Claim Text:
1. An injection device with a luer fitting, the injection device comprising: a compressible syringe body comprising two flexible sheets defining a reservoir; a male luer fitting that is substantially cylindrical having a tapered outer surface, a base end and a luer tip at an end of said male luer fitting opposing said base end, said male luer fitting provided as a separate component from the syringe body, said base end connected to and sealed within said flexible sheets, said male luer fitting having a channel therethrough for conducting contents of the reservoir; a first connecting structure arranged on said tapered outer surface of the male luer fitting between said base end and said luer tip; a shield cap having a generally cylindrical shaped portion arranged on the male luer fitting at a first position relative to said male luer fitting prior to use of the injection device, said shield cap having a second connecting structure on an inner surface of its generally cylindrical shaped portion and interacting with said first connecting structure to prevent inadvertent movement of said shield cap relative to said male luer fitting when said shield cap is arranged at said first position; a first seal comprising a pierceable membrane sealing said channel at said luer tip and preventing leakage therethrough of content from said reservoir at least when the shield cap is at said first position; and a second seal between said shield cap and said male luer fitting sealing the tapered outer surface and the luer tip of said male luer fitting from outside contamination, said second seal formed by said first and second connecting structures when the shield cap is arranged at the first position, wherein said shield cap is movable relative to said male luer fitting to a second position from said first position, said first seal being pierced by movement of said shield cap from said first position to said second position, wherein said first and second connecting structures each comprise at least one circumferential rib or raised ring.
