ATTORNEYS United States Patent 3,406,817 PACKAGE FOR STRAND MATERIAL Harrison R. Lane and Donavon L. Feaster, Fort Wayne,

Ind., assignors, by mesne assignments, to Universal American Corporation, New York, N.Y., a corporation of Delaware Filed Aug. 12, 1966, Ser. No. 572,015 8 Claims. (Cl. 206-52) ABSTRACT OF THE DISCLOSURE A storing, shipping and dispensing package for strand material, such as wire, comprising an integrally molded annular container having an open end and a closed end with spaced coaxial inner and outer walls which diverge from the closed end to define an annular strand-receiving cavity therewith and forming a central opening. An inwardly extending annular flange portion is formedon the inner wall adjacent the open end thereof. A handle member extends radially across and is integrally joined to the inner wall adjacent its open end, An annular cover member is provided for removably closing the open end of the container and having a central aperture communicating with the central opening of the container. The cover member has snap fastening means formed on its inner peripheral edge for engaging the flange on the inner wallv This invention relates generally to packages for storing, shipping and dispensing strand material, such as Wire, cable, rope, twine and the like.

In the past, wire, particularly magnet wire of the type employed for forming the windings of electrical apparatus, such as motors, transformers and the like, has initially been Wound on, shipped on and dispensed from conventional reels or spools. The use of such reels not only involved difliculty in shipment, but more particularly necessitated the use of complicated and costly de-reeling and braking apparatus for dispensing the wire from the reel. Such reels were also relatively expensive, thus dictating return of the empty reels to the wire manufacturer for reuse, the shipping cost of returning empty reels adding appreciably to the overall cost of the wire.

In an eiiort to overcome the difiiculty and expense involved in the shipment and dispensing of wire from conventional reels, non-returnable wire shipping and dispensing packages have been employed wherein the wire is loosely coiled in a cylindrical container about a central hub or core secured to the bottom of the container. Such a package not only must have a sufiiciently low initial cost that the overall economics does not require return of the empty package, but also must be sufficiently strong to protect the wire during storage and shipment and to permit lifting and handling during shipment preparatory to dispensing of the wire therefrom. It is further desirable to provide for nesting of empty packages for initial shipment and storage, thereby reducing shipping costs and storage space.

It is accordingly an object of the invention to provide an improved storing, shipping and dispensing package for strand material.

Another object of the invention is to provide an improved package suitable for storing and shipping wire in loosely coiled form and for dispensing the wire therefrom.

A further object of the invention is to provide a nonreturnable wire package which nevertheless is sufficiently strong to protect the wire therein and to permit lifting and handling during shipment and use.

A still further object of the invention is to provide an improved storing, shipping and dispensing package for Patented Oct. 22, 1968 ice strand material which when empty can be nested with similar empty packages.

Yet another object of the invention is to provide an improved storing, shipping and dispensing package for strand material in which the quantity of the material remaining in the package can readily be observed during the filling, inventory and dispensing of the material.

The improved storing, shipping and dispensing package of the invention, in its broader aspects, comprises a bottom wall having an outer peripheral edge and an inner peripheral edge which defines a central aperture. An inner wall is provided having top and bottom ends, the inner wall having its bottom end joined to the inner edge of the bottom wall and thus bounding a central opening extending upwardly from the aperture in the bottom wall. An outer wall is provided spaced from and surrounding the inner wail and having top and bottom ends, the outer wall having its bottom end joined to the outer edge of the bottom wall and defining therewith and with the inner wall a strand-receiving cavity which is open at its upper end and which surrounds the central opening. The preferred embodiment of the invention is integrally molded of plastic material and has an annular configuration with the inner and outer walls divergently tapering upwardly from the bottom wall.

The above-mentioned and other features and objects of this invention and the manner of attaining them will become more apparent and the invention itself will be best understood by reference to the following description of an embodiment of the invention taken in conjunction with the accompanying drawings, wherein:

FIG. 1 is a top view in perspective of the improved storing, shipping and dispensing package of the invention intended for use with magnet wire and showing the cover removed;

FIG. 2 is a bottom view in perspective of the package of FIG. 1;

FIG. 3 is a side cross-sectional view of the improved package of the invention with the cover in place;

FIG. 4 is a top view of the package with the cover removed, taken generally along the line 44 of FIG. 3;

FIG. 5 is a top view of the cover member of the package of FIG. 3;

FIG. 6 is a fragmentary cross-sectional view taken generally along the line 6-6 of FIG. 5; and

FIG. 7 is a fragmentary cross-sectional view taken generally along the line 77 of FIG. 5.

