Product: Menstrual Cup

Onpery Store

• • • 

A Menstrual Cup is to be inserted through the vulva and placed in the vagina, to collect menstrual fluid. It is made of medical-grade silicone. Once the user gets comfortable with the insertion and removal process, then it is perhaps the most economical, eco-friendly and comfortable menstrual product to use.

As menstrual cups are internal products, and as no two vaginas are the same, it is not possible that one design would be suitable for all. There are numerous factors other than design, like hardness, thickness, size, proportion, etc. of the cup which may suit one but not the other. With the novel design of Onpery® Menstrual Cup, we have tried to make the product suitable for the majority of the users.

Variants and Sizes


Size - Small:
• Low cervix height
• Low flow

The Size Mini can also be used by menstruator who have fear of insertion, but it may be suggested to adopt the Size Regular once comfortable with Size Mini.

Size - Medium:
• Low to average cervix height
• Low to average flow

Size - Large:
• High cervix height
• Heavy flow


Novel Design Details:

(1) Easier Insertion:
Novel curved top-rim
= Smaller top-rim area, compared to a generic cup
= Gradual insertion

The top rim has a curved slant which ensures that the fold of the cup is small enough to aid ease during insertion. This makes the process smooth even for menstruators with smaller vaginal openings.

(2) Cervix-friendly:
Novel curved top-rim
= Ergonomic as per the angle between cervix & vagina

The cup does not hit the cervix due to the curved inclination in the top-rim which is designed to sit comfortably in the vaginal canal. This feature makes it ideal for menstruators who have an average to low cervix.

(3) Easier Removal:
Novel flat faces at front & back
= Instant breaking of suction
= Firmer grip

The flat faces at front and back makes sure that the vacuum seal is broken even when light pressure is applied to it. It also provides a better grip on the cup during the process of removal.

(4) Spill Resistant:
Novel ribs and larger height at back
= Resist spillage while removal

The back of the cup has ribs and the height is higher than the front, which prevents spillage during the process of removal.


(5) Intuitive:

Novel asymmetric design
= Semantical

Overall semantics of the menstrual cup helps the user build confidence by making them aware of how to interact with the cup, especially for first-time users. If the user needs to reduce the height of the cup, then a step has been given at the stem to guide users on where to cut.


Generic Value:
• Reusable for up to 5 years.
• Up to 12 hours wear-time. Longer and care-free outdoor travel.
• Collects blood, hence dry.
• Swim-friendly. Sport-friendly.
• Decomposable. (Converts into ash.)

• Highly economical.

Use case

A Menstrual Cup is a viable option for women in their mid-teens right up to menopause.

Not to be used, if:
• A menstruator is using Copper-T.
• Post delivery of a baby, for about a year. Consult your doctor on this.

For first time users:
We suggest that you relax before trying out the cup. Maybe take a few deep breaths. This exercise helps your vaginal muscles relax. Do not try insertion in a tense state of mind. The best preferable time to use a cup is when your vagina is lubricated. Users can try using water to make the process smooth and irritation-free. 

The journey can be daunting for a first-time user, but if you try consistently, you’ll be comfortable with the product in about two menstrual cycles.

Learning Curve:
The usual duration of the learning curve with Onpery® Cup (although it can vary):
• First-time adopters of Cup can need up to 2 months to get used to the process of insertion and usage in general.
• Prior Cup users will find it very easy to switch to Onpery® cup within the first cycle.

How to Use

Types of the fold:

We realize that everyone has a different body and therefore you might need to try different cup folds before finding the one that works the best with your anatomy. Here are a few folds you can try practicing:

a. U-Fold:
A common and popular method to fold the cup is the U-fold. Hold the cup with both hands and fold it in such a way that both of your thumbs meet. Now push the cup to flatten it so that it creates the U shape.

b. Punch Down Fold:
The punch-down fold is ideal for first-time users and those who have a smaller vaginal opening. Hold the taller side of the cup at the base with both of your hands. Place the index finger of your dominant hand to push the top part down inside. Now use your non-dominant hand to bring the sides together. Remove your index finger and use your dominant hand to hold the cup firmly.

Usage Steps:

Step 1: Cleaning

a. Sterilize:
Boil the cup in water for 3-5 minutes before the start of your menstrual cycle. Use a steel container and boil some water. Put the cup in a downward position such that the cup floats. This process will result in minimum or no contact between the cup and the container. You could also use a menstrual cup sterilizer available in the market. Sterilize your cup before and after your menstrual cycle, not between your period.


b. Wash:
Wash your hands with soap before inserting the cup into the vagina. Avoid using harsh soaps and wash the cup with regular water. Using soap on your cup can increase the chances of unnoticed residue or change the pH balance of your vagina.

Step 2: Insertion

c. Fold:
While there are many folds a transitioning user could try, our research recommends trying the punch-down fold for a first-time user. Try practicing each fold before starting the process of insertion.


d. Posture:
Spread your legs apart and slightly bend over so that you have space to work. Some people find it comfortable to keep one leg on the toilet seat. You could also try squatting. Feel free to try different postures to figure out what works best for you.

e. Insert:
During insertion, ensure that the long side of the cup is toward the back of the vaginal wall. The cup and the stem should be comfortably inside your vagina.

f. Position:
Once the cup has been inserted in the vagina, use very little pressure to pinch at the bottom of the cup and twist it slightly or rotate your finger around the cup. This act will ensure that the cup has popped up and formed a seal inside your vagina.

Step 3: Usage

g. Usage:
Let your cup collect the blood for up to 12 hours and carry on with your day or sleep comfortably. The wear duration will vary depending on the amount of menstrual flow of the menstruator with respect to the day of their menstrual cycle, but in any case, it should not be worn beyond 12 hours.

