Abstract
Abstract A coffee brewing means having a downwardly directed discharge spray head for hot water recessed in a surface, and a holder for prepackaged coffee for positioning the package under the spray head and underlying the surrounding surface in proximity thereto so that upon initial wetting of the coffee, the resulting expansion of the coffee presses the upper side of the package against the surface surrounding the spray head and forms a seal therewith so that the water issuing from the spray head is confined to flow through the package.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
121 words
A brewing apparatus for a package formed of filter material and containing a measured amount of coffee, said apparatus comprising: a. means forming a downwardly facing surface provided with at least one continuous downward projection; b. a hot water spray head mounted on said surface; c. means for supporting a coffee brewing vessel under said surface; and d. a container dimensioned to receive said package and place the upper end surface thereof in confronting relation to said spray head and a surrounding portion of said downwardly facing surface, whereby on wetting the coffee contained in said package, said coffee swells and the upper surface of said package engages said downwardly facing surface thereby to form a seal surrounding said spray head.
Claim 2
Dependent Claim
121 words
A brewing apparatus for a package formed of filter material and containing a measured amount of coffee, said apparatus comprising: a. means forming a downwardly facing surface provided with at least one continuous downward projection; b. a hot water spray head mounted on said surface; c. means for supporting a coffee brewing vessel under said surface; and d. a container dimensioned to receive said package and place the upper end surface thereof in confronting relation to said spray head and a surrounding portion of said downwardly facing surface, whereby on wetting the coffee contained in said package, said coffee swells and the upper surface of said package engages said downwardly facing surface thereby to form a seal surrounding said spray head.
Claim 3
Dependent Claim
26 words
A brewing apparatus, as defined in claim 1, wherein: a. said downward projection is an annular shoulder sealingly engaged by said package as said coffee swells.
Claim 4
Dependent Claim
31 words
A brewing apparatus, as defined in claim 1, wherein: a. means is provided on said downwardly facing surface for deflecting downwardly water tending to pass between said surface and said package.
Claim 5
Dependent Claim
30 words
A coffee brewing apparatus, as defined in claim 1, wherein: a. said brewing vessel includes inwardly directed step means; and b. said container is supportingly received upon said step means.
Claim 6
Dependent Claim
138 words
A coffee brewing apparatus for a flexible package of filter material having a charge of coffee therein, comprising: a. means forming a downwardly facing surface; b. a hot water spray head mounted on said surface; c. means for supporting a coffee brewing vessel under said surface; d. a coffee brewing vessel having an outlet at its lower end for discharge of coffee and including means for holding said package in close proximity to said spray head and the surrounding downwardly facing surface, whereby on wetting said coffee, said coffee swells thereby to force the upper side of said flexible package into sealing engagement with said surface; and e. a deflecting means depending from said surface and located principally beyond the margins of said package for deflecting into said vessel any water passing between said surface and said package.
Claim 7
Dependent Claim
138 words
A coffee brewing apparatus for a flexible package of filter material having a charge of coffee therein, comprising: a. means forming a downwardly facing surface; b. a hot water spray head mounted on said surface; c. means for supporting a coffee brewing vessel under said surface; d. a coffee brewing vessel having an outlet at its lower end for discharge of coffee and including means for holding said package in close proximity to said spray head and the surrounding downwardly facing surface, whereby on wetting said coffee, said coffee swells thereby to force the upper side of said flexible package into sealing engagement with said surface; and e. a deflecting means depending from said surface and located principally beyond the margins of said package for deflecting into said vessel any water passing between said surface and said package.
Claim 8
Dependent Claim
21 words
A coffee brewing apparatus, as defined in claim 5, wherein: a. said deflecting means is a step depending from said surface.
Claim 9
Dependent Claim
22 words
