Clear Plastic Bottle, Transparent Disc Top, 100 ml

A ready-made combination of a PET bottle with a nominal volume of 100 ml and a clear disc top cap with a 24/410 neck finish, ready for filling with shampoos, shower gels, liquid soaps, face and body lotions or lighter creams. The clear material shows the colour and consistency of the contents. The bottle is light and unbreakable, so it suits travel packs, samples and bathroom products where glass would be a risk.

The disc top opens by pressing one side of the flat cap and closes by pressing the opposite side, so the contents are dispensed without unscrewing the cap. The set is declared suitable for contact with cosmetic products, and the declaration of conformity is available with the product.

What the set is suitable for

• Rinse-off cosmetics – shower gels, shampoos, conditioners and liquid soaps that are dispensed with one hand directly in the shower.
• Body and face lotions – thinner emulsions that flow through the disc top opening when the bottle is slightly tilted and squeezed.
• Cleansing gels and micellar products – products with low to medium viscosity, where no sprayer or pump is needed.
• Samples and travel packs – the 100 ml volume and the unbreakable material suit smaller batches as well as packing into a cosmetic bag.

For very thick creams and butters the disc top is inconvenient, as the contents are difficult to squeeze through the opening. A jar or a bottle with a pump suits such products better.

How to work with the set

The bottle is filled up to the nominal volume, not to the brim. The brimful volume is the physical volume up to the neck. The difference between the two values is a reserve for the closure and for the expansion of the contents when the temperature changes, so the space above the surface should stay empty. If the bottle is overfilled, the contents are pushed out through the thread when the cap is screwed on.

Fill the product when it has cooled down. PET is sensitive to heat, and a hot emulsion or hot water can deform the bottle. Leave emulsions that continue to thicken after production to settle before filling, so that you can estimate the quantity correctly.

To dispense, tilt the bottle and squeeze it gently. After use, press the cap back down so that the opening closes and the product does not dry out or leak.

Good to know

Clear packaging does not protect against light. Preparations with sensitive ingredients, for example a high proportion of unsaturated oils, vitamin C or essential oils, change faster in a clear bottle. For such formulations choose dark packaging, or store them out of direct sunlight.

Aggressive substances do not belong in PET. Do not expose the packaging to aggressive chemicals. For a formulation with a high proportion of undiluted essential oils, solvents or fragrance compositions, first test how the packaging behaves on a small sample.

After thorough washing and disinfection, the bottle and the cap can be reused. When refilling, check that the thread of the bottle and of the cap is not damaged and that the disc top can be closed reliably. Both parts are made of recyclable plastics, the bottle of PET and the cap of PP, so separate them before disposal.
