Abstract

In a bin box formed of corrugated board and shaped having upper, bottom and a pair of side walls, being folded into the tubular form, with a series of flaps provided at the back end to provide closure thereat, and a pivotal panel foldably connected to the bottom wall at the opposite or front end of the box, with said panel having lateral flaps foldably connected to either side, with said flaps being arranged interiorly of the box and adjacent its side walls, with protruding portions provided upon the upper end of each lateral flap so as to limit the extent of the outward pivotal disposition of the pivotal panel. Another flap connects with the upper wall at this front of the box, with said flap normally providing for full closure across this end of the box, but also includes a line of separation so that a portion of said flap can be removed, leaving a marginal flap that functions as a display panel for the box when used for marketing of granular or bulk materials.
