SEMI-PERMANENT FILING, FLAGGING AND INDEXING SYSTEM

Abstract: A flag (10) of unitary construction formed frm a sheet of flexible, semi-rigid material having a central adhesive section (20) on one side, flanked by two symmetrical adhesive free tabs (22) which are printed so as to facilitate indexing or signaling of flagged material, may be reversibly attached to host material book, file card, file folder or the like proximate a free edge with one adhesive free tab protruding from the free edge host and one tab overlying a portion of the flagged host. The flag (10) may be removed from the flagged host by grasping the adhesive free overlaying tab (22) and peeling the flag outward relative to the free edge of the host without damage to the host, or the flag may be used to flag a section of text not proximate an edge of a host by pressing down the transparent adhesive bearing central section directly over or adjacent to the portion of text to be flagged.

Description: S EMI-PE RMANENT F ILING, FLAGG ING AN D IN DEX I NG SYSTEM BACKGROUND OF THE INVENTION 1. Field of the Invention The invention relates to indexing and flagging materials and particularly to semi-permanent locator flags and indexing systems thereto pertaining. 2. Description of the Prior Art Means for the indexing, syste ization, and retrieval of information in a referenced source conven¬ tionally and at present consist of either three part pronged pieces which are slipped over a page of a book, paper clips, loose media, bookmarks, glue attached indexes, etc. The chief and universal disadvantages of the aforementioned devices lie in their inefficiency and in the damage they frequently cause to the pages and binding of a referenced source. Indexing devices which are not adhesively attached to the printed pages of a referenced source or host either fall out or off of the reference source, while those that are adhesi¬ vely attached are not readily removable without damage to the indexed page. Additionally, the protrusion-of devices attached to a page of a referenced source, especially in the case of glue attached indicia, fre¬ quently damage the pages of a reference when struck by a foreign object since they transmit that striking force to the page of the reference. Glue attached indicia are also frequently troublesome to handle since they are functional only in a very specified orien¬ tation relative to the page of the reference to be indexed, and frequently require attachment to both sides of the page. Glue attached indicia which are attached to a page of reference source proximate its bound edge, and which overlay a horizontal section of the indexed page or indeed the entire page, are troublesome to apply, unnecessarily bulk out a referenced source when used in any significant number due to their incorporation proximate the binding of the referenced source, and must frequently be treated as oages in and of themselves making them awkward to use, limiting the number of textual units which may be indexed on any given page, or indeed within the entire reference owing to their greater bulk. Some host material is subject to frequent agitation and impact where rigid indicia are unsatisfactory. Host material in some instances must traverse areas where there is not enough clearance for a rigid indicia. O^ the devices which the applicant uncovered during his research in the field of the present inven¬ tion, U.S. Patent Nos. 4,214,024; 2,109,583; and 3,312,005 disclose general purpose adhesive devices and are not related to the problems of referenced source indexing. U.S. patent No. 3,540,140 discloses a foldable label holder which depends upon the per¬ foration of an indexed sheet -and is consequently severely limited in its desirability and use. U.S. Patent Nos. 1,151,475; 1,848,098; 2,893,144; 3,001,306; 3,191,767; 4,109,759; 3,805,426 reissued as 29,422; and 3,691,662 all make reference to glue attached indexed tab devices which are adhesively attached to both sides of a printed sheet proximate a free edge. As such, they are more troublesome to apply than necessary, and gratuitously bulk out a reference source thereby indexed owing to their double thickness. Only the OMPI Stanton Patent 4,019,759 makes any reference to the removal of such tabs. This is effected in the Stanton Patent by a rotating tab which passes between the adhe¬ sive covered section of the index and the flagged page. Such a mechanism, however, requires the indexed tab be of an undesirable rigidity and bulk. Of indexing devices uncovered which are adhe¬ sively attached to only one side of a page to be indexed Patent Nos. 1,241,049 and 876,767 refer to devices which are attached to the page proximate its bound edge and which overlay a significant portion of the indexed page. Both would tend to unnecessarily bulk out and clutter any reference source thereby indexed, while Patent No. 876,767 discloses an index which is only truly useful for separating major sections of a referenced source. U.S. Patent No. 1,614,838, also discloses an index tab device which is attached to a printed sheet proximate its bound edge and addi¬ tionally requires that the device be slipped over the sheet and attached to both sides of the page. Of the devices disclosed by Patent Search, the indexing means closest to the present invention in spirit is the Rivkin U.S. Patent 2,353,042, granted to the applicant in September, 1958. The indexing means therein disclosed, however, relates