  • Patent number: 5786062
    Abstract: Attachment strips that can be withdrawn from an enclosure, each comprising a flexible backing layer, a field of hooks along and projecting from one of its surfaces; and a first layer of pressure sensitive adhesive along one of its surfaces. The strips can be releasably adhered to each other by their layers of adhesive to form a stack in which first and second ends of successive strips are adjacent.
    Type: Grant

  • Patent number: 5755356
    Abstract: A sheet dispenser including a housing, and a stack of dispensable sheets. A front wall of housing has edges that define a slot through which an end portion of the top sheet on the stack projects. That front wall normally projects above the top surface of the stack of sheets to position that end portion of the top sheet in a position projecting above an outer surface of the front wall where it can be easily grasped to withdraw the top sheet from the housing. At least a portion of the front wall is of flexible material so that it can be resiliently bent to lie along the top surface of the stack and thereby reduce the thickness of the dispenser when, for example, it is positioned on one of the pages of a book, magazine, personal organizer or the like that is closed.

  • Patent number: 5526955
    Abstract: Described is a dispenser for sheets received in a cavity in the dispenser that are pulled through an outlet opening in a top wall of the dispenser. The dispenser has access openings that afford inspection of the number of sheets remaining in the dispenser and facilitate engagement of a persons finger with the end portion of one of the sheets that projects through the outlet opening; a cover for the top wall when the dispenser is not in use; and separable portions that allow sheets to be positioned in the cavity. The dispenser can be included in an assembly further including a support member along which the dispenser is releasably attached, which support member can support one or more such dispensers together with dispensers for other items such as tape flags.

  • Patent number: 5524929
    Abstract: A binding assembly including (1) a plurality of support strips; (2) layers of pressure sensitive adhesive (which could be repositionable, removable or permanent pressure sensitive adhesive) along front surfaces of the support strips; and (3) layers of release material on a rear surfaces of the support strips. The support strips are adhered together to form a support strip stack with inner edges of the support strips in alignment, with the layers of pressure sensitive adhesive on the support strips adhered to the layers of release material on adjacent support strips, and with the front surfaces of the support strips uppermost in the support strip stack. The binding assembly further includes binding means along the inner edges of the support strips that affords separation of the support strips and revolving of the support strips relative to each other around axes generally parallel to their inner edges.

  • Patent number: 5411168
    Abstract: 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.

  • Patent number: 5385230
    Abstract: An adjustable tray assembly adaptable for use in desk drawers having side walls spaced at various distances. The tray assembly includes a first portion having a plurality of open top receptacles and a support lip projecting away from one side, and a second portion also with a projecting support lip and mounted on the first portion to affording relative movement between the portions to change the spacing between the first and second support lips so that they can be supported on the upper edge surfaces of the side walls of the drawers of different widths with the first and second portions bridging therebetween. The tray assembly can also include dispensers for office supplies including note paper, tape flags and tape; the tape dispenser being of a novel low profile design.

  • Patent number: 5165570
    Abstract: A dispenser for paper sheets from a stack comprising a plurality of the sheets disposed one on top of another, each sheet having a band of pressure sensitive adhesive coated on one surface adjacent one edge thereof and being free of adhesive coating along a portion adjacent an opposite edge thereof, and the sheets being stacked with the adhesive coating on each successive sheet disposed along alternate opposite sides of the stack and releasably adhering the sheets together to maintain the sheets in the stack. The dispenser has surfaces defining a cavity adapted to receive the stack including opposed end surfaces adapted to be engaged by the opposite sides of the stack, and two spaced friction surface portions extending generally toward each other from the upper ends of the end surfaces which are generally arcuate and concave about an axis parallel to the upper ends of the end surfaces.

  • Patent number: 5158205
    Abstract: The combination of (1) sheets of note paper in a stack with each of the sheets having a narrow band of adhesive coated on its bottom surface along one edge by which the sheet is adhered to the top surface of the adjacent sheet in the stack, the sheets being stacked with the band of adhesive of adjacent sheets at alternate opposite sides of the stack, and (2) a dispenser comprising a housing closely receiving the top, bottom and first side surfaces of the stack of sheets. The housing includes a top wall of flexible material adjacent the top surface of the stack, which top wall has through flanking slits parallel to and flanking side surfaces of the stack and generally centered along those side surfaces, and spaced edge surfaces extending between the flanking slits. The flanking slits and edge surfaces define two opposed flap like portions of the top wall and a slot through the top wall between the flap like portion through which slot projects a portion of the uppermost sheet in the stack.
