Menstrual Cups

Patent for a “Splash-proof menstrual cup”

Someone pointed me to this today – it’s a Korean patent from 2009/2011 for a menstrual cup that has what appears to be a “lid” across the top, that would allow blood into the cup, but (presumably) not allow it to leak out as easily.


I haven’t ever seen a cup like this, so I don’t think they were ever produced.

Much like the Keeper’s patent, which featured a hollow tube stem with a stopper to allow it to be emptied while worn – which doesn’t seem to have ever been manufactured.
