Definitions

  • the invention provides a series of solutions to the theft of personal, medical and industrial information.
  • the invention comprises a printable surface called a coversheet.
  • the coversheet is partitioned into a series of releasable island cutouts and a residual framework, such that the integrity of the page is maintained, but each cutout can be released from the page using only minimal force, due to the presence of the cuts or perforations.
  • the coversheet is overlain or underlain with two additional sheets, a separator and a topsheet, which together comprise the release unit.
  • the separator sheet has a series of small holes which are positioned to overlay the cutouts on the coversheet, the topsheet is attached through the holes of the separator to the cutouts of the coversheet, and in some embodiments may help anchor these cutouts in place.
  • the separator and topsheet are adhered to each other at their periphery and have tabs at one or both ends, a removal tab on the separator, and an initiation tab on the topsheet.
  • the separator can also be adhered at its periphery to the coversheet to hold the release unit in place. To destroy the document, the release unit is first liberated from the coversheet using the removal tab, causing the perforated cutouts to detach from the coversheet due to their attachment to the topsheet.
  • the topsheet is then released from the separator using the initiation tab. As the attached cutouts are larger than the holes of the separator, the shear force breaks the anchor bonds holding the topsheet to the cutouts, and individual cutouts are released as chads. Each chad contains a fraction of the original document information, ensuring complete obliteration of the original document data. In some embodiments the coversheet is fully perforated and the cutouts are held in place by their attachments to the topsheet.
  • release of the coversheet cutouts will reveal information contained on one or more of the other layers.
  • the coversheet is adhered to an adhesive backing sheet with an optional release liner, allowing it to be affixed to items as desired.
  • the instant invention renders destruction of the printed surface and obliteration of any readable text. Further details and embodiments are discussed below.
  • the invention comprises the following elements:
  • a first element of the invention comprises one or more coversheets.
  • the coversheet is typically a piece of paper, plastic, polymer, cloth, metal, or other suitable material.
  • One surface comprises a writable or printable surface, on which hand writing, printing, graphics, mailing and other information can be entered.
  • the text may be applied to the coversheet through one or more overlying layers using thermal printing.
  • both surfaces may be writable.
  • the coversheet is cut or perforated with a series of island outlines or "cutouts" using methods such as die or laser cutting well known in the art and commonly employed in the production of stickers, adhesive labels, stamps, toilet paper etc.
  • the coversheet may be slightly perforated, such that significant force is required to dislodge the cutouts, or any variation up to fully perforated such the cutouts are free floating and may be held in place by their attachment to the topsheet.
  • the cutouts may be the same or different shapes and sizes, and their patterning on the coversheet may be uniform or random, and may cover all or a part of the coversheet. Dimensions, sizes and shapes of the cutouts will depend on font type, font characters and font size, document format etc, and can be chosen to maximize data masking. Typical cryptographic methods of obscuring the information can be employed to optimize these parameters to ensure the information is indeterminate after destruction and cannot forensically be reassembled.
  • the remaining portion of the coversheet is known as the residual framework.
  • the coversheet is adhered to an underlying adhesive or non-adhesive backing sheet with optional release liner.
  • the backing sheet is transparent.
  • the cutting or perforation shall usually be such that the cutouts are substantially separated from the coversheets, but the integrity of the page is maintained, and each cutout can be released from the page using only minimal force due to the presence of the perforations.
  • the cuts/perforations may be such that the cutouts are more easily released from the backing and coversheets to leave the residual coversheet lattice affixed to the underlying backing sheet.
  • the coversheet may be akin to a perforated sticker and the coversheet's lower surface is covered in an adhesive which can form a releasable bond with the underlying upper surface of the backing sheet, which is formulated as a release layer as further described below.
  • the coversheet further comprises one or more tabs at one or each end, which can serve to fasten the coversheet ends, act as finger holds to facilitate separation of layers from each other, or which can be gripped to facilitate pulling of the coversheet.
  • the tab may be any shape and conformation suitable for gripping, and may be integral to the coversheet, comprising a flattened and reinforced section. It may additionally comprise a mechanism to secure the free end.
  • a second element of the invention comprises one or more separator sheets, or separators, which incorporate a pattern of small holes that overlap each cutout on the coversheet. These holes may be of any shape and size and overlay the cutouts allowing the topsheet to be spot adhered to the cutouts.
