SINGLE USE BEVERAGE FILTER BASKET WITH NON-WOVEN FILTER MEDIUM

摘要

A disposable single-use beverage filter basket filled with beverage grounds, and a beverage brewer having a cartridge for placement of the beverage filter basket. A permeable filter basket has a rigid frame having a bottom, a plurality of ribs, and a top rim that define side openings, and a non-woven filter medium that is bonded thermally to the material of the frame to cover the side openings. The non-woven filter medium is made of recyclable or compostable plastic or bio-polymer, and frame is made of the material of the non-woven filter medium. The permeable filter basket is filled with beverage grounds and enclosed with a film cover. The inlet probe of the brewer pierces the cover and admits a heated liquid into the beverage grounds, and creates a brewed beverage that flows through the filter material and exits an opening in a bottom portion of the cartridge.

主权项

1. A permeable filter basket for containing beverage grounds during brewing of a beverage in a beverage brewer by introduction of pressurized water therethrough, the permeable filter basket comprising:
a frame formed of a polymer material comprising:
a continuous top rim that defines a top opening of the frame;a bottom having a peripheral edge; anda plurality of ribs that extends from the top rim to the bottom, the plurality of ribs, top rim and bottom defining a plurality of side openings;wherein the bottom is closed to inhibit passage of water therethrough during brewing and is adapted to redirect pressurized water contacting the bottom toward the top opening so as to facilitate intermixing of pressurized water with beverage grounds prior to exiting the filter basket through the plurality of side openings; a liquid-permeable non-woven filter medium insert formed of a polymer material comprised of random, interconnected fibers, the fibers collectively forming inherently disordered inlet and outlet fluid passageways therethrough, the non-woven filter medium insert being separately formed from the frame, wherein the non-woven filter medium insert is sized such that the material of the frame is bonded to the fibers of the non-woven filter medium insert along locations where the non-woven filter medium insert contacts the frame, whereby the non-woven filter medium insert covers the plurality of side openings so as to define a beverage grounds receptacle area that is in communication with the top opening.
