Wax drinking strawIn 1888, the first wax drinking straw and the spiral winding tube-making process was patented by Marvin C. Stone in Washington, DC. Stone was already a manufacturer of paper cigarette holders. His idea was to make paper drinking straws to replace the use of natural rye grass straws. Stone made his prototype straw by winding strips of paper around a pencil and gluing it together. He then tried paraffin-coated manila paper, so the straws would not become soggy while someone was drinking. The first straws were hand rolled, and by 1890 his factory was producing more straws than cigarette holders.By 1905, he had also invented a machine to roll his straws, necessary to keep up with the growing demand, and new applications of spiral-wound tubing. |
