Definitions
- a container of boxlike construction comprising top and bottom caps, an intermediate open ended section between the top and bottom caps and two similar rigid frames interposed between each cap and the intermediate section, wherein each frame is T-shaped in cross section and comprises a flange interposed between adjacent end faces of a cap and the intermediate section to form a butt joint therebetween and upwardly and downwardly projecting walls located externally of the container and retaining the respective edges of the caps and of the intermediate section against outward expansion.
- a container of boxlike construction comprising at least two tubular sections and a plurality of similar rigid supporting frames, each of which frames comprises a flange interposed between adjacent edges of a pair of sections to form a butt joint therebetween and upwardly and downwardly projecting walls located externally of the container to retain the respective edges of the sections against outward expansion.
- the combination of a boxlike container and a supporting pallet comprising a plurality of tubular sections and a plurality of similar rigid supporting frames, each of which frames is T-shaped in cross section and comprises a flange interposed between adjacent edges of a pair of sections to form a butt joint therebetween and upwardly and downwardly projecting walls located externally of the container to retain the respective edges of the sections against outward expansion, the plan outline of the pallet being similar to the plan outline of the container and the container being mounted on the pallet with one of the said frames interposed between the pallet and the container to locate the container on the pallet and resist lateral dislodgernent of the container from the pallet.

- FIG. 3 is a perspective view of a detail of the container of FIG. 1;
- FIG. 4 is a section through a modification of the frame of FIG. 2;
- FIG. 5 is a section through a modification of the frame of FIG. 4;
- FIG. 6 is a perspective view of a part of a further frame
- FIG. 7 is a section through a detail of a modification of the container of FIG. 1'.
- FIG. 8 is a detail of a part of the container of FIG. I mounted on a,pallet.
- FIG. 1 a boxlike container is indicated generally at 10, which comprises an open ended, intermediate section 11, two similar rectangular frames l2 and 13, a liner 14, an end section forming a bottom cap 15 and an end section forming a top cap 16.
- the liner, the two end caps and the intermediate section are formed from a multilayer, corrugated fiberboard, for instance the material sold under the Trade Mark Tri-Wall Pak.
- the end caps and the intermediate section can be formed to the shape-shown in any convenient manner and are preferably formed by slotting and bending a blank to the required shape and then adhering the edges with an adhesive or with staples.
- the liner is preferably formed in the same manner.
- the two frames 12 and 13 are formed from galvanized steel to give structural strength and rigidity to the assembled container.
- a cross section through the frame 12 is shown in FIG. 2, from which it will be seen that the frame is T-shaped in section, comprising an inwardly directed, horizontal flange I7 and upper and lower retaining walls 18 and 19.
- the other frame 13 is similar to the frame 12 and comprises a flange 20 and upper and lower retaining walls 21 and 22.
- the container 10 is assembled by placing the bottom cap IS on the floor with its open end facing upwardly and inserting the liner l4 inside the cap.
- the liner 14 is a snug fit in the cap and serves as a guide for the other parts of the container.
- the frame 12 is next passed over the liner and seated on the upper edge of the cap 15, the dimensions of the frame 12 and cap 15 being such that the cap 15 fits snugly within the lower retaining wall 19 of the frame.
- the intermediate section 11 is then passed over the liner and seated on the flange 17 of the frame 12; the other frame 13 is seated on the upper edge of the section 11 and finally the top cap 16 is seated on the flange 20 of the-frame 13.
- straps 23 are wrapped and tied around the container to secure the assembled parts together for handling as a single unit.
- the wall thickness of the sheet material from which the end caps and the intermediate section are formed is approximately equal to the width of the flanges on the two frames 12 and I3, as shown in FIG. 3, so that there are no projections or recesses in the inner surfaces of the container and the frames form a butt joint between the walls of the end cap and the wall of the section. Furthermore, the outer surfaces of the container are approximately flush, except for the retaining walls of the two frames, which are relatively thin.
- the sidewalls are broken down into three components or sections each of which is equal in height to one-third of the total weight of the container and the horizontal edges of which are constrained by relatively strong frames.
- the resistance of the container 10 to compression is thus much greater. by virtue of its modular structure than a conventional container of the same height but having sidewalls formed from single vertically continuous panels.
- the height of the container 16 can be increased by adding a further intermediate section or sections without substantially reducing the resistance of the container to compression.
- the section 11 can be omitted and the container formed from the top and bottom caps and the frame 12.
- FIGS. 4 and 5 a frame 24 is shown in cross section, which is similar to the frame 12 except that it has a flange 25 formed along its inner periphery with a vertical upper lip 26 and a vertical lower lip 27.
- the vertical lips 26 and 27 provide a support for the sidewall of the section fitted into he frame 24 and act as a restraint against inward collapse which increases the compressive strength of the container.
