2 Claims.' (01. 20665) This invention relates to shipping containers for wound yarns and more particularly to containers for use in shipping a plurality of packages of wound yarn such as cones of rayon and it is an object of this invention to provide an improved container of the class described in which the cones are secured against shifting or movement under the usual handling during shipment so that the rayon yarns are not injured by chafing or harmful contacts.

In the drawings, which illustrate a preferred embodiment of this invention:

Fig. 1 is a view in vertical section through one of the units or groups in which the cones are arranged for shipment, the cones being shown partly in elevation and partly in vertical sectionj Fig. 2 is a plan view of an intermediate tray shown in Fig. 1, part of one piece of said tray being broken away; and

Fig. 3 is a view in vertical section of a plurality of the units or groups of Fig. 1 assembled in an outer casing or container.

In the shipping of cones of rayon yarns it is necessary to prevent such movement of the cones .as will cause the yarns thereon to be damaged,

by chafing or blows, against the adjacent cones or the sides of the containers and where the yarn package, such as is shown in the patent to Gibbs and Martin, No. 1;808,651, dated June 2,

1931, has been used, the yarn has been damaged because the trays have buckled and permitted the cones to be freed therefrom, particularly when the package was dropped on an end and when the box or casing has been made large enough to be used in shipping the product of the users of the yarn. Thus where the box or casing is large enough to be used in shipping woven goods, the beams being about 50 inches 40 long, the trays are not sufliciently rigid to retain the cones in position and in some instances,

the box or casing has been buckled.

In order to provide for the safe shipment of l the cones while using boxes or casings of a size suitable for the shipment of goods manufactured of the yarns, the cones of a box or casing in accordance with the invention are arranged in a plurality of groups or units, each group or unit being wrapped about with a layer of corrugated cardboard so that between thegroups or units a plurality of layers of corrugated cardboard form partitions reinforcing the box or casing. The cones of each group are divided into-layers by trays which position the cones. The trays are sufliciently rigid to retain the cones in position and reinforce the partitions formed of the wrappings about the cones as the trays are of relatively small dimensions and formed of a plurality of layers of corrugated cardboard glued together.

As shown in Fig. 1, in each group or unit into which the cones of a box or, casing are divided the cones l are arranged in four layers, of twelve cones each, the cones of the dlflerent layers being separated by trays 2 formed of two layers 01' corrugated cardboard, glued together and having their corrugations extending at right angles to each other. The lower layer 2 of the tray is provided with openings '22 which fit the conical tubes 3 of the cones but which do not permit the trays to rest on the windings of the cones. The upper layers 2 of the trays are provided with openings 2| concentric with the openings 22 which receive the lower ends of the tubes 3 so that the tubes 3 rest on the upper face of I) the lower layer 2 of the tray.. The lower ends of the tubes 3 of the bottom layer of cones are fitted into openings oi'a corrugated cardboard section 4, similar to the tray layer 2, which is glued to a wrapping strip 6 of sumcient length 86 to extend continuously about the group'or unit of cones and to provide a flap 6 which overlaps the wrapping strip for a short distance, the flap 6 being placed at the inside of the wrapping strip as shown. The corrugations of the section textend at right angles to those of the wrapping strip 6.

Between the wrapping strip 6 and the yarn on V the top layer of cones there is placed a tray 8 consisting of two layers of corrugated cardboard l8 glued together with their corrugations extending at right angles to each other and provided with openings which flt the upper ends of the tubes 3 but which do not allow the tray to engage the windings of the cones. The tray 8 is of such di- '40 mensions as to permit the flap 6 being placed inside the winding strip 6 and the winding strip 6 to form a rectangular figure engaging all of the trays 2 and the tray 8, so that the vertical side portions 6 and 6 are braced thereby. The

end of the winding strip 6 may be held in place by a gummed paper strip or other suitable means.

Thepreierred sizes 01' the boxes or cases for shipping the cones are such that two or three such groups or'units as is shown in .Fig. 1 may be shipped in a single box or case, three such groups or units being shown in the box I! of.

Fig. 3 which is formed of the ply-wood or veneer sections l2, reinforced at their edges by wood 1 frames it which serve to secure the sections together so as to form a complete box or case.

Positioned in the box or container the plurality of groups or units tightly fill the same and the vertical portions of the wrapping strips 6 serve as reinforcing members or partitions, particularly where the vertical portions 6 and 6 of adjacent wrapping strips are in contact throughout between the units or groups owing to the flaps 6 being placed inside. The vertical portions of the strips 6 are braced at spaced points 'by the trays 2 and 8 and by the corrugated board sections 4 and the top and bottom portions of the winding strips. As thus assembled the container is reinforced and the trays are sufliciently rigid to prevent buckling so that the cones are retained in position and the windings are not damaged.

While reference has been made to cones it is to be understood the invention is equally applicable where the yarn is wound in packages of other form as cops, spindles, bobbins, etc.

What is claimed is:

1. A yarn package comprising a container, superposed rows of yarn cones therein, tray members having cone positioning means for spacing the cones and forming re-enforcing partitions in the package, a cardboard wrapping strip surrounding the cones and contacting and being braced by the ends of the tray members, the uppermost tray member being shorter than the other tray members which are of uniform length by an amount substantially equal to the thickness of the wrapping strip, the wrapping strip having a fiap portion at one end extending be-' tween and braced on one side by the end of the upper tray member and on the other side by the adjacent portion of the wrapping strip, the sides of the container engaging the wrapping strip throughout.

2. A yarn package comprising a container, units of superposed rows of yarn cones therein, tray members having cone positioning means for spacing the cones and forming re-enforclng partitions in the units, cardboard wrapping strips surrounding the cones and contacting and being braced by the ends of the tray members in the units, the uppermost tray members being shorter than the other tray members which are of uniform length by an amount substantially equal to the thickness of the wrapping strip, each wrapping strip having a flap portion at one and extending between and braced on one side by the end of the uppermost tray member of the unit and on the other side by the adjacent portion of the wrapping strip, the wrapping strips on adjacent sides of the units being in engagement throughout and the sides of the container engaging the wrapping strip throughout.
