Abstract
Abstract An apparatus for quickly disconnecting two tubular flow lines (30,31) comprising first and second units (25,26) including first (27) and second (28) tubular members which have mutually tapering interengagement surfaces ((27a,28a), and end terminals (27b,28b), the members respectively associated with the two flow lines and the members being axially interfittable; the first and second units (25,26) including first and second protectors (33,34) respectively associated with and extending about the end terminals, the protectors positioned to radially and axially overlap when the members are brought into interfitting interengagement at the tapering surfaces.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
218 words
A shrouded tubing interface for quickly connecting, disconnecting and avoiding contamination of first and second fluid flow lines, comprising: a first connector having a first tubular member defining an open flow path with a first fluid flow line, said first tubular member defining a first end terminal and an outer annular surface, said first connector further including a first wall member extending radially outward of and axially beyond said first end terminal of said first tubular member to form a physical barrier to prevent inadvertent contact with said first end terminal so as to prevent contamination thereof; a second connector having a second tubular member defining an open flow path with a second fluid flow line, said second tubular member defining a second end terminal and an aperture extending axially therethrough, said second connector further including a second wall member extending radially outward of and axially beyond said second end terminal of said second tubular member to form a physical barrier to prevent inadvertent contact with said second end terminal so as to prevent contamination thereof; and means formed on said first and second wall members for releasably connecting said first and second connectors, said outer surface of said first tubular member being slidably receivable into said aperture when said first connector is connected to said second connector.
Claim 2
Dependent Claim
40 words
The device of Claim 1 wherein said first and second wall members comprise skirts having generally tubular configurations, said tubular skirts being adapted to extend in co-axial and concentric relation when said first connector is connected to said second connector.
Claim 3
Dependent Claim
71 words
The device of Claim 2 wherein said connecting means comprises male threads formed upon a portion of said first wall member and female threads disposed within a portion of said second wall member, said female threads being sized and configured to receive said male threads so as to retain said first tubular member in engagement with said second tubular member when said first tubular member is slidably received into said aperture.
Claim 4
Dependent Claim
39 words
The device of Claim 3 wherein said first connector further includes a first extension for telescopically receiving said first fluid flow line and said second connector further includes a second extension for telescopically receiving said second fluid flow line.
Claim 5
Dependent Claim
24 words
The device of Claim 4 wherein said first connector further includes a third extension extending radially outward of and axially overlapping said second extension.
Claim 6
Dependent Claim
43 words
The device of Claim 5 wherein said second wall member and said third extension include outer surfaces having a plurality of grip edges formed thereon, said grip edges being adapted to aid in the connection of said first connector to said second connector.
Claim 7
Dependent Claim
26 words
The device of Claim 1 wherein the outer surface of said first tubular member and the aperture of said second tubular member have mutually tapered configurations.
Claim 8
Dependent Claim
36 words
The device of Claim 3 wherein said second wall member is rotatably connected to said first connector for allowing said female threads to be threadably engaged to said male threads without rotating said second tubular member.
Claim 9
Dependent Claim
49 words
The device of Claim 4 wherein said first extension includes an outer surface having a barbed configuration for being frictionally retained within said first fluid flow line and said second extension includes an outer surface having a barbed configuration for being frictionally retained within said second fluid flow line.
