Abstract:
1. An improved bulk bag construction, comprising: a. a plurality of vertical sidewall panels, each panel having first and second vertical edges; b. a plurality of lifting loops, each having a first and second leg portion, wherein the first and second leg portions of each lifting loop have unequal lengths, wherein the first and second leg portions of each lifting loop terminate at a distance from a bottom edge of each of the vertical sidewall panels and wherein the first leg portion of each lifting loop extends from the first vertical edge of each vertical sidewall panel and the second leg portion of each lifting loop extends from the second vertical edge of each sidewall panel; c. each first vertical edge of the vertical sidewall panels stitched to an adjoining second vertical edge of the sidewall panels forming four sidewalls to define a bulk bag enclosure space wherein the first leg portion of one lifting loop and the second leg portion of an adjacent lifting loop are stitched in between the first vertical edge of one sidewall panel and the second vertical edge of an adjacent sidewall panel to form a single line of stitching; d. each of the lifting loops terminating at a center point of each of the four sidewalls, when the panels are stitched together and wherein corners of the bag do not have stitch points; and e. a dart formed in the stitch line of each adjoined sidewall panel, so that an upper portion of the bag forms a bottleneck configuration, while each of the first and second leg portions of the lifting loops are stitched into fabric defining the dart.
