ABSTRACT OF THE DISCLOSURE A hypodermic syringe has a collapsible reservoir made at least in part of a synthetic thermoplastics material, and a hypodermic needle in fluid communication with the reservoir. The reservoir has two walls which are angularly movable towards and away from each other about a hinge-point, the walls being connected to each other and to a third collapsible wall via folding lines defining hinges. The material of the reservoir is so treated, at least along the folding lines, that the two walls are biased towards each other.
