Abstract
Abstract An aseptic sample fitting for a fluid enclosure includes a disposable tapered plug removably held in a neck with its inner end substantially flush with the enclosure interior. The plug includes a rigid core that is provided with circumferentially arrayed convergent sampling needle guide channels, and a cupshaped self-healing pressure seal member. A sanitary seal member of flexible sheet material protects the outer ends of the guide channels and also indicates the location and used or unused state of each channel. The inner end of the neck opening defines a feathered shroud which extends across a rounded edge of the plug to minimize exposed area and improve surface configuration. Barrier ridges surround each guide channel at the interface of the core and pressure seal member to prevent movement of material from one channel to another. A retainer ring bears against a holding flange on the core to hold the plug in place.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
162 words
A sample fitting for a fluid enclosure, said fitting comprising: a neck that defines an opening of substantial axial length that leads to the interior of the enclosure and that is axially tapered to be smaller at its inner end; a tapered plug removably received in the opening with a close fit and with its inner end substantially flush with the enclosure interior, the plug including a rigid internal core having an inner end that extends into and is substantially spaced from the sides and inner end of the opening and that is provided with at least one needle guide channel extending axially therethrough, the plug also including an external cup-shaped pressure seal member of a compressible, pierceable, self-healing material that receives and is tightly secured to the inner end of the core and that sealingly engages the sides of the opening and defines the inner end surface of the plug; and a releasable retainer to hold the plug in the opening.
Claim 2
Dependent Claim
162 words
A sample fitting for a fluid enclosure, said fitting comprising: a neck that defines an opening of substantial axial length that leads to the interior of the enclosure and that is axially tapered to be smaller at its inner end; a tapered plug removably received in the opening with a close fit and with its inner end substantially flush with the enclosure interior, the plug including a rigid internal core having an inner end that extends into and is substantially spaced from the sides and inner end of the opening and that is provided with at least one needle guide channel extending axially therethrough, the plug also including an external cup-shaped pressure seal member of a compressible, pierceable, self-healing material that receives and is tightly secured to the inner end of the core and that sealingly engages the sides of the opening and defines the inner end surface of the plug; and a releasable retainer to hold the plug in the opening.
Claim 3
Dependent Claim
68 words
A sample fitting according to claim 1, wherein: the neck extends outwardly from the enclosure and is externally threaded; and the core defines an outwardly extending annular holding flange that extends over and bears against the outer end of the neck; and the retainer comprises a ring removably threaded on the neck that has an inwardly extending annular retainer flange that overhangs and bears agains the holding flange.
Claim 4
Dependent Claim
23 words
A sample fitting according to claim 1, wherein: the core is provided with a plurality of separate needle guide channels extending axially therethrough.
Claim 5
Dependent Claim
28 words
A sample fitting according to claim 3, wherein: there is a sanitary seal member of flexible, pierceable sheet material covering the outer ends of the needle guide channels.
Claim 6
Dependent Claim
38 words
A sample fitting according to claim 3, wherein: the interface between the inner end surface of the core and the pressure seal member is shaped to define upstanding barriers surrounding the inner end of the needle guide channels.
Claim 7
Dependent Claim
48 words
A sample fitting according to claim 3, wherein: the needle guide channels are circumferentially arrayed and are conical with radially innermost edges that are parallel to the longitudinal axis of the core and radially outermost edges that converge toward the center of the inner end of the core.
Claim 8
Dependent Claim
44 words
A sample fitting according to claim 6, wherein: the edge surrounding the inner end surface of the plug is rounded; and the inner end of the opening is shaped to define an annular feathered shroud that mates with and extends across the rounded edge.
Claim 9
Dependent Claim
28 words
A sample fitting according to claim 7, wherein: there is a sanitary seal member of flexible, pierceable sheet material covering the outer ends of the needle guide channels.
Claim 10
Dependent Claim
38 words
A sample fitting according to claim 8, wherein: the interface between the inner end surface of the core and the pressure seal member is shaped to define upstanding barriers surrounding the inner ends of the needle guide channels.
Claim 11
Dependent Claim
68 words
A sample fitting according to claim 9, wherein: the neck extends outwardly from the enclosure and is externally threaded; and the core defines an outwardly extending annular holding flange that extends over and bears against the outer end of the neck; and the retainer comprises a ring removably threaded on the neck that has an inwardly extending annular retainer flange that overhangs and bears against the holding flange.
Claim 12
Dependent Claim
21 words
A sample fitting according to claim 10, wherein: the core is provided with a centrally located, outwardly opening threadEd pullout bore.
