REEL SUPPORTING STRUCTURE Original Filed July 25, 1962 FIG. 2

INVENTORS BERTIL E. JOHNSON LINSLEY S. GRAY ATTORNEYS United States Patent 3,233,728 REEL SUPIGRTIlJ G STRUETIURE Bertil E. Johnson, Richiield, Mind, and Linsley S. Gray,

Aurora, Ill., assignors to Minnesota Mining 8: Mannfacturing Company, St. Paul, Minot, a corporation of Delaware Continuation of application Ser. No. 212,257, July 25, 1962. This application Sept. 23, 1964, Ser. No. 401,287

3 Claims. (Cl. 20652) This application is a continuation of our copending application, Serial No. 212,257, filed July 25, 1962.

This invention relates generally to a shipping and storage carton for reels and the like (upon which, for example, magnetic tape is wound) and more particularly to means for supporting said reel within said carton.

Previously known supporting devices for reels when shipping or storing the same allow movement of said reelsrelative to the storage cartons. Also, the previously known devices have not been able to withstand the shock and stress put thereon by the reel when the carton is being shipped. or when the carton is dropped from the hands of. the handler. Movement of the reels relative to the cartons has in the past caused a dust to form due to abrasion between the reel flanges and the carton which has a deleterious eifect upon the magnetic tape or the like wound upon the reel. Also droppage of the carton causes the flanges in the reel to become damaged and no longer useable when an adequate support for the reel is not provided.

It is therefore an object of the present invention to provide means for s pporting said reels within a shipping carton and/or storage container which will not allow movement of the reel relative thereto or displacement of the reel when placed in said carton.

It is a further object of the present invention to provide a new carton for shipping and storing reels of magnectic tape or the like.

The above and further objects and novel features of the present invention will appear from the following detailed description when the same is read in conjunction with the accompanying drawings, wherein:

FIGURE 1 is a perspective view of the several parts of the present invention shown in disassembled relation and shown with a reel to be supported thereby;

FIGURE 2 is a partial elevation view taken substantially along the lines 2-2 of FIGURE 1; and

FIGURE 3 is a perspective view showing the component parts of the present invention in partially assembled relation.

Referring now to the drawings, and particularly to FIGURE 1 thereof, there is shown several parts of the supporting device, made in accordance with the present invention, in disassembled relation. The several parts comprise a male plug 4, a supporting member or file 5, and a female plug 6 adapted to be press-fitted on said male plug 4 to form a. reel supporting core. A reel 7 of the type adapted to be supported by said core is also illustrated in FIGURE 1.

The male plug 4 is formed with a cylindrical wall portion 9 and an end wall or plate 10 forming a tubular member having one closed end and an opposite open end. The open end of the cylindrical wall portion 9 is encircled by a radially outwardly extending flange 11 formed integrally with. said cylindrical wall portion 9. The plugs 4 and 6 are preferably formed by stamping thin sheet material such as tin plate or other easily deformable material.

The reel supporting member is formed of a single sheet of corrugated fiberboard or similar material scored twice so as to fold upon itself as shown by the lines 12 and 13. The folding of the sheet provides two opposing panels 14 and 15 joined by an end wall 16 having a width substantially the same as the width of the reel to be supported by said member 5. The member 5 thus takes the shape or a loose-leaf binder or file forming a combination unit for a sleeve or box-like shell 34, see FIGURE 3. The panel 15 of the member 5 is provided with a generally centrally located opening 17 therein, 'having a diameter substantially equal to the outer diainetrical dimension of the cylindrical wall member 9 of the male plug 4.

The female plug 6 comprises a cylindrical wall portion 18 having axially extending, radially outwardly projecting semicylindrical ribs or protuberances I9, 20 and 21. The protuberances I9, 2% and 21 are equally and circumferentially spaced about the periphery of the wall portion 18 and extend the length of said portion. The female plug is formed with one end wall 22 enclosing said cylindrical wall portion and one end of said protuberances. As shown in the drawings, the endwall is provided with a small opening 23 for purposes to be hereinafter described. The opposite end of the cylindrical wall portion 18 is open and is formed with a substantially radially outwardly projecting flange 24 encircling the open end of said Wall portion and the protuberances 19, 2t) and 21.. The flange 24 is notched as at 24a in the area adjacent each of the protuberances 19, 2t and 21. The notches 24a remove substantially all of the flange member adjacent the pro t'uberances 19, 2t and 21 but leave small lip areas 25 encircling said protuberances.

