Abstract
Abstract A pouring device for facilitating smooth liquid flow from a bottle by establishing a path for liquid flow from the bottle and a further path for the ingress of replacement air into the bottle. The device has a central tubular portion with an aperture at the inner end and an outwardly flared conical portion at the bottle opening. A flange at the bottle opening attaches the device to the bottle itself. Ports in the outwardly flared conical portion permit outward flow of liquid in an axial direction while permitting the ingress of air through the central portion of the device and hence into the bottle through the inner opening.

274 words
A device for a bottle comprising a central tubular portion having an inner end terminating in an end plate formed with an air vent and an open pouring end, the inner end being arranged to enter the neck of a bottle, and the pouring end being a cone portion having, at the end thereof closest to the said inner end, a small diameter substantially equal to the diameter of the said inner end and extending to a large diameter substantially equal to the inner diameter of the neck of the bottle, said central tubular portion presenting at the large diameter end a radially outwardly extending flange, the periphery of which is joined to a cylindrical portion extending to the side of the flange in the direction towards the small diameter end of the pouring portion, the end of the cylindrical portion remote from the flange being formed with an inwardly projecting annular bead, engageable with an annular groove in the neck of the bottle, tHe portion of the central tubular portion between the flange and said inner end presenting formed integral therewith an annular conical skirt projecting in a direction towards said inner end and projecting radially outward to an outer diameter which is less than the said large diameter of the cone portion of the pouring end, and the cone portion of the central tubular portion between the skirt and the flange being formed with ports, said ports being of sufficient length in the axial direction along the said cone portion such that each port has a projected area in the axial direction to permit flow through said ports in said axial direction.
