40/410 Foam Pumps

What 40/410 means

40/410 is a wide foam-pump neck: 40 mm across the thread, 410 thread specification. It sits between the narrow 30/410 facial-foam neck and the 43/410 large-dispenser neck, and it is the size most 300–500 ml hand-soap and shower-gel bottles are moulded for.

Which dispensers use a 40/410 neck

• Hand soap — 300–500 ml pump bottles in bathrooms and kitchens.
• Shower gel — mid-size bottles where a 43 mm collar would crowd the shoulder.
• Foam cleanser — thicker gel bases converted to foam at the nozzle.
• Refillable dispensers — the pump is re-used across refill packs.

0.8 ml per stroke from the 601 series

The chamber is the same one used on the 43/410 version: 0.8 ml of foam per stroke, roughly double what a 0.4 ml facial foam pump delivers. That is the volume a hand-wash needs to feel generous — one stroke covers two hands without a second press.

40/410 versus 43/410 — pick by the bottle

These two look alike in a photo and are not interchangeable. 40/410 closes mid-size bodies; 43/410 spans the wider shoulder of 500 ml–1 L dispensers. The collar diameter and thread engagement differ, so the bottle decides the pump, not the other way round. If you are launching a new mould, tell us the neck drawing and we will confirm before tooling.

Foam density and your base

Lather quality is a function of both the pump and the liquid. The mesh configuration in the 601 generator is tuned for higher-viscosity bases so the foam stays dense at the end of the bottle rather than turning thin. Send us the base viscosity and surfactant system, and we will recommend the mesh before you commit to a bulk run.

Finish and decoration

Standard finish is pearl white. Custom colours are matched against a colour chip, with silk-screen and hot-stamp on collar and actuator. Matte finishes are available on selected moulds.

Ordering and samples

MOQ is 10,000 pcs per model and closure finish. Every unit passes an automatic functional test before packing, and stock samples are free for qualified projects.
