Brewing material holder with a top water spray
View Patent ↗A brewing material holder includes a closed bottom water dispersing member including ports providing streams of water from just under a holder lid bottom, for uniformly dispersing water into the brewing material in the holder. When water is injected into the holder, the flow of water is captured in the water dispersion member and directed up to the ports and sprayed horizontally or vertically into the brewing material, and sinks into brewing material contained in the brewing chamber. The water dispersion member may be attached to the holder lid or be part of the holder lid. A single centered port may be provided in the bottom of the dispensing member provides an additional spray and also helps drain the dispensing member after use.
1. A brewing material holder, comprising:
a base having an interior configured to hold brewing material, wherein the base is configured to be placed in a brewing chamber of a coffee maker and includes a recess configured to avoid a bottom puncture needle extending from a bottom of the brewing chamber; and
a removable lid attachable to and detachable from the base, wherein the lid includes:
a water inlet configured to receive an injection needle in fluid communication with a pressurized water supply of the coffee maker; and
a water-dispersing member including:
an injection needle chamber configured to provide space for the injection needle and limiting a release of water from the injection needle to directed sprays of water into the interior of the base;
a central vertical port in the injection needle chamber configured to provide a corresponding one of the directed sprays;
a disk-shaped circular chamber arranged in fluid communication with the injection needle chamber and disposed on a bottom surface of the lid, extending radially from the injection needle chamber above the interior of the base; and
a plurality of angularly spaced-apart second ports arranged in a floor of the circular chamber, spaced radially outward from the injection needle chamber about half the distance from an outer wall of the injection needle chamber to an outer rim of the circular chamber, and configured to provide a corresponding plurality of vertically downward directed sprays into the interior of the base.
