Customized Plastic Acrylic Airless Jar with PP Material and Silkscreen Print for Cosmetic Lotion and Face Cream

Of course! An airless jar (or airless bottle) is a premium type of packaging that is highly regarded in the cosmetics and skincare industry for its ability to protect and preserve sensitive formulations.

Here’s a detailed breakdown of everything you need to know.

What is an Airless Jar?

An airless jar is a dispensing system that protects its contents from exposure to air, light, and bacteria. Unlike a traditional jar where you dip your fingers in, or a standard pump that draws air into the bottle, an airless system uses a mechanical mechanism to push the product out without letting any external elements in.

How Does an Airless Jar Work? (The Magic Mechanism)

It seems like magic, but it's clever engineering. When you look at an airless jar, you're actually looking at an outer casing and an inner, collapsible bag or piston.

1. The Components:

   • Outer Casing: The rigid, decorative shell you see.

   • Inner Bag/Piston: A flexible, collapsible pouch inside that holds the product, sitting on top of a flat piston (disc).

   • Dispenser Head: A pump actuator on top.

   • Piston Platform: A disc at the bottom that moves upwards.

2. The Dispensing Process:

   • When you press the pump, it creates a vacuum.

   • This vacuum causes the piston at the bottom to move upwards.

   • The upward movement of the piston pushes the entire inner bag upwards, compressing it and forcing the product out through the pump.

   • No air is ever drawn back into the product chamber. The space left by the dispensed product is taken up by the rising piston, preventing air from entering.

Visualize it like a syringe: The piston is the plunger, and the product is the liquid inside. When you push the plunger, the liquid comes out the top, and no air gets in.
