Abstract:
An extended content label with a narrow overlaminate having a substrate, a leaflet and an overlaminate strip. The leaflet is adhered to a section of the upper surface of the substrate and has several overlying panels, longitudinally-extended accordion-type folds alternating along a top and bottom of each panel, and a perpendicular fold oriented normal to the longitudinal direction. The leaflet is a single sheet that is folded into a leaflet without the use of glue. The overlaminate strip is laminated across the entire longitudinal direction of the leaflet and laminated to another section of the upper surface of said substrate to form an extended content label. The height of the overlaminate strip is narrower than the leaflet so that all of the accordion-type folds extend beyond the overlaminate strip.

Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The invention relates to an extended content label (ECL) with a narrow overlaminate. 
     2. The Prior Art 
     Frequently product containers are identified by applying an adhesive-backed label to an outer surface of the container. Such labels retain their product-identifying purpose by remaining permanently affixed to the container. 
     Certain products which require extensive instructions or which are subject to significant government regulations require additional printed matter which is typically inserted into the product container. In the case of pharmaceuticals, the printed matter may be in the form of printed sheets, printed inserts, or printed outserts. An example of such may be seen in U.S. Pat. No. 5,685,530. While these various forms of printed matter have the benefit of providing a relatively large amount of information, their overall effectiveness is limited if they become separated from the product container. 
     U.S. Pat. No. 5,830,550 entitled Booklets and Self Adhesive Labels Including the Same shows single labels and multi-up booklets adhered to a continuous web. A label product including a release liner having an upper surface and a booklet disposed on the upper surface of the release liner. The booklet includes an outer piece including a top panel and a bottom panel joined by an outer fold, an inner piece disposed between the top and bottom panels having a pair of interior panels joined by an inner fold, attaching means coupling the outer and inner pieces to one another at the outer and inner folds, and a tear line formed in the bottom panel adjacent the outer fold. A layer of adhesive is interposed between the bottom panel and the upper surface of the release liner. In certain embodiments a booklet is formed where the pages are attached together at the spine. Such booklets do not utilize accordion folded leaflets which can be made with fewer steps by eliminating internal gluing steps and external fold trimming steps. In addition, all embodiments employ a full height overlaminate which covers the entire booklet. 
     U.S. Pat. No. 6,576,315 entitled Multi-Ply Resealable Label shows booklets with windows adhered to a continuous web. A label includes a base label having upper and lower opposed surfaces and first and second opposed ends. A base adhesive coats the lower surface of the base label. A top panel overlies the upper surface of the base label and is joined to the base label adjacent the first end. The top panel has an upper surface. A tab having upper and lower opposed surfaces overlies the upper surface of the base label. An adhesive patch is interposed between the base label and the tab adjacent the second end. The adhesive patch secures the lower surface of the tab to the upper surface of the base label. A laminate cover overlies the top panel and the tab. A laminate adhesive secures the laminate cover to the upper surface of the top panel and releasably joins the laminate cover to the upper surface of the tab. 
     U.S. Pat. No. 6,432,500 entitled Label with Booklet shows a label with an overlaminate that extends beyond the label perimeter. A label with booklet comprises a liner material and a label having an upper and lower surface located on the liner. The label is secured to the liner by an adhesive layer on its lower surface such that the label can be peeled off the liner with the adhesive remaining on the lower surface of the label. A booklet is affixed to the upper surface of the label and comprises a plurality of stacked pages having edges including a top page and a bottom page, each of the pages being coextensive with each other and of smaller dimensions than the label. The booklet further comprises a cover member entirely covering the top page and extending beyond at least two opposing edges of the top page, the cover member having an upper non-adhesive surface, and a lower surface having an adhesive thereon by means of which the lower surface of the cover member is permanently adhered to the upper surface of the top page. The booklet is completely removable from the label by removing at least a portion of the cover member. 
     U.S. Pat. No. 6,432,499 entitled Nested Label shows a label with die cut windows applied to a release liner. A nested label includes a liner having a surface release, and a label removably bonded to the liner by an adhesive. The liner and label have respective die cuts spaced apart from each other at a skip in the liner release for obtaining different bond strengths between the label and liner on opposite sides of the label die cut. 
