Closure cap including film portion

Abstract

A closure cap adapted to be removably retained on a container can include a cap portion and a film portion. The cap portion can include an opening adapted to permit flow from an interior of the container to an exterior of the container when the closure cap is retained on the container. The film portion can be adapted to prohibit flow through the opening and can be positionable to permit flow through at least a portion of the opening when the closure cap is retained on the container. A drinking straw can be introduced into the opening to permit flow from the interior to the exterior of the closure cap.
