That Dent in Your Milk Jug? It’s Smarter Than You Think. 🥛 Most people overlook the small dent on plastic milk jugs, assuming it’s a flaw—but it’s actually a clever design feature with several important functions.
🔹 Pressure Control:
The dent acts as a “flex zone” to handle the pressure from the heavy liquid and temperature changes, preventing bulging, leaks, or cracks.
🔹 Shock Absorption:
Drop the jug? The dent works like a tiny airbag, absorbing impact and reducing breakage.
🔹 Less Plastic, More Strength:
Like an architectural arch, the dent allows manufacturers to use less plastic while keeping the jug strong—saving money and cutting waste.
🔹 Easier Recycling:
It creates a weak point, making the jug easier to crush and more efficient to process.
So next time you pour a glass of milk, remember: that little dent is a quiet feat of engineering, making your jug safer, greener, and smarter.
