Claim 3

The coffee maker of claim 1, wherein said coffee maker is adapted for use in a microwave device, and wherein said upper reservoir is defined by generally cylindrical microwave permeable walls, and is open at its top for receiving water.

Claim 4

The coffee maker of claim 2, wherein said microwave permeable walls comprise polypropylene, coated expanded styrene foam, polyethylene or polyurethane coated paper board.

Claim 5

The cpffee maker of claim 1, wherein said non-toxic meltable substance is a wax or plastic material which melts at a temperature of about 170° F. to 210° F.

Claim 6

The coffee maker of claim 4, wherein said non-toxic meltable material is a natural or synthetic wax.

Claim 7

The coffee maker of claim 1, wherein said partition includes a plurality of perforations sealed by said non-toxic meltable substance.

Claim 8

The coffee maker of claim 1, including means thereon for resting said container on the receptacle.

Claim 9

The coffee maker of claim 1, wherein said reservoir has a breadth which is greater than said lower compartment, and wherein the lower end of said reservoir includes means adapted to position said container on the receptacle therebelow.

Claim 10

The coffee maker of claim 1, wherein said filter element includes a chamber therein of sufficient size to hold and allow the expansion of the coffee grounds without compacting thereof during brewing.

Claim 11

The coffee maker of claim 1, wherein said filter element includes a microwave barrier which inhibits the roasting of coffee grounds therein during brewing.

Claim 12

The coffee maker of claim 1, wherein said filter is formed from paper secured to said filter element after a pre-measured amount of coffee is placed therein.

Claim 13

The coffee maker of claim 1 including a tabbed freshness seal is removably affixed to said filter below and spaced therefrom.
