Abstract

A longitudinally bisected storage drum includes a pair of hemi-cylindrical drum segments each being formed by a pair of semicircular end panels which are joined to, and spaced-apart by, a side wall having a hemi-cylindrical wall section and a substantially rectangular planar wall section. The planar wall section of one drum segment defines a longitudinally oriented re-entrant groove which unites with a longitudinally oriented tongue protruding from the planar wall section of the other drum segment. Therefore, when the tongue and groove are united with one another, an overall cylindrical drum structure will result. The closely adjacent planar wall sections of each drum segment establish a diametrical parting plane when the tongue and groove are united with one another while the hemicylindrical wall segments are provided with longitudinally spaced-apart and outwardly protruding pairs of roll stops close to this parting plane. Thus, by simply reversing the vertical orientation of bungholes formed in each of the upper end panels (e.g., by rolling the drum along its cylindrical side wall until the it rests upon the other set of roll stops), the contents within the hemi-cylindrical drum segments can selectively be dispensed by positioning that segment'"'"'s bunghole in the lower vertical position relative to the other bunghole.

Claims

1. A multi-compartment storage drum comprising:

a pair of separably united hemi-cylindrical drum segments;

each said drum segment including upper and lower semicircular end panels which are joined to, and spaced apart by, a side wall having a hemi-cylindrical exterior side wall section and a planar interior side wall section, wherein

said end panels and said interior and exterior side wall sections of each said drum segment collectively establish a compartment to hold a volume of pourable material, and wherein

said interior side wall sections of said drum segments are disposed closely adjacent to one another when said drum segments are united so that said drum has a generally cylindrical shape by virtue of said exterior hemi-cylindrical exterior side wall sections,

said closely adjacent interior side wall sections establishing a longitudinally diametrical parting plane of said storage drum, and wherein said storage drum further comprises,

circumferentially paired roll stops outwardly extending from said exterior side wall sections of said drum sections and asymmetrically straddling said longitudinally diametrical parting plane; and

bung holes formed in each of said end panels and disposed closely adjacent said parting plane such that said bung holes are oriented substantially vertically with respect to one another when said drum is resting on one set of said paired roll stops and such that said vertical orientation of said bung holes may be reversed by rolling said storage drum along said side wall sections until said drum rests upon another set of paired roll stops.

2. A storage drum as in claim 1, further comprising a groove formed in the planar interior side wall section of one drum segment, and a tongue outwardly protruding from the planar interior side wall section of the other drum segment, said tongue and groove being conformably shaped so as to be interlockable and thereby separably unite said drum segments one the other.

3. A storage drum as in claim 2, wherein said tongue and groove are oriented longitudinally.

4. A storage drum as in claim 3, wherein at least one terminal end of said tongue and groove terminates short of an adjacent end panel.

5. A storage drum as in claim 3, wherein said tongue includes an arcuate head portion and a neck portion of reduced cross-sectional dimension joining said head portion to said planar interior side wall section of the other drum segment.

6. A storage drum as in claim 5, wherein said groove includes an arcuate receiving channel conforming to said head portion of said tongue and an entranceway corresponding substantially to said reduced cross-sectional dimension of said neck portion.

7. A storage drum as in claim 6, comprising upper and lower sets of said circumferentially paired roll stops.

8. A storage drum as in claim 7, wherein each of said roll stops defines a convex arcuate surface.

9. A storage drum as in claim 1, wherein said exterior side wall sections include handles.

10. A storage drum as in claim 9, wherein said handles are recessed.

11. A storage drum as in any one of claims 1, 2, 3 or 4, wherein said exterior side wall sections include circumferential band-receiving channels, and restraining bands disposed in said band-receiving channels to prevent relative separation of said drum segments.

12. A drum as in claim 1, wherein lower end panels include arcuate reinforcing structures.

13. A drum as in claim 12, wherein said reinforcing structures are recessed relative to said lower end panels.

14. A drum as in claim 1, further comprising caps covering said bung holes.
