The present invention relates to a liner for use in a box-like cargo container for transportation of powder, granular or other flowable products, said liner comprising top and bottom walls, two side walls and first and second end wall portions, a discharge opening at the lower portion of said first end wall through which the contents of the liner are discharged, displacement means for guiding the contents towards said discharge opening, said displacement means comprising at least one inflatable, flexible bag having an essentially triangular or trapezoid shape substantively abutting said first end wall, and a first essentially triangular or trapezoid portion supporting the outside surface of the floor and a second essentially triangular portion supporting the adjacent side wall portion of the liner, said bag comprising three corners positioned substantively at the edge of the end wall and the side wall portion, the end wall and the bottom wall portion, and the side wall and the bottom wall portion. The flexible bags are preferably attached to the outside surface of the liner by a number of individual double adhesive strips, and the upper corner portion of the flexible bag is provided with a flexible inflation tube for inflation of the flexible bag with pressurized air causing the inflation to advance from the upper portion and downwards in the bag as the amount of material in the liner is reduced.Since an inflatable bag according to the invention has an essentially triangular shape aligned with the end wall and is attached to the liner along the edge of the side wall and the floor of the liner, the material is not lifted but rather pushed sideways away from the side wall of the corner region of the container. The stress implied in the bag as well as in the liner is thereby reduced considerably.

1. A liner for use in a box-like cargo container for transportation of powder, granular or other flowable products, said liner comprising:top and bottom walls, first and second side walls and first and second end wall portions; a discharge opening at the lower portion of said first end wall through which the contents of the liner are discharged; displacement means for guiding the contents towards said discharge opening; said displacement means comprising an inflatable, flexible bag having an essentially triangular or trapezoid shape, wherein the inflatable bag comprises two essentially flexible sheets, said sheets being secured to each other in a gas-tight manner along their edges forming an interior space that can be increased in volume by inflation with pressurized air, said bag having a first edge substantively abutting said first end wall, and a first portion supporting the bottom wall and a second portion supporting an adjacent side wall portion of the liner; said bag comprising three corners positioned substantively at the edge of the first end wall and the first side wall portion, the first end wall and the bottom wall portion, and the first side wall and the bottom wall portion, wherein the upper corner portion of the flexible bag is provided with a flexible inflation tube for inflation of the flexible bag with pressurized air causing the inflation to advance from the upper portion and downwards in the bag as the amount of material in the liner is reduced, wherein the flexible bag, when deflated, is folded against the bottom wall portion and the first or second side wall portion of the liner.
