PATENTEnJuLzsxsM SHEU lt UF 8 mj www alsa-sn 14 PMENIEB JUL 2 31914 i j l NIEST AND STACK CONTAINER structed that an upper container will nest within a like oriented lower container, or an upper container will stack on a lower container when said upper container is turned with respect to said lower container, are well known in the art. Such prior art containers of which we are aware are usually provided with stacking means so constructed, and/or so located, as to require rather precise registering or engagement between the stacking feet on the upper container and the corresponding stacking saddles on the lower container.
Said precise registering or engagement has, at least in many instances, created problems in stacking and has lessened the utility `of such containers. For example, said required precise registering of the stacking means slows the stacking operation. Another difficulty which is encountered with the prior art containers is that said required precise registering of j the `stacking means makes it necessary for the operator stacking the containers to visually observe the stacking means during the stacking operation. This limits the height to which an operator can ordinarilyfstack the containers without making special Lprovisions.` For example, when the height of a stack of stacked containers approaches or is greater than eye level,'the operator must start a new stack or else employ a ladder.

As here illustrated, said third stacking means can comprise a first stacking lug 52 located at one end of said third border flange 40. Preferably, said stacking lug 52 is secured to stacking lug 16 which projects outwardly from first border flange l2. lt is convenient for said stacking lugs 16 and 52 to be integrally formed, as illustrated. A second stacking lug 54 can be located at the other end of said third border flange 40, and preferably secured to stacking lug 16' which projects outwardly from second border flange 18. It is convenient for said stacking lugs 16 and 54 to be molded integrally, as illustrated. A third bars 44, 46, 48, and 50 are secured to the inner surface of said third rail.
Said last-described embodiment of the invention provides a three-walled container wherein one side of the container is open. Said open side is convenient for reaching into a loaded container in a stack of containers to remove articles therefrom without having to remove the loaded container from the stack of containers. A more preferred embodiment of said three-walled container is described hereinafter.
ln the present most preferred embodiment of the invention, there is provided a fourth wall which is disposed opposite said third wall and which is positioned between and generally perpendicular to said first and second walls. Said fourth wall preferably comprises a fourth border flange 58 which extends along a fourth side of the bottom of the container with the ends thereof being connected to adjacent ends of said first and second border flanges 12 and 18. A fourth upper rim 60 is disposed generally vertically above and has a length slightly greaterthan-the length of said fourth side of said bottom. The ends of said fourth upper rim 60 are connected to adjacent ends of said first and second upper rims 32 and 34. A plurality of inclined bars 62, 64, 66, and 68 extend upwardly between said fourth border flange 58 and said fourth upper -rm 60. When said fourth border flange58 is provided, the lower ends of said inclined bars are secured tothe'outer surface thereof. Preferably, the inclined bars in said fourth wall are inclined oppositely from the inclined bars in said and said second guide recesses 82 and v82' are adapted to receive said second foot 78 while a like container is being moved into stacked relationship above another like container, as described further hereinafter.
The above-described embodiment of the invention wherein the container is provided with three walls has valuable utility in many instances. In a presently more preferred embodiment of said three-walled container, there is provided a partial fourth wall which is disposed opposite the third wall of the container. Said partial fourth wall can comprise a lower border flange 58 like in the above-described four-walled container. A segment of an upper rim 84 can be connected at one end thereof to the end of said first upper rim 32 which is not connected to said third upper rim 42. An inclined bar 86 extends between said fourth border flange 58 and said upper rim segment 84. Another segment of an third wall, as illustrated. A fourth stacking means can project outwardly from said fourth border flange 58, As here illustrated, said fourth stacking means can cornprise a first stacking lug 70 located adjacent but spaced apart from one end of said fourth border flange, and a second stacking lug 72 located adjacent but spaced apartfrom the other end of said fourth border flange 58. A fourth saddle rail 74 provided with nesting clearway means therein to accommodate said fourth stacking means can be secured to the inner surface of said fourth upper rim 60. When said fourth saddle rail is provided, the upper ends of inclined bars 62, 64, 66, and 68 are secured to the inner surface of said support rail 74.
Preferably, said first border flange l2 extends below the plane of the bottom of the container to provide a first foot 76 at one end of the container. Similarly, said second border flange 18 preferably extends below the plane of the bottom of the container to provide a second foot 78 at the other end of the container. Said third and fourth upper rims 42 and 60 are each provided with a first guide recess 80 and 80', respectively, located4 in the upper edge thereof vertically above said foot 76 on first border flange 12. Each of said upper rims 42 and 60 is also provided with a second guide recess 82 and 82', respectively, located in the upper edges thereof vertically above said foot 78 on the bottom of second border flange 18. Said first guide recesses 80 and 80 are adapted to receive said first foot 76,
upper rim 88 can be connected at one end thereof to the end of said second upper rim 34 which is not connected to said third upper rim 42. Another inclined bar 90extends between said fourth border flange 58 and said upper rim segment 88. Preferably, each of said upper rim segments 84 and 88 has a segment of a saddle rail secured to the inner surface thereof. When said saddle rail segments are provided, the upper ends of said inclined bars 86 and 90 are secured to the inner surfaces of said saddle rail segments. Preferably, a pair of spaced apart stacking lugs 92 and 94 project outwardly from fourth border flange 58.
