PROBLEM TO BE SOLVED: To provide a rectifying discharge one port container which does not require a special mold structure and a blow pin, can be manufactured under normal manufacturing conditions, and to investigate a structure of an intake mechanism without any trouble at the time when inner liquid is filled and a pump is inserted or the like. SOLUTION: A large diameter part 24 having a larger opening area than that of a container mouth part 21 is provided between the container mouth part 21 and a main body, and an intake mechanism part 26 is formed on the main body side of this large diameter part 24 by narrowing down a part of or the whole periphery of a peripheral wall. Furthermore, the intake mechanism part 26 which simultaneously has a discharge port 25 having a larger opening area and an intake port 31 having a smaller opening area is formed. The intake port has a slit shape, a round-hole shape or a pipe-like shape. In order to prevent the intake port 31 from becoming an obstacle when the inner liquid is filled or the like, the discharge port 25 is the same shape as the container mouth part 21 and formed coaxially. |
