Description: A POLYGONAL CONTAINER BACKGROUND OF THE INVENTION The present invention relates generally to polygonal containers and more particularly to polygonal containers having interlocking container sides and bottom assemblies which f rther include a bottom reinforcement means, whereby the resulting polygonal container is one of exceptional strength and stability. In the prior art, various polygonal container struc- tures have been proposed for containing various types of goods. A variety of different materials, including paper board, fiber board, and various corrugated materials have been proposed. Although many of such prior art polygonal containers have been generally acceptable for general and/or limited use, typically such prior art polygonal containers • have been less than optimal in performance and especially in their weight-supporting capacity. Also, the prior art containers frequently have utilized bottom structures which, rather than representing a point of strength to the container, have resulted in a feature of greatest relative weakness. Moreover, many such prior art containers have resulted in the contained material being supported directly by the ground, thereby frequently resulting in damage to the contents thereof. In view of the above and other difficulties asso¬ ciated with the prior art, it is an object of the polygonal container of the present invention to provide a container which has increased weight-supporting capacity. It is also an object of the polygonal container of the present invention to provide a container having a bottom assembly of greatly increased strength. It is an additional object of the polygonal container of the present invention to provide a container having an interlocking container sides assembly and an interlocking con- tainer bottom assembly, which further includes bottom rein¬ forcement means corresponding generally in shape and size to a polygonal bottom panel and disposed'into intimate proximity thereto to reinforce and strengthen the bottom panel. It is a further object of the polygonal container of the present invention to provide bottom reinforcement means which may be foldably formed from a unitary blank of material. It is yet a further object of the polygonal contain¬ er of the present invention to provide a polygonal container including stacking means and stacking cavity means to fit the containers substantially snugly together for stability of stacking. ' It is a yet further additional object of the poly¬ gonal container of the present invention to provide a con¬ tainer top including a handle grip, reinforcement associated therewith for strength thereof during grasping and handling of the polygonal container. It is also a further object of the polygonal con¬ tainer of the present invention to provide a hingedly con¬ nected container lid which may be interlockingly and remov- ably disposed with respect to the container sides assembly. These and other objects and advantages of the poly¬ gonal container of the present invention will become apparent to one of ordinary skill in the art in view of the following specification. SUMMARY OF THE PRESENT INVENTION In the polygonal container of the present invention there is provided a container which is polygonal in shape and which has separate container sides and container bottom assemblies adapted for interlocking engagement therebetween. The container sides assembly, in general, preferably comprise a unitary blank of relatively rigid, but foldable, material having a plurality of generally rectangular side panels hing¬ edly interconnected to form an enclosure defining the sides of the polygonal container. The container sides assembly includes a plurality of lower edge flaps hingedly connected to the lower edge of the rectangular side panels and adapted O PI for folding upwardly and inside the enclosure to interlock- ingly receive corresponding elements of the container bottom assembly. The container bottom assembly comprises a polygonal bottom panel having sides equal in number to the rectangular side panels of the container sides assembly and is of such a size to fit snugly within the container sides assembly when in assembled configuration thereby forming the container bottom. The container bottom assembly further includes a plurality of ear members equal in number to said number of sides of the polygonal bottom panel. Each ear member is hingedly connected to a side of the polygonal bottom panel and is downwardly extending therefrom for operative engage¬ ment with the upwardly extending lower edge flaps of the container sides assembly. A bottom reinforcement means which corresponds gen¬ erally in shape and size to the polygonal bottom panel is disposed in intimate proximity to the polygonal bottom panel to reinforce and strengthen the polygonal bottom panel. The bottom reinforcement means may preferably comprise an insert of hard, resilient material, may be formed from a block of styrofoa material, may be formed by a spirally wound strip of material, or may be formed from a unitary blank of corru¬ gated material folded to form the bottom reinforcement means. The polygonal container of the present invention may further include any of several lid assemblies therefor. One such preferred lid assembly is hingedly connected to one of the rectangular side panels at a top edge thereof. This preferred lid assembly comprises a polygonal top panel of the size and shape generally corresponding to the opening at the top of the enclosure formed by the polygonal container. A plurality of side panels extend downwardly from the poly¬ gonal top panel to form interlocking sides of the lid assem¬ bly such that the container is securely capped at each poly- gonal side of the container opening. The container lid assem¬ bly further preferably includes a lid securement means for releaseably interlocking the lid assembly with the container sides assembly.