Plastic bottle, clear round, black cap, 28/410, 500 ml

A plastic bottle with a capacity of 500 ml and a black screw cap is a ready-made set for larger quantities of liquid products. Clear plastic shows the colour of the contents and the remaining amount, is lightweight and will not break if dropped, which is useful in the bathroom, workshop or when shipping products. The solid cap closes the neck when tightened; the contents are poured or decanted from the bottle.

The set is suitable for contact with cosmetic products and is also approved for direct food contact — both the bottle and the cap. It is therefore suitable for cosmetics as well as home-made food products.

What the bottle and cap are suitable for

A volume of 500 ml is practical wherever a product is used up quickly or is used to refill smaller containers:

• Rinse-off cosmetics – shampoos, shower gels, liquid soaps and bath foams that are used in larger amounts.
• Refill supplies – a stock container used to top up a smaller bottle with a pump or spray.
• Water-based and oil-based preparations – hydrolats, tonics, massage oils and body oils.
• Working supplies during production – prepared solutions, macerated oils or measured-out phases, where seeing the contents and their level is an advantage.
• Food use – syrups, oils, vinegars and herbal extracts from home production.

The solid cap does not dispense the contents. With thicker products such as creamy shampoos and conditioners, a dispensing closure is therefore more convenient.

Bottle and cap as a unit

The cap is made of HDPE. Its black colour forms a strong contrast with the clear bottle body, giving the packaging a neat appearance even without a complex label. The rounded shape sits comfortably in the hand.

Closures with the same neck type (stated in the product specifications) and other ready-made combinations are available from Handymade. With a custom combination, we recommend checking the seal, dispensing performance and the behaviour of the container with the specific formulation.

Nominal and total volume

Nominal volume is the quantity the bottle is designed for under normal filling conditions. Total volume to the brim is the physical capacity up to the neck and is slightly larger. The difference between them is a reserve for the closure and for expansion of the contents with changes in temperature. The bottle should therefore be filled to the nominal volume, not to the brim.

What to know before filling

Before the first filling, wash both the bottle and cap with warm water and a cleaning agent, rinse thoroughly, and disinfect with isopropyl alcohol or ethanol. Leave them to dry completely. Residual water in the container unnecessarily strains the product's preservation.

Plastic should not be sterilised by boiling or in an oven. It is safer to fill the contents once cooled. We recommend testing hot filling on a single unit first.

For contents with a high proportion of essential oils, alcohol or solvents, a compatibility test is recommended beforehand.

On a curved surface, the label adheres best when applied to a dry, degreased bottle.
