TECHNICAL FIELD
The present invention relates to hard cover products. More particularly, the present invention relates to an intermediate liner with a concealed security device for facilitating manufacture and use of hard cover products.
BACKGROUND OF THE INVENTION
In recent years, tracking of inventory of goods has become of increased importance. Inventory of goods represents a significant investment in capital. In addition to cost factors, other aspects prompting increased interest in tracking inventoryinclude the increase in just-in-time manufacturing in which materials are provided by suppliers shortly prior to the time of use by the manufacturer of goods, as well as theft deterrence and inventory verification and auditing.
Various electronic and mechanical devices have been provided for tracking and monitoring of goods and containers. These devices include acoustic magnetic security strips and radio frequency security tags. These devices often are embodied intags, pods, labels, or patches, having adhesive surfaces for attaching the device to the goods or their containers. These devices facilitate tracking and monitoring of goods and containers. The security devices are typically attached to the articlesparticularly susceptible to pilferage and improper removal from a warehouse or retail store. The security devices include a detectable sensor. One known type of security tag has a circuit that resonates at a predetermined detection frequency range. Atransmitter provides electromagnetic energy that excites the circuit. A receiver detects the output signal from the resonating circuit. The transmitter and the receiver are located at detection points, often exits from retail facilities. As thearticle is carried through the detection point, the receiver signals an alert when an activated sensor device is detected. For articles that are permitted to pass (such as purchased articles), a separate device is used to deactivate the detectablesensor prior to passage. Other devices include RFID devices that communicate digital signals. In some known RFID devices, the signal is indicative of unique identifiers for tracking particular containers.
Often large retailers require manufacturers of articles to include tracking and monitoring devices within the containers for the articles. For smaller retailers and smaller inventories of articles, the tracking and monitoring devices may not beincluded with or attached to containers. In such circumstances, the articles may be provided with after-market tracking and monitoring devices. For example, electronic article surveillance tags are available with adhesive backing to secure the tags tothe containers. While the containers are thereby subject to electronic article surveillance, the adhesively attached tags experience problems during use. One significant problem is that the tags, being on the exterior of the container, are susceptibleto removal. Removing the security tag facilitates unauthorized removal of the article from the secured area. However, removal by a purchaser also causes problems. The covering to which the security tag attaches may become torn or ripped. The packagewith the security tag, or without such by removal, is unattractive. The security tag may also overlie or cover over ornamental graphics or text on the packaging.
Also, importantly, the attachment of an electronic security tag to an interim assembly of an article during manufacture lead to production and handling problems. The security tag projects from the surface to which it attaches. This causesstacked ones of the interim assemblies to gradually angle or tip as the stack height increases with placement of additional interim assemblies. For example, hard cover books assembled using casing machines receive an outer liner that attaches to frontcover stock and back cover stock. Such interim assemblies are stacked for a second pass through the casing machine to apply an inner liner. Angled stacks make production and handling more difficult during manufacturing. Further, the protrudingsecurity tag may scratch the adjacent assembly, for example, when a feeder device pushes one of the assemblies from a hopper for processing and applying the inner liner.
Accordingly there is a need in the art for providing hard cover products with concealed security tracking and monitoring devices. It is to such that the present invention is directed.
SUMMARY OF THE INVENTION
The present invention meets the need in the art by providing an intermediate cover board for hard cover products, in which a primary sheet having a first thickness and opposing planar surfaces defines a receiving cavity in a selected portion ofthe sheet. The receiving cavity receives a security device. The cover board thereafter is suitable for overlay by a cover liner during manufacture of a hard cover product.
In another aspect, the present invention provides a laminated cover board for hard cover products in which a primary sheet having a first thickness and opposing planar surfaces defines a receiving cavity in a selected portion of the sheet, whichcavity receives a security device. A pair of opposing secondary sheets each with a second thickness less than the first thickness are laminated to the opposing planar surfaces of the primary sheet. The security device is thereby enclosed between thelaminated secondary sheets of the second thickness sufficient that the assembled intermediate laminated cover board does not display surface indications of the presence of the security device.
In another aspect, the present invention provides a method of assembling an intermediate laminated board for subsequent use as a component of hard cover products, comprising the steps of:
(a) providing a primary sheet having opposing planar surfaces with a length and width exceeding a first thickness, the primary sheet defining an opening therethrough in a selected portion thererof;
(b) laminating a first exterior sheet to a first of the opposing planar surfaces and closing the opening in the primary sheet;
(c) positioning a security device in the opening, the security device having a thickness no greater than about a substantial majority of the thickness of the central sheet so that opposing sides thereof are no more than substantially co-planarwith respective ones of the opposing planar surfaces of the central sheet; and
(d) laminating a second exterior sheet to the second of the opposing planar surfaces to form an intermediate laminated board that does not display on the opposing surfaces defined by the exterior sheets indications of the presence of the securitydevice therein. The resulting laminated cover board is gainfully used as a cover board in a hard cover product having an outer cover and an inner liner while not displaying indications of the enclosed security device.
