Abstract
Abstract A dripless closure for a product container characterized by a cap movable on a body member, where the cap has a passageway or opening along the periphery of the upper surface thereof which selectively communicates with the contents of the container. The upper surface of the closure remains free of the product, and, further, the closure eliminates the necessity of the center post commonly found on containers presently in use.
