Abstract:
1. A device manually used to apply tape along a surface to be protected with an edge of the tape extending along a juncture between the surface to be protected and a surface to be treated disposed at about a right angle with respect to the surface to be protected, tape being applied by said device from a roll of tape comprising a core having an axis, a cylindrical periphery around said axis, and a length of tape comprising a backing having opposite major surfaces extending between opposite elongate edges and a layer of pressure sensitive adhesive along one of said major surfaces, said length of tape being wound around said periphery with said edges aligned to form side surfaces for the roll of tape, said device including: a housing adapted to receive the roll of tape, said housing having a guide surface adapted to be slid along the surface to be protected and comprising at least one housing portion having a tape contact part of an inner surface for the housing portion in a first plane, and having in a second plane a guide part of an outer surface for the housing portion adapted to be slid along the surface to be treated and disposed at about a right angle with respect to said guide surface, said first and second planes on said housing portion being disposed relative to each other in a range between being parallel to each other and being disposed at a small angle with respect to each other with said first and second planes intersecting adjacent the intersection of said second plane and a plane along said guide surface; a pressure application structure having an end portion, said end portion having an arcuate peripheral surface around an axis, and an outer edge; means mounting the pressure application structure on the housing for a limited predetermined amount of pivotal movement away from a position with the axes of the arcuate peripheral surface at a right angle with respect to the first plane on the housing portion, said pivotal movement moving the end portion of the pressure application structure toward a top side of the housing portion opposite the guide surface, said pivotal movement being about a pivot axis spaced from the end portion, transverse to the axis of the peripheral surface, and in a plane at about a right angle with respect to a plane along the guide surface and said peripheral surface, the arcuate peripheral surface on the end portion of the pressure application structure being disposed at an angle of no greater than 90 degrees with respect to the adjacent second plane and projecting from the housing when the pressure application structure is pivoted to said maximum angle to move the end portion of the pressure application structure toward a top side of the housing portion opposite the guide surface; means for journaling the roll of tape on the housing with said tape contact part of the inner surface for the housing portion along one of the side surfaces of the roll of tape; and means for defining a path for the length of tape from the periphery of the roll of tape to the periphery of said pressure application structure at said predetermined location with the adhesive on the tape on the side of the backing opposite the pressure application structure so that the dispenser can be manually positioned with the portion of the housing against the surface to be treated and the guide surface along the surface to be protected, and the dispenser can be moved along the surfaces to be treated and protected to accurately apply and press the tape from the roll of tape on the surface to be protected with the peripheral surface of the pressure application structure and with the edge of the tape at a predetermined relationship with respect to the juncture between the surface to be protected and the surface to be treated.
