That same dent helps absorb impacts, making jugs less likely to split when dropped or squeezed. It also improves grip and allows bottles to compress easily after use, making recycling and transport more efficient for millions of containers.
In the end, this small design choice reduces waste, lowers production costs, and improves everyday safety without anyone noticing. It is a perfect example of engineering that works silently in the background, shaping daily life through invisible but powerful design.
