A one-piece pourout fitment and a closure member, in combination with a liquid containing container, incorporating an improved sealing configuration. A pourout fitment is fabricated in one piece and includes a disc-shaped member having a central opening, a peripheral bottle neck engaging member, an axial, hollow, pouring tube defining the periphery of the central opening, and an axial hollow, vent tube, concentrically located with respect to the pouring tube and connected thereto by a plurality of ribs. The upper portion of the pouring tube is outwardly flared and terminates in a substantially vertical section. The closure member has an upper panel and a depending skirt with interior, bottle neck engaging threads molded therein. An annular sealing groove is defined by annular projections depending vertically downward from the closure upper panel. The inner wall of the sealing groove is tapered to match the flare of the upper portion of the pouring tube. The outer wall of the sealing groove is substantially vertical. In operation, the pourout fitment member is engaged on the neck of a bottle. The closure member is then engaged with threads on the bottle neck. When the closure member is fully engaged, the bottle contents are sealed due to the engagement of the flared portion of the pourout fitment with the tapered inner wall of the sealing groove and the vertical end portion of the flared portion of the pourout fitment with the substantially vertical outer wall of the sealing groove.