Step 4: Removal

h. Posture:
Spread your legs apart and slightly bend over so that you have space to work. Some people find it comfortable to keep one leg on the toilet seat. You could also try squatting. Feel free to try different postures to find out what works best for you.

i. Remove:
Wash your hands with soap before removing the cup from the vagina. Whenever you feel like emptying the blood, remove the cup by spreading your legs or squatting. Pinch the cup at the front and back flat sides such that the seal breaks and then slowly go on to pull out the cup.

Step 5: Re-insert

j. Wash:
Empty the contents of the cup and wash it with plain water. We do not recommend using harsh soaps or liquids to rinse the cup. You do not need to sterilize the cup; washing it with water between removal and insertion when you're on your period is enough. Sterilize your cup before and after the end of your menstrual cycle only. Re-insert the cup till your menstrual cycle is not over.

Step 6: Storage

k. Pouch:
After the end of your cycle, sterilize the cup and allow it to dry completely before storing it in the pouch.

Ways and When to Discard

A user can dump the product into a medical waste bin near a medical clinic or similar place from where the menstrual cup can go into an incinerator and get converted into ash.

You can also burn your silicone menstrual cup to ash. Medical grade silicone is derived from silica, which is found in sand. Silicone is made through a chemical process but from natural materials, so the ash left behind isn’t harmful to the environment.

How to know if the Cup is not ideal for use anymore:
• If there is any scratch or cut on the surface of the Cup.
• If the Cup has deformed due to coming in contact with a hot surface.

The silicone (if 100% pure) by nature changes its colour if kept in an open space. If the Onpery® Menstrual Cup changes its colour after a few months due to natural reasons, then there is nothing to be worried about. In case of any concern please contact a doctor.

Q1. Can I lose my virginity if I use a cup?
No. Virginity is only lost if one participates in sexual intercourse. Sexuality is a wide spectrum and it depends on what is considered to be intercourse. But speaking biologically, hymen is a thin piece of tissue that fully or partially covers the vagina, insertion/removal of the cup may break the hymen, but so can activities like playing sports or cycling. In fact, there are some people who are born without a hymen. Using a cup has got nothing to do with virginity.

Q2. Can the cup get lost inside my body?
No. The cup enters a cavity-like structure inside your body. The cervix lies at the other end of it. Nothing can escape or pass through that.

Q3. Does it hurt once the cup is inside?
Menstrual cups are not supposed to hurt. Measuring the cervix can help you understand the length of your cervix. If a cup is causing discomfort, chances are that it is hitting the wall of your cervix. The Onpery cup is designed for menstruators with an average to low cervix. Its ergonomic shape ensures that the cup does not hit your cervix.

Q4. Will I have to remove my cup every single time I pee?
Removing the cup when peeing is not something to worry about. Urine escapes your body through the urethra which is a completely different orifice. The cup cannot block or collect urine.

Q5. Will the cup stretch my vagina?
The vagina is a wonderful organ and one can compare it to a rubber band. It will slightly spread when the cup is placed but it will come back to its original position once the cup is removed. Using a menstrual cup will not affect the size of the vagina.

Q6. Will the usage of menstrual cups cause infections?
Using a certified and medical grade menstrual cup will not cause infections, if sterilized efficiently after each cycle. If there is any difficulty or pain in usage of the cup then medical attention should be sought.

Q7. What if the cup gets full and I forget about it?
A simple way of tackling this in the initial days is to set a timer. The nature of menstrual cycles vary from person to person. For normal to heavy flow, make sure the cup is  removed and reinserted to get an idea of the flow. A cup can normally be used anywhere between 8 to 10 hours on a stretch.

Q8. Does it hurt once the cup is inside?
Menstrual cups are not supposed to hurt however if you experience discomfort, consult a gynaecologist. You cannot physically feel anything after the initial days which makes it ideal for sports and activities such as swimming.

Q9. When should I consider buying a new cup?
We recommend replacing menstrual cups every 3-5 years. It should be replaced if it has any cuts, holes, scratches, deformation or just isn’t in a good condition anymore.

Q10. How do I discard my cup?
Dump it into a bin of bio-medical waste. Bins of hospital or clinic would be ideal, since the cup will be incinerated along with the medical waste generated there. You may also cut the menstrual cup and bury it into the ground and it will decompose in 50-500 years, depending on the conditions.

Q11. Should I be concerned if my cup turns yellowish?
Silicone changing its colour (mostly yellowish) with time is a natural property of the material and is not a cause for concern.

Q12. How do I store my cup?
When the cup is not being used, store it in a dry and clean breathable pouch. The pouch should then be kept in a closet or a drawer away from direct sunlight.

Q13. When should I start using a menstrual cup?
One can switch to a cup at any age provided they find their suitable cup size. Women who are using Copper-T or have given birth in the last 12 months should not use the cup.

Q14. When should I measure my cervix?
The best time to measure your cervix is when you’re on your period. This is because you require a cup that works for your entire cycle. Your cervix moves throughout your period and never stays in one fixed place. You could also do it right before you’re supposed to get your period or when you’re on the last day of your period.

Q15. How do I measure my cervix?
You’ll need to insert your index finger into your vagina to measure your cervix. Before you do this, wash your hands with soap and make sure your fingernails are short and filed so that you avoid scratching or injuring yourself.

Q16. What is my cervix supposed to feel like?
Your cervix is supposed to feel like the tip of your nose. You can measure if you have a high cervix, average cervix length, or a low cervix with the help of your index finger.
