Blue Glass Bottle, Lotion Pump, 30 ml

The blue glass bottle with a lotion pump is ready-made packaging for 30 ml of cream, thicker serum or light emulsion. With every press, the black lotion pump dispenses a small, always identical amount of product. The contents are not scooped out with fingers, and the whole neck does not need to be opened as with a jar. In addition, blue glass lets less light through to the contents than clear glass, which is useful for formulations with vegetable oils, vitamins or extracts.

The bottle and the pump are supplied together as a set, and both parts are suitable for contact with cosmetics. The set is intended for cosmetic products where you want to offer your customers hygienic dispensing.

What the set is suitable for

• Creams and emulsions – the pump is designed for thinner to medium-thick O/W creams, which the dip tube draws up and the outlet pushes out in a continuous dose.
• Thicker serums and gels – viscous serums and gel bases are dispensed in small doses without the dripping that can occur with a dropper.
• Eye creams and products for the décolleté area – with a small dose per press, the contents are used up slowly and in a controlled way, so active formulations are not wasted.
• Samples and travel sizes – a hand cream or creamy serum in a small pack that can be used with one hand and without opening.

Dispensing and filling

One press dispenses approximately 0.12 ml of product. For an eye cream or serum, one or two presses are enough; for a hand cream, several. You can use this amount as an approximate dose in your instructions for use.

The bottle has a nominal volume of 30 ml, that is, the volume it is intended for in normal filling. The brimful volume given in the parameters is the physical volume up to the neck. The difference between the two is a reserve for the dip tube and the body of the pump and for the expansion of the contents when the temperature changes. Fill to the nominal volume, not to the brim, otherwise the cream will leak around the thread once the pump is screwed on.

Thicker creams are best filled into the narrow neck with a syringe without a needle or a small funnel, so that no air bubbles form in the neck. After fitting the pump, press it several times to prime it until the dip tube fills and the product starts to come out.

Good to know

Before first filling, wash the bottle, disinfect it with isopropyl alcohol or ethanol and leave it to dry completely. Rinse the pump with the same solution, pump it without any product and leave it to dry with the dip tube uncovered. Residual water in the dip tube would dilute the first dose of cream.

A pump with a dip tube is not an airless system. With every press, air is drawn into the bottle to replace the dispensed volume. Water-based and emulsion formulations therefore need effective preservation, just as in a jar. The advantage over a jar remains that no contamination from fingers gets into the contents.

The pump does not draw up very thick balms, butters and creams with a high proportion of waxes. Thin oils, toners or hydrosols will pass through, but the outlet drips afterwards and the dose is imprecise. For such contents, a dropper or a sprayer with the same neck finish is more suitable.

The pump is made of polypropylene. For formulations with a high proportion of essential oils, alcohol or solvents, we recommend checking in the finished formulation that the pump still seals and works smoothly after several weeks.

Do not pour hot emulsion into the glass straight from the pot. Let it cool to at least lukewarm, because glass does not withstand a sharp temperature difference and the bottle may crack. The glass bottle withstands repeated use after thorough washing and disinfection. The pump is harder to clean, so if residues of an old formulation have dried on, it is better to replace it.

Closures with the same neck finish as given in the parameters, and ready-made combinations, can be found in the Handymade range. If you combine the bottle with a different closure, we recommend checking the seal and dispensing with your specific formulation.

Once the contents are used up, separate the pump from the bottle; glass and plastic go into separate recycling collection.
