Abstract
Abstract A tap water filter (130), filter apparatus (150) and methods of use thereof are disclosed. The filter may be disposed between a one liter plastic beverage container (120) filled with tap water and an empty beverage container (122) to filter the tap water through filter media (164) into the previously empty container. The apparatus defines spouts (132, 134) that retain the containers in place. The filter also defines a buffer (140) that automatically prevents water overflow. The filter apparatus includes the filter and a storage container (152) which receives the filter and is supported, in turn, on a stand (154). Tap water may be filtered into the storage container and dispensed therefrom via a faucet (157) mounted in the container wall (158).

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
134 words
Water filter apparatus, comprising: a storage container defining an internal volume and having an opening communicating therewith; a filter enclosure defining a filter media cavity and entrance and exit apertures communicating with said cavity; an entrance spout projecting from said enclosure, said entrance spout defining (1) an internal passageway communicating with said entrance aperture and (2) an external surface dimensioned to be received in a neck opening of a dispensing container so as to abut the internal surface of said neck opening for supporting the dispensing container in an inverted orientation; said filter enclosure removably mounted in said storage container opening with said entrance and exit apertures opening, respectively, externally and internally of said storage container internal volume; and a selectably operable faucet mounted in said container for dispensing water from said internal volume.
Claim 2
Dependent Claim
134 words
Water filter apparatus, comprising: a storage container defining an internal volume and having an opening communicating therewith; a filter enclosure defining a filter media cavity and entrance and exit apertures communicating with said cavity; an entrance spout projecting from said enclosure, said entrance spout defining (1) an internal passageway communicating with said entrance aperture and (2) an external surface dimensioned to be received in a neck opening of a dispensing container so as to abut the internal surface of said neck opening for supporting the dispensing container in an inverted orientation; said filter enclosure removably mounted in said storage container opening with said entrance and exit apertures opening, respectively, externally and internally of said storage container internal volume; and a selectably operable faucet mounted in said container for dispensing water from said internal volume.
Claim 3
Dependent Claim
29 words
The filter apparatus of claim 1 wherein said filter defines about said entrance spout a peripheral buffer to pool water about said entrance spout for preventing water overflow therefrom.
Claim 4
Dependent Claim
33 words
The filter apparatus of claim 1 wherein said container defines a rim about said opening and said filter enclosure defines a lip to abut said rim for retaining said filter in said opening.
Claim 5
Dependent Claim
17 words
The filter apparatus of claim 1 further comprising a stand to receive said container for support thereof.
Claim 6
Independent Claim
133 words
A method enabling a user thereof to conveniently prepare and dispense filtered tap water thus eliminating the need to purchase bottled water and/or install permanent or semipermanent filter devices, the method comprising the steps of: providing a hollow storage container having a dispensing faucet mounted in a wall thereof wherein said container defines an opening through said wall; inserting a filter having an entrance spout and an exit spout into said opening with said entrance spout disposed external to said storage container and said exit spout disposed to drain into said storage container; mounting a tap water dispensing container on said entrance spout for discharging tap water into said entrance spout for filtering through said filter into said storage container; and pooling said tap water about said entrance spout, to prevent overflow therefrom.
Claim 7
Independent Claim
133 words

Claim 8
Dependent Claim
16 words
The method of claim 5 further comprising the step of dispensing filtered water from said faucet.
Claim 9
Independent Claim
101 words
A method of filtering tap water comprising the steps of: filling a dispensing container with tap water through a neck opening in said container; mounting said dispensing container in an inverted orientation on the entrance spout of a filter apparatus having entrance and exit spouts with the internal surface of said dispensing container neck opening abutting the external surface of said entrance spout; mounting said filter apparatus on a storage container to discharge water from said exit spout into said storage container; and pooling water from said dispensing container about said entrance spout to prevent water overflowing from said filter apparatus.
Claim 10
Independent Claim
101 words
A method of filtering tap water comprising the steps of: filling a dispensing container with tap water through a neck opening in said container; mounting said dispensing container in an inverted orientation on the entrance spout of a filter apparatus having entrance and exit spouts with the internal surface of said dispensing container neck opening abutting the external surface of said entrance spout; mounting said filter apparatus on a storage container to discharge water from said exit spout into said storage container; and pooling water from said dispensing container about said entrance spout to prevent water overflowing from said filter apparatus.
