An inner insert is removably positionable in the opening of the base, the inner insert having an outward facing annular protrusion configured for insertion in the annular channel of the base, and a spout with a channel formed therethrough. At least a portion of the spout has external threading. An outer cap is positionable over the inner insert and has an opening for receiving the spout. A screw cap includes internal threading configured for rotational engagement with the external threading of the spout, wherein rotation of screw cap compresses at least a portion of the base between the inner insert and the outer cap.
