PROBLEM TO BE SOLVED: To provide a bottle body which is easy to recycle, which is likely to eject contents out of the bottle body even with a simple mouth structure and which reliably prevents the contents from leaking out of the bottle body when a cap is attached to the mouth. SOLUTION: A part of a periphery of an upper end of a side wall 5 of a mouth 3 of the bottle body is notched to form a gutter-like ejection part 6 rising outward at a predetermined angle with respect to the side wall 5. A cap 4 comprises a disk-like closure 10 of a larger diameter than an outer diameter of the mouth 3 of the bottle body, a cylindrical outer cylinder 11 extending downward from an outer peripheral rim of the closure 10 along an outer peripheral face of the side wall 5 of the mouth 3 and a cylindrical inner cylinder 12 extending from the closure 10 inside the outer cylinder 11 along an inner peripheral face of the side wall 5 of the mouth 3 which are integrally formed. The inner cylinder 12 is equipped with an inner peripheral pressure contact part 18 in pressure contact with an entire circumference on a side wall inner peripheral face of the side wall 5 of the mouth 3. |
