ABSTRACT:
A flexible intermediate bulk container has a liner which is provided with one or more hollow suspension members for fastening the liner to an outer container in correct relative position. The suspension means members form vents for expulsion of air from the liner during and subsequent to filling with particulate bulk material. The suspension members are preferably tubular to provide vents for the interior of the liner. Such vents may be controlled by one-way valve devices.
