A sheet retaining device such as a folder or a binder that incorporates a corner lock for preventing papers from dislodging therefrom. The sheet retaining device has a front cover (102) and a back cover (104). Each of the covers has a top edge (113), a bottom edge (111), an outer edge (109), and an inner edge (115). A first primary flap (116) is connected to the back cover along the outer edge and the bottom edge thereof to form a pocket that is adapted to receive one or more pieces of sheet material. A secondary flap (116) is connected to the back cover along the inner edge and the top edge thereof to form a corner lock adapted to retain corner of sheet material retained in the sleeves. Accordingly, when a piece of sheet material is retained in the pocket, the secondary flap acts as a corner lock on the free corner of the sheet material, tending to retain this free corner and the sheet material in the pocket, even if the sheet retaining device is turned upside down or sideways.

L'invention concerne un dispositif de retenue de feuilles, tel qu'un dossier ou un classeur présentant un coin de retenue empêchant les feuilles de se détacher du dossier ou du classeur. Le dispositif de retenue présente un plat recto et un plat verso. Chacun de ces plats présente un bord supérieur, un bord de base, un bord extérieur et un bord intérieur. Un premier rabat primaire est relié au plat verso le long de son bord extérieur et de son bord de base, de manière à former une poche qui est adaptée pour recevoir un ou plusieurs éléments d'un matériau en feuilles. Un rabat secondaire est relié au plat verso le long de son bord intérieur et de son bord supérieur, de manière à former une retenue de coin adaptée pour maintenir les feuilles retenues dans les pochettes. En conséquence, lorsqu'un élément du matériau en feuilles est maintenue dans la poche, le rabat secondaire agit comme une retenue de coin sur le coin libre du matériau en feuilles, ce qui a tendance à retenir ce coin libre et le matériau en feuilles dans la poche, même si le dispositif de retenue de feuilles est en position renversée ou disposé latéralement.
