ABSTRACT:
A method and apparatus for filling a flexible intermediate bulk container bag is disclosed wherein the bag is suspended clear of an underlying platform by a lift (9) urged upwards by a counterweight (11) so that during filling the bag “B” the bag falls to the underlying platform to prepare a stable base. There is also disclosed a telescopic spout (8) for delivering fill to the bag (B) and a spout closure (24) for preventing spillage of fill from the spout after filling. Hooks (10) for suspending the bag from the lift may be articulated and overlooking to allow for automation of the bag release after filling. A base (1) and tower frame (2) of the apparatus can be pivotally connected to enable the apparatus height to be reduced for transport.
