White Plastic Bottle, White Plastic Disc Top with Matte Rose Gold Aluminium Collar, 150 ml

A white PET bottle with a capacity of 150 ml and a disc top cap in a matte rose gold finish form a ready-made set for liquid and medium-thick products that are dispensed straight into the palm or onto a sponge. The cap opens by pressing one side of the disc, the contents flow out through a small opening, and pressing it again closes the bottle, all with one hand. The bottle is lightweight, so it suits the shower as well as travel. The set is declared suitable for contact with cosmetics.

What the set is suitable for

A disc top closure works best with products that are liquid but not completely watery, so that they flow out in a controlled way when the bottle is tilted and do not drip once it is closed. The 150 ml white bottle with this cap is therefore mainly filled with:

• Body and face lotions – light emulsions that are dispensed into the palm and spread over a larger area.
• Shower gels and shampoos – 150 ml is a travel or trial size.
• Conditioners and hair masks of thinner consistency – as long as they flow by gravity; very thick masks will not pass through the disc opening.
• Micellar waters and cleansing emulsions – with watery products, we recommend checking that the disc seals as well as you expect after closing.
• Liquid hand soaps – for the bathroom, where a white bottle with a metal cap will not look out of place.

Appearance also matters for gift sets and small batches. The aluminium shell of the cap in a matte rose gold finish with a white centre matches the white bottle.

How dispensing works

The cap disc tilts when one side is pressed. The open side uncovers the opening, through which the contents are dispensed by squeezing the PET bottle or by gravity when the bottle is turned upside down. Pressing the opposite side closes the opening and the disc sits flush again. The cap has an aluminium shell, and the rest, including the white centre, is made of polypropylene.

Nominal volume and filling

The stated 150 ml is the nominal volume, that is, the amount the bottle is designed for under normal filling. The physical volume up to the brim of the neck is larger. This difference serves as a reserve for the cap, for the air above the surface, and for the expansion of the contents with changes in temperature. Fill the bottle to the nominal volume, not to the brim. If the bottle is overfilled, the contents are pushed into the thread when the cap is screwed on, and the disc top cap may then leak at the neck.

Good to know

Before first use, wash and rinse the bottle and the cap, and disinfect them with isopropyl alcohol or ethanol, then leave them to dry completely with the neck facing down. Residual water in an empty bottle puts unnecessary strain on the preservative system of the product.

PET is not to be filled hot. Let emulsions, gels and shampoos cool to room temperature and only then pour them in. Heat deforms the wall of the bottle and can affect the seal at the thread. The packaging should not be exposed to aggressive chemicals. For products with a high proportion of essential oils or solvents, we recommend checking beforehand how the bottle wall and the inside of the cap behave with your specific formulation.

The bottle on its own has a certificate for direct contact with food; the disc top cap does not. The set as a whole is intended for cosmetics.

Both the bottle and the cap can be reused after washing. Between different products, we recommend thorough disinfection and a check that the disc still sits firmly. For recycling, the PET bottle is handed in as plastic, while the cap combines aluminium with polypropylene and is therefore sorted separately from the bottle. You can find closures with the same 24/410 neck finish and other ready-made combinations in the Handymade range. If you make your own combination, we recommend checking the tightness, the dispensing and the behaviour of the packaging with your specific formulation.
