ABSTRACT:
A container for receiving and retaining contents under pressure is provided with an improved valve structure to prevent contamination of the discharge valve during the filling operation. The valve structure includes a check valve which is opened when filling the container, and a sealing element which engages and surrounds a filling tube thereby preventing the contents from reaching the discharge valve. Additionally, purging of the discharge mechanism will clean the same of any residue that may be found therein.
