DETAILED DESCRIPTION

(12) FIG. 1 illustrates a known embodiment of a divider box. As was described above, such designs require partition sections 10 that extend past the walls of the outer partitions formed by those partition sections. These extensions 12 result in an unused portion of the enclosure. Not only does this reduce the usable space within the divider box, it doesn't provide any support or strength to the divider box walls.

(13) The disclosed divider box assembly may be useful in shipping individual component parts in individual compartments so as to prevent damage by the parts, for example, by bumping against each other during shipment. The disclosed divider box assembly can be shipped in a relatively flat, folded down configuration and then unfolded at the plant for stuffing with parts. The entire volume of the divider box may be used for storing component parts inasmuch as compartments fill the entire interior volume of the divider box.

(14) Referring to FIG. 2, a divider box assembly according to an embodiment of the invention 20 may be comprised of a plurality of longitudinal panels 22 and transverse panels 24. FIG. 3 illustrates an embodiment of a longitudinal panel 24. As illustrated, the longitudinal panel comprises a series of slots 30 extending from the bottom of the panel, upward to about half the distance of the panel. FIG. 4 illustrates an embodiment of a transverse panel 22. The transverse panel has series of slots extending downward from the top edge of the panel. Referring again to FIG. 2, these panels may be placed at right angles to one another and the slots inserted into each other so as to form the divider assembly of FIG. 2. As is illustrated in FIG. 3, each longitudinal panel may also comprise tabs 32, formed along bend lines 34 located at the ends of the panel. Similarly, a transverse panel may also comprise tabs 42 located similarly along bend lines 44 at the ends of the panel. Referring to FIG. 5 which illustrates a transverse panel 22, the tabs 42 may be bent at an approximately 90 degree angle from the panel. The number of slots (30 and 40) and the number of longitudinal panels 24 and transverse panels 22 show in the figures references herein is by way of illustration and not intended to be a limitation of the invention.

(15) As is illustrated in FIG. 6, a divider assembly 50 may be formed from a plurality of longitudinal and transverse panels. As also illustrated an outer partition may be formed by abutting the transverse panel tabs 42 against an adjacent transverse panel bend line 44. Tape 52 or a similar material may be used to secure these tabs 42 to the adjacent panel 22.

(16) While the assembly of FIG. 6 may provide sufficient strength for many applications, additional panels may provide increased strength to resist downward forces that result from stacking or rough handling. Such an embodiment is illustrated in FIGS. 7A and 7B. As is shown, one or more divider assemblies 600 may be combined with external panels 602, 604, 606, and 608 to form a divider box 610. As is illustrated in FIG. 7B, such panels (602-608) may be affixed to the outer surfaces of the divider assembly using glue, tape, staples, or similar methods of affixing the external panels to the divider assembly. In certain embodiments of the invention, the external panels may be comprised of high strength materials, including, but not limited to corrugated fiberboard, plastic sheet, corrugated plastic sheet, and wood.

(17) Referring to FIG. 8, the divider box 610 described above may be combined with a bottom cover 630 and a top cover 640 to produce a complete enclosure. In certain embodiments, the top or bottom cover may be affixed to the divider box to provide additional strength and resistance to deformation of the divider box.

(18) In circumstances in which additional structural strength is required, an embodiment of the invention may comprise a plurality of divider boxes 610 formed from divider assemblies 600 and exterior panels (602-608). Such an embodiment is illustrated in FIG. 9, where a first divider box 910 and second divider box 920 may be placed on a bottom cover 930 to form a divider box assembly 940. Such an assembly may be comprised of a number of divider boxes where additional strength may be obtained as the result of the additional strength provided by external panels of each divider box forming internal partitions of the divider box assembly. An example of such an internal partition is shown at 950. As an example, four divider boxes may combined to produce an additional strength partition between each box. The result may be a divider box assembly that has increased resistance to forces exerted by the stacking of multiple boxes. In such embodiments, the number of longitudinal panels 24 and transverse panels 22 may be reduced to produce fewer compartments 960. As a result, more divider boxes 902 may be required to produce the same number of compartments. The result would be a greater number of higher strength internal partitions 950 resulting in a divider box assembly 940 that has a much greater resistance to forces exerted by the stacking of divider boxes with a relatively small increase in weight and size of the divider box assembly 940.

(19) Materials of construction for forming the divider boxes can be a paperboard or corrugated paperboard material, such as, for example, cardboard, pasteboard, fiberboard, corrugated plastic sheets, or the like. However, any material having the necessary strength and rigidity for the particular application envisioned is suitable. As to the preferred paperboard materials, it will be appreciated that the wall construction thereof, i.e., single-ply, double-ply, or higher, may be varied depending upon the application. The divider boxes and divider box assemblies will be described in particular reference to the use of corrugated paperboard; however, such description is illustrative and not a limitation on the present disclosure.

(20) While the divider boxes have been described with reference to various embodiments, those skilled in the art will understand that various changes may be made and equivalents may be substituted for elements thereof without departing from the scope and essence of the disclosure. In addition, many modifications may be made to adapt a particular situation or material to the teachings of the disclosure without departing from the essential scope thereof. Therefore, it is intended that the divider box not be limited to the particular embodiments disclosed. Also, all citations referred herein are expressly incorporated herein by reference.
