When it comes to rain, use disposable vinyl to prevent runoff on the floor.
Disposable vinyl is one of the main causes of environmental problems such as global warming. So disposable plastic
I thought about the idea of "eco umbrella" that I do not need to use.
If you put an umbrella in the rain, rain water will be put in the cup. When I keep rainwater and go outside again
Pressing the umbrella downward will push the lower part of the umbrella into the groove and the spring and rubber packing will block the rainwater.
There is a gap and the water escapes. If not pressed, the spring pushes the bottom stick again
It is an eco-umbrella with a function to prevent the gap. |
