Patent number: 5798159Abstract: 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.Type: GrantFiled: May 17, 1996Date of Patent: August 25, 1998Assignee: Minnesota Mining and Manufacturing CompanyInventors: Joseph P. Callahan, Jr., Bruce E. Samuelson

Patent number: 5786062Abstract: Attachment strips that can be withdrawn from an enclosure, each comprising a flexible backing layer, a field of hooks along and projecting from one of its surfaces; and a first layer of pressure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: GrantFiled: May 27, 1997Date of Patent: July 28, 1998Assignee: Minnesota Mining and Manufacturing CompanyInventors: Joseph P. Callahan, Jr., Kevin M. Hamer, Patricia R. Konsti, David C. Windorski

Patent number: 5755356Abstract: 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.Type: GrantFiled: April 15, 1996Date of Patent: May 26, 1998Assignee: Minnesota Mining and Manufacturing CompanyInventors: Willem V. Bastiaens, Joseph P. Callahan, Jr., David C. Windorski, Timothy A. Jacobs

Patent number: 5625006Abstract: 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.Type: GrantFiled: January 24, 1996Date of Patent: April 29, 1997Assignee: Minnesota Mining and Manufacturing CompanyInventors: Joseph P. Callahan, Jr., Rudyard M. Enanoza, Mark D. Weigel

Patent number: 5549267Abstract: 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.Type: GrantFiled: January 10, 1994Date of Patent: August 27, 1996Assignee: Minnesota Mining and Manufacturing CompanyInventors: June M. Armbruster, Willem V. Bastiaens, Joseph P. Callahan, Jr., Steve W. Moris, David W. Stegink
