In order to remove as much juice as possible from citrus fruit, a ridged rounded cone that fits inside the halved fruit can be used. From the outside of the fruit, pressure alone, or pressure and rotation combined, squeeze out the juice, seeds, and some of the pulp. Such a ridged cone is called a “reamer”; it is usually fitted with a raised slotted rim to separate seeds from juice and is either positioned over a receptacle or is designed as an all-in-one saucer with handle and pouring lip. Most are molded glass or plastic; the first patented one dates to 1889.
