Abstract
Abstract A coffee maker assembly constituted by a decanter for boiling water and a separate container for producing with some of this water a highly-concentrated coffee brew, the container having a cap permeable to liquid and gas. The container is seatable in an inverted position over the decanter whereby steam generated by boiling water penetrates the cap and functions to express the highly-concentrated brew from the container into the water to intermingle therewith to produce a brew of the desired concentration.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
206 words
A coffee maker assembly for rapidly producing a coffee brew of good quality, said assembly comprising: A. a decanter for boiling water, said decanter being formed by a bowl having a cylindrical neck provided with an outwardly-extending flange; and B. a container constituted by a cylindrical outer cup whose diameter substantially matches the diameter of the decanter neck and a cylindrical inner cup of smaller diameter coaxially supported within the outer cup, the region between the cups defining a steam jacket, said inner cup being provided with a removable cap which is permeable to liquid and gas but not to ground coffee, whereby when a charge of ground coffee is placed in the inner cup and some of the water boiled in said decanter is poured thereover, this produces a coffee brew in the inner cup, and when the inner cup is thereafter capped and the container inverted over the decanter with the rim of the outer cup resting on the flange, steam evolved in said decanter fills the steam jacket to heat the interior of the inner cup and also penetrates the inner cup through said cap to produce a head of steam over the coffee brew therein to express the brew into the decanter.
