Product description

The black plastic cap is a replacement or additional closure for a 5 ml roll-on bottle. It covers the ball insert and protects it from dust and dirt. It also prevents the ball from rolling freely and releasing the contents when carried in a bag or cosmetic pouch.

The black colour is neutral, so the cap suits bottles of various colours. It also comes in handy when the original cap has been lost or damaged but the bottle and ball insert are still in good condition.

What the cap is suitable for

Oil perfumes and fragrance blends – the cap covers the ball, which touches the skin with every application.
Aromatherapy roll-ons – diluted essential oils in a carrier oil are often carried around, so it is important that the ball does not roll freely inside a bag.
Eye area serums and targeted treatments – a covered ball stays clean, which matters for products applied near the eyes.
Liquid lip balms and cuticle oils – small travel-size packaging opened and closed many times a day.

Good to know

The cap is suitable for contact with cosmetic products. The relevant declaration is stated in the product parameters.

Before first use, we recommend washing the cap, disinfecting it with isopropyl alcohol or ethanol and allowing it to dry completely. Any remaining moisture inside the cap would transfer to the ball upon closing, and from there into the contents.

A filled roll-on should be stored upright. This way the contents remain in prolonged contact with neither the ball nor the cap, reducing the risk of oil accumulating beneath the cap.

The bottle is filled to its nominal volume, meaning the volume the container is designed for under standard filling conditions. The total brim volume is the physical capacity up to the neck. The difference between the two is a reserve for the ball insert and for expansion of the contents with temperature changes.

Concentrated essential oils and solvents can affect plastics. For blends with a high proportion of essential oils, we recommend testing the cap's behaviour with the specific formulation.

Bottles and other closures with the same neck type, as well as ready-made combinations, are available from Handymade. Cap dimensions are listed in the parameters. When combining with a bottle from another source, we recommend verifying in advance that the cap seats correctly and the assembly seals. Once no longer usable, the cap belongs in sorted plastic waste.

Frequently asked questions

Which bottle does the black cap for a 5 ml roll-on fit?

The cap is intended for the 5 ml roll-on bottle with a ball insert from the Handymade range. With bottles from other suppliers, the neck and the height of the ball insert may differ. It is therefore necessary to compare the dimensions stated in the parameters and verify the seal on a filled bottle.

Will the roll-on cap prevent the contents from leaking?

The roll-on cap reduces the risk of leakage by preventing the ball from rolling, but the seal depends on the entire assembly. The correct fit of the ball insert, the viscosity of the contents, and the fill level all play a role. Thin oils and alcohol-based blends should be tested on a single filled bottle laid on its side before filling a whole batch.

Can the roll-on cap be reused?

Yes, an undamaged roll-on cap can be reused. Before the next use, wash it with warm water and detergent, sanitise with isopropyl alcohol or ethanol, and allow it to dry completely. If the cap is cracked, deformed, or no longer sits firmly on the neck, it is better to replace it, as it may no longer protect the ball reliably.

Is the plastic roll-on cap suitable for blends with essential oils?

Yes, for standard diluted blends of essential oils in a carrier oil, the plastic roll-on cap is suitable. When stored upright, it is not in permanent contact with the contents. Concentrated essential oils can degrade plastics over time, so for blends with a high proportion of essential oils it is advisable to inspect the cap after several weeks of storage.

Why is the 5 ml roll-on bottle not filled to the brim?

The roll-on bottle is filled only to the nominal volume because the space below the neck is a reserve for the ball insert. When filled to the brim, the insert displaces some of the contents upon insertion. This overflow runs down the bottle and collects beneath the cap. The reserve also compensates for expansion of the contents at higher temperatures.
