Let’s talk about threads
...But what exactly are threads?
Simply put, threads are the protruding lines curved around the bottle neck. They ensure that the matching closure will have a tight fit to protect your natural ingredients from being tampered with or from leakage. The threads size depends on the size of the bottle neck as well as our range of closures. Our bottles and jars as well as the corresponding closures must have matching threads. If in doubt, it is always advisable to contact the sales department.
GPI and GCMI
GPI and GCMI are the US norm of 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 threads turns around the neck. Simply match the GPI or GCMI code listed in the product description to purchase the corresponding items.
* Please note that if a bottle has an additional ring in the neck, this may affect the choice of matching closure. For more details, please get in touch with your representative.
At MIRON Violetglass we ensure that our spare parts always fit the corresponding closures. However, it can sometimes be a bit of a challenge to find the right closure which complements the needs of your natural ingredients. We are always happy to answer any questions you may have and to become a part of your products journey.
