What is Tumbler Cup
The tumbler cup is a vessel that relates to a cup-shaped container. The bottom contact surface is very small, and the cup body can shake when moving. Its characteristics are: the upper part is light and the lower part is hollow, the thickened arc-shaped bottom, the weight is concentrated in the center of the bottom of the cup, the bottom contact surface is very small, and the cup can shake when moving. At the bottom of the cup, there is a small but powerful air valve. With the help of air pressure, the cup is pressed tightly on the table to take the cup, and the force is applied diagonally upwards, and the air valve will automatically unlock, so it won’t be strenuous.

The physical principle of friction (similar to the tentacle sucker principle of gecko and octopus).
At the bottom of the cup, there is a small but powerful air valve. With the help of air pressure, the cup is pressed tightly on the table to take the cup, and the force is applied diagonally upwards, and the air valve will automatically unlock, so it won’t be strenuous.
It relies on its own attractive force to squeeze out the air between the contact surface, and uses atmospheric pressure to increase the pressure between the contact surfaces to increase friction and prevent the placed object from slipping off. When in use, the smooth side faces down, that is, the smooth side is in contact with the instrument panel. There is a bumpy texture, or the side of the text pattern is facing up.
