A pump type dispenser having a bellows or diaphragm formed by a plurality of hollow ribs and valleys therebetween extending between a peripheral skirt and a central barrel. The valleys are inclined downwardly from the skirt to the barrel insuring the strength and resiliency of the diaphragm to return the diaphragm to its relaxed position after repeated activation.
