United States Patent 3,150,769 WIRE FACKAGING AND HANDLING DEVICE Max Cohn, East Brunswick, N.J., assignor to South River Metal Products Co. inc, South River, N.J., a corporation of New Jersey Filed Sept. 6, 1962, Ser. No. 221,758 3 Claims. (Cl. 2tl652) The present invention relates generally to packages for items wound on reels such as wire, and specifically to a packaging and handling device for a reel of wire such that individual lengths of wire may be easily unwound without removing the reel from the device.

There are many instances wherein it is desirable to unreel lengths of wire, or other elongated elements such as rope, etc, from a reel which is mounted for rotation. It is often desirable that such a reel be portable and be contained within a packaging device for easy transportation from one location to another. One example of a situation wherein such feature would be advantageous is in the installation of television antennas wherein wire is connected, on site, between a television antenna and a television set. customarily, the wire used in these installations, 300 ohm twin-lead, is purchased in one thousand foot reels each of which weighs approximately twenty-two pounds. The wire is unwound, either by using a helper who holds the reel on a dowel such that the wire may be easily played out under the control of the helper, or by placing the reel on the ground and pulling the wire oh the reel while the reel rolls about in random fashion. Contrary to present practice, the pro vision of a container for a reel of twin-lead which could be utilized to both house the reel and to mount same for rotation supported by the container would be a significantly advantageous addition to the art.

Accordingly, it is an object of the present invention to provide a packaging and handling device for spooled material providing one or more of the aforementioned advantages. Specifically, it is desirable to provide a packaging device in which is rotatably mounted a spool for wire.

It is a further object of the present invention to provide a packaging device for a spool of wire of sufficient strength and rigidity such that the spool may be unreeled in the package and that the package will support the spool in shipping without destruction of the packaging material.

In accordance with one illustrative embodiment of the present invention, there is provided a packaging and handling device for a spool of wire which comprises a generally rectilinear box having a bottom and four side walls as well as a customary top. A U-shaped cradle is positioned within the box and is contiguous to the bottom and two of the opposing side Walls with the cradle extending approximately one-half way up each of the side walls. Reinforcing clips, generally U-shaped in cross section, are applied along the upper edge of and are supported by the cradle. Securement means for a spindle are supported by the reinforcing clips and a dowel, sized to be received Within the axial opening of a standard wire reel, is positioned on the securement means and across the box. A wire-cairying spool is positioned about the spindle for rotation. An opening may be formed in one of the side walls of the box for the exit of the Wire as it is unreeled from the spool and a second opening may be formed adjacent the first opening as an anchor for the end of the wire.

The above brief descrpition, as well as further objects, features and advantages of the present invention, will be best appreciated by reference to the following detailed description of a presently preferred embodiment ice when taken in conjunction with the accompanying drawings wherein:

FIG. 1 is a perspective view of the packaging and handling device according to the present invention;

FIG. 2 is an exploded view of the several elements combining to form a packaging device of FIG. l;

FIG. 3 is a sectional view taken along the line 33 of FIG. 1 and looking in the direction of the arrows;

FIG. 4 is a sectional view taken along the line 4-4 of FIG. 1 and looking in the direction of the arrows; and

FIG. 5 is an enlarged sectional view illustrating the construction of the reinforcing members and their engagement with the spindle and the wire reel.

Referring now specifically to the drawings, there is shown a packaging and handling device, generally designated by the numeral 10, which is adapted to receive a reel of wound material such as wire and to package same for purposes of shipping and storage and to further provide means to rotatably mount the reel such that wiremay be eflicienly and selectively removed from the package. As may be seen in FIG. 2, the device 16 includes a rectilinear box 12, having

side Walls

14, 16, 18, 20, a bottom 22 and conveniently formed

top flaps

14a, 16a, 18a, 20a, extending upwardly from the respective side walls. The

top flaps

14a, 16a, 18a, 20a are provided with interengaging hooking means, illustrated best in FIGS. 1, 3 and 4 to provide both a closure for the box 12 and a carrying handle therefor in accordance with box constructions as presently known.

