Product description
This white plastic bottle with a black disc top cap, 300 ml, is a ready-made set for liquid and medium-thick cosmetic products that are dispensed by squeezing the bottle. The bottle is made of PET and the cap of PP. Both parts have a 24/410 neck finish and are declared suitable for contact with cosmetics. The white opaque wall limits the amount of light reaching the contents. The plastic is light and unbreakable, which you will appreciate in the shower and when shipping products to customers.
What it is suitable for
The 300 ml volume corresponds to a common pack size for everyday products. The set is suitable mainly for:
- Shower gels and shampoos – a liquid to slightly thicker consistency flows smoothly through the disc top opening, and the bottle returns to its original shape after squeezing.
- Conditioners and body lotions – medium-thick emulsions can be squeezed out without unscrewing the cap.
- Liquid soaps and cleansing gels – the opening closes with a single press after use, so any product left on the neck does not dry out quickly.
The disc top is not suitable for thick creams or butters, as the contents are hard to squeeze through the small opening. For very thin liquids, such as toners or oils, we recommend checking the tightness and dispensing with your specific formulation, or choosing a different type of closure.
How to use the set
The disc top cap is opened by pressing the edge of the disc. One side is pushed down and the opposite side lifts up, uncovering the dispensing opening. The contents flow out when you squeeze the bottle, and when you release it the bottle draws air back in. It is closed by pressing the disc the other way, without any twisting. Customers can use it with one hand, even a wet one.
The nominal volume is the volume the bottle is designed for under normal filling. The volume up to the brim of the neck is larger. The difference provides room for the cap and for the expansion of the contents when the temperature changes, so the bottle is filled to the nominal volume, not to the brim. If it is overfilled, part of the contents is pushed out through the thread when the cap is screwed on, and the bottle becomes harder to squeeze.
Before the first filling, wash the bottle and the cap, disinfect them with isopropyl alcohol or ethanol and leave them to dry completely. Residual water in the packaging shortens the stability of water-based products and puts a strain on the preservative system.
Good to know
The set as a whole is intended for cosmetics. The bottle on its own has a certificate for direct food contact, but the disc top cap does not, so we do not recommend the set for food use.
PET is commonly used for both water-based and emulsion products. For formulations with a higher proportion of essential oils, solvents or alcohol, leave the filled bottle to stand for several weeks. Check that the wall does not soften or deform and that the cap continues to seal. Do not expose the packaging to aggressive chemicals.
Once empty, the packaging can be washed and reused. After prolonged use, the disc top collects dried product in the opening, so rinse it thoroughly with warm water when refilling. The bottle and the cap belong in sorted plastic waste, and you should separate them before disposal.
The bottle is not intended for hot filling. Leave emulsions and gels to cool before filling, otherwise the PET wall may deform and the contents will create a vacuum in the bottle as they cool.
You can find closures with the same 24/410 neck finish and other ready-made packaging + closure combinations in the Handymade range. If you combine parts yourself, check the tightness, dispensing and behaviour of the packaging with your specific formulation.
