Patent ID: 7320408

Claim:
A bulk material cargo container liner for use within a bulk material cargo container having rear door structures, comprising: a bulk material cargo container liner having a substantially rectangular parallelepiped structure when erected for disposition within a bulk material cargo container and therefore comprising a front wall member, a pair of side wall members, a ceiling member, a floor member, and a rear wall member having a vertically oriented elevational height extent; and means, having a vertically oriented, linearly extending edge portion defining a vertically oriented length dimension, fixedly connected to an interior surface portion of said floor member and to an interior surface portion of said rear wall member such that said vertically oriented, linearly extending edge portion extends substantially the entire length of said vertically oriented elevational height extent of said rear wall member for impressing restraint forces, along first linear loci, upon said rear wall member of said bulk material cargo container liner which will effectively reduce the forces normally imposed upon said rear wall member of said bulk material cargo container liner, by means of hydrostatic head load forces generated as a result of bulk cargo material being charged into said bulk material cargo container liner, so as to thereby prevent said rear wall member of said bulk material cargo container liner from undergoing outward bulging.
