Abstract
An automatic injector having a glass container protecting sleeve of thin plastic material assembled in an operative position within the injector housing with respect to the glass medicament container when the stressed spring actuating assembly is in an unreleased condition so as to protect the glass container against fracture (1) due to handling impacts prior to release of the stressed spring assembly and (2) due to the force transmitted to the plunger following the release of the stressed assembly. The sleeve includes a cylindrical portion disposed in engagement with a cylindrical periphery of the glass container when the protective sleeve is in its operative position and an annular flange extending from the rear end of the cylindrical portion disposed in rearwardly adjacent relation to the rear end edge of the glass container when the protective sleeve is in its operative position.
