Patent ID: 8123086

Claim:
A pouring device for use with a bottle having a liquid therein, comprising: a cylindrical body formed of a flexible, elastic, resilient material and having a lower portion terminating at a first end, and an upper portion terminating at a second end, the lower portion having a length and adapted to be inserted into an opening of a bottle in sealing engagement with the bottle and the upper portion having a length, a height and a substantially circular interior cross-sectional shape and disposed adjacent the lower portion for extending above the opening of the bottle when the lower portion is inserted in sealing engagement with the bottle; a filter including a pour opening composed of a plurality of substantially uniformly disposed apertures, the pour opening extending across substantially an entire substantially circular cross section of the cylindrical body; an air passageway disposed adjacent to the internal periphery of said lower portion and extending longitudinally beyond the length of said lower portion in a direction away from said upper portion along the internal periphery of said cylindrical body, a portion of the air passageway overlapping the whole length of said filter in the longitudinal direction, the air passageway and the filter being comprised in a unitary body; and a visual indicator disposed on an outer surface of said upper portion for identifying the relative angular location of said air passageway with respect to said visual indicator; the cylindrical body extending above and surrounding the uniformly disposed apertures and the air passageway such that the shape of the upper portion is adapted to permit sealing the liquid in the bottle from the atmosphere by a cylindrical longitudinal extent of a cap insertable into the interior of the upper portion to close both the apertures of the filter and the air passageway to the atmosphere.
