Abstract
Abstract A plastic dispenser cap has a closure, integrally attached thereto by a continuous hinge, for blocking holes formed in the cap. When shut, the lower surface of the closure is flush with the upper surface of the cap, resulting in an article of minimal height. When assembled to standard bottles, a stackable assembly results.
