GEORGE F. MART N BY 'A;%JV EY United States Patent 3,172,534 CONTAINER FOR PACKAGING YARN ON SPOOLS OR BOBBINS George F. Martin, Cincinnati, Ohio, assignor to The Mead Corporation, Dayton, Ohio, a corporation of Ohio Filed Oct. 27, 1961, Ser. No. 148,181 1 Claim. (Cl. 20665) This invention relates to a method and container for packaging yarn on spools or bobbins.

Generally, there is provided a carton formed from a single rectangular blank of corrugated cardboard or the like and having a row of panels foldable about vertical scored fold lines to define the side and end panels of the carton. The top and bottom edges of the side and end panels have overlapping closure flaps integrally connected thereto along scored hinge fold lines. The top and bottom closure flaps have evenly spaced aligned apertures therein which protectively and accurately position spools or bobbins of yarn. The upper bare ends of the spools project upwardly through the apertures in the upper carton closure and axially into the hollow bases of spools or bobbins in a like carton stacked thereon in a shipping container holding a plurality of tiered cartons arranged in one or more rows.

It is an object of the present invention to provide a simple, efiicient and economical method and means for packaging yarn wound on conical hollow spools in which a plurality of rows of the wound spools are packaged in cartons having aligned apertures in top and bottom closure flaps for protective positioning of the spools thereby and by a telescopic interengagement produced by the necks of the spools in one carton projecting through aligned carton apertures into the hollow bases of spools in a superimposed like carton.

It is another object of the invention to provide a carton of the type disclosed formed economically from a single rectangular foldable blank.

It is a further object of the invention to provide a carton of the character described having overlapping top and bottom flaps held in alignment by, and holding properly spaced and in alignment, rows of conical bobbins having bare necks extending upwardly through the apertures in the top closure flaps and through the bottom apertures of a superimposed like carton.

It is still another object of the invention to provide a plural carton package in which the cartons of the bottom layer are provided, if desired, with spacers to prevent relative spool movement.

Other and further objects of the invention will become apparent from a reading of the following specification, taken in conjunction with the drawings, in which:

FIGURE 1 is a plan view of a die cut and scored blank for one of the cartons;

FIGURE 2 is a perspective view of one of the cartons ready for filling with spools of yarn;

FIGURE 3 is a perspective view of a closed but empty carton;

FIGURE 4 is a perspective view illustrating the packing of rows and tiers of the cartons in a shipping container;

FIGURE 5 is an elevational view, in section, taken on line 55 of FIGURE 4;

FIGURE 6 is an enlarged fragmentary elevational view showing the telescopic nesting interengagement between the spools of stacked cartons;

FIGURE 7 is a perspective view of the closed package of FIGURE 4; and,

FIGURE 8 is a perspective view showing eight containers mounted on a shipping pallet.

With reference to FIGURES 1, 2 and 3 of the draw- 3,172,534 Patented Mar. 9, 1965 ice ings, numeral 10 generally designates a rectangular die cut and scored rectangular blank of corrugated cardboard or equivalent material. Three vertical parallel scored

fold lines

11, 12 and 13 divide the blank 10 into a horizontally extending row of edge-joined panels 14 through 17. Panels 14 through 17 are foldable, as best seen in FIGURE 2, to define the circumferentially continuous side and end walls of a carton, generally designated 18, when the

free ends

19 and 20 of the

extreme panels

14 and 17, respectively, are abutted at the corner 21 of carton 18. The joint at 21 may be maintained closed solely by the effect of the overlapping closure panels hereinafter described, or optionally by a strip of adhesive tape (not shown) extending along and bridging the joint 21.

Scored

hinge fold lines

22 and 23 and die cut slits 24 define top closure flaps 25 through 28 and bottom closure flaps 29 through 32.

