Why was the milk in triangular bags?
This is the version the blogger told:
The authors of the article in “La Science et la Vie” frolicked enough over people's belief in such quackery. They reported, in particular, that sleep in the correct tetrahedron rejuvenates, the razor blades inside it self-sharpen, and the milk does not turn sour. They laughed - and forgot.
But this number a few years later caught the eye of the Swedish inventor Eric Wallenberg, a laboratory worker Åkerlund Rausing,who imbued with the idea of reducing the loss of milk traders. In 1944, a prototype cardboard packaging in the form of a tetrahedron was first born. And six years later, AB Tetra Pak was born, whose original packaging for a long time was the Tetra Classic® cardboard pyramid.
A huge advantage of such packages was a minimum of waste during production and its almost complete automation. The base — soft cardboard connected to polyethylene — was rolled into a cylinder, the junction of opposite ends was thermally welded, then milk, kefir or cream was poured inside, after which the machine made two more thermal seams and cut the finished packaging, which safely fell into a special container. No difficulty and almost no loss.
True, everything further on the way to the buyer was not so technological. One of the major drawbacks of tetrahedron packets was the absolute impossibility of packing them tightly in rectangular boxes. Therefore, special hexagonal containers were used to store the dairy products packaged in pyramids. But this led to an unreasonable increase in transportation and storage costs - it was necessary to transport and store air to a large extent.
And then it turned out that the milk in the pyramids sour almost in the same way as in any other package. That is, there were no rational reasons for maintaining adherence to this packaging, despite all its simplicity in production.
As a result, Sweden already in 1959 began to abandon the Tetra Classic® milk tetrahedra.
It seemed the company had no choice but to leave the market. But its leader, Ruben Rausing, was able to sell his technology to the Soviet Union. It is said that the long-standing article from La Science et la Vie played a role in convincing Soviet ministers. However, they may be led to the apparent cheapness of production.
And the second, very long, life of the triangular milk packages began. They were used in the USSR for almost 30 years, until the mid-1980s.
They write that their quality was rather average. Pyramids are often torn and leaked. Although they say the bottle and fought not quite less. Trade accustomed to write off losses at cost. In carrying and storage such packages were also inconvenient. In general, cost-effective production turned out to be quite burdensome in the long run. Of course, on the scale of a huge country it was all a trifle.
But there was an interest to buy unusual bags to residents of distant regions
By the way, a week ago a hurricane turned out to have demolished the mystical pyramid of Golod:
“From the powerful gust of wind, the pyramid should have developed inward,” says Alexander Golod. “However, she just fell on her side.” Despite its large mass, its structures were weakened (it was made of wood, covered with fiberglass). Fortunately, no one was hurt. Our guards are instructed to this effect and, in advance, literally 5 minutes before the fall, took all the visitors, there were several of them, to the street. Our building collapsed on an ostrich farm, located nearby, but everything was okay there. The pyramid fell on one of the ostriches, but, fortunately, he survived.
Hunger, he said, was not too worried about what had happened, since he himself soon intended to demolish the old version of the pyramid and build a new, already capital, version 2.5 times higher than the previous one.
In general, I used to think that it was for the purpose of losing weight that the pyramid was like that. And it turns out this is the name of the person who built it.
The Pyramids of Golod are structures designed by Russian engineer Alexander Golod. They refer to the so-called "energy pyramids", which in occultism are considered to be converters or accumulators of some unknown "bioenergy" science.
A distinctive feature of the Golod's pyramids is that the proportion of the golden section in them is applied to the ratio of the diameters of adjacent balls sequentially inscribed in a regular four-sided pyramid. When this condition is fulfilled, the ratio of the height of the pyramid to the side of the square lying at its base is ≈ 2.058, and the angle between the faces of the pyramid is ≈ 27.3 °, which gives it a characteristic sharp-pointed appearance.