The inside diametrical dimension of the cylindrical wall portion 18 of the female plug 6 is slightly smaller than the outside diametrical dimension of the cylindrical Wall portion 9 of the male plug 1. As an illustrative example, if the tin plate from which the female plug is formed has a thickness of 0.014 inch the inside diametrical dimension may be .020 to .028 inch smaller than the outside diametrical dimension of the cylindrical wall portion 9 of the male plug 4.

The reel 7 illustrated in FIGURE 1 is adapted to support magnetic tape or the like 26 and comprises a pair of flanges 27 and 28 secured to a hub 29. The hub 29 is formed with an enlargedcentral opening 33 and axially extending grooves 31, 32 and 33, adapted to fit over the driving spindle of a magnetic recorder and/ or reproducer (not shown). t

In assembling the several parts shown in FIGURE 1, the cylindrical Wall member 9 of the male plug 4 is inserted through the opening 17 in the panel 15 to bring the flange portion 11 thereof substantially flush with one surface of said panel 15. The female plug is then carried into position axially aligned with the cylindrical wall member 9 of the male plug 4, so that said cylindrical wall portion 9 may be press-fitted within the cylindrical wall member 18 of the female plug. The plugs are pressed together to a position such that the end wall 10 of the male plug 2 is brought toward and in many instances may even be juxtapositioned against the end wall 22 of the female plug 6. The press-fit is accomplished by a suitable press and jig (not shown) which presses against the flanges of both the male plug and the female plug. During this assembling process the flanges of the respective plugs are brought into flush engagement with the opposite surfaces of the panel 15 and compress the material forming said panel therebetween until the outer surface of the flange 11 on the male plug 4 is placed in aligned planar relation with respect to the outer surface of said panel 15. As the male plug 4 and the female plug 6 are brought together, outwardly extending knobs (not shown) formed on the jig or press engage and deform the flange 24 of the female plug 6 adjacent the notches 24a and protuberances 19, 2t and 231, as illustrated in FIGURE 2, at 39. This deformation of the flange 24 forms nodules on the opposite side of said flange 24. These nodules are thus pressed into the panel 15 and aid in preventing rotation of the reel supporting core, formed by the male plug 4 and the female plug 6, relative to said panel. The opening 23 formed in the end wall 22 of the female plug 6 serves as a vent allowing the escape of air which may be trapped between said plugs during assembly and equalize the pressure on each side of said wall 22.

Referring now to FIGURE 3, the reel support member is shown in the folded assembled relation with the reel '7 mounted on the supporting core. in this position the opening 3t) in the hub 29 of the reel 7 is fitted over the cylindrical wall member 18 of the female plug 5 with the protuberances 19, 2t) and 21 fitting in the grooves 31, 32 and 33. The panels 14 and of the supporting member are folded upon themselves to enclose the reel therebetween. The sleeve 34, in which the supporting unit 5 is slidably and telescopically fitted, comprises a bottom Wall 35, a pair of end walls 35, only one of which is shown in the drawings, and two opposing side panels 37 and 38. The sleeve 34 is thus formed with a rectangular open side opposite the bottom wall 35, allowing insertion of the supporting unit 5 and the reel 7 into said sleeve. When the supporting unit 5 is inserted within the sleeve 34, the wall portion 16 of said sleeve encloses the open side of said sleeve 34. The sleeve 34 may be formed of corrugated fiberboard, solid fiberboard or other material, and may be formed from a single sheet of such material which is cut, folded and glued or stapled together to form the sleeve 34 as illustrated.

While one embodiment of the invention has been shown and described, it will be appreciated that this is for the purpose of illustration and that changes and modifications can be made herein without departing from the spirit and the scope of the invention.
