Abstract

Disclosed is a box that includes a base and a lid connected by a hinge including at least one hinge portion connected to the lid by a frangible connection configured to break during the first opening of the lid. The box includes a tongue extending from the lid and beyond the articulation axis, such that when the box is closed, the tongue extends toward the outside of the box from the lid while protruding relative to the hinge beyond the articulation axis, pulling on the tongue making it possible to open the lid by breaking each frangible connection, a lid portion of each hinge part remaining secured to the base and separate from the lid, in the protruding state.