In the disclosure of FIGURE 2, bottom closure flaps 29 through 32 have already been folded to produce the bottom of the carton in a manner substantially identical to the folding of top closure flaps 25 through 28, as illustrated by FIGURES 2 and 3. The

end closure flaps

26 and 28 are first bent horizontally toward each other, after which the longer closure flaps 25 and 27 attached to

side panels

14 and 16, respectively, are folded down over

flaps

26 and 28.

The

longer closure flaps

25, 27, 29 and 31 are provided with rows of equally spaced apertures 33 positioned for vertical alignment of the apertures in the upper closure flaps with those in the lower closure flaps. The

shorter closure flaps

26, 28, and 32 are also provided with apertures 34 of the same size and spacing and positioned so as to align the upper and lower apertures 34 both with each other and also the end apertures 33 of the overlapping

longer flaps

25, 27, 29 and 31, as shown best in FIGURES 3 and 6.

FIGURES 4, 5 and 6 show how rows of spools or bobbins having yarn wound thereon are packaged in cartons 18 and how a plurality of said cartons (nine in the illustrative example of FIGURES 4 and 5) can be packaged in rows and tiers in a master container or carton of conventional construction, generally designated 35. Spools or bobbins, generally designated 36, each comprise a conically tapered tubular spindle 37 formed of laminated paper or other suitable material. Yarn 38 is wound on each spindle 37 in a predetermined amount and to a predetermined diameter and also so as to leave free of yarn a considerable portion of the upper smaller end of each spindle 37 to constitute a bare neck portion 39 of a length sufiicient to extend upwardly through the aligned

apertures

33 and 34 of top closure flaps of carton 18 in which spools 36 are packaged and also upwardly through the aligned

apertures

33 and 34 of a similar superimposed carton 18. A neck portion 39 telescopically enters a hollow base 40 of a spool spindle 37 in said superimposed carton (FIGURES 5 and 6).

Since the cartons in the bottom row, or in other words the bottom carton of each tier, do not have neck portions 39 projecting upwardly into the bases 40 of spindles 37 contained therein, it is desirable to employ spacing means, such as strips 40' of corrugated cardboard positioned vertically between adjacent spools 36 so as to prevent movement of their lower ends during handling or shipping of the packaged spools.

To facilitate packaging of cartons 18 in the master container 35,

end panels

15 and 17 of each carton 18 may be provided with die cut hand openings 41 which form handles.

FIGURE 7 shows how the master container 35, having packed therein nine of the cartons 18, is closed and sealed by the use of strips 41 of adhesive tape. In FIGURE 8, four master cartons are shown mounted upon a pallet, generally designated 42, fastened thereto by metallic straps 43 for convenient handling and shipping,

While but one form of the invention has been shown and described herein, it will be readily apparent to those skilled in the art that many minor modifications may be made without departing from the spirit of the invention or the scope of the appended claim.

What is claimed is:

A package comprising a master container, a plurality of horizontally arranged rows of cartons, each of said rows being in vertically stacked relation, a plurality of bobbins of yarn or the like therein wound on spool spindles in each carton, said spindles being upwardly tapered tubes the lower ends of which extend somewhat below the lower surfaces of said bobbins and the upper ends of which extend upwardly for a considerable distance above the upper surfaces of said bobbins and which are of a diameter snugly telescoping into the bases of like spindles axially disposed in cartons thereabove, said cartons each comprising a blank of relatively still sheet material die cut and scored to define a row of edge-joined panels foldable to form the side and end walls of said carton and a plurality of top and bottom closure flaps hingedly joined along scored fold lines to said side and end wall panels, said closure flaps having rows of substantially equally spaced vertically aligned apertures therein of a size snugly receiving the upper exposed ends of said spindles therethrough to protectively and accurately space said bobbins in said carton, said apertures being of diameters somewhat smaller than the outside diameters of the base ends of said spindles, whereby said bobbins are held protectively spaced from the bottom of said carton, and means for spacing and holding against relative movement the lower ends of said bobbinsrin the lowermost carton of each row of cartons, said means comprising strips of sheet material extending vertically between and in abutting relation to the lower portions of adjacent bobbins and rows thereof in said lowermost cartons.
