We took design concept from idea of preventing wasting water, we added hight adjustment function. The way of opening the stopper portion, we applied snap structure to prevent the contents from leaking. In the body part, we made a vertical window and marked measurement. When you turn the bottom, throttle, controling hight and spiral shape which is inside the tumbler, engages each other so it makes the height adjustable. Throttle, controling hight is covered with rubber so it can prevent liquid coming down. To use it easy to control up and down we have used principle of screw. Therefore, we can get just amount of we want without wasting.
