Abstract:
1. A package for containing and dispensing wire from a coil of welding wire, the coil having a coil axis parallel to a package axis, a coil top transverse to the coil axis and an opposite coil bottom, the wire coil further including radially inner and outer surfaces parallel to the coil axis, the inner surface defining an inner cylindrical opening coaxial with the coil axis having an opening diameter, said package comprising an outer layer having a bottom and at least one outer side wall having a upper edge defining a box opening for removing the wire from said package, said package further including an inner core positioned within the inner cylindrical opening of the wire coil, said inner core having a core base supported by said bottom and an oppositely facing core top, said inner core further including an outer diameter coaxial with said coil axis when at rest and said core outer diameter being less than said opening diameter such that said package further includes a gap between said inner core and said wire coil thereby allowing relative motion of said inner core relative to said coil, said package further including a structure at least near said bottom of said package, said structure being fixed relative to said bottom and engaging said inner core such that said structure substantially prevents lateral movement of said core base during the unwinding of the wire while allowing said core top to be controllably tilted by the engagement of the wire alone as the wire exits said package, and a planar base sheet between said bottom of said outer layer and the coil bottom, said structure being secured to said base sheet.
