The essential lunch boxes for schools and children should usually have the following characteristics to ensure their safety, practicality, and convenience:
1. Material safety
The preferred materials are 304 and 316 food grade stainless steel or PP, which are corrosion-resistant, high/low temperature resistant, and widely used in the food and medical industry.
The sealing ring should be made of food grade silicone to ensure that the parts in contact with food meet safety standards.
2. Anti drop and durable
Considering that children may not be careful enough, lunch boxes should have a certain level of anti drop ability to ensure they are not easily damaged during use.
The zipper, buckle, handle, and other parts of the lunch box should also be sturdy enough to withstand normal use by children.
3. Moderate capacity
Suggest a capacity of 800ml or more to meet children's daily lunch needs.
The inner compartment can be divided into compartments, making it convenient for children to store meals separately and avoiding cross flavors.
4. Anti scalding design: The outer layer of the plastic lunch box can effectively prevent children from getting scalded, especially in winter or when hot food has just been packed.
5. Easy to clean: The lunch box design should be easy to disassemble and clean to reduce bacterial growth.
6. Insulation performance (if needed): If a child cannot go home for lunch, a lunch box with good insulation effect will be very practical. Usually, it is required to maintain a temperature of 60 ℃ or above for 6 hours to ensure the freshness and safety of food.
7. Leak proof design: Each compartment of the lunch box should be equipped with sealing strips to prevent food from tangling or leaking out, especially when containing foods with excessive sauce or partial flow.
8. Aesthetic appearance: Although appearance is not the primary consideration, a simple and brightly colored lunch box is more likely to be loved by children, increasing their willingness to use it.
In summary, the essential lunch box for schools and children should comprehensively consider the characteristics of material safety, durability against falling, anti scalding design, moderate capacity, easy cleaning, insulation performance (if needed), leak proof design, and aesthetic appearance. By selecting the appropriate lunch box, it is possible to ensure the safety and health of a child's diet.
