The present invention relates generally to media of the type including a repositionable adhesive and relates more particularly to a novel medium of the aforementioned type, to a plurality of such media arranged in a stack, the method of manufacturing such media, and the method of using such media.
Media of the type including a repositionable adhesive are commonly used in a variety of venues including, but not limited to, homes, workplaces, and schools, and for a variety of applications, such as note-taking. One common type of medium having a repositionable adhesive is often referred to in the art as a repositionable note paper and includes a small sheet of paper having a top surface and a bottom surface, the top surface is receptive to markings, the bottom surface having a repositionable adhesive applied to a portion thereof, typically as a band of adhesive applied alongside one edge of the sheet.
In use, a handwritten or machine-printed marking is made on the top surface of the sheet, and the sheet is adhered to a desired object by pressing the adhesive band directly against the object. Often, prior to use, a plurality of identical such media are stacked on top of each other and held together using the adhesive bands to form a pad. The media can be stacked with their respective adhesive bands aligned with one another. For such stacks, markings can be made on the top sheet prior to separating the top sheet from the remainder of the pad, or the top sheet can be separated from the pad prior to applying a marking to the separated sheet.
In another type of stack, the media can be arranged in an alternating pattern in which each sheet is rotated 180 degrees relative to its adjacent neighbors with respect to their respective adhesive bands. The aforementioned type of stack is often referred to as an “accordion stack” or as a “Z-stack,” due to the appearance of the stack from its side when the top and bottom sheets of the stack are gently pulled in a direction away from one another. Such stacks can be used in conjunction with a slotted dispenser so that individual sheets can be separated from the stack by pulling the free end of the top sheet up through a narrow slot in the dispenser. Once the sheet has been removed from the dispenser, it can be marked and adhered to a desired substrate. Such stacks can also be used without a dispenser, in which case the marking can be applied to the sheet either before or after separating the sheet from the remainder of the stack.
Another common type of repositionable medium is often referred to in the art as a repositionable flag and includes a rectangular strip of polymeric film divided laterally into a first portion and a second portion, the first portion is usually longer than the second portion. The first portion, which can be translucent, has a repositionable adhesive applied to the bottom surface thereof and has a coating applied to the top surface thereof that is receptive to handwritten or machine-printed markings. The second portion can be devoid of adhesive on its bottom surface and can have a coating over its top surface that is receptive to handwritten or machine-printed markings In addition, the top surface of the second portion can be coated with a colored ink and can additionally include pre-printed information.
The above-described repositionable flags are often arranged in “Z-stacks,” with individual flags being dispensed from the “Z-stack” using a slotted dispenser. In use, a flag is dispensed from the “Z-stack,” and the flag is adhered to a desired object, such as a sheet of paper. If desired, markings can be made on the first portion and/or the second portion of the tape, either before or after the tape is adhered to a desired object. When the desired object is paper, the tape is can be positioned relative to the sheet of paper so that the second portion of the tape extends outside the boundaries of the sheet of paper, with the first portion of the tape positioned within the boundaries of the sheet. In this manner, the second portion can serve as a flag to identify a portion of the paper of interest, with the first portion of the tape being translucent so as not to obscure any printed matter located therebeneath.
Still another common type of repositionable medium includes a sheet of polymeric film divided into a first portion and a second portion, the second portion extending laterally from the first portion as a tab. The first portion, which can be translucent, can have a repositionable adhesive applied to the bottom surface thereof and has a coating applied to the top surface thereof that is receptive to handwritten or machine-printed markings The second portion can be devoid of adhesive on its bottom surface and can have a small sheet of paper, which can be colored, adhered to its top surface, the sheet of paper is receptive to handwritten or machine- printed markings Analogously to the repositionable note flags discussed above, markings can be made on the paper sheet and/or on top of the coated first portion, and the first portion can be adhered to a desired object.
However, in contrast with the aforementioned repositionable note flags, these tabbed media are not arranged in a “Z-stack” prior to use, but rather, are stacked so that all of the first portions of the polymeric film are aligned with one another and so that all of the second portions of the polymeric film are aligned with one another. The reason why a “Z-stack” has not been used for this type of medium is that, if a “Z-stack” arrangement were to be used, the adhesive area on the bottom of a first medium would come into direct contact with the paper portion of a second medium located directly beneath the first medium. Such contact between the adhesive area of the first medium and the paper of the second medium would undesirably result in the delamination or splitting of the paper from the second medium as the first medium is pulled away from the second medium.
It should, therefore, be appreciated that there is a need for a repositionable medium that can resist delamination when removed from a “Z-stack” arrangement. The present invention satisfies this need.
The present invention includes a repositionable medium. The repositionable medium includes a base having a top surface, a bottom surface, a first end edge, and a second end edge.

