PROBLEM TO BE SOLVED: To provide a container which ensures that the container body can easily be deformed by substantially the same external force until most of the content is discharged from the container body, so that the amount of the content discharged in the end becomes constant, thereby easily keeping the concentration of the dilution constant at all times.SOLUTION: A container comprises: a bottomed container body 1 accommodating a content; and a lid body 9 for closing an opening section of the container body 1, the container body 1 and the lid body 9 being sealed by an annular seal section formed along a flange of the opening section. The annular seal section has a separation seal section 6S provided in a predetermined position thereof, the separation seal section 6S being separated by an internal pressure rise within the container body 1, caused by deformation of the container body 1 due to application of an external force from a bottom surface 3 of the container body 1. The container further includes in a part of a side wall of the container body 1 a deformation control concavity 16 which gradually tapers down toward the bottom surface 3 side from a rear face side of the flange. |
