I'm working on a zine about menstrual cups and while I've been sifting through the info in this community for a few hours now, I haven't found much on the history of menstrual cups. On Wikipedia it says the first cup was patented in 1932 and that The Keeper was manufactured in the US in 1987 [making it the same age as me, haha]. From what I read in the FAQ, there was some kind of legal dispute over the 'Moon Cup' name and I'm wondering which -company- actually came first.
Also, does anyone know anything about the older cups? All it says in Wiki is that they were made of rubber and were bell-shaped.
Basically, I'd like to mention which of the current companies offering cups was the 'first', so to speak. I was completely unaware that cups have been being made since the 30s though, and I'd be very interested in finding more information about those!