As used herein, adhesive strength means peel adhesion or tack adhesion as determined by Pressure Sensitive Tape Council test methods PSTC-101 and PSTC-16. According to another approach, this problem can be ameliorated by not providing any adhesive in one or more of the low adhesion areas that can be aligned with one or more of the edges of the paper for the medium positioned thereunder. According to yet another approach, this problem can be ameliorated by providing a release on top of the edges of the paper sheet to inhibit adhesion with the repositionable adhesive of the medium positioned thereover. According to still yet another approach, this problem can be ameliorated by gluing or taping the edges of the paper down to its respective base.

Medium 11 can include a base 13, which is also shown separately in
The first end portion 15 can have a generally trapezoidal shape when viewed from above and can be shaped to include a first side edge 15-1, a second side edge 15-2, and an end edge 15-3. The corner where end edge 15-3 meets first side edge 15-1 and the corner where end edge 15-3 meets second side edge 15-2 can be rounded. In addition, first side edge 15-1 can have a slight concavity 16-1 just before meeting intermediate portion 19, and second side edge 15-2 can have a corresponding concavity 16-2 just before meeting intermediate section 19. Second end portion 17 can have a generally trapezoidal shape when viewed from above and can be shaped to include a first side edge 17-1, a second side edge 17-2, and an end edge 17-3. The corner where end edge 17-3 meets first side edge 17-1 and the corner where end edge 17-3 meets second side edge 17-2 can be rounded.
In addition, first side edge 17-1 can have a slight concavity 18-1 just before meeting intermediate portion 19, and second side edge 17-2 can have a corresponding concavity 18-2 just before meeting intermediate portion 19. Intermediate portion 19 can have a generally rectangular shape when viewed from above and can include a first side edge 19-1 and a second side edge 19-2. Base 13 can be symmetric about both its longitudinal centerline and its lateral centerline, and first end portion 15 and second end portion 17 can be mirror-images of one another.
Exemplary dimensions for base 13 can include a length l1 measured from end edge 15-3 to end edge 17-3 of approximately 38.1 mm and a width w1 measured from side edge 19-1 to side edge 19-2 of approximately 25.4 mm. In addition, each of portions 15 and 17 can have a length l2 of 14.3 mm, and portion 19 can have a length l3 of approximately 10.3 mm.