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS Polygonal containers in accordance with the princi¬ ples and teachings of the present invention include a con¬ tainer sides assembly and a container bottom assembly which is adapted for interlocking engagement with the container sides assembly at the lower portion thereof to form the con- tainer bottom. The container sides assembly comprises a plurality of generally rectangular side panels interconnected to form an enclosure defining the sides of the polygonal con¬ tainer. A plurality of preferably slotted lower edge flaps are hingedly connected to the lower edge of the rectangular side panels and are adapted for folding upwardly and inside the enclosure to interlockingly receive corresponding ele- ments from the container bottom assembly. The container bottom assembly includes a polygonal bottom panel having sides equal in number to those of the rectangular side panels and is of such a size as to snugly fit within the container sides assembly when it is in assem¬ bled configuration, thereby to form the container bottom. A pluralit of ear members equal in number to the number of sides of the polygonal bottom panel are each hingedly connect ed to a side of the polygonal bottom panel and extend down- wardly therefrom for operative engagement with the upwardly extending lower edge flaps of the container sides assembly. A bottom reinforcement means for the container bottom is pro¬ vided to correspond generally to the size and shape of the polygonal bottom panel and to be disposed into intimate proximity to the polygonal bottom panel to reinforce and strengthen the polygonal bottom panel. Such bottom reinforce ment means preferably is disposed in contact with and is fix¬ edly secured to the polygonal bottom panel at the underside thereof. Means for fixably securing the bottom reinforcement means may includes staples, glue, or other means known to one skilled in the art. The bottom reinforcement means may also be maintained in intimate proximity to the polygonal bottom panel by means of an interference fit between the bottom reinforcement means and the plurality of lower edge flaps when the lower edge flaps are folded upwardly and in¬ side the container enclosure to interlockingly receive the ear members of the container bottom assembly. ' The bottom reinforcement means may preferably com¬ prise an insert of a hard, resilient material, such as metal, plastic, fiberboard, or other materials. An insert of styro- foam material may also be utilized. An alternative preferred bottom reinforcement means may comprise an insert of a ver¬ tically corrugated material having a multiplicity of corruga¬ ted ribs extending normal to the polygonal bottom panel such as in a vertical honeycomb configuration. The multiplicity of corrugated ribs covers substantially one face of the poly¬ gonal bottom panel to support and reinforce the entirety OMPI thereof and especially against a downwardly compressive force. Further alternative bottom reinforcement means may comprise a preferably unitary blank having a polygonal cen¬ tral bottom reinforcement panel corresponding generally to the size and shape of the polygonal bottom panel. A plural¬ ity of supplemental reinforcement panels equal in number to the number of polygonal sides of the polygonal central bot¬ tom reinforcement panel may be attached thereto by means of hinges disposed therebetween, thereby permitting reflexively folding a first supplemental bottom reinforcement panel and the others in sequence to form a multi-layered insert having a substantial thickness. The length of the hinge means be¬ tween the respective supplemental bottom reinforcement panels and the polygonal central reinforcement panel preferably in- creases proportionally from the first supplemental bottom panel to the last supplemental reinforcement bottom panel, whereby the multi-layered insert once folded will tend to remain in such multi-layered configuration without the appli¬ cation of substantial external force. The polygonal bottom reinforcement panel, the supplemental bottom reinforcement panel, and the hinge means may preferably comprise a horizon¬ tally corrugated material having corrugated ribs disposed generally parallel to each other uniformly along the length of the unitary panel. The result of such a structure is that when the supplemental bottom panels are reflexively folded