PURPOSE:To keep sealing of containers for commercial sealed food independently in various sizes, for example, half of the container for commercial sealed food, by a method wherein a jointing and separating means is provided so that two or more containers for commercial sealed food are jointed with each other and jointed ones can be separated again. CONSTITUTION:On the outer 3 of an upper rim 2 of a container 1 for commercial sealed food, an external thread is provided, and on the inside 5 of a lower rim 4, an internal thread is provided so that the two or more containers can be jointed. A relatively small amount of commercial sealed food is put in one container. Reduction of the amount of food taken out at one time enables fresh and delicious food which is not oxidized to be again eaten at the next time, reducing wasted food. During display or storage of the food, the containers can be neatly arranged, enabling efficient use of spaces. It is also easier on the case of carrying a plurality of containers. |
