Bulk bag for dense materials

Abstract

A bulk bag for dense materials includes side panels seamed together to form side walls having first and second ends and at least one end wall secured to the first ends of the side walls with the seams connecting the side panels to form the side walls located at points substantially spaced from the adjacent corners of the end wall. Four baffles extend across the corners of the end wall and are secured to the side panels. One or more additional baffles are secured in the side walls seams and extend entirely across the interior of the bulk bag to maintain the bulk bag in a rectangular cross sectional configuration when filled with dense materials.

What is claimed is:  
     
         1 . A bulk bag for dense materials comprising: 
 four side panels each seamed to at least one adjacent side panel to form four side walls having first and second ends and defining an interior area substantially rectangular in shape;    at least one end wall having four corners and seamed to the first ends of the side walls with the seams connecting the side panels to form the side walls located at points substantially spaced from the adjacent corners of the end wall;    four baffles each extending diagonally across one of the corners of the end wall and having opposite ends each seamed to one of the side panels; and    at least one additional baffle extending entirely across the end wall and having opposite ends seamed to opposite side walls of the bulk bag.    
     
     
         2 . The bulk bag for dense materials according to  claim 1  wherein the opposite ends of the additional baffle are secured in the seams forming the opposite side walls.  
     
     
         3 . The bulk bag for dense materials according to  claim 2  further characterized by a pair of additional baffles disposed substantially parallel to one another and each having opposite ends secured to the opposite side walls of the bulk bag.  
     
     
         4 . The bulk bag for dense materials according to  claim 3  wherein the opposite ends of each of the additional baffles is secured in one of the seams defining one of the opposite side walls of the bulk bag.  
     
     
         5 . The bulk bag for dense materials according to  claim 2  further characterized by a pair of additional side walls disposed perpendicularly to one another and each having opposite ends secured to opposite side walls of the bulk bag.  
     
     
         6 . The bulk bag for dense materials according to  claim 5  wherein the opposite ends of each of the additional baffles is secured in a seam defining its respective side wall.  
     
     
         7 . A bulk bag for dense materials comprising; 
 four side panels each seamed to an adjacent side panel to form four side walls having first and second ends and defining an interior substantially rectangular in shape.    
     
     
         8 . At least one end wall having four corners and seamed to the first ends of the side walls with the seams connecting the side panels to form the side walls located at points spaced substantially equi-distant from the adjacent corners of the end wall; 
 four baffles each extending diagonally across one of the corners of the end wall and having opposite ends each seamed to one of the side panels;    an additional baffle having opposite ends secured in side wall seams located on opposite sides of the end wall and extending entirely across the end wall; and    the four baffles and the additional baffle each having apertures formed therein to permit the passage of material therethrough.    
     
     
         9 . A bulk bag for dense materials comprising four side panels each seamed to an adjacent side panel to form four side walls having first and second ends and defining an interior substantially rectangular in shape; 
 at least one end wall having four corners and seamed to the first ends of the side walls with the seams connecting the side panels to form the side walls located at points substantially spaced from the adjacent corners of the end wall;    four baffles each extending diagonally across one of the corners of the end wall and having opposite ends each seamed to one of the side panels;    two additional baffles disposed parallel to one another and each having opposite ends secured in side wall seams located on opposite sides of the end wall; and    the four baffles and the two additional baffles each having apertures formed therein to permit the passage of material therethrough.    
     
     
         10 . The bulk bag for dense materials according to  claim 8  wherein the four side panels each having a diagonally extending baffle secured thereto are arranged in pairs at opposite ends of the end walls with the pairs being separated by two additional side panels thereby defining a relatively long, relatively narrow bulk bag.  
     
     
         11 . A bulk bag for dense materials comprising; 
 four side panels each seamed to at least one adjacent side panel to form four side walls having first and second ends and defining an interior area substantially rectangular in shape;    at least one end wall having four corners and seamed to the first ends of the side walls with the seams connecting the side panels to form the side walls located at points substantially spaced from the adjacent corners of the end walls;    four baffles each extending diagonally across one of the corners of the end wall and having opposite ends each seamed to one of the side panels;    two additional baffles disposed perpendicularly to one another and each having opposite ends secured in one of the side walls seams; and    one of the additional baffles having an aperture formed therein with the other additional baffle extending through the aperture.
