Flexible container liner wringing device and liner
A liner (L) has a liner body ( 11 ) with a front wall ( 12 ), rear wall ( 16 ), bottom wall ( 13 ), a top wall ( 14 ). The top wall also includes a tubular excess liner material or chute ( 19 ) located close to the rear wall and which includes a filling fitment ( 20 ) with a fitment cap ( 21 ). The liner also has a cylindrical, hose content inlet/outlet port or bottom fitment ( 23 ). The liner may include a gap-filler or filler strip ( 90 ) of foam material extending outwardly from a position closely adjacent the outlet fitment. The filler strip is mounted to the front wall and/or top wall. The filler strip may taper so that at least a majority of the strip's longitudinal length or height so as to increase in its lateral width as it approaches the outlet fitment, thereby increasing the material volume of strip material.
1. A liner for use with an intermediate bulk material container, said liner comprising,
a liner body having a top wall, a bottom wall, and a plurality of side walls extending between said top wall and said bottom wall;
an inlet fitment coupled to said top wall;
an outlet fitment coupled to a first said side wall of said plurality of side walls, and
a gap filler coupled to said first side wall of said plurality of side walls in a position above said outlet fitment and to said top wall, said gap filler being a length of flexible material.
2. The liner of claim 1 wherein said gap filler has a longitudinal length and a lateral width which decreases along at least a majority of said longitudinal length from said outlet fitment towards said top wall.
3. The liner of claim 1 wherein said gap filler is a foam material.
4. The liner of claim 3 wherein said foam material is a closed cell polyethylene material.
5. The liner of claim 1 wherein said plurality of side walls includes a front wall, wherein said outlet fitment is mounted to said front wall, and wherein said gap filler is coupled to said front wall.
6. The liner of claim 5 wherein said gap filler extends from a position directly over and closely adjacent said outlet fitment towards said top wall.
7. A liner for use with an intermediate bulk material container, said liner comprising,
a liner body having a top wall, a bottom wall, and a tubular side wall extending between said top wall and said bottom wall;
an outlet fitment coupled to said tubular side wall, and
a material volume increasing gap filler coupled to said top wall in a position above said outlet fitment, said gap filler having a longitudinal length and a lateral width for increasing the material volume of at least select portions of the liner in a gathered configuration,
wherein said lateral width of said material volume increasing gap filler varies along at least a majority of said longitudinal length of said material volume increasing gap filler.
8. The liner of claim 7 wherein said lateral width of said material volume increasing gap filler decreases along at least a majority of said longitudinal length of said material volume increasing gap filler.
9. The liner of claim 7 wherein said material volume increasing gap filler is a foam material.
10. The liner of claim 7 wherein said material volume increasing gap filler is also coupled to said tubular side wall.
11. The liner of claim 10 wherein said lateral width of said material volume increasing gap filler decreases along at least a majority of said longitudinal length as said material volume increasing gap filler extends along said tubular side wall.
12. The liner of claim 10 wherein said material volume increasing gap filler extends from a position directly over and closely adjacent said outlet fitment towards said top wall.
13. A liner for use with an intermediate bulk material container, said liner comprising,
a liner body having a generally rectangular prism configuration having a top wall;
an outlet fitment coupled to said liner body, and
a gap filler coupled to said liner body, said gap filler being a length of flexible material mounted to and extending across at least a portion of said top wall,
wherein said gap filler has a longitudinal length and a lateral width which varies along at least a majority of said gap filler length.
14. The liner of claim 13 wherein said gap filler is a foam material.
15. The liner of claim 14 wherein said foam material is a closed cell polyethylene material.
16. The liner of claim 13 wherein said liner body includes a front wall, wherein said outlet fitment is mounted to said front wall, and wherein said gap filler is also coupled to said front wall.
17. The liner of claim 16 wherein said gap filler extends from a position directly over and closely adjacent said outlet fitment towards said top wall.
