Abstract
A sheet article dispenser includes a housing and a double-acting spring designed to urge a stack of sheet articles toward an access opening in the housing to allow only the outermost sheet to be removed one at a time. The double-acting spring includes a thin flexible panel and a resilient band. The panel has opposite ends flanking a middle section. The ends each have a pair of lateral notches at opposite edges for receiving the resilient band. The ends are flexed inwardly to form an S-shaped structure with arcuate surfaces on each side of the middle section that can deform elastically.
