Neck Finish Compatibility
The neck of the bottle and the cap must match precisely to ensure a proper seal. For example, DIN18 refers to the European industry standard often used for dropper bottles, where 18 denotes the diameter in millimetres. In the United States, the GPI/GCMI system is used. A common example is 22/400, where 22 refers to the neck diameter and 400 to the thread height and style.
Closure Types and Series
Calaso offers screw caps in a wide variety of models, including Series II, III and IIID. These are available alongside tamper-evident and child-resistant versions, depending on your functional and regulatory needs.