to form the multi-layered insert configuration, the corrugat¬ ed ribs on adjacent supplemental bottom panels overlap each other at an acute angle to form a structure having substan¬ tially uniform flex resistance to bending in any lateral dir- ection. This preferred embodiment of a bottom reinforcement insert preferably has sides of less than seven (7) in number with the hexagonal shape being preferred. A further alternative embodiment of a bottom rein¬ forcement means includes a plurality of hingedly interconnect- ed supplemental bottom support panels of substantially the same size and shape as the polygonal bottom panel, at least one of which supplemental bottom support panels is hingedly connected to the bottom support panel at a polygonal side thereof for reflexively folding onto the bottom support panel, thereby to provide reinforcement thereto. The supple¬ mental bottom support panels are reflexively folded on the underside of the polygonal bottom container in preferred em¬ bodiments. At least one such supplemental bottom support panel is hingedly connected to each of a pair of opposing polygonal sides of the polygonal bottom support panel. Such opposing connected supplemental bottom support panels are preferably hingedly connected to the polygonal side of the polygonal bottom panel near the juncture of the connected polygonal side with the adjacent polygonal side of the poly¬ gonal bottom panel. In such embodiments, the ear members of the container bottom assembly are connected to such polygonal bottom panel interior of the connection thereof with the supplemental bottom support panel. Also in such preferred embodiments, at least a first supplemental bottom support panel is foldable along a fold line dividing such first sup¬ plemental bottom support panel into equal parts for reflexive ly folding at least such first supplemental bottom support panel onto itself, whereby the container bottom is disposed into folded configuration. In such a configuration each such opposing first supplemental bottom support panel reinforces one-half of the polygonal bottom panel. A second supplementa bottom support panel having such fold lines thereon is pre¬ ferably provided for hinged connection to the oppositely dis¬ posed first supplemental bottom support panel for additional reinforcement to the polygonal bottom panel. In other alternative preferred embodiments, the re- inforcement means may comprise a strip of flexible material which is spirally wound to form a cylindrical body having a diameter of such size and shape as to fit snugly with respect to the lower edge flaps of the container sides assembly when the container sides assembly is disposed in interlocking en- gagement with the container bottom assembly. Such polygonal containers may have from twelve (12) to twenty-four (.24) sides, although a lesser number of sides, such as the hexa- _ . OMP gonal shape, is meant to be included within the scope of the present invention. The polygonal container of the present invention may further include a stacking cavity at the bottom thereof bounded by the bottom reinforcement means lower surface and the lower edge flaps. Corresponding means for.covering the opening at the top of the polygonal container of the enclo¬ sure may include thereon a mating stacking means projecting above the surface thereof for engagement with the stacking cavity of another polygonal container. The stacking means and stacking cavity are preferably of such corresponding size and shape to fit substantially snugly together, whereby stable stacking of containers may be maintained. One preferred embo¬ diment for such stacking means includes at least two polygonal stacking panels hingedly connected at polygonal sides thereof for reflexively folding together into intimate contact of the respective faces thereof to form a stacking block of sub¬ stantial thickness for stacking engagement with the stacking cavity. Alternatively, a solid block of material, such as styrofoam, may be utilized. A polygonal container of the present invention may further include, in conjunction with a lid assembly having an aperture therein, a handle grip reinforcement means for use when the container is manually grasped and handled. Such handle grip reinforcement means preferably comprises a grip member which is hingedly connected at the proximal portion thereof to the top edge of the rectangular side panel form¬ ing the proximate polygonal side and projecting laterally across the opening to a position adjacent the lid aperture. Such handle grip reinforcement grip member is preferably reflexively foldable at a central portion thereof and has a mating tab for interlocking engagement with a horizontal slot means contained in the corresponding rectangular side panel top portion. The polygonal container of the present invention may also include a lid assembly hingedly connected to one of the rectangular side panels at the top edge thereof. The lid as- sembly preferably comprises a polygonal top panel of suffi¬ cient size and shape to cover the opening at the top of the enclosure formed by the polygonal container. The top panel is hingedly connected at a