Definitions

  • the present invention relates to stacks of sheets and dispenser packages for stacks of sheets.
  • Sheets from Post-it brand note pads available from Minnesota Mining and Manufacturing Company are used extensively as such sheets, and are particularly useful for that purpose because a repositionable pressure sensitive adhesive with which they are coated allows them to be placed on and removed from a document without damage to the document.
  • DE,U,8616465 describes a plurality of sheets each comprising a layer of flexible polymeric material having a coating of pressure sensitive adhesive on at least a second end portion of a bottom side surface adjacent a second end, which sheets are releasably adhered to each other by adhesion of the coatings of pressure sensitive adhesive to portions of top surfaces of underlying sheets to form a stack with adjacent ends of the sheets aligned and with the first and second ends of successive sheets in the stack being adjacent, and which sheets have means for preventing adhesion of first end portions of the sheets adjacent their first ends to underlying sheets in the stack.
  • DE,U,8616465 also describes a dispenser package comprising a plurality of flexible sheets, each of which sheets comprises a layer of material having a coating of pressure sensitive adhesive on at least a second end portion of a bottom side surface adjacent a second end, which sheets are releasable adhered to each other by adhesion of the coatings of adhesive to portions of top surfaces of underlying sheets adjacent first ends of the underlying sheets to form a stack with adjacent ends of the sheets aligned and with the first and second ends of successive sheets in the stack adjacent, and which sheets have means for preventing adhesion of minor first end portions of the sheets adjacent their first ends to underlying sheets in the stack; and an enclosure comprising walls defining a chamber in which the stack of sheets is positioned, which walls include a top wall including a portion defining a transverse slot parallel to the ends of the sheets, and positioned adjacent an uppermost sheet in the stack with the first end portion of the uppermost sheet projecting through the slot.
  • the slot is fixed in location relative to the stock and cannot
  • This problem is also overcome in the dispenser package according to the present invention by providing means for affording relative movement between the portion of the top wall defining the slot and the uppermost sheet in the stack (i.e., by making the stack movable back and forth in the chamber as is claimed in Claim 5 or making at least a portion of the uppermost wall of the enclosure movable relative to the rest of the housing and the stack as is claimed in Claim 10) from initial to final relative positions to afford, as the uppermost sheet is pulled through the slot, alignment of the slot with successive portions of the uppermost sheet toward the second end of the uppermost sheet as the successive portions are peeled from an underlying sheet in the stack.
  • the slot is positioned transverse of the second end portion of the uppermost sheet and the first end portion of the underlying sheet to afford folding and movement through the slot of the underlying sheet with the second end portion of the uppermost sheet to leave, after the uppermost sheet is fully peeled from the underlying sheet, the first end portion of the underlying sheet in a position projecting through the slot and the underlying sheet and portion of the top wall defining the slot in their initial relative position.
  • the dispenser package can be used to dispense sheets having any of the structural features recited in the claims dependent on Claim 5 and 10, including sheets having non adhesive coated first end portions as described above to provide means for preventing adhesion of first end portions of the sheets adjacent their first ends to underlying sheets in the stack.
  • means can be provided by coatings of release materials on parts of the top surfaces of the sheets adjacent their second ends, and such sheets can be coated with pressure sensitive adhesive over their entire bottom surfaces, which may be useful for sheets used for certain purposes that may or may not have visually distinctive portions.
  • the sheet 10 comprises only a single elongate rectangular layer 11 of transparent flexible polymeric material (e.g. preferably 0.0056 centimeter or 0.0022 inch thick cellulose acetate although such material from 0.0038 to 0.0076 centimeter thick is also usable) having opposite major side surfaces and first and second opposite ends 14 and 15, and having a coating 16 of repositionable pressure sensitive adhesive (e.g., the pressure sensitive adhesive described in U.S.
  • Patent No.s 3,691,140 and 4,166,152 on a second end portion 18 of one of the side surfaces adjacent the second end 15 while being free of adhesive on both of the side surfaces along a first tab end portion 19 thereof adjacent the first end 14.
