FIGQIZ INVENTOR. AUGUSTINE A- SOUZA BY flwaq WM ATTORNEYS PRODUCE SHIPPING CONTAINER BACKGROUND OF THE INVENTION The present invention relates in general to packing and shipping containers, and in particular, to those containers having expandable sides and corner members for facilitating nesting of the containers prior to packing. When such containers are packed, the sides and corners expand outwardly and assume a generally normal orientation relative to a bottom member. Known containers of this type conventionally comprise relatively thick side walls and corner members of sufficient strength and rigidity to support and resist twisting when a number of similar type containers are vertically stacked one upon another.
Due to the great number of such containers required in commercial operations, it is imperative that the weight and material costs be reduced to a minimum while maintaining and, if possible, improving the ability of an individual container to support its own load, as well as the weight of other loaded containers stacked vertically thereon.
SUMMARY OF THE INVENTION A principal object of the present invention is a container for use in packing and shipping which is adapted for compact nesting and is less expensive, lighter, stronger and more stable when stacked with other containers of like size and shape than containers heretofore available.
In accordance with the present invention, there is provided a container comprising a plurality of sidewalls having an inwardly directed draft of a few degrees from top to bottom. Each of the sidewalls is joined at its respective adjacent edge to a corner member by means of a pair of accordian-type hinging members. A dome shaped ribbed bottom member is attached at its edges directly to the lower edges of the sidewalls and to each corner member by a similar accordian-type hinging member. The accordian-type hinging members along the sides and bottom edges of the corner members permit the corner member to assume an inwardly directed draft of a few degrees from top to bottom to facilitate nesting prior to packing. During packing, the accordian-type hinging members permit the corner members to extend outwardly beyond the sidewalls to a position whereat the walls of the corner members assume an outwardly directed draft of 1 from top to bottom. The draft assumed by the walls of the corner members during packing, called the stacking configuration, is found to permit the load of stacked containers to be removed from the sidewalls and carried by the corner members. A cover member comprising a domed portion corresponding to the domed portion of the bottom member is provided for engaging bifurcated cover locking slots provided in the upper edges of two opposing sidewalls. The comers of the cover member and the moveable corner members are further provided with grooves and corresponding beads which are adapted to mate and engage in an interlocking male-female relationship when one container is stacked on another. The domed portions of the cover and bottom member together with the interlocking grooves and beads facilitate stacking and reduce slipping and twisting during shipping and together with the draft assumed by the corner members in a stacking configuration results in a reduction in material and attending costs from that required for known containers complying with equivalent accepted standards for structural integrity.
These and other objects, advantages and features of the present invention will be apparent to those skilled in the art from the detailed description and accompanying drawings hereinafter described:

DETAILED DESCRIPTION Referring to FIG. 1, there is provided in accordance with the present invention, as indicated generally, a container 1. Container 1 comprises a plurality of sidewalls or curtains 2-5 joined along their respectiveadjacent edges to form an integral unit by a plurality of moveable members 12-15. Each of sidewalls 12-15 is provided to have an inwardly directed draft from topto bottom of a few degrees, typically 4. In the illustrated preferred embodiment, moveable members 12-15 each comprise a pair of mutually perpendicularly orientated plane walls 8 which serve as corner members for container 1. A domed bottom member 16 is provided attached to the lower edges of sidewalls 2-5 and to corner members 12-15. Sidewalls 2,4 comprise, as indicated generally, an M-shaped frame 22, 23 respectively, for additional strength as each of sidewalls 2,4 as well as sidewalls 3,5 are permitted to be made of relatively thin material as of 0.06 inches thick as a result of the construction of corner members 12-15. A central portion 6,7 of the upper edges of sidewalls 2,4 is reduced in height relative to sidewalls 3,5 to form in conjunction with a pair of horizontal members 20,21 of M-shaped frames 22, 23 a bifurcated cover lock slot 24,25, respectively. As is conventional for containers used in carrying produce, there is provided in the lower portions of sidewalls 2-4 a plurality of air vents 26. Referring to the upper edges of each of sidewalls 2 and 4, 3 and 5, and corner members 12-15, there is provided a plurality of horizontally extending outwardly directed lips 27-29 respectively. A collar 31 extends vertically from the outer edge of each of lips 27-29. A corner groove 32 is provided in lip 28 of each of comer members 12-15 along the adjacent edges of lip 28 and collar 31. Each of corner members 12-15 is further provided at its lower edge with an extension or corner bead 33. As will be apparent, when stacked vertically, a corner bead 33 of one container will engage a corresponding corner groove 32 of .a like container. Each of comer members 12-15 is joined to its respective adjacent sidewalls 2-5 by a pair of accordian-type side hinges, 35, 36, shown in more detail in FIGS. 4-7, and to bottom member 16 by a similar accordian-type bottom hinge 37. A v-shaped clearance slot 38 and a hinge 39 is provided in collar 31 in the vicinity of the upper ends of side hinges 35-36 to provide a pivot point and clearance to facilitate the extension of movable corner members 12-15.
