  • Patent number: 6427371
    Abstract: The disclosure is directed to several related forms of PICTURE FRAMES for displaying photographs or similar illustrations. More particularly, the disclosure is directed to picture frames constructed from a single flat die-cut foldable paperboard blank convertible into a three-dimensional picture frame without requiring the use of adhesive, adhesive tape, staples, clips or other fastening materials. This is accomplished by the use of rectangular paperboard panels approximately the size of the photo or other picture to be displayed, with infolding flaps on at least three edges of the panel to engage the edges of the photo to entrap the photo and hold it in place.

  • Patent number: 6302363
    Abstract: A refrigerator magnet for holding thin non-magnetic sheet material, such as paper, against a flat, smooth, magnetically attractive metallic surface, such as a refrigerator door. It comprises a one-piece rigid unitary body having a first bottom planar magnetic surface and at least one other adjoining bottom planar magnetic surface. The magnetic surfaces are joined along a common bend line at an obtuse angle. In use one of the magnetic surfaces is in contact with the metallic surface, leaving one or more paper-receiving gaps between the other magnetic surfaces(s) and the metallic surface. The bend line functions as a fulcrum whereby the body may be flipped by application of finger pressure to lift the first magnetic surface from the metallic surface and cause one of the other magnetic surfaces to clamp the paper and hold it magnetically against the metallic surface.
