White Plastic Bottle, Transparent Disc Top, 200 ml

The white plastic 200 ml bottle with a clear disc top cap is designed for cosmetic products that are dispensed straight into the palm: shower gels, shampoos, conditioners, body lotions and liquid soaps. The cap opens by pressing one side of the disc, the contents flow out through the central opening, and the same movement closes it again. There is nothing to unscrew or put down, so it is easy to use in the shower and at the sink.

The bottle is made of PET, it is lightweight and, unlike glass, it does not break when dropped. The white opaque wall limits the amount of light reaching the contents, which helps with products containing colour or fragrance components that are sensitive to light. Through the clear cap you can see whether any product has been left in the channel under the disc. The set is declared suitable for contact with cosmetics. In addition, the bottle on its own has a certificate for direct contact with food, while the disc top cap does not have such a certificate, so the set as a whole is intended for cosmetics.

What the set is suitable for

• Shower gels and shampoos – liquid to medium-thick contents flow smoothly through the disc top opening, and the dose can be estimated by how hard you press.
• Body lotions and lighter emulsions – a thinner to medium-thick consistency dispenses well. Thick creams do not pass through the opening or flow out slowly.
• Liquid soaps and cleansing gels – the cap does not need to be unscrewed during normal use, which you will appreciate with wet hands.
• Conditioners and hair masks of a thinner consistency – the 200 ml volume corresponds to a common pack size.
• Body and massage oils – oils flow easily through the disc top, so control the dose by pressing gently. For contents with a higher proportion of essential oils, we recommend testing how the packaging behaves in the finished formulation.

A thick cream emulsion that does not start to move on its own when the bottle is turned upside down is not suitable for the disc top. For such contents, a jar or a bottle with a pump is a better choice.

Filling and volume

The nominal volume of 200 ml is the amount the bottle is designed for during normal filling. The physical volume up to the brim of the neck is larger, and the difference provides a reserve for the cap and for the expansion of the contents with changes in temperature. The bottle is therefore filled to the nominal volume, not to the brim. If it were filled to the brim, the contents would be pushed into the thread when the cap is screwed on, and the disc top could leak.

How to dispense through the disc top

The disc top has two positions. In the closed position the disc fits tightly and the central opening is sealed; in the open position one side of the disc lifts and the contents flow out. To dispense, simply turn the bottle over and press lightly. The amount depends on the force and duration of the press. With liquid contents, dispense carefully, as they flow out quickly. After use, press the disc back down so that the opening closes and the contents do not leak when the bottle is stored horizontally.

Thinner contents flow out on their own once the bottle is turned over, medium-thick contents need to be pressed out, and very thick contents pass through the central opening with difficulty. If you are formulating a body lotion or conditioner for this set, adjust the viscosity so that the product flows with only a light press.

Good to know

• Preparation before first filling – wash the bottle and the cap, disinfect them with isopropyl alcohol or ethanol and leave them to dry completely. With the cap, pay attention to the channel under the disc, where moisture remains.
• Reuse – after washing, the bottle can be filled again. The disc top is harder to clean because product residue stays in the inner channel. Rinse it with warm water in the open position and leave it to dry. A stronger scent of the previous contents may partly remain in the plastic.
• Material and contents – PET withstands common water-based and emulsion cosmetic formulations. For contents with a high proportion of alcohol, concentrated essential oils or other solvents, first test how the packaging behaves on a trial sample. Do not expose the bottle to aggressive chemicals.
• Other caps – the bottle has a 24/410 neck finish. You will find caps with the same neck type and ready-made bottle and cap combinations in the Handymade range. If you make your own combination, check the tightness and dispensing with your specific formulation.
• Recycling – the bottle is made of PET and the cap of PP, and both components belong in sorted plastic. Unscrew them and rinse them before disposal.