first lid polygonal side thereof to the top edge of one of the rectangular side panels to form a first, hinged polygonal lid side. A plurality of lid side panels, being one less in number than the number of poly gonal sides of the polygonal container, are each hingedly connected at a proximal portion thereof to a polygonal side of the polygonal top panel. Each lid side panel is dispos¬ able downwardly when in assembled configuration into contact¬ ing relationship with the top portion of the corresponding rectangular top panels of the container sides assembly to close the opening at the top of the enclosure formed by the polygonal container. A pair of the lid side panels are con¬ nected to second and third lid polygonal sides adjacent to the first, hinged polygonal lid side. Each of the second and third lid polygonal sides has a free side edge and abut¬ ting side edges. The remainder of the lid side panels have two opposed abutting side edges when the lid side panels are disposed downwardly in an assembled configuration. A plurality of interlocking panels, being two less in number than the number of polygonal sides of the polygon¬ al container, are each hingedly connected to an opposed side edge of a corresponding lid side panel. Each side panel bears a locking protrusion thereon. Each of a plurality of securement panels, being three less than the number of sides of the polygonal container, is hingedly connected at its proximal end to the distal end of one of the remainder of the lid side panels. Each such securement panel has a lock¬ ing slit disposed at the hinged connection with the corres¬ ponding lid side panel for mating engagement with such lock¬ ing protrusion, thereby to secure the lid in assembled con¬ figuration. The unitary lid and container sides assembly pre¬ ferably further includes lid securement means for removably securing the assembled lid atop the assembled container sides assembly. The lid securement means preferably comprises a securement release access aperture disposed in at least one of the remainder of the lid side panels to form an apertured lid side panel. A lid securement flap is hingedly disposed at the top edge of the rectangular side panel corresponding to each of the apertured lid side panels. Each of the lid securement flaps is foldable outwardly and downwardly for locking engagement with the corresponding securement panel distal edge. The result .of such structure is that, when the lid assembly is in assembled configuration, it may be disposed over the top portion of the container sides assembly to slide over and lockingly engage the lid securement flap. Thereafter, the lid securement flaps may be manually pressed and disposed slightly inwardly through the securement release access aperture to disengage the lid securement flaps from the securement panel distal edge for removing the cover. The polygonal container of the present invention may have a polygonal lid provided for use in connection therewith. The polygonal lid includes a polygonal top panel having a number of polygonal sides the same in number as the number of sides of the corresponding polygonal container. The polygonal top panel is of such size and shape to correspond substantially to the size and shape of the opening of the top of the poly¬ gonal container. A plurality of lid side panels are provided, being the same in number as the number of sides of the poly¬ gonal container, each having oppositely disposed upper and lower edges and opposed side edges. Each lid side panel is hingedly connected at a proximal edge thereof to a polygonal side of the polygonal top panel for foldable disposition downwardly and substantially normal to the polygonal top panel to dispose adjacent lid side panels in substantially contacting relationship at the opposed sides thereof. Also included are means for maintaining the opposed sides in substantially contacted relationship. A securement panel is hingedly connected to the distal edge of each lid side panel with the securement panel being reflexively fold¬ able upwardly to dispose each securement panel into intimate proximity to the interior surface of each of the lid side panels. Further included are lid securement means for re¬ movably securing the polygonal top on the assembled container The lid securement means includes a securement release ac- cess aperture disposed on at least one of the lid side panels to form an apertured lid side panel. A lid securement flap is hingedly disposed at the top edge of the rectangular side panel corresponding to each of the apertures of the side panels. Each lid securement panel is foldable outwardly and downwardly for locking engagement with the corresponding securement panel distal edge. The result is that when in assembled configuration the lid assembly may be disposed over the top portion of the container sides assembly to slide over and lockingly engage the lid securement flap. The polygonal container of the present invention may preferably have lower edge flaps and corresponding engaging ear members which are equal in number. The number of sides of the polygonal container may be three or greater, prefer¬ ably six