Ketchup is probably one of the most famous and widely-used sauces around the world. Various studies show that about 96% of Americans always have ketchup in their fridges. However, the popularity of the sauce doesn’t mean its sales have always blossomed – in fact, sales were fairly low in the late 90’s.
The leading producer of the sauce, H.J. Heinz Co., decided it was time to make people consume more ketchup. They started analyzing the problems that could potentially reduce the intake of the sauce and concluded they needed to make the ketchup bottle more convenient, so that people can get the sauce out of it quickly and easily.
As a result, they developed the new upside-down bottle that allows people to get all the ketchup they need without squeezing and poking a knife in the bottle. A man called Paul Brown developed a special valve that released the contents of the bottle when its sides are pressed. His invention was bought by various companies, including Heinz who added it to the new upside-down bottle. Back in 1995 Brown sold his company and his invention brought him $13 million.
