1. Technical barriers and preservation principles
Fully sealed antioxidant system: Spring + piston vacuum design is adopted to form a negative pressure environment in the bottle to ensure that the contents are 0 air contact.
Aseptic barrier technology: medical-grade PP liner + ABS shell, through testing, blocking ultraviolet/microorganism penetration, and extending the shelf life of the product after opening.
Precise dosage control: Patented press valve core achieves small error, suitable for high-priced essence/peptide products, reducing waste caused by excessive use.
2. Differentiated market positioning
High-end skin care line standard: matching anti-aging essence, VC derivatives, sterile formulas and other high-performance products that are sensitive to oxidation.
Sustainable packaging solutions: support safe repeated filling and reduce carbon emissions.
3. User experience upgrade points
Anti-backflow design: one-way valve prevents the contents from being sucked back to avoid cross contamination.
Blind operation optimization: 30° tilt angle of the bottle + tactile convex dot design to improve the friendliness of visually impaired users.
Residual liquid rate: bottom flat cut structure + flexible piston to reduce lotion residue.
