  • Patent number: 9061540
    Abstract: A paperclip tab for coupling to an object. The paperclip tab can include a paperclip having a first leg and a second leg, and a sheet having a front surface and a rear surface opposite the front surface. The sheet can include a first portion, and a second portion overlapping at least part of the first portion, with the rear surface of the first portion and the rear surface of the second portion facing each another, such that a pocket is formed that can retain the first leg of the paperclip. At least a portion of the rear surface of the first portion can be adhered to at least a portion of the rear surface of the second portion. A recessed adhesive zone can be provided on a back of the paperclip tab positioned to face the object when the paperclip tab is coupled to the object.

  • Patent number: 8882153
    Abstract: Recessed adhesive binding systems. One system can include a plurality of sheets arranged in a stack, each of the plurality of sheets having a front surface, a rear surface, and an exposed edge. At least one of the front surface and the rear surface of each of the plurality sheets can include at least one recessed adhesive positioned adjacent the exposed edge to form an at least partially exposed recessed adhesive, which can be selectively activated. The rear surface of a first sheet in the plurality of sheets can be positioned adjacent the front surface of a second sheet in the plurality of sheets, or vice versa, and the exposed edges of the plurality of sheets can be staggered, such that the exposed edge of the second sheet extends further outwardly from the stack than the exposed edge of the first sheet in the stack.
