Two bottles with the same body can feel completely different because of the closure. The closure controls dose, texture and user ritual — so it deserves the same thought as the material. This guide matches dropper, lotion pump, mist spray and trigger to the formula and use, and explains the neck-finish rule that decides what actually fits.
Bottles from our catalogue — bottle bodies for dropper, pump and spray closures.
Dropper — controlled dose for oils and concentrates
A dropper suits high-value, low-volume products: facial oils, beard oil, serums and concentrates where a few drops matter. It reads premium and wastes little. It needs a compatible glass or plastic bulb and a matched neck (commonly 18/415 or 20/410).
Lotion pump — measured dose for creams and liquids
A lotion pump gives a consistent press of lotion, shampoo or conditioner. It needs a 24/410 or 28/410 neck and suits 100 ml and larger bottles. Output per stroke is configurable (e.g. 1-4 cc), which matters for dose-sensitive formulas.
Mist spray vs trigger — coverage vs power
A fine mist spray is right for toners, setting sprays and essences; a trigger sprayer delivers more volume for cleaners, disinfectants and hair mist at 500 ml+. Both need a matching neck finish, and both can clog with thick or particulate formulas.
The neck-finish rule
The closure only fits if diameter AND thread match (e.g. 28/410). A bottle, pump and cap in the same neck finish are interchangeable across suppliers, which de-risks your supply chain. We confirm neck finish at quotation so a pump sourced elsewhere still seats on our bottle.
Mistakes that cause leaks
Most leaks are a neck mismatch, not a bad pump. A 28/415 cap on a 28/410 bottle may look right but will not seal. Also watch actuator compatibility: a lotion pump rated for thin lotion will stall on a thick cream. Match both the neck and the viscosity rating.
Sourcing closures separately
You can buy bottles from us and closures from a specialist — as long as the neck finish matches exactly. We publish the neck finish for every bottle so your closure supplier can confirm fit before they ship. This is normal for brands optimising closure cost or function.

Frequently Asked Questions
How do I choose a closure for my bottle?
Match the neck finish first (e.g. 28/410), then pick the action: dropper for oils, lotion pump for creams, mist or trigger for sprays.
Can one bottle take different closures?
If the neck finish is identical (same diameter and thread), yes — a 28/410 bottle can take a pump, spray or cap interchangeably.
What does 24/410 mean?
24 mm neck diameter with a 410 thread standard — common on 100-200 ml treatment and lotion bottles.
Which closure best protects actives?
An airless pump gives the best oxygen protection; a dropper is fine for stable oils but exposes the formula to air each use.
Why does my pump not fit?
Almost always a neck mismatch (diameter or thread). Confirm both numbers before tooling the bottle or buying the closure.
Can I get a custom-output pump?
Yes — lotion pumps are configurable per stroke (typically 1-4 cc); tell us the target dose at quotation.
