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 and disinfecting both the bottle and cap with isopropyl alcohol or ethanol and allowing them to dry completely. Residual moisture inside the container may reduce product stability.
• Light – transparent plastic does not protect the contents from light. Products containing sensitive ingredients, such as a higher proportion of essential oils or vegetable oils prone to oxidation, should be stored away from direct light or packed in dark packaging.
• Essential oils and solvents – for contents with a high proportion of essential oils, alcohol, or other solvents, verify the plastic's behaviour with the specific formulation, particularly under prolonged contact.
• Heat – filling with hot contents is not recommended. Allow the product to cool before filling to prevent the bottle from deforming.
• Reuse – after thorough washing and disinfection, the set can be reused. Before the next filling, check that the cap still clicks firmly into place and that the opening is not blocked by dried residue.
• Labelling – the rounded shape of the bottle requires a label adapted to the curvature; bottle dimensions are listed in the specifications. The matte black cap is colour-neutral and suits a wide range of label designs.
• Food – the food-contact certification applies to the bottle alone; the cap is not covered. The set as a whole is therefore intended for cosmetic use.
• Recycling – both the bottle and the cap are made of plastic and belong in sorted plastic waste.