specifically to the indexing of magnetic recording tape and is not referred to the problems of removing adhesively attached flags from easily damaged host media owing to the far greater strength of magnetic tape. No device or system has heretofore appeared which provides for the easy and rapid attachment of semi-oer anent flagging means on one side of a host proximate a free edge, which does not significantly bulk out a host when utilized in great numbers throughout such a host, transmits no potentially damaging striking force to the host when struck by a foreign object, and provides for easy removal of the lag means without damage to the host. For the indexing or highlighting of infor¬ mation not proximate a free edge of a host, current practice includes only the underlining of such material with pencil or pen or overlining of the material by means of a highlighting marker utilizing translucent ink. Applicant is aware of no device or systtem which provides for such indexing and highlighting by means of a semi-permanent transparent adhesively applied flag. U A Y OF THE INVENTION In view of these and other problems in the art, it is a general object of the present invention to provide a small, semi-permanent flag which may be quickly and easily attached to one side of a host proximate a free edge. It is another object of the present invention to provide a flag of the character described which may be reversibly attached to a host in either of two orientations. Another oh ect of the present invention, is to provi d e a flag of the character described having a central adhesive bearing section flanked by two adhe¬ sive free tabs, one o? which protrudes from the edge of the host, while h other overlays a portion of the host. Yet another object of the present invention, is to provide a flag of the character described wherein the adhesive free tabs are tapered so as to enhance the bendability of the flag. Still another object of the present invention, is to provide a flag of the character described wherein the taper of the adhesive free tabs protruding from the host edge together with the bendability of the flag permit the protruding adhesive free tabs to deflect under a striking force by a foreign object thereby transmitting almost none of the striking force to the host. Still another object of the present invention, is to provide a flag of the character described which may be removed from the host by grasping an adhesive free overlaying tab, and peeling the flag outward with respect to the free edge of the host, thereby avoiding any tearing or other trau atization of the host. Another object of the present invention, is to provide a flag of the character described which is thin enough so that a great number of such flags may be used to index a bound source reference without signi icantly bulking out the reference. Another object of the present invention, is to provide a flag of the character described wherein the adhesive free tabs are symmetrically printed with color and number or letter in order to facilitate the groupinq and sequencing of indexed material. Another object of the present invention, is to provide a flag of the character described having a central transparent section such that a word, number or phrase in the middle of a printed host material may be flagged by attaching the transparent area of the flag directly over the information to be indexed, and the area defined with a narrow printed line around the periphery of the flag. It is another object of the present invention to provide a flag of the character described having a central transparent area which may be written on by the user in order to facilitate the user's organization of the indexed material. A flag formed of a semi-rigid, flexible material, having a central adhesive bearing section on one side o f the flaq and two adhesive free tabs flanking the adhesive bearing section, is applied to a host material proximate a free edge of the host with one ^ the adhesive free tabs protruding from the edge of the host and one of the adhesive free tabs overlying a portion of the flagged host. The application of the flag is reversible insofar as either of the adhesive free tabs may be in the protruding or overlaying posi¬ tion, ^ adhesive free tabs are tapered in such a way as to enhance the flexibility of the flag and such that whichever adhesive free tab is protruding from the free edge of the flagged host will cam away from and deflect under a striking force from a foreign object. Removal of the flag is effected by grasping the adhesive free overlaving tab, and peeling back the flaq outwardly relative to the free edge of the host so that no poten- tiallv damaging shearing force is exerted upon the flagged host. The adhesive free tab may be printed with a color coded and/or symbolic sequencing so that the flagged material may be coordinated with other materials similarly flagged an.-Vor imprinted. The flag also has a central transparent section so that specific portions of text in the middle of a host may be high¬ lighted and indexed by simply pressing the flag down over the material to be highlighted such that the desired text is visible through the transparent section and flagged above and below by the printed adhesive free tabs, or enclosed in a line printed around the periphery of the file flag. This transparent section may also be written on by the user in order to facili¬ tate the organization of flagged material.