     U.S. Pat. No. 6,948,743 entitled Multilayer Label and Method of Making Same shows multi-page labels with staggered sheets to facilitate application to curved containers. A multiple layer label and a method of making the same are provided. Specifically, a label having a base layer for adhering to a container is provided wherein the label has an overcoat layer having an end that is removably adhered to the container. Moreover, the end that is removably adhered to the container is grasped by a user of the label and pulled, thereby removing the end of the overcoat layer from the container and swinging the layer away from the remainder of the label and exposing sublayers beneath the overcoat layer. The overcoat layer is adhered directly to the base layer, and at least portions of the sublayers. Each of the overcoat layer, sublayers, and the base layer may have indicia printed thereon for communicating information. 
     U.S. Pat. No. 6,179,335 entitled Product Label Bearing an Instructional Booklet shows a folded booklet adhered to a portion of a label. A two part identifying and instructional booklet having a label part and a booklet part. The front of the label has a small unvarnished region. The booklet is folded and glued closed with the free edges secured interiorly. An adhesive is printed onto the unvarnished region of the label and the folded booklet is adhered to the unvarnished region. The booklet has a tab portion to facilitate opening of the book during use. The tab portion faces the identifying portion of the label which extends longitudinally outwardly from the unvarnished region. The label may be placed onto a cylindrical container and bent in the longitudinal direction whereby the spine and folds of the booklet remain straight, flat and parallel to each other. 
     U.S. Pat. No. 6,439,614 entitled Nested Leaflet Label Structure shows a booklet adhered to a label. A nested leaflet label structure having an enhanced information carrying capacity. The nested leaflet label structure includes a base panel having a front face. A first leaflet is adjacent to the front face and comprises a first folded panel having a first fold extending substantially parallel to the first axis of the label structure. The first fold divides the first folded panel into a pair of first leaves each having inner and outer page faces. A second leaflet comprises a second folded panel having a second fold extending substantially parallel to the first axis of the label structure. The second fold divides the second folded panel into a pair of second leaves each having inner and outer page faces. A laminating layer overlies the base panel and the first leaflet. The second leaflet is nested in the first leaflet. An assembling adhesive adheres the second leaflet to the first leaflet. 
     Fold-out labels made from single sheets are shown in U.S. Pat. No. Re. 34,366 and U.S. Pat. No. 5,830,550. An example of a booklet which incorporates certain advantages of a label is disclosed in U.S. Pat. No. 5,324,559. The patent discloses a relatively simple booklet containing four sheets, i.e., eight pages. In all of these patents, the first page contains information which would otherwise be placed on the product label. The entire back page is adhered to the container leaving only the intermediate pages for instructional information. A further drawback of these patents lies in the fact that if their first page becomes detached from the booklet the product container would be unlabeled. U.S. Pat. No. 6,712,398 shows method for making removable inserts. U.S. Pat. No. 6,737,137 describes a method for manufacturing adhesive image transfer labels. 
     Accordingly, it would be desirable to provide an identifying and instructional document which combines the permanent nature of an adhesive label with the instructional capacity of a multi-page booklet. 
     SUMMARY OF THE INVENTION 
     It is therefore an object of the present invention to provide an Extended Content Label (ECL) with a large printing area that can be economically manufactured. 
     It is another object to provide an overlaminate which is narrower than the leaflet. 
     It is a further object to have leaflet folds that are free to conform to varying container radius. 
     These an other related objects according to the invention are achieved by an extended content label with a narrow overlaminate having a leaflet stacked between a substrate and an overlaminate. The substrate has an upper surface and a leaflet adhered to a section of said upper surface. The leaflet includes a plurality of overlying panels, longitudinally-extended accordion-type folds alternating along a top side and a bottom side of each panel, and a perpendicular fold oriented normal to the longitudinal direction. An overlaminate strip that is laminated across the entire longitudinal direction of the leaflet and laminated to another section of the upper surface of said substrate to form an extended content label, wherein the height of said overlaminate strip is narrower than the leaflet so that all of the accordion-type folds extend beyond the overlaminate strip. 
     The said leaflet consists of a single printed sheet that is devoid of glue in its interior. The perpendicular fold divides said leaflet into a rear portion which is disposed adjacent said label, and a front portion which is disposed adjacent said overlaminate strip. A first outer panel section of the rear portion is at least partially adhered to said facestock. A portion of one accordion-type fold adjacent said first outer panel section of the rear portion is constrained by adhesive whereby the remaining accordion-type folds are free to independently conform to various radii. A second outer panel section of the front portion is partially covered by said overlaminate strip. 
