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, preferably 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 tools have a collet carried by a shaft for releasably engaging the spout to apply force to the spout during operation of the tools. In one form the tools are actuated by a hydraulic or pneumatic drive and in another form the tools are manually actuated by pivotally moving a lever arm.

For a bulk container having sidewalls, end walls and a discharge outlet tube, and wherein a flexible bag liner having a self supporting spout with a tubular neck telescopically receivable in the outlet tube may be received, a tool for inserting the spout into the discharge outlet comprising: (a) a carrier shaft, (b) a collet at one end of the carrier shaft for engaging and releasably retaining the spout thereon, said collet extending generally axially of the carrier shaft, said collet having at least two resilient fingers telescopically insertable into the tubular neck of the spout to releasably retain the spout on the collet, (c) a lever arm pivotally connected adjacent one end to the carrier shaft adjacent the other end of the carrier shaft, (d) a fulcrum arm spaced from the pivotal connection, fixed to the lever arm, extending generally transversely to the longitudinal axis of the lever arm and having a free end constructed to bear on a wall of the container, (e) the lever and fulcrum arms being constructed so that when the tool is disposed in operative position in the bulk container the lever arm extends generally transversely of the carrier shaft when the free end of the fulcrum arm bears on a wall of the container, and (f) the carrier shaft, lever arm and fulcrum arm are constructed to move said collet generally axially relative to the container discharge outlet for inserting the spout into the discharge outlet into firm frictional engagement therewith to positively anchor and seal the liner within the container when force is applied to generally pivotally move the lever arm relative to the carrier shaft and about the free end of the fulcrum arm.
