  • Patent number: 5047252
    Abstract: A beverage infusion device for preparing an individual cup of an infusible beverage such as coffee and tea. The device includes one or more porous pouches containing infusible material permanently or removably secured to a rotatable, hand held shaft, with the pouches extending radially outwardly from the shaft and dimensioned to fit within a conventional beverage cup or mug. In use, the device is inserted in a cup of hot water and the shaft is rotated between the thumb and finger of the user in alternating clockwise and counter-clockwise directions. Upon rotation of the shaft and the pouches secured to the shaft, a centrifugal flow pattern is created in water which enhances the efficiency of extraction of the infusible material. When the pouches are permanently secured to the shaft, the entire device is discarded after use. When the pouches are removably secured to the shaft, the pouches are separated from the shaft after use and discarded, with the shaft portion of the device being reusable.
