To prevent liquid carried by an item from attaching to another item when a plurality of items are stored into a packing body.

An inside container body 20 which is formed by deep drawing is inserted into an upper opening of an outside container 10 which is formed into a depressed shape by deep drawing. Both the containers are in surface contact with each other along the entire circumferences of ribs 11, 12 formed at the upper ends thereof, respectively. The entire periphery of the rib of the body 20 is in contact with the outer periphery of a film 30. The body 20 and the film are heat-sealed along the superposed outer peripheries and tightly closed. The body 10 is fixed to the body 20 and the film by means of a staple. Thus, tightly closed space is ensured in each of the bodies, and hence liquid seeping out of items stored in each of the bodies is prevented from being transferred to each other. Items stored in the body 10 can be easily separated from the body 20 by removing the body 10.
