In the Soviet Union, milk was often poured into containers, which were popularly called "pyramids" or "triangles". This packaging had its pros and cons. The pyramid could not tip over, therefore, milk was not spilled. But, such a container was made of waterproof cardboard, the "pyramid" could not be handed over to the reception point, like a glass milk bottle, and get 15 kopecks for it.
How did milk pyramids appear? And why exactly milk was poured into them, and not lemonade, for example? It all started in April 1930, when the French popular science magazine "La Science et la Vie" published an article describing the unusual properties of the pyramids. It is not for nothing that the tombs of the ancient Egyptian pharaohs had just such a shape.
But the date of the magazine's release (April!) Was a little alarming: was this information a common joke of journalists? But, soon many publications began to publish articles by the French chemist and science fiction writer Jacques Bergier. Jacques Bergier, aka Jacob Berger, was born in 1912 in Odessa. During the Civil War, the family moved to Paris, where the young man graduated from the Higher Chemical School.
In his articles, Bergier claimed that he carried out many experiments with pyramids made of cardboard and made interesting observations. In such structures, the meat remained fresh for a long time, the blood did not clot. This means that such packaging will be ideal for storing food.
This idea was taken up by Swedish inventor Eric Wallenberg. He decided to start the production of milk cartons. Moreover, waterproof cardboard was developed back in 1915 by John Warner from the USA. True, such a container had significant drawbacks: the production was quite expensive, the cardboard was often torn, and the milk was stored for a short time. But Wallenberg decided that the shape of the pyramid would correct all these flaws. Milk will not turn sour, and people who have consumed it will receive a charge of cheerfulness and optimism.
In 1944, the first pyramid-shaped milk packaging appeared in Sweden. But, not everything was so simple. Problems began with the fact that it was very inconvenient to put the pyramids in ordinary rectangular boxes. They even had to set up the production of special hexagonal containers. But this circumstance was not the most offensive: milk was stored no better than in ordinary packaging. Already in 1959, Sweden abandoned such production.
It is interesting that it was at this time in the USSR that they only became interested in such technology. The Swedes willingly supplied equipment to the Soviet Union, and milk in pyramids became one of the symbols of Soviet grocery stores. Not only milk was poured into the pyramids, but also cream with kefir. Moreover, the capacity of the pyramids was different - from 300 to 500 g. Such packaging successfully existed until the collapse of the Soviet Union. Even in spite of the fact that it was inconvenient to carry it from the store: the edges of the pyramids protruded from the staples and tore the plastic bags. Now rectangular packaging has become much more popular. Moreover, no useful properties of milk from the pyramids have been discovered.
