Abstract

A tool and method for forming a container from a construct. The tool comprising a cavity for receiving a construct, a core operatively associated with the cavity and being operable to move into the cavity, an injection cavity for receiving injection-molding material and directing injection-molding material around at least a portion of the perimeter of the construct, and a clamping feature. The clamping feature is operatively connected to at least one of the cavity and the core and is for clamping a peripheral portion of the construct as the core moves into the cavity to form the construct into the container.
