DRAIN CONNECTOR FOR SUBSTANCE PROCESSING RECEPTACLE
A drain connector arranged for mounting to a tank or bag having an interior volume includes a drain flange defining a bore having an inner diameter, and a hollow body having at least an upper portion with a maximum outer diameter that is no greater than the inner diameter of the bore and arranged to convey fluid to the interior volume, with at least one circumferential sealing element between the drain flange and hollow body, with the drain flange including a body extending outside the interior volume and including at least one retaining element arranged to retain the hollow body in a position. A drain flange may include multiple bores for receiving multiple hollow bodies, with each hollow body including at least one circumferential sealing element. One or more drain flanges may be generic for use with hollow bodies of different characteristics to enable fabrication of a processing container or bag by affixing one or more drain flanges, and then selecting among the plurality of different hollow bodies for insertion into the drain flange(s).
1 - 14 . (canceled)
15 . A method of fabricating a processing container or processing bag defining an interior volume, the method comprising:
mounting at least one drain flange to at least one wall of the processing container or processing bag, the at least one drain flange comprising a radially extending flange lip and defining a bore having an inner diameter;
selecting at least one hollow body from a plurality of hollow bodies compatible with the at least one drain flange, the at least one hollow body having at least one end with a maximum outer diameter that is no larger than the inner diameter of the bore, and being arranged to convey fluid to or from the interior volume, wherein the plurality of hollow bodies comprises hollow bodies that differ with respect to at least one of core size, connection type, connection size, hollow body material type, circumferential sealing material type, and presence or absence of an end opening; and
inserting the selected at least one hollow body into the bore of the at least one drain flange.
16 . The method of claim 15 , wherein the selected at least one hollow body is inserted into the bore of the at least one drain flange from outside of the processing container or processing bag in a direction toward an interior volume of the processing container or processing bag.
17 . The method of claim 15 , wherein the plurality of hollow bodies comprises at least one hollow plunger and at least one hollow port.
18 . The method of any claim 15 , further comprising:
sterilizing the processing container or processing bag, the at least one drain flange, and the at least one selected hollow body, and
packaging the processing container or processing bag, the at least one drain flange, and the at least one selected hollow body in a package adapted to maintain sterile and/or substantially contaminant-free conditions within the package.
19 - 22 . (canceled)
23 . The method of claim 15 , wherein the plurality of hollow bodies comprises hollow bodies that differ with respect to core size.
24 . The method of claim 15 , wherein the plurality of hollow bodies comprises hollow bodies that differ with respect to connection size
25 . The method of claim 15 wherein the plurality of hollow bodies comprises hollow bodies that differ with respect to connection type.
26 . The method of claim 15 , wherein the plurality of hollow bodies comprises hollow bodies that differ with respect to hollow body material type.
27 . The method of claim 15 , wherein the plurality of hollow bodies comprises hollow bodies that differ with respect to circumferential sealing material type.
28 . The method of claim 15 , wherein the drain flange and the plurality of hollow bodies comprise at least one polymeric material.
29 . The method of claim 16 , further comprising:
sterilizing the processing container or processing bag, the at least one drain flange, and the at least one selected hollow body, and
packaging the processing container or processing bag, the at least one drain flange, and the at least one selected hollow body in a package adapted to maintain sterile and/or substantially contaminant-free conditions within the package.
