ABSTRACT:
A refillable container includes a filling valve, and a pressurization station having housing at which a needle is coupled to a compressor. The needle includes an enlarged frustoconical head, a reduced diameter neck, and a larger diameter base. The filling valve has an upper split portion, a frustoconical section expanding downward and terminating in a barb, and a lower flared flange, and defines an interior space having a first portion sized to accommodate the head of the needle, a reduced diameter neck portion, and a flared third portion providing an entrance for the needle. Upon compressor actuation, air is forced into the valve and causes the bills of the valve to flutter open to pressurize the container. As pressure within the container increases, force against the valve from within the container increases, locking the container on the needle. The container may be guided onto the needle with minimal effort.
