Abstract

A reservoir for a liquid medicament is described. The reservoir includes a first boundary portion and a second boundary portion forming a cavity to receive the medicament. The first boundary portion is substantially opaque and flexible. The second boundary portion is substantially transparent and rigid.

First claim

The invention claimed is:

1. A reservoir for a liquid medicament, the reservoir comprising:
a first boundary portion,
a second boundary portion, wherein the first boundary portion and the second boundary portion form a cavity to receive the medicament, and
at least one outlet port in fluid connection with the cavity and intersecting the first boundary portion, wherein the at least one outlet port comprises a tube port integrally formed with the first boundary portion,
wherein the first boundary portion is opaque and flexible, and
wherein the second boundary portion is transparent and rigid.

2. The reservoir according to claim 1 , wherein the first boundary portion is stretchable.

3. The reservoir according to claim 1 , wherein the second boundary portion comprises at least one inflexible material.

4. The reservoir according to claim 1 , wherein the first boundary portion is collapsible onto or into the second boundary portion.

5. The reservoir according to claim 1 , wherein the first boundary portion and the second boundary portion are impervious to gases and fluids.

6. The reservoir according to claim 1 , wherein the second boundary portion is dyed.

7. The reservoir according to claim 1 , wherein the second boundary portion comprises a glass or a rigid and transparent polymeric material.

8. The reservoir according to claim 1 , wherein the first boundary portion comprises at least one of an elastomeric material, a flexible thermoplastic material or a polymeric material.

9. The reservoir according to claim 1 , wherein the first boundary portion comprises a multilayer structure.

10. The reservoir according to claim 9 , wherein the first boundary portion comprises an opaque metal foil.

11. The reservoir according to claim 9 , wherein the first boundary portion is laminated or coated.

12. The reservoir according to claim 1 , wherein the cavity is at least partially filled with the liquid medicament.

13. A reservoir for a liquid medicament, the reservoir comprising:
a first boundary portion,
a second boundary portion forming a cavity to receive the medicament, and
at least one outlet port in fluid connection with the cavity and intersecting the first boundary portion, wherein the at least one outlet port comprises a tube port integrally formed with the first boundary portion,
wherein the first boundary portion is opaque and flexible, and
wherein the second boundary portion is transparent and rigid.

14. The reservoir according to claim 1 , wherein the at least one outlet port is integrated into the first boundary portion.

15. The reservoir according to claim 1 , wherein the at least one outlet port is equipped and provided with a connector comprising one of a latch, a screw or a bayonet thread.

16. The reservoir according to claim 1 , wherein the at least one outlet port is sealed with an elastic plug or seal penetrable by an injection needle.

17. The reservoir according to claim 1 , wherein the tube port protrudes outwardly from the first boundary portion.

18. The reservoir according to claim 1 , wherein the first boundary portion and the second boundary portion are mutually bonded along a circumferentially extending seam.

19. The reservoir according to claim 1 , wherein the tube port comprises a mechanically deformable or flexible material of which the first boundary portion is made of.

20. The reservoir according to claim 1 , wherein the tube port comprises a flexible tube.

21. The reservoir according to claim 1 , wherein the first boundary portion is planar-shaped before the medicament is extracted though the at least one outlet port.

22. The reservoir according to claim 13 , wherein the first boundary portion and the second boundary portion are mutually bonded along a circumferentially extending seam.

23. The reservoir according to claim 13 , wherein the tube port comprises a mechanically deformable or flexible material of which the first boundary portion is made of.

24. A reservoir for a liquid medicament, the reservoir comprising:
a first boundary portion,
a second boundary portion, wherein the first boundary portion and the second boundary portion form a cavity to receive the medicament, and
at least one outlet port in fluid connection with the cavity and intersecting the first boundary portion,
wherein the first boundary portion is opaque and flexible,
wherein the second boundary portion is transparent and rigid,
wherein the first boundary portion and the second boundary portion are mutually bonded along a circumferentially extending seam, and
wherein the outlet port is equipped and provided with a connector comprising one of a latch, a screw or a bayonet thread.

25. The reservoir according to claim 1 , wherein the first boundary portion and the second boundary portion define a closed volume that forms the cavity such that the medicament is configured to contact the first and second boundary portions.

26. The reservoir according to claim 1 , wherein the medicament is within the cavity, wherein the medicament includes at least one pharmaceutically active compound.

27. The reservoir according to claim 1 , wherein the first boundary portion is initially of a planar or flat shape and forms a lid of the second boundary portion, wherein the second boundary portion is cup-shaped.

28. The reservoir according to claim 1 , wherein the first boundary portion is configured to deform from a planar shape to a shape defined by an inside surface of the second boundary portion.

29. The reservoir according to claim 15 , wherein the connector is configured to attach the outlet port with one of an injection device or an infusion device.
