Definitions

  • the present invention relates to reinforced file folders and in particular, relates to reinforced file folders having improved durability and improved characteristics with respect to writing thereon.
  • each file folder is specific to a particular client or subject.
  • the file folders have labeling tabs to which subject or client specific labels are secured.
  • the file folders can include traditional top labeling tabs or lateral tabs for side tab filing.
  • Canadian Patent 1,197,155 discloses a reinforced file folder where the labeling tab of the file folder has been reinforced with a mylar reinforcing film. This reinforcing film is applied along one edge of the folder length and the edge of the folder is then folded upon itself and adhered. The folder edge is then die cut to form the labeling tab.
  • This labeling tab has a reinforcing film on the exterior thereof and the film provides a smooth surface for receiving pressure sensitive labels.
  • the reinforcing film has a polyethylene outer surface and an underlying thermally activated polypropylene layer.
  • the file folder according to this prior patent has proven particularly successful in reinforcing the file folder adjacent the labeling tab such that the tab is not particularly prone to damage. Multi layer pressure sensitive labels having a similar polyethylene outer layer are commonly used to improve the appearance and durability of the labels.
  • the front and/or back surfaces of the file folder are used to provide handwritten summary type information or a log of how the file has been used or reviewed.
  • the front of the file can be used for signatures of the various people who have withdrawn the file at a particular point in time or can include more detailed client information which can be recorded on the file folder.
  • a composite file folder comprises a front panel, a back panel and a labeling tab along one edge of the back panel with the back and front panels being integrally joined along one edge with a fold axis between the panels.
  • the folder has a paper substrate support layer with a reinforcing film adhered to the exterior surfaces of the front and back panels across the fold axis and applied either side of the labeling tab.
  • the reinforcing film is a multi layer film having a matte finish outer surface and an underlying adhesive inner layer adhered to the folder.
  • the reinforcing film covers at least 50% of the outside surface of the file folder. This reinforcing film provides an excellent surface for receiving printed indicia on the matte finish outer surface.
  • the printed indicia is to be permanently bonded to the finished surface, a curable ink can be used.
  • the matte finish allows user recordal of indicia using a ballpoint pen or lead pencil. This indicia is not prone to smudging, however, it can be manually removed if desired using a traditional rubber eraser.
  • the file folder can be reconditioned by removing of any indicia which is specific to the former use of the file folder.
  • the reinforcing film not only reinforces the tab but also provides a reconditionable writing surface on the file folder.
  • the outer layer of the reinforcing film is a cellulous base material.
  • the preferred film is an acetate.
  • the reinforcing film is a breathable cellulose base material.
  • the present invention is also directed to a file folder comprising a body of paper stock and an exterior film substrate secured to the paper stock.
  • the file folder has a front face and a rear face joined along a fold line.
  • the front face is of a length to cooperate with the back face to form a labeling tab which extends beyond a marginal edge of the front face.
  • the film substrate is secured to cover the exterior surface of the file folder and to cover both sides of the labeling tab.
  • the film substrate comprises an underlying adhesive layer and an overlying cellulous based layer where the adhesive layer secures the film to the paper stock.
  • the cellulous based layer has a treated surface finish which varies the depth of the overlying cellulous layer. This treated surface finish has superior properties with respect to receiving and retaining ink from ballpoint pens or receiving lead from pencils.
  • the film substrate is at least partially translucent and the paper stock has been printed thereon with the print on the paper stock being visible through the film substrate.
  • the paper stock has been printed with general information and/or category information to be used in assisting a user to enter specific summary information with respect to the contents of the file folder.
  • the specific summary information is manually written or printed on the surface of the film substrate.
  • the preferred printing on the film for permanent marking is printed using a printer using UV curable ink. Printing on the surface provides excellent clarity.
  • the manually written or printed indicia on the surface of the film substrate are removable using a suitable eraser.
  • the surface treated cellulous based layer provides an excellent receptor surface which provides strong adhesion with pressure sensitive labels such that the labels remain adhered to this layer during normal use of the file folder while allowing these labels to be removed if the file is to be reconditioned for a new application.
  • the paper stock 2 shown in Figure 1 passes beneath a printing roller 4 which prints the indicia 6 on the surface of the paper stock.
  • this printed indicia 6 is applied only to the outside surface of the front face of a file folder, however, it can be applied to both the front and back surfaces.
  • the paper stock 2 can be printed at least on the outer surface to define certain general category type information that is desirable for a particular purchaser or industry.
  • the paper stock is a cellulous material and reacts to different levels of humidity. In the past, changes in humidity have lead to label adhesion problems.
  • Previously used polyethylene films provide reinforcement and better label securement. The ability to print indicia or manually write on this film is poor. This type of film has a smooth surface to enhance securement but manually written indicia tends to smudge.
  • Figure 2 shows a file folder blank which has been printed on the exterior surface with industry specific information.
