Abstract

A fluid transfer lid for removably coupling to pharmacy bottles or containers for withdrawing and/or delivering liquid medication or other fluid therefrom or thereto. In example forms, a syringe comprising a male or female connection tip couples with a transfer port of the lid, thereby allowing the transfer of fluids from the container and to the syringe.

First claim

What is claimed is:

1. A fluid transfer lid comprising:
a nipple comprising a length and extending longitudinally along a first axis from a surface and comprising a chamfer formed at an end thereof, the nipple comprising an outside diameter near the chamfer of between about 5.36 millimeters to about 5.46 millimeters, and an outside diameter near the surface of between about 5.59 millimeters to about 5.69 millimeters;
a lumen extending generally axially along the first axis through the nipple, the lumen comprising a diameter of between about 0.1 millimeters to about 2.95 millimeters; and
a cooperating connector having an outer housing surrounding the nipple, the outer housing being threaded on an internal portion thereof, the threads defining a root width between about 1.05-1.25 millimeters, a crest width between about 1.80-2.00 millimeters, and a pitch width between about 2.45-2.55 millimeters.

2. The fluid transfer lid of claim 1 , further comprising a tethered closure cap attached to the lid for removable engagement and closure of the nipple.

3. The fluid transfer lid of claim 1 , wherein the length of the nipple is between about 0.1 millimeters to about 1,000 millimeters.

4. The fluid transfer lid of claim 1 , wherein the length of the nipple is about 6.82 millimeters.

5. A fluid transfer lid for engagement with a syringe comprising an ISO 80369-3 formatted female coupling and a dosing control coupling, the fluid transfer lid comprising a generally circular top panel and a transfer port comprising a length extending longitudinally along a first axis from a generally central position on the circular top panel outwardly in a first direction, and an attachment collar extending in a second and generally opposite direction from the top panel whereby an internal circumferential face thereof comprises one or more threads for releasably engaging corresponding threads of a container, wherein the transfer port comprises a chamfer formed at an end thereof and defines a lumen extending generally axially along the first axis therethrough, wherein the transfer port comprises an outside diameter near the chamfer of between about 5.36 millimeters to about 5.46 millimeters, wherein the transfer port comprises an outside diameter near the circular top panel of between about 5.59 millimeters to about 5.69 millimeters, wherein the lumen comprises a diameter of between about 0.1 millimeters to about 2.95 millimeters, and wherein the length of the transfer port is between about 0.1 millimeters to about 1,000 millimeters, and whereby the dosing control coupling comprises a generally centrally-positioned low dose tip for being received within the lumen of the transfer port when the syringe is coupled to the transfer port.

6. A fluid transfer lid comprising:
a generally circular top panel;
a nipple comprising a length and extending longitudinally along a first axis from a generally central position of the circular top panel, the nipple comprising a chamfer formed at an end thereof and a lumen extending generally axially along the first axis therethrough; and
an attachment collar extending in a second direction from the circular top panel, an internal circumferential face thereof being threaded to releasably engage corresponding threads of a container, wherein the threads of the attachment collar define a root width between about 1.05-1.25 millimeters, a crest width between about 1.80-2.00 millimeters, and a pitch width between about 2.45-2.55 millimeters.

7. The fluid transfer lid of claim 6 , wherein the nipple comprises an outside diameter near the chamfer of between about 5.36 millimeters to about 5.46 millimeters.

8. The fluid transfer lid of claim 6 , wherein the nipple comprises an outside diameter near the circular top panel of between about 5.59 millimeters to about 5.69 millimeters.

9. The fluid transfer lid of claim 6 , wherein the lumen comprises a diameter of between about 0.1 millimeters to about 2.95 millimeters.

10. The fluid transfer lid of claim 6 , further comprising a tethered closure cap attached to the lid for removable engagement and closure of the nipple.

11. The fluid transfer lid of claim 6 , wherein the length of the nipple is between about 0.1 millimeters to about 1,000 millimeters.

12. The fluid transfer lid of claim 6 , wherein the length of the nipple is about 6.82 millimeters.

13. The fluid transfer lid of claim 6 , wherein the attachment collar comprises an exterior circumferential face, and whereby one or more closely-spaced indentations or gripping features may be formed on the exterior circumferential face to assist a user in installing and removing the transfer lid onto and from the container.

14. The fluid transfer lid of claim 13 , wherein the gripping features comprise generally closely-spaced elongate, ridge-like indentations formed along the exterior circumferential face.

15. The fluid transfer lid of claim 10 , further comprising indicia on at least a portion of the tethered closure cap.
