Abstract
An improved flexible semi-bulk container utilizing rigid panels associated with the side walls of the flexible container to provide rigidity and enable the container to stand alone when filled with fluidized material such as fluidized solids, semi-solids, slurries and liquids.
Claims18
An improved flexible semi-bulk material container suitable for use with fluidized materials such as fluidized solids, semi-solids, slurry and liquids and having adequate stability to stand alone, said container comprising:
- a flexible body portion formed with side walls, a top wall and a bottom wall;
- each of said side walls being double-layer side walls sealed at the side edges thereof to provide a space therebetween;
- access spouts in the body portion to fill and empty the body portion with fluidized materials;
- and
- rigid panels associated with at least two opposing ones of the body side walls, a separate one of said rigid panels inserted in said space in at least two of said opposing double-layer side walls to provide rigidity sufficient to impart adequate stability to the flexible body portion to enable it to stand alone on said bottom wall when filled with a fluidized material.
An improved flexible semi-bulk material container suitable for use with fluidized materials such as fluidized solids, semi-solids, slurry and liquids and having adequate stability to stand alone comprising:
- a flexible body portion formed with side walls, a top wall and a bottom wall;
- access spouts in the body portion to fill and empty the body portion with fluidized materials;
- a rigid four-sided sleeve inserted within said flexible body portion to provide rigidity sufficient to impart adequate stability to the flexible body portion to enable it to stand alone on said bottom wall when filled with a fluidized material;
- said sleeve comprising a continuous rectangular rigid panel scored across its width at spaced locations to form a four-sided sleeve when folded along said score lines, two opposing sides of said sleeve having score lines on the inside surface thereof to enable folding of said container with the sleeve therein for storage and handling;
- and
- said four-sided sleeve imparting said rigidity and stability to said container when filled with a fluidized material.
A method for stabilizing a flexible semi-bulk material container when filled with a fluidized material such as fluidized solids, semi-solids, slurry and liquids so as to enable the filled container to stand alone, said method comprising the steps of:
- forming a flexible body portion with side walls, a top wall and a bottom wall;
- each of said side walls being double-layer side walls sealed at the side edges thereof to provide a space therebetween;
- forming access spouts in the body portion to fill and empty the body portion with fluidized materials;
- and
- inserting a separate one of said rigid panels in said space in at least two of said opposing double-layer side walls to provide rigidity sufficient to impart adequate stability to the flexible body portion to enable it to stand alone on said bottom wall when filled with a fluidized material.
A method for stabilizing a flexible semi-bulk material container when filled with a fluidized material such as fluidized solids, semi-solids, slurry and liquids so as to enable the filled container to stand alone, said method comprising the steps of:
- forming a flexible body portion with side walls, a top wall and a bottom wall;
- forming access spouts in the body portion to fill and empty said body portion with fluidized materials;
- forming a sleeve from a continuous rectangular panel scored across its width at spaced locations to form a four-sided sleeve when folded along said score lines;
- inserting said four-sided sleeve within said flexible container to provide said stability to the container when filled with a fluidized material;
- and
- forming additional score lines in at least two opposing sides of said sleeve on the inside surface thereof to enable folding of said container with the sleeve therein for storage and handling, said four-sided sleeve imparting rigidity and stability to said container when filled with a fluidized material.
