Abstract: A bottom portion (6) of an aseptic filling bottle (1) includes a ground contact portion (10) that comes into contact with a mounting surface, a center portion (12) that progressively intrudes interior of the bottle as it extends radially inwards from the ground contact portion (10), and a dome portion (13) that is provided at a center of the center portion (12) to intrude the interior of the bottle further than the center portion (12). A dome portion side circumferential edge (12a) of the center portion (12) has an intrusion height (D1) into the bottle interior, which height is higher than a half (D2) the height from the ground contact portion (10) to a boundary between the body portion and the bottom portion (6).

Abstract: A cork stopper is coated by a resin coating layer, having a columnar cork stopper body constituted with a molded cork body, and a resin coating layer covering an outer surface of the cork stopper body. The resin coating layer has a resin adhesion layer directly adhered onto the outer surface of the cork stopper body, and a resin layer adhered onto the outer surface of the cork stopper body with the resin adhesion layer interposed therebetween, and the resin coating layer on a circumferential face of the cork stopper body has a layer thickness from 100 to 240 ?m.

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