Unscrewer / Auxiliary Appliance

It is very difficult for some people to unscrew the cap of bottle, especially for the elderly.
Therefore, I designed the Unscrewer for the elderly to slove this problem.
The Unscrewer is using POM material which is a kind of plastic with high strength and stretchy.
The elderly could use Unscrewer by putting the cap in the hole of the Unscrewer when they try to unscrew the cap.
Of course, this could be hung on the key ring when not in use.
