Protection and storage bag with roll-up closure

Abstract

A protection and storage bag includes a main opening configured to be closed by rolling up, the opening defining an opening perimeter. The bag further includes a flexible or hinged anti-theft member having a first free end, a central part linked to a portion of the opening perimeter and a second free end, the two free ends of the anti-theft member being configured to cooperate with a locking system in order to lock the anti-theft member in a closed position; an anti-rotation system configured to prevent any relative rotation between the anti-theft member and the portion of the opening perimeter; and an anti-turn system for preventing the anti-theft member from being turned by twisting when the bag is closed by rolling up and locked by the locking system.
