Abstract
A paper roll support assembly is provided with a collapsible spindle with distal ends to be received in a pair of bracket receptacles. Product packaging is sized to receive the collapsible spindle only in a collapsed state of the spindle to minimize an overall size. The collapsible spindle is provided with an outer spindle member, an open end spaced apart from the distal end, and a cavity formed therein with a first diameter. An inner spindle member is provided with a proximal end spaced apart from the distal end with an outer diameter sized to be received within the cavity for translation and rotation relative to the outer spindle. A first retainer is oriented in the cavity in cooperation with a second retainer oriented on the inner spindle member such that extension is prevented in a first rotational orientation and extension is permitted in a second rotational orientation.
