ABSTRACT:
A resilient liner for mounting within a hopper type receptacle which receives and discharges flowable bulk particulate material. The liner is comprised of one or more resilient panels each having a fluid tight envelope with a top and bottom sheet held in substantially spaced parallel relationship by a series of internal transverse seams or walls or by a layer of open celled foam when the internal pressure of the envelope is at least slightly higher than the ambient pressure outside the envelope. The panels are sufficiently resilient, that particles or chunks of material passing through the hopper striking the top of the envelope cause undulation of the top of the envelope which aids in maintaining the constant flow of particulate material through the receptacle. The panels may be protected by a wear resistant cover loosely covering the panels or integral with the panels.
