This invention relates to cartons, and relates more particularly to cartons for storing and shipping packages of yarn.

A considerable amount of yarn produced in the textile industry -is wound on suitable supports with the windings so positioned thereon that the ends of the support extend beyond the yarn windings. During the storing and shipping of these packages of yarn, they are rigidly supported to prevent them from rubbin against each other or against the Walls of the carton in which they are enclosed, since such rubbing would mar at least the outer layers of yarn on said packages. Heretofore, it has been the practice to provide such rigid support by engaging the free ends of the yarn package supports with an insert which is positioned in the carton in which the packages of yarn are stored and shipped. While such inserts will furnish adequate support for the packages of yarn if properly designed, their use involves an additional expense and additional labor is required for their assembly.

It is an important object of this invention to provide a carton for storing andshipping packages of yarn which will be free from the foregoing and other disadvantages of the prior cartons.

A further object of this invention is the provi sion of a carton for storing and shipping packages of yarn, which carton will rigidly support the packages of yarn without the use of inserts or other supporting means separate from the carton.

Other objects of this invention, together with certain details of construction, will be apparent from the following detailed description and claim.

My invention comprises a yarn package storing and shipping carton having the inner surfaces of its top and bottom walls spaced apart a distance equal to or slightly larger than the height of the yarn windings on said packages, and having vertically aligned apertures in its top and bottom walls engaging the free ends of the yarn package supports. Any desired number or packages of yarn having any shape and dimensions may be packed in a single carton by varying the physical dimensions of the carton, and the size, spacing and number of apertures in the top and bottom walls thereof. For shipping, a number of cartons may be stacked, covers fitted over the top and bottom of the stack to close the apertures therein, and the completed stack bound with steel straps or the like, forming a strong and inexpensive shipping package, which will rigidly support the packages of yarn against rubbing and damage.

The carton of this invention is particularly adapted for storing and shipping yarn packages in which the yarn is wound into the form of a '1 Claim. (01. 229-40) cone on a support which comprises a hollow men ber of generally tapered shape whose top or narrower end extends from the yarn windings a greater distance than does its base or broader end. With said cones of yarn, the thickness of the bottom wall of the carton should be at least equal to the distance the base of the yarn package support extends from the yarn winding so that the base of the yarn package supports will not protrude from the carton when the cones are placed therein. On the other hand, the thickness .of the top wall of the carton, which may be equal to that of the bottom wall, should be less than the distance the top of the yarn package'supports extend from the yarn winding so that the top of the yarn package supports will. protrude from the carton when the cones are placed therein. Then, when the cartons are stacked, the tops of the yarn package supports in one carton will nest in the bases of the yarn package supports in the carton above, thus aligning the cartons and maintaining their alignment.

A preferred embodiment of this invention of a carton for storing and shippin cones of yarn is illustrated in the accompanying drawings in which Fig. 1 is a plan view of a blank from which the cartonis produced,

Figs. 2, 3, 4 and 5 are perspective views showing the successive steps in setting up the carton,

Fig. 6 is a perspective view of a stack of cartons ready for shipment, and

Fig. 7 is a detail view, on an enlarged scale. showing the nesting of the cones of yarn to align the cartons.

Referring now to the drawings, the reference numeral II designates a blank, which may be cut from corrugated board, cardboard, or any other suitable material by means of a die of the desired configuration. The cutting die may also impress fold lines into the blank or these lines may be impressed in a subsequent operation, as is well known in the art. The blank I I comprises 9. rectangular portion, indicated enerally by reference numeral I2, which, when bent along fold lines I3,- I4 and I5, forms the side-walls I6, II, I8 and I! of the carton. integrally connected to the side walls I6, I'i, I8 and I9 along fold lines 2|, 22, 23 and 24 are

rectangular flaps

25, 26, 21 and 28, which form the bottom of the carton. Similarly,

rectangular flaps

29, 3|, 32 and 33 integrally connected to the side walls I6, I'I, I8 and I9 along

fold lines

34, 35, 36 and 31 form the top of the carton. Each of the

rectangular flaps

25, 26, 21, 28, 29 and 32 is provided with a plurality of regularly disposed apertures 38 of a diameter slightly larger than the diameter of the base of the suphave a diameter equal to the diameter of the apertures 39 rather than the apertures 38. The

apertures

38 and 39 are positioned so as to be in vertical alignment when the carton is set up to support the cones of yarn properly.

