Plastic trigger sprayer, 24/410, white, smooth collar

A lever sprayer with a 24/410 thread is a bottle closure that, when the lever is pressed, disperses thin liquid contents onto the skin, hair, or a surface. It is best suited for formulations applied in larger amounts and repeatedly: hair tonics, body sprays, hydrolats, and household cleaning products.

The sprayer body is made of polypropylene (PP), a lightweight and shatter-resistant plastic. The white version with a smooth collar suits both white and clear bottles. The sprayer is suitable for contact with cosmetic products; a declaration of conformity is available with the product.

Suitable formulations

The lever mechanism works best with thin liquids that behave similarly to water. The thicker the contents, the worse they spray and the more force is needed to press the lever.

• Hair care – hair tonics, leave-in detangling sprays, salt sprays, and styling products where even coverage along the full length of the hair is needed.
• Body and face sprays – hydrolats, body mists, and refreshing waters applied over a larger area.
• Household – surface, window, and bathroom cleaners, fabric and air fresheners, ironing water.
• Plants and workshop – misting plants and technical applications where a plain water-based solution is sufficient.

The dose per press is listed in the product parameters. It helps estimate how many pumps are needed per application and how long the fill will last.

Fitting onto the bottle and adjusting the dip tube

The sprayer is supplied with a long dip tube that is cut to length to match the height of the specific bottle. The tube should reach just above the bottom. If it is too long, it will bend inside the bottle and prevent the sprayer from being screwed on properly. If it is too short, the remaining contents cannot be dispensed.

After fitting onto a filled bottle, press the lever several times dry until the mechanism fills with liquid. Only then will the sprayer dispense evenly.

Fill the bottle to its nominal volume, not to the brim. The nominal volume is the volume the bottle is designed for under normal filling conditions. The total capacity to the brim is the physical volume right up to the neck. The difference between the two is a reserve for the sprayer mechanism with its dip tube and for the expansion of the contents with temperature changes. Overfilling the bottle will cause it to overflow when fitting the closure.

Good to know

• Preparation before first use – flush the sprayer by pumping clean water through it, then pump isopropyl alcohol or 70% ethanol through it and leave to air-dry. This also disinfects the inside of the mechanism and the dip tube, which cannot otherwise be reached.
• Solid particles and turbidity – undissolved powders, clays, glitter, and plant debris clog the nozzle. Filter infusions and macerated contents before filling.
• Changing the fill – pump warm water through the mechanism to remove any residue from the previous contents, then disinfect it again.

Bottles for the sprayer

The sprayer fits bottles with a 24/410 neck. The neck type is listed in the parameters of each bottle. Bottles with this neck as well as ready-made bottle-and-sprayer combinations are available from Handymade. For your own combination, we recommend testing the seal and output with your specific formulation.