Medium 11 can also include an overlay 31, which is also shown separately in
Overlay 31 can be a non-translucent material and can include, for example, a sheet of paper 35 that is receptive to handwritten markings, such as those made, for example, by pen, marker and/or pencil, and/or to machine-printed markings, such as those made, for example, by typewriter and/or printer. Paper 35 can include colored paper or white paper and can be either coated or uncoated. A writable release coating 37 can be applied to at least a portion of the top surface of paper 35 to minimize adhesion of overlay 31 to a repositionable adhesive of another medium 11 brought into contact therewith.
Referring back to
In this manner, as will be seen below, in a “Z-stack” of two or more media 11, adjacent media 11 will be arranged so that the inner edge 31-4 of overlay 31 of the lower medium 11 is aligned between outer edge 41-3 and inner edge 41-4 of the upper medium 11. Where medium 11 has the dimensions discussed above, outer edge 41-3 and inner edge 41-4 can be spaced apart from one another by a distance of, for example, approximately 3.0 mm. In other embodiments, outer edge 41-3 and inner edge 41-4 can be spaced apart from one another by a distance ranging from approximately 2.0 mm to approximately 5.0 mm.
Adhesive patch 43, which can include a coating of a relatively high-tack repositionable or ultraremovable adhesive, can have boundaries including a first side edge 43-1, a second side edge 43-2, an outer edge 43-3, and an inner edge 43-4. First side edge 43-1 can lie substantially flush with a portion of first side edge 17-1 of base 13, second side edge 43-2 can lie substantially flush with a portion of second side edge 17-2 of base 13, outer edge 43-3 can lie substantially flush with end edge 17-3 of base, and inner edge 43-4 can lie substantially flush with outer edge 41-3 of patch 41. The first side edge 43-1, second side edge 43-2, outer edge 43-3, and inner edge 43-4 also define a first high adhesion area.
Adhesive patch 45, which can be identical in composition to adhesive patch 43 and which can include a coating of a relatively high-tack repositionable or ultraremovable adhesive, can cover a second high adhesion area on the bottom surface of base 13 extending laterally substantially the full width of base 13 and extending longitudinally from inner edge 41-4 to a boundary 45-1 substantially aligned with inner edge 31-4 of overlay 31. Boundary 45-1 is located a distance, a fifth distance, from the first end edge 15-3, and the distance is greater than length l4.
As discussed above, adhesive patch 43 and adhesive patch 45 can include relatively high-tack repositionable or ultraremovable adhesives, and adhesive patch 41 can include a relatively low-tack repositionable or ultraremovable adhesive. It should be understood that adhesive patches 41, 43, and 45 can include the same repositionable or ultraremovable adhesive that is detackified or pattern-coated to provide the necessary relative tack required for each patch. Alternatively, adhesive patch 41 can be a lower coat weight of the same adhesive used for adhesive patch 43 or adhesive patch 45. In one embodiment, the coat weight of adhesive patches 43 and 45 can range between approximately 5.5 grams/square meter (gsm) to approximately 6.5 gsm, and the coat weight of adhesive patch 41 can range between approximately 5.5 gsm to approximately 6.5 gsm. In other embodiments, the coat weight of adhesive patches 43 and 45 can range between approximately 3 gsm to approximately 12 gsm, and the coat weight of adhesive patch 41 can range between approximately 3 gsm to approximately 12 gsm.
Ultraremovable adhesives are discussed in the following patents and patent publications, all of which are incorporated herein by reference herein in their entireties: U.S. Pat. No. 6,328,518 to Wong, issued Dec. 11, 2001; U.S. Pat. No. 6,315,851 to Mazurek et al., issued Nov. 13, 2001; U.S. Pat. No. 5,656,705 to Mallya et al., issued Aug. 12, 1997; and U.S. Patent Application Publication No. US 2002/0047263 A1 to McCarthy et al., published Apr. 25, 2002. Additionally, a primer can be used with removable or ultraremovable adhesives to increase the anchorage of the adhesive to the base.

As can be seen, to dispense the uppermost medium 11-1 from dispenser 61, a user can pull the exposed end of medium 11-1 away from the remainder of “Z-stack” 51, for example, by pulling the combination of end portion 15 of base 13 and overlay 31 of medium 11-1 through slot 61-1 in the direction indicated by arrow A. Although overlay 31 of middle medium 11-2 is in contact with adhesive on the bottom of uppermost medium 11-1, the separation of uppermost medium 11-1 from the remainder of “Z-stack” 51 is less likely to result in the delamination of overlay 31 from middle medium 11-2 than would otherwise be the case. This is because inner edge 31-4 of overlay 31 of middle medium 11-2 is in contact with adhesive patch 41 of uppermost medium 11, adhesive patch 41 is relatively low-tack, as compared to adhesive patches 43 or 45. Since the initiation of delamination is most likely to occur along inner edge 31-4 of overlay 31 when pulling medium 11-1 in the direction indicated by arrow A, the reduction in adhesion between 31 and medium 11-1 due to the use of adhesive patch 41, instead of the use of an adhesive similar to that of patches 43 and 45, is likely to result in a reduction in the occurrence of delamination.
Medium 11 can be marked and/or applied to objects in the conventional fashion. Referring now to
Medium 111 can be similar in most respects to medium 11, the principal difference between the two media being that, in medium 111, the area occupied by patch 43 of medium 11 can be occupied with the combination of an adhesive patch 112, occupying the first high adhesion area, and an adhesive patch 113, adhesive patch 113 extending along edge 17-3 of base 13 and occupying a second low adhesion area. Adhesive patch 112 can be identical in composition to adhesive patch 43 and can include a relatively high-tack repositionable or ultraremovable adhesive. Adhesive patch 113 can be identical in composition to adhesive patch 41 and can include a relatively low-tack repositionable or ultraremovable adhesive. Patch 113 can serve to inhibit the initiation of delamination along outer edge 31-3 of overlay 31.
Medium 111 can be stacked, dispensed, marked, and/or adhered to an object analogously to medium 11.

