发明名称 Dispensing beverage closure
摘要 An injection moldable closure includes a base member having a top and a substantially cylindrical side with internal threads thereon. The top of the base member includes a socket with an aperture at the bottom of the socket and a groove extending away from the socket. The closure includes a pour spout which is symmetrical about a longitudinal axis thereof. The pour spout includes a cylindrical stem, a ball attached at one end of the cylindrical stem and a passageway extending through the cylindrical stem and the ball along the longitudinal axis of the pour spout. The ball of the pour spout is received within the socket such that the pour spout can be moved between a closed position with the cylindrical stem received within the groove and an open position wherein the passageway is aligned with the aperture.