in some embodiments and twelve to twenty-four in others. The lower edge flaps of the container sides assembly are preferably separated from each other by a slit extending from the lower extremity of the container sides assembly to the corresponding rectangular side panel, thereby to render the lower edge flaps more easily foldable upwardly in en- gagement with the ear members of the container bottom assem¬ bly. Such slits separating the lower edge flaps may perfer- ably extend from the lower extremity of the container to a point preferably disposed between two adjacent rectangular side panels to permit greater ease in folding the lower edge flaps upwardly. The container sides assembly may further preferably include a longitudinally extending side flap hingedly dis¬ posed therefrom, with the panel disposed at the opposite side of the blank having a free edge for receiving the longitudi- nally extending side flap, thereby to form the enclosure of the polygonal container. OM?I The polygonal container of the present invention may also include in preferred embodiments a cap assembly for covering the opening at the top of the enclosure formed by the polygonal container. The cap assembly preferably includes at least one polygonal cover panel hingedly attached at a first polygonal side thereof to the top edge of a first rec¬ tangular side panel. The polygonal cover panel is foldable generally normal to the first rectangular side panel for covering the top opening of the polygonal container. A poly- gonal cover hinge is foldably attached to the polygonal cover panel at a second polygonal side which is adjacent to the first polygonal side. The polygonal cover hinge is also fold¬ ably attached at the top edge of a second rectangular side panel which, is adjacent to the first rectangular side panel. The polygonal cover hinge is wedge-shaped to span the angle between the second polygonal side of the polygonal cover panel and between the top edge of the second rectangular side panel, the angle being generally bisected by a fold line thereby forming the hinged structure. The functioning of that structure is such that, when the polygonal cover panel is disposed normal to the first rectangular side panel, the second polygonal side of the polygonal cover panel is dis¬ posed onto the top edge of the second rectangular side panel to cover the opening at the top of the enclosure formed by the polygonal container. In an alternative preferred embodi¬ ment, at least two polygonal cover panels and accompanying polygonal cover hinges may be provided for overlapping dis¬ position when in the folded position normal to the corres¬ pondingly rectangular side panels. The polygonal cover panels may be separated by two intervening rectangular side panels. Supplemental cover panels of lesser size than the polygonal cover panels may be provided for supplemental support to the polygonal cover panels when in such folded and covering relationship. Referring now to the drawing wherein common members are for the most part utilized for common elements and to Figs. 1 and 2 in particular, the polygonal container of the present OMPI /., WIPO - invention shown generally at 100 includes a container sides assembly generally 102 and a container bottom assembly gene¬ rally 104 which is adapted for interlocking engagement with container sides assembly 102 at the lower portion 103 thereo to form the container bottom. Container sides assembly 102 comprises a plurality of generally rectangular side panels 106a-f (see Figs. 9 and 12) interconnected to form an en¬ closure 108 defining the sides of polygonal container 100. A plurality of preferably slotted, lower edge flaps llOa-f are hingedly connected to the lower edge 112 of rectangular side panels 106a-c and are adapted for folding upwardly and inside enclosure 108 to interlockingly receive corresponding elements from container bottom assembly 104. Container bot¬ tom assembly 104 includes a polygonal bottom panel 114 havin sides equal in number to those of the rectangular side panel 106a-f and is of such a size as to snugly fit within the con tainer sides assembly 102 when it is in assembled configura¬ tion, thereby to form the container bottom. As shown in Fig. 8, a plurality of ear members 116a-f equal in number to the number of sides of polygonal bottom panel 114 are each hinge ly connected to a side of polygonal bottom panel 114 and ex¬ tend downwardly therefrom for operative engagement with the upwardly extending lower edge flaps llOa-f of container side assembly 102. A bottom reinforcement means generally 118 for the container bottom is provided to correspond generally to the size and shape of polygonal bottom panel 114 and to be disposed into intimate proximity to polygonal bottom pane 114 to reinforce and strengthen polygonal bottom panel 114. Such bottom reinforcement means 118 preferably is disposed i contact with and is fixably secured to polygonal bottom pane 114 at the underside 120 thereof as shown in Fig. 4. Means for fixably securing the bottom reinforcement means may in¬ clude staples, glue or other means known to one skilled in the art. Bottom reinforcement means 118 