ABSTRACT:
A decanter for hot or cold liquids, comprising a cylindrical receptacle having an open top and a cover detachably mounted on the receptacle at its open top. The cover consists of an upper annulus and a skirt of larger diameter than the annulus and connected thereto by a shoulder. Portions of the skirt and the annulus are spaced apart to provide a groove which receives the upper edge portion of the receptacle with a sealing fit. A top wall is integral with the annulus and is tilted with respect to a plane normal to the axis of the receptacle. This top wall is formed with a drinking opening adjacent its periphery and a relief vent diametrically opposed to the drinking opening and also adjacent to the periphery of the top wall. Depending from the inner face of the top wall and between the drinking opening and vent are a pair of spaced posts. Mounted on the ends of the posts is an operating unit comprising a bar that is substantially parallel to the top wall, a valve on one end of the bar normally closing the drinking opening, a pushbutton on the other end of the bar received in said vent and of a size smaller than the vent, an O-ring on said pushbutton normally closing the vent, with the pushbutton being disposed at an angle slightly less than 90 degrees relative to the bar, and a leaf spring having one end integral with said bar at the underside of the end carrying the pushbutton, with its other end integrally connected to a crosspiece that is mounted on the ends of the posts.