     An end panel of said overlying panels includes said first outer panel section and said second outer panel section. The overlaminate strip includes two positions: a closed position in which the leaflet is pressed flat against said label, and an open position in which the leaflet is unfolded along said perpendicular fold. The overlaminate strip pivots between said closed position and said open position along a hinge located adjacent and parallel to said perpendicular fold. 
     The leaflet includes free ends opposite said perpendicular fold, wherein in said closed position said overlaminate strip extends beyond said free ends to a location co-planar with an and of said label. In the open position the overlying panels are generally straight and flat allowing said leaflet to unfold and fold along said accordion-type folds. The leaflet includes at least one additional fold to further divide the leaflet into at least one interior portion that is disposed in between said rear portion and said front portion. 
     Alternatively, the overlaminate strip includes two positions: a closed position in which the leaflet is pressed flat against said label, and an open position in which the leaflet is unfolded along said perpendicular fold. The overlaminate strip pivots between said closed position and said open position along a hinge located adjacent and parallel to said perpendicular fold. In the open position said rear portion and said front portion are angularly spaced from each other allowing at least one interior portion to unfold so that the overlying panels are generally straight and flat allowing said leaflet to unfold and fold along said accordion-type folds. 
     The substrate comprises a facestock having a bottom surface coated with adhesive, and a release liner, where the adhesive temporarily secures the facestock to the release liner. The substrate includes a first edge and a second edge, wherein the perpendicular fold is disposed parallel to and spaced from the first edge. The said leaflet includes free ends opposite the perpendicular fold that are disposed parallel to and co-linear with the second edge of the substrate. 
     The ECL Label further includes a crush zone including of the longitudinally extending accordion type folds and at least about 5% of the leaflet area adjacent the longitudinally extending accordion type folds. All of said longitudinally extending accordion type folds within the crush zone remain free from being adhered to the substrate and the overlaminate strip. Each of said longitudinally extending accordion type folds within said crush zone has a degree of freedom for radius conformity independently of said substrate and said overlaminate. The longitudinally-extended accordion-type folds alternating along a top side and a bottom side of each panel provide an air vent for each adjacent pair of panels on the bottom side and top side respectively.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     Referring now in detail to the drawings there is shown a folded leaflet that is adhered to a substrate and partially covered by an overlaminate to form an Extended Content Label (ECL). More particularly,  FIG. 1A  shows a sheet  10  that will be folded into various forms of an accordion-folded sheet as illustrated in  FIGS. 1B ,  1 C and  1 D. One or more perpendicular folds then produces the folded leaflet  30  as shown in  FIG. 1E . The folded leaflet  30  is adhered to variously configured substrates  102  and  104  illustrated in  FIGS. 2A and 2B , respectively. These substrates bearing folded leaflets are covered by a narrow overlaminate  500  to form ECL Labels shown in  FIGS. 3A and 3B , respectively. 
     Since the overlaminate is narrower than the folded leaflet, the top and/or bottom of the perpendicular fold(s) and the corresponding top and/or bottom accordion-type folds extend beyond the overlaminate. As a result these outwardly extending folds are able to move independently of the overlaminate. Accordingly, when the ECL Label is rolled onto a cylindrical container, the free folds can be pressed flat. 
       FIG. 1A  shows a sheet  10  containing printed information  10   a . One sheet will form a single folded leaflet. Large sheets can be printed with two or more sets of information and then cut into individual sheets  10 . The sheets can be printed on one or both sides. In a preferred embodiment, the indicia includes pharmaceutical information about drugs that are packaged with the booklets. The books can be printed by any suitable industrial printing process, for example sheet offset, web offset, flexographic, rotary letterpress, or gravure. 
     Sheet  10  is accordion folded two or more times to form three or more panels.  FIG. 1B  illustrates the smallest number of folds, e.g. two accordion-type folds  16   i  and  16   ii . In this application, accordion-folded sheets are generally referred to as reference numeral  20 . The accordion folded sheet  20   a  has three panels which include panels  14   i  and  14   ii  along with outer panel  14   z . Additional panels extending from panel  14   ii  could be provided as  14   iii ,  14   iv ,  14   v  . . .  14   n . It will be appreciated that for any number of panels n the number of folds will be n−1. 
