White plastic airless bottle 200 mlBiela plastová airless fľaška 200 mlAirless bottle, white plastic 200 ml is a complete bottle-and-cap set for dispensing creams, serums and emulsions without exposure to air. The contents are pushed out by a pump without a dip tube: with each press the base of the bottle moves upward and releases one dose, while no air enters the remaining product. It is therefore especially suited to formulations that are sensitive to oxidation and that the customer should dispense cleanly, without scooping with fingers.
The white opaque plastic also dims light and protects the contents from its effects as well. The nominal volume of 200 ml is a format for body lotions, larger packs of face creams or salon products that are used up in portions over a longer period. The cap in the set covers the pump head and prevents it from being pressed accidentally during transport or in a cosmetics bag.
A standard pump bottle draws the contents up through a tube and lets air into the container with every press. An airless bottle works differently: inside it has a movable base (piston) that with each press moves closer to the pump and pushes the contents out. The product thus stays sealed throughout use, is not aerated, and almost all of the contents can be pressed out regardless of how you hold the bottle.
This principle leads to the main advantage for the formulator: limited contact with air slows the oxidation of vegetable oils, vitamins and antioxidants, and finger-free dispensing reduces the risk of introducing microorganisms into the product. However, airless packaging does not replace preservation; it only eases the stress the product is exposed to during use.
It performs best with formulations of creamy to milky consistency that the piston can reliably push out:
It is less suitable for very thin water-based products (toners, hydrosols), which are better dispensed with a sprayer or dropper, and for very thick or solid masses that the pump will not move.
Before the first filling we recommend you wash and disinfect both the bottle and the cap with isopropyl alcohol or ethanol and let them dry completely. The airless bottle is filled from the top after unscrewing the pump head. Fill slowly and without trapping air bubbles, because air trapped under the pump may cause the first doses not to come out.
When filling, follow the nominal volume, not the rim. The nominal volume is the volume the packaging is designed for under normal filling; the total volume up to the neck is larger and the difference provides a reserve for the pump mechanism and for the expansion of the contents with temperature changes. Overfilling may cause the product to be squeezed out when closing and the piston to malfunction.
After filling and screwing on, press the pump several times empty until the system “starts up” and the first full dose comes out. This is normal behavior of airless packaging, not a defect.
Always put the cap on after dispensing: it protects the head from dirt and from unwanted pressing. The packaging is intended for a single filling; reuse is possible only after thorough cleaning and returning the piston to its starting position, which is not practical with every formulation.
The approximate dose size of the pump is about 1.2 ml, which corresponds to a usual single dose of body lotion or a larger face cream. For products where a smaller amount is used (eye creams, concentrated serums), take this into account in the instructions for use.
The consistency of the product determines how smoothly dispensing will work. Medium-viscosity emulsions come out evenly; with very thick masses we recommend checking whether the pump pushes out the whole dose, and with very thin ones whether the product leaks out after pressing.
It is advisable to test compatibility with the formulation. For formulations with a high proportion of essential oils or solvents we recommend a stability test directly in this packaging. The set is not approved for contact with food, so it is not intended for homemade oils, syrups or other food products.
Products that release gas (for example freshly fermented or effervescent ingredients) do not belong in an airless bottle, nor do masses with larger solid particles that would block the pump valve.
Recycling: the packaging is made of plastic and, once empty, belongs in sorted plastic waste. Caps with the same neck type and ready-made packaging combinations can be found in the Handymade range; for your own combination we recommend checking the tightness, dispensing and behavior of the packaging with the specific formulation.
