Abstract
A cap and tube device comprising a tube having an opening terminating in a nozzle with an open end and having threads for rotational engagement with a cap. Also included is a check valve in the interior of the nozzle for permitting flow of tube contents substantially only out of the tube while preventing return flow of contents into the tube. 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. Finally, the cap and tube have a cooperative ring and groove for locating the cap on the nozzle at the position where the sealing cup is in engagement with the nozzle and the ring and groove provide a signal upon full engagement of the cap and tube.
