Blue Glass Bottle, Lotion Pump, 50 ml

The blue glass bottle with a lotion pump is designed for filling and dispensing emulsions that should not be scooped out with the fingers directly from the packaging. One press of the pump releases a small dose that is always roughly the same, so it is particularly suitable for face and eye creams, thicker serums and hand creams in travel or trial sizes. Blue glass lets through less light than clear glass, which helps with contents containing vegetable oils, vitamins or other light-sensitive active ingredients.

The bottle has the shape of a medicine bottle: straight walls, a narrow neck and a stable base. The black pump with a clear overcap screws directly onto the neck and draws the contents up through a dip tube from the bottom. The set is declared suitable for contact with cosmetic products; you will find the declaration of conformity with the product. It is not approved for contact with food, so it is intended exclusively for cosmetics.

Benefits of the pump and blue glass

• Hygienic dispensing – the contents are dispensed without you having to reach into them, so no dirt from your hands gets in during use. The preservative system of the cream is therefore under less strain than in an open jar.
• Measured dose – one press corresponds to approximately 0.12 ml. With eye creams and concentrated emulsions, the amount is easier to estimate and the product is not wasted.
• Light protection – blue glass absorbs part of the light and slows down changes in the fragrance and colour of light-sensitive ingredients. However, it does not offer the full protection of amber or opaque packaging.
• Glass without odour or interactions – it does not transfer any odour to the contents and does not absorb aromatic ingredients, so it is also suitable for creams with a higher proportion of essential oils or fragrance composition.

What to fill the bottle with

The lotion pump is built for emulsions of medium thickness. It handles common face and body creams of the O/W type, thicker serums and light balms that can be pumped. Very solid ointments, anhydrous butters based on shea butter, or preparations with coarser particles, such as scrubs and creams with powder pigments, overload or clog the pump.

This closure is not intended for liquid oils, toners and water-based serums. Thin contents may leak from the pump outlet and the dose will not be accurate. For such formulations, a dropper or sprayer for the same type of neck is suitable.

Closures with the same type of neck, as well as ready-made bottle + closure combinations, can be found in the Handymade range. If you make your own combination, we recommend checking the tightness, dispensing and behaviour of the packaging with your specific formulation.

Nominal and total volume

The nominal volume is the volume the bottle is designed for under normal filling. The total brimful volume is the physical volume up to the neck. The difference between them forms a reserve for the dip tube and the body of the pump, and for the expansion of the contents with temperature changes. The bottle is filled up to the nominal volume. If you fill it to the brim, the cream will overflow when the pump is screwed on and the pump will be flooded during the first presses.

Good to know

Preparation before filling. Before the first filling, wash the bottle and the pump, disinfect them with isopropyl alcohol or ethanol and let them dry completely. Residual water in the tube would mix into the first doses of cream. The pump is disinfected by pumping the alcohol through it several times and then letting it evaporate.

Filling emulsions. Fill the cream only after it has cooled to room temperature. Glass does not tolerate sudden temperature changes well, and a hot emulsion would also change in volume as it cools in the closed bottle. Thicker creams are easier to fill into the narrow neck from a bag with a snipped corner or through a small funnel.

Pump tube. After screwing the pump on, check that the end of the tube reaches the bottom. Only then will the last layer of the contents be used up. If the tube is too long for the bottle, shorten it with a diagonal cut so that it does not stick to the base.

Reuse. Once empty, the bottle can be washed and used again. When changing the contents, first pump warm water with a small amount of cleaning product through the pump, then clean water and finally alcohol. If cream has dried in the mechanism, the pump becomes stiff or dispenses irregular doses and it is better to replace it.

Recycling. After the contents are used up, the glass bottle belongs with glass, while the pump is made of polypropylene (PP 5) and is sorted as plastic. Before disposal, it is enough to separate the two parts.