A central adhesive section 20 runs diagonally across what wil be referred to as the reverse side 16 of the file flag 10 and defi¬ nes a longitudinal axis of adhesion 18 and the axis of functional symmetry of the flag 10. The central adhe¬ sive section 20 of the flag 10 may utilize a pressure sensitive adhesive which allows the flag 10 to be applied to a surface, removed, and reapplied there or elsewhere. Here, as elsewhere in this description, longi- tudinality refers to a dimension collinear or parallel to the diagonal of the flag 10 bearing the central adhesive section 20. The dimension transverse to this diagonal and σoplanar with the sheet of the flag 10 will be referred to as latitudinous. The side of the flag in which bears the adhesive will be referred to as the reverse side 16 of the flag 10 while the adhesive free side is the obverse side 14.. These terms have heen used in order to facilitate and clarify the disclosure of: the present invention and it is to be understood that they have not been used by way of limitation. The central adhesive section 20 divides the remainder of the flag 10 into two tapered adhesive free tabs 22 which are symmetrical about the axis of adhe¬ sion 18. These tabs 22 are of a substantially iden¬ tical configuration and are functionally di rentiated by the orientation of the flag 10 with regard to the edge of the surface to which the flag 10 is applied. In a primary usage of the present invention, the flag 10 is applied to one side of a sheet of printed media with the axis of adhesion 18 parallel to the edge of the sheet, as indicated in FIG. 3, with one of the adhesive free tabs 22 extending freely outward from the edge of the flagged sheet. In this way, the two tapered adhesive free tabs 22 are dif erentiated into a protruding, tapered indexing tab 24 and an overlaying tapered indicating tab 26. The protruding indexing tab 24 functions as an indicia or bookmark while the overlaying tab 26 may be used to indicate a section of text on the flagged host. The symmetry of the adhesive free tabs 22 allows these tabs 22 to assume either of the functional roles of protruding tab 24 or of overlaying tab 26 rendering the flag 10 latitudinally reversible, ^his reversibility allows the flag 20 to be applied in either of two equivalent orientations requiring only that the axis of adhesion 18 be substan¬ tially parallel to the edge of the flagged host. Conseαuently, since the user need not be concerned with which of the tabs 22 protrudes from or overlays the host, the F lag 10 may be applied with great rapidity and faσilitv. ^ e adhesive free tabs 22 are sym¬ metrically tapered at preferably approximately an angle of 45 degrees relative to the axis of adhesion 18. Any qreater angle of taper would tend to compromise the camming function of the protruding tab 24, while a lesser angle would not contribute so much to the ben¬ dability of the flag 10. Since the taper of the adhe¬ sive free tabs 22 may be considered as along an axis transverse to the axis of adhesion 13, once the flag 10 is fixed into place along its axis of adhesion 18, all bendability of the flag 10 will be deflected into a plane orthogonal to that of the flagged host and to the axis of adhesion 18. FIGS. 4-6 depict the protruding indexing tab 24 being struck by a foreign object after the flag 10 has been affixed to a page of a book to be indexed. The protruding indexing tab 24 is struck along a line parallel to the axis of adhesion 18, which is poten¬ tially the most damaging to both the flag 10 and the flagged sheet since the striking force has little or no component parallel to the plane of bendability. The taper of the rotruding tab 24, however, causes the tab 24 to act as a cam allowing the protruding tab 24 to deflect under the striking force as indicated in FIG. 6 within the plane of bendability causing no damage to either the flag 10 or the flagged sheet. The rounded corner 12 of the protruding tab 24 completes and enhan¬ ces the camming action of the protruding tab 24 under a striking force more efficiently than a truncated tab and prevents the tab 24 from catching on a foreign object as might a pointed tab. The flexability of the material from which the flag 10 is formed, the taper of the protruding tab 24, and its culmination in a rounded corner 12, all act in synergistic concert with each other in order to cause the protruding tab 24 to deflect under a strikinq force