Abstract
An injection device includes a generally tubular outer body (10) and a medicament cartridge assembly carried within the outer body. The cartridge assembly includes a glass container (14), a charge of medicament (36) disposed within the glass container, a plunger member (28) rearwardly confining the medicament, and a seal (22) for sealing the forward portion of the glass container. A needle (34) has a rearward end disposed proximate the seal, with the seal and needle being movable with respect to one another. A rigid needle cover member (40) is normally maintained in an inoperative position and is movable relative to said body to a protective position wherein the needle cover member extends forwardly to cover the forward end of the needle.
