Throat spray pump, white, 18/410

Spray dispenser with an extended nozzle for 18/410 neck thread releases a small, measured dose from the bottle as a fine mist with each press. The long, narrow nozzle targets exactly where the product needs to land, which is why this type of closure is used primarily with oral sprays and breath fresheners, with liquid preparations for the lips or oral mucosa, and wherever a small amount of liquid needs to be applied to a precise spot without dispersing it into the surrounding area.

The dispenser is made from white polypropylene (PP), a lightweight and durable plastic. It fits small bottles and dropper bottles with an 18/410 neck, meaning products that customers carry with them and use multiple times a day. The packaging material is suitable for use with cosmetic products; a declaration of conformity is available with the product.

How the dispenser works

• Measured dose – each press always releases approximately the same amount, around 0.1 ml. The customer cannot overdose on the preparation, and the bottle's contents last for a predictable number of uses.
• Fine mist instead of a jet – the nozzle disperses the liquid into tiny droplets that spread evenly across the surface. A continuous jet would be uncomfortable on the mucosa and lips.
• Extended nozzle – compared to a standard sprayer, the nozzle is longer and narrower, allowing the dose to be directed into the oral cavity or a precisely chosen spot without affecting the surrounding area.
• Tube reaching the bottom – the dispenser draws the contents through a tube extending almost to the bottom of the bottle, so nearly all of the contents can be used.

Suitable formulations

The spray mechanism works reliably with liquids with a viscosity close to water: aqueous solutions, hydrolates, alcohol and hydroalcoholic extracts, tinctures diluted to application concentration, and solutions with a lower proportion of glycerin. The thicker the formulation, the worse it sprays. At a syrupy consistency, the dose becomes drops or a jet and the nozzle may clog.

Pure vegetable oils are not suitable for this type of dispenser, as they cannot be atomised into a mist and leave residue on the nozzle. If the formulation contains a higher proportion of essential oils or solvents, we recommend testing the behaviour of the plastic and seals with the specific contents before a larger production run.

Use in production

• Bottle selection – the dispenser fits 18/410 necks. The dropper bottles and flasks in the Handymade range share the same neck type and the combinations have been verified. For a custom combination, we recommend checking the seal, dosing, and packaging behaviour with the specific formulation.
• Shortening the tube – the tube is supplied at a length for taller bottles. For a shorter bottle, cut it with a sharp knife or scissors so that its end sits just above the bottom. An angled cut prevents the tube from suctioning to the bottom and stopping intake.
• Filling – fill the bottle to the nominal volume, not to the brim. The headspace below the neck is needed for the tube and the body of the dispenser, which displace some of the contents upward when screwed in.
• Tightening – tighten the thread by hand, without force. The PP thread can deform if overtightened and will no longer seal.

Good to know

Before first filling, we recommend rinsing the dispenser with clean water or ethanol and allowing it to dry completely. The inside of the mechanism is rinsed by pressing it several times in the clean liquid. The same procedure applies when reusing it. However, the internal mechanism cannot be disassembled, so the dispenser is better suited to repeated filling with the same type of preparation than to alternating different fragrances.

The mist from the nozzle reaches the mucosa directly, so the bottle's contents should be reliably preserved and the dispenser should be clean when filling. Aqueous formulations without a preservative do not belong in this type of packaging, regardless of how tightly it seals.

Polypropylene is a recyclable plastic. Before disposal, simply empty and rinse the dispenser.
