Tupperware is the name of a home products line that includes preparation, storage, containment, and serving products for the kitchen and home. It also includes plastic containers used to store goods and/or food. In 1942, Earl Tupper developed his first bell-shaped container; the brand products were introduced to the public in 1948. 

Tupperware was developed in 1946 by Earl Silas Tupper (1907–83) in Leominster, Massachusetts. He developed plastic containers used in households to contain food and keep it airtight. The once-patented "burping seal" is a famous aspect of Tupperware, which distinguished it from competitors. Earl Tupper invented the plastic for Tupperware already in 1938, but the product only worked with the emergence of the sale through a presentation in a party setting. In 1949, Tupperware introduced the 'Wonderlier Bowl' that gave a start to a revolutionary range of kitchen utensils.
