  • THIS INVENTION relates to beverage extraction.
  • the invention relates to a device for preparing a beverage extract, and to a method of preparing a beverage extract.
  • the Inventor believes that a simple to operate portable device enabling the brewing of a rich coffee from ground beans will be desirable. It would also be desirable if such a device is sufficiently versatile to allow extraction of beverages from other materials, e.g. tea leaves, coffee bags, coffee pods and the like.
  • the term "particulate" material is intended to include any solids material from which a beverage can be extracted.
  • a first aspect of the invention provides a device for preparing a beverage extract from a charge of particulate material, the device including: a foraminous body defining a cylindrical passage with a closed end; and a plunger displaceable along the passage, thereby to exert pressure on a charge of particulate material receivable in use between the plunger and the closed end of the passage.
  • the foraminous body may include a cylindrical wall in which apertures are defined.
  • the foraminous body may include an end wall defining the closed end of the passage.
  • the end wall may have apertures.
  • the plunger may have a solid liquid impermeable end face for exerting pressure on the charge of particulate material.
  • the foraminous body may be in the form of an apertured cage.
  • the device may then include a mesh receivable inside the cage to cover apertures of the cage and still allow displacement of the plunger along the passage.
  • the mesh may have openings which are smaller than the apertures of the cage.

  • the cage 102 includes a cylindrical wall 110 having a foraminous lower portion 112 and a liquid impermeable upper portion 114, and a liquid impermeable end wall 116, which defines the closed end 106, fast with the lower portion 112.
  • the cage 102 has an open or openable end 118 in the upper portion 114.
  • the upper portion 114 adjacent the open end 118 defines an internal screw-thread 120.
  • the device 100 includes a mesh 121 in the form of a circular cylindrical sleeve receivable inside the cage 102 to cover apertures of the lower portion 112 and still allow displacement of the plunger 108 along the passage 104.
  • the mesh 121 has openings that are much smaller than the apertures of the lower portion 112.
  • the plunger 108 includes an end member 122 defining a solid liquid impermeable end face 124, a shank 126 extending away from the end member 122, a plunger bush or nut 128 through which the shank 126 extends, the plunger bush 128 being fast with the shank 126, and a turning handle 130 at an opposite end of the shank 126.
  • the bush 128 defines an external screw-thread 132 that screwingly engages with the screw-thread 120.
  • the plunger 108 is thus configured screw-threadedly to advance along the passage 104 by the complementary action of the screw threads 120 and 132.
  • the plunger 108 is removable through the open end 118 by completely disengaging the complementary screw-threads 120 and 132, i.e. by screwing the plunger bush 128 out of the upper portion 114 through the open end 118.
  • the device 100 also includes a vessel 134 defining a cavity 136 in which the cage 102 is receivable.
  • the vessel 134 may be of glass, stainless steel or a synthetic plastics or polymeric material.
  • the vessel 134 includes a lid 138 defining a receiving formation 140 through which the cage 102 is receivable in the cavity 136, with a portion of the cage 102 protruding above the lid 138.
  • the vessel 134 defines a pouring outlet 142.
  • the vessel 134 also includes a handle 144 attachable by means of a clamp portion and screws or nuts and bolts to an upper end of the cage 102, and a base 146 removably attachable in bayonet fashion to the handle 144.
  • the plunger 108 is removed from the cage 102 to leave the open end 118 unobstructed. If desired, the mesh 121 is received in the cage 102 to cover the apertures of the cage 102.
  • a charge of particulate material (not shown) is loaded into the cage 102. Water at a suitable temperature is poured into the open end 118 and passes over the charge of particulate material as it flows out the foraminous lower portion 112 into the cavity 136. Sufficient water is poured in to fill the vessel 134 to a desired level with brew. The plunger 108 is then inserted into the passage 104 and the screw-threads 120 and 132 engaged.
  • the solid material is pressurised between the end face 124 and the closed end 106 by rotating the plunger 108 using the turning handle 130.
  • the plunger is thus screw-threadedly advanced by the complementary action of the screw-threads 120 and 132, thereby expressing residual liquid from the charge of particulate material through the apertures of the foraminous lower portion 112.
  • the devices 10, 100 may also be used to prepare extracts from other starting materials than coffee, e.g. tea leaves. Preferably, a major portion of the charge of particulate material should be larger than the apertures of the foraminous body 12 or the openings of the mesh 121. It must however be understood that the devices 10, 100 may also be used with charges of particulate material themselves contained in a porous sachet, e.g. a coffee bag or pod or a tea bag, in which event the size of the particulate material relative to the apertures of the foraminous body 12 or the openings of the mesh 121 is of lesser importance. As will be appreciated, the mesh 121 or a similar mesh may also be used with the device 10.
  • the devices 10, 100 provide a simple to use portable device allowing the brewing of a rich coffee and other beverages.
