The filter paper 252 includes a filter cover 252′. After inserting the filter paper 252 into the base 230b and filling the filter paper 252 with brewing material 41, the filter cover 252′ is folded over the brewing material 41 and the cover 230a is pressed onto the base 230b. A rim 253 of the filter paper 252, and matching rim 253′ of the filter cover 252′ may be sandwiched between the cover 230a and base 230b to securely hold the filter cover 252′ on the filter paper 252 to retain the brewing material 41 in the filter paper 252.
A side view of the filter paper cup 40 with the folding paper lid 40d open is shown in FIG. 79A, a top view of the filter paper cup 40 is shown in FIG. 79B, a second side view of the filter paper cup 40 with the folding paper lid 40d closed is shown in FIG. 7C, and a cross-sectional view of the filter paper cup 40 taken along line 80-80 of FIG. 79B is shown in FIG. 80. The lid 40d of the filter paper cup 40 may be folded over the cup 40 and sealed after loose brewing material 41 is poured into the cup. The filter paper cup 40 includes a receptacle 40g formed from a bottom 40b, sides 40a, and a rim (or annular rim) 40c, and a cover (or lid) 40d for closing the receptacle 40g to capture brewing material in the filter paper cup 40. The filter paper cup 40 is formed using heat and/or moisture to form permanent folds (or pleats) 40f in the sides 40a and rim 40c of the filter paper cup 40 to add strength and rigidity to the filter paper cup 40 so that the filter paper cup 40 retains its shape after forming, and preferably, adhesive is applied to the rim 40c and/or the sides 40a to retain the pleats and add strength and rigidity to the filter paper cup 40. Preferably, the filter paper cup 40 is constructed from heat sealable filter paper having a heat reacting film on at least one side, which film causes the pleats to adhere to adjacent pleats when heat is applied following forming. The pleats in the rim 40c are generally continuations of the pleats in the sides 40a. The filter paper cup 40 may alternatively be corrugated to retain shape. The filter paper cup 40 thus has structure for maintaining a substantially (i.e., within the ability of the paper to maintain a shape) frusto-conical or cylindrical shape unlike known coffee pods with have no structure for maintaining shape and are pillow-like. U.S. patent application Ser. No. 11/392,893 filed Mar. 28, 2006 filed by the present inventor, discloses a similar filter paper cup forming a coffee pod. The '893 application is incorporated by reference above.
The filter paper cup 40 is preferable frusto-conical shaped or cylindrically shaped and more preferably frusto-conical shaped. The filter paper cup 40 has a base diameter D1, an inner top diameter D2, an outer top diameter (the diameter of the rim) D3, and a height H. The diameter D1 is preferably approximately 1.25 inches, the diameter D2 is preferably approximately 1.625 inches, the diameter D3 is preferably approximately 2.125 inches, and the height H is preferably approximately one inch. The rim 40c is thus approximately 0.25 inches wide. The lid 40d has approximately the same diameter D3 as the rim 40c.
The filter paper cup 40 may be sold in an empty state for filling by a user, or as a pre-packages single serving coffee pod. When sold for filling by the user, the filter paper cup 40 is preferably sold with the cover 40d attached to the rim 40c of the receptacle 40g. For example, the filter paper cup 40 may be made from a single piece of filter paper cut into two circular portions attached by a hinge 40h, or by two separately cut pieces of filter paper attached at the hinge 40h. The filter paper cup 40 may be sold as two pieces, where the cover 40d is detached from the receptacle 40g, but may be more difficult to use. A user may seal the cover 40d to the rim 40c of the receptacle 40g as disclosed in the '893 patent, or the cover 40d may be held to the receptacle 40g by sandwiching the filter paper cup 40 between a holder lid 32a and holder body 31. When the filter paper cup 40 is sold as a ready to use pod containing brewing material, the pod is generally manufactured using filter paper off two separate rolls as described below.
A cross-sectional side view of a pod holder 30r showing the pod holder 30r with the tamping spring 36 and bottom tamper 34, the filter paper cup 40 containing a portion of coffee 41, and the holder lid 32a ready to attach to a holder body 31a is shown in FIG. 81A, and a cross-sectional side view of the pod holder 30r the coffee holder with the tamping spring and bottom tamper, the portion of coffee in the filter paper cup, and the holder lid attached to the holder body with the rim of the filter paper cup sandwiched between the lid and coffee holder and the tamping spring and bottom tamper pushing the filter paper cup against the lid according to the present invention is shown in FIG. 81B. The rim 40c rests on a top edge of the holder body 31 and is sandwiched between the holder lid 32a and body 31a when the lid 32a is attached to the body 31a, thereby holding the filter paper cup 40 against the holder lid 32a so that a needle inserted throug h the holder lid 32a will puncture the folding paper lid 40d and inject hot water into the filter paper cup 40. The brewing material 41 is preferably retained in the filter paper cup 40 solely by attaching a lid 32a of the pod holder 30r to the base 31a of the pod holder to sandwich the rim 40c of the filter paper cup 40 and the outer edge of the cover 40d between the lid of the pod holder to the base of the pod holder. U.S. patent application Ser. No. 11/777,831 filed Jul. 13, 2007 filed by the present inventor, describes a similarly pod holder. The '831 application is incorporated by reference above.
The inside diameter D4 of the mouth of the pod holder 30r is approximately the same size as the Diameter D2 of the filter paper cup 40 and is preferably approximately 1.625 inches, thereby facilitating the capture and sandwiching of the rim 40c and edge of the cover 40d between the holder lid 32a and body 31a. Sandwiching of the rim 40c and edge of the cover 40d between the holder lid 32a and body 31a both seals the brewing material in the filter paper cup 40 to prevent or restrict the escape of the brewing material from the filter paper cup 40 during brewing and provides a taut cover 40d facilitating puncturing the cover 40d by a needle used to inject heated water into the filter paper cup 40 during brewing. The body 31a may have a cylindrical or frusto-conical shape.
Another embodiment of the coffee holder 30s is shown in FIG. 82. The coffee holder 30a is similar to the coffee holder 30s but omits the tamping spring 36 and bottom tamper 34.
