Abstract (en)
[origin: EP2883809A1] A cork stopper (1) coated with a resin layer having a columnar cork stopper body (2) formed by a compression molding of a cork granule with a binder resin, and a resin coating layer (3) covering an outer circumferential surface of the cork stopper (1) from an end side to another end of the cork stopper body (2) along an axial direction. The cork stopper body (2) and the resin coating layer (3) constitute a core portion (4), and the core portion (4), when being pressed in a hollow tubular portion with a tightening allowance of 1.5 mm, experiencing a compression stress of 100 N to 300 N in case of a moisture content ratio of the core portion (4) being 6 weight percent and experiencing a compression stress smaller by 100 N to 150 N than that in case of a moisture content ratio of the core portion (4) being 2 weight percent.
