Liquid Silicone Menstrual Cup & LSR Menstrual Cup

Liquid Silicone Menstrual Cup, also knows as LSR Period Cup, LSR Menstrual Cup, Female Period Cup, which is a feminine hygiene device that is inserted into the vagina during menstruation. The Menstrual Cup purpose is to collect menstrual fluid (blood from uterine lining) and prevent its leaking onto clothes. The LSR Menstrual cups are usually made of flexible medical grade liquid silicone and produced by LSR Liquid Silicone Rubber Injection Molding and shaped like a bell with a stem. The stem is used for insertion and removal. The bell-shaped cup seals against the vaginal wall just below the cervix. Every 4–12 hours (depending on the amount of flow), the cup is removed, emptied, rinsed, and reinserted. After each period, the cup should be boiled for at least 5 minutes and stored for use the next month.

LSR Liquid Silicone Menstrual Cup Manufacturing Ways

Nowadays the LSR Menstrual Cup are mainly manufactured with FDA Medical Grade Liquid Silicone rubber, and produced by Liquid Silicone Injection Molding.

At earlier times, Menstrual Cups were mostly made by compression molding, while with the time going, people have higher requirements about quality and appearance, because for the menstrual cup made by compression molding, it is not so high transparency, and flashing & parting is big, which probably will effect the using experience.

Therefore, the designer & manufacturer choose to produce the period cup by liquid silicone injection molding. 

In this way, firstly, there will be minimum parting line, which is almost invisible, and also flashing will be quite small.

Secondly, mold life will be longer than compression mold, about 500Kpcs shots.

Thirdly, liquid silicone is Platinum Cured Silicone, which is safer than solid silicone. 

Fourthly, all these can provide a better user experience

LSR Liquid Silicone Menstrual Cup Pros  

1. Non-Toxic:

OrganiCups are made from 100% soft, medical-grade silicone. No BPA, latex or dyes. OrganiCup is also certified hypoallergenic. Heck-to-the-yes there won’t be any funky leaching chemicals!

2. Anti-Bacterial and Odor-Free:

Once you fold and insert your OrganiCup, it will unfold to form a light vacuum keeping it in place, so it won’t fall out! This vacuum seal ensures that your menstrual blood will not come into contact with air, making it hygienic and antibacterial, with no odor. No. Fishy. Business. Period.

3. No Dryness or Irritations:

Tampons absorb more than menstrual blood during your period; they also absorb other important vaginal secretions that keep you healthy. OrganiCup only collects, thus eliminating any irritation associated with dryness and ensures that the natural pH-balance is kept intact. Happy vagina dance, anyone?

LSR Liquid Silicone Menstrual Cup Cons

1. LSR Liquid Silicone Menstrual Cup can cause irritation, It’s important to wash your hands before inserting your cup, to clean it well between uses, and to empty it two to three times a day.

2. LSR Liquid Silicone Period Cup can be difficult to find the right fit. LSR Menstrual Cups come in different sizes depending on your age, flow, and whether you’ve had a child. Still, finding the perfect fit can be a challenge, more so if you have a tilted uterus or low cervix. It can take some trial and error, and you could have leaks in the meantime.

3. Removal can get messy -- or awkward. Even if you find it easy to insert the Liquid Silicone Menstrual Cup, removing it can be tricky. In a sit or squat, you need to use your pelvic floor muscles to push the cup down, then reach up and grab the stem. Pinch the base to break the seal and angle the cup slightly back to keep it from spilling.

4. If you’re in public, keep in mind you’ll need to wash out the cup in the restroom sink. (As an alternative, one manufacturer suggests bringing a bottle of water with you into the stall and rinsing it out, then wiping clean with toilet paper.)

5. It could interfere with an IUD. Some manufacturers don’t recommend using a menstrual cup if you have an intrauterine device (IUD) inserted, as there’s a chance the cup could pull on the string or dislodge it, but a 2012 study found no evidence of this. Still, it’s a good idea to talk to your doctor before combining the two.