  • the separator is usually, but not always, transparent, and acts to sever the connection between the topsheet and the cutouts following their release from the coversheet, discharging them as chads.
  • the separator may be equal to or smaller in size than the topsheet, but in any case, at least large enough to cover the attachments to the cutouts.
  • the separator may be permanently or temporarily adhered in one or more places and on one or both sides, so as to form attachments with the topsheet and/or coversheet residual framework.
  • the separator may have no peripheral adhesion and be held in place by the bonds between the topsheet and coversheet cutouts.
  • the separator usually has a removal tab at one or both ends which can be gripped to facilitate separation from the other elements of the invention and document destruction.
  • the tab may be any shape and conformation suitable for gripping, and may be integral to the separator, comprising a flattened and reinforced section.
  • the removal tab is positioned at the opposite end to the release tab and may be offset with respect to the topsheet or coversheet. It may additionally comprise a mechanism to secure the free end.
  • a third element comprises one or more topsheets, which at least completely covers each of the holes on the separator, and is anchored to the each of the cutouts through the holes of the intervening separator.
  • This attachment may be through any suitable means, and may include spot or other adhesion, fusion or any chemical or mechanical bonding methods.
  • the attachment may be of any size, shape and number such that the cutouts are firmly anchored through the holes to the topsheet without adhering to the intervening separator.
  • the topsheet will typically be a sheet, composed of any suitable material and will typically, but not always, be transparent.
  • the topsheet further comprises one or more release tabs at one or each end similar to the tabs described previously, which act as finger holds to facilitate detachment of the topsheet from the other layers.
  • the release tab is positioned at the opposite end to the removal tab and may be offset with respect to the separator or coversheet. Pulling the topsheet away from the separator using the release tab breaks the bonds to the cutouts resulting in their release as chads.
  • the topsheet is adhered peripherally directly to the coversheet residual framework, and the separator is held in place by the anchors between the topsheet and cutouts.
  • the coversheet is fully perforated and the cutouts are held in place by their anchors to the topsheet layer.
  • a fourth optional element of the invention comprises a backing sheet and optional release liner.
  • the backing sheet comprises an upper surface to which a coversheet can be adhered.
  • the upper surface has the properties of a release liner, i.e. coated with polyolefins such as HDPE, LDPE and PP plastic resins, silicon, polyvinyl alcohol or other suitable components, which may cover all or part of the backing sheet and allows a reliable but temporary bond to the lower surface of the coversheet. This facilitates sticking to the coversheet, but allows subsequent release of the perforated cutouts from the upper surface of the backing sheet.
  • the backing sheet has no adhesive applied to its lower surface, and acts to strengthen the overlaying coversheet by bonding thereto.
  • the lower surface of the backing sheet comprises a second adhesive surface capable of affixing to a mailing or other surface and is usually protected by a release liner.
  • the lower surface may be coated in an adhesive, with or without an optional release liner, and can be adhered to a mailing or other surface by any of those techniques known in the art.
  • the lower surface may typically comprise a simple sticker, with a pressure sensitive adhesive covering the surface. The adhesive is protected by a release liner, to safeguard the adhesive prior to the label being applied as is common in the sticker industry.
  • the release liner comprises an upper surface which is coated with silicon, polyvinyl alcohol or other suitable components, to reduce the stickiness of the surface, and allow a reliable but temporary bond to a second adhesive coated surface.
  • the attached release liner can be peeled away from the backing sheet to expose the adhesive covered lower surface to facilitate affixing to a mailing or other surface.
  • the adhesive on the lower surface of the backing sheet may be uncovered, and require activation by water, light, temperature or other means known in the art, and in this instance the optional release liner may be omitted.
  • coversheet, backing sheet and release liner are composed of papers or cardboards, e.g. any pulp of wood or other fibrous products as known in the art. In some embodiments these elements are composed of cloth or other woven materials. Alternatively plastics and other organic polymers may be used. In certain applications metallic foils and alloys may also be advantageous.
  • thermal active materials and thermal printing may be employed to print through overlying layers.
  • Thermal printing produces a printed image by selectively heating coated thermochromic paper, or thermal paper and can be used to create an image on a sheet through overlying or underlying layers. The coating changes color in the areas where it is heated, producing an image in one or more colors.
