  • the multi-layer sheet of individual posting sheetlets of the invention is particularly useful in a home setting and in an office setting. It is, for this reason, described in these settings in the following paragraphs. It can as well be used in an industrial setting or wherever there is a need to temporarily post a lightweight item for referencing purposes .
  • FIG. 1 shows a multi-layer sheet of several individual posting sheetlets
  • FIGS. 9-11 show a use of an individual posting sheetlet taken from the multi-layer sheet.
  • a multi-layer sheet 10 of the invention is comprised of a plurality of individual uniformly shaped posting sheetlets 11 in substantially flat sheet form.
  • the posting sheetlets 11 are in a side-by-side relationship to form a first column 12 of twelve posting sheetlets and a second column 13 of twelve posting sheetlets.
  • the collective twenty-four posting sheetlets represent a full sheet 16.
  • a vertical severance line 17 (seen in FIG. 4) extends vertically down the middle of the sheet 16 to form the two columns.
  • horizontal severance lines 18 extend from the vertical severance line 17 to opposed peripheral edges of the full sheet 16.
  • a base release sheet 14 and a removable cover sheet 15 are included on bottom and top respectively of the posting sheetlets for packing reasons.
  • the base release sheet 14 normally remains in place until the multilayer sheet is depleted of its individual posting sheetlets.
  • the removable cover sheet 15 is scored or perforated for separation of cover panels 19 from the balance of the cover sheet and from the individual posting sheetlets as each is used.
  • the individual posting sheetlets 11, base release sheet 14 and removable cover sheet 15 in the multi-layer sheet 10 are discussed in more detail in the following paragraphs.
  • the size and shape of the full sheet 16 made up of the individual posting sheetlets 11 are not critical.
  • the full sheet 16 and the individual posting sheetlets 11 are both preferably rectangular- shaped or square-shaped. As shown in FIG. 1, each posting sheetlet 11 is rectangular-shape and all the posting sheetlets are equally sized. If desired, the posting sheetlets in one column can be one size and the posting sheetlets in the other column can be another size, provided the full sheet is still rectangular-or-square- shaped.
  • Severance lines 17 and 18 and peripheral edges of the full sheet 16 define the individual posting sheetlets 11. The severance lines can be perforated for easy tearing or full cuts, extending fully through the sheet 16.
  • Each posting sheetlet 11 ranges from about one-fourth inch to about six inches in width, as measured along the columns and about one inch to about five inches in length, as measured from the vertical severance line 17 to a peripheral edge.
  • a preferred posting sheetlet ranges from about one-fourth inch to about one and one-half inch in width and about one inch to about three inches in length.
  • the narrow width of the preferred posting sheetlet is feasible because of the adhesive used in the invention. Posting sheetlets with the narrow width are preferred due to reduced manufacturing costs, enhanced ease of use by the consumer, and desired inconspicuous product use. Larger sized posting sheetlets are feasible, dependent only on the intended use and are contemplated in this invention. Such larger sized posting sheetlets, though, tend to be for very specialized uses as found in an industrial setting.
  • Each posting sheetlet 11 in the multi-layer sheet 10 has opposed adhesive-bearing surfaces.
  • an individual posting sheetlet 11 taken from the multi-layer sheet 10 has a front face 20 with an adhesive 21 covering a portion of it and a back face 22, also with an adhesive 23 covering a portion of it.
  • the front face 20 and the back face 22 are facing in opposite directions.
  • a posting sheetlet taken from the other column of the full sheet is identical, other than its adhesive-free area being on the opposite side.
  • the adhesives 21 and 23 on the individual posting sheetlets 11 partially cover the respective front face 20 and back face 22 and are firmly adhered thereto.
  • the adhesives are depicted in FIGS. 4 and 7 as defined layers, though it should be understood the layers may have varying thicknesses and continuity throughout. It is important for the adhesive to not fully cover the faces in that the individual posting sheetlets are then more difficult to grasp and to remove from the multi-layer sheet during use.
  • the adhesives 21 and 23 are positioned on approximate aligned areas of the respective faces of the posting sheetlets 11.
  • each adhesive on the posting sheetlets extends fully across the width of the faces, from side edge 26 to side edge 27.
  • each adhesive also extends continuously down from the top edge 24 to about 70% to about 95% of the posting sheetlet 's length, more preferably from about 80% to about 90% of the sheet's length to terminate inwardly of the bottom edge 25.
  • a termination line is created which is substantially parallel with the bottom edge 25.
  • An adhesive-free area 28 of about one-quarter inch to about three-quarters inch at the bottom of the posting sheetlet on both sides is created as a handle for grasping purposes. It has been found the preferred adhesive placement optimizes removal of posting individual sheetlets from the multi-layer sheet and actual use of the individual posting sheetlets.
  • Posting sheetlets which are fully covered on both sides by an adhesive are difficult to individually grasp and remove from the multi-layer sheet. Conversely, too small of an adhesive area will adversely affect the ability of the individual posting sheetlet to adhere to a substrate and/or to adequately hold an item to be posted.
