Your pump is a mechanism, and a mechanism that unscrews itself becomes a returned product. The beauty and household trade settled on a taller neck than food uses for that reason, and 24-410 is the size most of your suppliers stock.
The Published Figures for a 24-410 Neck
| Symbol | Dimension | Figure |
|---|---|---|
| T | Diameter across the thread. | 23.67 mm plus or minus 0.20. |
| E | Diameter at the thread root. | 21.54 mm plus or minus 0.20. |
| I | Minimum bore. | 13.11 mm. |
| H | Finish height. | 16.41 mm. |
| S | Sealing surface to the first thread. | 1.17 mm. |
T minus E is your thread depth, a little over a millimetre on each side. Your pump collar engages that depth over one and a half turns, and that engagement keeps it from backing off when a consumer works it a hundred times.
A pump, a foamer and a sprayer each fix the neck, so the closure you already buy decides your bottle.
What Sits on a 24-410 Neck
Your lotion pumps first, then foamers, treatment pumps, trigger and fine-mist sprayers, and disc-top or flip-top caps for thicker products. All of them share the same collar, so a range can move between a pump on the 250 ml (8 oz) size and a disc top on the 60 ml (2 oz) size without a second finish.
SGSBOTTLE forms these necks in Shandong and at Xuzhou, on lines that also run the 18, 20 and 28 mm sizes. The bore limits the rest. At a minimum of 13.11 mm your neck passes a standard dip tube and most actuator stems, and it fills quickly enough for a viscous lotion. A thicker product, a scrub with particles or a balm needs a wider neck, and that moves you to 28-410 or into jars.
The 410 Sizes Around Your 24 mm Neck
| Finish | Typical formats | Typical closure |
|---|---|---|
| 18-410 | 15 to 50 ml (0.5 to 1.7 oz). | Small treatment pumps, dropper collars. |
| 20-410 | 30 to 100 ml (1 to 3.4 oz). | Serum pumps, mist sprayers. |
| 24-410 | 60 to 250 ml (2 to 8 oz). | Lotion pumps, foamers, disc tops. |
| 28-410 | 200 to 500 ml (7 to 17 oz). | Larger lotion pumps, trigger sprayers. |
The published heights climb with the diameter across the 410 series: 13.28 mm at 18 mm, 14.07 mm at 20 mm, 16.41 mm at 24 mm and 17.73 mm on the glass 28 mm drawing. Your pump supplier stocks a collar for each of them. SGSBOTTLE forms your soap and lotion glass on 14 lines in Shandong and Xuzhou, seven at each site.
Glass Against Plastic on the Same 410 Number
The 410 series is written for both, and the drawings differ by hundredths of a millimetre. Your pump made to the plastic chart usually runs on glass, and your tight-tolerance airless pump sometimes does not. Where your closure is a precision part, your supplier reads the glass drawing on the SGSBOTTLE quotation rather than the generic chart, and a sample settles it.
What Goes on Your Enquiry
The pump or sprayer you already buy, the format in ml and oz, the product and its viscosity, and the filling line. SGSBOTTLE engineers return the bottles whose finish drawing that closure fits, with the internal height for your dip tube, so the pump arrives cut to the bottle.