  • the tab end portion 19 is smaller in area than the second end portion 18 (e.g., about one half its area as illustrated), and is printed with a bright colored ink (e.g., red, green or yellow) to make it visually distinctive; while the adhesive coated second end portion 18 is generally transparent when adhered to a substrate so that it will not obscure a substrate to which it is attached.
  • the side surface opposite the coating 16 of adhesive is adapted to be written on by methods known in the art.
  • the sheet 20 comprises an elongate rectangular layer 21 of transparent flexible polymeric material (e.g., 0.0056 centimeter thick cellulose acetate) having opposite major side surfaces and first and second opposite ends 24 and 25, and having a coating 26 of repositionable pressure sensitive adhesive on one of the side surfaces.
  • transparent flexible polymeric material e.g., 0.0056 centimeter thick cellulose acetate
  • the coating 26 of adhesive is exposed on a second end portion 28 of the side surface adjacent the second end 25, however the sheet 20 is free of adhesive on both of the side surfaces along a first tab end portion 29 thereof adjacent the first end 24 (which tab end portion 29 is smaller in area than the second end portion 28) because of a second layer 30 of polymeric material (e.g., 0.0038 centimeter thick cellulose acetate) adhered to the adhesive coated first layer 21 along the tab end portion 29.
  • the second layer 30 is printed or died to make it brightly colored (e.g., red, green or yellow) so that the tab end portion 29 is visually distinctive, while the adhesive coated second end portion 28 is generally transparent when adhered to a substrate so that it will not obscure a substrate to which it is attached.
  • a plurality of the flexible sheets 10 are preferably included in a dispenser package 32 according to the present invention in which the sheets 10 are releasably adhered to each other by the coatings 16 of pressure sensitive adhesive and with the bottom sheet 10 adhered to a bottom sheet 33 to form a stack 34 with adjacent ends 14 and 15 of the sheets 10 aligned and with the first and second ends 14 and 15 of successive sheets in the stack 34 adjacent.
  • the dispenser package 32 also includes a molded plastic enclosure 36 comprising walls defining a chamber 38 in which the stack 34 of sheets 10 is positioned, which walls include upstanding side walls 35, a bottom wall 37 that could be removable from the side walls 35 to afford replacing the stack 34, and a top wall 40.
  • the top wall 40 includes a portion defining a generally central transverse slot 42 parallel to the ends 14 and 15 of the sheets 10 positioned adjacent an uppermost sheet 10 in the stack (which uppermost sheet is identified as 10a in Figures 4 through 6) with the first end portion 19 of the uppermost sheet 10a projecting through the slot 42.
  • Means are provided for affording relative movement between the portion of the top wall 40 defining the slot 42 and the uppermost sheet 10a from initial ( Figure 4) to final ( Figure 5) relative positions by making the chamber 38 longer than the stack 34 so that the stack 34 can shuttle back and forth in the chamber 38 to afford, as the uppermost sheet 10 is manually pulled through the slot 42, alignment of the slot 42 with successive portions of the uppermost sheet 10a toward the second end 15 of the uppermost sheet 10a as the successive portions are peeled from an underlying sheet 10 in the stack 34 (identified as 10b in Figures 4 through 7) to which the uppermost sheet 10a is adhered.
  • the slot 42 is along the second end portion 18 of the uppermost sheet 10a and the first end portion 19 of the underlying sheet 10b.
