A sheet dispenser or sheet dispenser subassembly including a coherent stack of tape flags or other adhesive-bearing sheets that can be unobtrusively permanently or removably adhered on a page of a book, catalog, brochure, etc., because it has a supple cover layer that is a thin, tear-resistant polymeric film. The dispenser subassembly has a pressure-sensitive adhesive layer on a peripheral portion of the cover layer by which it can be adhered to the page which then serves as a back layer for the dispenser, whereas the dispenser includes a bottom layer on an outer surface of which is a layer of pressure-sensitive adhesive layer by which the dispenser can be adhered to a surface.

A pop-up sheet dispenser comprising: (a) a stack of sheets disposed one on top of another, each sheet comprising a backing having opposite first and second major side surfaces and opposite first and second ends with ends of the sheets being in alignment in the stack, and a layer of adhesive permanently adhered to the first side surface of said backing, the layers of adhesive of said sheets being releasably adhered along the second surfaces of the adjacent sheets in said stack, at least some of said sheets comprising release means for providing a first adhesion level along first end portions of said sheets adjacent said first ends of said backings between said first side surfaces and the second side surfaces of the adjacent sheets in the stack to which the layers of adhesive are releasably adhered, which first adhesion level provides a sufficiently low or no release force between said first side surfaces and the adjacent sheets to which the adhesive along those first side surfaces are releasable adhered to afford sliding movement between the side surfaces of the adjacent sheets along said first end portions, and attachment means for providing a second adhesion level along second end portions of said sheets adjacent said second ends of said backings between said layers of adhesive and the second side surfaces of the adjacent sheets in the stack to which said layers of adhesive are releasably adhered, which second adhesion level provides a release force that is higher than said sufficiently low release force along said first end portions and firmly adhere the sheets to the adjacent sheets in the stack during sliding movement of the sheets relative to the adjacent sheets along said first end portions while affording peeling away of the sheets from the stack along said second end portions; (b) a supple cover layer less than 0.2 millimeter (0.008 inch) in thickness having inner and outer major surfaces, a central portion, a peripheral portion or portions on at least two opposite sides of said central portion, and a through slot extending transversely across said central portion; (c) said stack of sheets being positioned along the inner surface adjacent said central portion with the first end portion of the uppermost sheet in the stack extending through said slot; (d) a thin, supple bottom layer having inner and outer surfaces, said bottom layer extending over the inner surface of the cover layer and the stack of sheets and being attached to said peripheral portion of the cover layer with the inner surface of the bottom layer adjacent the cover layer to form a chamber around the stack of sheets; (e) said sheets, slot and chamber being adapted to afford dispensing of the sheet having the first end portion extending through the slot when that first end portion is manually pulled through the slot by sequential sliding movement of one of the sheets relative to the adjacent sheet along the first end portion and peeling away of the sheet from the stack along said second end portion, and positioning of the first end portion of an underlying sheet in a position extending through the slot as a result of said dispensing; (f) a layer of pressure-sensitive adhesive on the outer surface of the bottom layer; and (g) a disposable release liner over the surface of the layer of pressure-sensitive adhesive layer opposite the bottom layer, which release liner can be removed to permit the dispenser to be adhered to a surface.
