ABSTRACT:
A disposable unitary coffee maker is disclosed which includes similarly shaped top and bottom portions having cooperating annular flanges secured together in fluid-tight relation with a pump element interposed therebetween. The pump element encloses a coffee charge through which purified water from the bottom portion passes when heated. A fuse element prevents flow of water through the coffee charge until the water reaches a predetermined temperature at which time the heated water flows through the coffee charge into the top portion for pouring through a spout opening defined by a pull tab, a handle being provided to facilitate handling.