may also be main- tained in intimate proximity to polygonal bottom panel 114 by means of an interference fit between bottom reinforcement means 118 and the plurality of lower edge flaps llOa-f when _O PI lower edge flaps llOa-f are folded upwardly and inside the container enclosure as shown in Figs. 4 and 6 to interlock- ingly receive ear members llβa-f of container bottom assembly 1Q4. Bottom reinforcement means 104 may preferably com¬ prise an insert of a hard, resilient material, such as metal, plastic, fiberboard, or other material. An insert of styro- foam material may also be utilized. As shown in Figs. 2, 4, and 11, an alternative preferred bottom reinforcement means 118 may comprise an insert of a vertically corrugated mater¬ ial having a multiplicity of corrugated ribs 122 extending normal to polygonal bottom panel 114 such as in a vertical honeycomb configuration. The multiplicity of corrugated ribs 122 covers substantially one face of polygonal bottom panel 114 to support and reinforce the entirety thereof and especially against a downwardly compressive force. As shown in Figs. 13-17, further alternative bottom reinforcement means 125 may comprise a preferably unitary blank 124 as shown in Fig. 17 having-a polygonal central bot- torn reinforcement panel 126 corresponding generally to the size and shape of the polygonal bottom panel 114. A plural¬ ity of supplemental reinforcement panels 128a-f equal in num¬ ber to the number of polygonal sides of the polygonal central bottom reinforcement panel 126 may be attached thereto by means of hinges 130a-f disposed therebetween (see Fig. 17) thereby permitting reflexively folding a first supplemental bottom reinforcement panel 130a and the others 130b-f in sequence to form a multi-layered insert 131 having a substan¬ tial thickness. The length of hinge means 13Qa-f between the respective supplemental bottom reinforcement panels 128a-f and polygonal central reinforcement panel 126 preferably increases proportionally from first supplemental bottom panel 128a to the last supplemental reinforcement bottom panel 128f, where¬ by the multi-layered insert 125 once folded will tend to re- main in such multi-layered configuration without the applica¬ tion of substantial external force. Polygonal bottom rein¬ forcement panel 126, supplemental bottom reinforcement panel 128a-f and hinge means 130a-f may preferably comprise a hori zontally corrugated material having corrugated ribs 132 dis¬ posed generally parallel to each other uniformly along the length of unitary panel 218. The result of such a structure is that when the supplemental bottom panels 128a-f are re¬ flexively folded in such numbered sequence to form multi- layered insert 131, corrugated ribs 132 on adjacent supple¬ mental bottom panels overlap each other at an acute angle to form a structure having substantially uniform flex resistanc to bending in any lateral direction, as illustrated, by grain direction lines 1-3-6, and 2-5 of Fig. 16. This preferred embodiment of a bottom reinforcement insert 125 preferably has sides of less than seven (7) in number with the hexagona shape being preferred as illustrated in Figs. 13-17. A further laternative embodiment of a bottom rein¬ forcement means 134 is shown in Figs. 18-21 and includes a plurality of hingedly interconnected supplemental bottom support panels 136a-f of substantially the same size and shape as polygonal bottom panel 114, at least one of which supplemental bottom support panels (136d, for example) is hingedly connected directly to bottom support panel 114 at a polygonal side 138 thereof for reflexively folding onto the bottom support panel 114 as shown in Fig. 19, thereby to provide reinforcement thereto. Supplemental bottom sup- port panels 136a-f are reflexively folded on the underside 138 of polygonal bottom container 114 in preferred embodi¬ ments. At least one such supplemental bottom support panel (136c and 136d, for example), is hingedly connected to each of a pair 138, 140 of opposing polygonal sides of polygonal bottom support panel 114. Such opposing connected supple¬ mental bottom support panels 136c and 136d are preferably hingedly connected to polygonal sides 138, 140 of polygonal bottom panel 114 near the juncture of the connected poly¬ gonal side with the adjacent polygonal side of polygonal bottom panel. In such embodiments, ear members 116a, 116d of container bottom assembly 104 are connected to such poly¬ gonal bottom panel 114 interior of the connection thereof with supplemental bottom support panels 136d and 136c res¬ pectively. Also in such preferred embodiments, at least a first supplemental bottom support panel 136d is foldable along a fold line 142 dividing such first supplemental bot- torn support panel 136d into equal parts for reflexively folding at least such first supplemental bottom support panel 136d onto itself, whereby the container bottom is dis¬ posed into folded configuration to form an insert of substan¬ tial thickness as shown in Fig. 21. In such a configuration each such opposing first supplemental bottom support panel 136c and 136d reinforces one-half of the polygonal bottom panel 114.
