Beverage brewing

Abstract

Systems, methods and apparatus for brewing coffee are provided. The apparatus may include a first film and a second film. A filter may be disposed between the first film and the second film. The filter may retain an amount of material. The first and second film may be flexible. The first film may be pierced by a brewing needle. The second film may be pierced by a drain needle. The second film may be sealed to the first film along a perimeter defined by the first film. The first film may have a flat configuration. The second film may have a concave surface that faces the first film. The filter may define an annular material holding region. The filter may define a drainage region that is coaxial with the filter. The filter may form a layer parallel to and supported by the first film in an area of the first film that overlies the drainage region.

1 . Apparatus comprising:
 a first film;   a second film; and,   disposed between the first film and the second film, a filter that is configured to retain an amount of material.   
     
     
         2 . The apparatus of embodiment 1 wherein the first film is flexible. 
     
     
         3 . The apparatus of embodiment 1 wherein the second film is flexible. 
     
     
         4 . The apparatus of embodiment 1 wherein the first film is configured to be pierced by a brewing needle. 
     
     
         5 . The apparatus of embodiment 1 wherein the first film includes a vapor barrier. 
     
     
         6 . The apparatus of embodiment 1 wherein the second film is configured to be pierced by a drain needle. 
     
     
         7 . The apparatus of embodiment 1 wherein the second film includes a vapor barrier. 
     
     
         8 . The apparatus of embodiment 1 wherein:
 the first film defines a perimeter; and   the second film is sealed to the first film along the perimeter.   
     
     
         9 . The apparatus of embodiment 1 wherein:
 the first film has a flat configuration; and   the second film has a concave surface that faces the first film.   
     
     
         10 . The apparatus of embodiment 1 wherein the filter defines an annular material holding region. 
     
     
         11 . The apparatus of embodiment 1 wherein the filter defines a drainage region. 
     
     
         12 . The apparatus of embodiment 11 wherein the drainage region is coaxial with the filter. 
     
     
         13 . The apparatus of embodiment 11 wherein the filter forms a layer parallel to and supported by the first film in an area of the first film that overlies the drainage region. 
     
     
         14 . The apparatus of embodiment 11 wherein the filter defines a central hole having a perimeter that is coincident with a top of the drainage region. 
     
     
         15 . A method of manufacturing a brewing packet, the method comprising:
 providing a first film;   forming an annular well from a filter;   attaching the well to the first film; and   sealing a second film to the first film to enclose the well.   
     
     
         16 . The method of embodiment 15 wherein the sealing includes heat sealing. 
     
     
         17 . The method of embodiment 15 wherein the attaching includes heat sealing. 
     
     
         18 . The method of embodiment 15 further including, before the sealing, placing beverage material in the well.
