A package for containing and dispensing wire from a coil of welding wire. The package having an outer layer with a bottom and an outer side wall having an upper edge defining a box opening for removing the wire from the package. The package further including an inner core positioned within the inner cylindrical opening of the wire coil wherein the inner core has a base supported by the package bottom and an oppositely facing core top. The core base being generally maintained relatively to the package bottom to prevent the core from “walking-up” the wire coil and the core top being allowed to tilt as the wire exits the package.

Having thus defined the invention, the following is claimed: 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 frictionally engaging an inner surface of 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 while allowing said core to move vertically relative to said base. 2. The package according to claim 1, wherein said outer layer is a drum. 3. The package according to claim 1, wherein said outer layer is a square box wherein said at least one outer side wall is four side walls. 4. The package according to claim 3, further including an inner layer between the radially outer surface of the wire coil and said four side walls. 5. The package according to claim 4, further including corner supports between said inner layer and said outer layer. 6. The package according to claim 1, wherein said structure includes at least one upward extending protrusion fixed relative to said bottom, said structure extending above said coil bottom. 7. The package according to claim 1, wherein said structure includes at least one upward extending protrusion and a planar base sheet between said bottom of said outer layer and the coil bottom, said at least one upward extending protrusion extending from said base sheet. 8. The package according to claim 1, wherein said structure includes at least one upward extending protrusion fixed relative to said bottom. 9. The package according to claim 6, wherein said at least one upward protrusion is a plurality of protrusions spaced from said package axis to engage said inner surface of said core. 10. The package according to claim 8, further including a hold-down bar to prevent the coil from springing upwardly during the transportation of said package and a hold-down strap engageable with said hold-down bar to urge said bar downwardly, said at least one upward extending protrusion including a passage to allow said hold-down strap to extend through said core. 11. 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, 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 at least one side wall extending from a bottom edge to a top edge, said bottom edge forming a core base and said bottom being substantially open such that said bottom edge supports said core on said bottom, said package further including an upwardly extending structure fixed relative to said bottom, said structure frictionally engaging an inner surface of at least a portion of said at least one side wall of said core such that said core base is generally fixed laterally relatively to said bottom and is frictionally releasable vertically from said structure, said core top being controllably tiltable by the engagement by the wire alone as the wire exits said package. 12. A core retainer for 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, the package having an outer layer with a bottom and at least one outer side wall having a upper edge defining a box opening for removing the wire from the package, an inner core positioned within the inner cylindrical opening of the wire coil and having a core base and an oppositely facing core top with a side wall extending between said core base and said core top, said core retainer comprising at least one upward extending protrusion fixed relative to said bottom shaped to frictionally engage an inner surface of said side wall of said core near said core base and generally maintain said core base relatively to the bottom of the package while allowing said core top to be tilted by the wire as the wire exits said package.
