Package comprising means for keeping an object in place

A package comprising:

• a case defining a cavity, the cavity being delimited by inner faces;
• means for obturating the cavity comprising a lid, the obturation means being movably mounted on the case, between an open position allowing access to the cavity and a closed position obturating access to the cavity;
• retaining means comprising a plate intended to press an object against one of the inner faces of the case, called support face, and a mechanism for coupling the plate to the lid and to the case;
• wherein the coupling mechanism comprises:
• means for movably driving the plate during an opening or a closing of the obturation means, the drive means being designed to drive the plate in the direction of the lid and allow access to the cavity during passage of the obturation means from their closed position to their open position;
• means for elastically returning the plate in a position pressed against the support face;
• the drive means and the elastic return means being designed to drive together the plate in its position pressed against the support face during passage of the obturation means from their open position to their closed position,
• characterized in that the elastic return means comprise at least one elastic link extending from one end coupled to the plate to another end coupled to an attachment point in the package, and in that the coupling mechanism comprises means for compressing the elastic link between its two ends, the compression means being active in the closed position of the obturation means and inactive apart from this closed position.
