Abstract

An apparatus and method for dispensing fine particle material from a container such as a flexible intermediate bulk container. The invention includes a dispensing assembly that has a dispensing device that is secured to an outlet tube of the container. Securement is achieved by a strap member wrapped about the container's outlet tube and a clamping casing and/or by an inflatable member that expands outward from the clamping casing. The casing surrounds a transport tube which is axially shiftable following securement of the clamping casing to the outlet tube. A head piece with gas cavity and radial and oblique extending ports is provided at the end of the transport tube. The dispensing device is inserted into the outlet tube below a blocking member provided at the base of the outlet tube. Following attachment of the outlet tube to the clamping casing, the blocking member is released. The transport tube is then released from a first position, shifted and then fixed in a second position. The second position places the head of the dispensing device into the main compartment of the container and above the released blocking member. At this location gas, is injected through the ports and …
