Continuous Spray Bottles: Pre-Compression, and Why They Cost Ten Times a Trigger
By Joe Joo · 8PCK · Shantou · Updated 26 October 2026
A continuous spray bottle holds pressure and delivers a fine, steady mist for a full second. It is the most expensive closure in the catalogue, and the reason is the pump.
A continuous sprayer pressurises the liquid with a few pumps, then releases a steady mist for about a second. No propellant, no aerosol can — just a different pump.
The free Bottle Spec Checker tests whether your neck fits the closure and whether the wall survives a pump stroke.

How It Works
Pumping charges a small chamber; pressing the nozzle releases the stored pressure through a fine orifice. The spray is even because the pressure is, not because the pump is.
Pre-Compression
The chamber fills to a set pressure before it releases; that is what makes the mist even.
Non-Aerosol
No propellant gas, so no aerosol regulations.
Why It Costs So Much
The valve and chamber are precision parts; the assembly is slower and the reject rate is higher. A continuous sprayer can cost several times a standard trigger.
Where It Pays
Sun care, hair styling, cleaning products where even coverage matters. Not for a product that is poured or pumped.
Questions We Get on This
What is a continuous spray bottle?
A bottle with a pre-compression pump that delivers a steady mist for about a second per press.
Is it an aerosol?
No — it uses a mechanical pump, not a propellant gas.
What is the MOQ?
3,000 pcs typically, because the valve assembly is volume-based.
What sizes?
200–300 ml is the common range.
