Description

INDEX TAG LABEL INSERT LEAVES FIELD OF INVENTION The present invention relates to multi-layer label assemblies, and more particularly, insert sheets of index tab labels that include tongue label inserts which can be printed with identification signs and inserted into transparent tabs of an index divider to assist users in identifying the divisor.

BACKGROUND OF THE INVENTION The sheets of an index divider with transparent index tabs are articles that are used, for example, by school children, businessmen, and workers in an office. Users have used index divider sheets to divide notebooks according to the study agendas, the reports according to the chapters and the presentations according to the sections that can be easily identified and accessed. With regard to the removable multi-layer label assemblies that have been used, the Patent US No. 4,910,058 issued to J Ameson et al. Discloses a form with multiple numbers of layers and with labels. The multi-layered shape of Jameson includes first and second carrier tissues secured to themselves by adhesives that can be relocated. To use the form of multiple numbers of layers with adhered labels, the form is first placed in a printer in such a way that the necessary indications can be pre-printed on each of the labels. When removed from the printer, the first fabric bearer of the shape can be removed from the second fabric, exposing the relocation-capable adhesive on the underside of the mold-cutting portions of the second fabric. The peel-off label can then be secured to a new surface using the adhesive capable of relocation. The multi-layered shape of Jameson has three layers: (1) the first carrier fabric, (2) the second carrier fabric and (3) a label layer. The number of layers in a form or sheet of multiple numbers of layers that directly affects their manufacturing cost. A form of multiple numbers of layers requires greater efforts to assemble and manufacture since it has larger components and therefore has a higher cost. U.S. Patent No. 5,135,261, issued to Cusack et al. (Hereinafter Cusack), discloses an index tab assembly that uses a label having a layer or bath that facilitates printing on the label. The assembly of the Cusack label has only two layers: (1) a backing sheet and (2) a layer of detachable labels. Each label is made of a polyester film that has a layer or bath applied to the front side of the sheet to facilitate printing when using laser or xerographic equipment and a pressure sensitive adhesive adhered to the dorsal side of the film. The labels can be attached detachably to a backing sheet. When this is configured, the labels can be fed through a laser or other printing equipment so that the indications such as numbers, letters, designs, can be printed on the labels. After the indications are printed on the labels, the particular label can then be detached from the backing sheet by reason of the cover or release layer. The label can then be adhered to a tongue enhancer using the pressure sensitive adhesive that is applied to the back of the label. The tongue reinforcement is then adhered to a tongue of the divider leaf. It is noted that when the user assembles and uses the Cusack index tab label assembly as revealed, the divider can only be identified from one side since the identification indications on the label can only be read from one side . In addition, the Cusack tab label has a pressure sensitive adhesive on it, making it more difficult to reuse the divider.

BRIEF SUMMARY OF THE INVENTION The present invention pertains to the construction and use of a new and improved assembly of multilayer labels and, in particular, to the construction and use of an insert sheet of an index tab label that (1) has a reasonable manufacturing cost, (2) has a dry take-off characteristic, (3) can be passed through a printer or a copier multiple times and (4) have tab labels that can be folded which can be read and identified by both sides. According to an exemplary expression of the present invention, an insert sheet of an index tab label, includes among other elements (1) a front reservation sheet having a plurality of tab labels that can be bent, ( 2) a backing sheet, preferably with a bath or layer for peeling, generally coextensive with the front reserve sheet, (3) a layer of adhesive, preferably a layer of pressure sensitive adhesive, between the sheet front reserve and the backing sheet treated with a layer for removal or removal and (4) a layer or bath of textured varnish under the index tab labels, which makes the inserts easily removed from the backing sheet treated with a layer or bath of takeoff. The present invention increases the effectiveness in manufacturing costs by having only two sheets: (1) a front reserve sheet and (2) a backing sheet treated with a layer or bath for takeoff. Having only two sheets, the current novel label insert sheet assembly uses a minimum number of components and therefore requires less effort in its assembly. Therefore, production costs can be kept to a minimum. Another unique feature of the present tab label insert sheet is its dry-peel feature. A layer or bath of a pressure sensitive adhesive is applied to a lower side of the front reserve sheet to secure the front reserve sheet to the backing sheet treated for peeling. A layer of textured varnish is applied to the underside of the detachable tab label inserts of the front reserve sheet. The textured varnish layer or bath facilitates easy peeling of the tab label inserts from the treated backing sheet for peeling off by cushioning or attenuating the stickiness of the adhesive. In addition, the varnish layer or bath sufficiently reduces the stickiness of the tab label inserts so that the removed inserts do not stick to the users' fingers and thus avoid inconveniencing users. Another advantage of the current novel sheet of tab label inserts is its ability to multi-step or repeat. First, the reduced wrap design of the insert sheet allows the ability of multiple steps or repetitions. The run or purge of the adhesive is a condition where the adhesive on a regular multilayer sheet is transferred from the sheet to the internal parts of a printer or a photocopier. The transfer effect is caused by the pressure and heat generated by the printer or photocopier as the usual multilayer sheet travels through the printer or photocopier. The current and novel tab label insert sheet has a tight or shut-off design where only enough adhesive, but not too much, is applied to the sheet to secure the label inserts. Thus, the design of tight or reduced shutdown reduces the risk of running or purging of the adhesive commonly found with other products of self-adhesive labels and means that even with repeated exposures to heat and pressure of the rollers of the photocopier or the printer the corrido or purge of the adhesive will not occur. Second, the inventive sheet of tab label insert is sufficiently flexible and elastic so that it can be passed through a printer or a photocopier several times. As a result, users can initially pass the insert inventor sheet through the printer to print indications on a few label inserts and can pass the sheet through the printer a second and third time to print indications on the other label inserts without having to discard the unused portion, thus avoiding waste. The foregoing and many other features and advantages of the present invention will become more apparent as the invention is better understood by reference to the following detailed description when considered in conjunction with the accompanying drawings.