Objects, advantages and features of the present invention will become apparent from reading of the following detailed description of the invention and claims in view of the appended drawings.

DETAILED DESCRIPTION
Referring now in more detail to the drawings in which like numerals refer to like parts throughout the several views, FIG. 1 illustrates a hard cover product 10 having an outer liner 12, a pair of spaced-apart sheets 14, 16, and covered by aninner liner 18. The enclosed sheets 14, 16 define front and back covers for the product. A pair of spaced-apart grooves or scores 20 enable the sheets 14, 16 to fold together to close the hard cover product 10. A gap 22 between the scores 20 defines aspine or back of the closeable hard cover product 10. A security sensor 24 attaches with adhesive to the face of the inner liner 18 in a selected position. The sensor extends above the surface defined by the inner liner 18. As illustrated in FIG. 2,this can lead to handling and production problems during manufacture of the hard cover product 10. The upwardly extending security sensor causes a portion of the stack to be disposed an oblique angle 26, rather than lying flat. This uneven stack makeshandling of work in progress more difficult.
FIG. 3 illustrates a bard cover product 30 according to the present invention in which the security sensor 24 is concealed within an assembly of the outer liner 12, the sheets 14, 16, and the inner liner 18. FIG. 4 is an exploded edge view ofthe hard cover product assembly illustrated in FIG. 3. A recess 32 is formed in the sheet 14 such as by die cutting the sheet in a casing operation typical for binding of books using a casing machine. An applicator apparatus places the security sensor24 within the recess 32. The outer liner 12 closes the recess 32 from an exterior side of the assembly for the hard cover product 30, and the inner liner 18 closes the recess 32 from the opposing interior side. The inner liner 18 thereby conceals thesecurity device 24 within the hard cover product 30.
The thickness of the sheet 14 (on a line 34 shown in FIG. 4 transverse through the opposing major surfaces) is preferably sufficient that the security device 24 is recessed in the recess 32 relative to the major surfaces. The sheets 14, 16 arecardboard sheet, fiberboard sheets, or other stiff or hard sheet material suitable for forming a cover to a book, casing, or other article-container.
In the illustrated embodiment, the gap 22 defines scores or grooves in the overlapped inner and outer lines 12, 18. These define pivots or lines on which the front and back covers fold together.
FIG. 5 illustrates an alternate embodiment of a hard cover product 50 according to the present invention. In this embodiment, a substantially planner radio frequency tag 52 attaches to the surface of the sheet 14a. The inner liner 18 attachesin overlaying relation to the sheets 14, 16. In the illustrated embodiment, which does not include the recess 32, the inner liner 18 extends over the area of the spine. The inner liner 18 thereby overlies and concealingly encloses the sheet-likesecurity tag 52. The security tag 52 is perceptible as a slight bulge, but generally does not detract from the graphics or text on the inner liner.
In the illustrated embodiment, the hard cover product 50 attaches to an interior body, such as plastic matingly engagable plastic diskholders, configured for receiving compact discs or DVD discs. However, the interior body may be a boundassembly of papers for a book. Other shell devices that define an interior body for the hard cover product may be gainfully attached to the interior front and back covers, such as for packaging small articles, video tapes, books, ring binders, or otherarticles. For example, FIGS. 8A and 8b illustrate a bound assembly 61 of paper sheets containing printed material to be bound in the hard cover product as a book. The bound assembly 61 attaches to the spine 22.
FIG. 6 illustrates the hard cover product 50 in which the outer liner 12 includes an indicia 62 such as a bar code or other product inventory number. In this embodiment, the recess 32 for the security tag 24 (or security tag 52 attached to thesheet 14) is disposed substantially in alignment with the indicia 62. In this way, a security tag detector deactivates the security tag when the hard cover product 30 is scanned for pricing, so that the product can be taken from a store withouttriggering alarms.
FIG. 7 illustrates an alternate embodiment of a hard cover product 70 that includes a three-ring binder assembly 72. In this embodiment, the sheet 14 receives one of the sheet-like security devices 52, although in an alternate embodiment, thesheet defining front (or back) cover includes the recess 32.
FIG. 9 is a schematic illustration of an assembly line 90 for manufacturing hard cover products of the present invention discussed above. The assembly line 90 includes a supply hopper 92 that receives a stack 93 of interim assemblies of the hardcover product. A casing machine 94 operates to cut blanks of cardboard sheets to define the front and back cover bodies enclosed in the outer and inner liners. The casing machine 94 also includes a rotatatable cylinder 91 with a cutter 95 for slittingopen the recess 32. An interim assembly of the hard cover product includes the outer liner 12 attached to the sheets 14, 16. A label applicator 96 receives a supply of security tags 24 and positions one in the recess 32 or on the sheet 14 (for a sheettype security tag). Operation of the assembly line in a first stage of manufacture results in interim assemblies that are subsequently returned to the hopper for attaching the inner liner 18.
