A closure for use with an associated container having a finish with an external securing member formed thereon, includes a closure cap having an enlarged top wall portion defining an outermost edge and an annular skirt portion depending from the top wall portion inwardly of the outermost edge. The skirt portion has an outer wall and an inner wall having an internal securing member engageable with the container external securing member. The closure cap includes a plurality of parallel, spaced apart, tapered ribs. At least some of the ribs extend between the top wall portion and the skirt outer wall. Each rib defines an outer edge and tapers inwardly or thins from the closure cap to the outer edge to define a region adjacent to a juncture of each rib and the closure cap having a cross-sectional area that is greater than a cross-sectional area at the outer edge of each respective rib. The ribs can taper in one or more directions. The ribs are separated from one another by parallel recessed regions.
