A New Lunch Box That Can Cool Food to Reduce Risk of Summer Food Poisoning

Fluke Forest Co., Ltd. is currently conducting a crowdfunding campaign for the 'HAPEL Heating/Cooling Lunch Box,' a next-generation lunch box that uses Peltier elements to 'both heat and cool,' on the crowdfunding site 'machi-ya by CAMPFIRE.'

In recent years, with rising temperatures in summer, the risk of food poisoning in packed lunches has gained attention. A major challenge is that if cooked rice or side dishes are packed while still hot without being fully cooled, the lid traps heat and moisture inside, creating an environment where bacteria can easily multiply.

The HAPEL Heating/Cooling Lunch Box proposes a new approach to this summer lunch situation: a 'lunch box that can cool.'

■ An Unprecedented Lunch Box, Like a Refrigerator

Pack while hot and carry in 'Cooling Mode'

In typical lunch preparation, food must be cooled down sufficiently before closing the lid, and additionally, ice packs or insulated bags are needed to prevent temperature increases.

However, the HAPEL Heating/Cooling Lunch Box is equipped with a cooling function using Peltier elements. It allows users to carry meals packed while hot while managing their temperature in 'Cooling Mode.'

Furthermore, in the heat of summer, users can utilize 'Cooling Mode' to maintain the interior of the lunch box at a lower temperature, supporting food temperature management and making the summer lunch environment more comfortable.

■ Enjoy Fresh Taste by Reheating When Eating

Switch to 'Heating Mode' just before eating

The feature of the HAPEL Heating/Cooling Lunch Box is that it doesn't stop at just 'cooling.'

By switching from 'Cooling Mode' to 'Heating Mode' before lunch, users can eat their meal warm again.

Carry it safely while cold, and enjoy it warm the moment you eat—it is an unprecedented 'heating/cooling switchable lunch box.'

■ Heating/Cooling Compatible Lunch Box Using Peltier Elements

Heating/cooling system utilizing Peltier technology

This product uses 'Peltier elements,' which can switch between heating and cooling depending on the direction of the electric current.

While Peltier technology is used in cooling equipment, it requires high technical capability in terms of durability and power consumption to be mounted in a lunch box size powered by a battery.

By leveraging the technology of a specialized Peltier element manufacturer, the HAPEL Heating/Cooling Lunch Box has been commercialized as a small, portable lunch box.

■ Enjoy Delicious Lunch Even Without Microwaves or Refrigerators

Supports mobile battery power supply

The main unit has a built-in battery and can be used when out for commuting, school, or outdoor activities.

Furthermore, as it supports USB PD power supply, it can maintain temperature for longer periods by using a mobile battery or USB power source in combination.

'Temperature-manageable' peace of mind for the coming season

A new common sense of 'being able to cool' for summer lunches

In recent years of extreme heat, lunch boxes are now viewed as requiring 'temperature management' in addition to 'deliciousness.'

The HAPEL Heating/Cooling Lunch Box proposes a new lunch style where users can enjoy warm and cold dishes at appropriate temperatures while being mindful of food poisoning prevention in summer.
