In the 1930s, Chalmers gave up her profession as a singer and actress to submit a patent on menstrual cups. Because of her invention, which is known as menstrual cup, we can now tackle our period with comfort, freedom, and even satisfaction!

Leona Chalmers, an American author, inventor, and actress, was known as the inventor of the first modern menstrual cups. Chalmers patented a design of period cup - similar to the cups available today - which was made from rubber latex. Although there were menstrual products identical to this, which were called "Catamenial Sacks", she was the first to patent and market the period product.

Moreover, these Catamenial Sacks consists of a cord and a belt. Emptying it is also similar to how you empty a modern menstrual cup. You only need to remove the pouch, empty it, and reinsert it back again afterward.

While Leona Chalmers is considered as the creator of the first menstrual cup, there are some devices before, which doesn't look like a cup that we know today, that offers the same function as modern menstrual cups. And over time, period cups are getting more and more popular.

When you are nervous, your vaginal muscles will tighten. This will make the insertion much difficult than it really is. So, before you begin, calm down and as much as possible, don't panic. Relaxing will allow your vaginal muscles to also relax, which makes insertion quite easy.

Fold your cup the way you want it to be

After folding your menstrual cup, hold it firmly then gently insert it into your vagina. It should pop open easily when you insert it properly. You can feel the "pop" once you successfully put it in. If you can't feel the pop, just give the stem a sharp tug, and if it doesn't move, then the seal is formed and your cup is completely open.

And that's how to properly use a menstrual cup. So, let's now talk about when was menstrual cup invented. Let's proceed below!

The first menstrual cups were invented in 1937 in the United States. Leona W. Chalmers is the one, and the first to patent and sells the device. Due to rubber shortage from World War II and failure to sell rubber cups, Chalmers alongside with her team decided to create a vulcanized rubber - a softer version of the cup.

And below (far left) you can see the drawing of the menstrual cup from Chalmer's patent. You can see that it is very similar to The Keeper, Tassaway, and Tasette that we know today. She suggested that the patented cup should be made of vulcanized rubber - it later became disposable and change its name.
