CR Dropper Cap

Suitable for glass dropper bottles featuring an 18mm-415 neck finish, as well as Boston Round Bottles with a GPI 400 neck finish.

We offer two design options: the CR cap (Child Resistance dropper cap) and a standard design with a tamper-evidence ring for dropper bottles with an 18mm-415 neck finish. Additionally, we provide both CR cap and standard design options for Boston Round Bottles with a GPI 400 neck finish.

The 18mm-415 neck finish, also known as GL18 or JY18, is the widely accepted standard for glass dropper bottles, designed to regulate the dispensing of medicines and essential oil products. It features typical dimensions, including an inner diameter of 10.65mm, an outer screw diameter of 17.75mm, and a skirt diameter of 20mm.

Our GPI 400 neck finish options encompass 18mm-400, 20mm, 22mm, 24mm, and 28mm sizes.

You have the flexibility to choose from a variety of shapes and styles, and the length of the glass pipette can be adjusted to match the inner height of the bottles to your preference.
