Plastic bottle, clear round, white fine mist sprayer, 28/410, 500 ml

The ready-to-use set of a transparent plastic bottle 500 ml with a white lever sprayer 28/410 distributes liquid contents evenly over a larger area with a single press of the lever. Through the clear rounded plastic you can see how much fill remains, and the bottle is light even when full, making it comfortable to work with one hand. The set is designed primarily for water-based and alcohol-based solutions: surface cleaning and disinfecting products, hair waters and refreshing sprays in larger packaging, plant misting solutions, or alcohol for spraying the surface of cold-process soap.

Both the bottle and sprayer are declared suitable for contact with cosmetic products; the declaration of conformity is available with the product. The bottle alone holds a food-contact certificate; the sprayer does not, so the set as a whole is intended for cosmetic and technical use.

Key benefits

• Larger dose per press – the lever releases approximately 0.75 ml of liquid at once, speeding up work on larger surfaces.
• Dip tube reaches the bottom – the contents can be emptied with almost no residue, even when the bottle is held at a slight angle.
• Transparent contents – the fill level is visible at a glance, making it easy to monitor consumption and refill.
• Lightweight plastic – compared to glass, the bottle is lighter and more resistant to breakage if dropped in a workshop or bathroom.
• Complete set – the bottle and sprayer share the same 28/410 thread, so there is no need to check closure compatibility.

What the set is suitable for

The sprayer is designed for liquids with low viscosity. It handles water, hydrolats, tonics, hair waters, diluted alcohol, solutions with cleansing surfactants, and water-based plant preparations without issue. Thick emulsions, gels, oils, and anything with undissolved particles will slow down or clog the dispensing mechanism; for such contents, choose a different type of closure. Solutions that settle over time should be shaken before use.

Clear plastic does not protect the contents from light. Products containing essential oils, plant extracts, or other light-sensitive ingredients should be stored in a dark place or packaged in amber or blue containers. For more concentrated solutions containing essential oils or solvents, verify the behaviour of the plastic with the specific formulation to ensure there is no change to the surface or seal integrity.

Nominal and total volume

Nominal volume of 500 ml is the volume the bottle is designed for during normal filling. The total volume to the rim of the neck is physically larger. The difference provides headspace for the sprayer's dip tube, which displaces liquid upward when inserted, and for liquid expansion due to temperature changes. Fill only to the nominal volume, not to the rim; otherwise, liquid will overflow when the sprayer is screwed on.

Good to know

Before the first fill, wash and disinfect both the bottle and sprayer with isopropyl alcohol or ethanol and allow to dry completely. For the sprayer, also rinse the tube and nozzle to ensure no water from washing remains inside. The set is reusable. When changing contents, always flush the mechanism with a few pumps of clean water so that residue from the previous fill does not clog the nozzle.

Tighten the sprayer evenly when screwing it on, without cross-threading. If the lever does not draw up liquid after the first fill, press it several times without liquid until the dip tube is primed. Use the smooth cylindrical section of the bottle for labelling.

When empty, the bottle belongs in sorted plastic waste. Unscrew the sprayer before disposal, as it is a composite mechanism made of multiple parts.
