"Improved Design For Stabilizing Fabric Bulk Bags"

An improved bulk bag of the type having sidewalls, whereby one or more darts on the upper portion of the bag sidewalls define an area a reduced diameter than the lower portion of the bag sidewalls, so that when product is placed into the bag to a point above the lower portion of the bag sidewalls, the sidewalls are maintained in tension, which provides for a more stable bag which is capable of supporting itself and other filled bags positioned thereupon.

An improved bulk bag of the type having sidewalls, which provides for a more stable bag which is capable of supporting itself and other filled bags positioned thereupon, which comprises an upper portion of the bag sidewalls having a dart formed therein so as to define a reduced circumference of the filled bag at the darts, so that when product is placed into the bag to a point above the darts, the sidewalls are maintained in tension.

An improved fabric bulk bag, comprising:

• a. sidewalls, a top portion and a bottom portion, all defining a bulk space therewithin;
• b. a lower portion of the sidewalls being substantially vertical;
• c. an upper portion of the sidewalls having a dart in place, which defines that portion of the sidewall formed inwardly from the vertical portion of the sidewalls, so that when product is poured into the bag at least to a level above the lowest point of the dart, the lower portion of the sidewalls remain vertical and rigid when placed on a surface or when other filled bags are stacked thereupon.

An improved bulk bag with an upper portion of the sidewalls that is sloped inward from vertical defining a reduced area of the bag sidewalls, so that when the sidewall fabric is stretched upward in the lifting process, creating tension in the vertical fabric, tension will be maintained as the fabric in the reduced area cannot slide back down around the product due to the reduced area of the fabric compared to the product surface area.

An improved bulk bag with an upper portion of the sidewalls that is sloped inward from the vertical so that when the fabric is stretched upward in the lifting process, thereby creating tension in the vertical fabrics, that at least a portion of the tension will be maintained as the fabric cannot slide back down around the product due to the restricted size of the fabric.

An improved fabric bulk bag design which allows more stable stacking of multiple bags filled with product, the bag comprising:

• a. sidewalls, a top portion and a bottom portion, all defining a bulk space therewithin;
• b. at least an upper portion of the sidewalls formed inwardly from the vertical by the use of one or more darts along the sidewalls, so as to define an angled truncated top portion of the bag;
• c. wherein as pressure is applied from above by a second bag stacked on top of a first bag, the pressure meets the floor and then turns 90 degrees toward the side walls of the bag, defining a redirection of pressure through out the entire bag, including the angled portion of the bag.
