Abstract
A disposable syringe for administering liquid medicinal agents to live animal or human subjects is disclosed. The syringe comprises a hollow cylinder, filled with a medicinal agent, with which an injection needle is attached. The cylinder surrounds a piston that can be moved by means of a piston rod towards the injection needle. The piston is produced from a thermoplastically processable rubber mixture and is delimited in the direction of the medicinal agent by a peripheral sealing lip that contacts the hollow cylinder and that can be deflected in the radial direction.
