Title: Bottle stopper

Abstract: A hollow stopper for dispensing fluid from a bottle having a neck and a top lip is provided. The stopper comprises a top wall having a laterally extending, downwardly open, spout-like protrusion. The top wall has a continuous, annular, uninterrupted undersurface for sealing engagement with the top lip of a bottle. An annular skirt depends from the top wall inwardly of said undersurface. The skirt is adapted to fit within the neck of a bottle and to move axially with respect thereto between a sealing position in which said undersurface is in sealing engagement with the bottle lip and a plurality of dispensing positions in which said undersurface is spaced from the bottle lip. The skirt includes an axial pouring slot extending from the top wall undersurface along one side of the skirt in alignment with the spout-like protrusion. The skirt also has a continuous, substantially axial, air-admitting channel substantially diametrically opposite the pouring slot and extending from the top wall substantially the full length of the skirt.