  • the first end portion 19 of the underlying sheet 10b is not coated with adhesive to provide means for preventing adhesion of that first end portion 19 to the sheet 10 below the underlying sheet 10b (which sheet below the underlying sheet 10b is identified as 10c in Figures 4 through 7) and thereby afford transverse folding of the underlying sheet 10b ( Figure 6) at about the juncture between the tab and second portions 19 and 18 thereof and movement of the first end portion 19 of the underlying sheet 10b through the slot 42 ( Figure 6) with the second end portion 18 of the uppermost sheet 10a to leave, after the uppermost sheet 10a is fully peeled from the underlying sheet 10b, the first end portion 19 of the underlying sheet 10b in a position projecting through the slot 42 in the top wall 40 ( Figure 7) and the underlying sheet 10b and the portion of the top wall 40 defining the slot 42 in the initial relative position with
  • the portion of the top wall 40 defining the slot 42 preferably comprises opposed parallel cylindrically convex guide surface portions 44 adjacent the stack 34 leading to opposed parallel planar guide surface portions 46 extending at a right angle to the major portion of the surface of the top wall 40 adjacent the stack 34.
  • the guide surface portions 44 and 46 insure that the second end portions 18 of sheets 10 being pulled from the stack 34 will be peeled away (and thus curl induced in the sheets 10 will be restricted), even if the first end portions 19 of those sheets 20 are pulled in a direction generally parallel to the top wall 40 rather than at a right angle thereto, and the spacing between the surface portions 44 and 46 helps prevent a phenomenon in which more than one sheet 10 is pulled through the slot 42 by the sheet 10a being removed which will happen if contact occurs between folded tab and adhesive coated second end portions 19 and 18 of the underlying sheet 10b as the underlying sheet 10b is pulled from the dispenser package 32 by the uppermost sheet 10a, and which phenomenon is exacerbated when that uppermost sheet 10a is pulled in a direction generally parallel to the top wall 40 rather than at a right angle thereto.
  • Planar guide surface portions 46 at least about 0.5 centimeter (0.2 inch) long in a direction normal to the top surface of the stack 34 and spaced about 0.15 to 0.2 centimeter (0.06 to 0.075 inch) apart and arcuate guide surface portions 44 with a 0.15 centimeter (0.06 inch) radius have been found to greatly restrict that phenomenon when sheets 10 of the materials described above are dispensed, and also present the end portion 19 of the sheet 10 projecting through the slot 42 at close to a right angle to the top wall 40. Also, the phenomenon described above has been found to be further minimized by applying a release agent such as silicone to the tab portion 19, for example, by including it in the ink printed thereon.
  • a release agent such as silicone
  • FIG 8 illustrates a second embodiment of a dispenser package 62 according to the present invention in which a plurality of the sheets 10 are releasably adhered to each other by the coatings 16 of pressure sensitive adhesive and to a bottom sheet 65 to form a stack 64 identical to the stack 34.
  • the dispenser package 62 also includes an enclosure 66 comprising walls defining a chamber 68 about the same size as the stack 64 in which the stack 64 of sheets 10 is positioned.
  • the walls defining the enclosure 66 include a bottom wall 67, upstanding side walls 69, and a top wall 70.
  • the top wall 70 in the dispenser package 62 is partially defined by a pair of cylindrical members 71 extending transversely across the top edges of the side walls 69.
  • the members 71 are spaced apart to define a generally central transverse slot 72 between the members 71, which slot 72 is parallel to the ends 14 and 15 of the sheets 10 and is positioned adjacent an uppermost sheet 10a in the stack 64 with the first end portion 19 of the uppermost sheet 10a projecting through the slot 72.
  • the ends of the cylindrical members are mounted on parallel plates 74 slidably mounted on the side walls 69 for reciprocal movement between limits defined by fixed portions 76 of the top wall 70 to provide means for affording relative movement between the portion of the top wall 70 defining the slot 72 and the uppermost sheet 10a from initial to final relative positions so that the portion of the top wall 70 defining the slot 72 can shuttle back and forth over the chamber 68 to afford, as the uppermost sheet 10a is manually pulled through the slot 72, alignment of the slot 72 with successive portions of the uppermost sheet 10a toward the second end 15 of the uppermost sheet 10a as the successive portions are peeled from an underlying sheet 10b in the stack 64.
