Amber Plastic Bottle, Black Pump, 300 ml

Plastic bottle, brown, black dispenser, 300 ml is a ready-made set for filling liquid and semi-liquid cosmetic preparations that are to be dispensed with one hand and without opening the cap. The brown PET bottle reduces light access to the contents and the black 24/410 dispenser releases a measured amount with each press. The set is therefore particularly suitable for body lotions, facial emulsions, shampoos, shower gels, liquid soaps and massage oils.

Both components have the same neck type, so the dispenser fits directly onto the bottle and seals properly. The 300 ml volume is a practical size for home production of a larger batch as well as for smaller product series.

Why choose this set

• Light protection – brown-tinted PET transmits less light than clear plastic, which slows the oxidation of oils and the degradation of light-sensitive ingredients. It is not a completely opaque container, so store the filled bottle away from direct sunlight.
• Hygienic dispensing – the contents do not come into contact with fingers and less air enters the bottle than with the wide neck of a jar. This reduces the introduction of microorganisms into the product, particularly with emulsions.
• Lightweight and shatterproof – PET is considerably lighter than glass and can withstand a drop from a washbasin or shelf. Suitable for the bathroom, shower and travel.
• Measured dose – each press releases approximately 1 ml of product. This simplifies usage instructions for the finished product and helps conserve the contents.

What products is it suitable for

The dispenser works best with contents of low to medium viscosity: body and facial lotions, light to medium-weight creams, shampoos, conditioners, shower gels, liquid hand soaps, cleansing gels, massage, body and cleansing oils. Thick body butters, balms and very firm creams will not pass through the tube or only with difficulty. For these, a jar or pot is more suitable.

PET is a common material for both water-based and oil-based contents. For preparations with a high proportion of undiluted essential oils, fragrance compositions or solvents (for example, a higher proportion of alcohol or D-limonene) we recommend testing in advance whether the bottle material and the dispenser seal soften or become cloudy.

Nominal and total volume

Nominal volume is the amount the bottle is designed for during standard filling, and this is the figure stated on the label of the finished product. Total volume to the brim is the physical volume up to the neck and is slightly larger. The difference provides a reserve for the tube and the body of the dispenser, which displace some of the contents upward when screwed in, and for the expansion of the contents with changes in temperature. The bottle should therefore be filled to the nominal volume, not to the brim. Otherwise, once the dispenser is fitted, the contents will be forced out through the thread.

What is good to know when filling

• Preparation before first filling – rinse both the bottle and dispenser, disinfect with isopropyl alcohol or ethanol and allow to dry completely. Residual water in the tube would dilute the first dose or introduce moisture into an anhydrous product.
• Priming the dispenser – after filling and screwing on, press the head several times without product until the tube fills and the preparation begins to come out. The first few doses may be smaller.
• Viscosity of emulsions – if the cream thickens more than expected after cooling, the dispenser will draw it slowly or with air bubbles. This can be resolved by slightly reducing the proportion of thickener or consistency agents in the formulation.
• Repeated use – after thorough washing and disinfection, the set can be refilled. The procedure can be found in the frequently asked questions below.
• Labelling – light or contrasting labels stand out well against the brown background. Bottle dimensions can be found in the parameters.
• Heat – PET softens at higher temperatures and may deform. Allow hot emulsions to cool to at least room temperature before filling and do not store filled bottles near a radiator or in a window.
• Recycling – the bottle is made of PET and the dispenser of PP. Separate them before disposal and sort each component according to the material code stated in the parameters.

Closures with the same neck type and further ready-made combinations of this bottle can be found in the Handymade range. When assembling your own combination, verify the seal, dispensing and behaviour of the packaging with the specific formulation.
