• the present invention relates to hanger sheets, typically of card stock and printed with trademark and product information, that are engaged with manually operated tape dispenser and tape roll assemblies and are adapted to be hung from pegs in a sales display area.
• Such a hanger sheet typically is removed from the tape dispenser and tape roll assembly before it is used to dispense tape.
• That hanger sheet has a first end portion attached to the frame ofthe dispenser by sonic welding, and a second end portion projecting from the blade support portion ofthe dispenser that has an opening adapted to receive a peg in a sales display area to hang the tape dispenser from the peg.
• That hanger sheet is perforated between the portions, and its second end portion is typically removed along the line of perforations and discarded by a purchaser prior to dispensing tape from the dispenser.
• U.S. Patent No. 5,468,332 issued November 21, 1995 describes an improved tape dispenser generally ofthe type described above and also describes a novel means by which a card stock card or hanger sheet ofthe type described above could be attached to it.
• That hanger sheet attachment means includes engagement of portions ofthe card under an opposed pair of spaced and aligned plate-like attachment portions formed on the frame ofthe dispenser. Disclosure ofthe Invention
• the present invention provides an improved means for attaching a card or hanger sheet to a dispenser such as (but not limited to) the dispenser described in U.S. Patent No. 5,468,332 issued November 21, 1995, and illustrated in design Patent No. D-362,684 issued September 26, 1995.
• a tape dispenser including a molded polymeric frame with a blade support portion on which is mounted a cutting blade, and a hanger sheet (e.g., of card stock and printed with trademark and use information) having a first end portion engaged with the frame ofthe dispenser, and a second portion projecting from the dispenser and having an opening adapted to receive a peg in a sales display area so that the tape dispenser can be hung from the peg by the hanger sheet.
• the blade support portion ofthe dispenser comprises a plurality of spaced projections from an inner surface of a dispenser wall, which projections have generally coplanar distal end surfaces.
• the first end portion ofthe hanger sheet has openings receiving the projections with the first end portion ofthe sheet around the projections, and the blade is mounted along the distal end surfaces ofthe projections with the first end portion ofthe hanger sheet between the cutting blade and the inner surface of the wall supporting the projections.
• the projections ofthe cutter support portion are elongate and are spaced along an end ofthe frame with the lengths ofthe projections at a right angle to that end, the cutting edge on the blade is parallel with and disposed at that end, and the second end portion of the hanger sheet projects past the cutting edge and that end ofthe frame.
• the first end portion of the hanger sheet can have one or more paths of weakness (e.g., lines of perforations or thinned portions ofthe hanger sheet) along which parts ofthe hanger sheet may be separated or torn to facilitate removing the hanger sheet from the frame.
• paths of weakness e.g., lines of perforations or thinned portions ofthe hanger sheet
• such a path of weakness can extend transverse of the hanger sheet through the openings in the first portion ofthe hanger sheet so that the hanger sheet can easily be torn into two parts and those parts can be removed from the dispenser; or the first end portion of the hanger sheet can have generally parallel paths of weakness from its projection receiving openings to an adjacent edge ofthe hanger sheet along which parallel paths of weakness the hanger sheet may be torn so that the first portion ofthe hanger sheet can be pulled from around the projections and the entire hanger sheet can be separated from the tape dispenser.
• Figure 1 is a perspective view of a combination of a tape dispenser, a roll of tape, and a hanger sheet according to the present invention
• Figure 2 is a bottom view ofthe combination shown in Figure 1 ;
• Figure 3 is a bottom view ofthe combination shown in Figure 1 with a cutting blade ofthe tape dispenser removed to show detail ofthe hanger sheet;
• Figure 4 is a cross sectional view ofthe combination of Figure 1 taken approximately along line 4-4 of Figure 1 ;
• Figure 5 is a bottom view similar to Figure 3 which illustrates a modification in the hanger sheet ofthe combination.
• FIG. 9 there is shown a combination 9 according to the present invention of a tape dispenser 10 for a roll 1 1 of tape including a supply length ofthe tape wound on a core 13; and a hanger sheet 8 for the dispenser 10.
• the tape on the roll 1 1 can, for example, be one ofthe 2 inch wide tapes including a coating of aggressive pressure sensitive adhesive on a clear or tan colored polypropylene backing or on a polymeric backing that includes longitudinally extending fiberglass filaments that are sold as packaging or mailing tape by Minnesota Mining and Manufacturing Company, St. Paul, Minnesota.
• the dispenser 10 comprises a frame 14 integrally molded of a polymeric material (e.g., polystyrene), and a thin metal plate or blade 18 attached to the frame 14.
• the metal plate or blade 18 provides means for defining a generally straight tape cutting edge 16 comprising a row of generally triangular teeth that are adapted to transversely cut the tape without being excessively sharp so that they do not cause an undue risk of cutting a person using the dispenser 10.
• the frame 14 ofthe dispenser 10 comprises a projecting cutter support portion 20.
