Total Claims: 18
Claim 1
Independent Claim
209 words
In a corn popper, a base adapted to be rested on a supporting surface; a heating element within said base; means associated with said base providing a receptacle for corn to be popped; a cover fitting over said receptacle; manipulating handle means by which said base and cover may be inverted; and means providing self buttering of said corn once popped, said self buttering means comprising a base-carried butter cup mounted above said receptacle and within said cover, said butter cup constructed and arranged for receiving a quantity of solid butter suitable when melted for buttering said corn when popped, removable closure means for said butter cup, said removable closure means manipulable to open said butter cup to deposit therein of said buttering quantity of solid butter, said butter cup constructed and arranged also for melting of said solid butter quantity under corn popper heating time and temperature causing said kernels to be popped, and means aperturing said self buttering means above the level of said melted butter in said cup whereby, when and only when said base is inverted and said popped corn thereby deposited in said cover, said melted butter is enabled and caused to flow out of said cup and drip onto said cover-deposited pop corn.