  • the adhesive must have a degree of adhesion sufficient to stick to a substrate and an item to be posted, yet be releasable. Additionally, the adhesive must not leave a sticky residue.
  • Pressure sensitive adhesives are commercially available and ideally suited herein. Highly preferred are hot melt adhesives and water- based acrylic adhesives which are applied as microspheres onto the posting sheetlets. The adhesive is applied at a level to give a dried adhesive of from about 0.4 mil to about 0.8 mil, preferably about 0.6 mil in thickness. Application of the adhesive as microspheres on properly sized paper is done by conventional well known methods .
  • the acrylic adhesive when applied as microspheres and at the proper thickness results in a degree of adhesion of from about 100 grams to about 150 grams per linear inch, preferably about 125 grams to about 135 grams per linear inch using test criteria published by the Pressure Sensitive Test Council (PSTC-1) . It is theorized that the proper degree of adhesion results from the form of the adhesive, i.e. microspheres as opposed to a coalesced film, and proper thickness of adhesive, i.e. about 0.4 mils to about 0.8 mils.
  • PSTC-1 Pressure Sensitive Test Council
  • each full sheet of the multi-layer sheet has at least about six individual posting sheetlets.
  • the base release sheet 14 and the removable cover sheet 15 are releasably attached to the full sheet 16 of individual posting sheetlets 11.
  • the base release sheet 14 is releasably attached, through the adhesive on the back face of the posting sheetlets .
  • the base release sheet 14 has a size and shape substantially equal to that of the full sheet 16 of individual posting sheetlets.
  • the removable cover sheet 15 is releasably attached to the several posting sheetlets through the front face adhesive on the individual posting sheetlets.
  • the removable cover sheet has a size and a shape to completely cover the upper layer of pressure- sensitive adhesive on the full sheet of posting sheetlets and to extend at least partially, preferably fully, over the adhesive-free area of the front face of the posting sheetlets.
  • the removable cover sheet 15 is scored to create multiple cover panels 19. Each cover panel 19 substantially coincides in size and shape with an underlying individual posting sheetlet 11.
  • the resulting severance lines 29 can be perforations as shown which require some tearing to fully remove a cover panel 19 from the balance of the cover sheet 15.
  • the severance lines can be continuous and fully cut so that a mere lifting of one of the cover panels 19 is all that is required to reveal the underlying individual posting sheetlet 11.
  • Release substrates of various natures are commercially available and are used in the invention for the base release sheet and removable cover sheet.
  • either sheet can be a wax coated paper sheet, silicone-coated paper sheet, or a plastic sheet such as a polyethylene terephthalate (available as Mylar sheet) or any other plastic sheet made from synthetic polymeric resin with non-stick physical characteristics.
  • Highly preferred base release sheets and cover sheets are made from supercalendered kraft paper which has been silicone coated on both sides.
  • FIG. 8 depicts a multi-layer sheet 35 of the invention having larger sized individual posting sheetlets 36. As shown, there are two columns of posting sheetlets, each having three individual posting sheetlets. Each posting sheetlet is about one inch to about three inches in width and about two inches to about four inches in length. The adhesive areas on the posting sheetlets extend about 70% to about 95% of the posting sheetlet 's length with an adhesive-free area 37 at each bottom edge on both sides. A base release sheet 38 and a removable cover sheet 39 are as described above with respect to FIGS. 1-4.
  • the home owner or office worker who desires to post an item simply grasps an individual posting sheetlet from the multi- layer sheet and pulls it therefrom.
  • An overlying cover panel is either removed prior to separating the posting sheetlet from the multi-layer sheet or subsequent to the posting sheetlet being removed.
  • the posting sheetlet is then placed on a substrate in a convenient location. Either face of the posting sheet can be adhered to the substrate with the opposed face exposed for further use. It can be used as is by writing on it.
  • an item such as an envelope to be posted is placed in contact with the adhesive on the opposed face of the posting sheetlet . It remains there for an indefinite time.
  • the homeowner or office worker removes the item and reuses the posting sheetlet or simply removes and discards it also.
  • the home owner or office worker simply removes and discards one of the other scored cover sheet panels to expose the next posting sheetlet. That posting sheetlet is removed from the multi-layer sheet and used as described above with respect to the first posting sheetlet .
  • the multi-layer posting sheetlet of the invention can be modified in various manners for specialized uses.
  • the degree of adhesion of the adhesive on the back face can be greater than the degree of adhesion on the front face of each individual posting sheetlet to better ensure that removal of a posted item from a sheet adhered to a surface will leave the sheetlet in place.
  • the adhesive-free areas of each posting sheetlet can be sufficiently large to receive penciled or penned notes. Still other features to enhance the multi-layer sheet's marketing appeal are feasible, e.g. color-coded sheetlets, etc.
