The filling capacity of the other design, the square-shaped Castor bottle, consists of 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 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.
STD and DIN18
STD is a DIN size, which 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 perfectly matched for the best performance. Basically, any 31.5 STD cap will fit any 31.5 STD bottle.
Some oil bottles are characterized by having a CPR neck finish. The corresponding caps have a built-in pouring spout, which makes them unsuitable for refilling bottles. However, the closure system makes it easy to reseal products, safely and hygienically. 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, 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.
