Airless Bottle HS-013A

HS-013A Premium Plastic Airless Pump Bottle Stylish Design Refillable Lotion Bottle Recyclable PP AS Packaging 15ml 30ml 50ml is a packaging container that uses the principle of air pressure difference to achieve complete access to the contents. It is commonly used in creams, essences, sunscreens and other cream cosmetics.

1. Core structure and working principle
Main components:
Bottle body: usually cylindrical, made of PET, PP, and glass.
Vacuum pump: core component, including piston, spring, and base.
Pump head: push-type design, part of which can be rotated and locked to prevent accidental touch.
Inner liner: soft material that isolates air and shrinks as the contents decrease.
Working principle: When the pump head is pressed, the air pressure pushes the piston up and the contents are squeezed out through the catheter; after release, the spring resets, the inner liner shrinks to form a vacuum to prevent product reflux or oxidation.

2. Industry applications and advantages
Applicable products: high-value, easily oxidized cosmetics (such as VC essence, anti-aging cream, sterile formula).
Core advantages: vacuum isolates air and bacteria, prolongs the life of active ingredients, and the utilization rate of contents reaches more than 95%, reducing waste, accurately controlling the amount, and avoiding hand contact contamination.

3. Market trends and innovations
Replaceable inner core design, bio-based plastics, recyclable structure, microporous pump head (adaptable to different viscosities), display of remaining amount.

4. Common problems and solutions
Leakage: Check the spring elasticity or the sealing of the inner liner.
Poor pressing: It may be due to the paste being too thick, and the diameter of the catheter needs to be adjusted.
