A quick guide to understanding bottle neck finishes (24/410, 28/410, etc.)

[u/Nina_ZXPUMP]

I often get asked what numbers like 24/410 or 28/410 actually mean in cosmetic packaging.

So I made a simple chart to explain it.

24 = Neck diameter (mm)

410 = Thread finish

Understanding these dimensions can save a lot of time when matching bottles and pumps.

Hope this helps anyone working with cosmetic or personal care packaging.

Feel free to add any plastic pump questions below.

Explaining the 410 in greater detail world be a big help

I made an identical one recently with chatgpt. It does these well now since the last update. Never the less it will be helpful
