Pen needle packaging

1. A disposable pen needle, comprising:

a hub having a needle situated thereon having a patient end and a non-patient end;

a removable patient end cap attached at the distal end of the hub;

a removable non-patient end cap attached at the proximal end of the hub; wherein greater force is required to detach the patient end cap than is required to detach the non-patient end cap.

2. The disposable pen needle according to claim 1 , further comprising

a single continuous seam between the patient end cap and the non-patient end cap forming a sterile enclosure around the needle.

3. The disposable pen needle according to claim 2 , wherein the continuous seam creates a tortuous path barrier forming a sterile enclosure around the needle.

4. The disposable pen needle according to claim 2 , wherein a label is disposed over the single continuous seam to preserve stability.

5. The disposable pen needle according to claim 1 , wherein the patient end and non-patient end caps are mated via a threaded connection, which creates as a tortuous path sterility barrier.

6. The disposable pen needle according to claim 1 , wherein the non-patient end cap and the patient end cap each form a separate sterile enclosure around the non-patient end needle and patient end needle, respectively, on opposite sides of the hub.

7. The disposable pen needle according to claim 1 , wherein the non-patient end cap and/or the patient end cap is attached to the hub by at least one means selected from heat staking, threaded connection, breakable plastic webs, interference fit, adhesive, and friction welding.

8. The disposable pen needle according to claim 1 , further comprising:

an interference fit between the hub and the non-patient end cap; and

mating protrusions on the inside of the patient end cap and the outside of the hub engaging the hub and resulting in increased force required to separate the hub from the patient end cover relative to the force required to separate the hub from the non-patient end cover.

9. The disposable pen needle according to claim 1 , further comprising tethers connecting the non-patient end cap and the patient end cap to the hub after the seam between the non-patient end cap and the patient end cap is broken and the respective caps are detached from one another.

10. The disposable pen needle according to claim 1 , comprising a threaded mating connection between the patient end cap and the non-patient end cap.

11. The disposable pen needle according to claim 1 , wherein the patient end cap and the non-patient end cap are configured to lock together to enclose the hub after use.

12. The disposable pen needle according to claim 11 , wherein the patient end cap and the non-patient end cap are configured to be permanently locked upon engagement.

13. The disposable pen needle according to claim 1 , wherein a tear drop label and an inner shield are not present.
