Plastic bottle, clear round, white ribbed pump, 28/410, 500 ml

Plastic bottle with pump 500 ml – dispensing liquid and cream products

A ready-to-use set for repeated dispensing of liquid soaps, shower gels, shampoos, conditioners, body lotions, lighter creams or massage oils directly from the packaging. It consists of a clear plastic bottle with a nominal volume of 500 ml and a white dispensing pump with a knurled collar, both parts with the same neck type 28/410. The transparent wall allows you to see the colour, consistency and remaining contents, which customers appreciate with products whose appearance is part of their character.

The set as a whole is declared as suitable for contact with cosmetics. The food-contact certification applies to the bottle individually; the pump does not hold it, so the set as a whole is intended for cosmetic products.

Why choose this set

• Dispensing without contact with the contents – the pump delivers approximately 1 ml of product per press, so the contents are not contaminated by fingers or the area around the neck. For products with a water phase, this reduces the load on the preservative system.
• Volume for everyday rinse-off products – 500 ml is a practical size for shower gel, shampoo or liquid soap at the washbasin or in the shower, where the product is used up quickly.
• Lightweight and unbreakable packaging – plastic is light and can withstand a drop in the bathroom, which is a significant advantage over glass in a wet environment.
• Knurled pump collar – the ridged edge gives a better grip with a wet hand when tightening or unscrewing, for example when refilling.
• Proven combination – the bottle and pump share the same neck type, so there is no need to worry about finding a compatible closure.

Use and filling

The set is suitable for products with a liquid to medium-thick consistency that the pump can draw up through the dip tube and dispense. Surfactant products, low-viscosity lotions, oils and oil blends without solid particles work well. Thick creams, butters or products with exfoliating particles dispense poorly or not at all through a pump; for these, a jar or pot is more appropriate.

The bottle is filled to the nominal volume, not to the brim. The nominal volume is the quantity for which the packaging is designed under normal filling conditions. The total capacity up to the neck is greater, and the difference provides headspace for the dip tube and pump body, which push some of the contents upwards when screwed on, and for expansion of the contents with temperature changes. If the bottle is filled to the brim, the contents will overflow when the pump is attached.

Before first filling, we recommend rinsing both the bottle and the pump, disinfecting with isopropyl alcohol or ethanol, and allowing them to dry completely. Before fitting the pump, flush it several times with clean water and dry it out, so that no manufacturing residue remains in the mechanism.

Good to know

Clear plastic does not protect the contents from light. For products with sensitive ingredients, such as those with a higher proportion of unsaturated oils, essential oils or light-sensitive actives, a dark container or storage away from direct sunlight is more appropriate. For standard rinse-off products with a short shelf life in use, this is usually not an issue.

Plastic may react with concentrated essential oils and solvents. For products with a higher proportion of essential oils, alcohol or strong fragrance compositions, it is advisable to check after a few weeks whether any cloudiness of the wall, change in scent or softening of the material occurs. For standard emulsions and surfactant products with typical fragrance loading, such changes are not expected.

With your own formulation, we always recommend performing a test in the finished packaging: fill it, leave it for several weeks at room temperature and monitor whether the product dispenses smoothly, whether the pump gets stuck due to dried residue at the nozzle, and whether the appearance of the contents or the wall changes. The packaging is reusable; always wash and disinfect it when refilling, otherwise residues of the old product in the dip tube would contaminate the new fill. Ready combinations with other closures and individual closures with the same neck type are available in the Handymade range.