rather than transmitting that striking force to the flagqed sheet, disrupting and possibly damaging that sheet. These identical features synergize again as part of the function of the overlaying tab 26 in order to prevent trau atization or damage of the flag sheet in a different manner, ^he taper of the overlaying tab 26 functions not only as an arrow to indicate a section of text, but also to facilitate removal of the flag 10 without damage to the flagged host. The transverse orientation of the taper of the overlaying tab 26 rela¬ tive to the fixed axis of adhesion 18 of the flag 10 increases bendability of the overlaying tab 26 in a latitudinal direction while the fixity of the central adhesive section 20 reduces bendability of the flag 10 in the longitudinal direction. Since the overlaying tab 26 is adhesive free, it may be readily lifted from the face of the flagged host and peeled back outwardly relative to the edge of the host levering the central adhesive section 20 of the flag 10 from the flagged host. The rounded corner 12 of the overlaying tab 26 allows the tab 26 to be caught by the thumb or the finger without jabbing the delicate flesh under the nail. Then as the tab 26 is peeled back outwardly relative to the edge of the page, a substantially verti¬ cal removal force is applied evenly over an increasing cross-section of the adhesive area 20. The cross- section of the adhesive section 20 being detached from the flagged host increases with the taper of the overlaying tab 26 until the rounded corners 12 per¬ taining to the longitudinal extremes of the adhesive section 20 smoothly lead into the diminishing cross- section of the protruding tab 24. The elimination of adhering corners further minimizes traumatization of the flagged host luring removal of the flag 10. This m thod of removal by outwardly peeling the flag 10 from the flagged host substantially eliminates any traumati¬ zation of the flagged host in terms of shearing force. Tabs which are removed from a sheet by peeling inwardly apply a shearing force to the edge of the page at the longitudinal extremes of these tabs thereby potentially tearing the flagged host. Tabs which lack the bend¬ ability necessary to transmit a substantially vertical removal force also apply a horizontal shear to the flagged host thereby potentially marring the surface of the host and destroying any information stored on that surface. T us, the enhanced flexability of the flag 10 of the present invention and its mode of outward remo¬ val minimize the potential of damaging a flagged host by substantially eliminating shear forces in two direc¬ tions which are normally exerted upon a flagged host during removal of an indexing means. On the obverse side 14 of the flag 10, the tapered adhesive free tabs 22 bear symmetrically printed flagging areas 28. These printed flagging areas 28 code the flags by means of color and symbolic sequencing, for instance, alphabetically or numeri¬ cally. These symmetrically printed areas 28 are easily comprehensible as indicated in FIG. 1, when either of the two tapered adhesive free tabs 22 protrudeε =rom a free edge of a flagged host as indicated in FIG. 3. The color coding on the printed flagging areas 28 allows groups of the flags 10 to indicate at a glance the inter-relation of various discrete sections of flagged material. The symbols included in the printed flagging areas 28 allow for the sub-categorization of sequencing of such material. Thus, when it is desirable to visibly reference material contained in a book magazine, file folders or Roladex or time cards, etc. , a number of flags 20 may each be applied to one i e of discrete pages contained in such media, so that the printed flagging areas 28 coded both by means of color and of symbol protrude beyond the page edges. Thereafter, whenever the user wishes to return to the specific information thereby flagged, he seeks the appropriate color and symbol through an index source. This system is highly adaptable for various individual applications since the flags 10 are coded by both color and number or letter or other symbolic means, when a flag 10 becomes obsolete it is readily removable without damage to the host by peeling off the flag 10 outwardly relative to the free edge of the host. The present system is especially useful when a multiplicity of users are all accessing a single source of infor- mation. When several people are working with