Clear Plastic Bottle, Black Lotion Pump with Black Overcap, 10 ml

A clear plastic medicine bottle with a volume of 10 ml and a black lotion pump make a ready-to-use set for small packs of creams, face serums, eye gels and light emulsions. The pump dispenses a small, repeatable amount with each press, so it suits products that the customer dispenses precisely and without touching the contents with their fingers. The bottle is made of PET. It is lightweight and does not shatter when dropped, as glass does, which is appreciated by makers who send samples by post or offer travel sizes. The clear wall shows the colour and consistency of the contents, which is useful for coloured serums, tinted creams or gels, where appearance sells.

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

What the set is suitable for

• Face serums and eye creams – the small volume and precise dispensing match products that are used in pea-sized amounts.
• Samples and testers – with 10 ml, a few doses are enough to try the product, and the customer receives it with the same type of closure as the full-size pack.
• Hand creams for your handbag – the bottle fits even in a small pouch.
• Light emulsions and gels – the pump works best with contents that at least flow slowly. A thick balm or ointment will not pass through it.

How the lotion pump works

The pump, screwed onto the neck of the bottle, draws the contents up through a tube from the bottom. Before first use, press the head several times to prime the system so that the first dose is dispensed in full. The dose per press is small and approximately the same each time, which makes it easier to dispense active serums, where only a few drops are applied per use.

When filling, fill the bottle up to the nominal volume, fit the pump and tighten it by hand. The thread on the plastic does not need to be tightened by force, and doing so could damage it.

Nominal and total volume

The nominal volume is the amount the packaging is designed for under normal filling, in this case 10 ml. The total volume up to the rim of the neck is slightly larger. The difference serves as a reserve for the submerged part of the pump and tube. For this reason, fill up to the nominal volume. A bottle filled to the brim will overflow when the pump is screwed on and the contents will get into the thread.

Good to know

Clear PET does not provide protection from light. Serums with vitamin C, retinoids or light-sensitive plant extracts last a shorter time in clear packaging than in amber or blue glass. For such formulations, we recommend dark packaging or selling the product in a box.

The packaging is not intended for aggressive chemicals. For anhydrous products with a high proportion of essential oils, for alcohol tinctures or for contents with solvents, we recommend checking how the packaging behaves on a single piece, for example with a one-week test at room temperature. Watch whether the wall turns matte or soft, or whether the pump seal swells.

Hot filling is not suitable for PET, and the packaging must be protected from heat. Let the emulsion cool before filling, as warm contents deform the bottle.

Before first filling, wash the bottle and the pump in warm water with a small amount of washing-up liquid, rinse them, disinfect them with isopropyl alcohol or ethanol and leave them to dry completely upside down. Residual water in the tube would introduce a microbial risk into the product. The set can be reused, but we recommend a new pump when changing the type of product.

For recycling, the PET bottle and the polypropylene pump are separated and sorted individually according to their material codes.