     Adding one fold and one panel to the accordion folded sheet  20   a  of  FIG. 1B  results in the accordion folded sheet  20   b  of  FIG. 1C . Starting from the back, an outer panel  14   z  is connected to panel  14   i  via accordion-type fold  16   i , next panel  14   ii  is connected via accordion-type fold  16   ii , lastly panel  14   iii  is connected via accordion-type fold  16   iii.    
     Larger sheets  10  and an increasing number of accordion-type folds could produce accordion folded sheets with a plurality of panels. For example, buckle folders having 4, 6 or more plates could be used to produce a large number of accordion folded sheets in an efficient manner. In a buckle folder, sheet  10  enters the folder until it hits the first plate and buckles. The buckling section is gripped by rollers and creased to form a first fold. The sheet continues through the machine until it encounters the second plate and buckles again. A six plate buckle folder would produce six accordion-type folds and seven panels. Buckle folders with any number of plates could produce accordion-folded sheets for use in the invention. Other types of commercial or industrial folders could also be used. 
     Before or after the buckle folder, the sheet could have perforations formed along fold line  16   iii  to enable removal of the lower panels  14   iii . Several sets of perforations could be formed at other fold lines or within the panels running parallel or perpendicular to the fold lines. As will be explained in further detail below, the outer panel  14   z  will be adhered to a substrate and an overlaminate. The lower panel  14   iii  then represents the free end, farthest from outer panel  14   z  when the leaflet is fully opened. If removable sections are to be provided, they would typically be removed from the free end, so that the other panels remain with the label and could be re-folded. 
     The leaflets are made from paper referred to as offset stock having a paper weight between 22# and 60#. The # designation is a measure of paper density measured in pounds per basis ream of 500 sheets of 17″ by 22″ paper. Such paper may be obtained from Twin Rivers Paper Company of South Portland, Me. or Finch Paper, LLC of Glen Falls, N.Y. For example Twin Rivers supplies 22# Custom Plus and 27#, 30#, 35#, 40# Pharmopaque—Regular Finish. Finch supplies 40# Finch Opaque—Wove Finish and 60# Finch Opaque—Vellum Finish. The preferred paper is Twin Rivers 27# Pharmopaque—Regular Finish. 
     Referring now to  FIG. 1D , an accordion folded sheet  20  is shown in an elevational view. While three panels are shown for the sake of clarity, the accordion folded sheet  20  represents any sheet with 3 or more panels. Accordion folded sheet  20  has accordion-type folds extending in the longitudinal direction  12   x . Perpendicular to direction  12   x  is the normal direction  12   y . Accordion folded sheet  20  has a width  12   w  that is measured in the normal direction  12   y . A perpendicular fold  26   a  is provided that runs in the normal direction  12   y . Perpendicular fold  26   a  divides the accordion folded sheet  20  into a front portion  30   f  and a rear portion  30   r . It will be appreciated that each portion contains panels  14   i ,  14   ii ,  14   iii , etc and outer panel  14   z . Front portion  30   f  and rear portion  30   r  are shown as being of approximately equal size. In other words, each portion is about one-half of the accordion folded sheets. The fold line could be shifted to produce unequal portions. In a two portion embodiment, having equal portions is preferred. 
     The front portion  30   f  is folded over the rear portion  30   r  according to the fold direction arrow  28   a , resulting in a folded leaflet  30 , as shown in  FIG. 1E . The width  30   w  remains the same as width  12   w . The length  30   x  is now one-half the length of the accordion folded sheet  20 . The outer panel  14   z  wraps around the folded leaflet  30 , with half of the outer panel residing within the rear portion  30   r  and the other half within the front portion  30   f . The folded leaflet  30  also includes a folded end  30   a  and free ends  30   b.    
     An alternate embodiment of a folded leaflet  30   c  is illustrated in  FIGS. 1F ,  1 G and  1 H. Starting with the same accordion folded sheet  20 , two perpendicular folds  26   a  and  26   b  are provided to divide the accordion folded sheet  20  into thirds. The rear portion  30   r  and front portion  30   f  are supplemented with an additional portion  30   s . The additional portion  30   s  is folded to overlie front portion  30   f  by folding in the direction of arrow  28   a  along perpendicular fold line  26   a . The resulting configuration is shown in  FIG. 1G . Next, the combined portion  30   s  and  30   f  are folded to overlie rear portion  30   f  by folding in the direction of arrow  28   b  along perpendicular fold line  26   b . A folded leaflet  30   c  is produced as shown in  FIG. 1H . The additional portion  30   s  is sandwiched between rear portion  30   r  and front portion  30   f.    
