Abstract
A bag for transporting bulk quantities of powdered or granular material, the bag having a top and four separate lifting loops disposed around the top, each loop having a bight and two spaced legs. Each leg is secured to the fabric of the bag by folding a section of the fabric to a substantially S-shaped configuration along fold lines extending from the top towards the bottom of the bag to form three overlying thicknesses of fabric and stitching through the three thicknesses of fabric and the leg. The resulting characteristic shape of the bag provides inherent stability to the bag and the stitching technique allows high factors of safety to be obtained. In a presently preferred embodiment, the filled bag has a shape resembling that of a wide-necked bottle, with a broader base and a tapered top.

A bag for transporting bulk material, the bag having a top and having four separate lifting loops disposed around the top, each loop having a bight and two spaced legs, and each leg being secured to the fabric of the bag by being disposed along a section of the fabric folded to a substantially S-shaped configuration along fold lines extending from the top towards the bottom of the bag to form three overlying thicknesses of fabric and stitching through the three thicknesses of fabric and the leg.
A bag for transporting bulk material, the bag having an open top and having four separate lifting loops disposed around the open top, each loop having a bight and two spaced legs, and each leg being secured to the fabric of the bag by folding the fabric around the leg and then back over itself along fold lines extending from the top towards the bottom of the bag and stitching through the three widths of fabric and the leg.
