Plastic bottle, round transparent, black shaped flip-top cap, 28/410, 1000 ml

This is a ready-made bottle and closure set: a clear round plastic bottle with a nominal volume of 1000 ml and a black moulded flip top cap with a 28/410 thread. It is ideal wherever a larger quantity of liquid product needs to be dispensed repeatedly and with one hand – typically for shampoos, shower gels and liquid soaps. The transparent bottle body shows the contents and the remaining amount, the lightweight plastic will not shatter and withstands everyday handling in the bathroom, workshop or when selling in litre packaging.

The set is declared as suitable for contact with cosmetics. A compliance certificate for direct food contact applies to the bottle alone; the cap does not hold one – the set as a whole is therefore intended for cosmetic products.

How the set works in practice

• One-hand dispensing – the flip top opens with the thumb and the contents are dispensed by squeezing the bottle. No unscrewing required, which is appreciated with wet hands in the shower or during work.
• Controlled flow – the cap opening releases the liquid gradually, so the product does not pour out all at once. Suitable for medium-viscosity to thick liquids that can be squeezed out.
• Closure after use – the folded cap protects the opening from dust and limits drying of the contents between uses.
• Transparent body – the colour, viscosity and any changes in the contents are visible, making it easy to check the fill level and useful for retail when the product should be seen.
• Black cap – the moulded closure gives the litre packaging a consistent appearance and complements both the clear bottle and dark labels.

Which products is the set suitable for

The 1000 ml volume and flip top make this set ideal for rinse-off products and larger everyday care formats: shampoos, shower gels, liquid hand soaps, conditioners, body lotions, massage and bath oils. It also works well as a refill pack from which customers transfer the product into smaller bottles at home.

Both water-based and oil-based contents are suitable. For very thin liquids (tonics, hydrolats) the flip top is less practical – the low-viscosity liquid flows out quickly and is difficult to control. For contents with a high proportion of essential oils or solvents, we recommend testing the behaviour of the plastic with the specific formulation, as certain ingredients may soften or cloud the plastic over time.

Nominal and total volume

The nominal volume is the volume for which the bottle is designed under normal filling conditions. The total volume to the brim is the physical capacity up to the neck and is always somewhat larger. The difference provides a headspace for the closure and for expansion of the contents with changes in temperature. The bottle should be filled to the nominal volume, not to the brim – an overfilled bottle is harder to close and the contents are forced under the cap when squeezed.

What is worth knowing before filling

• Preparation – before the first fill, wash both the bottle and the cap, disinfect with izopropylalkoholom or etanolom and allow to dry completely. Water residue inside the container is a source of microbial contamination.
• Temperature – hot filling is not suitable for a plastic bottle. Allow emulsions and gels to cool to room temperature before filling.
• Product consistency – very thick creams are difficult to dispense from the bottle. If the product does not flow under its own weight when tilted, consider a thinner texture or a different type of packaging.
• Reuse – the complete set can be reused after thorough washing and disinfection. When changing the contents, check that no fragrance or discolouration from the previous product remains in the plastic.
• Labelling – the rounded body requires a label that follows the curvature.
• Recycling – once empty, both the bottle and the cap belong in the sorted plastic waste collection.

Closures with the same neck type and further ready-made bottle and closure combinations are available in the Handymade range. With a custom combination, we recommend verifying the seal, dispensing behaviour and compatibility of the container with the specific formulation.
