ABSTRACT:
A container of variable volume is disclosed consisting of parallel spaced polygon surfaces peripherally interconnected via triangular surfaces which join one another. The triangular surfaces are shaped and interconnected such that when the two polygons move relative to one another they undergo a rotational movement relative to one another. The triangular surfaces may, in place of having their ends attached to the polygons, be attached to a further set of triangular surfaces whereby the stack height of the container may be incrementally increased. Fold-up containers as herein disclosed may be used as ink supply containers for ink recording devices.