BRIEF DESCRIPTION OF THE DIVERSE VIEWS OF THE DRAWINGS Figure 1 is a perspective view of an exemplary index of a tab label sheet according to the present invention. Figure 2 is illustrates a cross sectional view of the index of the tab label sheet taken along lines 2-2 of Figure 1. Figure 3 is a top and partial view of the tab label insert of the present invention inserted in the transparent tab index of an index divider.

DETAILED DESCRIPTION OF THE PREFERRED EXPRESSIONS The present invention relates to the construction and use of a new and improved assembly of a multilayer label, and in particular, to the construction and use of an index tab label insert (1) which is reasonable in its manufacturing cost, (2) which is of the relatively non-inheritance type, (3) which can be passed through multiple times by a printer or a photocopier, and (4) which has tongue tab inserts that can be folded. The following detailed description is provided to enable any person skilled in the art to make use of the invention and to elaborate on the best modes contemplated by the inventor to carry out the invention. This description should not be taken in a limiting sense, since it is done merely for the purposes of illustrating the general principles of the invention. As illustrated in Figure 1, the index tab label inserts 20 are provided in rows extending transversely over an exemplary sheet of an index tab label insert 10. The exemplary insert sheet 10 in Figure 1 illustrates fifteen index inserts. index tab label 20 in fifteen rows extending transversely, each row comprising a tab label insert 20. In practice, an insert sheet may include at least ten of labels 20. Figure 1 shows a number of rows empty 36 where corresponding tab label inserts have been removed. There is a mold cut contour 34 around the configuration of each tab label insert 20 to facilitate removal of the insert 20 from the insert sheet 10. Each tab label insert has a centric bending line 22. The line Center fold 22 divides each tab label insert 20 into a printable left half 28 and a printable right half 30. A tab insert 20 is shown with identical indicia 32 printed on both printable halves 28,30. The center fold line 22 is also a weakness line designed to facilitate the folding of each tongue tab insert 20 in halves. The line of weakness can be devised by means of perforations or by cutting by mold printing in part the front reserve, or in any other desired manner. Figure 3 shows a folded tab label insert 20 with the desired indications 32 inserted in the transparent tab 62 of the index divider 60. The insertion is made in such a way that the sides of the tab label inserts 20 carrying the indications printed look out. To use multi-layered index tab label inserts 10, the user initially sends the sheet 10 through a printer or copier to print the desired indications on one or more tab label inserts 20 on the sheet 10. A user can print identical indicia 32 on each half 28, 30 of a tab label insert 20. The user can then remove the label insert from the printed tab 20 from the tab label insert sheet 10 to along the contours of the mold cut 34, bend the insert 20 along its center fold line 22 and place the bent insert 20 within the transparent tab 62 of an index divider 60 with the sides containing the printed indications that look outward, as shown in Figure 3. When the user prints identical indicia on each printable half 28, 30 of a tongue tab label 20 and places the printed label insert 20 within the transparent tab 62 of the index divider 60. as described above, the index divider can be identified by looking either side of the transparent tab of the divider 62. The user can send the current and novel tab label insert 10 multiple times through a printer or a photocopier. First, the tight-fitting design of the insert blade 10 allows the ability of multiple steps or repetitions. The purge or run of the adhesive is a condition wherein the adhesive on a usual multilayer sheet is transferred from the sheet to the internal parts of a printer or a photocopier. The transfer effect is caused by the pressure and heat generated by the printer or photocopier as the usual multilayer sheet travels through the printer or photocopier. The current and novel sheet of tab labels 10 has a weakened or light sticking or weak design where only enough, but not too much, of the adhesive is applied to sheet 10 to secure the label 20 inserts. , the weakened or slightly glued or tight design reduces the risk of run-off or adhesive bleeding commonly found in other self-adhesive label products. Second, the tongue tab insert sheet 10 is flexible and resilient enough so that it can be passed through the printer or the photocopier multiple times. As a result, the user can print and use some of the label inserts 20 at an opportunity and economically save the unused portion of the label insert sheet 10 for use at another time. Figure 2 illustrates a cross sectional view of an exemplary sheet of an index tab label insert 10. The front reserve sheet 42 is the top layer of the insert sheet 10. A layer or adhesive bath sensitive to the pressure 46 is applied to the underlying surface of the front reserve sheet 42. The layer or bath of pressure sensitive adhesive 46 secures the front reserve sheet 42 to the backing sheet treated for peeling. A lacquer layer with design 50 is applied below each tongue