Abstract

A crimping tool for attaching a cap member to a container neck flange, including a nest member for axially locating the crimping tool at a predetermined position relative to the cap member; a unitary collet member mounted on the nest member for engaging and crimpingly deforming the cap member about the container neck flange; a sleeve member positioned in circumscribing relationship with the collet member in axially displaceable relationship therewith for engaging a lower portion of the collet member and urging the collet member into crimping relationship with the cap member during axial displacement of the sleeve member relative the collet member; and an axial displacement member mechanically linked to the collet member and the sleeve member for selectively axially displacing the sleeve member relative the collet member is disclosed. A method for crimping a cap member including the steps of: positioning a unitary, integrally formed collet member in circumscribing relationship about the cap member; and elastically, inwardly deforming the collet member so as to engage and crimpingly deform the cap member is also disclosed.
