Abstract
The invention relates to a compact coffee press comprising plunger member, a soft, flexible diaphragm, and a receptacle member comprising an outlet, wherein the diaphragm is reversibly displaceable between a first position where the plunger member is elevated above the diaphragm, and a second position where the plunger member is depressed and the diaphragm is inverted, the plunger member fitting substantially within the diaphragm, and the diaphragm fitting substantially within the receptacle member. The invention further relates to a method of brewing and extracting coffee with the use of the compact coffee press.
Claims19
A compact coffee press device comprising:
- a) a substantially rigid frustoconical plunger member tapering towards a base;
- b) a soft, flexible diaphragm located below, and integrally formed with, connected or connectable to, the base of the plunger member, the diaphragm comprising frustoconical side walls, widening from a top portion of the diaphragm closest to the base of the plunger member and having a diameter substantially the same as the base of the plunger member, towards a base portion;
- and
- c) a substantially rigid, frustoconical receptacle member connected or connectable to the base portion of the diaphragm, the receptacle member tapering from the end connected or connectable to the base of the diaphragm to a base portion defining an aperture, the base portion sized to rest on or within, or be supported by a coffee receptacle,
- wherein the diaphragm is reversibly displaceable between a first position where the plunger member is elevated above the diaphragm, and a second position where the plunger member is depressed and the diaphragm is inverted, the plunger member fitting substantially within the inverted frustoconical side walls of the diaphragm, and the inverted diaphragm fitting substantially within the frustoconical receptacle member, and
- wherein the aperture of the base portion of the frustoconical receptacle comprises, connects or is releasably connectable to, or defines a filter portion that opens the aperture when released.
