Patent for Flex-Straw

Joseph Friedman earned U.S. Patent 2,094,268 for his "drinking tube," or flexible straw. When inventors describe their inventions for patents, they try to use broad words like "tube" instead of specific ones like "straw" so their patents cover a range of inventions--including ones that other people may invent later.
