Until the middle of the 20th century they were made of sturdy wood and were used after shipping for a wide range of reuse applications.

For example, James Spangler made the first effective vacuum cleaner from an old fan motor attached it to a soap box stapled to a broom handle, using a pillow case as a dust collector. See my blog on the prototyping and the  first vacuum cleaner patent on February 18, 1901.
