Child-proof container and process of making the same

A child-proof container comprising:

• a storage defining a compartment for housing at least one product, the storage having lateral walls defining at least one passage opening delimited by an edge, said passage opening being configured to put the compartment in communication with the external environment,
• at least one closure system relatively movable with respect to the storage at least between:
• a closure condition where the closure system interdicts communication between the compartment of the storage and the external environment, and
• an open condition where the closure system allows communication between the compartment and the external environment,
• at least one first coupling portion carried by the closure system, and
• at least one second coupling portion carried by the storage,
• wherein the first and second coupling portions, in the closure condition, are configured to engage with each other to define a locking condition of the container where said first and second coupling portions prevent the closure system from switching from the closure condition to the open condition,
• wherein the second coupling portion comprises:
• at least one first panel comprising at least one through opening at least partially delimited by a gripping edge, and
• at least one second panel facing the first panel,
• wherein the first panel is interposed between said second panel and a lateral wall of the lateral walls of the storage directly carrying the second coupling portion,
• wherein the second panel is arranged at the through opening of the first panel to define, in cooperation with said through opening of the first panel, a blind seat configured to house, during the closure condition of the closure system, at least part of the first coupling portion,
• wherein the first coupling portion comprises a first tab and a second tab in sheet material and the first tab and the second tab at least partially overlapping each other,
• wherein at least one of the first tab and second tab, in the closure condition, is arranged at least partially in the blind seat and is engaged to the gripping edge of the first panel of the second coupling portion to define the locking condition,
• wherein the second coupling portion is at least partially movable relative to the storage at least between a blocking position where the second coupling portion is configured to engage the first coupling portion,
• a release position where the second coupling portion is configured to disengage the first coupling portion to allow the closure system to switch from the closure condition to the open condition, and
• wherein the gripping edge, in the blocking position, has a distance from the lateral wall of the storage directly carrying the second coupling portion that is less than a distance between said gripping edge and the lateral wall when the second coupling portion is in the release position.
