Abstract
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.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
243 words
In the combination of a propellant storage construction and an outlet coupling member detachably interconnected to an outlet means of said construction for dispensing propellant from said construction, said outlet means comprising a locking surface means and an outlet passage in said construction and having a valve unit therein that requires a plunger thereof to be axially moved inwardly in said unit to open said unit so that propellant can be dispensed through said outlet passage to said outlet coupling member when said outlet coupling member is disposed in said outlet passage and engages and holds said plunger in its inward position while having interlocking means thereof interlocked with said locking surface means, the improvement wherein said outlet passage has a substantially cylindrical section and a frusto-conical mouth-like section intermediate said cylindrical section and said locking surface means, said outlet coupling member having a substantially flat end surface means spanning said outlet passage and engaging said plunger, said end surface means having opening means therein disposed outboard of said plunger for receiving said propellant that passes through said open valve unit, said outlet coupling member having a substantially cylindrical body portion provided with opposed ends and an annular groove intermediate said opposed ends thereof, one of said opposed ends of said body portion defining said end surface means, said body portion carrying an annular sealing ring in said annular groove, said sealing ring sealing with said outlet passage outboard of said valve unit.
Claim 2
Dependent Claim
243 words
In the combination of a propellant storage construction and an outlet coupling member detachably interconnected to an outlet means of said construction for dispensing propellant from said construction, said outlet means comprising a locking surface means and an outlet passage in said construction and having a valve unit therein that requires a plunger thereof to be axially moved inwardly in said unit to open said unit so that propellant can be dispensed through said outlet passage to said outlet coupling member when said outlet coupling member is disposed in said outlet passage and engages and holds said plunger in its inward position while having interlocking means thereof interlocked with said locking surface means, the improvement wherein said outlet passage has a substantially cylindrical section and a frusto-conical mouth-like section intermediate said cylindrical section and said locking surface means, said outlet coupling member having a substantially flat end surface means spanning said outlet passage and engaging said plunger, said end surface means having opening means therein disposed outboard of said plunger for receiving said propellant that passes through said open valve unit, said outlet coupling member having a substantially cylindrical body portion provided with opposed ends and an annular groove intermediate said opposed ends thereof, one of said opposed ends of said body portion defining said end surface means, said body portion carrying an annular sealing ring in said annular groove, said sealing ring sealing with said outlet passage outboard of said valve unit.
Claim 3
Dependent Claim
34 words
A combination as set forth in claim 1 wherein said opening means of said end surface means of said outlet coupling member comprise a plurality of spaced apart openings in said end surface means.
Claim 4
Dependent Claim
36 words
A combination as set forth in claim 2 wherein said openings in said end surface means of said outlet coupling member are disposed in a circular array that is substantially concentrically disposed relative to said plunger.
Claim 5
Dependent Claim
67 words
A combination as set forth in claim 3 wherein said end surface means of said outlet coupling member comprises an outer annular portion and an inner star-like portion having a central section and a plurality of points radially extending from said section to said annular portion whereby said openings are defined between said points and between said annular portion and said central section of said star-like portion.
Claim 6
Dependent Claim
56 words
A combination as set forth in claim 4 wherein one of said opposed ends of said body portion is interrupted by a stepped passage whereby said stepped passage defines said annular portion at said one end of said body portion, said star-like portion being separate from said body portion and being disposed in said stepped passage.
Claim 7
Dependent Claim
44 words
A combination as set forth in claim 1 wherein said frusto-conical section has opposed large and small bases, said small base being adjacent said cylindrical section and having the same diameter as said cylindrical section, said large base being adjacent said locking surface means.
Claim 8
Dependent Claim
28 words
A combination as set forth in claim 1 wherein said interlocking means of said body portion of said coupling member comprises a pair of outwardly directed wing-like parts.
Claim 9
Dependent Claim
29 words
A combination as set forth in claim 7 wherein said wing-like parts of said body portion of said outlet coupling member extend in opposite directions from said body portion.
