The Design Specifications for the Paper Cup Holders
It is very inconvenient to pass on water, especially hot water, to many people back and forth by hand. This design is to carry many paper cups filled with water, especially hot water, at one time without being burned. The device is composed of many uniset hooked holders and a poriferous rotation axis which can be folded for stock and rotated for use with much convenience.