  • This file folder has particular application for government, legal, financial, medical and insurance industries where writing on the surface of the file folder is advantageous.
  • the increased desirability in combination with the ability to custom print on or under the film makes the file folder suitable for financial, manufacturing, education or resource applications.
  • FIG 3 shows the application of a reinforcing film substrate 12 applied to the paper stock 2 over the printed indicia 6 using the application roller 10.
  • the film substrate 12 is preferably a transparent cellulous based material such that the printed indicia 6 are visible through the film.
  • the film has a treated surface, preferably a matte finish 18 which provides an excellent surface for temporarily receiving user recorded information on the surface of a file folder.
  • the application of the reinforcing film substrate 12 is simplified by having the edge 15 of the film aligned with the edge 17 of the paper stock 2.
  • the opposite edge 19 of the reinforcing film falls slightly short of the opposite edge 21 of the paper stock. With this arrangement, the reinforcing film substrate 12 is aligned with the edge 17 and is within the area of the paper stock.
  • the reinforcing film can also be a polyethylene layer with a matte or textured surface having an appropriate adhesive for securement to the paper substrate.
  • a heat activated polypropylene layer or a U.V. curable adhesive function satisfactorily.
  • Reinforcing films having a pressure sensitive adhesive and a silicon release film are not appropriate.
  • the covered paper stock has a small border edge 14 as shown in Figure 4 which is not covered by the reinforcing film substrate 12. This edge of the paper stock is folded rover upon itself and as such, the border edge 14 will be protected within the file folder.
  • FIG. 5 shows the printed paper stock 2 with the film substrate 12 secured thereto and the paper stock folded upon itself to produce the reinforced edge 20.
  • the film substrate has an outer breathable layer and a lower adhesive layer.
  • the adhesive layer is thermally activated by heat being applied to the breathable layer using the roller 10 which raises the temperature of the films to activate the underlying adhesive layer without damaging the upper layer.
  • cellulous based reinforcing film is secured to the paper stock.
  • the cellulose acetate reinforcing film functions particularly well with an ethylene vinyl acetate (EVA) adhesive.
  • EVA ethylene vinyl acetate
  • Figure 6 is similar to Figure 5 , however, the combined paper stock and film has been die cut to form a file folder 23 with a front panel 23a and a rear panel 23b.
  • This file folder 23 has a reinforced edge 22, a labeling tab 24 and a fold line 28.
  • the file folder has the reinforcing film substrate secured to the exterior surfaces of the file folder and wrapped about the labeling tab 24. This arrangement reinforces the labeling tab 24, reinforces the junction 25 between the labeling tab 24 and the reduced edge 27 and provides a file folder having excellent durability.
  • the exterior surface of the file folder 23 has the various permanent indicia 6 visible through the film.
  • the film has been provided with a recessed surface finish 18 which is typical of a matte finish.
  • the matte finish allows written indicia 32 to be retained on the exterior of the reinforcing film 12. These indicia if written with a pencil, ballpoint pen or Sharpie TM permanent marker demonstrate excellent durability during normal use of a file folder.
  • the matte finish 18 provides recesses in the surface finish which serves to retain the ink or lead rendering these indicia less prone to smudging or accidental removal during normal use of the file. This information can be conveniently removed using a typical gum eraser 34.
  • the matte finish 18 is also present on the labeling tab 24. Other writing tools can also be tested and used if appropriate. Pressure sensitive adhesive labels generally shown as 36 can be secured by the user or by the manufacturer according to the specific requirements of a user.
  • the matte finish 18 provides strong adhesion of the pressure adhesive labels to the file folder. This is particularly desirable as these labels must continue to adhere to the file folder during the normal use and life of the file folder. Furthermore, it has been found that these pressure sensitive labels 36 can be removed by the user by peeling of the labels from the matte finish 18. It is believed the recessed surface of the reinforcing film provides excellent adhesion while still allowing manual removal of the labels if desired. The film also acts as an excellent receptor surface for labels having a cold liquid glue adhesive. Strong adhesion is achieved while still allowing manual removal of the labels. Other adhesives may also be suitable.
  • a cellulose based film and appropriate adhesive allows for moisture exchange through the film similar to the paper stock. This provides advantages with respect to adhesion and retention of labels. Furthermore, the cellulous based film folds or creases in a manner similar to paper stock. The tendency of the film to return from a folded to a flat condition is reduced.
  • the file folder can be reconditioned or reused for a subsequent application. It has been found that some industries, such as the medical or insurance industries, reuse file folders by removing the prior contents of the file folders. Under these circumstances, it is desirable to remove all existing labels such as labels 36 applied to the labeling tab and to remove any printed indicia 32 from the surface of the reinforcing film.
  • the file folder as previously described allows this to occur easily and allows new labels to be applied to the labeling tab 24. This avoids labeling over previous labels which can cause difficulties as the adhesive properties will have changed.
