Abstract

A filter paper cup for making a beverage pod. The filter paper cup includes a cover and a base (or receptacle). The filter paper cup is formed by forming pleats in walls and a rim around the tops of the wall. Preferably, a heat seal filter paper is used and the pleats in the walls and rim are adhered by the heat to retain the shape. The base in inserted into a pod holder and brewing material is placed into the base. The cover is folded over the rim, and a lid is attached to the pod holder to sandwich the cover and rim to seal the pod. The cover is held taut by the lid of the pod holder to facilitate penetration of the cover by a needle to inject water into the pod.

First claim

I claim:

1. A packaging material for forming beverage pods, the packaging material comprising:
a receptacle made from water permeable material, said receptacle comprising;
a downward concave cup having a base, pleated walls, and an upper opening and shaped to receive and hold a brewing material; and
a pleated annular rim circling the downward concave cup forming a top closed outside perimeter of the receptacle; and

a generally flat cover hingedly attached to an outer edge of the annular rim, said cover is configured to cover the upper opening and the annular rim of the receptacle, wherein;
the packaging material is made from:
a smaller diameter flat first portion forming the flat cover; and
a larger diameter flat second portion forming the receptacle, wherein forming the downward concave cup of the receptacle from the larger diameter flat second portion creates the pleated walls in the downward concave cup and the pleated annular rim; and

the annular rim and edge of the cover are configured to reside between a lid and body of a holder to seal the packaging material during brewing, the packaging material insertable and removable from the holder for reuse of the holder.

2. The packaging material of claim 1 , wherein:
the water permeable paper is filter paper; and
the receptacle and the cover are a continuous piece of filter paper.

3. The packaging material of claim 1 , wherein the receptacle and the cover are two hingedly attached pieces of water permeable material.

4. The packaging material of claim 1 , wherein the walls of the concave cup are substantially vertical walls including wall pleats.

5. The packaging material of claim 4 , wherein the walls of the concave cup substantially form a frusto-conical surface including the wall pleats.

6. The packaging material of claim 4 , wherein rim pleats in the annular rim are continuations of the wall pleats in the sides.

7. The packaging material of claim 1 , wherein a rim outside diameter of the annular rim is approximately the same size as a cover outside diameter of the cover.

8. The packaging material of claim 1 , wherein the cover is a foil cover hingedly attached to the receptacle.

9. The packaging material of claim 8 , wherein the receptacle is made of heat sealable filter paper and the receptacle forming includes heat to adhere the pleats to adjacent pleats to retain the shape of the concave cup and rim.

10. The packaging material of claim 1 , wherein the receptacle is made of heat sealable filter paper and the receptacle forming includes heat to adhere the pleats to adjacent pleats to retain the shape of the concave cup and rim.

11. The packaging material of claim 10 , wherein the cover is made of heat sealable filter paper.

12. The packaging material of claim 1 , wherein the receptacle has an inner top diameter D 2 of approximately 1.625 inches, an outer top diameter of the rim D 3 of approximately 2.125 inches, and the lid has approximately the same diameter D 3 as the rim.

13. The packaging material of claim 12 , wherein the receptacle has a base diameter D 1 of approximately 1.25 inches and a height H of approximately one inch.

14. The packaging material of claim 1 , wherein the receptacle is made from a mesh material.

15. A filter cup and reusable holder assembly comprising:
the filter cup comprising:
a receptacle made of water permeable material, said receptacle comprising a downward concave cup having pleated walls and shaped to receive and hold a brewing material; and
a pleated annular rim circling a top of the receptacle;

the reusable holder insertable into and removable from a brewing chamber of a coffee maker each time a brewed drink is prepared, and containing the filter cup, the coffee maker accepting disposable brewing cartridges and including a bottom needle for puncturing and carrying brewed drink from the disposable brewing cartridges each time the disposable brewing cartridges are inserted into the brewing chamber, the reusable holder comprising:
a holder base configured to avoid the bottom needle of the coffee maker and not be punctured by the bottom needle, the holder base having openings to release the brewed beverage into the brewing chamber of the coffee maker and not through the bottom needle, thus altering the designed function of the coffee maker; and
a holder lid attached to the holder base, the holder lid having a permanent hole through the center of the holder lid to allow liquid to enter the reusable holder,

wherein the annular rim of the filter cup are sandwiched between the holder base and holder lid to seal the brewing material in the filter cup while brewing the brewed drink.

16. The filter cup and reusable holder assembly of claim 15 , wherein the holder assembly is configured to fit into the brewing chamber configured to accept the disposable brewing cartridge having a frusto-conical shape, a height of about 1¾ inches, a top rim having a diameter of about two inches, a diameter just below the top rim of about 1.8 inches, and a base having a diameter of about 1.43 inches.
