ABSTRACT:
A sealing spout and tools for inserting a spout of a flexible bag liner into fluid-tight sealing and anchoring engagement with a discharge outlet of a container and for removing the spout from the outlet. The spout has at least two seal rings, each having a pair of axially spaced and radially outwardly extending lobes for firmly frictionally engaging the container discharge outlet to provide a fluid-tight seal between the spout and outlet and to anchor the liner within the container. The tool has a shaft with a handle at one end for manual engagement to manipulate the tool within the container. A hydraulic or pneumatic drive is attached to the other end of the shaft for supplying force to insert or remove the spout. Carried by the drive is a collet for releasably engaging the spout to apply force to the spout during operation. Preferably, a brace is carried by the tool when inserting the spout for supporting the tool against an inner wall of the container to drive the spout into the container discharge outlet. To remove the spout, a rod is extended from the drive for securing the collet to the spout and bearing against the container discharge outlet to pull the spout from the outlet.
