A lunch box is a portable container used for carrying food to be eaten during lunchtime, typically while away from home or work. Lunch boxes come in various shapes, sizes, and materials, such as plastic, metal, fabric, or insulated materials.Traditional lunch boxes often consist of a rectangular or square-shaped container with a lid that can be opened and closed. Some lunch boxes may have multiple compartments or sections to keep different foods separate and prevent them from getting mixed or spilled. Insulated lunch boxes can keep food cold or hot for an extended period, making them ideal for carrying perishable items.
Modern lunch boxes often feature additional accessories like utensils, napkins, or reusable containers, which promote environmentally friendly practices. Some lunch boxes even come with built-in ice packs or heating elements to keep food at the desired temperature.
