Abstract of the Disclosure A novel closure and container assembly is disclosed which provides for the definite and positive positioning of the closure on the container in a predetermined semi-open positionment. The container is provided with a rim portion which extends within a plane perpendicular to the axis of the cylindrical neck portion of the container and has a tapered surface lying within a cone concentric with such axis, whereas the closure is also provided with a tapered surface lying within a surface of a cone concentric with such axis so that upon the threading of the closure onto the container the surfaces engage each other within the surface of a cone lying concentric to the axis of the cylindrical neck portion and create a binding action which positions the closure in its predetermined semi-open positionment on the container. A further twisting of the closure allows the closure to sealably engage the container.
