bottom panel and' f ol'ded at right angles with respect to the bottom panel. End panels of double thickness are adhered to each end of the outer side and bottom panels, a top panel and inner side wall panel are integrally connected to each outer side panel. The end panels are the exact height of the outer side panels and exact Width of the bottom panel with the ends of the inner side panels abutting the inner surface of the end panels.
Backgjround of the invention This invention relates to a container having dual side walls and reinforced end panels that materially increase the stacking strength of the container. More specifically, this invention relatesto a container having dual side walls and double thickness end panels with the dual side walls being provided by folding over the extensions of the side panels and interlocking them into place in slots provided in the bottom of the container to provide an upper platform for support of upper containers stacked thereon.
In the art of shipping fruit, produce and other agricultural commodities, it is the practice to pack them in containers and ship their} to the retailers for ultimate use and sale. It is essential that the containers that are used for shipment have high stacking strength so that the containers can be stacked one on top of the other..The containers that are used for shipment of these commodities should also have strength enough to resist bulging so that regular stacks can be formed.
There have been many containers designed for use in shipping such commodities. One such design is illustrated in US. Patent No. 3,197,108, issued to Paul D. Northway. The design of this container is provided with a body portion having side walls and end walls. The end walls are reinforced with wood members laminated thereto to provide increased stacking strength in shipment. However, such a container is provided with several di'awbacks. It requires a laminating operation to adhere the wood material to the end wall panel. In the event that the end wall panel is not exactly square, the container cannot be used to stack since it would throw the entire stack out of balance. The laminating of the wood members to the end walls requires additional machinery and capital expense which is undesirable.
Summary of the invention An object of this invention is to provide a container having reinforced side and end panels that materially increase the stacking strength of the container.
Another object of this invention is to provide a container having dual spaced apart side walls and double thickness end panels which are adapted to support upper panels thereon.
Another object of this invention is to provide a container having spaced apart dual side walls and double thickness end wall panels that are provided with ease in construction and is less expensive to manufacture yet is provided with sufficient stacking strength for ultimate use as a container for shipping produce and other commodities.

' Description of the invention I 1 Referring to FIGURE 1 of the drawings, the main body blank is illustrated at 1 which includes a bottom panel 2, outer side walls 3 and 4 and inner side Walls 5 and 6. Intermediate the walls 3 and 5 is positioned a top side panel or platform 7. Also, intermediate the walls 4 and 6 is positioned a top side panel or platform 8. The ottom panel 2 is separated from the outer side wall panels 3 and 4 by score lines 9 while the outer side wall panels 3 and 4 are separated from top side panels 7 and 8 by a score line 10 with the inner side wall panels 5 and 6 separated from the top side walls 7 and 8 by score lines 11.
Glue flaps 13 are integrally connected to the bottom panel 2 and separated therefrom by score line 12. Also, glue flaps 14 are provided on the outer side walls 3 and 4 and are integrally connected thereto but separated therefrom by the score line 12.
The outer sides of the inner side wall 5 are each provided with a pair of tabs 15. Inner side walls 6 are also provided with similar tabs 16. The tabs 15 are adapted to extend into openings 17 cut into the bottom panel 2 while the tabs 16 are adapted to be extended into openings 18 cut in the bottom panel 2. Additional openings or holes 19 are formed in the bottom panel 2 as indicated at 19 to receive tabs 20 and 21 that are formed by cut lines 25 and 26 in top side panels 7 and 8. The dimensions of the inner side wall panels 5 and 6 are less than the dimensions of the outer side Wall panels 3 and 4. These dimensions are indicated at 22. The distance of the cutaway portion 22 on the panels 5 and 6 is the exact width of the end wall panel 23 as hereinafter set forth.
The end wall panel usable with the present invention is indicated in FIGURE 2 at 23 and is provided with cutout arcs 24 for ventilating purposes. The end wall panel 23 is formed the exact width of the bottom panel 2 and exact height of panels 3 and 4 and is cut from double thickness corrugated medium as indicated in FIGURE ,3.
When it is desired to assemble the container of the present invention, the container blank 1 is first bent along score lines 9 so that the outer side wall panels 3 and 4 are at right angles with respect to the bottom panel 2. The end wall panel 23 is positioned along score lines 12 and the glue flaps 13 are bent at right angles and adhered to the outer surface of the end wall panel 23. Also, the glue flaps 14 are bent at right angles with respect to the outer side wall panels 3 and 4 and adhered to the outer surface of the end wall panel 23 as indicated in FIGURE 3. The outer side walls 5 and 6 are bent along score lines 10 to form the top side panels 7 and 8 and then bent into the container along score line 11 with the extensions 15 and 16 extending into the openings 17 and 18 respectively. As is indicated in FIGURE 3, the outer edges of the inner side walls 5 and 6 abut the inner surface of the end panel 23 to provide additional rigidity in the container. With the carton in the thus assembled condition, it can be filled with agricultural commodities for shipment to the ultimate consumer. If desired, wires can be extended between the walls 3 and 5 and between walls 4 and 6 to hold all the stacks one on top of the other. When one container is stacked on top of the other, the tabs 20 and 21 extend up into the openings 19 to add additional rigidity to the stacked containers.
What is claimed is:
1. A container, comprising: a bottom panel, a pair of outer side wall panels integrally connected to the bottom panel along score lines and extending at right angles with respect to said bottom panel; a top panel integrally connected to the outer edge of each of the outer side wall panels along score lines and extending at right angles with respect thereto; inner side wall panels integrally connected to said top panels and extending at right angles thereto along score lines; end wall panels dimensioned the exact width of the bottom panel and exact height of the outer side wall panels; said end wall panels being adhered to the bottom panel and outer side wall panels by glue flaps folded along score lines; the width of the inner side wall panels being selected to abut the inner surface of the end wall panels; tabs on the lower edges of said inner side wall panels extending into openings formed in the said bottom panel; and tabs formed by cut lines through the top panels and extendable into openingsin the bottom wall panel of a container stacked thereabove.
