Dropper Cap Assembly Dropper inserts are suitable for rigid containers, including rigid plastic and glass dropper bottles. Since you can't squeeze glass containers, droppers are a popular alternative. However, essential oils can attack the rubber in the pipette.
This is where the essential oil dropper insert comes in. Dropper inserts are more than just an orifice for essential oils. Dropper inserts are designed with 4 (or more!) elements to provide a better user experience than orifice reducers for essential oils.
There are two main styles of dropper insertion: horizontal and vertical. Both inserts have a liquid outlet and an air inlet, and both share the common element of a better dispensing experience than a simple orifice reducer. You can learn more about the exact difference between horizontal and vertical dropper insertion in this article.
Once you've decided on your preferred style of dropper insert, you're ready to start filling. The components you need are: Dropper Insert, Dropper Bottle with 18 DIN Neck, and 18 DIN Dropper Cap.
Hats come in four styles. But, for the sake of discussion, let's use one of the most popular styles: the tamper-resistant cap.
Here are the steps to test the fit of the package:
Fill your bottle with essential oils or blends.
Start by inserting the dropper with the long tube into the bottle.
Press the top of the dropper insert so that it is flush with the rim of the bottle mouth. You will feel a little pop when the insert is attached to the bottle.
Unscrew the bottle's tamper-evident cap, which will seal the bottle so it's ready for the consumer.
Once consumers unscrew the cap, the tamper-evident seal is broken. However, the dropper insert will stay in the right place in every application.
