SUMMARY OF TH INVENTION Thus, it is an object of the invention to provide a space divider which is of simple, inexpensive one-piece construction, and is capable of being readily set up by a simple manual or mechanical manipulation.

It is a further object of the invention to provide a blank for an improved space divider which may be formed on conventional high-speed scoring, slotting, and cutting equipment with a minimal amount of material waste.

It is a still further object of the invention to provide an improved space divider which assumes a thin, flat condition when in a collapsed state. I

It is a still further object of the invention to provide an improved space divider wherein the walls thereof may extend the full height of the container in which said divider is disposed and thus enhance the top-tobottom strength of the container.

Further and additional objects will appear from the description, accompnaying drawings, and appended claims.

In accordance with one embodiment of the invention, a space divider is provided which is formed from a single blank of sheet material and is adpated to be disposed within the interior of a shipping container or the like. The divider includes a pair of bottom panels which are adapted to overlie the bottom of the container.

The bottom panels are separated from one another by an upright, transversely extending partition panel. The partition panel also separates pairs of side panels which are foldably connected to opposite peripheral portions of the bottom panels. The side panels, which are disposed on the corresponding peripheral segments of the bottom panels, are interconnected by connecting panels. Each connecting panel is formed of a pair of foldably connected sections. One section is foldably connected to one side panel and is separated from the partition panel by a cut. The second section is foldably connected to a side panel disposed on the opposite side of the partition panel. In addition, the second section is connected to the partition panel by a substantially diagonally extending foldline. The sections of each connecting panel are folded realtive to one another so as to sandwich therebetween a portion of the partition panel.

DESCRIPTION For a more complete understanding of the invention, reference should be made to the drawings wherein:

FIG. 1 is a top plan view of a blank for one form of the improved space divider.

FIG. 2 is a perspective view of the blank of FIG. 1 in a partial set-up condition.

FIG. 3 is a top view of the blank of FIG. 1 in a fully set-up condition.

FIG. 4 is a top perspective view of one form of the improved space divider shown assembled within a shipping container, the latter being outlined in dash-dot lines.

Referring now to the drawings and more particularly to FIG. 4, one form of the improved space divider 10 is shown disposed within the interior of a conventional shipping container 11, or the like. In the illustrated embodiment, the space divider 1 0 cooperates with the walls of the container to form six compartments I-VI of substantially like configuration. Modifications of the basic divider design will be described more fully hereinafter wherein the number of compartments can be increased by increments of three.

The improved divider 10 is formed from a single blank 12 of suitable sheet material such as, for example, double-faced corrugated fiberboard. As seen in FIG. 1, the blank 12 has a substantially rectangular configuration and may be readily formed by highspeed, automatic cutting, scoring, and slotting machinery with but a minimum of material waste being produced. Blank 12 includes a centrally disposed partition panel 13, a first bottom panel 14, a second bottom panel 15, a pair of

first side panels

16 and 17, and a pair of

second side panels

18 and 20. The

first side panels

16 and 17 are foldably connected to opposite peripheral segments of the first bottom panel 14 and in a like manner, the

second side panels

18 and 20 are foldably connected to the second bottom panel 15. When the blank is set up to form the divider, the

panels

14, 16, and 17 are separated from

panels

15, 18, and 20 by the partition panel 13, see FIGS. 3 and 4. As seen in FIG. 1, blank 12 also includes a pair of connecting

panels

21 and 22 which are disposed on opposite sides of panel 13. Each connecting

panel

21 or 22 includes a pair of foldable sections 21a-21b and 22a-22b. Sections 21a and 22a are of like configuration and each has a peripheral segment thereof connected by a

foldline

23 or 24 to the adjacent

first side panel

16 or 17. Each

foldline

23 or 24 may be interrupted by an elongated slit 23a or 24a or other suitable means, thereby reducing the folding resistance and thus facilitating setting up of the blank. A portion of the opposite peripheral segment of section 21a or 22a is connected to the

respective section

21b or 22 b by a

foreshortenecl foldline

25 or 26. The remainder of the peripheral segment of section 21a or 22a, which is aligned with

foldline

25 or 26, is separated by slits 27 and 28 from

adjacent shoulders

13a and 13b formed on the partition panel 13. The inner peripheral segment of each section 21a and 22a is separated from the center portion 310 of the partition panel 13 by slits 30. A gap 31 is formed between the end edge of the panel center portion 13c and! first bottom panel Each of the

second sections

21b and 22b of the connecting

panels

21 and 22 has a peripheral segment thereof connected by a

foldline

32 or 33 to the adjacent

second side panel

18 or 20. As in the case of foldlines ,23 and 24,

foldlines

32 and 33 may be interrupted by elongated slits 32a and 33a or other suitable means so as to reduce folding resistance. The inner peripheral segment of

sections

21b and 22b are connected to the

shoulders

13a and 13b, respectively, by diagonally extending

foldlines

34 and 35. Foldline 34 interconnects the inner ends of

foldlines

25 and 32, and foldline 35 interconnects the inner ends of

foldlines

26 and 33.

The second bottom panel 15, in the illustrated blank, is connected by foldline 36 to the lower edge of the partition panel 13; such foldling connection, however, is not essential.

The blank 12 may be set up to form the divider by a simple manual folding manipulation, which is partially shown in FIG. 2. To set up the blank, the latter is grasped from the underside along the margin thereof in the vicinity of foldlines and 26. The thumbs of the hands are simultaneously pressed downwardly on the

foldlines

25 and 26 causing the sections 21a-21b and 22a-22b to be folded inwardly. Simultaneous with the inward folding of the sections of the connecting panels, the side panels are folded to upright positions relative to the

bottom panels

14 and 15. Because of the gap 31 and slits 27, 28, and 30, the partition panel 13 will automatically assume an upright position with the shoulder portions 13a and b of the partition panel becoming sandwiched between the folded sections of the connecting panels, see FIG. 3.

In order to return the space divider to a flat condition, as shown in FIG. 1, merely requires'the side panels to be folded outwardly relative to the bottom panels.

If, for example, three additional compartments are required to be formed in a container (a total of nine compartments), a modified blank, not shown, would be utilized which consists of the combination of a first blank section like that shown in FIG. 1 and a second blank section connected to the bottom edge of the first blank section. The second blank section would have a configuration similar to the first blank section, except that

panels

16, 14, and 17 would be eliminated. Further modifications of the blank, shown in FIG. 1, may also be made by changing the size and shape of the various panels forming same.

Thus, it will be seen that a simple, compact, and unitary space divider has been provided which can be readily set up when required. The divider can be modified so as to be effectively used with a variety of containers, or the like.
