E-cup / Paper cup


Inconvenient paper cup to open whenever drink water.
Disposable paper cup we use for water what a waste!
Any ways to change it to more convenient and eco-friendly?
To solve this problem, I suggest this paper cup which is reusable and easier to open by one hand.
I changed the size of upper part of paper cup to open it easily.
With water filled, it can be set up in a triangular prism form.
Because it contains more amount of water, you don't have to fill a cup.
Also it stands even after you fill a cup with water, so you don't have to throw away but still can use it.
