Abstract

A package for a container including a tubular barrel having open distal and proximal ends, the proximal end being sized and shaped to receive a plunger, and the distal end being sized and shaped to receive an injection needle, the package including a plunger rod for the container, a part of the plunger rod being shaped complementarily to at least a part of the external shape of the tubular barrel, and a tray connectable to the plunger rod, the tray and the plunger rod forming the package when they are connected to each other.

First claim

The invention claimed is:

1. A package for a container comprising:
a tubular barrel having open distal and proximal ends, the proximal end being sized and shaped to receive a plunger, and the distal end configured to receive an injection needle, said package comprising:
i) a plunger rod for said container, a part of said plunger rod being shaped complementarily to at least a part of the external shape of said tubular barrel, and
ii) a tray connectable to said plunger rod, said tray and said plunger rod forming said package when they are connected to each other, wherein said package at least partially encloses said tubular barrel, wherein the part of the plunger rod comprising a first longitudinal portion and a second longitudinal portion, wherein at least a first member of a lock is located on said first longitudinal portion and a second member of a lock is located on said second longitudinal portion, and wherein said first and second members are engageable with each other when said plunger rod is not connected to the tray.

2. A package according to claim 1 , wherein said plunger rod and said tray are connected to each other by a releasable connecting member.

3. A package according to claim 2 , wherein at least part of said releasable connecting member is provided between said plunger rod and said tray.

4. A package according to claim 2 , wherein at least part of said releasable connecting member is provided on said plunger rod and on said tray.

5. A package according to claim 2 , wherein said releasable connecting member comprises a lock.

6. A package according to claim 2 , wherein at least part of said releasable connecting member is provided on one of said plunger rod and tray.

7. A package according to claim 3 , wherein said releasable connecting member comprises one removable tear-off line delimiting the outline of said plunger rod with respect to said tray.

8. A package according to claim 1 , wherein the first longitudinal portion and the second longitudinal portion are coupled to each other by a longitudinal living hinge.

9. A package according to claim 1 , wherein the part of the plunger rod that is shaped complementarily to at least a part of the external shape of the tubular barrel is a solid shaft showing at least one concave longitudinal face.

10. A package according to claim 1 , wherein the plunger rod includes a first end for attaching said plunger rod with the plunger intended to be received in said container.

11. A package according to claim 1 , wherein the plunger rod is attachable with the plunger at a distal end of one of said first longitudinal portion and said second longitudinal portion.

12. A package according to claim 9 , wherein the plunger rod is attachable with the plunger at a distal end of said solid shaft.

13. A package according to claim 1 , wherein a flange is provided at a proximal end of said plunger rod.

14. A package according to claim 1 , wherein said tray comprises an outer shape for stacking engagement with another said tray.

15. A package according to claim 5 , wherein the lock comprises a peg extending from the tray and a recess formed in the plunger rod, the recess sized to receive the peg, the peg removably connectable with the recess.

16. A package according to claim 5 , wherein the lock comprises a peg extending from the plunger rod and a recess formed in the tray, the recess sized to receive the peg, the peg removably connectable with the recess.

17. A package according to claim 1 , wherein the first member of the lock comprises a peg and the second member of the lock comprises a recess, the recess sized to receive the peg, the peg removably connectable with the recess.

18. A package according to claim 14 , wherein the outer shape of the tray includes a distal wall having a concave shape extending outwardly from the package and a proximal wall having an outer circular convex shape, the concave shape complementary to the outer circular convex shape of the proximal wall thereby allowing stacking engagement with another said tray.
