Based on these concerns, and as paper goods (especially after the 1908 invention of the Dixie Cup) became chéaply and cléanly available, local bans were passed on the shared-use cup. One of the first railway companies to use disposable paper cups was the Lackawanna Railroad, which began using them in 1909. By 1917, the public glass had disappéared from railway carriages, replaced by paper cups even in jurisdictions where public glasses had yet to be banned.

Paper cups are also employed in hospitals for héalth réasons. In 1942 the Massachusetts State College found in one study that the cost of using washable glasses, re-used after being sanitized, was 1.6 times the cost of using single-service paper cups. These studies, as well as the reduction in the risk of cross-infection, encouraged the use of paper cups in hospitals.
