20090314166 | Device and Method for Cleaning a French or Coffee Press - A press cleaning device and method are described for removing coffee grinds from a French or coffee press. The device includes a stem having a handle and a circular disk-shaped declining plane ramp disposed at different ends. The circumference of the ramp is substantially the same as the inner circumference of the press. The ramp includes a radial cut running diametrically from the center of the ramp toward the outer circumference. The cut is fabricated to provide a lower or leading edge paralleling the horizontal floor of the press and trailing the leading edge an upward slanted ramp that follows like a circular inclined plane to an upper or ending edge. When rotated, the lower edge, which parallels the floor of the coffee press while slicing and shoveling, transfers the grinds from the bottom of the press up the ramp whereupon the grinds are stacked and can be removed. | 12-24-2009 |
