A pour spout has a spout section with an elongate tubular body defining a liquid flow channel. The body has a fluted or corrugated configuration rendering the body flexible or bendable. A dispensing orifice is disposed at a dispensing end of the pour spout and an attachment end is disposed at an end of the body opposite the dispensing end. The attachment end has a liquid inlet orifice. A vent section of the pour spot is joined to the attachment end of the body. The vent section includes an air vent that defines an air flow path, which directs air from outside of the pour spout along the air flow path toward a container interior while bypassing the liquid flow channel.
