Double-hole Vacuum Cup / Living

Double-hole Vacuum Cup
Double-hole Vacuum Cup

We all know, due to the principle of thermal expansion and contraction, the cup filled with hot water will be difficult to open due to the pressure difference in and outside the cup. To solve this problem, we designed "Double-hole Vacuum Cup". The cover of the cup is designed to have two layers, with small holes on each layer. The function of the holes is to eliminate the pressure difference in and outside the cup. This design can help you easily drink from the cup, and no longer have the trouble failing to open the cup.
