Rounded Clear Plastic Bottle, Type B, Golden Pump, 300 ml

A plastic bottle with a pump, 300 ml, is used for filling liquid and semi-liquid cosmetic products that are dispensed by pressing: liquid hand soaps, shower gels, shampoos, conditioners, body lotions or lighter facial emulsions. Clear PET shows the contents and how much product is left in the bottle, which you will appreciate with coloured products or with samples for customers. The black and gold pump with a 24/410 neck finish fits the bottle tightly and dispenses approximately 1 ml of product with one press. It is therefore suitable for products where a measured dose matters and the contents should not come into contact with hands.

The set is declared suitable for contact with cosmetics, and the declaration of conformity for both the bottle and the pump is provided with the product. The set is not intended for food.

What the set is suitable for

• Rinse-off cosmetics – liquid soap, shower gel, shampoo or conditioner. The pump works even with a wet hand, and a plastic bottle will not break if dropped in the bathroom.
• Body and facial emulsions – body lotions and lighter emulsions flow through the pump without problems. For thick creams and butters we recommend a trial, as the pump may not draw up thick textures.
• Facial cleansing products – micellar waters, cleansing gels and milks, where one dose covers one use.
• Oil-based products – massage and body oils. The pump measures them more precisely than pouring from the neck. Test recipes with a high proportion of essential oils in a single bottle first.

Nominal and total volume

The nominal volume of 300 ml is the amount the bottle is designed for in normal filling. Physically, the space up to the neck is larger. The difference provides a reserve for the tube and body of the pump, which take up part of the volume once screwed on, and for the expansion of the contents with temperature changes. The bottle should therefore be filled to the nominal volume, never to the brim, otherwise the product will be forced out through the thread after the pump is fitted.

Working with the pump

The pump tube should reach just above the bottom of the bottle. If it bends after fitting or rests against the bottom, shorten it with an angled cut using a sharp knife so that it also draws up the rest of the contents. After filling, tighten the pump firmly and press it several times until the product reaches the head. The first two to three doses are usually just air.

A dose of 1 ml per press suits most liquid products. For products where more is used, for example shampoo for long hair, allow for several presses and state this in the instructions. A very thick product is drawn up slowly or not at all by the pump. In that case, adjust the viscosity of the recipe or choose a different closure.

Good to know

Before the first filling, wash the bottle and the pump, disinfect them with isopropyl alcohol or ethanol and leave them to dry completely. Pump some disinfectant solution through the pump and then clean water, so that the tube and the mechanism are rinsed as well.

Do not expose the packaging to aggressive chemicals. Check compatibility with the finished formulation, not only with individual ingredients, especially for recipes with a higher proportion of alcohol or concentrated essential oils. Protect the bottle from heat, and always let hot phases cool to room temperature before filling.

The set can be reused. Once empty, simply wash and disinfect it in the same way as before the first filling. With each new product, flush the pump thoroughly, as residues of the previous contents remain in the tube.

Closures with the same neck type, that is the 24/410 neck finish, and other ready-made combinations of bottle and closure can be found in the Handymade range. For your own combination, we recommend checking the tightness, dispensing and behaviour of the packaging with the specific formulation.

The bottle is made of PET, which belongs in plastic waste. The pump combines plastics with metal parts; separate it from the bottle before disposal.
