Abstract
Abstract A multi-functional, environmentally-oriented one-piece container closure panel has a peripheral rib adapted to removably engage the lip of a container end. The closure panel is slidably rotatable on the lip such that an opening in the closure panel may be variably positioned in alignment with a push-in opening in the container end to control the dispensing of container contents. When removed, the one-piece container closure may be disposed of separately, allowing recycling of reusable container materials or disposal of biodegradable container materials. Because disposed of separately, the container closure may be of any suitable material appropriate for the application, while different reusable or biodegradable materials may be used for the container.
