Abstract
An automatic injecting device including an elongated housing assembly, a stressed spring assembly mounted within the housing assembly so as to be released in response to a predetermined manual acutation procedure, and a medicament cartridge assembly mounted within the housing assembly in cooperating relation with the stressed spring assembly comprising a hypodermic needle and a medicament container housing forward and rearward individual dosages of different relatively incompatible liquid medicaments mounted therein and separated by a deformable stopper. The medicament container is formed of glass and includes a cylindrical wall open at its rearward end and having an exteriorly flanged necked down forward end portion. A hub assembly connects the exteriorly flanged necked down forward end portion with the hypodermic needle. A separate fitment of molded plastic material is mounted within the interior of the cylindrical glass wall adjacent the necked down forward end portion thereof for radially inwardly deforming the stopper during operation and thereby providing an axial by-pass in the periphery thereof.
