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.

  1. That stem looks like it would be really irritating.

  2. I always wondered if there is some sort of cotton ball or something that you can put into a cup, so the blood gts absorbed without touching your skin…and without falling out… I always worry that the cup turns and there is a massacre down there…

  3. The problem with adding something like a cotton ball into there, means adding the potential for bacterial growth. Silicone is normally used for the cups because it is non-porous so microbes supposedly can’t stick to it.

  4. Not quite sure where to put this but I think I found a new cup brand on Amazon: – I can’t figure out which cup it resembles. Too rounded and too many grip rings for it to be an iCare/Diva knockoff.

  5. I didn’t put a link to that, because if you look at the additional pictures in the listing, they are for a different shape of cup – so I’m not sure which one they are selling. The first picture appears to be the same shape as one I’ve seen with hearts on the side (
