Clear round plastic bottle, matte white flip-top, 300 ml

A transparent round PET bottle with a capacity of 300 ml and a matte white flip-top cap is a ready-to-use set for liquid and semi-liquid products dispensed through a small opening: shampoos, shower gels, liquid soaps, conditioners, body lotions, or massage oils.

PET is lightweight and shatter-resistant, making the bottle suitable for use in the shower, bathroom, and on the go — anywhere glass might break. The clear wall lets you see how much product remains. The flip-top opens with one hand and its hinged part stays attached to the cap so it cannot be lost.

The set is declared as suitable for contact with cosmetic products. It is not intended for food use.

Which products is the set suitable for

• Shampoos, shower gels, and liquid soaps – medium-viscosity surfactant products flow through the opening evenly and the dose is easy to estimate.
• Conditioners and body lotions – thinner emulsions are a good fit. Thick creams and butters will not pass through the opening; those belong in a jar.
• Massage and body oils – oil is dispensed in small amounts directly into the palm.
• Coloured and layered products – the clear wall shows the colour, pearlescence, or two-phase content. It will equally reveal any colour change or cloudiness.

Very thin water-based products flow out of the opening quickly and the dose is difficult to control. A different closure type is more practical for these.

Nominal and total volume

Nominal volume is the quantity the bottle is designed for under normal filling conditions. Total volume is the physical capacity up to the rim of the neck and is slightly larger. The difference serves as a buffer for the cap and for expansion of the contents when the temperature changes. The air space above the product also makes it easier to shake.

Preparation and filling

Before the first fill, it is recommended to wash the bottle and cap with lukewarm water and a small amount of detergent, then rinse thoroughly. They are then rinsed or sprayed with isopropyl alcohol or ethanol and left to dry completely. With a flip-top cap, it is worth checking the dispensing opening and the area under the hinged part, as water tends to collect there the longest.

The bottle is filled using a funnel or a beaker with a spout. The cap is tightened by hand with moderate force. Overtightening may strip the thread and cause the cap to lose its seal.

Good to know

• Light – clear PET does not protect the contents from light. Products containing vegetable oils, extracts, vitamins, or natural colourants should be kept out of direct sunlight, or a dark packaging option should be chosen.
• Essential oils and solvents – concentrated essential oils, fragrance compositions, and organic solvents can damage the plastic. The bottle is not intended for storing these.
• Labelling – self-adhesive labels adhere best to a dry and degreased surface, ideally before filling. The bottle dimensions needed for label design are listed in the specifications.
• Other closures – closures with the same neck type (stated in the specifications) and further ready-to-use combinations are available in the Handymade range. For custom combinations, we recommend testing the seal, dispensing performance, and container behaviour with the specific formulation.
• Recycling – both the bottle and the cap are made of plastic and should be placed in sorted plastic waste collection once empty.
