The present invention has an object to provide, in a container having packing to be used in an environment which produces the difference in the air pressure inside and outside the container due to air transportation and the like, with a configuration that prevents the containment of a negative pressure inside the container. By means of using packing with superior adhesion provided with minute uneven shapes at one or more places of the packing, a container can be obtained which exhibits airtightness in an environment not having a difference in the air pressure inside and outside the container, and which will not cause containment of a negative pressure inside the container at the time of the ambient air pressure fluctuations, for example during the above-mentioned air transportation and the like. Furthermore, the same effect can be obtained even if a minute uneven part is provided at one or more places on the surface of the container main body or the cover that makes contact with the packing.
