White Plastic Bottle, White Disc Top, 200 ml

A white plastic 200 ml bottle with a white disc top closure is a ready-made set for dispensing liquid and medium-thick cosmetic products. The bottle is made of PET, is lightweight and yields enough when squeezed for the contents to be pushed out through the closure with ease. The white wall limits the amount of light reaching the contents, so it is also suitable for formulations with light-sensitive ingredients. The set is declared suitable for contact with cosmetics and is most often used for shampoos, shower gels, body lotions, conditioners or liquid soaps.

Only the bottle on its own has a certificate for direct contact with food. The disc top closure has no such declaration, so the set as a whole is intended for cosmetic products.

How to use the disc top closure

The closure has a disc on top. Pressing one side lifts the other side and opens the dispensing orifice. The contents are then squeezed out by pressing the bottle, and you control the amount by the strength of your grip. After use, the disc is pressed back down and the orifice closes. The whole closure can be operated with one hand, which is useful in the shower or at the sink, where the other hand is wet.

The size of the orifice is adapted to liquid and medium-thick products. Very thin liquids, such as toners or hydrosols, flow out less controllably. Thick creams and butters are difficult to squeeze through the orifice. If your formulation is borderline in consistency, we recommend testing the dispensing with the finished formulation before you fill a larger batch.

What the set is suitable for

• Shampoos and shower gels – a gel consistency is dispensed evenly through the disc top and the bottle returns to its shape after squeezing.
• Body and face lotions – thinner emulsions flow from the orifice in the required amount and do not run down the edge.
• Conditioners and thinner hair masks – one-handed opening proves its worth when washing your hair; check the thickness of the mask by test filling.
• Liquid soaps and cleansing hand gels – the contents are dispensed straight from the bottle without a pump, and the 200 ml volume lasts for normal use at the sink.
• Smaller batches for sale and home use – the 200 ml volume corresponds to the usual size of rinse-off cosmetics, and the white packaging is easy to label and match with the other products in your range.

Nominal and total volume

The nominal volume of 200 ml is the volume the bottle is designed for in normal filling. Physically, more fits into it right up to the neck. The difference is a reserve for the closure and for the expansion of the contents with changes in temperature or when the bottle is squeezed. The bottle is therefore filled to the nominal volume, not to the brim. A bottle filled right up to the neck would push the contents into the thread when first squeezed, and the closure would not seal as it should.

Good to know

If you want to combine the bottle with a different type of closure, you will find closures with the same neck finish as well as ready-made combinations in the Handymade range. For your own combination, we recommend checking the tightness, the dispensing and the behaviour of the packaging with your specific formulation.

The bottle and the closure can be washed and reused. Before each new filling, check the thread and the disc to see whether it still snaps firmly shut after frequent opening. At the end of their life, unscrew the closure; the PET bottle and the PP cap are recycled as two separate plastics.