the same reference, each may be assigned a color for iden- tification so that each has his own group of semi¬ permanent flags 10 remaining on the reference material without conflict, within that color grouping, various letters or numbers can indicate sub-categories of interest to the users. A great deal of indexing may be done in this way with any one source since each of the flags 10 is only approximately 1 1/2 mils thick and typically staggered in location throughout the source reference so that a great many of the flags 10 may be utilized without significantly bulking out a bound refere A secondary use of the present system for indexing printed material relates to mid-page flagging. When it is necessary to index a single number, word, phrase, sentence or other section of material in the middle of a reference, a flag 10 may be applied directly over such information in the middle of a page or sheet as indicated in FIG. 8. This use of the flag 10 is enabled by the lack of printing on the obverse side 14 of the flag 10 opposite the central adhesive area 10 on the reverse side 16 of the flag 10. Thus, when the central adhesive section 20 of the flag 10 is affixed directlv over information to be indexed, that information is seen through the transparent central textual flagging area 30 of the flag 10 and is high¬ lighted above and below by the symmetrically printed flagging areas 28, or a printed line defining the edge of the flag. In this manner, the importance of minute OMPI bits of information with a reference may be made imme¬ diately empirically evident. It is possible to incor¬ porate this mid-page flagging use of the present system into the use of the system first described by the manu¬ facture of flags 10 coded only by color with which mid- page material may be flagged. The free edge of the flagged page may be evidently indexed without disrupting any necessary sequencing of the numbered or lettered flags 10. The central transparent textual flagging areas 30 of the flags 10 may also be used for another form of textual flagging. hen the flags 10 are utilized proximate a free edge of a host in the manner first described a word or number which may jog the memory of the user when accessing a reference may be scripted by the user upon the transparent textual flagging area 30 of the flag 10 on its obverse side 14 and remain visible and without conflict with the sym¬ metrically printed flagging areas 28. Consequently, the user may create removable marginalia to be utilized in conjunction with host edge indexing and mid-page flagging as part of the triple-faceted systemization information allowed by the present invention. Flags may be prepared in such a way as to permit user writing in area 28 instead of imprinted with number or letters. Another basic use of the signal flags is in cooperation with an automated sorting or routing. When attached to a host which is then conveyorized, the flag 10 can either mechanically or photoelectriσally acti¬ vate routing and also counting controls. The mechani¬ cal method can be a simple miσroswitch. The photoelectrical controls can be arranged to read printed symbols, light levels as controlled by printed colors or patterning or light reflectivity. The latter can be augmented by making the flags 10 from a meta- lized semi-rigid flexible material which is imprinted to create patterns of controlled reflectivity which may be identified by a photocell or other light discrimi¬ nating technique. Since the flags 10 may be attached to a host by automated devices, high speed mail and message sorting and control may be greatly facilitated by use of the flags 10. The manufacture of the flags 10 may be accomplished efficiently and economically in a manner versatile enough to be readily effected by contemporary manufacture techniques. A web 32, preferably approxi¬ mately 1 1/2 mils in thickness, of strong flexible, tear resistant elastomeriσ material such as polyester or the like, is printed with number or letters and colors in a discrete pattern 34 such that these num¬ bers, letters or other symbols are.readable from one side of the plastic web 32. ^he other side of the web 32 is then coated with a pressure sensitive, semi¬ permanent adhesive in such a way that a linear pat¬ terning of the pressure sensitive adhesive is left crossing the printed pattern 34 of the plastic web 32 and forming what will become the central adhesive sec¬ tions 20 of the