Claim 1
Independent Claim
294 words
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.

Claim 6
Dependent Claim
59 words
The decanter of claim 3 in which the means for connecting one end of the spring to the top wall takes the form of a pair of posts depending from the underface of the top wall, and a crosspiece on the end of the spring having end portions formed with apertures which receive reduced end portions of the posts.
Claim 7
Dependent Claim
38 words
The decanter of claim 5 in which each of the reduced end portions of the posts have angularly spaced ribs projecting therefrom and biting into the material of the crosspiece at the aperture in which it is received.

The decanter of claim 7 in which the receptacle comprises an outer layer of lexan and a lining of styrene, with the lining being enlarged at the open top to provide a ring that is flush with the outer layer, and the cover comprises an annulus of styrene having upper and lower ends, a shoulder outstanding from said annulus between said upper and lower ends, and a skirt of lexan secured to and depending from said shoulder in spaced relation to the lower portion of said annulus to provide an annular groove, and a packing member in said groove.
Claim 10
Dependent Claim
58 words
The decanter of claim 8 in which the ring at the top of the receptacle is formed with a plurality of angularly spaced cam ribs on its outer surface and the skirt has a plurality of inwardly projecting cam ribs angularly spaced apart whereby they cooperate with the cam ribs on the receptacle to provide a bayonet joint.
Claim 11
Dependent Claim
39 words
