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.
Claims7
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.
