Vented fluid transfer lid

Abstract

A vented transfer lid includes an inner collar projecting from a top panel of the transfer lid and having an outer circumferential surface having a texturized EDM surface finish. In some example forms, an interior surface of the top panel includes a texturized EDM surface finish. In example forms, the transfer lid includes a transfer port wherein at least a portion of an interior surface of the transfer port includes a texturized EDM surface finish. In other embodiments, at least a portion of the vented transfer lid comprises a nonpolar boundary such that fluids exposed to the nonpolar boundary bead and form droplets having a dimension rendering them incapable of passing through one or more vent paths.

What is claimed is: 
     
         1 . A vented transfer lid for coupling engagement with an open threaded end of a container, the vented transfer lid comprising:
 a generally circular top panel comprising a transfer port extending from a generally central position on the top panel outwardly in a first or distal direction;   an attachment collar extending in a second or proximal direction from the top panel, an interior circumferential face of the attachment collar comprising threads for releasable engagement with corresponding exterior threads of the open threaded end of the container; and   an inner collar projecting from the top panel of the transfer lid in the second or proximal direction, the inner collar being generally concentric with and spaced a distance inwardly from the attachment collar, and comprising an outer circumferential surface having a texturized EDM surface finish.   
     
     
         2 . The vented transfer lid of  claim 1 , wherein the open threaded end of the container comprises an inner surface configured for interengagement with the texturized EDM surface finish of the outer circumferential surface. 
     
     
         3 . The vented transfer lid of  claim 2 , wherein the inner surface of the open threaded end is substantially smooth. 
     
     
         4 . The vented transfer lid of  claim 2 , wherein the inner surface of the open threaded end comprises a texturized EDM surface finish. 
     
     
         5 . The vented transfer lid of  claim 1 , wherein the EDM surface finish generally comprises a VDI range of between about 24-42. 
     
     
         6 . A transfer lid for coupling engagement with an open threaded end of a container, the transfer lid comprising:
 a generally circular top panel comprising a transfer port extending from a generally central position on the top panel outwardly in a first or distal direction; and   an attachment collar extending in a second or proximal direction from the top panel, an interior circumferential face of the attachment collar comprising threads for releasable engagement with corresponding exterior threads of the open threaded end of the container,   wherein at least a portion of an interior surface of the top panel comprises a texturized surface finish, and wherein the open threaded end of the container removably couples to the attachment collar such that at least one vent path is provided between the texturized surface finish of the interior surface of the top panel and the open threaded end of the container.   
     
     
         7 . The transfer lid of  claim 6 , wherein at least a portion of the interior surface of the top panel comprises an outer layer exhibiting oleophobic or hydrophobic characteristics. 
     
     
         8 . The transfer lid of  claim 6 , wherein an oleophobic or hydrophobic coating is applied to at least a portion of the interior surface of the top panel. 
     
     
         9 . The transfer lid of  claim 7 , wherein an oleophobic or hydrophobic substance is impregnated within at least a portion of the transfer lid. 
     
     
         10 . The transfer lid of  claim 6 , wherein the transfer port is configured for compatible engagement with a coupling of a syringe such that fluids can be transferred between the container and the syringe. 
     
     
         11 . The transfer lid of  claim 10 , wherein the transfer port comprises a male ISO 80369-3 formatted coupling and the coupling of the syringe comprises a female ISO 80369-3 formatted coupling. 
     
     
         12 . The transfer lid of  claim 11 , wherein the female ISO 80369-3 formatted coupling comprises a lumen extension tip. 
     
     
         13 . The transfer lid of  claim 6 , further comprising a collar surrounding the transfer port, the collar comprising at least one thread formed on an internal portion thereof. 
     
     
         14 . A transfer lid for coupling engagement with an open threaded end of a container, the transfer lid comprising:
 a top panel comprising a transfer port extending from a generally central position on the top panel outwardly in a first or distal direction, the transfer port configured for compatible engagement with a coupling of a syringe; and   an attachment collar extending in a second or proximal direction from the top panel, an interior circumferential face of the attachment collar comprising threads for releasable engagement with corresponding exterior threads of the open threaded end of the container,   wherein at least a portion of the transfer port comprises a texturized surface finish, and wherein engagement of the coupling of the syringe with the transfer port defines an engagement interface comprising at least one vent path.   
     
     
         15 . The transfer lid of  claim 14 , wherein the transfer port comprises a female enteral-only coupling and the coupling of the syringe comprises a male enteral-only coupling. 
     
     
         16 . The transfer lid of  claim 14 , wherein the transfer port comprises a male ISO 80369-3 formatted coupling and the coupling of the syringe comprises a female ISO 80369-3 formatted coupling. 
     
     
         17 . The transfer lid of  claim 14 , further comprising a texturized surface finish applied to at least a portion of an inner surface of the top panel.
