Retainer ring for welding wire container disclosure

A retainer ring adapted for use with a container of low twist welding wire, said retainer ring comprising:

• a generally flat outer portion with an outer periphery and an inner periphery, an innermost wire extraction opening having a center and a bell mouthed portion, said bell mouthed portion having an interior and an exterior side, said inter side including a continuous convex surface between said inner periphery and said extraction opening, said retainer ring containing a number of projecting lobe portions disposed in said flat outer portion, each said lobe portion defined by the intersection of two arcs, each arc having a given radius and having a center of each said radius offset from said center of said extraction opening, whereby said outer periphery contains alternate areas closer to and farther from said inner periphery.

A container of low twist welding wire, said container comprising a cylindrical outer wall having a set diameter, a lower partition and an upper opening and adapted to contain and allow controlled pay ut of a multitude of convolutions of welding wire formed into layers defining a hollow, cylindrical spool, said wire having an inner cylindrical surface defining a central cavity in said spool and having a selected diameter, said container further including a retainer ring for resting on said spool, said retainer ring comprising a generally flat outer portion with an inner diameter and an outer periphery for fitting into said set diameter of said outer wall, an innermost wire extraction opening and an inner curved portion between said inner diameter and said innermost wire extraction opening, said inner curved portion gradually curving upward from said inner diameter of said flat portion to said wire extraction opening.

A retainer ring for a container of low twist welding wire comprising:

• a generally flat outer portion with an inner diameter and an outer periphery, an innermost extraction opening having a center, lobe portions defined by said outer periphery, said outer periphery formed by intersecting arcs each having a given radius with a center offset from said center of said extraction opening, said lobe portions generally disposed in said flat outer portion and an inner bell mouthed portion between said innermost wire extraction opening and said inner diameter, said bell mouthed portion curving upwardly from said flat outer portion to said wire extraction opening in accordance with a selected radius, said bell mouthed portion having an interior and an exterior side, said interior side including a continuous convex surface between said inner diameter and said extraction opening, said extraction opening having a diameter substantially smaller than said inner diameter of said flat portion.

A retainer ring for a container of low twist welding wire, said retainer ring comprising:

• an outer portion with an outer periphery and an inner periphery, said outer portion containing a number of projecting lobe portions whereby said outer periphery contains alternate areas closer to and farther from said inner periphery and an inner bell mouthed portion defining an innermost wire extraction opening having a center, said inner bell mouthed portion having an interior and an exterior side, said interior side including a continuous convex surface between said inner periphery and said extraction opening.

A container of low twist welding wire, said container including a cylindrical outer wall having a set diameter, a lower partition and an upper opening and containing and allow controlled pay out of a multitude of convolutions of welding wire, said welding wire formed into layers defining a hollow, cylindrical spool of said welding wire within said container where said spool has an outer cylindrical surface engaging said cylindrical outer wall of said container and an inner cylindrical surface defining a central cavity in said spool and having a selected diameter, a vertically movable retainer member loosely disposed within said container on top of said spool of welding wire, said retainer member comprising a generally flat outer portion with a outer periphery fitting into said set diameter of said outer wall and containing a number of projecting lobe portions whereby said outer periphery contains alternate areas closer to and farther from said outer wall when said retainer member is resting on said hollow, cylindrical spool of welding wire in said container and an inner bell mouthed portion defining an innermost wire extraction opening with a diameter substantially smaller than said selected diameter of said spool.
