Abstract

A cartridge may comprise a container, a filter, and a lid. The container may comprise a pierceable bottom portion structurally configured to be pierceable by a first machine piercing element. The filter may be disposed inside the container. The filter may comprise a pre-shaped concave center portion disposed above the pierceable bottom portion. The pre-shaped concave center portion may be disposed above the pierceable bottom portion. The pre-shaped concave center portion may comprise one or more attachment portions fastened to the container bottom along a periphery of the pre-shaped concave center portion. The lid may be attached to an opening of the container.

Claims

exact text as granted — not AI-modified
1 . A cartridge, comprising:
 a container comprising a pierceable bottom portion structurally configured to be pierceable by a first machine piercing element;   a filter disposed inside the container, the filter comprising:
 a pre-shaped concave center portion disposed above the pierceable bottom portion; and 
 one or more attachment portions fastened to the container bottom along a periphery of the pre-shaped concave center portion; and 
   a lid attached to an opening of the container.   
     
     
         2 . The cartridge of  claim 1 , further comprising a substance disposed in a chamber bounded by the lid and the filter.

 paint;   glue;   a cleaning solution; or   a solvent.   
     
     
         5 . The cartridge of  claim 2 , wherein the substance is configured to interact liquid to form a solution. 
     
     
         6 . The cartridge of  claim 2 , wherein the substance is configured to interact liquid to form a beverage. 
     
     
         7 . The cartridge of  claim 1 , wherein an opening of the filter contacts a sidewall of the container. 
     
     
         8 . The cartridge of  claim 2 , wherein the filter is configured to:
 hold back a majority of the substance; and   pass a majority of a solution formed in response to the substance interacting with liquid in the chamber.   
     
     
         9 . The cartridge of  claim 2 , wherein the cartridge is configured to pass an outflow of a solution through the first machine piercing element. 
     
     
         10 . The cartridge of  claim 1 , wherein the lid comprises a pierceable lid portion structurally configured to be pierceable by a second machine piercing element. 
     
     
         11 . The cartridge of  claim 10 , wherein the container is configured to receive a liquid through the second machine piercing element. 
     
     
         12 . The cartridge of  claim 1 , wherein at least a part of the container comprises an impermeable material.

         14 . The cartridge of  claim 1 , wherein a portion of the filter comprises an impermeable material. 
     
     
         15 . The cartridge of  claim 1 , wherein a portion of the filter comprises a permeable material. 
     
     
         16 . The cartridge of  claim 1 , wherein at least one of the one or more attachment portions are adhesively fastened to the container bottom. 
     
     
         17 . The cartridge of  claim 1 , wherein at least one of the one or more attachment portions are welded to the container bottom. 
     
     
         18 . The cartridge of  claim 1 , wherein at least one of the one or more attachment portions are mechanically bonded to the container bottom. 
     
     
         19 . The cartridge of  claim 1 , wherein at least one of the one or more attachment portions are chemically bonded to the container bottom.
