Abstract
A dispensing package is provided for fluid products, such as liquids, pastes, powders and the like. The package comprises a container in which the product is packaged, and a self-sealing dispensing valve which automatically opens and closes in response to the application and removal of a predetermined threshold pressure. A removable closure may be provided to cover the dispensing valve and prevent inadvertent discharge of the product during transport, storage and other similar conditions.