To set up the carton of this invention, which is indicated generally by reference numeral 4|, the blank H is bent into a rectangle along the fold lines l3, l4 and I5 and the abutting edges of the side walls It and 19 are fastened together with a strip 42 of gummed paper or tape as shown in Fig. 2. Thereafter, the

rectangular flaps

26 and 28 are bent inwardly along the

fold lines

22 and 24, and the

rectangular flaps

25 and 21 are bent inwardly along the fold lines 2! and 23 to form the bottom wall of the carton as shown in Fig. 3. If desired, the bottom wall of the carton may then be reinforced and sealed by means of strips of gummed paper or tape, staples, or the like. After the bottom wall of the carton has been formed, the cones of yarn, indicated generally by reference numeral 43, (Fig. 7) are packed therein. The cones 43 each comprises a tapered, hollow yarn package support 44 having a base 45 of somewhat smaller diameter than its top 46, and having a yarn winding 41 so positioned thereon that the top 4'3 of said yarn package support extends from said yarn winding a greater distance than does its base 45. The cones 43 are set into the carton with the base 45 engaging the apertures 33 and, since the thickness of the bottom wall of the carton is at least equal to the distance the base 45 extends from theyam winding 41, said base will not protrude from the carton. When the carton is fully packed, the rectangular flaps 3i and 33 are bent inwardly along the

fold lines

35 and 31 as shown in Fig. 4, and the

rectangular flaps

29 and 32 are bent inwardly along the fold lines 34 and 36 as shown in Fig. 5. The apertures 39 in the rectangular flaps 3i and 33 will engage the tops 46 of the yarn package supports 44 snugly, to support the cones of yarn rigidly. Since the thickness of the top wall of the carton is less than the distance the top 46 of the yarn package support 44 extends from the yarn winding 41, the top 46 will protrude from the carton and, when the cartons are stacked, the top 46 will nest into the base 45 of the yarn package support 44 in the carton above aligning. the cartons as shown in Fig. '7. If desired, the top wall of the carton may then be reinforced and sealed by means of strips of gunimed paper or tape, staples, or the like.

For shipping, a plurality of the cartons 4| are stacked with the tops 46 of the yarn package supports 44 in one carton nesting into the bases 45 of the yarn package supports 44 in the carton above, and the stack sealed at its base with a cover 43 of corrugated board or the like and at its top with a cover 49 of similar material. The completed stack is then bound with a steel strap 5|, whose ends are fastened together with a seal 52 to form a strong and inexpensive shipping package.

As shown in'the drawings, the rectangular flaps 28 and 23, which have a combined width approximately equal to the length of the side wall l8 of the carton, are not of equal width, the flap 26 being narrower than the flap 23. The use of flaps of unequal width is preferable whenever an odd number of rows of cones, or other packages of yarn, are to be packed in a single carton, since it permits each of the apertures 39 that engage the central row of cones to be formed entirely from one or the other of said flaps, with one flap having an even number and the other flap an odd number of rows of apertures therein. On the other hand, if the flaps were of equal width, the apertures that engage the central row of cones would lie on the meeting line of the flaps and would have to be formed from both flaps, producing a less rigid support for the cones. The flaps 3| and 33, which also have'a combined width approximately equal to the length of the side wall I6 of the carton, are similarly of unequal width to permit each of the apertures 39 extending therethrough to be formed entirely from one or the other of said flaps.

It is to be understood that the foregoing detailed description is given merely by way of illustration and that many variations may be made therein without departing from the spirit of my invention.

Having. described my invention, what I desire to secure by Letters Patent is:

A carton comprising side walls, a pair of flaps of unequal width extending from the lower edge of two opposite side walls and forming a bottom cover for said carton, said flaps lying in a common plane with their opposed free edges in substantially abutting relation, a" pair of flaps of equal width extending from the lower edge of the other two opposite side walls and overlying said bottom cover, said flaps lying in a common plane with their. opposed free edges in substantially abutting relation, a pair of flaps of unequal width extending from the upper edge of the two opposite side walls and forming a. top cover for said carton, said flaps lying in a common plane with their opposed free edges in substantially abutting relation, 2. pair of flaps of equal width extending from the upper edge of the other two opposite side walls and overlying said top cover, said flaps lying in a common plane with their opposed free edges in substantially abutting relation, the narrower of each of said pairs of bottom and top cover flaps having a single row of apertures therein and the wider of each of said REFERENCES CITED The following references are of record in the file of this patent:
