Abstract
A paperboard bulk bin particularly suited for use in handling and transporting of large sections of meat products and the like is of two-piece construction, one portion being a side wall formed of alternating, foldably connected, rectangular upstanding side and corner panels, and a peripheral base support formed of interconnected horizontally disposed stepped flaps and locking flaps. The second portion is a bottom wall formed from a flat panel and having a perimeter corresponding to the bottom edges of the side and corner panels, and overlying the peripheral support base. The alternate stepped flaps and locking flaps are specifically designed in order to form a snap-lock peripheral base portion which holds the paperboard bulk bin in shape and is adapted to receive the bottom wall for subsequent loading and transporting of the meat products.
Claims16
A paperboard bulk bin comprising:
- a side wall formed from a plurality of alternating, foldably connected, substantially rectangular upstanding side and corner panels, each corner panel having a horizontally disposed stepped flap foldably connected to the bottom edge thereof, each stepped flap being of a width corresponding to the width of the associated corner panel at the bottom edge thereof and having a tongue portion of reduced width at the opposite free edge thereof;
- each of said side panels having a horizontally disposed, substantially rectangular locking flap, foldably connected to the bottom edge thereof, each said locking flap having opposed cut-outs on opposite side edges thereof, each said cut-out being intermediate the length of said side edge, said stepped flaps and locking flaps being in interengaged locking relationship to form a peripheral base support for the bulk bin;
- and
- a bottom wall formed from a substantially flat, horizontally disposed panel insert having a perimeter corresponding to the bottom edges of said side and corner panels and overlying the said peripheral support base.
A paperboard bulk bin comprising:
- a side wall formed from a plurality of alternating, foldably connected, substantially rectangular upstanding side and corner panels, each corner panel having a horizontally disposed stepped flap foldably connected to the bottom edge thereof, each stepped flap being of a width corresponding to the width of the associated corner panel at the bottom edge thereof and a tapered tongue portion of reduced width at the opposite free edge thereof;
- each of said side panels having a horizontally disposed, substantially rectangular locking flap, foldably connected to the bottom edge thereof, each said locking flap having opposed arcuate cut-outs at opposite side edges thereof, each said cut-out being intermediate the length of side edge, and with the free edges of said locking flap including tab portions of generally rectangular configuration, said stepped flaps and locking flaps being in interengaged locking relationship such that said rectangular tabs overlie the tapered tongue portion of the contiguous stepped flap to form a peripheral base support for a bulk bin;
- and
- a bottom wall formed from a substantially flat, horizontally disposed panel insert having a perimeter corresponding to the bottom edges of said side and corner panels and overlying said peripheral support base.
A paperboard blank for a bulk bin, which comprises:
- a plurality of alternating, foldably connected, substantially rectangular side panels and corner panels, each corner panel having a stepped flap foldably connected to the bottom edge thereof, each stepped flap being of a width corresponding to the width of the associated corner panel at the bottom edge thereof and having a tongue portion of reduced width at the opposite free edge thereof;
- each said side panel having a substantially rectangular locking flap foldably connected to the bottom edge thereof, each said locking flap having opposed cut-outs at the opposite side edges thereof, each said cut-out being intermediate the length of said side edge;
- and
- said foldably connected side panels, corner panels, stepped flaps and locking flaps being connected along scored, fold lines.
