Amber Glass Square Bottle, Glossy Gold Black Pump With Clear Overcap, 10 ml

The glass medicine bottle with a pump is packaging for small volumes of cosmetics that you want to protect from light and dispense in small amounts: face serums, oils with vitamins, active ingredient concentrates or test batches. The amber square 10 ml bottle is fitted with a plastic pump with a glossy black and gold cover and a clear overcap. Amber glass filters light, the pump dispenses the contents without opening the bottle, and the straight square shape stands firmly on a shelf, including in the bathroom.

The set is intended for cosmetics. The glass bottle on its own has a food-contact certificate; the pump does not.

How the set works

The pump with an 18/415 neck finish fits the bottle with an 18/410 neck finish and holds firmly once tightened. One press dispenses approximately 0.3 ml of the contents, which corresponds to a usual dose of face serum or fluid. The clear overcap protects the pump opening from dust and also shows whether any product has been left in it. The pump is made of plastic (PP) and aluminium.

The dip tube reaches the bottom of the bottle and draws the contents from below, so the pump dispenses even when the level is low. When using it for the first time, press the pump several times until it primes.

What it is suitable for

• Face serums and fluids – liquid to slightly thick textures that the pump draws up and dispenses in small amounts.
• Oil serums and oil blends – amber glass limits the access of light, which speeds up the oxidation of unsaturated oils.
• Active ingredient concentrates – a small volume is used up quickly, which suits serums with vitamin C, retinol or peptides.
• Samples and test batches – you can try out a formulation or hand it out to customers in packaging that looks like a finished product.
• Eye serums and products for the décolleté area – the dose per press is small, which suits products where only a few drops are applied.

A pump with a dip tube does not draw thick creams and butters. For such textures, a jar or a lotion pump without a dip tube is suitable.

Nominal volume and filling

The nominal volume of 10 ml is the amount the bottle is designed for in normal filling. The total volume up to the neck is larger. The difference is a reserve for the dip tube and the pump mechanism, which take up part of the space once fitted, and for the expansion of the contents when the temperature changes. The bottle is therefore filled to the nominal volume, not to the brim. If it were filled up to the neck, the contents would be pushed out through the thread when the pump is tightened.

A syringe or a measuring cup is useful for measuring small batches. For larger quantities, filling is done by weight, based on the density of the product.

Good to know

• Preparation before first filling – wash the bottle and the pump, disinfect them with isopropyl alcohol or ethanol and let them dry completely. Residual water in the pump dilutes the first dose and can introduce contamination into an anhydrous product.
• Reuse – the glass can be washed and disinfected repeatedly. Clean the pump before the next filling following the procedure in the frequently asked questions below.
• Glass and heat – do not fill the bottle with a hot emulsion straight from the hob. With a sudden temperature difference the glass may crack, so let the contents cool down first.
• Essential oils and solvents – plastic parts made of polypropylene resist common cosmetic oils and emulsions. For products with a high proportion of essential oils, alcohol or solvents, we recommend checking the behaviour of the pump in the finished formulation.
• Preservation of the contents – the pump limits contact of the contents with hands and air better than an open bottle, but it does not replace a preservative. Water-based and emulsion products must be preserved in this packaging as well.
• Recycling – glass goes with glass. The pump contains plastic and aluminium, so separate it from the bottle before sorting.

You can find other closures for this bottle and ready-made bottle + closure combinations in the Handymade range. If you make your own combination, we recommend checking the seal, the dispensing and the behaviour of the packaging with your specific formulation.
