Abstract
A pressurized refill and a method for pressurizing a refill are provided. The refill has a plug secured at an end of the refill having multiple seals between the plug and an interior wall of the refill. A valve extends through a channel of the plug allowing pressurized gas to be forced into an interior of the refill to pressurize or re-pressurize the interior of the refill. A spring loaded stem maintains the valve in a closed and sealed position when pressurization is not being effected.