     The fold lines could be shifted to produce unequal portions. In a three portion embodiment, having equal one-third portions is preferred. An end-over-end fold as illustrated in  FIGS. 1G and 1H  can be used to produce folded leaflets having four or more panels. Alternately, a four panel sheet could be folded in half, and then half again. Other folding arrangements may be used. The key feature is that the resulting folded leaflet has a rear portion  30   r  adjacent to one side of the folded end  30   a , and a front portion  30   f  adjacent to the other side of folded end  30   a . The front and rear portion coupled to folded end  30   a  forms a hinge which allows the folded leaflet to be opened as will be discussed in greater detail below. The one or more additional portions  30   s  could be arranged in various configurations. 
     The folded leaflet  30  or  30   c  is adhered to a substrate  102  shown in  FIG. 2A . Dimensionally, the substrate  102  includes a length  102   b , a leading edge  102   c , a trailing edge  102   d  and a width  102   e . Structurally, the substrate  102  includes a text section  102   f , an adhesive section  102   g , a leaflet section  102   h , a waste panel  102   j  and a registration mark  102   k . Adhesive can be sprayed or printed onto adhesive section  102   g  to adhere a folded leaflet  30 , which will overlie the adhesive section  102   h . Note that adhesive section  102   g  comprises an area smaller than leaflet section  102   h . Leaflet section  102   h  is the exact footprint of folded leaflet. 
     Adhesive section  102   g  is 60 to 99% of the height of leaflet section  102   h . In an alternate embodiment, adhesive section  102   g  is 25 to 75% of the length of leaflet section  102   h . In a further embodiment, adhesive section  102   g  is 10 to 90% of the area of leaflet section  102   h.    
     To the left of leaflet section  102   h , there is a text section  102   f  which will remain visible after the folded leaflet is disposed onto substrate  102 . Accordingly, text, bar codes, brands or other indicia may be printed in this text section  102   f . Indicia may also be printed in the areas above and below leaflet section  102   h . Further to the left is a waste panel  102   j , bearing a registration mark  102   k . The ECL labels according to the invention may be manufactured by dispensing folded leaflets  30 , one at a time onto a continuous web of label stock which has a series of first substrates  102  along its length. In such a manufacturing process, registration mark  102   k  is read by a scanner to: print text in registration with text section  102   f ; print adhesive in registration with adhesive section  102   g ; and dispense a folded leaflet  30  in registration with leaflet section  102   h . Thereafter, waste panel  102   j  is die cut and removed from the web, leaving the release liner to carry the series of labels. Removal of waste panel  102   j  creates a small space between competed ECL Labels to facilitate peeling of individual ECL Labels without disturbing the downstream ECL Label. 
     Suitable labels include those having between 54# to 50# facestock. Such label stock is available from Avery Dennison sold under the trademame Fasson®. For example, Avery Dennison supplies 54# semi-gloss facestock (paper) coated with C2500 rubber based adhesive disposed on 40# bleached, calendered kraft stock liner; and 60# semi-gloss facestock (paper) coated with S246 general purpose permanent rubber based adhesive FDA compliant with 21 CFR 175.105 disposed on 40# bleached, calendered kraft stock liner. The preferred label stock is the latter 60# semi-gloss facestock coated with S246 disposed on 40# stock. 
     Four components are combined to form a completed Extended Content Label (ECL) label  100 . From the bottom up the four components are: (1) the substrate  102 ; (2) adhesive  400  applied within adhesive section  102   g ; (3) folded leaflet  30 ,  300 ; and (4) overlaminate  500 . 
     Glue used to secure the books to the web may be selected from various adhesives used in paper converting applications that are approved for use in pharmaceutical packaging. Such adhesive may be permanent acrylic adhesive, for example, clear, permanent acrylic adhesive S8020 available from Avery Dennison sold under the tradename Fasson®. 
