Material Composition | Long-term food storage, hygiene-sensitive environments | 18/8 stainless steel (ASTM A240) (Resists corrosion 3x longer than 18/0 steel) ▲ Industry Standard: 18/0 | ▲ Superior durability and hygiene ▲▲ Advanced: 18/10 (food-grade, 50% thinner walls) | Base model may show minor scratches over time; Advanced has higher cost |
Thermal Insulation | Hot/cold food transport (picnics, commutes) | 12-hour temperature retention (ISO 22442) (Keeps food hot/cold twice as long as glass containers) ▲▲ Industry Standard: 8h | ▲▲ Maintains freshness for full workdays; Advanced: 24h retention ▲▲▲ | Heavier than non-insulated containers; requires pre-heating/pre-chilling |
Capacity | Family meals, group servings | 6L (ISO 780) (Fits 3-4 adult portions) ▲ Industry Standard: 5L | ▲ Accommodates large portions; Advanced: 8L ▲▲ (Serves 6+ people) | Base model may feel bulky for solo use; Advanced adds 30% weight |
Compartment Design | Meal prep, portion control | Triple compartments (ISO 780) (Separates 3 food types) ▲ Industry Standard: 2 | ▲ Organizes meals without mixing flavors; Advanced: 4-tier ▲▲ (Adds dessert/dressing section) | More compartments = harder to clean; Advanced has smaller individual spaces |
Portability | Commuting, outdoor activities | Ergonomic handle + 800g weight (ISO 711) (Balanced grip reduces strain) ▲ Industry Standard: 1kg | ▲ Lighter than competitors; Advanced: 600g ▲▲ (Foldable handle for storage) | Base handle may loosen over time; Advanced requires assembly |
Leak-Proof Mechanism | Travel, spill-sensitive scenarios | Pressure-seal lid (IP67 rated) (Withstands 1m water submersion) ▲ Industry Standard: IP54 | ▲ Prevents leaks during transport; Advanced: IP68 ▲▲ (Submersible up to 3m) | Base requires manual alignment; Advanced lid is 50% heavier |
