Clear Plastic Bottle, Black Aluminium Cap, 10 ml

A clear 10 ml PET medicine bottle with a black aluminium cap is packaging for small quantities of liquid cosmetics: serum samples, travel-size face and body oils, diluted fragrance blends or toners to try out. PET is lightweight and does not break when dropped, so the set withstands shipping samples to customers as well as being carried in a handbag. Through the clear walls you can see the colour of the contents and how much product is left, which you will appreciate with testers and samples more than with a large pack.

The set is declared suitable for contact with cosmetic products. The certificate for direct food contact applies to the bottle alone; the aluminium cap does not have it, so the set as a whole is intended for cosmetics.

What it is suitable for

• Samples and testers – a small volume is enough for several applications of a serum or oil, and customers can try the product without buying the full pack.
• Travel packs – a face oil, serum or toner for a few days, with no risk of breakage in luggage.
• Oil blends and serums – a carrier oil with active ingredients or a diluted fragrance, where the clear wall shows the clarity and colour of the blend.
• Decanting larger packs – pouring off a smaller quantity of an ingredient for the workshop or a case, so that the large bottle stays closed.

How the set works

The cap consists of an aluminium shell with an inner foamed polyethylene liner (EPE). When tightened by hand, the liner sits on the rim of the neck and seals it. It does not need to be tightened with great force. Before sending out samples, it is worth laying the filled bottle on its side or standing it upside down for a few hours and checking that the contents do not leak. The behaviour of the seal also depends on the viscosity and composition of the product.

The contents are poured out of the medicine bottle directly through the neck. If you need to dispense in drops or spray, you will find closures with the same neck type and ready-made combinations in the Handymade range. For your own combination, we recommend checking the seal and dispensing with your specific formulation.

Nominal and total volume

The nominal volume of 10 ml is the quantity the medicine bottle is designed for in normal filling. The total brimful volume is larger, because it also includes the space up to the neck. This difference serves as a reserve for the closure and for the expansion of the contents when the temperature changes. For that reason, fill up to the nominal volume, not to the brim; otherwise part of the product is pushed out when closing, or remains on the cap liner.

Good to know

• Light – clear PET does not protect the contents from light. Store oils and serums that are sensitive to oxidation in a box or in the dark.
• Essential oils and solvents – the material should not be exposed to aggressive chemicals. For undiluted essential oils, perfume compositions and alcohol-based preparations, first run a compatibility test on one bottle.
• Heat – PET is not intended for hot filling. Let the product cool to room temperature and do not store finished packs near a heat source.
• Reuse – after washing and disinfection, the bottle and the cap can be used again. For the cap, check that the foam liner is not compressed, torn or soaked with the previous contents.
• Recycling – the bottle goes in the plastics bin as PET, while the aluminium cap with the polyethylene liner is sorted separately, so separate them before disposal.
