Abstract
The combination of a propellant storage construction and an outlet coupling member detachably interconnected to an outlet of the construction for dispensing propellant from the construction, the outlet comprising a locking surface and an outlet passage in the construction and having a valve unit therein that requires a plunger thereof to be axially moved inwardly in the unit to open the unit so that propellant can be dispensed through the outlet passage to the outlet coupling member when the outlet coupling member is disposed in the outlet passage and engages and holds the plunger in its inward position while interlocking with the locking surface. The outlet passage has a substantially cylindrical section and a frusto-conical mouth-like section intermediate the cylindrical section and the locking surface, the outlet coupling member having a substantially flat end surface spanning the outlet passage and engaging the plunger and the end surface having an opening therein disposed outboard of the plunger for receiving the propellant that passes through the open valve unit. The outlet coupling member has a substantially cylindrical body portion provided with opposed ends and an annular groove intermediate the opposed ends thereof. One of the opposed ends of the body portion defines the end surface thereof. The body portion carries an annular sealing ring in the annular groove thereof that seals with the outlet passage outboard of the valve unit.
