Buyer guide
How do you match a pump, CTC, dual-seal or spout cap to a bottle neck?
Choose the closure by what it has to do (pump or spray the product, pour it, or seal it against leaks), then match it to the bottle by the neck size in mm and the thread style. A closure that fits the diameter can still fail on the thread, so quote the neck code from the bottle drawing, or send a sample. How to read a neck finish code.

Start with what the closure has to do
Closures do one of three jobs. Pumps, sprays and spout caps dispense: they meter the product or direct its flow. Fliptop, disctop and push-pull caps open and close without unscrewing, usually with a set orifice. Dual-seal and liner-fitted screw caps seal, for products that must not leak in transit.
Pick the job from your product. A thin liquid suits a spray or a small orifice; a thick sauce or paste needs a wider opening. Pumps and sprays also have to suit the bottle's bore, so decide the closure before you finalise the bottle, or send the bottle and ask for a match.

What the types mean in practice
- Pumps: lotion, serum and beak-style pumps press product out through a dip tube, so they depend on the neck and on the tube reaching the bottom of the bottle.
- Sprays: mist pumps and trigger sprays atomise or spray a liquid; trigger sprays are the larger format, for household-style bottles.
- CTC caps: listed by neck size and as single-piece or two-piece (the two-piece has a separate liner). Closure names are trade shorthand, so confirm what you mean with a drawing or a sample.
- Dual-seal caps: a screw cap with an integrated liner, described in the catalogue for leak-critical fills.
- Fliptop, disctop and push-pull caps: open by hinge, press or pull; fliptops are listed with their orifice where it matters.
- Spout caps: listed by orifice size for the small ones and by neck size for the 42 mm ones, so read which number a row gives before you compare.
Matching the closure to the neck
Two things must agree: the diameter in mm and the thread style. A closure and a bottle that are both “24 mm” can still not fit if the thread differs, which is why a full finish code such as 24-410 is what to quote. The neck finish guide explains how the codes read.
For pumps and sprays, also give the bore of the neck and the height of the bottle, because the dip tube has to pass the bore and reach near the base. For fliptop and spout closures, a row may give both a neck size and an orifice: the neck decides whether it fits, the orifice decides how fast the product flows.
If the closure goes on food, say so in the enquiry, along with any documentation your market requires, and which liner or wad the cap should carry. Compatibility between a liner and the product (oils, alcohol, acids) is worth testing on your own filling line.
What to send for an FOB or CIF quote
- The closure type and the size from the catalogue row, or a drawing or a sample if the closure is not listed.
- The bottle's neck code and bore, and its height if it takes a pump or spray.
- The product it will carry (thin liquid, sauce, cream, alcohol), and the colour you want.
- Quantity, destination port, and whether you want FOB or CIF.
The reply gives FOB or CIF pricing, the minimum order quantity and the lead time, usually within two working days. Which of FOB or CIF to ask for.
