Today’s invention is a one-piece, injection moulded drip-tray/coaster. It’s designed so that the circular opening in the top is wider than a cup’s diameter. A simple internal spring is moved aside when a cup or glass is placed in it and subsequently grips the cylindrical body of the cup.
This means that the coaster stays attached to the cup, even when someone is drinking from it. Drips on the sides or bottom of the cup are retained inside the U-shaped inner profile of the coaster.
After drinking, the coaster can be removed and dishwashed with the cup.
