Abstract
A medicinal syringe includes a cylinder with a proximal and distal end, and an outlet. The syringe contains, or is adapted to receive, a medicine or a diagnostic agent, and includes a plug. The surfaces of plug which touch the inside wall of the cylinder are preferably made of polytetrafluoroethylene. The material for the cylinder inside wall directly adjoins the surfaces of the plug, which touch the inside wall of the cylinder. The plug has at least one sealing lip and the mass-resultant of the sealing lip forms an acute angle with the axis of the syringe in that distal direction.
