Abstract

An unequivocal bottom delivery package with a self sealing valve for storing and dispensing a fluid material. The package has a shipping configuration in which a shipping cap is located over the self sealing valve to provide leakage resistance during shipment. Upon receipt it is obvious that operation of the package first necessitates removal of the shipping cap. Removal of the shipping cap transforms the package into a dispensing configuration. The dispensing configuration provides easy one step dispensing and makes it obvious that the container is intended to be stored with the self sealing valve between uses. A travel cap is provided for placement over the self sealing valve, transforming the package into a traveling configuration, which provides leakage resistance during subsequent transportation. It is obvious the package is not intended to be placed into the travelling configuration between every use.
