The proportion of the elderly population will be higher than the younger population in the future. The elderly need to prepare to live an independent life. In the community, there is an institution where the elderly is taken care of by different group of elderly. Everyday meals are prepared by old people for some others who need to be taken care of. Since their health condition varies, it is difficult to provide nutrient necessary for each one. Nutritional boxes allows meal providers to tell the seniors about the proportion of nutrients, including carbohydrate, protein, and vegetables by pressing the concave and convex dots on the cover. The function of these concave and convex dots on the cover enables seniors to choose the right nutritious lunch box for them by touching the number of dots, considering the "vision loss problem in the elderly". Those who suffer from diabetes can choose a lunch box with fewer dots indicating starchy foods, and enjoy their meal with no concerns.
