Airless
Hi, I see that there are some airless containers available. I have no idea how these work, could some kind person explain, and what’s the customer experience like? I’m thinking of our high end vitamin C product.

OK. In a traditional dispenser, the container is rigid, the pump is set up so that a vacuum is created in the dispensing tube, then atmospheric air presses down on the bulk, and the product is extruded through the tube.
In an airless dispenser, the bottom is not the same piece as the sides. Instead, it acts as a piston, so that when the pump creates a vacuum in the tube, atmospheric pressure moves the piston up, allowing bulk to dispense without exposing it to more air.
I know I haven’t explained this very well, sorry.

Oh. So there’s a plastic base, rigid I imagine, that progressively moves up and into the cylindrical body, as more product is dispensed? Is that it? The seal must work pretty well.

They’re really nice we use them in quite a few products actually.

I imagine you can use a much lower level of preservative?

Yea just checked through the database, looks like we’re using around half the usual levels. Some a bit less, some a bit more. Most of our products in the airless containers are gels.

I’ve highlighted the pistons that are visible in the clear packaging. You can see that they have two sealing surfaces, one top and one bottom. The extra cost of the packaging is probably offset by the lower cost of preservatives and anti-oxidants required.

Maybe this explains it better

Very clear, thank you. Assuming our efforts to locate a permanent supply are successful, I think we’ll move several products to this style.
