A single serving filter paper cup for making a brewed beverage. The filter paper cup includes a receptacle having a rim captured between an adapter base and lid. The receptacle is formed by pleats in a receptacle wall and the rim around the top of the receptacle wall. Preferably, a heat seal filter paper is used and the pleats are adhered by the heat to retain shape. The receptacle is inserted into an adapter and brewing material is placed into the receptacle. The cover is folded over the rim and an adapter lid is attached to the adapter. The adapter lid and body sandwich the cover and receptacle rim to hold the filter paper cup against the lid to pack the brewing material against the lid and facilitate injection of hot water into the brewing material.

A method of assembling a single serving beverage brewing capsule, the method comprising: manufacturing a filter paper cup comprising the steps of: providing water permeable material;cutting a greater diameter flat circular lower portion from the water permeable material;shaping the lower portion to form a floor and walls creating a downward concave cup shaped receptacle to receive and hold a single serving of brewing material;forming a generally flat annular rim of the lower portion, surrounding an upward opening of the receptacleinserting the filter paper cup into a reusable adapter body;placing a single serving of brewing material into the filter paper cup;capturing the annular rim between a reusable adapter lid and the reusable adapter body; andcompleting assembling the single serving beverage brewing capsule outside and independent of a coffee maker. 2. The method of claim 1, wherein shaping the lower portion to form the receptacle and rim comprises creating folds in the lower portion to create pleated walls and a pleated annular rim. 3. The method of claim 2, wherein shaping the lower portion to form the receptacle and rim comprises heating and shaping the lower portion to create the folds in the lower portion to create pleated walls and a pleated annular rim. 4. The method of claim 3, wherein shaping the lower portion to form the receptacle and rim comprises heating and shaping the lower portion made from heat sealable filter paper to create the folds in the lower portion to create pleated walls and a pleated annular rim and to adhere adjacent layers of the folds to each other to better retain the shape of the receptacle and rim. 5. The method of claim 1, wherein: cutting a greater diameter flat circular lower portion comprises cutting the greater diameter flat circular lower portion and a cover comprising a smaller diameter flat circular upper portion, hingedly connected to each other by a hinge, from a single piece of the water permeable material,and further including, after placing a single serving of brewing material into the filter paper cup: folding the cover over the lower portion, andcapturing the annular rim comprises capturing the annular rim and outside edge of the cover between an adapter lid and the adapter body; andholding the cover taut to facilitate puncturing the cover for injecting heated water into the filter paper cup. 6. The method of claim 5, wherein attaching the adapter lid to the adapter body using features of the adapter lid and adapter body to sandwich the annular rim of the receptacle and the outer edge of the cover between the adapter lid and the adapter body is the sole method of sealing the filter paper cup. 7. The method of claim 6, wherein attaching the adapter lid to the adapter body using features of the adapter lid and adapter body to sandwich the annular rim of the receptacle and the outer edge of the cover between the adapter lid and the adapter body is the sole method of retaining the brewing material in the filter paper cup. 8. The method of claim 5, wherein: the adapter base includes a spring and platform reaching at least half of the distance from the bottom of the adapter body into the adapter in the absence of the rimmed single serving beverage brewing cup in the adapter; andthe spring and platform push the rimmed single serving beverage brewing cup residing in the adapter body upward against the adapter lid to tamp the brewing material. 9. A method of assembling a single serving beverage brewing capsule, the method comprising: obtaining a filter paper cup comprising: a concave receptacle formed from a flat circle of heat sealable filter paper, the receptacle shaped to receive and hold a single serving of brewing material, the receptacle comprising: a floor;pleated walls reaching upward from the floor to an upper opening, first pleats of the pleated walls are a product of forming the receptacle from the flat circle of heat sealable filter paper, the first pleats adhered to adjacent ones of the first pleats by adhesive in the heat sealable filter paper; andan outward reaching pleated rim at the upward opening of the walls, second pleats of the pleated rim a product of forming the rim from the flat circle of the heat sealable filter paper, the second pleats adhered to adjacent ones of the second pleats by the adhesive in the heat sealable filter paper;inserting the filter paper cup into a reusable adapter body, the adapter body comprising: a flat base; andwalls rising from the base;placing a single serving of brewing material into the filter paper cup; andcapturing the annular rim of the concave receptacle between a reusable adapter lid and the adapter body, the adapter lid comprising: a flat top;a passage for injection of liquid into the adapter body; anda downward reaching cylindrical edge;advancing the downward reaching cylindrical edge of the adapter lid into the adapter body; andengaging the downward reaching cylindrical edge of the adapter lid with the adapter body to attached the adapter lid to the adapter body to form the single serving beverage brewing capsule outside and independent of a coffee maker. 10. A method of assembling a single serving beverage brewing capsule, the method comprising: obtaining a filter paper cup comprising: a concave receptacle made from water permeable material shaped to receive and hold a single serving of brewing material, the receptacle comprising:a floor;walls reaching upward from the floor to an upper opening; anda rim at an upward opening of the walls;obtaining an adapter comprising: an adapter body; andan adapter lid attachable to the adapter body by cooperation of features of the adapter lid with features of the adapter body;inserting the filter paper cup into the adapter body;placing a single serving of brewing material into the filter paper cup; andattaching the adapter lid to the adapter body, including capturing the annular rim between the adapter lid and the adapter body to assemble the single serving beverage brewing capsule outside and independent of a coffee maker. 11. The method of claim 10, wherein obtaining a filter paper cup comprises obtaining the filter paper cup including a cover having about the same perimeter as the rim, and the method further includes: after placing a single serving of brewing material into the filter paper cup, folding the cover over the filter paper cup; andcapturing the annular rim between the adapter lid and the adapter body comprises capturing the annular rim and outside edge of the cover between the adapter lid and the adapter body. 12.
