RESILIENT LINER FOR PARTICULATE BULK CARGO RECEPTACLES ABSTRACT OF THE DISCLOSURE A resilient liner for mounting within a hopper type receptacle 6 which receives and discharges flowable bulk particu- late material. The liner is comprised of one or more resilient panels 11 each having a fluid tight envelope 14 with a top and bottom sheet 15 and 16 held in substantially spaced parallel relationship by a series of internal transverse seams or walls 28 or by a layer of open celled foam 17 when the internal pressure of the envelope is at least slightly higher than the ambient pressure outside the envelope. The panels 17 are sufficiently resilient, that particles or chunks of material passing through the hopper 1 striking the top of the envelope 14 cause undula- tion of the top of the envelope which aids in maintaining the constant flow of particulate material through the receptacle 6. The panels 17 may be protected by a wear resistant cover 36 loosely covering the panels 17 or integral with the panels.
