Child-proof container comprising: - a storage defining a compartment and having a lateral wall defining a passage opening delimited by a free edge, said passage opening being configured for placing the compartment in communication with the outside environment, - a closure system movable with respect to the storage at least between: ∘ a closed condition where the closure system prevents the communication between the compartment and the outside environment, ∘ an open condition where the closure system allows the communication between the compartment and the outside environment, - at least one first coupling portion carried by the closure system, - at least one second coupling portion carried by the storage and configured for cooperating with said first coupling portion, wherein the first and the second coupling portions (12, 13) are configured for being engaged with each other in the closed condition of the container to define a locking condition where said first and second coupling portions (12, 13) prevent the closure system from passing from the closed condition to the open condition, wherein the second coupling portion comprises at least one tab outside the compartment and defining at least one undercut configured for engaging the first coupling portion of the closure system to define said locking condition, wherein the container comprises at least one spacer at least partly interposed between the tab of the second coupling portion and the lateral wall of the storage, characterized by the fact that the tab of the second coupling portion, in the closed condition, is movable at least between: - a first operative position where the tab is configured for engaging the first coupling portion to define said locking condition, - a second operative position where the tab is configured for disengaging the first coupling portion to allow the passage of the closure system from the closed condition to the open condition. - a storage defining a compartment and having a lateral wall defining a passage opening delimited by a free edge, said passage opening being configured for placing the compartment in communication with the outside environment, - a closure system movable with respect to the storage at least between: ∘ a closed condition where the closure system prevents the communication between the compartment and the outside environment, ∘ an open condition where the closure system allows the communication between the compartment and the outside environment, ∘ a closed condition where the closure system prevents the communication between the compartment and the outside environment, ∘ an open condition where the closure system allows the communication between the compartment and the outside environment, - at least one first coupling portion carried by the closure system, - at least one second coupling portion carried by the storage and configured for cooperating with said first coupling portion, wherein the first and the second coupling portions (12, 13) are configured for being engaged with each other in the closed condition of the container to define a locking condition where said first and second coupling portions (12, 13) prevent the closure system from passing from the closed condition to the open condition, wherein the second coupling portion comprises at least one tab outside the compartment and defining at least one undercut configured for engaging the first coupling portion of the closure system to define said locking condition, wherein the container comprises at least one spacer at least partly interposed between the tab of the second coupling portion and the lateral wall of the storage, characterized by the fact that the tab of the second coupling portion, in the closed condition, is movable at least between: - a first operative position where the tab is configured for engaging the first coupling portion to define said locking condition, - a second operative position where the tab is configured for disengaging the first coupling portion to allow the passage of the closure system from the closed condition to the open condition. - a first operative position where the tab is configured for engaging the first coupling portion to define said locking condition, - a second operative position where the tab is configured for disengaging the first coupling portion to allow the passage of the closure system from the closed condition to the open condition.