Referring now to the figures of the drawing, a specific embodiment of the improved package of the invention, particularly intended for storing, shipping and dispensing magnet wire, is shown, the package generally comprising an annular container 10 and an annular cover member 12. The container 10 comprises an annular relatively thin bottom wall 14 and relatively thin inner and outer walls 16, 18. The bottom wall 14 has inner and outer peripheral edges 20, 22, the inner peripheral edge thus defining a central circular aperture 24. The inner wall 16 has top and bottom ends 26, 28 and is circular in cross-section, the bottom end 28 being joined to the inner edge 20 of the bottom wall 14 thus defining a central opening which extends upwardly from the aperture 24 defined by the inner edge 20 of the bottom wall 14. Inner wall 16 tapers inwardly and upwardly from the bottom wall 14 toward its upper end 26, thereby giving the central opening 30 a frusto-conical configuration.

The outer wall 18 likewise has top and bottom ends 32, 34 and is circular in cross-section, the bottom end 34 being joined to the outer peripheral edge 22 of the bottom wall 14. Outer wall 18 thus coaxially surrounds inner Wall 16, being radially spaced therefrom so as to define with the bottom wall 14 an annular cavity 36 which is open at its upper end 38. The outer wall 18 tapers outwardly and upwardly from the bottom wall 14 toward its upper end 32 so that the annular cavity 36 is larger than its upper open end 38 than at the bottom wall 14, the taper of the inner and outer walls 16, 18 being such that the radial width between the outer surfaces of the inner and outer walls 16, 18 adjacent the bottom wall 14 is less than the radial width of the opening 36 and its upper open end 38, thus permitting nesting of one empty container within another empty container.

As best seen in FIG. 3, wire or any other elongated strand material may be loosely coiled in the annular cavity 36 through the open upper end 38, as at 40. After storage and/or shipment of the package which has been filled to the desired level with the loosely coiled wire or other strand material 40, the material can then be dispensed from the container 10 through the open upper end 38 of the annular cavity 36.

In order to provide for the lifting of the package with the wire therein, a handle member 42 is provided extending transversely across the central opening 30 and joined to the inner surface of the inner wall 16 adjacent its upper end 26. Handle member 42 is generally U-shaped in cross-section, having a bottom section 44 and parallel side sections 46, 48.

Annular flange portions 50, 52 are respectively formed on the inner wall 16 at its upper end 26 and extend radially inwardly therefrom, annular flange portion 50 extending between the opposite extremities of the side section 46 of the handle member 42 and annular flange portion 52 likewise extending between the opposite ex= tremities of the side section 48. A plurality of radially spaced-apart reinforcing ribs are formed on the inner surface of the side wall 16 tapering downwardly from the annular flange portions 50, 52. A plurality of radially spaced-apart ribs 56 are formed on the outer surface of the outer wall 18, respectively terminating in downwardly facing shoulders 58 which are spaced upwardly from the bottom wall 14, as best seen in FIG. 3. Shoulders 58 on the outer ribs 56 serve as stops during nesting or stacking of a plurality of the containers, thereby to prevent the containers from being too tightly nested together.

The entire container 10 including the bottom 14 and the inner and outer walls 16, 18 including the handle member 42, flange portions 50, 52, and the ribs 54, 56, is preferably integrally molded from suitable plastic material. In a specific embodiment of the invention, the container 10 is injection molded of high density linear polyethylene or polystyrene. These plastic materials are sufliciently rigid and possess sufiicient strength not only to protect the wire in the container against damage during shipment and storage, but also to permit lifting and handling of a container completely filled with wire.

In accordance with an important aspect of the invention, the container 10 may be formed of translucent or even nearly transparent plastic material thereby to permit the level of wire in the container to be observed during filling, inventory and dispensing.

The cover member 12 is likewise integrally molded from suitable plastic material, such as high density linear polyethylene or polystyrene. Cover member 12 has a flat annular top portion 60 with annular downwardly extending inner and outer flange portions 62, 64 respectively formed on its inner and outer peripheral edges. The downwardly extending annular flange portions 62, 64 have bottom edges which respectively engage flange portions 50, 52 and the upper end 32 of the outer wall 18. The outer flange 64 has a depending lip 66 which tightly fits over the upper end 32 of the outer wall 18. It will be observed that the inner flange portion 62 defines a central aperture 68 coaxial and communicating with the central opening 30 of the container 10. A plurality of radially spaced-apart reinforcing ribs 70 extend radially between the inner and outer flange portions 62, 64.

In order to removably secure the cover member 12 to the container 10, a plurality of clamping members 72 are integrally formed on the flange portion 62 and respectively have portions 74 depending therefrom. Depending portions 74 respectively have outwardly facing latching portions 76 formed thereon terminating in shoulders 78 which define notches for engaging the inner peripheral edges of the flange portions 50, 52. It will thus be seen that when the cover member 12 is assembled downwardly onto the upper end of the container 10, the latching portions 76 of the clamping members 72 will initially be cammed outwardly by the flange portions 50, 52 as the cover members move downwardly, and will then resiliently engage the inner peripheral edges of the flange portions 50, 52 in snap-on relationship. It will be observed that the clamping members 72 are disposed between the reinforcing ribs 70 of the cover member 12.