The assembly line 90 further includes an inner liner application station 97 in which the inner liner 18 is attached in overlying relation to the major surfaces of the sheets 14, 16 opposing the outer liner 12. A glue station 98 includes anadhesive applicator 100 for depositing a selected adhesive 101 to the inner liner 18. A casing applicator 102 includes a supply hopper 104 that holds a plurality of interior bodies or casings 103, such as the engageable shells 54, 56. A metering device106 causes one of the casings 103 to be positioned on the spine 22. Opposing ploughs 108 guide the opposing front and back covers to pivot together to foldingly close the hard cover product. Rollers 110 bear against the opposing covers to close thehard cover product and to force the casing 103 into engaging contact with the adhesive. The completed, closed hard cover product then is received in a stacker 112 for packaging.
While the hard cover product 10 described above provides the enclosed and concealed security sensor 24, the exterior surfaces of the outer liner 12 and the inner line 18 tend to include indications of the presence of the security sensor containedtherein. These indications include a subtle but noticeable border defined by the edge of the recess 32, a shallow depression in the outer liner 12 or the inner liner 18 in the proximity of the recess, or a shallowly bulging portion proximate to therecess. The present invention provides in another aspect as illustrated in FIG. 10, an intermediate laminated cover board 120 that does not display surface indications of the presence of the security sensor or device 32 enclosed within a hard coverproduct 122 assembled using the intermediate laminated cover board. The hard cover product 122 includes the outer liner 12, a cover board 124, the intermediate laminated cover board 120 disposed spaced apart therefrom, and an inner liner 18. The coverboard 124 and the intermediate laminated cover board 120 overlaid with the outer liner 12 and the inner liner 18 define front and back covers for the hard cover product, such as a book, a binder, a disc enclosure, or the like product having an interiorbody. A gap between the spaced apart cover board 124 and intermediate laminated cover board 120 define a spine for the hard cover product 122 that closes by folding the opposing cover boards along line defined by the spine.
With reference to FIGS. 11 and 12, the intermediate laminated cover board 120 (illustrated in perspective cut-away view and perspective exploded view, respectively), is gainfully used for assembling hard cover products 122. The intermediatelaminated cover board 120 includes a primary or central sheet 130 having opposing planar surfaces 132, 134 with a length and width exceeding a first thickness 136. The central sheet 130 further defines an opening 138 through the central sheet. Theopening 138 is formed by a die cutter such as a roller with an extending die that bears upon the cover board as it moves past the roller on a conveyor. The opening 138 is formed in a selected portion of the cover board, and particularly so that theouter cover 12 can be printed with an indicia such as a bar code that also directs the positioning of a security canceling device such as the scanners used at store checkout registers.
The security device 32 is received in the opening 138. In the illustrated embodiment, the security device 32 has a thickness generally no greater than about a substantial majority of the thickness of the central sheet 130, so that opposing sidesof the security device 32 are substantially co-planar with respective ones of the opposing planar surfaces 132, 134 of the central sheet, as best illustrated in cross-sectional view in FIG. 13, taken along line 13-13 of FIG. 10.
A pair of opposing exterior sheets 142, 144 attach with an adhesive as a lamination to respective opposing planar surfaces 132, 134 of the central sheet 130. The exterior sheets 142, 144 each have a respective second thickness that less than thefirst thicknessl36. The laminated exterior sheets 142, 144 thereby enclose the security device 32 in the opening 138 and between the exterior sheets. The thickness of the exterior sheets 142, 144 is sufficiently sized so that the laminated intermediatecover board 120 does not display surface indications of the presence of the security device 32. The security device 32 thereby enclosed in the central sheet 130 is concealed from casual indication of its presence.
The central board 130, as well as the exterior boards 142, 144 are made of a semi-rigid sheet material, such as chip board, pasted chip board, card board, grey fibreboard, or the like material used for cover boards for books, backings for notepads, and the like products.
With reference to FIGS. 11-13, the center board 130 and the exterior boards 142, 144 intermediate together to produce the laminated board 120 f)r subsequent use as a component of hard cover products. The central sheet 130 is provided with theopening 138 such as by a die cutter extending through the opposing surfaces in the selected portion. The exterior sheet 144 then laminates with an adhesive to the planar surface 134. This closes the opening 138 on one side. The security device 32 ispositioned in the opening 138. As illustrated in FIG. 13, the security device 32 preferably has a thickness no greater than about a substantial majority of the thickness of the central sheet 130 so that opposing sides are no more than substantiallyco-planar with the opposing planar surfaces 132, 134 of the central sheet. The second exterior sheet 142 laminates to the planar surface 132 to enclose the security device 32 and to form an intermediate laminated board 130 that does not display on theopposing surfaces defined by the exterior sheets indications of the presence of the security device in the intermediate laminated board 130.
