Claims

[Scope of utility model registration request]

A cap for sealing the mouth of a glass bottle, consisting of a cap body having a contents spout that is press-fitted into the bottle mouth, and a cap that is removably attached to the top of the cap body. The stopper body includes an outer cylinder that fits around the outer periphery of the bottle mouth, an annular upper surface that is integrally formed on the inner periphery of the upper end of the outer cylinder and that holds the rim of the bottle mouth from above, and An inner cylinder is formed integrally on the inner periphery of the top surface and has upper and lower ends open to serve as a content spout. A synthetic resin molded product having a cuttable inner lid that partitions the bottle into an upper and lower part, and a convex part on the inner peripheral surface of the outer cylinder that fits into an annular recess formed on the outer periphery of the mouth edge of the bottle mouth part. A pair of inner and outer annular seal pieces that come into elastic contact with the inner and outer peripheries of the rim of the bottle mouth are protruded from the inner surface of the upper surface, and between the inner lid forming position of the inner cylinder and the lower end of the inner cylinder. The part bulges out to the outer circumference side all around,
A glass bottle spout characterized in that the bulging portion is an elastically deformable bottle spout contact portion that comes into elastic contact with the inner circumferential surface of the bottle spout.
