Plastic bottle, blue, 24/410, without closure, 200 ml

A lightweight blue PET bottle with a nominal volume of 200 ml and a 24/410 threaded neck, supplied without a closure, designed for liquid and semi-liquid products dispensed repeatedly: tonics, hydrolat mists, micellar waters, shower gels, body lotions, massage oils and liquid soaps. The blue tint gives the contents a uniform appearance and distinguishes it from clear packaging, while the plastic withstands a drop in the bathroom and a journey in a suitcase without risk of breakage.

The bottle is suitable for use with cosmetic products and is also approved for direct food contact. It is therefore also suitable for homemade herbal oils, syrups, infusions or dressings.

Key features

• Low weight and durability – PET is significantly lighter than glass and will not break, reducing shipping costs and making it easier to use in the shower, at the sink or on the go.
• Blue tint – reduces some light transmission and gives the product a uniform appearance without fully concealing the contents; the fill level remains visible under good lighting.
• 24/410 neck – one of the most common neck sizes, so a closure can be selected to suit the dispensing method, from a simple cap to a spray or pump.
• Suitable for cosmetics and food – the packaging meets requirements for contact with both cosmetic products and food; a declaration of conformity is available on the product page.
• Easy recycling – the bottle is made from a single material, PET, and goes into standard plastic waste collection.

Filling and volume

The 200 ml figure is the nominal volume, meaning the quantity the bottle is designed for under normal filling conditions. The total capacity to the top of the neck is somewhat larger. This difference is not a defect but a headspace: it is needed for the dip tube of a pump or spray, the air layer above the fill level, and any expansion of the contents with temperature changes. The bottle should therefore be filled to the nominal volume, not to the neck. For products dispensed with a pump, it is advisable to leave a slightly larger headspace so that nothing is pushed out when the closure is fitted.

Choosing a closure

Closures with the same 24/410 neck finish and ready-made bottle-and-closure combinations are available in the Handymade range. When assembling your own combination, we recommend verifying the seal, dispensing performance and packaging behaviour with the specific formulation, especially for thicker lotions and gel products.

What is good to know

Preparation before filling. Bottles are supplied clean but not sterile. Before filling a cosmetic product for the first time, rinse them, disinfect with isopropyl alcohol or ethanol and leave to dry completely, neck down. Residual water in the packaging would dilute the preservative system and shorten the shelf life of the contents.

Temperature. PET is not intended for hot filling. Allow emulsions, gels and oils to cool before pouring into the bottle; otherwise the wall may deform or turn hazy. The bottle is also not suitable for heating the contents in a water bath.

Essential oils and solvents. PET tolerates standard cosmetic products containing essential oils at typical usage levels. However, undiluted essential oils, perfume compositions at high concentrations, or products with a high proportion of solvents may gradually weaken, soften or discolour the plastic. For such concentrates, glass is more suitable; alternatively, test the packaging behaviour on a sample over several weeks.

Alcohol-based and aqueous products. Tonics, hydrolats, micellar waters and products with a standard alcohol content are a typical use for PET. For high-strength alcoholic extracts, we recommend verifying packaging stability in the same way as for concentrates.

Reuse. The bottle can be reused after washing and disinfection, provided it is not scratched or deformed. When changing the type of fill, for example from an oil to a water-based product, degrease it thoroughly so that residues from the previous contents do not affect the new product.

Labelling. The cylindrical shape without edges makes it easy to apply a label around the full circumference. Standard self-adhesive labels adhere well to PET; for products used in the shower, choose a moisture-resistant label.
