We developed the cosmetic bottle series to offer a design that makes your cosmetic or skincare brand stand out. Its unique, elegant and luxurious shape is available with rounded or squared shoulders that fit perfectly with the cosmetic jars series. The shape offers a large label area for your branding, and is available in 15 to 200 ml. The series fits perfectly with a wide selection of pump caps, spray caps and pipette droppers, with a neck finish for a 18/415 or a 24/410 thread.
Let’s talk about threads
...But what exactly are threads?
Simply put, threads are the protruding lines around the neck of the bottle. They ensure that the matching closure will have a tight fit to protect your natural products from being tampered with or from leakage. The thread size depends on the size of the bottle neck as well as our closures. Our bottles and jars and corresponding closures must have matching threads. If in doubt, it’s always advisable to contact our sales department.
GPI and GCMI
GPI and GCMI are the US norm for neck finishes and are followed by two numbers written like this: 22/400*. The first number indicates the neck finish diameter and is measured across the outside of the bottle’s threads. The second number refers to the height and thread style. Meaning the number of thread turns around the neck. Simply match the GPI or GCMI code listed in the product description to purchase the correct corresponding items.
* Please note that if a bottle has an additional ring on the neck, this may affect the choice of matching closure. For more details, please get in touch with your MIRON representative.
At MIRON Violetglass we ensure that our closures always fit the corresponding bottles and jars. However, sometimes it can be a bit of a challenge to find the right glass packaging to fit the needs of your natural ingredients. We are always happy to answer any questions you may have, and to become part of your product journey.
