Vitamin Jars

The narrow wideneck jar series Carina has a chic and slender look. It is the narrowest series of the family, available in two sizes 50 ml (1 2/3-oz) and 100 ml (3 1/3-oz). Both narrow jars have the same diameter which means that they pair with the same lids. The standard wideneck jar series was the first series of wideneck jars designed by MIRON. It is the only wideneck jar series that has a lid that is not aligned with the body of the jar which gives it a nice retro and vintage effect. The extra wide wideneck jar series has a robust and strong look, available in two sizes 250 ml (8 ½-oz) and 400 ml (13 ½-oz). Both extra wide jars have the same diameter.

Let’s talk about threads

...But what exactly are threads?

Simply put, threads are the protruding lines curved around the neck of the bottle. 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 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 bottles threads. The second number refers to the height and thread style. Meaning the number of threads turns around the neck. Our Carina 200 ml features a 48/400 (1 thread turn) neck finish. The Carina series is often used for para pharma, and with its matching closure, it is also considered food safe.
* 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.

Special thread

A special thread differs from the standard threads on the market. This is because some MIRON products are tailored to unique (market) demands that differ from standard packaging shapes/sizes. This means that the choice of corresponding accessories is limited. On the bright side, we offer them all. The lids that fit these special threaded jars are designed to create the perfect fit. Simply match the diameter indicated in the product description with the corresponding Modern or Classic lids to purchase the related items.

At MIRON Violetglass we ensure that our closures always fit the corresponding bottles and jars. However, it can sometimes be a bit of a challenge to find the right glass packaging 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.
