Bulk bag with lift loops

Abstract

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.

What is claimed is: 
     
         1 . A bulk bag comprising:
 a bulk bag body that includes a top portion, a bottom potion and a side portion;   a plurality of lift straps with eyelets attached to the bulk bag body; and   a plurality of lift hoops secured on the eyelets of the lift straps, each lift hoop being securely linked through one of the eyelets of the lift straps so that the bulk bag can be lifted by the lift hoops.   
     
     
         2 . The bulk bag of  claim 1  wherein the lift straps are made of monofilament material. 
     
     
         3 . The bulk bag of  claim 2  wherein the lift hoops are made of multifilament material. 
     
     
         4 . The bulk bag of  claim 2  wherein the bulk bag body is made of a polypropylene woven fabric. 
     
     
         5 . The bulk bag of  claim 2  wherein the lift straps have a similar elasticity as the bulk bag body. 
     
     
         6 . The bulk bag of  claim 1  wherein 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. 
     
     
         7 . The bulk bag of  claim 6  wherein the lifts straps extend along the bottom portion of the bulk bag body to support the bulk bag body. 
     
     
         8 . The bulk bag of  claim 7  wherein the lifts straps extend along the bottom portion of the bulk bag body to form a double crossed shape. 
     
     
         9 . The bulk bag of  claim 1  wherein the eyelets of the lifts straps are located at top corners of the bulk bag body. 
     
     
         10 . The bulk bag of  claim 1  further comprising a perimeter band attached to the bulk bag body over the lift straps. 
     
     
         11 . A method of making a bulk bag, the method comprising:
 constructing a bulk bag body that includes a top portion, a bottom potion and a side portion; and   attaching a plurality of lift straps with eyelets to at least one component of the bulk bag body, including securing a plurality of lift hoops secured to the eyelets of the lift straps such that each lift hoop is securely linked through one of the eyelets of the lift straps so that the bulk bag can be lifted by the lift hoops.   
     
     
         12 . The method of  claim 11  wherein the lift straps are made of monofilament material. 
     
     
         13 . The method of  claim 12  wherein the lift hoops are made of multifilament material. 
     
     
         14 . The method of  claim 12  wherein the bulk bag body is made of a polypropylene woven fabric. 
     
     
         15 . The method of  claim 11  wherein the attaching the plurality of lift straps includes attaching the plurality of lift straps with the eyelets to at least one component of 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. 
     
     
         16 . The method of  claim 15  wherein the attaching the plurality of lift straps includes attaching the plurality of lift straps with the eyelets to at least one component of the bulk bag body bag such that the lift straps extend along the bottom portion of the bulk bag body to support the bulk bag body. 
     
     
         17 . The method of  claim 16  wherein the attaching the plurality of lift straps includes attaching the plurality of lift straps with the eyelets to at least one component of the bulk bag body such that the lifts straps extend along the bottom portion of the bulk bag body to form a double crossed shape. 
     
     
         18 . The method of  claim 11  further comprising attaching a perimeter band to the side portion of the bulk bag body over the lift straps. 
     
     
         19 . A bulk bag comprising:
 a bulk bag body that includes a top portion, a bottom potion and a side portion;   a plurality of monofilament lift straps with eyelets attached to the bulk bag body; and   a plurality of multifilament lift hoops secured on the eyelets of the monofilament lift straps, each multifilament lift hoop being securely linked through one of the eyelets of the monofilament lift straps so that the bulk bag can be lifted by the multifilament lift hoops.   
     
     
         20 . The bulk bag of  claim 19  wherein at least portions of the monofilament 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 and the monofilament lift straps extend along the bottom portion of the bulk bag body to form a double crossed shape.