Medium 211 can be similar in most respects to medium 111, the principal difference between the two media being that, in medium 211, no adhesive is positioned in the corresponding areas occupied by patches 41 and 113 of medium 111. Instead, medium 211 can include a first non-adhesive area 213 provided in the area corresponding to patch 41 of medium 11, and a second non-adhesive area 215 can be provided in the area corresponding to patch 113 of medium 11. In another embodiment (not shown), second non-adhesive area 215 can be occupied with an adhesive similar to that of patch 41 or similar to that of patches 43 and 45, with first non-adhesive area 213 remaining unoccupied by adhesive.
Medium 211 can be stacked, dispensed, marked, and/or adhered to an object analogously to medium 11.

Medium 311 can be similar in most respects to medium 11, the principal difference between the two media being that adhesive patches 41 and 43 of medium 11 can be replaced in medium 311 with an adhesive patch 313. Adhesive patch 313 can be identical in composition to adhesive patch 41 and can include a relatively low-tack repositionable or ultraremovable adhesive.
Medium 311 can be stacked, dispensed, marked, and/or adhered to an object analogously to medium 11.

Medium 411 can be similar in most respects to medium 211, the principal difference between the two media being that patches 45, 213 and 112 of medium 211 can be replaced in medium 411 with an adhesive patch 413. Patch 413 can include an adhesive similar to that of patch 45 of medium 211.
Medium 411 can be stacked, dispensed, marked, and/or adhered to an object analogously to medium 11.

Medium 511 can be similar in many respects to medium 11. One difference between the two media can be that medium 511 can include a single adhesive patch 513 covering the areas corresponding to the areas covered by patches 41, 43 and 45 of medium 11. Patch 513 can include a repositionable or ultraremovable adhesive similar to that of patches 43 and 45 of medium 11. Another difference between medium 511 and medium 11 can be that medium 511 can further include a strip of non-adhesive coating 517, for example, a lacquer coating, positioned over inner edge 31-4 (shown in phantom) of overlay 31, with a first edge 517-1 of non-adhesive coating 517 adhered to overlay 31 and with a second edge 517-2 of non-adhesive coating 517 adhered to base 13. Non-adhesive coating 517 can serve to inhibit the initiation of delamination of overlay 31 along inner edge 517-1. As can be appreciated, non-adhesive coating 517 could be replaced with other non-adhesive means, such as, for example, a single-sided adhesive tape.
Medium 511 can be stacked, dispensed, marked, and/or adhered to an object analogously to medium 11.

Medium 611 can be similar in many respects to medium 11. One difference between the two media can be that medium 611 can include a single adhesive patch 613 covering the areas corresponding to the areas covered by patches 41, 43 and 45 of medium 11. Patch 613 can include a repositionable or ultraremovable adhesive similar to that of patches 43 and 45 of medium 11. Another difference between medium 611 and medium 11 can be that medium 611 can include an overlay 615, instead of overlay 31 of medium 11. Overlay 615 can differ from overlay 31 in that, whereas overlay 31 can include a writable release coating 37 applied over the entire top surface of paper sheet 35, overlay 615 does not include a writable release coating applied over the entire top surface of its paper sheet 617, but rather, can include a first band 619-1 of a writable release coating applied to the top surface of paper sheet 617 along an inner edge 617-1 of sheet 617 and a second band 619-2 of a writable release coating applied to the top surface of paper sheet 617 along an outer edge 617-2 of sheet 617. Bands 619-1 and 619-2 of the release coating can reduce adhesion between the overlay 615 of a first medium 611 and adhesive patch 613 on the bottom of a second medium 611 positioned directly thereover and, in so doing, can serve to inhibit the initiation of delamination of overlay 615 along inner edge 617-1 and/or along outer edge 617-2.
As can be appreciated, additional bands of the release coating can also be applied to the top surface of paper sheet 617 along each of its two side edges, thereby forming a frame around the perimeter of sheet 617, to inhibit the initiation of delamination of overlay 615 along either of its side edges.