- a frame 28 is shown in section which is similar to the frame 24 except that it has only an upper vertical lip 29.
- the frames are preferably formed from galvanized steel but can, alternatively be formed from any other material having the desired properties, for instance certain synthetic resins. They can be formed from four separate sections which are welded, riveted or bolted at the corners, or from a single section which is bent, on a sharp radius at three comers and welded or otherwise joined a the fourth corner.
- the flange which projects inwardly on each frame is normally continuous but in certain applications, particularly where the flange is fonned with a lip it may be advantageous to provide a frame with an interrupted flange.
- a frame 30 having an interrupted flange 3 l is shown in FIG. 6.
- the frames are rectangular in shape, but nonrectangular polygonally shaped containers are envisaged in which the frames would also be polygonal.
- the container can be cylindrical and the frames would then be circular.
- an end section or cap 32 can have inclined sidewalls 33, Le. the section is shaped as a truncated pyramid, in which event a supporting wall 33 of frame 35 on which the section rests is inclined inwardly at an acute angle to flange 36 of the frame to correspond with the slope of the sidewalls of the section.
- the end sections, the intermediate sections and the liner of the container 10 are preferably formed from multilayer corrugated fiberboard as this material has many advantageous characteristics. However, these units can, if required be formed from any other suitable material which meets struc tural and cost requirements, for instance other forms of fiberboard and multilayer sheet material can be used.
- a further advantage of the container 10 is that it lends itself readily to mounting on a conventional type of pallet 37, as shown in FIG. 7.
- the pallet 37 comprises transverse slats 38 and a rectangular hardboard platform 39, the plan outline of which is the same as the plan outline of the container 10.
- a frame 40 similar to the frames 12 and 13 is placed on the pallet with the pallet a snug fit inside the lower vertical wallof the frame 40.
- the bottom cap of the container E0 is then placed on the flange of the frame 40, a close fit within the upper vertical wall of the frame and the container is then assembled in the manner described above.
- the straps 23 are preferably used and passed beneath the pallet.
- the container can alternatively be secured to the pallet by any conventional means, for instance by nailing, stapling or glue ing.
- a container can be constructed 01 open ended sections only, for instance the container can be mounted on a pallet prior to loading and the pallet then forms the floor or base of the container. The closed sections or caps then become redundant.
- a container of boxlike construction comprising top and bottom caps, an intermediate open ended section between the top and bottom caps and two similar rigid annular frames intcrposed between each cap and the intermediate section, wherein each frame is T-shaped in cross section and comprises a flange interposed between adjacent end faces of a cap and the intermediate section to form a butt joint therebetwcen and upwardly and downwardly projecting walls located externally of the container and retaining the respective edges of the caps and of the intermediate section against outward expansion.
- the inner edge portion of the flange being substantially adjacent the interior surface of the cap and intermediate section adjacent thereto.
- each rigid frame includes an upwardly extending lip and a downwardly extending lip on the radially inner edge of the flange, the lips being located on the inside of the container to retain the edges of the adjacent caps and section against inward collapse.
- a container of boxlike construction comprising at least two tubular sections and a plurality of similar rigid supporting frames, each one of which frames comprises a flange interposed between adjacent edges of a pair of sections to form a butt joint therebctween and upwardly and downwardly projecting walls located externally of the container to retain the respective edges of the sections against outward expansion.
- each rigid frame includes an upwardly extending lip and a downwardl extending lip, the lips being located on the radially inner edgt of the said flange to retain the edges of the adjacent sections against inward collapse.
- a boxlike container and a supporting pallet comprising a plurality of tubular sections and a plurality of similar rigid supporting frames, each one 01 which frames is T-shaped in cross section and comprises a flange interposed between adjacent edges of a pair of sections to form a butt joint therebetween and upwardly and downwardly projecting walls located externally of the container to retain the respective edges of the sections against outward expansion, the plan outline of the pallet being similar to the plan outline of the container and the container being mounted on the pallet with one of the said frames interposet. between the pallet and the container to locate the container on the pallet and resist lateral dislodgement of the container from the pallet.
- a container of boxlike construction comprising a car portion, and an intermediate open ended section atop the car and a rigid annular frame interposed between the cap and lhl open ended section, wherein the frame is T-shaped in cros: section and comprises a flange interposed between adjacen end faces of the cap and the open ended section to form a but joint therebetween and upwardly and downwardly projectin walls located externally of the container and retaining tht respective edges of the cap and of the open ended section ends of the sections when disposed adjacent to one another to form a butt joint therebetween and upwardly and downwardly projecting walls located externally of the container and retaining the respective edges of the said pair of sections against outward expansion, the inner edge portion of the flange being substantially adjacent the interior surface of the sections.