  • labels 36 will have a different surface finish than the surface finish 18. Removal of the labels avoids any issues with respect to poor adhesion due to changing characteristics of the original adhesive labels.
  • the reinforcing film can be used for top tab folders and side tab folders.
  • Some industries use a file folder having both top and side tabs and the film is applied about both tabs.
  • Film applied to both inside and outside surfaces of the file folder are suitable for certain high demand or wear applications. With the reinforcing film applied to both interior and exterior surfaces, the file folders are easily cleaned.
  • These file folders have particular application for demanding environments such as project management field files.
  • the oil industry requires a durable file to withstand use by several users in a relatively "dirty" environment. Oil, grease and dirt are more easily removed from the exterior of the film. Laminating on both the inside and outside of the file folder increases durability and provides improved properties with respect to demanding applications.
  • the reinforcing film substrate 12 is preferable translucent to allow the indicia 6 to be visible through the substrate.
  • This type of arrangement is particularly useful for large volume users where it is practical to have custom manufacture of the file folders. For many applications it would be desirable to have such a customized file folder for users where the volume is considerably less. Under these circumstances, the indicia 6 are not printed on the paper substrate 2.
  • the file folders will be produced without the printed indicia 6 and thus a blank reinforced file folder will result..
  • This blank reinforced file folder can be produced with the same economies of scale as a custom file folder in that large runs can be used.
  • the finished file folder is processed through a thermal printer, a printer using an ultraviolet curable ink or other suitable printer to apply similar indicia 6 directly on the surface of the reinforcing substrate.
  • a curable permanent ink such as a curable UV ink, can be used and as such, the finished reinforced file folders can be customized with the new indicia permanently secured to the reinforcing film substrate. This procedure can also be used for large volume applications.
  • a printing arrangement can be programmed to provide the desired indicia on the exterior face of the reinforced file folders.
  • the printing step can be postponed until the customized order is received.
  • the file folder is suitable for repeated use or has extended life and durability.
  • the sectional view of Figure 8 shows a paper substrate 2 which has a reinforcing film 12 applied to both the inside and the outside of the paper substrate 2.
  • the reinforcing films 12 are applied to both surfaces such that the inside and outside of the file folder is reinforced.
  • the paper substrate 2 can be made of a desirable paper stock and reinforced with the films 12.
  • a paper stock 14 reinforced with the films 12 provides excellent durability and a life similar to a much heavier paper stock file folder.
  • a file folder made of paper stock 16 has excellent durability, however, the cost of the paper stock is relatively high. Similar life can be provided merely using a thinner paper stock such as paper stock 14 and applying the reinforced film to at least one surface or on both surfaces of the paper stock.
  • a file folder has similar properties with respect to durability and expected life, while providing other desirable characteristics with respect to convenient removal of client specific information and can be produced at a similar or lower cost.
  • the breathable cellulose based film allows application of the film to opposite sides of the substrate.
  • the film provides extended folder life expectancy or similar life expectancy but using a lighter paper stock.
  • Most file folders have a paper stock thickness of 0,25 to 0,41 mm (10 to 16 thousandths of an inch).
  • a particularly desirable reinforcing film is made of cellulose acetate and is available in different thicknesses, usually less than 15,2 ⁇ (0,6 mils).
  • This film in combination with the paper substrate provides a file folder having good durability as well as the desirable features previously desired.
  • This film is recyclable in a manner similar to paper stock.
  • the matte upper surface finish is preferred to allow manual writing thereon and good adhesion with printable inks.
  • the cellulose based film is easily coloured to consistent standards.
  • the manufacture of the folder can easily and quickly change over from one colour file folder to a different coloured file folder by changing the colour of the reinforcing film.
  • the paper stock remains unchanged and can be bought in large quantities. With coloured reinforcing film, printing occurs on top of the film. This colour coding of file folders produces folders which are less prone to colour fade and have increased colour durability.
  • the cellulose based film reinforced file folder can advantageously be used with composite layered labels where the upper layer of the labels is a cellulous based film.
  • recycling of the file folder is simplified as all components are of a cellulose based material or of a material easily recycled during recycling of a paper substrate material.
  • the reinforced file folder having a cellulous based film has been described with respect to covering a majority of the front and back panels with the cellulous based film. It is also beneficial to use this cellulose based film having a matte finish on a labeling tab as superior labeling surface. Such a product provides the required durability and label retention properties with rendering the file folder more suitable for high quality recycling.
  • the file folder with the recyclable film allows erasing of pen, marker or pencil markings, is water resistance, reduces paper cuts, is dirt resistance and is easily cleaned to improve hygiene.
  • Curable ink is not removable with an eraser and as such can be used for more permanent identification. Printing on the acetate reinforcing film using an ultra violet curable ink provides permanent marking and great clarity. This ink also cures quickly allowing fast production rates.
