Plastic bottle, clear round, black cap, 750 ml

Plastic bottle 750 ml with black cap – complete set for larger packaging

The plastic bottle 750 ml with black cap is a ready-to-use packaging and closure set: a clear round plastic bottle and a black screw-on cap for the 28/410 neck. It is suitable wherever you need to fill a larger quantity of a liquid or slightly viscous product and keep it securely closed – shower gels, shampoos, conditioners, liquid soaps, body lotions, massage oils or tonics in larger sizes. The transparent wall shows the contents and their colour. The plastic is lightweight and will not shatter if dropped, which is appreciated in the shower, at market stalls or during transport.

The set as a whole is approved for direct food contact and declared suitable for cosmetic products. The same bottle can therefore also be used for household oils, syrups, herbal infusions or fruit juices. The declaration of conformity is available on the product page.

What the set is suitable for

• Rinse-off cosmetics – shower gels, shampoos, liquid soaps and conditioners, where a larger volume is used up quickly and the transparent bottle shows how much content remains.
• Body and massage preparations – body lotions, massage oils and oil blends that are dispensed in larger amounts.
• Aqueous and alcoholic preparations – tonics, facial waters and herbal or alcoholic skin infusions without a high proportion of essential oils.
• Bulk storage – a reservoir of finished product from which smaller pump or spray bottles are refilled.
• Food use – household oils, syrups, dressings and infusions, as the complete set is approved for food contact.

How to work with the set

The bottle is filled to the nominal volume, not to the brim. The nominal volume is the volume for which the container is designed under normal filling conditions. The total brim-full volume is the physical capacity up to the neck. The difference between the two provides headspace for the closure and for expansion of the contents when temperature changes – this headspace is useful for products filled warm or for thicker emulsions.

The cap screws onto the 28/410 neck and seals the bottle for transport and storage. For daily dispensing in the shower, a flip-top or one-hand closure is generally more convenient. Closures with the same neck type and ready-made combinations are available in the Handymade range. For custom combinations, we recommend verifying the seal and the behaviour of the packaging with your specific formulation.

Good to know

Transparent plastic does not protect the contents from light. Products sensitive to light – preparations containing vitamin C, retinol, unstable vegetable oils or essential oils – are better suited to dark glass or an opaque container. If you do fill them into this bottle, store it away from direct sunlight.

For formulations with a high proportion of essential oils, neat alcohol or solvents, we recommend verifying the suitability of the container by filling it as a test and observing it for several weeks. Watch for deformation, cloudiness of the wall or release of odour.

The set is suitable for repeated use. Once empty, simply rinse the bottle with warm water and a mild detergent, disinfect and leave to dry. Do not boil the bottle; hot water can deform the plastic. Keep the cap dry and clean so that the thread retains its seal.

At the end of its service life, both components belong in sorted plastic waste; the cap is made of HDPE.
