A manufacturing method of a meal box capable of extending preservation time at normal temperature is provided, comprising the steps of: cleaning a container box filling cooked rice, meat, fish, vegetable and other foods in the container box vacuum-capping the container box performing a washing process and a high-temperature high-pressure sterilization process to the vacuuming-capped container box and allowing the vacuuming-capped container box to be preserved at normal temperature after the vacuuming-capped container box is cooled. The container box comprises one or more than one containing region, and each containing region is provided with a corresponding seal cap. In the vacuum-capping process, the corresponding seal caps are respectively connected above the containing regions for sealing the containing regions, so that the purpose of extending preservation time of the meal box at normal temperature can be attained. Accordingly, children can have fresh food through the meal box in ordinary time, typhoon day, long journey, or at home in winter or summer vacation when their parents have no time for food preparation. It is understood that the meal box manufacturing method is characterized with novelty, inventiveness and industrial applicability.本發明係提供一種常溫可延長保存時間的便當製造方法,係將容器盒先經清洗後,再將米飯、肉類、魚、菜及其他食物填充入該容器盒內,再將容器盒之封蓋進行真空封蓋,後再將完成真空封蓋之容器盒再進行沖洗及高溫高壓滅菌程序,待其冷却即可於常溫長時間保存,該容器盒包括有一個或一個以上之容置區,於每一容置區均有其對應之封蓋,而於真空封蓋時分別將每一對應之封蓋結合於每一容置區上方,將其密封進而使便當達常溫可延長保存時間者,而可使平時、颱風天、長途旅行或於寒暑假兒童在家中且父母無法準備食物時,均可吃到新鮮的便當,為一甚具新穎性、進步性及可供產業上應用之發明。(1)‧‧‧容器盒(11)(12)‧‧‧容置區(111)(121)‧‧‧封蓋(14)‧‧‧米飯(15)‧‧‧肉類(16)‧‧‧菜(17)‧‧‧魚
