摘要： A cork stopper used for sealing a container opening and a production method for the cork stopper. The cork stopper comprises a cork stopper body having a molded cork body and a synthetic resin outer layer covering an outer circumference of the molded cork body, the synthetic resin outer layer being made of a synthetic material treated with a roughening process on its surface. The cork stopper body is set to a freely rotatable jig and is rotated together with a transcribing mold with a concave-convex surface by pressing the transcribing mold onto the outer circumference of the cork stopper body while rotating the transcribing mold, thereby transcribing the concave-convex onto the surface of the synthetic resin outer layer.

摘要： A method for processing a rubber surface and a sealing member treated with the method. In the first mode, a rubber surface is formed with a large number of small dimples in a regularly dotted pattern by irradiating laser beams from a laser irradiation device. In the second mode, a skin layer of the rubber surface is removed by irradiating laser beams from the laser irradiation device. In the third mode, the first mode and the third mode are combined. A sealing member comprises rubber including a seal lip part for elastically and slidably contacting a counterpart member, wherein a sliding contact surface of the seal lip part contacting the counterpart member is treated with one of the first, the second and the third modes of the method for processing a rubber surface.
