Airless bottles are made up of two main parts: an inner chamber and an outer chamber. The inner chamber holds your product, while the outer chamber is made up of an airtight seal. This seal keeps air from getting into the bottle and mixing with what’s inside, so your product stays pure and fresh.When you press down on the pump, it pushes against this seal and creates a vacuum in between them—that’s what draws out your product! The pressure of this vacuum also makes sure no air gets in there either (so no oxidation).Gravity doesn’t play a role in how airless bottles dispense product – so you can hold them in any orientation and still get the same amount of product out. Whether you’re holding it upside-down, sideways, or at any angle, the product will flow out evenly. This makes them very convenient to use, as you don’t have to worry about orienting the bottle in a certain way to get the product out. Submit a Quick Quote Request
