caps, pumps and bottles

24/410 and 28/410 have the most options of any neck here. A 24/410 cap can be a flip-top, screw, disc-top or child-resistant closure. The 24/410 lotion pump gives 2 cc or 4 cc a stroke, and the fine mist sprayer also comes in 24/410. Matching bottles: white HDPE and clear PET. Want the bottle and pump together?

Working to DIN/ISO?

European buyers often work to DIN/ISO neck designations rather than the 24/410 style. Tell us which system you use and we’ll quote in that system.

Not sized by a 410-series code

Airless pumps. An airless pump does not screw onto a standard bottle neck. It is sized by capacity and body diameter, and quoted as a system with its own bottle. See airless pump →

Cream jars. A cream jar lid is not sized by a 410-series neck code; it is sized on the jar diameter — our PP cosmetic jar, for instance, is 58 mm. Send us the jar and we’ll quote the jar and lid together. See bottles & jars →

    Questions

    What does 24/410 mean on a bottle cap?

    A 24 mm neck with a 410 thread. The first number is the diameter across the thread in millimeters; the second is the thread style. At Aman Pack, 24/410 takes flip-top, screw, disc-top and child-resistant caps, the 24/410 lotion pump, the fine mist sprayer, and HDPE and PET bottles.

    How do I find my bottle’s neck finish?

    Send us a photo of the bottle neck and we’ll identify it for you — you do not need to know the code. If you want to check it yourself, a neck size is two numbers: the diameter across the thread in millimeters, then the thread style, as in 24/410.

    Which caps fit a 28/410 bottle?

    Flip-top, screw and disc-top caps all come in 28/410. The same neck also takes our lotion pump, foam pump, fine mist sprayer and 28/410 trigger sprayer, and our HDPE bottle comes in 28/410, in natural. Tell us the pairing you want and we’ll confirm it in writing.

    Do you quote in DIN/ISO neck sizes?

    Yes. Many European buyers work to DIN/ISO neck designations rather than the 24/410 style. Tell us which system you use and we’ll quote in that system. If you are not sure what your current neck is, send a photo of it and we’ll identify it for you.

    Can I get the bottle and the cap from you together?

    Yes. Our bottles are blown in our own factory in Berrechid, Morocco, and supplied together with the caps that close them. Our HDPE bottle comes in 24/410, 28/410, 28/400 and 38/400; 24/410 and 28/410 are the same necks as our flip-top, screw and disc-top caps. Tell us the pairing you want and we’ll confirm it in writing.
