ABSTRACT:
Hypodermic syringe consisting of a compressible reservoir of a material at least partly consisting of a thermoplastic synthetic material, which reservoir is coupled to a hypodermic needle and of which one wall is movable towards an opposite wall. The walls are movable with respect to each other and have a common hinge-point in the manner of a pointed bellows. The walls are coupled with each other and with a third collapsible wall via folding straight lines acting as hinges. The material of the reservoir is treated such at least on the spot of these folding lines, that it tries to move the mutually movable walls toward each other.
