Abstract

A syringe nest is provided that includes a planar base and a plurality of nesting units extending from and interconnected by the base. Each nesting unit includes a hollow hexagonal body having a first open end and an opposing second open end.

First claim

We claim:

1. A syringe nest comprising:
a planar base; and
a plurality of nesting units extending from and interconnected by the planar base and having contiguous walls, each nesting unit comprising a hollow hexagonal body having a first open end and an opposing second open end, wherein the first open end of each hollow hexagonal body is distal from the planar base and the second open end is proximate the planar base.

2. The syringe nest of claim 1 , wherein the nesting units are arranged in a point-to-point orientation.

3. The syringe nest of claim 2 , further comprising a plurality of voids formed between the nesting units.

4. The syringe nest of claim 3 , wherein the voids are triangular shaped voids.

5. The syringe nest of claim 3 , further comprising an intermediate wall between first and second open ends of each of the voids.

6. The syringe nest of claim 1 , wherein the nesting units are arranged in a honeycomb pattern with no voids formed between adjacent nesting units.

7. The syringe nest of claim 1 , wherein the planar base is positioned at an intermediate position between the first and second open ends, such that a first portion of the hollow hexagonal body of each nesting unit extends distally from a first surface of the planar base and a second portion of the hollow hexagonal body of each nesting unit extends distally from a second surface of the planar base.

8. The syringe nest of claim 1 , wherein the planar base includes a plurality of stiffening members extending from at least one peripheral edge of the planar base toward the plurality of nesting units.

9. The syringe nest of claim 8 , wherein the plurality of stiffening members are formed on a first surface and a second surface of the planar base.

10. The syringe nest of claim 1 , further comprising at least one retention member below a plane of the first open end.

11. The syringe nest of claim 1 , wherein the hollow hexagonal body of each nesting unit includes a plurality of longitudinally extending slits separating the hollow hexagonal body into a plurality of spaced apart portions, at least one of the spaced apart portions being a flexing member.

12. The syringe nest of claim 1 , wherein the first open end of each nesting unit includes at least one cam and at least one associated recess, such that a syringe flange contacts and travels over the at least one cam and subsequently comes to rest in the at least one associated recess.

13. The syringe nest of claim 12 , wherein the first open end of each nesting unit includes a pair of opposing cams with the at least one recess being formed therebetween.

14. The syringe nest of claim 13 , wherein the pair of opposing cams are symmetrical.

15. The syringe nest of claim 13 , wherein the pair of opposing cams are asymmetrical inclined surfaces.

16. The syringe nest of claim 1 , further comprising at least one retention member comprising at least one of a flange, a shelf, a rib, and/or spaced bumps.

17. The syringe nest of claim 16 , wherein the at least one retention member comprises a radially inwardly extending longitudinal rib having a chamfered end.

18. The syringe nest of claim 1 , wherein the second open end of each hollow hexagonal body is in the same plane as the planar base.

19. The syringe nest of claim 1 , wherein the planar base surrounds the plurality of nesting units.

20. The syringe nest of claim 5 , wherein the intermediate walls are in a different plane than the planar base.

21. A syringe nest comprising:
a planar base; and
a plurality of nesting units extending from and interconnected by the base, each nesting unit comprising a hollow hexagonal body having a first open end and an opposing second open end and at least one retention member comprising a radially inwardly extending longitudinal rib having a chamfered end.
