Coffee filter
A filter assembly that includes a receptacle, filter, and filter holder. The receptacle has an inside surface defining an open-ended first through-channel. The filter is positioned inside the first through-channel and configured to produce a filtered liquid by filtering particulates each larger than a predetermined size from a liquid. The filtered liquid exits the filter through an outlet opening of the filter. The filter holder removably couples the filter to the receptacle. A holding area configured to receive the liquid is defined in the first through-channel above the filter holder and between the filter and the inside surface of the receptacle. The filter holder includes an open-ended second through-channel in fluid communication with the outlet opening and configured to receive the filtered liquid from the outlet opening. The second through-channel is configured to be in fluid communication with an interior of a container and to provide the filtered liquid thereto.
1 . A beverage filtration apparatus comprising:
a receptacle at least partially defining a through-channel,
wherein the through-channel comprises an upper opening, the upper opening being configured to receive a liquid and beverage particulates, and
wherein the receptacle comprises a lower portion, an upper portion, and a middle tapered portion therebetween;
a filter member positioned inside the through-channel, the filter member including a plurality of through-holes in a vertical sidewall of the filter member, the plurality of through-holes being configured to allow the liquid to pass therethrough and configured to prevent the beverage particulates from passing therethrough;
a filter holder member configured to receive the liquid passing through the filter member,
wherein an upper portion of the filter holder member is removably coupled to the filter member at least partially inside the tapered portion of the receptacle,
wherein an intermediate portion of the filter holder member is removably coupled to the lower portion of the receptacle, wherein the intermediate portion of the filter holder member comprises outside threads and the lower portion of the receptacle comprises inside threads, and wherein the outside threads are configured to engage the inside threads to removably couple the filter holder member to the lower portion of the receptacle, and
wherein a holding area is defined in the through-channel above the filter holder member and between an outer vertical surface of the filter member and an interior surface of the receptacle, the holding area being configured to hold at least the beverage particulates; and
an internal tapered sidewall of the filter holder member, the internal tapered sidewall extending from the upper portion of the filter holder member through the intermediate portion of the filter holder member, the internal tapered sidewall defining a through-passage configured such that filtered liquid passes through the through-passage.
2 . The beverage filtration apparatus of claim 1 , further comprising:
an open lower end of the filter member, the open lower end positioned at least partially inside a tapered portion of the receptacle; and
a closed upper end of the filter member opposite the open lower end, the closed upper end positioned at least partially inside the upper portion of the receptacle, wherein the filter member extends from the open lower end to the closed upper end.
3 . The beverage filtration apparatus of claim 2 , wherein the filter member has a hollow interior defined by the vertical sidewall, the closed upper end, and the open lower end.
4 . The beverage filtration apparatus of claim 1 , wherein the filter member is cylindrically shaped.
5 . The beverage filtration apparatus of claim 1 , further comprising:
a lower end of the filter member; and
one or more bracket members of the filter holder member, wherein each of the one or more bracket members are removably connected to the lower end of the filter member, thereby forming a liquid seal between the filter member and the filter holder member.
6 . The beverage filtration apparatus of claim 1 , wherein an outer surface of the filter holder member forms a seal with an inner surface of the lower portion of the receptacle when the filter holder member is removably coupled to the lower portion of the receptacle.
7 . The beverage filtration apparatus of claim 1 , further comprising a flange having a central sidewall portion disposed about the lower portion of the receptacle, the flange being supported by the filter holder member, wherein at least a portion of a bottom surface of the flange is configured to sit on a container.
8 . The beverage filtration apparatus of claim 7 , wherein the flange is configured to support the weight of at least the receptacle, the filter holder member, and the filter member.
9 . An apparatus comprising:
a receptacle at least partially defining a through-channel,
wherein the receptacle comprises a lower portion, an upper portion, and a middle tapered portion therebetween;
a filter member positioned inside the through-channel, the filter member including a plurality of through-holes in a vertical sidewall of the filter member;
a filter holder member,
wherein an upper portion of the filter holder member is removably coupled to the filter member at least partially inside the tapered portion of the receptacle,
wherein an intermediate portion of the filter holder member is removably coupled to the lower portion of the receptacle, wherein the intermediate portion of the filter holder member comprises outside threads and the lower portion of the receptacle comprises inside threads, and wherein the outside threads are configured to engage the inside threads to removably couple the filter holder member to the lower portion of the receptacle, and
wherein a holding area is defined in the through-channel above the filter holder member and between an outer surface of the vertical sidewall of the filter member and an interior surface of the receptacle; and
an internal tapered sidewall of the filter holder member, the internal tapered sidewall extending from the upper portion of the filter holder member through the intermediate portion of the filter holder member, the internal tapered sidewall defining a through-passage configured such that filtered liquid passes through the through-passage.
