摘要
PROBLEM TO BE SOLVED: To heighten a seal effect with the aid of a stopper when a bottle is sealed, make a content liquid in the bottle easier to drink after unsealing the bottle, and reduce a manufacturing cost by reducing inaccuracy of each of a bore diameter of the interior of a cap and a diameter of the stopper. ;SOLUTION: A cap comprises an outer cylinder 1 whose inner face is brought into contact with an outer face of a bottle mouth 6 when the bottle is sealed, an inner cylinder 2 which is brought into close contact with an inner face of the bottle mouth 6 at the same time, and a holding cylinder 4 which is spaced via a cavity 3 for absorbing stress from the inner cylinder 2 and is brought into contact with a stopper C, these cylinders being formed of a synthetic resin into one body. A plurality of ring- shaped contact protrusions 9 are provided on an inner face of the holding cylinder 4. On the other hand, the stopper C made of a synthetic resin, whose total specific gravity is made smaller than one so that the stopper C floats, is formed into a non- spherical shape having a cylindrical face 14 at a part of a sphere, so that a content liquid can be drunk up through a gap between the stopper and an opening of the cap holding cylinder 4 even under the condition where the stopper has returned to a mouthpiece of the bottle again after unsealing the bottle. Further, the stopper has a recess 12 formed therein.;COPYRIGHT: (C)1997,JPO
