Purpose of the Circular Dent on Milk Jugs

Why Milk Jugs Have a Dent It’s Not a Flaw — It’s Smart Design: Pressure Buffer: Absorbs expansion from temperature changes to prevent cracking. Shock Absorber: Helps the jug survive drops without splitting. Structural Strength: Reinforces the jug using less plastic.Spoilage Signal: A bulging dent can warn of spoilage due to gas buildup.Why a Circle? Circles handle pressure better—no stress points, easy to mold, strong and efficient.
Eco Impact: Less plastic, lighter for transport, easier to recycle = more sustainable. Next time you pour milk, salute the dent. Quietly saving your fridge, your floor, and maybe even the planet
