Plastic bottle, clear round, white flip-top, 28/410, 500 ml

A 500 ml plastic bottle with a white flip top cap is a complete set for products that are dispensed repeatedly and in smaller amounts. The transparent wall shows how much content remains, the rounded shape is easy to hold, and the flip top opens with one finger. The 500 ml volume suits products with faster turnover, such as shower gels, shampoos, body lotions, liquid soaps or massage oils.

The set as a whole is approved for direct food contact and declared suitable for contact with cosmetics. Declarations of conformity and certificates are listed with the product.

What the set is suitable for

• Rinse-off cosmetics – shower gels, shampoos, conditioners and liquid soaps, where single-hand dispensing is appreciated even in the shower.
• Body lotions and light emulsions – liquid to medium-viscosity emulsions that flow out in a controlled stream when the bottle is tilted and gently squeezed.
• Massage and body oils – a larger pack for regular use; the cap opening allows dispensing drop by drop or in a thin stream.
• Food – home-use flavouring oils, syrups, dressings or herbal infusions dispensed directly from the bottle.

How the flip top cap works

The cap has a hinged lid with a small dispensing opening that snaps back shut after use. There is no need to unscrew and set aside the cap, which is practical especially with wet hands. The cap is made of white polypropylene, which gives a clean, simple look against the transparent bottle.

Dispensing behaviour depends on the viscosity of the contents. Thin liquids such as oils or liquid soaps flow out on their own when the bottle is tilted. Thicker gels and emulsions require a gentle squeeze. With very thick creams, dispensing through the small opening is slow and awkward. With very thin liquids such as tonics or hydrolats, the stream is harder to control and a different cap type is more suitable.

Filling and volume

Nominal volume is the volume the bottle is intended for under normal filling conditions. The total brim volume is the physical capacity up to the neck and is always slightly larger. The difference provides clearance for the cap and for expansion of the contents with temperature changes. The bottle should therefore be filled to the nominal volume, not to the brim; otherwise the contents are forced into the thread when closing and the cap will not seal properly.

Fill the bottle with contents cooled to room temperature. Warm emulsions or gels can deform the plastic, and once cooled they create negative pressure inside the sealed bottle that draws the wall inward.

Good to know

• Light protection – transparent plastic provides no protection from light. Products sensitive to light, such as those containing vitamins, essential oils or unstable dyes, require a dark container or an outer box.
• Essential oils and solvents – undiluted essential oils, concentrated fragrance compositions and products with a high alcohol content can degrade the plastic over time or cause it to release odour. For finished cosmetics with standard fragrance dosages, we recommend verifying packaging stability on a test sample.
• Labels – the rounded shape requires a label that wraps around the bottle body. Bottle dimensions are listed in the product parameters.
• Caps with the same neck finish – other caps with the same neck type also fit this bottle; ready-made combinations are available in the assortment. For a custom combination, we recommend verifying the seal and dispensing performance with your specific formulation.
• Recycling – both the bottle and the cap are plastic and, once emptied and rinsed, belong in the sorted plastic waste collection.
