Amber Round Sirup Glass Bottle, 28 mm, Rose Gold Aluminium Cap, 100 ml

The amber glass medicine bottle with a volume of 100 ml, supplied with a rose gold aluminium cap, is packaging for contents that are harmed by light: facial and body oils, serums, toners, alcohol tinctures or blends with essential oils. The cap screws onto the PP28S neck finish and closes the bottle without a dispensing element, so the contents are poured out or measured as needed. The set is declared suitable for contact with cosmetic products.

What it is suitable for

• Oils and oil serums – glass does not react with the oil phase, and the amber colour slows its degradation by light. For oils sensitive to oxidation, this determines how long they keep their scent and colour.
• Toners, facial waters and hydrosols – water-based contents require preservation, but the packaging remains neutral with them and can be thoroughly disinfected before filling.
• Tinctures and alcohol extracts – alcohol does not attack glass.
• Blends with essential oils – concentrated fragrance components that could damage plastic packaging over time are risk-free in glass.
• Retail and gift packaging – a dark bottle with a metal cap looks complete even without additional packaging.

Volume and filling

The nominal volume is the amount the packaging is designed for under normal filling. The brimful volume is the physical volume of the bottle up to the neck, and you will find it in the parameters. The difference between the two values provides a reserve for the closure and for the expansion of the contents when the temperature changes. The bottle is therefore filled up to the nominal volume, not to the brim. If it were filled right up to the neck, the contents could be pushed into the thread when the cap is screwed on and damage the seal.

Cap and seal

The aluminium cap has an EPE foam liner on the inside, which sits against the rim of the neck when tightened and seals the bottle. Tighten it by hand without using force. Aluminium is a soft metal, and the thread may become deformed if overtightened. For contents with a higher proportion of alcohol or essential oils, we recommend checking the tightness on one filled bottle, ideally laid on its side for several days.

Closures with the same neck type and ready-made combinations can be found in the Handymade range. If you create your own combination, we recommend checking the tightness, dispensing and behaviour of the packaging with your specific formulation.

Good to know

The food-contact certificate applies only to the glass bottle on its own. The cap does not have such a certificate, so the set as a whole is intended for cosmetics, and we do not recommend it in this configuration for homemade oils or syrups.

Before the first filling, wash the bottle and the cap, rinse them and disinfect them with isopropyl alcohol or ethanol. Leave them to dry completely with the neck facing down, as residual water in oil-based contents promotes the growth of microorganisms. The same procedure applies to repeated use. Also check that the liner in the cap is not compressed or soaked with the previous contents.

Once used up, the glass bottle belongs in glass recycling and the aluminium cap in metal recycling. Before handing them in, it is enough to empty and rinse the packaging.
