<p>A bulk liquid container (1) has two expansible liquid carrying compartments which can be independently filled, if desired with different liquids. A first compartment is bounded by a rigid end wall (2), an extensible first sleeve (6) of oil-resisting rubber or the like formed with a series of preformed corrugations, and a first rigid member (5) movable within rigid outer walls (3) and can be filled or emptied by means of a valve (10) and de-aired by means of another valve (11). The second compartment is bounded by the first rigid member (5), an extensible second sleeve (7) also provided with a series of preformed corrugations, and a second rigid member (4) which can either slide within the rigid outer walls or can comprise a fixed end wall.</p> |
