A display page assembly for holding substantially planar articles includes a base layer, an anchoring layer, and a protective layer. The anchoring layer is attached to the base layer and includes a plurality of mounting apertures formed therein. The plurality of mounting apertures are arranged for receiving a portion of a substantially planar article therein to secure the substantially planar articles relative to the page. The protective layer is attached relative to the anchoring layer to cover the substantially planar article.

A centrally tabbed adhesive tape strip pad and centrally tabbed adhesive tape flag pad in which the centrally positioned pull tab portion of the leader strip facilitates initiation of dispensing without the use of prethreaded leader bands and facilitates insertion of a new pad into typical refillable dispensers.

Method of making adhesive tape strip and tape flag pads with center tabbed leader strip

The present invention provides pressure-sensitive adhesive beads that comprise a tacky pressure-sensitive adhesive core and a non-tacky shell material that surrounds the area wherein the beads are capable of being positioned via magnetic means. The present invention also provides method(s) of preparing adhesive coated substrates using pressure-sensitive adhesive bead(s) that are magnetically responsive, electrostatically responsive, or both by using magnetic forces, electrostatic forces or both.

Adhesive tape strip and tape flag pads with center tabbed leader strip

A dispenser package including a stack of flexible sheets adhered together by layers of pressure sensitive adhesive with first and second ends of successive sheets in the stack adjacent; and an enclosure in which the stack of sheets is positioned having top wall portions with spaced opposed surfaces that define a wide slot. The first end portion of the uppermost sheet on the stack projects through the slot and rests against the adjacent first abutment surface. As that uppermost sheet is pulled through the slot, successive portions of it will peel away from the first underlying sheet in the stack until it contacts the second abutment surface, whereupon the first end portion of the first underlying sheet separates from the second underlying sheet, the first end portion of the first underlying sheet folds and moves through the slot with the second end portion of the uppermost sheet to leave, after the uppermost sheet is fully peeled from the first portion of the first underlying sheet, the first end portion of the first underlying sheet in a position projecting through the slot and resting against the second abutment surface in a position where it too may be grasped for manual removal in a similar manner.

Adhesive sheet pad with center tabbed leader strip

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. The strips have un-adhered portions or their adhesion to adjacent strips is controlled so that when the stack of strips is positioned in the chamber with the first end portion of the uppermost strip in the stack projecting through the slot and resting against the adjacent abutment surface, and tension is applied to that uppermost strip to pull it through the slot, that tension will cause successive portions of the uppermost strip to peel from the first underlying strip in the stack and will cause separation of the first end portion of the first underlying strip from the second underlying strip, and movement of the first end portion of the first underlying strip through the slot with the second end portion of said uppermost strip to leave, after the uppermost strip is fully peeled from the first portion of the first underlying strip, the first end portion of that first underlying strip in a position projecting through the slot and resting against one of the abutment surfaces disposed in a position where it may be grasped for manual removal in a manner similar to the removal of the uppermost strip.

Attachment strips

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.

Header padded stationery having an adhesive tape strip pad, adhesive tape flag pad and/or adhesive note pad recessively mounted to the header of the stationery pad.

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. The strips have un-adhered portions or their adhesion to adjacent strips is controlled so that when the stack of strips is positioned in the chamber with the first end portion of the uppermost strip in the stack projecting through the slot and resting against the adjacent abutment surface, and tension is applied to that uppermost strip to pull it through the slot, that tension will cause successive portions of the uppermost strip to peel from the first underlying strip in the stack and will cause separation of the first end portion of the first underlying strip from the second underlying strip, and movement of the first end portion of the first underlying strip through the slot with the second end portion of said uppermost strip to leave, after the uppermost strip is fully peeled from the first portion of the first underlying strip, the first end portion of that first underlying strip in a position projecting through the slot and resting against one of the abutment surfaces disposed in a position where it may be gasped for manual removal in a manner similar to the removal of the uppermost strip.

Adhesive beads comprise a core comprising a pressure sensitive adhesive material and an essentially discontinuous organic polymer disposed about the core. The beads are free-flowing at room temperature. Upon application of heat and/or pressure the core is activated and blends with the coating to provide a pressure sensitive adhesive.

Adhesive beads

The present invention provides pressure-sensitive adhesive beads that comprise a tacky pressure-sensitive adhesive core and a non-tacky shell material that surrounds the area wherein the beads are capable of being positioned via magnetic means. The present invention also provides method(s) of preparing adhesive coated substrates using pressure-sensitive adhesive bead(s) that are magnetically responsive, electrostatically responsive or both by using magnetic forces, electrostatic forces or both.

A frame assembly for use on a device such a computer monitor having a front viewed surface surrounded by a housing. The frame assembly includes a stiff frame having generally planar front and rear surfaces that includes elongate border portions having inner edge surfaces that define an opening through the frame corresponding in shape to the front viewed surface. The rear surface of the frame can be attached along the front surface of the housing with the opening in the frame aligned with the front viewed surface, and a layer of repositionable pressure sensitive adhesive adhered to the frame is accessible along the front surface of the frame so that sheets of paper and other objects can be releasably adhered thereto. The frame assembly can be supplied as a part of a composite that can provide other separable smaller bulletin boards or frames that also can have pressure sensitive adhesive accessible along their front surfaces.
