Abstract
Abstract A drum-like container of fiberboard or similar material supplied in flat knocked-down form and adapted to be set up as a multi-sided receptacle of polygonal transverse cross-section. It is provided with a funnel-like dispensing bottom which is also supplied in knocked-down form and consists of two sections, namely, a peripheral support wall section and a material-directing section. The set-up support wall section within the receptacle will be of similar multi-sided arrangement to fit therein. The set-up material-directing section will be of funnel-like form and when resting on the support section within the receptacle will direct the receptacle.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
237 words
A container assembly comprising a tubular body of fiberboard with a bottom structure at its lower end, said body being formed of side-wall forming panels extending upwardly at the periphery thereof and which said side-wall forming panels are hinged together at vertical hinge lines to form said body of selected polygonal horizontal cross-sectional form, said bottom structure including support means secured to said side-wall panels; said bottom structure also including a funnel-like assembly composed of two main parts consisting of a peripheral support section and a funnel-like material-directing section supported thereby, said support section being of tubular form complemental to that of said tubular body so as to fit therewithin and comprising a plurality of upright support panels hinged together at vertical hinge lines and said upright support panels are equal in number to the said side-wall panels and are disposed in flat contact with the respective said side-wall panels and having lower edges resting on said bottom support means, said funnel-like section comprising a plurality of substantially triangular panels equal in number to said side-wall panels and hinged together at radially-extending hinge lines having wide ends disposed outwardly at the respective body panels and resting on the respective upright support panels and being inclined downwardly to narrower inner ends at a downwardly-opening dispensing outlet, said two main parts being unattached to each other prior to when the triangular panels rest on the respective upright support panels.
Claim 2
Dependent Claim
237 words
A container assembly comprising a tubular body of fiberboard with a bottom structure at its lower end, said body being formed of side-wall forming panels extending upwardly at the periphery thereof and which said side-wall forming panels are hinged together at vertical hinge lines to form said body of selected polygonal horizontal cross-sectional form, said bottom structure including support means secured to said side-wall panels; said bottom structure also including a funnel-like assembly composed of two main parts consisting of a peripheral support section and a funnel-like material-directing section supported thereby, said support section being of tubular form complemental to that of said tubular body so as to fit therewithin and comprising a plurality of upright support panels hinged together at vertical hinge lines and said upright support panels are equal in number to the said side-wall panels and are disposed in flat contact with the respective said side-wall panels and having lower edges resting on said bottom support means, said funnel-like section comprising a plurality of substantially triangular panels equal in number to said side-wall panels and hinged together at radially-extending hinge lines having wide ends disposed outwardly at the respective body panels and resting on the respective upright support panels and being inclined downwardly to narrower inner ends at a downwardly-opening dispensing outlet, said two main parts being unattached to each other prior to when the triangular panels rest on the respective upright support panels.
Claim 3
Dependent Claim
36 words
A container assembly according to claim 1 in which said upright support panels have hinged support flanges at their upper ends upon which rest the wide ends of the respective triangular panels of the funnel-like section.
Claim 4
Dependent Claim
79 words
A container assembly according to claim 1 or 2 in which the bottom structure support means includes a tray-like closure of fiberboard having a flat bottom with a polygonal periphery having upstanding flanges hinged thereto which correspond in number and arrangement to said side-wall forming panels and extend upwardly along corresponding side-wall panels to which they are secured, said flat bottom having a displaceable portion to form a dispensing opening corresponding to the dispensing outlet of said funnel-like section.
Claim 5
Dependent Claim
37 words
A container assembly according to claim 3 in which a pallet is provided on which said flat bottom rests, said pallet having a support part normally supporting said displaceable portion but movable away from that supporting relationship.
Claim 6
Dependent Claim
26 words
A container assembly according to claim 3 in which the closure, tray-like container bottom, support section and funnel-like section each is supplied in flat knocked-down condition.
Claim 7
Dependent Claim
119 words
A container assembly according to claim 1 or 2 in which the support section is formed of the upright support panels hinged together adjacent side hinges and folded at opposed side hinges to provide a folded knocked-down blank in two superimposed layers of upright support panels, each layer consisting of one-half the side-wall forming panels of said body; and the funnel-like section is formed of the triangular panels which are greater in number than the side-wall forming panels of said body but with some of the triangular panels overlapped to provide the same number of triangular panels as the number of said side-wall forming panels, said funnel-like section being folded flat at opposed side hinges into knocked-down fan-like form.
Claim 8
Dependent Claim
42 words
A container assembly according to claim 6 in which each of the triangular panels has said outer wide end adapted to contact an inner surface of a side-wall forming panel and said narrow inner end to cooperate in forming said dispensing outlet.
