Container for bulk material

A container for bulk material, comprising:

• a front wall, a back wall and opposite end walls joined along opposite longitudinal side edges to form a rectangular enclosure having an open upper end and an open lower end;
• a planar bottom closing the lower end of the enclosure;
• a planar lid closing the upper end of the enclosure, said lid comprising a front flap, a back flap and opposite end flaps each integrally joined along a fold line at one edge thereof to an end of a respective one of said enclosure walls and having an opposite free edge, said flaps being folded inwardly about said fold lines over the enclosure to close the open upper end of the enclosure;
• said planar lid and planar bottom, respectively, forming corners with said front, back and opposite end walls;
• a foldable pour spout in said lid which may be opened to pour material from the enclosure and closed to prevent loss of material from the enclosure, said pour spout being defined by a plurality of diagonal fold lines in one of said end flaps forming a first, triangularly shaped center panel and second and third triangularly shaped side panels on opposite sides of the center panel, said triangular side panels being contiguous to a respective one of said front and back flaps, and a diagonal fold line in each of said front and back flaps, defining fourth and fifth triangularly shaped panels in said front and back flaps, respectively, that are contiguous to and form mirror images with said second and third triangular panels, said one end flap being folded inwardly about the fold lines therein over the open upper end of the enclosure so that the second and third triangularly shaped panels overlie the first triangularly shaped panel therein, and the fourth and fifth triangularly shaped panels in the front and back flaps, respectively, overlie the second and third triangularly shaped panels in said one end flap, thereby defining triangularly shaped corners on the front and back flaps which may be grasped and lifted to expose said first triangularly shaped panel that may then be lifted and pulled forward, unfolding said triangularly shaped panels about their respective fold lines to form said pour spout, with said first triangular shaped panel defining the bottom of the pour spout and the second through fifth triangular shaped panels defining the sides of the spout;
• and
• said one end flap having a length between the fold line at said one edge and the opposite free edge that is less than the length of the front and back flaps, and each of said front and back flaps having a first portion contiguous to said one end flap that has a length the same as the length of said one end flap.
