1. 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 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, the inner edge portion of the flange being substantially adjacent the interior surface of the cap and intermediate section adjacent thereto.

4. 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 therebetween and upwardly and downwardly projecting walls located externally of the container to retain the respective edges of the sections against outward expansion.

8. The combination of a boxlike container and a supporting pallet, the container comprising a plurality of tubular sections and a plurality of similaR rigid supporting frames, each one 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 dislodgement of the container from the pallet.

9. A container of boxlike construction comprising a cap portion, and an intermediate open ended section atop the cap and a rigid annular frame interposed between the cap and the open ended section, wherein the frame is T-shaped in cross section and comprises a flange interposed between adjacent end faces of the cap and the open ended 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 cap and of the open ended section against outward expansion, the inner edge portion of the flange being substantially adjacent the interior surface of the cap and open ended section adjacent thereto.

10. A container construction comprising a pair of sections each having an open end and a rigid annular frame interposed between the sections, wherein the frame is T-shaped in cross section and comprises a flange interposed between the open 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.
