FIELD: medicine.SUBSTANCE: syringe comprises a syringe cylinder, a distal end of which represents a syringe cone and has a portion projecting radially so that to form an edge extending circumferentially with the edge having a first bevel. A cap piece comprises a clamp portion having a distal edge with a second bevel, and restraining forces are transmitted through the clamp portion onto radially projecting syringe portion; the first and second bevels interact to form a surface contact. If observed circumferentially, the clamp portion of the cap piece is discontinuous thereby forming a bearing surface.EFFECT: by frictional connection and form closure, using the method enables generating a force keeping the cap piece on the syringe body adequate for the reliable operation of the syringe.11 cl, 13 dwg |
