The concept is the bottle to allow drinking without screwing and unscrewing a cup. It opens with just one motion of raising it. It stays closed and not allow leaking when it’s been held by a person who is doing some physical activity. But when it’s lifted to drink, then it opens and the liquid flows. This has been achieved by closing the hole for the liquid on the inner side and opening it by the motion of lifting the bottle when drinking.
There are several factors that determine motion of a body - velocity, time, acceleration, etc. One more thing should be taken into consideration that determines it too - pivot point. But if that point is also moving, then all the bodies form a mechanical chain.
Many examples of a chain motion could be seen in nature. That same principle has been used in an electric motor in order to increase its rotation velocity and other parameters.
