CA 2126800

A brewer for providing a single cup of coffee which comprises an outer cylindrical tubular member having an open top and a platform formed on the top. A slidable second cylindrical tubular member reciprocates within the first tubular member along the axis thereof and is provided with a gasket at the top thereof in sealing contact with the inner surface of the first tubular member. A permanent filter is provided at the top of the second cylindrical tubular member. A fixed piston head is located within the second cylindrical tubular member and is fixed relative to the first tubular member. A wiper is provided on the top platform of the first tubular member such that when the filter is in its uppermost position, the wiper can be activated to clean the coffee grounds from the filter. A pour spout is provided in the second cylindrical member which communicates with the fluid once the pour spout is above the level of the piston head. In operation, the filter moves downwardly towards the piston head such that air passes upwardly through the water and coffee grounds on the filter to agitate the mixture and then upwardly towards the top of the first tubular member such that a negative pressure is created between the filter and the piston head to draw the solution through the filter and eventually out by means of the spout in the wall of the second cylindrical tubular member.
