Rounded Clear Plastic Bottle, Type B, White Plastic Cap, 300 ml

This clear 300 ml PET bottle with a white ribbed cap is a ready-made set for filling liquid and semi-liquid cosmetic products. The bottle is lightweight, it will not break if dropped in the shower, and the clear material lets you see the colour and the level of the contents, so you know how much product is left. The cap with a 24/410 neck finish is tightened by hand, and the contents are dispensed by pouring or by squeezing the bottle.

The 300 ml volume matches a common bathroom pack size: shower gels, shampoos, conditioners, body lotions and massage oils. It also suits toners, micellar waters or bath blends in a larger pack. Both the bottle and the cap are declared suitable for contact with cosmetic products.

What the set is suitable for

• Rinse-off cosmetics – shower gels, shampoos, liquid body scrubs and conditioners with a liquid to medium-thick consistency, dispensed into the palm by squeezing the bottle.
• Body lotions – the bottle stands stably on a shelf and thinner emulsions squeeze out of it well.
• Massage and body oils – through the clear wall you can see the colour and clarity of the oil. Pouring from the bottle with the cap unscrewed is easy to control.
• Toners and facial waters – aqueous solutions that are applied to a cotton pad or decanted into a smaller travel bottle.
• Test batches – 300 ml is enough to use a new formulation for several weeks and check how it behaves in the packaging.

Nominal volume and filling

The nominal volume of 300 ml is the volume the bottle is designed for in normal filling. The actual volume up to the brim is larger. The difference provides a reserve for the cap, for expansion of the contents when the temperature changes, and for the air that pushes the contents out when the bottle is squeezed. For this reason, fill only up to the nominal volume, not to the rim. An overfilled bottle overflows when the cap is tightened and is harder to dispense from.

Cap and dispensing

The white ribbed cap is made of polypropylene and has a foam polyethylene (EPE) liner. When tightened, the liner sits on the rim of the neck and seals the bottle. The ribbed surface is easy to grip even with wet hands. The cap is unscrewed completely, so the contents are dispensed by pouring or by squeezing the bottle. If you need a different way of dispensing, closures with the same neck type and ready-made combinations are available in the Handymade range. With your own combination, we recommend checking the tightness, the dispensing and the behaviour of the packaging with your specific formulation.

Preparation and reuse

Before the first filling, wash the bottle and the cap in warm water with a cleaning product, rinse them and disinfect them with isopropyl alcohol or ethanol. Leave them to dry completely with the neck facing down. Residual water would dilute the contents and increase the risk of microbial contamination. Follow the same procedure before every further filling. Do not pour boiling water into the bottle or put it in a dishwasher, as PET may deform at high temperatures.

Good to know

• Light – clear PET does not protect the contents from light. Store products with sensitive ingredients (vegetable oils prone to oxidation, vitamin C, essential oils) away from direct sunlight or choose darker packaging.
• Weight – the bottle is considerably lighter than glass of the same volume, which you will appreciate when shipping parcels and when handling it in the shower.
• Consistency of the contents – thick gels and creams are harder to squeeze out of the bottle. For such products, a thinner consistency or a different type of packaging will help.
• Recycling – the bottle is made of PET and the cap of polypropylene, and both materials belong in sorted plastic waste. Before disposal, rinse the bottle and unscrew the cap.
