The 50ml volume is the global retail benchmark for “full-size” entry-level luxury fragrances. However, at this capacity, glass distribution consistency is critical to prevent thermal shock and “shoulder-weakness” during automated capping. At STDGLASS, our Model XB475 is produced through high-precision blow-and-blow molding to ensure uniform wall thickness and a reinforced base.
For brands moving from artisanal production to consistent bulk retail, the XB475 provides the structural integrity required for high-speed conveyor stability and global distribution.
I. Technical Specifications & Mechanical Calibrations
Every unit of the XB475 series undergoes strict annealing to eliminate internal stress, ensuring the vessel can withstand the mechanical pressures of vacuum filling and crimp-neck sealing.
- Model Identification: XB475
- Nominal Capacity: 50ml
- Caliber: 15mm Bayonet (Standard Crimp Neck)
- Vessel Dimensions: 7.7cm (Height) | 4.1cm (Width)
- Total Profile Height: 10cm (Including standard actuator and cap)
- Glass Purity: High-Clarity Flint (No detectable green/blue hue)
- Manufacturing Tolerance: Strict ±0.15mm on neck diameter to prevent pump leakage.
II. The FEA Standard: Solving the “Pump-Fit” Crisis
One of the primary failure points in fragrance packaging is the interface between the glass neck and the atomizer. A variance of just 0.3mm can lead to catastrophic leakage or “pump wobble.”
We mitigate this by adhering to the 15mm bayonet (FEA 15) standard. This ensures that our 50ml vessels are 100% compatible with premium actuators from world-class suppliers like Aptar or Coster. The crisp rim finish allows for a hermetic seal, protecting your fragrance formulations from oxygen-induced oxidation.
