Abstract
A syringe for parenteral injection of a semi-solid formulation. The syringe includes a hollow element forming a reservoir for the semi-solid product to be injected between a plunger and a needle hub urged in contact with the reservoir end. The plunger comes into direct contact with the hub when the dose contained in the reservoir-forming element has been injected. The element forming a reservoir and the needle are maintained mutually interlocked at the hub through a mount or case receiving the element forming a reservoir.