In an example, the central board 130 has a length of 71/2 inches, a width of 53/4 inches, and a thickness of 0.060 inches. The opening 138 is cut 1 inch from the head of the central board 130 and is centered laterally. A commercially availabletype of security device has a thickness of about 0.056 inches. The exterior boards 142, 144 conform in length and width to the central board, and have a thickness of about 0.010 inches. In an alternate embodiment, the central board 130 can be left openon one side, by using one exterior board having a thickness of about 0.020 inches, which may be a less expensive embodiment of the invention. Other embodiments are readily apparent to those of ordinary skill in the art of forming hard cover products.
With reference to FIG. 10, the intermediate laminated cover board 130 readily assembles with the cover board 124, the outer cover 12, and the inner cover 18, as discussed above to form the foldable hard cover product 122 to enclose the securitydevice 32 while not having casually observable surface indications as to the security device.
FIG. 14 illustrates in perspective cut-away view an alternate embodiment of a intermediate laminated cover board 150 using a sheet-type security device such as the planar radio frequency tag 52 while not displaying surface indications of thepresence the security device. FIG. 15 illustrates in cross-sectional exploded side view the intermediate laminated cover board 150 which defines a shallow recess 154. The recess 154 has a bottom surface and is formed in the cover board by a debossprocess. The recess 154 results from passing the cover board 152 between a roller having a projection and a pressure plate, which projection compresses the selected portion of the cover board in order to define the shallow recess 154 therein. Therecess 154 thereafter receives one of the planar radio frequency tags 52. The depth of the deboss recess 154 is about the thickness of the radio frequency tag 52, but generally is sufficiently compressed so that an exterior surface of the radiofrequency tag 52 is coplanar or recessed relative to a surface of the cover board 152 around the recess. A liner board 156 attaches with adhesive in overlaying relation and enclosing the radio frequency tag 52 in the recess with little if any exteriorsurface indication of the presence of the security device enclosed within the laminated structure. It is to be appreciated that with respect to FIG. 15, the security sensor (radio frequency tag 52) is totally concealed before a cover 12 and inner liner18 are applied. The intermediate cover board 150 may also be supplied to a manufacturer of hard cover products (such as a book binder) without the laminated cover liner 156 for application by the binder of the cover 12 and liner 18. This alternateembodiment with the recess 154 may have slight surface indications of the security tag after application of the cover 12.
FIG. 16 illustrates in perspective exploded view an alternate embodiment of an intermediate cover board 160 that accommodates a combination security device 166. The cover board 160 defines a slot 162 and an adjacent recess 164. The slot 162 isdie cut through the cover board 160 while the recess 164 is debossed therein as discussed above. The combination security device 166 includes a backing sheet 168 with an acoustic magnetic security bar 170 and a planar radio frequency tag 172. Aperimeter portion of the combination security tag 166 includes an adhesive coating 173.
For purposes of illustration, FIG. 16 illustrates the combination security tag 166 with the security bar 170 and the planar radio frequency tag 172 disposed in a direction away from the cover board 160. When installed, the combination securitydevice 166 is disposed towards the cover board 160 with the security bar 170 received in the slot 162 and planar sheet radio frequency tag 172 disposed in the recess 164, respectively. The adhesive coating 173 on the perimeter secures the combinationsecurity tag 166 in place.
While not illustrated, it is to be appreciated with reference to FIG. 11 and 12 that the combination security tag 166 can be enclosed by laminating a cover liner 142 to the cover board 160, and further in an alternate embodiment, a pair ofopposing cover boards 142, 144 can be laminated to opposing sides of the cover board 160. The embodiment illustrated in FIG. 16 is gainfully used in facilities (such as stores or libraries, as examples) having one or both of such security detectiondevices. The intermediate cover board 160 including the security device 166 is provided to manufacturers of hard cover products for applying cover liners 12 and inner liners 18. The resulting hard cover product has reduced surface indications of thepresence of the hidden enclosed security device or with the cover liner 142, 144, the product lacks observable indications of the enclosed security device. The manufacturer of hard cover products can select an embodiment having the cover liners 142,144, or the single layer intermediate cover board.
This specification has described the present invention that provides the intermediate laminated cover board useful in making hard cover products with concealed security devices, including the steps necessary for making and using variousembodiments thereof. It is to be understood, however, that numerous changes and variations may be made in the construction of the present hard cover product within the spirit and scope of the present invention, and that modifications and changes may bemade therein without departing from the scope thereof as set forth in the appended claims.
