Standard Four-Compartment Meal Layout

Built for student and office lunch markets in Japan, South Korea and North America, this box is designed specifically for regular midday meal carry. The four sections are proportioned to match a standard full meal, with dedicated spaces for staple food, main dish, side dish and a small serving or soup. The balanced layout supports sensible dietary matching, and the physical separation prevents flavor transfer between different dishes.

Airtight Freshness Lock Design

A food-grade sealing gasket sits inside the lid to create an enclosed space when closed. The seal locks in food freshness and temperature, and prevents soup or sauce spills during transport for safer carrying to school or work. The box is calibrated for standard adult lunch portions, targeting campus and office midday meal carry.

Rounded Corner Easy-Clean Build

All compartment edges use smooth rounded transitions with no sharp corners that trap food debris and become hard to clean over time. The inner wall carries an easy-clean antibacterial coating that lifts away lunch grease, sauce and food residue with plain water rinsing, so simple washing restores the unit to clean condition. Long-term use leaves no buildup of grease or persistent odors.
