Spiralating Cafetière

A Cafetière operates by means of direct pressure on the coffee granules + water mixture contained within a glass vessel. A plunger is pressed straight down unto the mixture, until it reaches the bottom of the glass, leaving a mostly particle free filtered coffee infusion in the upper chamber.

It's a simple but very effective way of making coffee, but in its present form there is no method of agitating the water/coffee to make the infusion process more efficient.

Spiralating Cafetière introduces a new element to the apparatus to enhance the entire process. This new element is a corkscrew thread on the plunger shaft, and a corresponding receiver on the normally circular hole through which the shaft travels.

This results in the plunger's filter head rotating as it is pressed down on the coffee/water mix. This rotation is delivered via a couple of ribs on the face of the filter face. The net result is that the coffee grain/water mix is agitated by the downward spiraling action, effectively releasing more coffee flavour. Clearly a better cup of coffee in the making.
