The cap is sized to engaged the nozzle at its open end and has a closed terminal end having a first inwardly facing axially centered locating cup for engagement with the open end of the nozzle, and a second inwardly facing axially centered sealing cup for engagement with the open end of the nozzle to form a seal in the nozzle open end.
