JAME Rb g MIL/YE BE T E. JOHNSTON W c. MILL A TTORNEYS United States Patent US. Cl. 229-27 2 Claims ABSTRACT OF THE DISCLOSURE A container having a partition longitudinally positioried therein for receiving poultry or meat on each side of said partition with substantially open end closure flaps with reinforcing panels extending along the partition to materially increase the stacking strength.

RELATED CASES This is a continuation of application Ser. No. 628,399 filed Apr. 4, 1967, now abandoned.

BACKGROUND OF THE INVENTION In the manufacture of containers for shipping or storing meats or the like it is the practice to place the commodities within a regular slotted container and seal the same. It is desirable to provide ventilation openings in the container when the meat is to be subsequently frozen to allow the cooling medium to properly circulate within the container. Thus, circulation openings are provided through the walls of the container in the form of small circular holes in the predetermined pattern or in a random manner. These openings, however, must not weaken the stacking strength of the container. Accordingly, the number of openings are limited which results in poor circulation within the container. Examples of such structure are illustrated in US. Patents Nos. 2,894,672 and 2,005,597.

BRIEF DESCRIPTION OF THE PRESENT INVENTION The present invention provides a container having a body shell which is rectangular and which is provided with a partition intermediate two of the walls. The end closure flaps of the container are provided with openings substantially the entire cross-section of the container so as to allow the cooling medium to readily circulate within the container to freeze or cool poultry or the like packed within the container. However, notwithstanding the substantially large openings at the end panels, a reinforcing panel is provided along the partition member which substantially increases the stacking strength of the container so that the same may be stacked one upon the other without detrimental effects to the container.

FIGURE 7 is a perspective view of a stack of conice tainers with one of the end closure flaps folded underneath the container and the end open so as to receive cooling medium.

FIGURE 8 is a view similar to FIGURE 7 but with the end openings closed.

DETAILED DESCRIPTION OF THE INVENTION Referring to FIGURE 1, the container blank 1 is provided with upper and lower horizontal score lines 2 with a plurality of vertical score lines 3 which divide the blank into a first side panel 4,

end panels

5 and 6, second and

third side panels

7 and 8, partition panel 9, and glue flap 10. A glue line 11 is provided on side panel 8 for a purpose to be hereinafter set forth.

Above and below horizontal score line 2 each of the

aforementioned panels

4, 5, 6, 7, and 8 are provided with end closure flaps. Panel 4 is provided with a solid end closure flap 12, with

panels

7 and 8 being provided with

closure flaps

13 and 14.

Panels

5 and 6 are also provided with

end closure flaps

16 and 17 with a reinforcing flap 18 being hingedly connected to the partition member 9. Each of the end closure flaps are separated from each other by slots '19 as is conventional in the art.

Each of the

end closure flaps

16 and 17 are provided with substantially rectangular cut-out portions 23 and 2-6. The cut-out portion 23 forms

legs

24 and 25 on the end closure flap 16 that are perpendicular to each other, while the cut-out portion 26 provides legs 27 and 28 on the end closure flap 17 that are also perpendicular to each other. The

legs

24 and 27 are adapted to come together at the center of the container when it is erected and filled to distribute weight above the carton more uniformly over the entire surface area. The legs 25 and 28, however, when folded into a closed position, as indicated in FIGURE 6, provide additional stacking weight since they are vertical. With the

legs

24 and 27 folded into the closed position the end result is a substantially rectangular opening 33 within the end of the carton; see FIGURE 6. The

end closure flaps

13 and 14 are also provided with cut-out

portions

20 and 29 which are rectangular in configuration. The cut-out portion 20 forms

legs

21 and 22 perpendicular to each other, while the cutout portion 29 forms

legs

30 and 31 that are perpendicular to each other. As is illustrated in FIGURE 2, the

legs

22 and 31 overlap each other to form an end closure flap indicated at 15 and form a substantially rectangular opening 32 Within the end closure flap 15. The opening 32 is adjacent to and is coaxial with the opening 33 formed by the

closure flaps

16 and 17 as indicated in FIGURE 6.

When it is desired to assemble the container the blank 1 is folded along score line 3 that separates

panels

5 and 7, and the glue flap 10 is adhered substantially at the center of the panel 4. Next, the blank is folded along score line 3 separating panels 4 and 6, and the glue line 11 is adhered to the opposite surface as indicated in FIGURE 2. In this position the

panels

13 and 14 form the end closure panel 15 while the

panels

7 and 8 together form a side panel of the container the same size as panel 4.

When it is desired to fill the container of the present invention with poultry or the like, it is erected to a rectangular configuration as illustrated in FIGURE 3. This may be brought about either manually or by machine. Thereafter the partition -flap 18 is folded adjacent to the partition member 9 as indicated in FIGURE 4. With the partition flap 18 in this position the stacking strength of the end of the container is materially increased because of the double thickness. Next, poultry 34 or the like is loaded into the two compartments so formed, as indicated in FIGURE 5.

The container that has been so filled is then moved to an end flap closing machine 35 and moved therealong by a conveyor belt 3 6. As the filled container moves toward the machine 35 the end closure flaps 17 engage a leading plow member 37 having out-turned end 38 which folds the flap -17 to adjacent the end of the box. Thereafter end flaps 16 are folded inwardly toward the box by a curved radial plow member 39 which is affixed to a rotatable shaft 40 mounted in a bearing 41 in the support strap 42. The arm .39 is rotated by the shaft 40 which is connected to a power source (not shown). As the filled container moves past the

plows

37 and 39, an upper plow 43 having an up-turned end 44 engages the end closure flap 15 which folds the same downwardly to substantially close off the end of the container with openings 33 and 32 as indicated in FIGURE 6. Simultaneously with folding the flap 15 downwardly the flap 12 engages a lower plow 45 having an up-turned end 46 which folds the flap 12 downwardly so that it can subsequently be moved to underneath the box, as illustrated in FIG- URE 7.

The container so filled may be stacked and then conveyed to a freezing compartment where the poultry or the like within the container is frozen. The flap 12 may be adhered or otherwise affixed to the bottom of the container, while the

flaps

15, 16, and -17 are either stapled or adhered to each other in a conventional manner. When the poultry has been frozen the flap 12 is folded back around to close the opening at the end of the box, as illustrated in FIGURE 8.

While specific details of the preferred embodiment have been set forth above, it will be apparent that many changes and modifications may be made therein without departing from the spirit of the invention. It will therefore be understood that what has been described herein is intended to be illustrative only, and is not intended to limit the scope of the invention.
