A coffee-style brewer that pours and collects from opposite sides
A countertop beverage extractor that holds roasted plant granules (coffee, barley, toasted tea), pours hot water from one side of the granule bed, and collects the extract from the same side while a detachable restraining member seals the bed. It is intended to reduce excessive bitterness by controlling flow through specific layers of the granules while preserving desirable flavors and body. Typical users would be coffee-machine makers, cafes or R&D teams testing brew profiles.
(57) What the patent covered
The main independent claim covered an apparatus with: a granule-containing chamber for roasted plant granules; a first pouring device that delivers extraction solvent into the chamber from a first direction; a collecting device that collects extract liquid at the first side of the granule layers corresponding to that pouring direction; and a detachable restraining member inside the chamber that contacts or is close to both the first side and the opposite side of the granule layers and places the granules in a substantially sealed state.
Distinguishing feature: A removable restraining member that seals the granule bed and combined flow-path geometry that feeds and collects solvent from the same side to bias extraction away from other layers.
Novelty 3/5. An improvement on familiar percolation brewers and pour-over devices: controlled directional flow and a sealing insert to alter which layer contributes most to the extract was not common, but the basic elements (pouring spouts, filter beds, collection ports) were already standard.
Manufacturing
Injection-molded plastic body, stamped or machined metal pour/collect fittings, molded silicone or rubber restraint, assembly with fitted seals and filtration element insertion.
Materials: Food-grade plastic (PP or ABS) for body, stainless steel or brass for pour/collect fittings, porous filter media (paper, metal mesh, or sintered plastic), silicone or rubber for the detachable restraining member gasket.
Manufacturability 4/5. Requires several molded or stamped parts plus a molded rubber gasket and straightforward assembly; tolerances for sealing faces matter but no high-precision machining or electronics are needed.
Market demand

Buyers: Cafes, specialty coffee equipment makers, lab/R&D staff testing brews.
Before manufacturing
No related continuation or divisional patents in force were found. Design patents, trademarks and unrelated patents may still cover the product.
Practical effect depends on internal flow geometry and fit of the restraining member; crowded market for brewers and performance claims depend on brew variables rather than only hardware.
