Pouring devices can be found, for example, in U.S. Pat. No. 1,428,297 issued to Stephen Price on Sep. 5, 1922 in which there is disclosed a housing containing a discharge spout and a vent pipe in which the vent pipe has one end outside of the spout and one end within the container.
Another similar device can be found in Ward, that issued on May 28, 1968 wherein there is disclosed a liquid filtering device that can be surmounted on the top of bottles.
Chiu, in U.S. Patent publication 2014/0144329 on May 29, 2014 discloses a bottle-top wine decanter which has as its components, a wine-pouring tube that is filled with alkaline filter media, a breathing tube, a cap holding the wine-pouring tube, a stopper, and a magnetizer for activating wine to make the wine easy to drink.
None of these references deal with a pour spout that contains an adapter that operates as a reed valve.
Thus, what is disclosed and claimed herein is a filtration pouring spout for bottled liquids. The pouring spout comprises an elongated hollow housing coaxially surrounding a vertical axis, wherein the elongated hollow housing has a top end and a bottom end. Each end is open. The elongated hollow housing has two side-by-side open cavities, a first cavity being larger in opening than a second cavity.
There is a filter insert, the filter insert comprises an elongated hollow tube having the same length as the housing and an overall configuration to fit inside the first cavity. The filter insert has a bottom cap that is comprised of two through openings, a first through opening the same size as the first cavity and a second through opening smaller than the first through opening.
There is an adapter. The adapter is insertable in the top of the elongated hollow housing, and the adapter has two through openings, a large adapter through opening the same size as the first through opening and a smaller adapter through opening the same size as the second through opening. The smaller adapter through opening is covered with a diaphragm that acts as a reed valve.
There is a top nozzle, the top nozzle fits onto the adapter such that a side through opening in said nozzle aligns with the smaller adapter through opening. The top nozzle has a top nozzle through opening larger than the side through opening.
In a second embodiment, there is a filtration pouring spout for bottled liquids wherein the housing has a stopper encircling it that is adaptable to a top opening in a bottle.