     As can be seen in  FIG. 3A , overlaminate  500  includes an overlaminate tab  500   t  which extends beyond leading edge  102   c  (which is co-linear with free ends  30   b ) and folded leaflet  300 . Overlaminate tab  500   t  is temporarily adhered to the release liner in the gap between sections of facestock which has been created by removal of waste panel  102   j . Overlaminate  500  is applied as a second continuous web. A second die cut station will then cut and remove a small section of waste overlaminate  500   j  to physically separate the ECL Labels from each other. 
     Suitable laminate includes facestock between 0.8 to 1 mil thick coated with adhesive disposed on a liner. Suitable laminates are available from Avery Dennison sold under the tradename Fasson®. For example, Avery Dennison supplies 0.8 mil polypropylene facestock coated with clear, permanent acrylic adhesive; and 1 mil clear printed—treated polyester coated with S8020 clear, permanent acrylic adhesive disposed on 40# bleached white glassine liner. The preferred laminate is the latter 1 mil clear printed—treated polyester coated with S8020 clear, permanent acrylic adhesive disposed on 40# bleached white glassine liner. 
     Overlaminate  500  has an overlaminate width  500   w  that is narrower than the width  12   w  of folded leaflet  30 ,  300 . As a result a portion of folded leaflet  300  is free from overlaminate in the vicinity of the top and or bottom accordion type folds  16 . In addition, a top and/or bottom portion of folded ends  30   b  are free from overlaminate. Since the overlaminate is narrower than the folded leaflet, the top and/or bottom of the perpendicular fold(s) and the corresponding top and/or bottom accordion-type folds extend beyond the overlaminate. As a result these outwardly extending folds are able to move independently of the overlaminate. Accordingly, when the ECL Label is rolled onto a cylindrical container, the free folds can be pressed flat. 
     An alternate substrate is shown in  FIG. 2B . Dimensionally, second substrate  104  includes a length  104   b , a leading edge  104   c  and a trailing edge  104   d . The adjacent substrates are shown in partial sections as substrates  104   i  and  104   ii . In between the substrates  104  are waste panels  104   j (i) (designated in dotted lines) and  104   j (ii) bearing registration marks  104   k (i) and  104   k (ii). The registration mark  104   k  is used to align printing of indicia and adhesive onto the substrates  104 . The waste panels  104   j  are then die cut and removed from the web as part of a waste matrix that extends around the substrates. As an alternate embodiment, second substrate  104  includes leaflet section  104   h  and a leading edge extension  104   m . The leading edge extension  104   m  results in the leading edge  104   c  being spaced from leaflet section  104   h.    
     After the folded leaflet  300  is adhered to second substrate  104 , overlaminate  500  is applied to form a second ECL Label  101 . Sections of overlaminate  500  are trimmed off so that the remaining overlaminate has a length about the same as the second substrate  101 . The overlaminate tab  500   t  now adheres to leading edge extension  104   m . Overlaminate tab  500   t (i) can be removed and re-adhered to second substrate  104 , which would provide a more uniform adhesion surface than a cylindrical container made of unknown material. 
       FIG. 3C  shows a bottom plan view of the ECL Label  100  of  FIG. 3A . When substrate  102  comprises label stock, a conventional web having facestock  106  adhered with adhesive  108  to a release liner  110 . Facestock  106  has a top surface  106   a  and a bottom surface  106   b . Top surface  106   a  has various structural features as shown in  FIG. 2A . Adhesive  400  will be printed to top surface  106   a , folded leaflets  300  will be attached to the adhesive and overlaminate  500  will be applied to top surface. Bottom surface  106   b  is coated with adhesive to adhere it to release liner. Die cutting will remove sections of facestock  106  and adhesive  108  leaving release liner intact. Release liner includes an upper surface  110   a  and a lower surface  110   b.    
     In use, ECL Label  100  will be peeled off release liner  110  and release liner will be disposed of or recycled. Facestock  106  will be adhered to a cylindrical container. Overlaminate tab  500   t  will hold the folded leaflet closed with its overlaminate tab  500   t  removably adhered to the container. A closed state  500   c  of the overlaminate has overlaminate tab adhered to the container. In an open state  500   d , overlaminate is peeled away in direction  500   e  carrying front portion  30   f  with rear portion  30   r  remaining adhered to facestock  106 . 
