PURPOSE: To provide a pouring port with cap which can reduce cost without a need of an assembling machine and can also be mounted in a prescribed direction with respect to a container.

CONSTITUTION: This pouring port with cap is formed of a pouring port body 2 in which a flange part 22 for mounting on an inner surface of a through hole of a container is provided on a periphery at a lower part of a cylindrical peripheral wall 21 and which can form an opening by tearing a thin part formed in a bottom part of the peripheral wall 21 by means of a pull-ring 25, and a cap 3 connected to the pouring port body 2 through a hinge part 4 and opens and closes an upper surface of the pouring port body 2. In this pouring port, a side 22a to regulate direction is formed in the flange part 22. Compared to a prior art pouring port with cap which is formed of two or more members, a costdown can be achieved because an expensive assembling machine can be saved. In addition, as a direction regulation can be realized in feeding the pouring port 1, the pouring port 1 can be mounted by an automatic machine in a prescribed direction.
