Though the primary purpose is functional, the circles on the bottom of plastic cups also contribute to the design. They add a subtle texture that can improve grip for users, making it easier to hold onto the cup, especially when it’s filled with liquid. This feature also contributes to the overall aesthetic design, giving the cup a distinct look and feel.
In some cases, the circles also serve as part of the identification process for recycling. The markings can help distinguish the material type or the manufacturer’s logo, making it easier for recycling programs to sort the cups correctly.
While the circles on plastic cups might seem like a simple design feature, they actually serve several important purposes that contribute to the functionality, durability, and ease of use of the cups. From ensuring even pressure distribution to making stacking easier and helping with heat dissipation, these small indentations play a crucial role in the design of disposable plastic cups. So, the next time you pick up a plastic cup, you can appreciate the hidden engineering behind those seemingly insignificant circles
