Abstract: A closure mechanism is disclosed for a package for liquids where the package includes a container for housing a liquid and having opposing surfaces defining a discharge opening exposing a container interior. The closure mechanism inlcudes an intermediate member mounted on the container and covering the discharge opening. The intermediate member has a pour spout extending from a first end to a second end. A wall surrounds the pour spout and is spaced therefrom to define a liquid retaining volume. A floor is disposed within the volume adjacent the first end of the spout and having a floor opening providing liquid flow communication between the liquid retaining volume and the container interior. A cap is provided removably connected to the package and sized to cover the spout and the liquid retaining volume. A closure plate is provided for blocking flow of liquid through the floor opening when the cap is disconnected from the package.
