The present invention relates to a container (1) comprising: - a body (2) - a pusher (5) movable with respect to said body (2) between an initial position and an end-of-use position - a locker (7) located on said pusher (5) and forming an abutment so as to be able to abut against said body (2) between said initial position and end-of-use position, - locking means (9, 9b, 8, 5, 4a, 11, 12, 15, 29, 29a, 30a) capable of, temporarily, lock said locker (7) on said pusher (5), in the proximal direction relative to said pusher (5), so as to define a locker locking position and, when said pusher (5) abuts against said body (2) via said locker (7), define a pusher locking position, - unlocking means (9, 9a 10, 29, 31, 13, 16, 17, 31) designed so that their triggering causes the release of said locking means so as to allow i) said locker (7) to be displaced proximally relative to said pusher (5) and ii) said pusher (5) to be moved past said pusher locking position toward said end-of-use position, which container (1) is characterized in that said unlocking means are designed to be automatically triggered so as to release said locking means in said pusher locking position upon distal pressure exerted on said pusher (5).
