SHIPEING CASE.

Application filed December 15, 1922. Serial No. 607,023.

. To all whom it may concern: Be it known that I, HERBERT R. Buss, a citizen of the United States, residing at Niagara Falls, in the county of Niagara and State of New York, have invented certainnew and useful Improvements in Shipping Cases, of which the following is a specification.

This invention relates to shipping cases and has for its object a composite shipping case constructed of a fiber board and corrugated board. The corrugated board is desirable for several reasons, one of them is that it is lighter than fiber board and an other is that it is cheaper. However, heretofore it has never been possible to successfully wire stitch corrugated board for the reason that the stitches tear out. For this reason the railroads at present require cloth taping 2 of the jointure or manufacturers seam on the slotted corrugated container. 1 have found, however, that by combining fiber board and corrugated board that the wire stitches will hold successfully when clenched in solid fiber or tough board. It is therefore, possible to build a composite fiber board and corrugated boardbox which is wire stitched and thereby have the advantages of corrugated board for the major portion thereof, to wit: lightness, cheapness and yieldability. v

l have found that by utilizing a box made from three separate blanks, that two of these blanks can be made of one material and another blank be made of the other material. With blanks formed as I show here, and hereinafter described, it is possible to get joints at all corners of the body which are to be stitched, of which one member at the seam is corrugated board and the other member at the corner is solid fiber board. Also when the box is sealed one member along the sealing seems is solid fiber board and the other corrugated board.

In the drawings: Fig. l is a perspective of my composite shipping case sealed.

Fig. 2 is a perspective of the same before it is sealed.

Fig. 3 is a section on the line 3-3 of F1%..1. 1g. 4 1s a section on the line H of Fig 1,

ig. 5 is an enlarged section showing one of the corners.

Fig. 6 is a plan view of the body blank.

Figs. 7 and 8 are views of the two end blanks.

Referring to Fig. 6 it will be seen that the main or body blank is made up of a single strip of material scored to form the side walls a, and b the bottom wall 0 and the cover wings d and 6. At the sides of the bottom and side walls are corner flaps f. Now referring to Fig. 2 and Fig. 4 it will be seen by the cross section that this blank is made of corrugated board, or a tender board having two linerswith a corrugated filler. This filler has a very low test in comparison to the filler on solid fiber board and when the corrugation is crushed fiat by a wire staple, it has not sufiicient thickness or strength to give body to the sheet of which it is a part, for the purpose of holding the legs of a wire stitch.

Referrin to Figs. 7 and 8, it will be seen that the end walls 9 and h are scored at their tops to form cover wings g and h. Referring to Fig. 4 and Fig. 5, it will be seen that these end blanks are made of solid board such as fiber board, or tough board.

Now fiber board has long been sucessfully wirestitched, but so far as I am aware, corrugated board has never been successfully wire-stitched, for the reasons above stated and that the ends of the staple easily tear out of the weak corrugated board; the result has been that the railroads of the country will not permit wire stitching of the manufacturers seam on the regular slotted corrugated container so widely used for transportation of goods and discourage such stitching in the sealing of the flaps of such containers. However, I have found that by employing solid or strong fiber board for the base of the stitch to anchor the free ends k of the wire stitch as shown in Fig. 5, that a box of this kind is substantially as strong as one constructed entirel of fiber board. It makes the box lighter, it is cheaper, and for some kinds of goods, such as fragile goods, it makes an ideal shipping case. It wholly eliminates the necessity of gluing, taping or silicating joints both in the building of the body of the case and in sealing the case.

To get joints both in the body of the case and in the sealing of the case which present one portion of corru ated board and one portlon of fiber board, I em 10 the blanks such as shown and describe It will be seen that either the end or side walls of the case, which are preferably of fiber, are stitched to the main body blank by folding the corner flaps over the end walls and driving in wire stitches from the outside, which will thereby anchor on the free ends of the stitches in solid fiber.

When the sealin is done, the cover wings g" and h of fiber oard are folded. in while the cover win s d and e of corrugated board are fol ed and lapped over cover wings g and h. By inserting a blade anvil in the slot j, between the cover wings g and h, the stltches may be takenin the order enumerated. Inasmuch as this method of stitching the top is no part of the present invention and is explained in my co-pending application No. 605,303 it is unnecessary here to describe it in detail.

It will be apparent that the invention here described has a broader aspect than. simply corrugated board and fiber board. The essence of the invention resides in the combining of a tough solid board with a lighter tender board, and arranging them so thatthe Wire stitches or metal farteners may be anchored in the tough board so as not to tear out.

What I claim is:

1. In a shipping) case, the combination of a plurality of lanks for the exterior walls of the case, some constructed of fibre board and others of corrugated board, said blanks being matched together in the completed case to provide one or more seams in which one member of the seam is fibre board and the other member, corrugated board, and wire stitches driven mites? their free ends anc ored in the fibre board.

.2. In a shipping case, the combination of a plurality of blanks for the exterior walls of the case, some of which are constructed of fibre material and the other of corrugated board, the said blanks being arranged to match together to provide all the seams of the body of the case, with one member of fibre material and one member of corrugated material, and wire stitches driven through the corrugated material and clenched on the back of the fibre material.

3. In a shipping case, the combination of a plurality of blanks some of which are constructed of fibre material and the other of corrugated board, said blanks being arranged to match together to provide all the seams the same in the body and in sealing so that one member in each seam is of fibre material and one member of corrugated board, and wire stitches driven through the corrugated material and clenched on the back of the fibre board.

4:. In a shipping case, the combination of two end blanks each having integral cover wings and constructed of tough material, a single body blank forming cover wings, side walls and bottom wall and constructed of tender and easily torn material and having at its sides corner flaps adapted to be tolded over the end blanks and Wire stitches driven through the corner flaps and clenched on the underside of the end blanks so constructed of toughmaterial.

In testimony whereof I afiix my signature.

HERBERT R. BLISS.