As shown in more detail with reference to corner member 13 in FIG. 2, corner member 15 in FIG. 3, and FIG. 12, each of corner members 12-15 is further provided with a corner groove 40. Cover groove 40 is provided to extend about the upper interior edge of corner bead 33 in the undersurface of a base 44 of each of comer members 12-15. Base 44 extends horizontally from each of corner walls 8 inwardly and is joined with bottom member 16 through hinge 37. As will be apparent, cover groove 40 is adapted to receive a corresponding bead on a cover to be described. hereinafter. Bottom member 16 is provided with a plurality of interlocking rib members 45 for providing mechanical strength. As previously described, bottom member 16 is domed, typically 1 inch in the center, so as. to provide an upwardly directed convex surface for increased mechanical strength and for resisting twisting of container 1 in use. A plurality of brace members 46 are further provided in the under-surface of lip 28 at the opposite endsof corner groove 32 for additional mechanical strength.
With reference to FIGS. 4,5 it will be noted that when corner members 12 -15 are in a fully contracted or nesting configuration, as shown, the vertically rising walls 8 forming comer members 12-15 assume an inwardly directed draft of typically 4 degrees from top to bottom. When corner members 12-15 are in a fully extended r stacking configuration, the vertically rising walls 8 forming corner members 12-'-assume an outwardly directed draft of typically lfrom top to bottom. The draft of corner member 12-15 assumed in the stacking configuration is such that the corner bead 33 in the lower edge of comer members 12-15 assumes a position and is able to mate with a corresponding corner groove 32 in lip 28 at the upper edge of comer members 12-15 of a like container. By so constructing corner members 12-15 such that the lower edges of wall 8 extend outwardly beyond the upper edges of the wall 8 forming corner members 12-15, the forces on corner members 1215 during stacking, as shown in FIG. 8 are directed inwardly resulting in increased stability.
Referring to FIGS. 8-11, container 1 is further provided with a domed cover 50. Cover 50 comprises a pair of downwardly extending flanged arms 51, 52 adapted to mate and lock within cover lock slots 24, 25 in sidewalls 2,4. A plurality of cover beads 53 are provided about the corners of cover 50. As shown in detail in FIG. 12, cover beads 53 are adapted to engage cover grooves 40in the bottom of comer members 12-15 when one container is stacked on top of another. The dome of cover 50 extends inwardly and upwardly from a horizontally extending margin about the edges of dome 50. The margin 54 is made larger in the vicinity of the comers of cover 50 to correspond with the base members 44 in cover members 12-15 for providing a platform on which a like container may rest. The height, size and shape of the dome of cover 50 is identical to the height, size and shape of the dome of bottom member 16 such that when two or more containers together with their respective covers 50 are stacked one on top of the other, the cover 50 of one container will mate with the bottom member 16 of the above container in a male-female relationship. This construction has been found to reduce slipping and twisting of one container relative to another during shipping. Cover member 50 is also provided "with a plurality of air vents 53 located in arms 51, 52.
The containers of the invention can be readily fabricated from any suitable moldable material including the various plastics, metals, etc., employing conventionaltechniques such as blow molding, vacuum molding, and injection molding. High density polyethylenes are especially desirable materials from which to fabricate the containers of the invention.
The containers of the invention can be fabricated in various sizes depending upon how the container is to be employed. The containers are particularly adapted for fabrication in the larger sizes useful in the field in the mechanized harvesting of fruits and vegetables. For such use containers having a depth of about 24 inches, a width of about 42 inches, and a length of about 48 inches have been found particularly useful. In such containers the dimensions of the various elements would be generally in proportion to the above-given dimensions. The invention is not to be limited to containers of any particular dimensions or particular dimensions of particular elements comprising the containers.
While an embodiment of the invention has been described for illustrative purposes, the invention obviously is not limited thereto. Various modifications will be apparent to those skilled in the art in view of this disclosure. Such modifications are within the spirit and scope of the invention.
