Tupperware: the sociological box
In 1946, nine years after the discovery of polyethylene, Earl Tupper, an American citizen, began manufacturing small airtight injection-moulded polyethylene bowls aimed at "making women's work easier".
The Wonderful Bowls' sealing system entails creating a vacuum by pressing on the lid, and therefore helps preserve food in optimal conditions. As sales of the first line of Tupperware were not taking off, Brownie Wise, a door-to-door sales representative, convinced Earl Tupper in 1951 to change the distribution model and to launch the famous "Tupperware home parties". This would be the beginnings of worldwide success that hasn't faltered since.
Over 60 years later, the brand has changed, diversified its product lines and is now involved in freezer storage, and oven and microwave cooking.
The small airtight box has come a long way and was able to adapt to new uses and lifestyles while keeping the same motto: making life easier.
