts which are folded so as to be coplanar with the container bottom. In order to both strengthen the relatively weak region of the container bottom and to enable the manufacture of the container in an automated fashion, the tubular container blank is closed by a bottom seam located substantially in the central region of the container bottom and the upper plane of each pleat is folded into the plane of the container bottom and affixed to the lower plane of the respective pleat by a connecting seam.
