Benefits of technology
This patent describes a new design for a bulk bag that can be easily lifted by using lift hoops. The bulk bag body has a top portion, a bottom portion, and a side portion, and there are multiple straps with eyelets attached to the body. Each strape has a corresponding lift hoop that is securely connected to the eyelet of the strape. This allows the bag to be lifted by the lift hoops. The straps may be monofilament or multifilament. The technical effect of this design is that it makes it easier and safer to lift and handle the bulk bag.
Problems solved by technology
A disadvantage of multifilament straps lies in their incompatibility in elasticity with the polypropylene body fabric of the bulk bag.
When the bulk bag is lifted by its multifilament straps, the highly elastic multifilament straps stretch out more than the polypropylene body fabric, which may result in the breakage of the sewing stitches and / or the body fabric at the strap attachment areas.
Another disadvantage is that multifilament straps are also more expensive than monofilament straps.
A disadvantage of monofilament straps is that the monofilament strap is more stiff and harder to use when being placed onto the filling station hooks.
The monofilament straps also stand up when not in use, which is not desirable in many situations since the upright straps can cause interference with the machinery around the bulk bags.

A bulk bag and method of making the bulk bag uses lift hoops that are securely linked to eyelets of lift straps that are attached to a bulk bag body so that the bulk bag can be lifted by the lift hoops. The bulk bag body includes a top portion, a bottom portion and a side portion. The lift straps may be attached to the bulk bag body such that at least portions of the lift straps extend along the side portion of the bulk bag body at an angle from the top portion of the bulk bag body to the bottom portion of the bulk bag body.
Description
CROSS REFERENCE TO RELATED APPLICATION[0001]This application is entitled to the benefit of U.S. Provisional Patent Application Ser. No. 61 / 759,335, filed on Jan. 31, 2013, which is incorporated herein by reference.BACKGROUND OF THE INVENTION[0002]Bulk bags are used for the transportation of bulk materials. Bulk bags are usually fabricated by stitching or sewing polypropylene woven fabric. Lift straps are typically sewn onto the body fabric so that the bulk bag can be lifted by a forklift or other equipment.[0003]Lift straps of a bulk bag are commonly made of either multifilament or monofilament materials. Multifilament straps are generally softer and easier to handle by workers to place the straps onto hooks of a filling station equipment. The multifilament straps drop down naturally by gravity when not in use. Therefore, the multifilament straps do not interference with other machinery when the bulk bag is moved or transported.[0004]A disadvantage of multifilament straps lies in th...
