Tetra Pak.

The article discusses the history of the Tetra Pak packaging. Tetra Pak first appeared in Great Britain in 1958 when Calypso introduced an orange drink called Jubbly. The Jubbly carton was considered a manufacturing breakthrough that made Tetra Pak the biggest packaging maker in the world and its Swedish manufacturer, Ruben Anderson, one of world's richest people. In 1963, the tetrahedron was joined by the more traditionally shaped Tetra Brik, which became Tetra Pak's biggest seller.
