Document Type and Number:
Japanese Patent JP3074280
Kind Code:
B2
Abstract:
PURPOSE:To permit a easy and rapid complete unloading of cargo by a method wherein a canvas or woven cloth is laid on the bottom part inside a flexible outer bag, a gas jet opening is provided underneath this woven cloth and an angle formed between the cord for reinforcing a flexible inner bag and the axis of the inner bag is made equal to or slightly smaller than an angle of friction. CONSTITUTION:A flexible outer bag 1 is formed of the rubber or synthetic resin having an embedded reinforcement layer consisting of at least one sheet of canvas or the like. The outer bag 1 is provided near its bottom part with a pressure gas introducing opening 8 open on the rear side of an inner bag 2 at one longitudinal end thereof and cargo discharge opening 9 at the opposing longitudinal end thereof. The reinforcing cord for forming the reinforcing layer of the flexible inner bag 2 having its opening part attached airtight to the central part of the flexible outer bag 1 in the longitudinal direction is extended axially of the inner bag, preferably at an angle of friction. To bring the inner bag 2 into close contact with the inner surface of the outer bag upon reverse displacement, the reinforcing cord is extended in such a direction as to reduce the angle of friction slightly.