A reel-supporting cradle 24 is provided within the box 12 which may be conveniently constructed of a cardboard box material. The cradle 24 is generally U-shaped or channel-shaped and has a bottom 26 and a pair of

opposed sides

28, 30 which terminate at

upper edges

32, 34 respectively. The

upper edges

32, 34 comprise fold lines within the board material of the U-shaped channel, which fold lines form the two-ply portions of the

side walls

28, 30. It will be seen that the cradle 24 is proportioned to cooperate with the box 12 with the bottom 26 being complementary to the bottom 22 of the box 14 and the

side walls

28, 36 being equal in width to the sides 16, 2d of the box 24 and being approximately one-half the height of those side walls.

A pair of reinforcing clips or channels, generally designated by the numeral 36, are positioned on and about the

upper edges

32, 34 of the

side walls

28, 30. The reinforcing clips 36 are generally U-shaped in cross section (see FIG. 5) with an edge-contacting big-ht portion 40 and a pair of parallel opposed side-contacting

walls

42, 44 adapted to contact the outer and inner faces respectively of the side walls 23, 30 of the cradle 24. The reinforcing member 36 may be conveniently formed of a sheet metal material.

Spindle securement means, best seen in FIGS. 2 and 5, are provided on the reinforcing clips 36. In the illustrative embodiment described herein the spindle securement means include integrally formed collars 46 on the inside-facing wall 44 of the reinforcing clips 36. A spool-supporting spindle 48, of a diameter complementary to the collar 46, is positioned between the opposed reinforcing clips 36 and within the collars 46 to provide rotatable mounting means for a spool of wire. As shown in FIG. 2, a standard wire spool, generally designated by the numeral 50, is provided with a hollow spindle 52 and a pair of disc-shaped end walls 54. Customarily, metallic end caps 56 are provided at the ends of the hub 52 which caps are formed with spindle-receiving openings 58. It will be appreciated that the sizes of the spindle 48 is selected such that it is slightly smaller than the openings 53 in the spool 50 such that free and easy rotation of the spool may be effected. A pair of tacking nails 60 may be provided to extend through holes 62 formed in the reinforcement strips 36 to engage to spindle 48 to secure its placement Within the mounting collars 46.

The features and advantages of the invention will be understood by considering the following description of the assembly of a spool of wire into the packaging device it and its subsequent use. A spool of wire, such as the reel 50, provided with a full load of Wire designated by the letter W, is placed within the cradle 24 by the insertion of a spindle 48 through the openings provided along the axis of the spool. The protruding ends of the spindle are then secured within the mounting collars 46 of the reinforcement clips 36 by simply spreading apart the

opposing walls

28, 30 of the cradle 24 and then returning them to parallel configuration. The entire assembled cradle 24 and spool 5% is then placed within the box 14 as shown in sectional view in FIGS. 3 and 4. The wire W may be played outwardly from the reel 50 through a wire opening 60 formed in the face 14 of the box 12. A second wire securement opening 62 may similarly be formed adjacent the opening 60 such that the wire may be folded around and tucked back into the box through the opening 62 as shown in phantom in PEG. 4 to prevent unwinding of the wire W.

Although the constructions described herein are formed of cardboard, a packaging and handling device for spools of wound material may be similarly constructed of a more durable and permanentinatcrial such as plastic, fiberboard, wood or any other well known construction material. The cradle 24 may be more permanently secured within the box 24 simply by an adhesive element or alternatively the cradle 24- forming a support for the clip 36 may be constructed as an integral part of the container.

Although the above description is restricted to one presently preferred embodiment of the invention, a large variety of alternate constructions may be employed without departing from the scope of the invention. Therefore, the following claims should be interpreted broadly in a manner consistent with the spirit and scope of the invention.