  • thermal transfer, laser, inkjet or any other form of printing may be employed. Text and images may be applied prior to, during, or subsequent to roll-to-roll combination of the layers, and may appear on either side of any layer, depending on the embodiment.
  • the topsheet may also be composed of the above materials and may be the same or different material to the coversheet. Likewise the separator and tab may be constructed from the variety of materials listed above. In many applications one or more layers will be constructed from a transparent material. Preferred materials may be stored and utilized in a roll format to facilitate easy manufacturing.
  • the adhesive may be of any type commonly used in the production of stickers and labels.
  • the adhesive may be permanent, peel able or high tack.
  • the adhesive chosen for each of the surfaces will best suit the task at hand. For instance, a relatively strong bond is needed between the backing sheet and the mailing to ensure fastening, while a relatively weaker bond might be employed between the backing sheet and coversheet so as to facilitate easy release of the cutouts upon pulling of the topsheet. Any materials and method known in the art which produces a firm bond of the lower surface to a mailing, and a releasable bond between the upper surface and coversheet is contemplated within the scope of the instant invention.
  • coversheet will be slightly perforated such that the cutouts are firmly attached to the coversheet and require a shear force between the separator and coversheet to facilitate removal.
  • coversheet may be fully perforated such that the cutouts are for all purposes separated from the coversheet and may be held in place by their anchors to the topsheet. This may be achieved using laser cutting during the converting stage of the roll-to-roll process following combination of the layers and spot adhesion of the cutouts to the topsheet.
  • the invention provides significant improvements for easy manufacturing using current techniques compared to other solutions in the art.
  • label manufacturers employ roll-to-roll processing, also known as reel-to-reel processing or R2R, and utilize continuous sheets of flexible materials (called webs) that are rolled up for more convenient handling and transportation.
  • Materials such as paper, cloth, plastic film and foils of various weights and lengths can hence be employed in processing machines such as printing presses, laminating, coating and cutting/perforating machines to create an intermediate or final product.
  • each layer of the label is contained on a roll and the layers are combined and manipulated in a process known as converting. Individual rolls of each layer are presented to the machine and are bonded as dictated by the embodiment using chemical, mechanical, thermal, adhesive or other means.
  • the use of layers allows for customization of label embodiments such as pre-printing, use of thermal active materials for later application of information, and selection of different materials and transparencies for different layers.
  • the combined layers can be re-reeled to create an output roll or can be further processed on the same or a different machine depending on the application.
  • Common converting techniques include die cutting, laser cutting or other suitable perforation/cutting techniques, and thermal or conventional printing.
  • Common finishing techniques include techniques well known in the art such as slitting, sheeting, fan-folding, scoring or other processes to provide a customized completed label.
  • the instant invention has the advantage that all elements can be contained on rolls and processed through equipment currently utilized and economically competitive in the label making industry.
  • each invention element may be customized with final print and perforation already applied so the rolls can be simply combined and then cut or processed for distribution.
  • the inputs may be blank and ready for customized data input and/or perforation during or following the layer combination process. This imparts a flexibility for a variety of solutions. To employ other materials such as tapes or filaments, solid tabs and cutting devices, requires specialized machinery and expertise not currently found in the marketplace.

Following bonding, the combined layers can be re-reeled to create an output roll or can be further processed (converted) on the same or a different machine depending on the application. Common converting techniques include die cutting, laser cutting or other suitable perforation/cutting techniques, and thermal or conventional printing.
  • Common finishing techniques include techniques well known in the art such as slitting, sheeting, fan-folding, scoring or other processes to provide a customized completed label.
  • the coversheet is pre-printed, while in others a roll of thermal active materials is employed so that information can be applied at a later time.
  • backing sheet with release liner are omitted.
  • the topsheet and separator may be supplied as transparent rolls.
  • the coversheet is fully perforated using precision laser, after the cutouts have been anchored to the topsheet.
  • the instant invention has the advantage that all elements can be contained on rolls and processed through equipment currently utilized and economically competitive in the label making industry.
  • each invention element may be customized ready for lamination of a final product, or blank and ready for customized data and perforation during or following the lamination process. This imparts a flexibility for a variety of solutions. To employ other materials such as tapes or filaments, solid tabs and cutting devices, requires specialized machinery and expertise not currently found in the marketplace.
