Abstract: An one-mouth container for storing liquid capable of preventing pulsating flow and controlling a discharging speed approximately at a constant independently of the amount of an internal liquid in the container when the internal liquid is discharged, in which a blow-molded portion (23) is formed on the container body side portion of a container mouth portion; a narrowed portion (24), a discharge port (31) and an air channel (11) extending from a side wall of the blow-molded portion (23) to a space at an upper part of the container body are formed by narrowing down the narrowed portion; the air channel has such a length that air supplied through the air channel (11) is released directly in the internal liquid; and both a discharge port (31) and an air port (25) are formed at the narrowed portion (24).
