Abstract

Claims (22)

1 . An enteral fluid container comprising:

a containment shell; an open upper end including:

container threads, and

a container sealing lip defining an outwardly extending rounded surface, a shoulder positioned between the container threads and the outwardly extending rounded surface, and an angled inner container surface radially inward of the outwardly extending rounded surface; and

a vented transfer lid coupled to the open upper end and including:

a circular top panel comprising a transfer port extending from a 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 lid threads for releasable engagement with the container threads; and

an inner collar projecting from the top panel of the transfer lid in the second or proximal direction, the inner collar being concentric with and spaced a distance inwardly from the attachment collar, and comprising an outer circumferential surface engaged with the angled inner container surface and having a texturized surface finish defining a VDI range of between about 24-42,

wherein the outer circumferential surface is configured to permit the venting of air into and out of the container at an engagement interface between the angled inner container surface and the outer circumferential surface.

2 . The enteral fluid container of claim 1 , wherein the transfer port is configured for compatible engagement with a coupling of a syringe,

wherein engagement of the coupling of the syringe with the transfer port defines an engagement interface comprising at least one vent path permitting the venting of air into and out of the container.

3 . The enteral fluid container of claim 2 , wherein the transfer port comprises a female enteral-only coupling configured to engage the coupling of the syringe comprising a male enteral-only coupling.

4 . The enteral fluid container of claim 2 , wherein the transfer port comprises a male ISO 80369-3 (as of Oct. 12, 2017) formatted coupling configured to engage the coupling of the syringe comprising a female ISO 80369-3 (as of Oct. 12, 2017) formatted coupling.

5 . The enteral fluid container of claim 1 , wherein at least a portion of the outer circumferential surface comprises an outer layer exhibiting oleophobic or hydrophobic characteristics.

6 . The enteral fluid container of claim 1 , wherein an oleophobic or hydrophobic coating is applied to at least a portion of the outer circumferential surface.

7 . The enteral fluid container of claim 1 , wherein an oleophobic or hydrophobic material is impregnated within at least a portion of the outer circumferential surface.

8 . The enteral fluid container of claim 1 , wherein the transfer port is configured for compatible engagement with a coupling of a syringe so that fluids can be transferred between the container and the syringe.

9 . The enteral fluid container of claim 1 , wherein the texturized surface finish is formed using electrical discharge machining (EDM).

10 . The enteral fluid container of claim 1 , wherein the inner collar defines a slit sized to permit gas to vent therethrough and inhibit one or more beads or droplets of fluid from passing therethrough.

11 . The enteral fluid container of claim 10 , wherein the slit defines a width of 0.05-0.90 millimeters.

12 . The enteral fluid container of claim 10 , wherein the slit defines a length of 1.50-5.20 millimeters.

13 . The enteral fluid container of claim 10 , wherein the slit exhibits oleophobic or hydrophobic characteristics.
