Patent ID: 8678652

Claim:
A flexible container bag assembly comprising: an exterior body of flexible material including a plurality of sidewalls attached to each other at the edges of adjacent sidewalls, the sidewalls defining corners at the position of attachment of the sidewall edges thereby defining bag corners, and a bottom panel having plural bottom panel boundary edges, the bottom panel boundary edges being attached to sidewall edges not attached to each other, thereby providing an enclosed interior volume configuration capable of retaining loose or granular material and including lifting loops at or immediately adjacent at least two of the bag corners; a plurality of baffles comprising a web fabric, one baffle spanning each of the bag corners defined by the sidewall edges, the baffle having an essentially rectilinear shape, one longitudinal edge of each baffle being attached to a sidewall and the other longitudinal baffle edge being attached to an adjacent sidewall thereby defining a corner volume, the two longitudinal baffle edges defining between them a width w of a baffle, each baffle having at least two apertures in the web fabric of the baffle, the width of each aperture being less than the width w of the baffle, the apertures in the web fabric permitting access between the interior volume and the corner volumes, the baffles thereby assisting to maintain the rectangular configuration of the container; and at least one flap at least partially covering each of the at least two apertures, each flap comprising a flap base attached to the web fabric and a flap bend or point opposite the flap base that is not directly attached to the web fabric.
