Storage Lunch Bento Box with Lid BPA Free
1. Advanced 360° Collapsible Hinge System for Round Design
Features a patented 360-degree folding mechanism with reinforced silicone hinges distributed evenly around the perimeter, allowing the container to collapse to 1/4 of its original height (vs. standard 1/3) while maintaining structural integrity. The circular design eliminates corner stress points, enabling 5000+ folding cycles without deformation—ideal for frequent use and compact storage.
2. Platinum-Cured Medical-Grade Silicone with Enhanced Flexibility
Utilizes FDA 21 CFR 177.2600 certified platinum-cured silicone specifically formulated for circular containers, providing superior flexibility and shape retention. The material maintains elasticity from -40°C to 250°C, resists cracking at fold points, and features anti-microbial silver-ion technology that inhibits 99.9% of bacterial growth on surfaces.
3. 4-Point Locking System with Pressure-Equalization Valve
Engineered with a reinforced 4-point locking mechanism (evenly spaced around the circular lid) that creates a uniform seal pressure. Integrated one-way silicone valve automatically releases internal pressure during temperature changes while maintaining liquid-tight seal. The circular design ensures even pressure distribution, preventing leaks even when inverted or shaken.
4. Space-Optimized Circular Design with Stackable Features
The circular shape allows for efficient nesting when collapsed (reducing storage space by 75%) and secure stacking when expanded. Features precision-molded interlocking grooves on both lid and base, enabling vertical stacking of up to 6 containers without sliding. The compact circular footprint optimizes refrigerator and cabinet space utilization.
5. Eco-Certified & Commercial-Dishwasher Rated
Third-party certified to replace 600+ single-use plastics annually, with NSF/ANSI 51 certification for food equipment safety. Withstands 3000+ commercial dishwasher cycles at 85°C without degradation. The circular design’s smooth surface resists food residue buildup and is easy to clean with no hard-to-reach corners.
