M P d Patented Feb. 19, 1935 PATENT OFFICE- CARTON George E. Whalley, Chicago, IlL, assignor to Robert Gaylord, Incorporated, St. Louis, a corporation of Missouri Mitt-5v Application November 16, 1932, Serial No. 642,830

1 Claim.

My invention relates to a carton such as that employed in the shipment of meat products. It may, however, be used in the construction of cartons or shipping cases for various other purposes.

My invention consists in interposing between inner and outer layers of the pliable material of the carton, a reinforcing member of rigid'matcrial, both for the'purpose of strengthening the carton, particularly against vertical pressur re-' sultingfrom stacking the fllledcartons, an for providing convenient means for "assembling the carton by the user.

In the accompanying. drawing, which illustrates one form of carton made in accordance with my invention, Figure 1 is a perspective view of one end of the carton, the sealing flap being in raised position; Figure 2 is an enlarged vertical section through one end of the carton; Figure 3 is a plan view of the end plate and attached reinforcing frame; and Figure 4 is a perspective view of one corner of the reinforcing frame.

The carton is made from any suitable pliable material, preferably solid fiberboard. As shown, the body of the carton is formed from a single sheet of fiberboard folded to form a bottom .1 and a pair of side panels 2. The ends of the bottom and side panels. are turned over at right angles to form end flanges 3 for securing the end plate 4 in position. Formed integral with the end plate is a sealing flap 5 adapted, when. closed, to seat against a pair of top flanges 6 formed by turning over the upper edges of the side panels. The sealing flap may extend the entire length of the carton but preferably covers onehalf, the other half being covered by a similar flap carried by the opposite end plate. In the latter case the carton is sealed by securing together the free ends of the flaps by some means, not shown, as it forms no part of the present invention.

In carrying out my invention, instead of attaching the end flanges 3 directly to the end plate 4, I interpose between said parts a reinforcing member of rigid material, preferably a frame composed of four strips 7 of wood. These strips are connected at' the cornersby lap joints, the 6 ends of the strips being provided with rabbets 8 so that the frame will present flush faces to contact withthe flanges 3 and end plate 4. While the carton may be assembled by securing the reinforcing frame to both the flanges and end plate 1 at the same time, I prefer to first attach the frame to the end plate by suitable means, such as staples 9, so that the carton may be shipped in knock-down form with these parts attached. The carton may then be assembled by attaching 15 the flanges 3 to the frame by means, suchv as staples 10, which may be driven in place by a hammer. Or, broad-headed nails or tacks may be used as the wooden frame supplies suitable holding means for such fastening devices. 20

My construction thus affords convenient means for assembly by users not provided with a sewing or stapling machine. Its principal advantage is, however, that it provides a strong light, and inexpensive reinforcement which effectively pre- 25 vents crushing'of the carton when a number of the cartons filled with meat products or other heavy contents, are piled-one upon another.

Having fully described my invention, what I claim as new'and'desire to secure by Letters Patent of the United States is: V

A carton comprising a body formed of integr side and bottom walls, said side walls being each provided with a top flange and an end flange, the bottom wall also being provided with an end flange, an integral end plateand sealing flap, the latter .being adapted to seat against the top flanges, and a reinforcing frame of rigid material positioned between the end flanges and the end plate and having its outer face secured to the former and its inner face secured to the latter.