     As mentioned earlier, overlaminate has a width  500   w  that is narrower than the leaflet width  12   w . As can been seen in  FIG. 3B , the folded leaflet  300  will possess an upper crush zone  330   c , a lower crush zone  300   d , or both. As will be appreciated, upper crush zone  300   c  includes all the upper accordion-type folds  16 . It will also include the upper portions of the perpendicular fold(s)  26 , that is portions of perpendicular fold(s)  26  that intersect the upper accordion-type folds  16 . Lower crush zone  300   d  includes all the lower accordion-type folds  16 . It will also include the lower portions of the perpendicular fold(s)  26 , that is portions of perpendicular fold(s)  26  that intersect the lower accordion-type folds  16 . When ECL Label  100  is placed onto container  700  a roller  600  moving in direction  600   a  will crush the folded leaflets to conform it to the radius of the container. The exposed folds in the crush zones  300   c  and  300   d  will be deformed and crushed as the panels fan out. By limiting adhesive section  102   g  to a minor portion of rear portion  30   r , and limiting the width of overlaminate, and omitting glue within the folded leaflet; the majority of the panels and folds are free to move independently of the substrate and overlaminate. This independent movement of panels in combination with crushing the folds provides a thinner ECL Label at any radius. 
     In addition, the accordion folds allow air to escape from within the folded leaflets as the roller presses the ECL label onto its container. As can be seen in  FIGS. 1B ,  1 C and  1 D, each accordion fold  16  forms a V shape of two adjacent panels. Air which may be entrapped between any two panels can be flushed out through the open end of the V, that is, the side opposite the accordion fold. So for an accordion fold along the top, air can escape from the bottom of the folded leaflet. Correspondingly, for an accordion fold along the bottom, air can escape from the top of the folded leaflet. As can be seen in  FIGS. 1F and 1G , this accordion fold venting can still occur if the leaflet has two or more perpendicular fold. While the perpendicular folds may limit venting in the longitudinal “X” direction, each panel section can always vent through the top or bottom, opposite the accordion fold. 
     In a practical embodiment, the label width  102   e  is 44 mm, the accordion folded sheet has a width  12   w  of 32 mm and the overlaminate width  500   w  is 26 mm. 
     Structurally, the ECL Label  100 ,  101  has an accordion folded sheet with a width  12   w  that is 60 to 90% of the label width  102   e , preferably 65 to 80% of the label width and more preferably 73% of the label width. 
     Structurally, the ECL Label  100 ,  101  has an overlaminate width  500   w  that is 70 to 90% of the accordion folded sheet width  12   w , preferably 75 to 85% of the sheet width and more preferably 81% of the sheet width. 
     Structurally, the ECL Label  100 ,  101  has an overlaminate width  500   w  that is 40 to 80% of the label width  102   e , preferably 50 to 70% of the label width and more preferably 60% of the label width. 
       FIGS. 4A and 4B  show ECL Label  100  adhered to a container  700 . Overlaminate tab  500   t  can pivot in the direction of arrow  500   f  to the closed state  500   c  to close the folded leaflet  300 . Overlaminate tab  500   t  can pivot in the direction of arrow  500   e  to the open state  500   d  to open the folded leaflet  300 . In the open state, the perpendicular folds  26  are unfolded, returning the leaflet to the flat configuration of accordion folded sheet  20 . The accordion folded sheet can unfold the accordion-type folds  16  to return to the open configuration of sheet  10 . Compared to other leaflet configurations, it is obvious and apparent how to re-fold the expanded sheet. The bottom panel is folded above or under the panel above it. This step is repeated until the sheet is one panel wide and even with the label. Additional portions can be tucked in and the overlaminate pivoted back to its closed state. 
     While various forms of leaflets have been shown and described, it should be understood that additional configurations may be provided within the scope of the application. For example, leaflets with a greater number of panels and accordion and perpendicular folds may be provided. The leaflets can be aligned to or spaced from the leading edge of the substrate. The overlaminate may align to the leading and/or trailing edge of the substrate. The overlaminate may overhang the leading and/or trailing edge of the substrate. 
     Having described preferred embodiments for leaflets, panels, folds and labels (which are intended to be illustrative and not limiting), it is noted that modifications and variations can be made by persons skilled in the art in light of the above teachings. It is therefore to be understood that changes may be made in the particular embodiments of the invention disclosed which are within the scope and spirit of the invention as outlined by the appended claims. Having thus described the invention with the details and particularity required by the patent laws, what is claimed and desired protected by Letters Patent is set forth in the appended claims.
