Gloss Black Glass Bottle with Roll-On, 10 ml

Glass bottle, black glossy, roll-on, 10 ml

A roll-on set with everything needed to apply liquid preparations directly to the skin: a 10 ml glass bottle, a ball housing with a steel roller ball and a black cap with an 18/410 neck finish. The roller ball dispenses the contents in small amounts, without dripping and without fingers touching the filling. It is suitable especially for oil-based perfumes, blends of essential oils in a carrier oil, roll-ons for temples and wrists, spot serums and preparations for the eye area and lips.

Black glass does not let light through, so the contents are not exposed to light. This makes it suitable for light-sensitive fillings, especially blends with essential oils and vegetable oils. The glossy surface with the black cap looks uniform, which is useful for a series of products with the same appearance. The set is declared suitable for contact with cosmetic products. The certificate for direct contact with food applies only to the glass bottle on its own; the set as a whole is intended for cosmetics.

How to use a roll-on

The bottle is filled without the roller ball fitted. The ball housing with the roller ball is then pressed into the neck and the cap is screwed on, protecting the contents from drying out and preventing the bottle from opening accidentally in a bag. During application the roller ball turns and transfers a thin layer of the preparation to the skin. The amount applied depends on the number of strokes.

The roller ball works with liquid and thin-flowing contents. Oils, oil-based perfumes, blends with alcohol and light serums are dispensed through it without difficulty. Thicker gels and creams are not spread evenly by the roller ball and may block it. This type of closure is not intended for them.

Nominal volume and total volume

The nominal volume of 10 ml is the amount the packaging is designed for under normal filling. The total brimful volume given in the parameters is the physical volume of the glass up to the neck. The difference between them is the reserve for the ball housing, so the bottle is filled only up to the nominal volume.

Good to know

• Preparation before the first filling – we recommend washing the bottle, roller ball and cap, disinfecting them with isopropyl alcohol or ethanol and leaving them to dry completely.
• Essential oils and plastic – the glass and the steel roller ball are resistant to essential oils. The ball housing and the cap are made of polypropylene. With undiluted essential oils or blends with a higher proportion of solvents, we recommend checking how the plastic parts behave with your specific formulation.
• Tightness – a roll-on is often carried in a handbag or pocket. Before the product goes on sale, we recommend testing whether the contents leak around the roller ball when the bottle is turned upside down or shaken.
• Contents not visible – the amount of filling cannot be seen through black glass. The customer cannot tell from the bottle how much is left.
• Reuse – the bottle can be washed and refilled. The ball housing with the roller ball can be removed from the neck, but after refitting we recommend checking the tightness again.
• Other closures – the bottle has an 18/410 neck finish. You can find other closures with the same neck type and ready-made combinations in the Handymade range. For your own combination, we recommend checking the tightness and dispensing with your formulation.
• Recycling – before disposal, separate the ball housing with the roller ball and the cap from the bottle. The glass goes in glass recycling and the polypropylene cap in plastics.
