  • Patent number: 4951821
    Abstract: The packing corner of the present invention includes a resilient exterior frame member formed from first and second generally J-shaped leg members, each leg member having a back portion, a bottom portion and a leg portion. The back portions of the J-shaped leg members are connected at their free ends such that the leg portions are adjacent and spaced apart and oriented to abut the edges of a corner of a photograph. A flange projects from the lower edge of each leg portion for supporting the corner of a photograph thereon. The packing corner has an interior support frame connected to the exterior frame so as to assist in resiliently returning the exterior frame to its original shape after any deformation thereof. The bottom of the packing corner has a pair of walls depending from the back portions of the J-shaped leg members, with a plate secured therebetween in a plane generally parallel to the flanges.
