Tupperware partyEarl Silas Tupper introduced the range of plastic containers in the USA in 1946. Their trademark was the distinctive “burping” seal. In the early 1950s the Tupperware  party became the unique marketing method. The first Australian Tupperware party was held by Mary Paton in her mother’s home in Camberwell, Melbourne. Mary’s sister Ruth became the first Australian Demonstrator.
