The present invention regards a container comprising a support having a base, a lateral wall and an abutment flap emerging from the lateral wall. The container comprises a closure system movable between a closed condition and open condition, a first coupling portion carried by the closure system and a second coupling portion defined on the abutment flap. The first coupling portion is movable between a first operating position in which it is disengaged from the second coupling portion and a second operating position in which it is engaged with said second coupling portion. The first coupling portion comprises a central body from which a tab emerges that is engageable with the second coupling portion; the first coupling portion defines a removable portion configured for being separated from the closure system following a first opening of the container following an engagement between said first and second coupling portions.
