Definitions

  • This invention relates to a package of coiled wire or the like.
  • the invention relates to an annular coil package having outer and inner peripheral covers both ends of which are locked to corresponding annular package sides to form a sealed enclosure.
  • reel sides are frequently damaged due to rough handling in shipment, and straightening operations are required in order to re-use the reel which additionally adds to the cost of handling wire in the manner related.
  • reels heretofore employed for shipping coiled wire do not in themselves constitute a protective sealed package, so that if it is desired to protect the wire against corrosion the reels must be packaged in sealed containers.
  • An important object of this invention is to provide a novel coiled wire package or the like avoiding the aforementioned and other disadvantages of presently known construction.
  • a coiled wire package comprising a spool or reel having integral hub and reel sides fabricated of relatively light gauge and inexpensive sheet material with the wire of the coil being wrapped in successive layers about the hub and between the reel sides, and on which the outer peripheral cover is secured to the outer peripheral edges of the reel sides to provide an integrated package in the form of an annulus with the several components assembled as described providing a structurally strong package.
  • Another object of my invention is to provide a package as described which is relatively inexpensive so as to permit its disposal by a customer after its contents have been expended.
  • a further object of the invention is to provide a con package which is unusually light in weight so as to facilitate handling and reduce shipping costs.
  • Still another object of the invention is to provide a coiled wire package which not only permits unwinding of the wire from its outer periphery as from a reel, but also permits withdrawal of the wire from the interior of the coil.
  • Another object of the present invention is to provide a compact, structurally sound package of coiled wire which can be assembled on a winding machine with a minimum of time and expense.
