ATLANTA , April 10, 2014 () – According to news reporting originating from Washington, D.C., by VerticalNews journalists, a patent application by the inventors Brown, Bobby Glen (Denison, TX); Zulaica, Krystavel (McKinney, TX), filed on September 23, 2013, was made available online on April 3, 2014.

No assignee for this patent application has been made.

Reporters obtained the following quote from the background information supplied by the inventors: "Bulk bags, also known as flexible intermediate bulk containers (FIBCs), may be used to facilitate the receiving, storing, transporting, and discharging of flowable solids and other materials. In addition, forklift trucks and pallets (or skids) have been used to aid in lifting, transporting, positioning, and stacking bulk bags and their contents. Pallets are generally flat structures used to support materials in a stable fashion that are being lifted, transported, positioned, or stacked by a forklift or other similar device or while in shipping containers. Pallets are often bulky, not easily accessible for use, and may add additional costs."

In addition to obtaining background information on this patent application, VerticalNews editors also obtained the inventors' summary information for this patent application: "The present invention provides a bulk bag that may be used to facilitate the receiving, receiving, storing, transporting, and discharging of flowable solids and other materials, including but not limited to, minerals, chemicals, foodstuffs, etc. In some circumstances, the bulk bag can be adapted for use with fluidized materials, semi-liquids and liquids.

"More specifically, the present invention provides a bulk bag that includes a body having sidewalls, a bottom wall and a pair of opposed lift sleeves adapted to receive lifting members for lifting the bag and contents thereof. Each lift sleeve has a first sleeve end and a second sleeve end attached together and proximate to a bottom of the sidewall to form a loop, and a portion of the sleeve extending from the second sleeve end is attached to an adjacent portion of the sidewall such that the loop maintains a substantially open position.

"In addition, the present invention provides a bulk bag that includes a body having sidewalls, a top wall, a bottom wall and a pair of opposed lift sleeves adapted to receive lifting members for lifting the bag and contents thereof. Four handles are attached to a top of the body. Each handle is located proximate to a corner of the body. A spout is attached to the sidewalls, the top wall or the bottom wall to selectively access contents within the body or load contents into the body. Each lift sleeve has a first sleeve end and a second sleeve end attached together and proximate to a bottom of the sidewall to form a loop, and a portion of the sleeve extending from the second sleeve end is attached to an adjacent portion of the sidewall such that the loop maintains a substantially open position.

"Moreover, the present invention provides a method of manufacturing a bulk bag by forming a body having sidewalls, a top wall, a bottom wall and a pair of opposed lift sleeves adapted to receive lifting members for lifting the bag and contents thereof. Each lift sleeve has a first sleeve end and a second sleeve end attached together and proximate to a bottom of the sidewall to form a loop, and a portion of the sleeve extending from the second sleeve end is attached to an adjacent portion of the sidewall such that the loop maintains a substantially open position.

"Furthermore, the present invention provides a method of manufacturing a bulk bag by forming a body having sidewalls, a top wall, a bottom wall and a pair of opposed lift sleeves adapted to receive lifting members for lifting the bag and contents thereof. Each lift sleeve has a first sleeve end and a second sleeve end attached together and proximate to a bottom of the sidewall to form a loop, and a portion of the sleeve extending from the second sleeve end is attached to an adjacent portion of the sidewall such that the loop maintains a substantially open position. One or more handles are attached to the sidewalls or the top wall, each handle located proximate to a corner of the body. A spout is attached to one or more of the sidewalls, the top wall or the bottom wall to selectively access contents within the body or load contents into the body.

"The present invention is described in detail below with reference to the accompanying drawings.

BRIEF DESCRIPTION OF THE DRAWINGS
