Abstract
Abstract A bulk package having a bundle of closely packed soldering and brazing split rings tightly sheathed in plastic material removable portionwise by hand enabling individual rings to be freed from the bundle for use. No adhesive of any kind is needed to keep the rings together or to hold the sheathing material to the bundle.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
149 words
A method of bulk packaging a plurality of annular metal pieces used for soldering or brazing which includes the steps of forming a wire strip into a closely wound helix, supporting the helix on a cylindrical metal rod and longitudinally cutting through one side of the helix to form a bundle of closely packed split rings pieces stacked in side-by-side relationship, placing a length of tubular nonadhesive heat-shrinkable plastic sheathing, having internal diameter greater than the external diameter of the pieces, over the outside of and along the length of the bundle to envelop all of the pieces, heat shrinking the plastic sheathing onto the bundle and onto the entire surface of the rings by application of a hot air blast to form an integral, relatively rigid tubular package of closely packed and separable pieces within a manually removable sheath of said plastic material, and removing the supporting rod.
Claim 2
Independent Claim
149 words

Claim 3
Dependent Claim
49 words
The method defined in claim 1 which includes the further steps of supporting annularly shaped split ring soldering rings, in closely packed relationship, and coating the pieces so supported with a sheathing of a nonadhesive and nonhardening plastic material which remains readily removable by hand during storage and transit.
Claim 4
Dependent Claim
48 words
The method defined in claim 1 which includes the further step of providing at one end of the package an overhang of covering or sheathing material to facilitate gripping and peeling away of the manually removable plastic sheathing from the pieces to free individual pieces from the package.
Claim 5
Dependent Claim
32 words
The method defined in claim 2 which includes the further step of providing the plastic sheath with at least one row of perforations extending longitudinally along the entire length of the sheath.