  • the slot 72 is along the second end portion 18 of the uppermost sheet 10a and the first end portion 19 of the underlying sheet 10b to afford folding and movement through the slot 72 of the first end portion 19 of the underlying sheet 10b with the second end portion 18 of the uppermost sheet 10a to leave the first end portion 19 of the underlying sheet 10b in a position projecting through the slot 72 in the top wall 70 and the underlying sheet 10b and portion of the top wall 70 defining the slot 72 in the initial relative position after the uppermost sheet 10a is fully peeled from the underlying sheet 10b.
  • removal of the uppermost sheet 10a and positioning of the first end portion 19 of the underlying sheet 10b through the slot 72 in the dispenser package 62 occurs in essentially the same manner as removal of a sheet 10 from the dispenser package 32 except for movement of the portion of the top wall 70 defining the slot relative to the side and bottom walls 69 and 67 in the dispenser package 62 rather that movement of the stack 34 in the chamber 38 in the dispenser package 32.
  • FIG. 9 of the drawing there is shown a third embodiment of a sheet 80 that can be used to form a stack 94 included in a dispenser package 92 according to the present invention illustrated in Figure 10.
  • the sheet 80 comprises a rectangular layer 81 of transparent flexible polymeric material having top and bottom major side surfaces and first and second opposite ends 84 and 85, having a coating 86 of pressure sensitive adhesive (which adhesive might be repositionable or more aggressive) on the bottom side surface, and having a coating of release material (e.g., silicone) on a part 88 of the top surface of the sheet 80 adjacent its second end 85.
  • pressure sensitive adhesive which adhesive might be repositionable or more aggressive
  • release material e.g., silicone
  • a plurality of the flexible sheets 80 are releasably adhered to each other and to a bottom sheet 90 by the coatings 86 of pressure sensitive adhesive to form the stack 94 with adjacent ends 84 and 85 of the sheets 80 aligned and with the first and second ends 84 and 85 of successive sheets in the stack 94 adjacent.
  • the dispenser package 92 also includes an enclosure 96 (essentially identical to the enclosure 36) comprising walls defining a chamber 98 in which the stack 94 of sheets 80 is positioned, which walls include upstanding side walls 99, a bottom wall 97, and a top wall 100.
  • the top wall 100 defines a generally central transverse slot 102 parallel to the ends 84 and 85 of the sheets 80 positioned adjacent an uppermost sheet 80 in the stack (identified as 80a) with a first end portion 89 of the uppermost sheet 80a projecting through the slot 102.
  • Means are provided for affording relative movement between the top wall 100 and the uppermost sheet 80a from an initial relative position illustrated in Figure 10 to a final relative position (which is not shown, but is essentially the same as the final relative position of the stack 34 and top wall 40 in the dispenser package 32 illustrated in Figure 5) by making the chamber 98 longer than the stack 94 so that the stack 94 can shuttle back and forth in the chamber 98 to afford, as the uppermost sheet 80 is manually pulled through the slot 102, alignment of the slot 102 with successive portions of the uppermost sheet 80a toward the second end 85 of the uppermost sheet 10a as the successive portions are peeled from an underlying sheet 80 in the stack 94 (identified as 80b) to which the uppermost sheet 80a is adhered.
  • the slot 102 is along a second end portion 87 of the uppermost sheet 80a and the first end portion 89 of the underlying sheet 80b, which first end portion 89 of the underlying sheet 80b is adjacent the coating of release agent on the part 88 of the sheet 80 beneath it (identified as 80c), which part 88 coated with release agent provides means for preventing adhesion of that first end portion 89 to the part 88 of the sheet 80c below the underlying sheet 80b and thereby affords transverse folding of the underlying sheet 80b and movement of the first end portion 89 of the underlying sheet 80b through the slot 102 with the second end portion 88 of the uppermost sheet 80a to leave, after the uppermost sheet 80a is fully peeled from the underlying sheet 80b, the first end portion 89 of the underlying sheet 80b in a position projecting through the slot 102 in the top wall 100 and the underlying sheet 80b and the top wall 100 in the initial relative position with respect to each other.
