ABSTRACT:
Mounting assemblies for toilet tissue rolls and the like comprised of tapered annular-shaped rims force-fittingly received within the hollow cylindrical core of a toilet tissue roll. A centrally located trunion portion is joined to the aforesaid rim by radially aligned spanning ribs having a width, thickness, geometry, and being of a plastic material which characteristics cooperate to provide flexibility of the mounting assembly to enable it to collapse into the core interior and, due to the "plastic memory" of the support ribs, cause the assembly to resume its normal expanded state upon the removal of the forces responsible for collapsing thereof, the trunions being adapted to be substantially telescopingly received within cooperating opening provided in a conventional receptacle, a pair of such assemblies cooperatively providing a "disposable spindle".
