Plastic cap, 24/410, matte white flip-top

A plastic flip-top cap with 24/410 thread seals the bottle and dispenses from it at the same time. The hinged lid flips open with a thumb, the contents flow through a small opening, and once snapped shut the bottle is closed again. The cap does not need to be unscrewed each time.

It is particularly suited to products used in the shower or at the sink and opened with one, often wet hand. The matte white surface is neutral, works with both clear and coloured bottles, and does not distract from the label.

How a flip-top dispenses

The cap has no pump or other mechanism; the contents come out by gravity or by squeezing the bottle. This determines which bottle type and which product consistency it works best with:

• Soft plastic bottle – the contents are squeezed out by pressing the bottle, so the dose can be controlled well even with thicker gels and lotions.
• Rigid or glass bottle – the contents only flow when the bottle is tilted, so this combination works best with thinner liquids such as oils or watery liquid soaps.
• Product consistency – liquid to medium-thick products dispense best. Very thick creams and butters will not pass through the opening. Water-thin liquids flow quickly; for those, a spray dispenser is more accurate.

Suitable for products such as

• Hair care – shampoos and conditioners that can be opened with one hand.
• Shower gels and liquid soaps – the small opening dispenses more economically than an open bottle neck.
• Body lotions and light emulsions – especially in soft bottles from which they can be squeezed out.
• Body and massage oils – the oil flows in a thin stream and the bottle neck stays cleaner.

Good to know

The designation 24/410 specifies which neck the cap fits: the first number is the neck diameter in millimetres, the second is the thread type. Bottles with a 24/410 neck and ready-made bottle-and-closure combinations are available from Handymade. With a custom combination, we recommend verifying the seal, dispensing behaviour, and packaging performance with the specific formulation.

Filling the bottle: the bottle is filled to the nominal volume, meaning the volume it is designed for under standard filling conditions, not all the way to the top of the neck. The difference from the total volume is a reserve for the closure and for expansion of the contents with temperature changes. An overfilled bottle may push contents into the cap when heated.

The cap is suitable for contact with cosmetic products; the declaration is stated in the product parameters. It can be reused as long as the lid snaps shut firmly and the hinge is undamaged. At end of life, it is sorted as plastic.
