28 mm PCO Closures for bottled Drinking Water
I'm working at a water bottling company in Maldives. Recently, we have changed our bottle cap from 27 mm. Alaska cap to 28 mm. PCO caps.
But came to know that there are two types of 28 mm. PCO caps called 28 mm. PCO 1810 and 28 mm. PCO 1881 depending on the neck finish of the bottle. Can anyone help me to get the drawings of the two different types of caps ?
Attached are two reference drawings for the closures (sorry, couldn't find for the caps themselves). If I recall correctly, the primary differences in the 1810 vs. 1881 is that the 1881 is a lower form factor, being 4mm shorter from neck to top. This results in a slightly shorter thread pitch and turn.
Your supplier should be able to provide you with documents and recommendations for the correct product to use, though - best bet is nearly always to get data direct from the same place you're getting the caps/bottles. :)

Thanks Shaind.
Nice! I was looking for these drawings too. Very cool to be able to find them.
