Estimating the term…
A container is disclosed having a plurality of interconnected panels forming sidewalls surrounding a central space. Flaps extend from lower sidewall edges and fold along fold lines to form a bottom. Support flanges are arranged along upper sidewall edges on oppositely facing sidewalls. The support flanges are oriented at right angles to the sidewalls and provide a support surface allowing the containers to be stacked one atop another without collapsing or nesting within each other. Each support flange is supported by a truss formed by a panel segment extending angularly from the support flange to a support panel biased against the sidewall to which the support flange is attached by a retaining flap extending from an inner sidewall layer. Locking tabs at the ends of each panel segment are received within recesses positioned in sidewall panels perpendicular to the support flanges. The container is transformed from a knockdown formed from a unitary blank.
A container upon which another container may be stacked, said container comprising:
A container according to claim 16, formed from a unitary piece of said paperboard, wherein said support flange, said support panel and said panel segment is defined by fold lines formed in said paperboard.
A container according to claim 15 and formable from a knockdown having first and second knockdown walls attached to one another at first and second knockdown corners to form a substantially flat assembly, said first knockdown wall including said first sidewall, another of said sidewalls, said first support flange, said first panel segment, said first support panel and said first retaining flap in a substantially same first plane, said second knockdown wall including said second sidewall, another of said sidewalls, said second support flange, said second panel segment, said second support panel and said second retaining flap in a second substantially same plane parallel to said first plane.
Support surfaces useable on containers to permit stacking of said containers one atop another without nesting, said containers comprising a plurality of interconnected panels forming sidewalls surrounding a central space, said sidewalls having flaps extending therefrom and foldable to form a bottom, a first and a second of said sidewalls facing one another in opposing relationship, said support surfaces comprising:
Support surfaces according to claim 22, wherein said support flanges, said support panels, said panel segments, said sidewalls and said flaps comprise corrugated paperboard.
Support surfaces according to claim 23, wherein said first and second support flanges, said first and second panel segment and said first and second support panels are integrally formed with said first and second sidewalls respectively.
Support surfaces according to claim 23 wherein said containers are formed from a knockdown having first and second knockdown walls attached to one another at first and second knockdown corners to form a substantially flat assembly, said first knockdown wall including said first sidewall, said first support flange, said first support panel, said first panel segment, and one of said adjacent sidewalls attached to said first sidewall, all located in a substantially same first plane, said second knockdown wall including said second sidewall, said second support flange, said second support panel, said second panel segment, and another of said sidewalls attached to said second sidewall, all located in a substantially same second plane parallel to said first plane.
A container comprising:
