Abstract
A dispensing pump for liquids, viscous materials, foams, gels, etc. includes a resilient plastic skirt spring so that the entire pump can be more easily recycled. The skirt spring comprises a plurality of concentric nesting rings sequentially decreasing in diameter from a base ring to a top ring to form a conical shape wherein adjacent rings are interconnected by spaced bridge segments and the bridge segments are staggered at each sequential ring.
