Abstract

In one general aspect, a method for filling multiple containers with a pharmaceutical product is disclosed, which comprises decontaminating sealed nested materials in a transfer chamber, removing from the sealed nested materials one or both of a container nest holding the multiple containers and a closure nest holding multiple closures, transferring from the transfer chamber to a controlled environment enclosure the removed nest, aseptically filling the containers with the pharmaceutical product, and closing the containers with the multiple closures. The nests are configured to allow multiple closures and containers to be simultaneously aligned concentrically, and closed simultaneously. Spring-loaded retaining structures on the closure nest allow it to releasably retain multiple closures above the corresponding multiple containers. In some embodiments the spring-loaded features are monolithically integrated with the closure nest. The product may be lyophilized in partially sealed containers while the sealing closures are releasably retained by the closure nest.

First claim

The invention claimed is:

1 . A closure nest for releasably retaining a plurality of pharmaceutical container closures wherein each closure comprises a stopper retained within a cylindrical cap having a radially extending exterior holding feature, the closure nest comprising:
a plurality of closure retaining structures arranged on a planar support structure to spatially correspond with a plurality of pharmaceutical containers in a container nest, wherein each closure retaining structure comprises closure engaging structures disposed annularly about a cylindrical axis of a corresponding closure and arranged for suspending the corresponding closure by a holding feature of a corresponding cap, wherein each of the closure engaging structures comprises a spring-loaded arm extending substantially orthogonally from the planar support structure and a triangular suspension ledge extending toward a cylindrical axis of the corresponding closure, wherein the triangular suspension ledges of the closure engaging structures corresponding to each of the plurality of closure retaining structures form an annular arrangement, wherein the planar support structure comprises a plurality of openings corresponding to the plurality of closure retaining structures and wherein each opening has a largest dimension smaller than an inner diameter of the annular arrangement of suspension ledges, and wherein each of the closure engaging structures comprises a stop structure extending substantially orthogonally from the planar support structure for engaging a portion of a top surface of the closure cap.

2 . The closure nest of claim 1 , wherein the closure retaining structures are arranged in a geometric pattern.

3 . The closure nest of claim 1 , wherein the closure retaining structures are arranged in a hexagonal close packed pattern.

4 . The closure nest of claim 1 , wherein the spring-loaded arm of each closure engaging structure is elastically deformable spring-loaded arm.

5 . The closure nest of claim 1 , wherein the spring-loaded arm of each closure engaging structure is an elastically flexible spring-loaded arm.

6 . The closure nest of claim 1 , wherein the spring-loaded arm of each closure engaging structure is polymeric.

7 . The closure nest of claim 1 , wherein the spring-loaded arm of each closure engaging structure is monolithically integrated with the planar support structure.

8 . The closure nest of claim 1 , wherein the stop structure of each of the at least one closure engaging structures is monolithically integrated with the planar support structure.

9 . The closure nest of claim 1 , wherein for each of the plurality of closure retaining structures every closure engaging structure of the closure retaining structure shares with all of the other of the closure engaging structures of the closure retaining structure a single stop structure annularly arranged about the cylindrical axis of the corresponding closure.

10 . The closure nest of claim 9 , wherein the stop structure comprises a plurality of point contacts.

11 . The closure nest of claim 1 , wherein the closure retaining structures comprise at least three closure engaging structures disposed annularly about the cylindrical axis of the corresponding closure.

12 . The closure nest of claim 1 , wherein all portions of each of the closure retaining structures are disposed to remain out of contact with the stopper of a corresponding closure when the corresponding closure is engaged by the closure engaging structure of each of the plurality of closure retaining structures.

13 . A closure nest for releasably retaining a plurality of pharmaceutical container closures wherein each closure comprises a stopper retained within a cylindrical cap having a radially extending exterior holding feature, the closure nest comprising:
a plurality of closure retaining structures arranged on a planar support structure to spatially correspond with a plurality of pharmaceutical containers in a container nest, wherein each closure retaining structure comprises closure engaging structures disposed annularly about a cylindrical axis of a corresponding closure and arranged for suspending the corresponding closure on a holding feature of a corresponding cap, wherein each of the closure engaging structures comprises a spring-loaded arm extending substantially orthogonally from the planar support structure and a suspension ledge extending toward a cylindrical axis of the corresponding closure, wherein the suspension ledges of the closure engaging structures corresponding to each of the plurality of closure retaining structures form an annular arrangement, wherein the planar support structure comprises a plurality of openings corresponding to the plurality of closure retaining structures and wherein each opening has a largest dimension smaller than an inner diameter of the annular arrangement of suspension ledges, and wherein each of the closure engaging structures comprises a stop structure extending substantially orthogonally from the planar support structure for engaging a portion of a top surface of the closure cap.
