Patent ID: 8613612

Claim:
A tool for forming a container from a construct, the tool comprising: a cavity for receiving a construct and the cavity having at least one sidewall for forming at least one sidewall of the container; a core operatively associated with the cavity and being operable to move into the cavity to at least partially form the construct into a three-dimensional article having at least one sidewall and a flange extending from the at least one sidewall and extending around the perimeter of the three-dimensional article; an injection cavity for receiving injection-molding material and directing injection-molding material around at least a portion of the perimeter of the three-dimensional article, the injection cavity comprising an advanced-flow section and a delayed-flow section, the advanced-flow section having a greater cross-sectional area than the delayed-flow section, and the advanced-flow section being located adjacent the at least one sidewall of the cavity, the injection cavity comprising a flange section extending across at least a portion of the advanced-flow section being operable to receive the flange of the three-dimensional article, the injection cavity extending around the perimeter of the cavity with the flange section and the advanced-flow section extending around the perimeter of the three-dimensional article; a clamping feature operatively connected to at least one of the cavity and the core, the clamping feature being for clamping a peripheral portion of the construct as the core moves into the cavity to form the construct into the container; and the clamping feature comprises a clamping ring and a draw ring for contact with the peripheral portion of the construct as the core is moved into the cavity, the clamping ring is operatively associated with one of the cavity and the core and is moveable relative to the one of the cavity and the core, the draw ring is operatively associated with the other of the cavity and the core and is movable relative to the other of the cavity and the core, the clamping ring has a clamping surface and the draw ring has a contact surface that is opposite the clamping surface, the clamping surface and the draw ring surface being positionable to hold the peripheral portion of the construct there between when the core moves into the cavity to form the container.
