CA 2243408

A sealing rubber closure is provided for use with a syringe/container specified by ISO (the International Organization of Standardization) and having a Luer nozzle to be inserted into a Luer-nozzle-receiving part of the sealing rubber closure. The Luer-nozzle-receiving part is configured, on a side of an inner end portion thereof, in an untapered cylindrical form to assure tight-fitted insertion of a free end portion of the Luer nozzle and, on a side of a Luer-nozzle-receiving opening thereof, in a tapered, substantially cylindrical form to assure tight-fitted insertion of a basal end portion of the Luer nozzle. A plastic film is laminated on the sealing rubber closure at least in an area of the Luer-nozzle-receiving part, where a free end of the Luer nozzle is to be maintained in contact with the sealing rubber closure. The sealing rubber closure can exhibit both excellent liquid leakproofness and superb gas sealing performance. The sealing rubber closure can avoid any contact with a liquid medicine so that it does not give any adverse effects to a liquid medicine filled in the syringe/container.
