PEN NEEDLE ASSEMBLY OUTER COVER HAVING A BREAKAWAY FLANGE

摘要

An outer needle cover for a pen needle assembly is provided with a breakaway flange. Prior to use, the flange is connected to a body of the outer cover. The flange has a reduced cross sectional thickness portion that facilitates separation of the flange from the outer cover, thereby reducing the outer diameter of the outer cover. The reduced outer diameter of the outer cover allows the outer cover to be received by a pen cap of an existing injector device.
