Gravity cup with adjustable, interchangeable and disposable tube straw valve

摘要

A gravity cup for drinking fluids, comprising a container defined by sides connected to a base on one end and forming an opening at the other end through which fluid is placed and contained therein, the container having an outlet located at the base such that gravity forces the fluid through the outlet; a valve being ball-shaped and having a passage therethrough in rotationally attached to the container such that rotating the valve regulates the flow of fluid out of the container through the outlet; the valve being operable from fully opened, through partially opened, through fully closed; position an adjustable tube straw connected at its proximal end to the valve such that fluid flowing through the valve flows through the adjustable tube straw to a user for drinking at its distal end, and such that manipulating the adjustable tube straw rotates the ball thereby operating the valve and regulating the rate of flow of fluid from the container through the passage and the adjustable tube straw to the user.
