Green Glass Bottle, Silver Aluminium Cap, 50 ml

The green glass medicine bottle with a volume of 50 ml is supplied together with an aluminium cap, so the packaging is ready for filling and closing straight away. Green glass filters out part of the light, so it suits facial and body oils, oil serums, essential oil blends, tinctures or smaller trial batches that should not stand in direct sunlight. The narrow neck with an 18/410 neck finish is filled with a funnel, and the screw cap with a sealing liner closes it without any additional tools.

The set is declared as suitable for contact with cosmetic products. You will find the declaration of conformity with the product.

Suitable uses

• Oils and oil serums – glass does not react with vegetable oils or essential oil blends, and the contents can be dispensed from the narrow neck easily, drop by drop or in a thin stream.
• Tinctures and alcohol-based preparations – alcohol does not harm glass, and the cap with its liner keeps the contents tightly sealed.
• Massage and hair oils – a volume of 50 ml corresponds to one smaller batch for home use or for giving as a gift.
• Samples and test batches – when developing a formulation, a small amount is enough, and after washing you can use the bottle for the next trial.

How the set works

The aluminium cap with a silver finish has a liner made of EPE (foamed polyethylene) inside. When screwed on, it sits against the rim of the neck and seals the contents. The cap is tightened by hand, without prying or tools. After opening, simply put it back on and tighten it so that the liner sits flush again.

The bottle is filled through the neck with an 18 mm thread, and for thicker oils a small funnel helps. The glass withstands normal cleaning and repeated use, and the aluminium cap is lightweight.

You will find closures with the same neck type (stated in the parameters) and ready-made combinations in the Handymade range. If you are making your own combination, we recommend checking the tightness, the dispensing and the behaviour of the packaging with your specific formulation.

Volume and filling

The nominal volume of 50 ml is the volume the bottle is designed for in normal filling. The brimful volume, stated in the parameters, is the physical volume up to the top of the neck. The difference between them forms a reserve for the cap, any dropper and the expansion of the contents when the temperature changes. For this reason, fill to the nominal volume, not to the brim. Otherwise the contents are pushed into the thread when closing and the cap does not seal as it should.

Good to know

Green glass filters light, but it does not block it completely. With light-sensitive raw materials, for example essential oil blends or oils with a higher proportion of unsaturated fatty acids, store the bottle away from direct sunlight regardless.

The set is not declared for contact with food; the packaging is intended for cosmetic preparations.

When reusing, check the liner of the cap. If it is compressed, cracked or has absorbed the scent of the previous contents, replace the cap. Glass can be reused after thorough washing. When disposing of the packaging, separate the glass from the cap and sort them separately.
