Ever drank coffee and wondered how on earth is the coffee still hot ?
In this post, we’ll dive into the science of insulated cups, how they work and why they’re essential for the best coffee experience !
How Insulated Coffee Cups Work
Insulated coffee cups use materials and structural designs that reduce heat transfer. Here are some common insulation methods:
-
Ripple Wall Design
Ripple wall cups have an outer layer with ridges that create air pockets. This ripple design not only provides extra insulation but also keeps the cup cooler to the touch, so customers can hold hot drinks comfortably. The air pockets reduce heat loss by creating a barrier between the hot liquid and the outer surface. -
Triple Wall Structure
Triple wall cups have three layers: an inner layer in contact with the beverage, a middle insulating layer, and an outer layer. The middle layer often contains air or other materials that minimize heat loss, helping to keep drinks hot longer. -
Double Base Layer
Some insulated cups, like the triple wall double base, have an additional base layer. This extra layer reduces heat transfer at the bottom of the cup, which is where the highest concentration of heat is often lost. This feature is perfect for customers who enjoy savoring their drink slowly, as it provides an even longer-lasting warmth.
