You’ve probably seen it a hundred times—that large dent on the side of a plastic milk jug. It looks random, maybe even like a flaw in the design. But in reality, that simple indentation is doing far more than you might expect.
In this video, we break down the real reason behind that dimple and how it helps make milk jugs stronger, cheaper, and more efficient. From structural support and material savings to pressure control and even visual design, this small detail plays a surprisingly big role in everyday packaging.

I didn't know about how the dimple affected the integrity of the jug itself. I thought it was there to take the milk to the top of the jug when filling to keep air out maintaining the freshness until the seal was broken. And of course, it would provide the ability for the jug to expand and contract as the jugs got shuffled around until and while you have it at home. I suppose I was half right. Dimples are cute. I bet Kirk Douglas got a lot of dates with his dimple.
