A pouring spout fitment for a flexible container comprising: a hollow canoe portion having an outer surface and an inner surface defining a passage extending through the body, wherein the canoe is configured to be attached to an inner surface of the flexible container; a hollow rigid member at least partially disposed within the hollow canoe portion, the hollow rigid member comprising a top end having a discharge opening and a base end, the base end extending from the hollow canoe portion toward the flexible container; an extendible spout at least partially disposed in the hollow rigid member and connected to the hollow rigid member, the extendible spout comprising: a proximal end and a proximal opening, the proximal end connected to the base end of the hollow rigid member, a distal end and a distal opening, the distal end configured to extend from and retract at least partially into the hollow rigid member, and a discharge passage that extends from the proximal opening to the distal opening, wherein the extendible spout is configured to dispense a pourable material from the flexible container through the distal opening when the hollow canoe portion is attached to the inner surface of the flexible container; and a removable lid which is selectively positionable between a closed position, wherein the removable lid covers the discharge opening of the hollow rigid member and the distal opening of the extendible spout and an open position, wherein the removable lid allows a pourable material to pass through the discharge opening of the hollow rigid member and the distal opening of the extendible spout, wherein the removable lid further comprises: a first sealing flange which engages with the top end of the hollow rigid member to form a seal between the removable lid in the closed position and the hollow rigid member; and a second sealing flange which engages with the distal end of the extendible spout to form a seal between the removable lid in the closed position and the extendible spout. a hollow canoe portion having an outer surface and an inner surface defining a passage extending through the body, wherein the canoe is configured to be attached to an inner surface of the flexible container; a hollow rigid member at least partially disposed within the hollow canoe portion, the hollow rigid member comprising a top end having a discharge opening and a base end, the base end extending from the hollow canoe portion toward the flexible container; an extendible spout at least partially disposed in the hollow rigid member and connected to the hollow rigid member, the extendible spout comprising: a proximal end and a proximal opening, the proximal end connected to the base end of the hollow rigid member, a distal end and a distal opening, the distal end configured to extend from and retract at least partially into the hollow rigid member, and a discharge passage that extends from the proximal opening to the distal opening, wherein the extendible spout is configured to dispense a pourable material from the flexible container through the distal opening when the hollow canoe portion is attached to the inner surface of the flexible container; and a proximal end and a proximal opening, the proximal end connected to the base end of the hollow rigid member, a distal end and a distal opening, the distal end configured to extend from and retract at least partially into the hollow rigid member, and a discharge passage that extends from the proximal opening to the distal opening, wherein the extendible spout is configured to dispense a pourable material from the flexible container through the distal opening when the hollow canoe portion is attached to the inner surface of the flexible container; and a removable lid which is selectively positionable between a closed position, wherein the removable lid covers the discharge opening of the hollow rigid member and the distal opening of the extendible spout and an open position, wherein the removable lid allows a pourable material to pass through the discharge opening of the hollow rigid member and the distal opening of the extendible spout, wherein the removable lid further comprises: a first sealing flange which engages with the top end of the hollow rigid member to form a seal between the removable lid in the closed position and the hollow rigid member; and a second sealing flange which engages with the distal end of the extendible spout to form a seal between the removable lid in the closed position and the extendible spout. a first sealing flange which engages with the top end of the hollow rigid member to form a seal between the removable lid in the closed position and the hollow rigid member; and a second sealing flange which engages with the distal end of the extendible spout to form a seal between the removable lid in the closed position and the extendible spout.
