Abstract
Abstract A one-piece plastic cylindrical closure for a container that is useful as a measuring cup. The closure has an integral internal skirt member projecting into the neck of the container which functions as a self-draining member to return residual liquid remaining in the closure to the container and to prevent this liquid from reaching the threaded exterior neck portion of the container.
