Patent ID: 8196785

Claim:
A container for containing and dispensing liquids, comprising: a flask for containing a liquid, the flask comprising a bottom wall, a side wall joined to the bottom wall and extending upwardly therefrom, and a spout at a top end of the flask, the spout defining an access opening through which liquid may be dispensed, the side wall extending about a vertical axis of the flask so as to encompass a main internal space of the flask for holding liquid; the flask further including an air vent that comprises: a removable strip-shaped body having an internal face that defines a longitudinal groove therein; a channel defined in an external surface of the side wall of the flask, the channel extending longitudinally along the flask and being configured to receive the removable strip-shaped body with the internal face of the strip-shaped body facing toward the main internal space of the flask such that an air duct is formed between the longitudinal groove and an external surface within the channel, the air duct defining an air inlet for admitting air external to the flask into the air duct; and a trespassing hole extending through the side wall of the flask in the region of the channel, the trespassing hole communicating with the main internal space of the flask and with the air duct, whereby the trespassing hole and the air duct form the air vent; the container being configured such that when the flask is placed in a tilted position, air external to the flask passes through the air inlet into the air duct and through the trespassing hole into the main internal space of the flask before any liquid is discharged through the access opening of the spout, such that no vacuum is created in the main internal space of the flask.
