Ever meet somebody who has had a serious impact on your life? I have met several people like this; most recently is one of our new Donner-Mae inductees, Kari-Mae. Let me show you...
Yep, I had no idea and I bet some of you didn't either! So, let's consult the Internets for a little history:
An early version of a bell-shaped menstrual cup was patented in 1932. Later menstrual cups were patented in 1935, 1937, and 1950. The Tassaway brand of menstrual cups was introduced in the 1960s, but it was not a commercial success. Early menstrual cups were made of rubber;[ today, both silicone and rubber models are available.
In 1987, another latex rubber menstrual cup, The Keeper, was manufactured in the United States. This proved to be the first commercially viable menstrual cup and it is still in manufacture today. The first silicone menstrual cup was the UK-manufactured Mooncup. Most menstrual cups are now manufactured from medical silicone because of its durability and hypoallergenic properties. The German brand MeLuna is the only company to manufacture their cup out of TPE (thermoplastic elastomer). Menstrual cups are becoming more popular worldwide, with many different brands on the market, and there are different sizes and shapes available.
