Claims28
A one cup beverage brewer for brewing a beverage from a grind in a porous wall packet of a predetermined shape containing a quality of such grind to brew a one cup beverage and comprising:
- a brew device including a beverage container table for receiving a beverage container and an overhead mounting a feed head spaced there above for emitting brewing liquid;
- an tray holder mounted below the feed head;
- an upwardly opening tray carried from the holder and including a perforated distribution plate and upstanding side walls defining a compartment configured to receive the packet with one side facing upwardly;
- and
- a platen carried from the overhead, sized to be received in such compartment, formed with a pattern of dispersing openings arrayed there across for flow of liquid from such feed head to be dispersed over such one side of such packet, such platen further being biased downwardly.
The one cup beverage brewer of claim 5 for use with a packet formed with a rectangular selected configuration and wherein:
- the platen is formed with the openings arrayed a rectangular pattern.
A one cup coffee brewer comprising:
- a tower including a container table and an overhang spaced there above;
- a coffee packet formed by a porous envelope containing a sufficiently large charge of coffee grind to fill such envelope to a selected depth, and to brew one cup of coffee such grind being responsive to moisture to swell and increase such selected depth;
- a feed head mounted on the tower for applying water to such packet;
- a tray interposed between the feed head and configured with a compartment sized to support the lateral sides of such envelope against lateral outward expansion, the tray further including a perforated bottom wall;
- a platen resting on the packet and formed with disbursement openings for receipt and flow of water from the feed head to disperse water down through the interstices formed between such grind and through the perforations in such bottom wall;
- and
- a spring biasing the platen downwardly against such packet to maintain such platen pressed against such packet as water is flowed from feed head through the openings into the charge of coffee grind.
A one cup coffee brewer for brewing coffee grind contained in a packet with a porous envelope and comprising;
- a brew tower including a container table with an overhang disposed thereover;
- feed head means on the overhang;
- tray means interspersed between the feed head means and the table and including constraining means for constraining the packet from expanding horizontally;
- platen means for pressing downwardly on the packet when inserted in such tray means;
- and
- flow distribution means in the platen means and tray means for directing flow from such feed head to be distributed substantially evenly through the grind in the packet toward the table.
A one cup coffee brewer comprising:
- a tower including a container table and an overhang disposed thereover;
- a feed head mounted on the overhang;
- a tray interposed between the feed head and table for receipt of a packet of coffee grind;
- a platen for floatable receipt on the packet when received in the tray;
- and
- flow distribution means in the platen and tray for receiving fluid flow from the feed head to direct it in controlled flow distribution through the packet toward the table.
A method of brewing one cup of coffee at a time, including:
- selecting a packet of loosely packed coffee grind of a quantity selected to brew one cup of coffee;
- pressing the packet between first and second perforated plates;
- and
- supplying fluid against the first plate to flow such fluid in through the perforations in the first plate through the packet and out the perforations in the second plate.
