You’ve probably noticed it countless times—a circular dent on the side of your milk jug. It’s one of those everyday features that most people barely give a second thought. At first glance, it might look like a random design quirk or even a manufacturing flaw. But what if I told you that this little indentation actually serves a crucial purpose?
Yes, that seemingly insignificant dent plays a vital role in keeping your milk safe and your jug intact. Intrigued? Let’s dive into the fascinating story behind this clever design feature and discover why it’s more important than you might think!

But as manufacturers perfected the plastic jug, they faced a new challenge: how to maintain structural integrity without using excessive plastic. That’s where the circular dent came into play.