tag index 20 between the layer or bath of pressure sensitive adhesive 46 and the backing sheet treated for peel 48. In practice it can be applied in a textured manner to the backup sheet 48 in the areas where the labels are located. An exemplary sheet of tongue tag insert 10 has a preferred thickness of about 8 to 12, 5 thousand metrics with the front reserve sheet 42 being about 5 to 8 millimeters in thickness, the backing sheet treated for peeling 48 being approximately 2 to 3 millimeters in thickness, and the layer or bath of pressure sensitive adhesive 46 and the layer of varnish with design 50 together being approximately between 1 and 1.5 millimeters in thickness. More generally, the tab index sheets 1 0 could be from the approximate 8 to the approximate 12 0 1 5 millimeters in thickness, so as to reliably feed through the printing machines or copiers. It is further noted that the front reservation sheet 42 is normally substantially substantially thicker than the backing sheet 48, which may be 2 or 3 times as thick as the backing sheet. The coating or bath of varnish with design 50 attenuates or reduces the stickiness of the adhesive. Thus, a user can easily remove a tongue tag insert 20 from the backing sheet treated for peeling 48 along the mold cutting contours 34 encompassing the configuration of the label insert 20. In addition the mold cutting contours 34 penetrate far enough from the front reserve sheet 42 and the layer or bath of pressure sensitive adhesive 46 such that when the tab label insert 20 is removed, the pressure sensitive adhesive and the varnish under the label insert 20 remain with the insert 20. The coating or varnish bath 50 prevents the removed tab label insert 20 from sticking to the user's fingers and thus it prevents the user from being disturbed. Also, when the user bends the tab label insert 20 into halves, the varnish layer 50 also prevents the halves from sticking to each other in the event that an initial mismatch is made. In the preferred expression, the front reservation sheet 42 used is a Pinehurst 80 # from the Cham pion firm available from Rollsource located at 2392 South Wolf Road, Des Plaines, Illinois 60018, USA. U U welcome. The indication "#" is a term in the art that represents the weight of a particular type of paper measured in a standard mode in pounds. For example, "80 #" means that the 500 sheets of a Pinehurst 80 # front reserve from the Champion firm, which has dimensions of 25 inches by 38 inches per blade, would weigh 80 pounds. This 80 pound paper is about 5.8 to 6, 1 millimeters thick. The backing sheet is of a Super Flattened Sheet 42 # available from the Avery Engineering Coating Division and is approximately 2.5 mm thick. The address of Avery Engineering Coating Division is 7070 Spinach Drive, Mentor, Ohio 44060, USA. U U welcome. The preferred adhesive is a P-39 available from Avery Central Products Division, and the preferred varnish is a gloss layer available from Sun Chemical, formula number RCA01291. Avery Central Products Division's address is 4350 Avery Drive, P.O. Box 547, Flowery Branch, Georgia 30542, USA U U welcome. Sun Chemical's address is 795 Beahan Rose, Rochester, New York 14621, USA. U U welcome. It should be noted that the front reservation sheet described above, the backing sheet, the adhesive and the varnish are used in the preferred expression. However, other types of front reserve, sheet backing, as well as other adhesives and varnishes can be employed. Although the present invention has been described in terms of the above preferred expression, numerous modifications and / or addition to the preferred expression described above could clearly be apparent to those skilled in the art. Thus, as an example and not limitation, each row of a tab label insert may be composed of more than one label insert 20. Likewise, the preferred expression in Figure 1 having fifteen tab label inserts 20. However, an alternate expression of the current tab label sheet 10 may contain at least ten inserts 20. Furthermore, in this exemplary expression, the tab label insert sheet 10, is 8 times 12. millimeters in thickness with the front reserve sheet being approximately 5 to 8 millimeters in thickness, the backing sheet treated for peeling 48 being approximately 2 to 3 millimeters in thickness and the layer or bath of pressure sensitive adhesive 46 and the layer or bath of varnish with design 50 joints being approximately 1 to 1, 5 millimeters in thickness. However, a backing sheet treated for peeling 48 that is thicker or a reserve sheet 42 also thicker, or a bath or layer of pressure sensitive adhesive 46 that is thicker, or a layer or coating bath with 50 thicker design can also be used. Also, the backing sheet 48 does not need to be provided with the usual silicone bath or release layer, since the varnish in the insert areas of the label could still allow the removal of the label 20 inserts. of the backing sheet treated for takeoff and together with a rather aggressive adhesive is preferred. It is further noted that other types of dry-take-off materials, such as paint, for specific examples, could be used instead of the varnish to provide initial adhesion., but without having stickiness after taking off the inserts of the labels. Accordingly, the present invention is not limited to specific expressions herein illustrated and described above.
