Abstract: Collapsible discs move towards or away from each other in embodiments of the disclosed technology by changing the angle of flanges which connect the two discs together. The flanges connect to each respective disc by way of one of a living hinge and/or a slidable hinge where a slidable hinge is one which includes a crossbeam wider than a body of the flange which slides within a cavity of one of the discs. This can be accomplished with two flanges which move in opposite directions, or two sets of two flanges, each set offset 90 degrees from one another. The two flanges can also be arranged such that one passes through a portal in the other or arranged side by side.

Abstract: Two circular discs are collapsible towards each other and expandable away from each other by way of rotatable hinge(s) situated there-between which move the circular discs towards and away from each other. The rotatable hinge(s) are connected to the circular discs by way of living hinges. The rotable hinge(s) may be surrounded by a cloth or plastic cover which can be non-resilient or resilient, such a cover further connected in a circular manner to each disc.
