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.

Dependent claims

In a decanter for liquids from which gas emanates, an open-top cylindrical receptacle, a cover detachably mounted on said receptacle at its open top with a sealing fit, said cover including a generally vertical side wall defining a passageway confined by the perimetric boundary of said side wall, said side wall traversed by a top wall to completely block passage through said passageway, said top wall having a drinking opening and a gas relief vent, and an improved operating unit controlling opening and closing of said drinking opening and said vent, said operating unit comprising:

(a) a bar positioned on the underside of said top wall and generally parallel thereto;
(b) a valve member for said drinking opening on one end of said bar;
(c) a pushbutton on the other end of said bar and received through said vent, said pushbutton being disposed at an angle relative to said bar which is slightly less than 90 degrees on the side adjacent to the end of the bar;
(d) an O-ring about said pushbutton and engageable with the underface of said top wall to close said vent;
(e) a leaf spring having one end secured to said bar at the end having the pushbutton;
and
(f) means for connecting the other end of said spring to the underface of said top wall;
said pushbutton being loosely positioned in said vent when said O-ring and said valve member for the drinking opening are in fully closed position;
whereby upon partial depression of the pushbutton the latter engages the side of said vent closest to the end of said bar to constitute said side a fulcrum about which the pushbutton swings on further depression of the pushbutton to move said O-ring and valve member into open positions.
