Rubber plugs, which are to be used with medical containers or medical devices, are produced by forming a vulcanizable, mixed rubber compound, vulcanizing a resultant formed rubber compound, treating the rubber plug with steam of high temperature and high pressure, treating the rubber plugs in an aqueous solution which has been adjusted to be acidic, rinsing the rubber plugs with high-quality water, washing the rubber plugs with a shower of dust- and germ-free water, and drying the rubber plugs by at least one of far infrared radiation and high frequency heating. The process makes it possible to reduce the number of insoluble fine particles, which are attracted on a surface of each rubber plug, to an extremely low level and moreover, remove (or deactivate) pyrogen substances on and in the vicinity of the surface of the rubber plug. |