It will be readily seen that flanges 50, 52 and the cooperating clamping members 72 on the cover member 12 may be located on the outer peripheries of outer wall 18 and cover member 12, respectively, rather than on the inner peripheries, as shown; in larger sizes, it may be desirable to provide flanges and clamping members on both the inner and outer peripheries.

In order to provide for removal of the cover member 12 from the container 10, slots 82 are formed in the cover member communicating with the latching portions 76, as best seen in FIGS. 6 and 7. Slots 82 may be employed for the insertion of a tool, such as a screwdriver, manually to deflect clamping members 72 so as to disengage the flange portions 50, 52. A part-annular stacking retainer 80 is formed on the upper surface 60' of cover member 12 adjacent and radially outward from each of the clamping members 72, as seen in FIGS. 6 and 7.

In a specific embodiment of the invention, for use in storing, shipping and dispensing magnet wire, container 10 was injection molded of rigid, translucent polyethylene plastic material and had an overall outside diameter at the top of 11% inches, an outside diameter of the inner wall 16 at its top end 26 of 7 inches, an overall height of 13 inches, and a wall thickness of ap roximately .100 inch, the inner and outer walls 16, 18 being respectively tapered upwardly by 1.5". In a specific embodiment, flanges, 50, 52 define an inside diameter of 6% inches and had a thickness of inch, the reinforcing ribs 54 extending downwardly from the upper end of container 10 by 4 /2 inches and the shoulders 58 on the ribs 56 being disposed downwardly from the upper end by 5 inches. Handle 42 at its center had a width of inch and a height of /2 inch. In this specific embodiment, cover member 12 was injection molded of semi-rigid polyethylene plastic material and had an overall outside diameter of 11.586 inches and with the lip 66 having an inside diameter of l1 inches, cover member 12 having a general wall thickness of approximately .100 inch. In this specific embodiment, cover member 12 had an overall height of W inch from the bottom edge of ribs 66 to the top surface 60, lip 66 having a height of inch, and the inner flange 62 defined an inside diameter of 6 inches. In this embodiment, the clamping mem bers 72 had an overall height of one (1) inch.

It will now be readily apparent that the improved storing, shipping and dispensing package of the invention is lighter, cleaner and less expensive than prior packages, thus permitting its employment as a non-returnable package.

Furthermore, molding the package from plastic material renders it impervious and free from the corrosive effects of water and other liquids, thus protecting the wire therein, whereas prior paper and metal packages are subject to such hazards. In addition, the molded plastic package of the invention will withstand severe impacts and other rough usage, whereas prior metal packages may be permanently dented by dropping, etc. and the wire there- 1n consequently damaged, and prior paper packages are subject to puncture and moisture and likewise result in damage to the wire.

It will be observed that the lifting handle is positioned inside the container, thus eliminating the conventional external bail employed for lifting prior packages, the pro trusion of a bail requiring that prior packages be oriented on a pallet with the bails extending toward the center of the pallet. It will further be seen that the handle is protected during shipment, thus eliminating damage, and particularly that it provides no obstruction during the filling and dispensing operations, i.e. there is no bail which must be positioned out of the way of winding machinery. It will also be readily apparent that in larger sizes, the integrally molded handle may be eliminated and a separate, removable handle employed, or the package may be lifted by expandable tong arrangements engaging the inner wall.

It will be readily seen that a sleeve for filling the container or conventional cone devices used for de-reeling can readily be attached to the upper end of the container, the same filling and de-reeling devices which have heretofore been employed with prior packages being usable with the package of this invention without modification. Molding of the container 10 from translucent plastic material permits observation of the level of the wire or other strand material remaining in the container not only during filling and inventory, but also during the de-reeling operation, an extremely helpful feature to the operator. It will finally be observed that empty containers can be nested for shipment and storage, thus requiring considerably less space, and that completely filled containers can be stacked one upon the other, the inside diameter of inner wall 16 at its bottom end 28 being greater than the outside diameter of the retainers 80, retainers 80 thus, serving as centering or locating devices when one container is stacked upon another.

While the package of the invention has been illustrated and described as being integrally molded of plastic material and annular in configuration, it will be readily understood that other materials, such as metal may be employed, that it may be fabricated rather than integrally formed, and that it need not be circular in cross-section, i.e. it may be hexagonal, octagonal, or any other geometric configuration. Further, while the preferred embodiment is formed of translucent or transparent material to permit viewing the contents, the package of the invention may be formed of opaque material. Finally, while a package for wire has been described, it will be readily apparent that it is equally usable with other strand-like materials such as cable, chain, rope, twine and the like.

While there have been described above the principles of this invention in connection with specific apparatus, it is to be clearly understood that this description is made only by way of example and not as a limitation to the scope of the invention.