In all the containers of the invention, it is preferred that the bottom border flanges 12, 18, 40, and 58 extend above the plane of the container bottom a small finite distance. The stacking lugs 14, 16, 14', and 16', and the guide and support rails 20 and30, provided on the opposite first and second walls, respectively, comprise the primary stacking means and are provided in all the containers of the invention. The stacking lugs which can project fromthird and fourth border flanges 40 and 58, and the third support rail 58 and fourth support rail 74, comprise supplementary stacking supports in the threeand four-walled containers. Said supplementary stacking supports can be omitted, if desired, in light duty` containers. Said supplementary stacking supports are preferred in heavy duty containers, particularly when loaded containers are to be stacked to considerable heights.
The nesting of the containers of the invention is illustrated in FIG. l5. As there shown, in nesting the corresponding wall of a like oriented'upper container fits directly downward into the corresponding wall of a lower container. For example, the truncated V form of inclined bars'22 and 24 of an upper container fit into the like truncated V form of the inclined bars 22 and 24 of the lower container with the bars of said V forms paralleling each other. A similar fit is obtained with the inverted truncated V forms of inclined bars 26 and 28. The stacking lugs 14 and 16 are accommodated by and passed through nesting clearways B and A, respectively. See FIG. 2. During nesting, the feet 76 and 78 on the bottom of border flanges 12 and 18 of an upper container abut and rest on top of border flanges 12 and 18 of a lower container.
The stacking of the containers of the invention is ili lustrated in FIG. 16. The stacking operation is initiated by turning an upper container with respect to a like lower container. lf the lower container is at a low level, e. g., on the floor or on a low table, the upper container can be placed directly onto the lower container. In stacked position, the grooves 38 in the primary stacking lugs 14 and 16, and 14' and 16', register with crowns 36 on guide and support rails 20 and 30 of the first and second walls, respectively. The upper container is thus supported over the entire length of said rails and 30. When supplemental stacking supports are provided on the side walls of heavy duty containers, e.g., the third and fourth walls, the stacking lugs projecting from said third and fourth walls rest on support rails 74 and 58, respectively. ln all instances, the bottom periphery of the upper container is positioned well below the periphery of the top edge of the upper rims 32, 42, 34, and 60 of the lower container, thus locking the upper container with respect to lateral movement in any direction.
As mentioned above, an outstanding feature of the containers of the invention is the blind stacking which the construction of the containers of the invention makes possible. This feature of the invention is of great value when the containers are being stacked at any height at which it is inconvenient to lift the upper container to a position directly above the lower container. In such instances, the stacking operation can be initiated by placing the feet 76 and 78 on the bottom of border flanges l2 and 18 of the upper container in register with one of guide recesses 80 and 80', and one of guide recesses 82 and 82', of one of the upper rims 42 and 60 of the lower container. The upper container is then moved across the lower container, preferably at a slight tilt so as to bring grooves 38 in the stacking lugs 14 and 14', or 16 and 16', in register with crowns 36 of the guide and support rails 20 and 30, until the bottom periphery of the upper container is within the top periphery of the lower container. Said grooves 38 and crowns 36 thus cooperate with said guide recesses 80 and 82 (or 80 and 82') and feet 76 and 78, in guiding the upper container into proper stacked position. The above-described blind stacking can be readily carried out without visual observation of the guide means by an operator because feet 76 and 78 will readily drop into guide recesses 80 and 82 (or 80 and 82') when an upper container is placed on an upper rim 42 or 60 of a lower container. If necessary, said guide recesses can be readily located with said feet by a slight back and forth lateral movement of the upper container.
The containers of the invention can be fabricated in any suitable manner known to the art. Injection molding, for example, is one presently preferred method for fabricating said containers. Said containers can be fabricated from any suitable material. High density polyethylenes are especially desirable materials from which to fabricate said containers. The high density polyethylenes and other polyolefins prepared by the methods disclosed and claimed by J. P. Hogan et al in U.S. Pat. No. 2,825,721, issued Mar. 4, 1958, are one group of presently preferred materials. Said containers can also be fabricated from butadiene-styrene copolymers, and other plastic materials. lf desired, a reinforcing fibrous material, such as asbestos or glass fibers, can be incorporated in the plastic material. While the various plastics are presently preferred for the manufacture of the containers, it is within the scope of the invention to fabricate said containers from other materials, e.g., lightl weight metals such as aluminum, reinforced pulp materials, etc.
As an example, one model of a container fabricated in accordance with the invention had an overall length of 23"/8 inches, an overall width of 20% inches, and an overall height of 5% inches. Stacking lug 14 had a length of approximately 1% inches. Stacking lug 16 had a length of approximately 2% inches. The inclined bars in the wall of the container were approximately 4 inches in length. The upper surface of the T bars in the gridwork bottom was approximately one-fourth inch wide. The dimensions of the other elements of the container were generall proportional in size.
Herein and in the claims, the word rectangular has been employed generically to include four-sided structures which are generally square and four-sided structures wherein one pair of sides is longer than the other pair of sides.
While certain embodiments of the invention have been described for illustrative purposes, the invention is not limited thereto. Various other modifications or embodiments of the invention will be apparent to those skilled in the art in view of this disclosure.