• the cutter support portion 20 includes a wall having slightly curved but generally planar parallel outer and inner surfaces 15 and 17, and a plurality of spaced elongate ribs or projections 22 projecting from the inner surface 17 ofthe wall and disposed at right angles to an end 19 ofthe frame 14.
• the projections 22 have generally coplanar distal end surfaces 21 on which the blade 18 is mounted by blade attachment means with its cutting edge 16 at the end 19 ofthe frame 14. That blade attachment means is provided by posts 23 projecting from the distal end surfaces 21 and extending though close fitting openings in the blade 18, which posts 23 have cold formed heads 25 engaging the surface ofthe blade 18 opposite the projections 22.
• the hanger sheet 8 includes a first end portion 50 adjacent a first end 51 of the hanger sheet 8 that has openings receiving the projections 22 with the first end portion 50 ofthe sheet 8 around the projections 22.
• the hanger sheet 8 also includes a second portion 52 adjacent a second end 53 ofthe sheet 8 that has a generally triangular opening 54 adapted to receive a peg in a sales display area to hang the hanger sheet 8 and tape dispenser 10 combination from that peg,
• the blade attachment means mounts the blade 18 along the distal end surfaces 21 ofthe projections 22 with the first end portion 50 ofthe hanger sheet 8 between the cutting blade 18 and the inner surface 17, and with the second end portion 52 ofthe hanger sheet 8 projecting past the cutting edge 16 ofthe blade 18 and the end 19 ofthe frame 14.
• the projections 22 are sized to space the blade 18 from the inner surface 17 at the end 19 ofthe frame 14 by a larger distance (e.g., 0.020 inch) than the thickness ofthe hanger sheet 8 (e.g., 0.015 inch) so that the hanger sheet 8 is not clamped in that space.
• the first end portion 50 ofthe hanger sheet 8 has a path of weakness or line of perforations 56 defining parts ofthe hanger sheet 8 that may be separated or torn to facilitate removing the hanger sheet 8 from the frame 14. As illustrated (see Figure 3), that line of perforations 56 extends transverse ofthe hanger sheet 8 through the openings in the first end portion 50 ofthe hanger sheet 8 through which the projections 22 project.
• a user simply pulls on its second end portion 52 until it separates or tears into two parts along the line of perforations 56, after which those parts into which the hanger sheet 8 has been separated will be unattached to the dispenser and can be disposed of.
• FIG. 5 An alternative to the line of perforations 56 illustrated in Figures 1-4 is shown in Figure 5.
• the first end portion 50' ofthe hanger sheet 8' can have generally parallel paths of weakness or lines of perforations 58 from the openings in the first end portion 50' ofthe hanger sheet 8' through which the projections 22 project to the adjacent first end 51 ' ofthe hanger sheet 8'.
• Such lines of perforations 58 define parts ofthe hanger sheet 8' that may be separated by tearing the hanger sheet 8' along the perforations 58 to facilitate separation ofthe hanger sheet 8' from the frame 14 ofthe dispenser 10.
• the hanger sheet 8' When the second end portion 52' ofthe hanger sheet 8' is pulled on to separate it from the dispenser 10, the hanger sheet 8' will tear or separate along the lines of perforations 58 and can be pulled from the dispenser 10.
• the use of such lines of perforations 58 provides the advantage that the hanger sheet 8' will remain in one piece after it is separated from the dispenser 10, thereby facilitating its disposal.
• the hanger sheet can also be made without any perforations, and will typically tear apart between the openings receiving the projections 22 when the second end portion ofthe hanger sheet is pulled on to separate it from the dispenser 10.
• the hanger sheet 8 is of made of card stock (e.g., 0.014 inch thick solid bleached sulfate) and bears printed indicia on both sides providing trademark and use information.
• the frame 14 ofthe dispenser 10 also includes opposite, generally parallel side wall portions 26 that are attached along opposite edges ofthe cutter support portion 20 and are disposed at about right angles with respect to the cutting edge 16 and with respect to the support portion 20.
• C-shaped parts 27 ofthe side wall portions 26 ofthe frame support opposed generally C-shaped hub portions
• the hub portions 28 are arcuate about an axis 29 parallel to the tape cutting edge 16, provide peripheral surfaces adapted to rotatably support the cylindrical inner surface ofthe core 13 for rotation about the axis 29, and are adapted to project into the opposite ends of an opening in the core 13 on the side of the core 13 opposite the blade 18 to rotatably support the roll of tape 1 1.
• the side wall portions 26 are resiliently flexible between the hub portions 28 and the cutter support portion 20 so that they can be resiliently bent apart to afford positioning the roll 1 1 of tape between the hub portions 28 and removing the empty core 13 from therebetween.
• the frame 14 also includes opposed locating tab portions 30 projecting toward each other from the adjacent surfaces ofthe side wall portions 26 at a distance from the axis 29 ofthe hub portions 28 (e.g., 1.38 inches) that is significantly less than or about half plus or minus 10 percent the distance between the cutting edge 16 and the axis 29 ofthe hub portions 28 (e.g., 2.76 inches).
