PROBLEM TO BE SOLVED: To provide an easy-recoverable container of which transporting cost can be remarkably reduced and provide an empty container recovering system in which the empty can be reproduced and utilized at a low cost. SOLUTION: This container has a groove 1 which is continuous in a substantial perpendicular direction in respect to a longitudinal direction of the container over a substantial entire side surface of the container in such a way that the container having empty liquid contents therein may easily be press collapsed with a slight longitudinal pressure. This recovering system includes a step for recovering the press-collapsed container.
