s Claims. (Cl.'206--60) This invention relates to a shingle package, and more particularly to the packaging of self-sealing shingles, especially asphalt strip shingles of the square-butt type that have adhesive material applied in broken or continuous lines, dots, or other figures, extending lengthwise of the-shingles. on the weather surface. The adhesive material is of suchnature and so positioned that when the shingles are applied to a roof and subjected to solar heat the butt or exposed portion of the shingles will be sealed or cemented down by the self-acting efiect of the adhesive.

Because of the adhesive material applied to the surface of the shingles, considerable difiiculty has heretofore been experienced in packing the shingles for shipment from the factory without causing them to become somewhat. deformed: while they are contained in the package, and consequently interfering with proper and effective sealing when they are applied on the roof.

The thickness of the adhesive material on the weather surface of each shingle is slight, amounting usually only to about a few thousandths of an inch. However, as in packaging a plurality of shingles are bundled in each wrapper, the cumulative effect of the thickness of the adhesive material is considerable, being enough to cause the shingles to bend out of their normally flat condition. It is common practice in the industry to pack the shingles in bundles so that a given number of bundles will contain the number of shingles required to cover a square, that is, to cover one hundred square feet of roof area.

It. is an object of'our'invention to provide a packaging fortransportation. of self-sealing shingles that will protect the contents and avoid any objectionable bending or deformation of the shingles while inthe package.

Other advantages of the invention will appear from the following description thereof, reference being had to the accompanying drawings, in which:

Fig. l is a perspective view of one form of the wrapper element of the package embodying the invention;

Fig. 2 is aperspective view of a panel or pallet for insertion in the package;

Fig. 3 is a perspective view of a modified form of the panel or pallet;

Fig. 4 is a plan view of a blank from which the wrapper element of the package may be formed, the blank in this instance having a continuous opening in the portion thereof that constitutes the bottom of the package;

Fig. 5 is a vertical view in section of the package and its contents, the latter being shown in phantom; and

Fig. 6 is a fragmentary perspective view of one form of self-sealing shingle to be bundled.

The fragmentary View of the shingle 10 illustrated in Fig. 6 is typical of one form of self-sealing shingle that is to be contained in the package. In this form, the shingle has a series of substantially rectangular forms of adhesive material 11 applied lengthwise on the upper or weather surface in a predetermined arrangement and at a prescribed distance above the inner or upper ends of the cut-outs or slots 12 that define the side edges of the so-called square-tabs" of the shingle. In this instance, the

"ice

or rear surface to prevent the shingles from sticking to-v gether when packed or stacked one upon another.

While the adhesive material is preferably in the formof separated rectangular figures, it may be applied in globules, in a continuous strip, or in other forms. In some instances the parting stripe may be eliminated and in lieu thereof the face of the adhesive may be covered with anti-stick paper or other substance that can be easily stripped or peeled olt when the shingles are to be laid or applied on a roof.

In Fig. 6, for the sake of illustration, the thickness of both the adhesive 11 and the parting stripe 13 is greatly exaggerated inrespect to that of the body of. the shingle. Usually the thickness of the adhesive is only a. few thousandths of an inch, about .020, and that of the parting stripe or material is negligible.

However, it is customary to pack the shinglesin bundles so that a specified number of bundles will contain a sufiicient quantity of shingles to cover a square of roof surface. Where the shingle bundles were packed in the conventional manner, it was found that, as the shingles are flexible, the cumulative effect of the thickness of the adhesive caused the shingles to sag and become deformed, especially if they were kept packed for any length of time before being used.

Our improved packaging supports the shingles at intervals on pallets and compensates for the increased thickopposed edges 18 of which are spaced apart. in the form of wrapper of Fig. l, the bottom has a series of alined die-cut slots or openings 19 While in the form of Fig. 5, the bottom has a single continuous opening 2%.

The package, as seen in Fig. 5, includes a plurality of pallets or panels 21 upon which stacks or catches of the shingles are supported face up. The pallets 21' are formed of fiat rectangular sheets of corrugated board or the like. which are die-cut to provide a series of slots or openings 22 or a continuous opening 23, which openings correspond substantially in position, size, and arrangement to those of the openings 19 or 20 of the wrapper and are positioned with relation to the positioning of the adhesive 11 on the face of the shingles.

Each pallet 21 not only serves to support a given number of shingles so as to prevent them from bending but also, by reason of the slots or openings therein, compensates for the increased thickness of the supported shingles resulting from the application of adhesive on' the face of the shingles.

The

openings

19, 20 and 22, 23 of the wrapper and the pallets, respectively, are preferably of such width as to accommodate the adhesive material 11 and the parting stripe 13. The spacing between the opposed edges of the flaps 17 is preferably of the same order as the width of the openings in the bottom of the wrapper and in the pallets.

In packing the shingles, the wrapper element is bent to shape and a specified number of shingles are stacked face up on the bottom Wall of the wrapper. Other shingles, usually of the same number as those supported on the bottom of the wrapper, are supported on each of the pallets that are inserted in and form a part of the complete package. The package is then bound in the usual manner with round tie-Wires or metal straps Z4.

We have found that double-faced corrugated board of the kind known in the trade as A, B, or C flute, varying in thickness from A3" to may be used satisfactorily for making the wrapper and the pallets. However, we do not limit use to these particular materials as other suitably strong and inexpensive materials may be employed.

Pallets of the form of Fig. 2 are preferred to those of the form of Fig. 3, except where the adhesive is applied as a continuous strip, because the solid uncut portions between the openings in the pallet give it additional strength, and afford additional support to the shingles stacked thereon.

In packaging self sealing square-butt shingles having an overall measurement of 12" x 36", designed to be exposed five inches to the weather, they are usually packed in bundles, each containing about twenty-seven shingles, three such bundles being suflicient to cover a square of roof area. In that case, two pallets are included in each bundle or package, as indicated in Fig. 5, and the shingles in each bundle are divided into three stacks of nine shingles each. Where shingles of different dimensions and exposures are to be packed, fewer or more shingles may be contained in each stack, and the number of pallets used in each bundle, and the number of bundles required per square, may be varied accordingly.

In storage and in shipping, a considerable number of packages of shingles are piled one upon another. Where the shingles are packed in ordinary cartons or wrappers, the weight of the pile effects a very considerable pressure on the shingles. In the case of self sealing shingles having raised adhesive areas, that pressure is concentrated largely on the high spots and tends to flatten the adhesive and/or to cause the shingles to stick together, particularly where they are subjected in storage or shipment to conditions of high heat.

The slotted wrapper and pallets of our improved package overcome these difficulties by relieving pressure on the adhesive areas (which constitute only a relatively small portion of the whole shingle area), and distributing the pressure substantially uniformly over the rest of the area.

It is to be understood that modifications in the package as herein described, and illustrated in the drawings, may be made within the scope of the invention as set forth.
