<p>A pourer has radial sealing flanges 2 through which a conduit 5 and air vent 10 pass; a chamber 15 in the air vent has an annular valve seat 17 against which the moving component 14 of the valve seals. Ideally the moving component is a ball and fall under gravity against the seat as the pourer is inverted. There are preferably multiple apertures in the chamber allowing ingress of liquid. The conduit and vent can be entirely contained between the sealing flanges or extend out from either end. There may be a baffle at the end of the conduit. The pourer could be used with a bottle 13.</p> |
