Why Test the Capacity?

When shopping for a silicone lunch box or collapsible container, one big question always comes up:
“Does the labeled 600ml actually hold 600ml, or will it overflow halfway?”

Too often we’ve seen containers that look good on paper but fail in real life. So, to find out the truth, I decided to run a simple but practical capacity test on the Durbl 600ml silicone lunch box.

The Test: Two Bottles of Coca-Cola

For this experiment, I used something everyone knows: two 300ml bottles of Coca-Cola.

  • First bottle (300ml): the container filled up to about halfway.
  • Second bottle (another 300ml): the container reached the top, snug and exact.
  • Double-checked with a measuring cup: total capacity matched perfectly — no exaggeration, no shortfall.

The result: the Durbl 600ml collapsible container truly equals two bottles of Coke.

Everyday Use: Perfect for Office Lunch & Small Kitchens

The numbers tell the truth, but real-life use makes it even better:

  • Foldable food container: Made of flexible silicone, it collapses flat after use, saving space in your bag or kitchen.
  • Lightweight & durable: Much lighter than glass, yet sturdy enough for daily carry.
  • Ideal for light meals: The 600ml size is just right for a fresh salad or a hearty sandwich, perfect for office lunches or meal prep.

Why Choose Durbl?

  • Real capacity → Backed by a hands-on capacity test, 600ml means exactly 600ml.
