US 2013/0092706 A1 · PRESSURIZED LINER

Abstract

A pressurized liner (10) is disclosed for use with a bulk container. The pressurized liner has a central band (12), two inner caps (13), and two outer caps (14). Each inner cap has an end wall (20) and four peripheral side walls (21). Each outer cap has an end wall (22) and four peripheral side walls (23). The central band and inner caps define a central compartment (33) which has an inlet port (34) and an outlet port (36). Each adjoining pair of inner caps and outer caps define inflatable side compartments (39) coupled to opposite sides of the central compartment. Each inflatable side compartment has a pressurized air port (40) to allow inflation and deflation of the side compartment. The inner caps have a lateral depth (d1) generally equal to or greater than a lateral depth (d2) of the outer caps.

Dependent claims

A pressurized liner for use with an intermediate bulk material container, said pressurized liner comprising,

a tubular central band having at least one content port and at least one open end defined by a peripheral edge;
at least one inner cap sealed to said tubular central band open end, said inner cap having an inner cap end wall and peripheral inner cap side walls extending from said inner cap end wall, and
at least one outer cap sealed to said tubular central band open end, said outer cap having an outer cap end wall and peripheral outer cap side walls extending from said outer cap end wall, said outer cap having an air inlet port extending therethrough;
said inner cap and said outer cap defining an expandable pressure compartment therebetween in fluid communication with said outer cap air inlet port,
whereby the inflation of the expandable pressure compartment moves the inner cap to a position within the central band.
