Plastic bottle, clear round, matte black flip-top, 28/410, 1000 ml

A ready-to-use set for large-format packaging: a clear plastic bottle 1000 ml with a round shape and a matte black flip-top cap with a 28/410 neck thread. The combination is intended for liquid and gel cosmetic products dispensed by squeezing the bottle – shower gels, shampoos, liquid soaps, and body lotions. The clear plastic reveals the contents and their colour; the matte black cap gives the packaging a clean, neutral look that works well with custom labels. The set is declared suitable for contact with cosmetic products.

How the set works

The flip-top cap opens with a single thumb movement and snaps shut just as easily after use. Dispensing is done by squeezing the bottle: the contents flow through the small opening in the cap, allowing good control over the amount without fully opening the bottle. It works best with medium to high viscosity contents such as gels, shampoos, or lotions.

The cap threads onto a 28/410 neck. If you want to pair the bottle with a different type of closure, caps with the same neck size and other ready-to-use combinations are available in the Handymade range. When assembling your own combination, we recommend verifying the seal, dispensing behaviour, and compatibility of the packaging with your specific formulation.

Suitable for products such as

• Shower gels and liquid soaps – the 1000 ml volume corresponds to a larger home or salon size; the flip-top allows convenient dispensing directly in the shower or at the sink.
• Shampoos and conditioners – thicker textures dispense through the cap opening in a controlled manner without opening the entire bottle.
• Body lotions and massage emulsions – squeeze dispensing works reliably for medium-viscosity emulsions; a different type of packaging is more suitable for very thick creams.
• Refill stock for topping up – the larger volume works well as a reserve for refilling smaller containers in the bathroom or for travel.

Nominal and total volume

Nominal volume is the volume for which the bottle is designed under standard filling conditions. Total volume to the brim is the physical capacity up to the neck and is slightly larger. The difference provides a margin for the cap and for expansion of the contents with temperature changes. Fill to the nominal volume, not to the brim – an overfilled bottle is harder to close and may leak around the thread when squeezed.

Useful things to know

• Preparation before first filling – we recommend washing both the bottle and cap, sanitising with isopropyl alcohol or ethanol, and allowing them to dry completely. Residual moisture inside the packaging can reduce product stability.
• Light – clear plastic does not protect the contents from light. Products with light-sensitive ingredients, such as those with a higher proportion of essential oils or plant oils prone to oxidation, should be stored away from direct light or packed in a dark container.
• Essential oils and solvents – for contents with a high proportion of essential oils, alcohol, or other solvents, verify the behaviour of the plastic with your specific formulation, especially under prolonged contact.
• Heat – filling with hot contents is not recommended. Allow the product to cool before filling to prevent deformation of the bottle.
• Reuse – after thorough cleaning and sanitisation, the set can be reused. Before refilling, check that the cap still snaps firmly shut and that the opening is not blocked by dried product.
• Labelling – the rounded shape of the bottle requires a label adapted to the curvature; bottle dimensions are listed in the product parameters. The matte black cap is colour-neutral and suits a wide range of labels.
• Food – the food-contact certificate covers the bottle separately; the cap does not carry such a declaration. The set as a whole is therefore intended for cosmetic use only.
• Recycling – both the bottle and the cap are made of plastic and belong in sorted plastic waste.
