BioPod: Single-use Filter Pod

Abstract

This invention provides a single-use biodegradable beverage brewing-pod for use in high-pressure, high-heat beverage brewing machines with inlet and outlet probes, such as Keuring, Cuisinart and functionally similar machines. This disposable single-use device allows consumers to use their own dry ingredients (e.g., coffee, tea, etc.). The invention consists of a lid and a brewing chamber that has at least one window covered with a biodegradable filter window. The size of the filtered window(s) is calculated to allow even and slow flow of the beverage through the filter(s). The tightly placed lid prevents back-flow of the brewing beverage. While the solid bottom part of the brewing chamber blocks the path of least resistance, the biodegradable filter slows the brewing process. The slow brewing process will produce a full-bodied beverage. After its use, the entire pod and its content can be disposed without harming the environment.

The principal embodiments of the invention claimed are defined as follow: 
     
         1 . The single-use disposable beverage brewing-capsule of this invention consists of:
 (i) a biodegradable lid to prevent backflow of the brewing beverage;   (ii) an integrated biodegradable hard shell for filling and holding the dry beverage medium (such as coffee, tea, etc.); and   (iii) a window(s) that is covered with a biodegradable filter on the side of the hard shell for releasing the brewed beverage while retaining the dry beverage medium.   
     
     
         2 . The size and the number of the filter-covered window(s) are computed for the slow and even release of full-bodied brewed beverage. 
     
     
         3 . The solid bottom of the brewing chamber blocks the path of least resistance that is created by the brewing machine's high pressure hot water.