• the locating tab portions 30 have retaining surfaces 32 adjacent the cutter support portion 20 that are arcuate or cylindrically convex about an axis parallel to the axis
• the locating tab portions 30 also have cam surfaces 33 extending from adjacent the side wall portions 26 to the adjacent or inner ends ofthe locating tab portions 30 on the sides ofthe locating tab portions 30 opposite the retaining surfaces 32.
• the cam surfaces 33 cause tape being pulled from the roll 1 1 of tape on the side ofthe tab portions 30 opposite the retaining surfaces 32 to be guided between and around the locating tab portions 30 when relative movement is caused between the dispenser 10 and the tape being withdrawn to transversely cut the tape with the cutting edge 16 ofthe blade 18.
• the parts ofthe cam surfaces 33 along the lengths ofthe cam surfaces 33 are disposed at angles of greater than about 45 degrees, and preferably greater than about 50 degrees, with respect to the surfaces adjacent the cutter support portion 20 of imaginary planes passing through the axis 29 ofthe hub portions 28 and those parts; the measurements of those angles being taken in planes normal to the surfaces ofthe imaginary planes.
• the cam surfaces 33 can be straight or arcuate, include straight and arcuate parts, or include different parts that are arcuate about different axes or are straight and disposed at different angles with respect to the imaginary planes. Also, the opposite ends ofthe cam surfaces 33 can be disposed at the same or different distances from the axis 29 of the hub portions 28.
• the locating tab portions 30 project a small distance into the path ofthe tape (e.g., 0.33 inch into the path on each side ofthe path for 2 inch wide tape that the dispenser 10 is adapted to dispense) thereby requiring only a small percentage of the width ofthe tape (e.g., about 27 percent) to be moved around the locating tab portions 30 by the cam surfaces 33.
• the space between the adjacent spaced ends ofthe locating tab portions 30 is at least 60 percent (e.g., 73 percent) ofthe width ofthe 2 inch tape the dispenser is intended to dispense.
• An arched portion 34 ofthe frame 14 is joined to and projects from the edge ofthe cutter support portion 20 opposite the cutting edge 16, and extends partially around the roll of tape 1 1.
• the arched portion 34 is resiliently flexible and has a generally cylindrically concave surface adjacent the periphery ofthe roll 1 1 of tape in the dispenser 10.
• the arched portion 34 is adapted to be received in the palm of a user's hand to normally space the user's hand from the rotating roll 11 of tape as tape is being dispensed from the tape dispenser 10, and can be pressed into engagement with the periphery ofthe roll 1 1 of tape to stop tape from being withdrawn from the dispenser when the user wishes to sever the tape with the cutting edge 16.
• the arched portion 34 also discourages a user ofthe tape dispenser from trying to cut the tape using the wrong side ofthe tape cutting edge 16.
• the frame 14 ofthe dispenser 10 adjacent the cutter support portion 20 has a generally triangular opening 40 similar in shape and orientation to the opening 54 in the hanger sheet 8.
• the opening 40 allows the dispenser 10 to be hung from a peg either before or after the hanger sheet 8 is removed, as may be desirable for storage ofthe dispenser 10 after the hanger sheet 8 is removed, or to stagger the vertical locations of dispensers on a peg by alternately hanging them from the opening 54 in the hanger sheet and the opening 40 to thereby place a larger number of dispensers 10 on that peg than if they were all hung using the hanger sheet 8.
• a user can use the dispenser 10 by pulling an end ofthe length of tape away from the tape on the roll 11, applying the end ofthe tape to the item to be taped, and pulling the dispenser 10 away from the item to dispense the desired length of tape. Ifthe end ofthe length of tape is initially adhered to the retaining surfaces 32, the tape will be pealed away from those retaining surfaces 32 and will be pulled from the roll 1 1 in the space between the retaining surfaces 32 and the cutting edge 16 ofthe blade 18.
• the user pulls that end from the surface ofthe roll 1 1 which may most easily be done between the side wall portions 26 on the side ofthe locating tab portions 30 opposite the cutting edge 16 and the distal end ofthe arcuate portion 24.
• the user may continue to pull tape from the roll 1 1 in that area, however, when a sufficient length ofthe tape has been withdrawn, the user will orient the dispenser 10 to press the cutting edge 16 ofthe blade 18 against the tape so that the edge 18 transversely severs the tape.
• Tension in the tape during such orientation ofthe dispenser 10 will cause the cam surfaces 33 to guide the opposite edges ofthe tape between and around the locating tab portions 30 and will position the tape in the space between the retaining surfaces 32 and the cutting edge 16 before the cutting edge 16 can sever the tape.
• the newly formed end portion ofthe tape will contact and releasably adhere to the retaining surfaces 32, which is facilitated because ofthe convex curvature ofthe retaining surfaces 32 and complimentary concave curvature ofthe newly formed end portion ofthe tape that is caused by stresses formed in the backing ofthe tape when it was wound on the roll 1 1.
• the adhesion ofthe newly formed end portion ofthe tape to the retaining surfaces 32 will thus normally be retained until the end portion ofthe tape is pealed away by a user when another length ofthe tape is desired.