file flags 10 within the printed pat¬ tern * *4. The plastic web 32 is then mounted upon a carrier web 36 as indicated in FIG. 13 such that the pressure sensitive adhesive is between the plastic web 32 and the carrier web 36 binding them in a semi¬ permanent fashion. The combine web 38, is then pro¬ cessed preferably flexigraphically so that the printed pattern 34 on the plastic web 32 is indelibly imprinted upon the plastic web 32. The combined web 38 is then subjected to a die-cut procedure wherein only the plastic web 32 is cut through and remains attached by the pressure sensitive adhesive to the carrier web 36. Resulting from this procedure are the flags 10 of the present invention grouped and affixed to the carrier weh 36 from which they may be singly removed. The final manu acturing function is the separation of groups of these numbered, colored adhesive coated flags 10 still mounted on the carrier web 36 into small workable units resulting in small sheets of the com¬ bined web 38 each bearing typically from between 8 to 24 flags 10 apiece. There are several methods by which pressure sensitive adhesive may be applied to the surface of the plastic web 32. Pressure sensitive adhesive in a substantially fluid form, for instance, may be striped across the plastic web 32 by rollers or by brushes or other means, drying in the desired pattern. An entire side of the plastic web 32 may be coated with a pressure sensitive adhesive and then selected portions of the pressure sensitive adhesive may be rendered inactive hy deactivating the adhesive, for instance, or by loading the adhesive by means of dusting select areas of the coated plastic web 32, as with a powder, such that areas of the adhesive are permanently bound up and will no longer adhere to other surfaces. A third method is to apply double coated strips of adhesive tape to the plastic carrier web 2 where the strength of adhesion of the tape is biased towards one side. In this manner the tape may be permanently attached to the plastic web 32 while being only semi-permanently attachable to other surfaces through use of two dif¬ ferent adhesives. FIGS. 9-12 depict various patternings of the pressure sensitive adhesive on the surface of the plastic web 32. As shown in FIG. 9, the pressure sen¬ sitive adhesive may be patterned in a number of thin parallel adhesive stripes 40, separated by adhesive free interstices 42. These multiple stripes 40 form the anchoring means of the flags 10 to a page or a sheet of material to be indexed providing high longitu¬ dinal adhesive coverage but far less intense latitudi¬ nal coveraqe. Since the flags 10 are removed laterally with respect to the host, these thin multiple stripes 40 will readily release the host as the flag 10 is oeeled back, while otherwise holding the flag 10 firmly in place. he pressure sensitive adhesive may also be applied in single, broad adhesive stripes 44, or in a ^ot pattern 46, or in an adhesive cross hatching 48 as illustrated in FIGS. 10-12 or other patterns balancing percent of coverage against adhesive characteristics. In sum, the system of the present invention allows for the effective systemization and retrieval of indexed material from a source reference. The con¬ figuration of the flags 10 allow for rapid indexing of a printed media, provide for deflection of the protruding tapered indexing tabs 24 under a striking force rather than disrupting and possibly damaging the indexed material, and for ready removal of the flag 10 without any likelihood of damaging the flagged host. The taper of the adhesive free tabs 22 enhances the deflection of the protruding tapered indexing tab 24 under a striking force and also enables the ready remo¬ val of the flag 10 by the peeling back of the overlaying tapered adhesive free indicating tabs 26 outwardly relative to a host' s edge. The particular taper of the adhesive free tabs 22 has experimentally been found to effectively enhance the camming function and bendability of the adhesive free tabs 22. The pre¬ sent invention also allows for the mid-page flagging of information within a printed host in a manner which has hitherto been unknown. While the present invention has been described with reference to presently preferrerd embodiments, it is to be understood that alterations may be made by a person skilled in the art without departing from the scope and spirit of the invention as set forth in the appended claims.
