How Ruben Rausing became a millionaire

And he remains true to his idea. In the 1940s, the founder commissioned his team of researchers to design milk packaging made of coated paper. It should require as little material as possible, be light and of course cheap in order to be able to compete with the glass bottles that were common at the time. Laboratory manager Erik Wallenberg suggests rolling a sheet of paper and folding it into a triangle to create packaging in the shape of a tetrahedron. Rausing is convinced. He registered a patent for the innovation in 1944, invested in the development and implementation of Wallenberg’s idea, founded the company with the obvious name Tetra Pak in 1951 and a year later sold a filling machine to a local dairy: a modest initial success.
