Our oil bottles series are mostly used to store high quality natural oils such as olive oil, seed oil, vegetal oil, essential oils. The MIRON glass oil bottle series comes in two different designs. The round shape Pollux comes in 100 ml, 250 ml and 500 ml and has a 29.4 CPR thread. The filling capacity of the square shaped Castor bottle varies between 100 ml, 250 ml, 500 ml and 1 L.
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.
STD and DIN18
STD is a DIN size. DIN is the industry standard for dropper bottles in Europe. However, the DIN determines the bottling standard for a variety of industries. The DIN size is the German-based norm; it refers to the standard size of the neck, height, and diameter. STD caps and bottle necks are matched for the best performance. This simplifies the souring of related products as any 31.5 STD cap will fit any 31.5 STD bottle.
Some oil bottles are characterized for having a CPR neck finish. The corresponding caps have a built-in pouring spout, which makes them unsuitable for refilling bottles. The closure system of this cap makes it easy to reseal a product and is characterized as being safe and hygienic —a perfect fit for premium olive oils and similar products.
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.
