STACKING BOX OR TRAY Filed Oct. 4. 1946 INVENTOR.

mlhn "M 6 7/ MN I Patented Sept. 25, 1951 UNITE sTA Es PATENT OFFICE 2,569,205 STACKING BOX OR TRAY Fred J Ullrich, Kalamazoo, Mich, assignor to Lee A. Fordon, Detroit, Mich.

Application October 4, 1946, Serial No. 701,286

stock and at the same time one which is strong and rigid.

Second, to provide a stacking box or tray which is well adapted for use in storage or shipment of small articles or articles which require shallow trays or boxes to avoid the load which would result from piled up or superimposed articles.

Further objects relating to details and economies of the invention will appear from the description to follow. The inventionis defined and pointed out in the claims.

A structure embodying the features of the invention is illustrated in the accompanying drawing in which:

Fig. 1 is a top perspective view of a stacking box or tray embodying my invention with the stacking bails or irons in erected position.

Fig. 2 is an enlarged fragmentary view Lof a corner of the structure shown in Fig. 1 with parts broken away and in section to illustratestructural details.

Fig. 3 is a fragmentary view of a plurality of the stacking boxes or trays in stacked position within a shipping box or container.

Fig. 4 is an enlarged fragmentary side elevation with the stacking bail in collapsed position at the end of the tray.

Fig. 5 is a fragmentaryperspective view of a modified form or embodiment of my invention. In the embodiment shown in Figs. 1 to 4 inclusive, the box or tray comprises a bottom I and

side walls

2, 2 and

end walls

3, 3 formed of a single blank or sheet of bendable material such as metal or fibre, the structure illustrated being formed of metal. ner flaps 4 lapped upon and secured to the inner sides of the side walls by rivets 5. The upper edges of the side walls are rolled outwardly to provide bead-like rim portions 5 which embrace the reinforcing rods 1 formed of wire. These reinforcing rods project at the ends of the rim rolls 6 and are coiled to provide eyes ll.

The end walls 3 have outwardly rolled upper edges providing bead-like rims 8 which are adapted to serve as sockets or bearings for the pintles 9, extending inwardly from the arms I!) of the stacking bails or irons II. The eyes H of the reinforcing rods 1 sustain the major part of the stress on the stacking bails when they are used for handles as is common practice, while the The end walls are provided with cor- 7 Claims. (01. 220-97) pintles serve as reinforcing members for the end walls. It'will be noted that they extend to approximately abutting relation as shown in Fig. 1.

The load of superimposed boxes or trays is sustained by the reinforced side walls so that the walls of the box or tray may be formed of comparatively light material and at the same time carry heavy loads.

In Fig. 3 I illustrate three of the trays or boxes in stacked relation Within a shipping container l2.

."The longitudinal ribs [3 of the stacking irons or bails are downwardly offset so that the bottom of one box or tray is supported within the upper end of the lower box or tray and lateral shifting movement prevented.

In the modification shown in Fig. 5 the side and end walls [4 and I5 are offset outwardly at 16, the outwardly offset portions ll thereof receiving the downwardly facing channel-shaped rim portions l8. These rim portions have their ebs l9 conformed to receive the pintles and I reinforcing rods 2|.

. The rim members are secured by means of rivets 22. it is desired to provide a still stronger or more, rigid structure or where the wall stock is such that it does not permit effective rolling to form the bead-like rim portions, for example when formed of fibre. Metal rim members l8 are then employed.

I have illustrated and described my invention in highly practical embodiments thereof. I have not attempted to illustrate or describe other embodiments or adaptations which I contemplate, as it is believed that this disclosure will enable those skilled in the art to embody or adapt my invention as may be desired.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

1. A stacking box or tray comprising, a bottom and side and end walls formed integrally of bendable sheet stock, the end walls having corner flaps disposed upon and secured to the inner sides of the side walls, the upper edges of the walls being rolled outwardly to provide bead-like rim portions, reinforcing rods arranged in the rim portions of the side walls to project therefrom and terminating at each end in eyes, the beadlike rims of the end walls constituting pintle bearings aligned with the openingsof said eyes, stacking bails provided with arms at their ends terminating in inturned pintles disposed through said eyes and extending into bearings, said pintles These rim members are used Where.

coacting to provide reinforcing members for the rim of the end walls and extending substantially the full length thereof.

2. A stacking box or tray comprising, a bottom and side and end walls formed integrally of bendable sheet stock, the end walls having corner flaps disposed upon and secured to the inner sides of the side Walls, the upper edges of the Walls being rolled outwardly to provide bead-like rim portions, reinforcing rods arranged in the rim portions of the side walls to project therefrom and terminating at each end in eyes, the headlike rims of the end walls constituting pintle bearings aligned with the openings of said eyes, stacking bails provided with arms at their ends terminating in inturned pintles disposed through said eyes and extending into bearings.

3. A stacking box or tray comprising, side and end walls formed of bendable sheet stock, the upper edges of the walls being rolled to provide bead-like rim members, reinforcing rods arranged in the rims of the side walls to project therefrom and terminating at each end in eyes, the rims of the end walls constituting pintle bearings aligned with the said eyes, stacking bails provided with arms at their ends terminating in inturned pintles disposed through said eyes and extending into bearings, said pintles coacting to provide reinforcing members for the rim of the end walls and extending substantially the full length thereof.

4. A stacking box or tray comprising, side and end walls formed of bendable sheet stock, the upper edges of the walls being rolled to provide bead-like rim members, reinforcing rods arranged in the rims of the side walls to project therefrom and terminating at each end in eyes, the rims of the end walls constituting pintle bearings aligned with the said eyes, stacking bails provided with arms at their ends terminating in inturned pintles disposed through said eyes and extending into bearings.

5. A stacking box or tray comprising, side and end walls formed of sheet stock and having outwardly offset upper edges, reinforcing rim members of channel section embracing the outwardly ofiset portions of said walls, and having their web portions conformed to provide bead-like rims, reinforcing rods arranged in the beads of the side walls to project therefrom and terminating at their ends in eyes, the beads of the end walls constituting pintle bearings aligned with said eyes, and stacking bails provided with pintles disposed through said eyes and extending into said bearings.

6. A stacking box or tray comprising, side and end walls formed of sheet stock, reinforcing rim members of channel section embracing the upper edges of said walls, reinforcing rods arranged in the rim members of the side walls to project therefrom and terminating at their ends in eyes, the beads of the end walls constituting pintle bearings aligned with said eyes, and stacking bails provided with pintles disposed through said eyes and extending into said bearings.

7. A stacking box or tray comprising, side and end walls formed of sheet stock and having tubular reinforcing rims, reinforcing rods arranged in the rims of the side walls to project therefrom and having eyes at their ends, the rims of the end walls constituting pintle bearings aligned with said eyes, and stacking bails provided with pintles disposed through said eyes and extending into said bearings.
