US Patent 9795243 Single serving brewing material holder

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.
