The edge cleat is adapted to be attached around an edge of a merchandise box, the merchandise box having a first structural portion and a second structural portion that are connected to one another along the edge, such that a first portion of the edge cleat is disposed against the first structural portion of the merchandise box and a second portion of the edge cleat is disposed against the second structural portion of the merchandise box. The tag assembly interlocks with the edge cleat and includes an electronics assembly, contained within a housing, that forms at least part of an alarm system. The electronics assembly may include an electronic article surveillance (EAS) tag. ## Claims ### Claim 1 A box edge security device, for a merchandise box having adjacent structural portions connected together along an edge, comprising: an edge cleat adapted to be attached around an edge of the merchandise box, the merchandise box having a first structural portion and a second structural portion that are connected to one another along the edge, such that a first portion of the edge cleat is disposed against the first structural portion of the merchandise box and a second portion of the edge cleat is disposed against the second structural portion of the merchandise box; and a tag assembly that interlocks with the edge cleat and includes an electronics assembly, contained within a housing, that forms at least part of an alarm system; wherein the edge cleat is electrically conductive and forms a sense loop that is broken if the edge cleat is removed from the merchandise box. ### Claim 2 (depends on 1) The box edge security device of claim 1, wherein the electronics assembly includes an electronic article surveillance (EAS) tag. ### Claim 3 (depends on 1) The box edge security device of claim 1, wherein the tag assembly includes a lock plug that biased into engagement with the edge cleat and an aperture that engages the lock plug. ### Claim 4 (depends on 1) The box edge security device of claim 1, wherein the tag assembly includes a box sensor that detects the proximity of a merchandise box to the tag assembly. ### Claim 5 (depends on 5) The box edge security device of claim 5, wherein the box sensor includes a spring-loaded plunger that extends through an aperture in the edge cleat and contacts a surface of the merchandise box. ### Claim 6 (depends on 1) The box edge security device of claim 1, wherein the edge cleat includes two flat portions arranged at a right angle to one another and adapted to fit around the edge of a merchandise box whose first and second structural portions are flat. ### Claim 7 (depends on 6) The box edge security device of claim 6, wherein respective interlocking structures are provided near the periphery of the underside of the tag assembly and on an outwardly-facing surface of one of the two flat portions of the edge cleat, respectively, such that the tag assembly can be coupled to the edge cleat by sliding the tag assembly onto the edge cleat by sliding the respective interlocking structure of the tag assembly onto the respective interlocking structure of the edge cleat. ### Claim 8 (depends on 7) The box edge security device of claim 7, wherein the underside of the tag assembly includes a recessed groove near its periphery, wherein the edge cleat includes a profiled edge on the outwardly-facing surface, and wherein the recessed groove of the underside of the tag assembly couples with the profiled edge of the edge cleat to interlock the tag assembly to the edge cleat. ### Claim 9 (depends on 7) The box edge security device of claim 7, wherein the tag assembly includes a lock plug that is biased into engagement with the edge cleat such that the once the tag assembly is fully coupled onto the edge cleat by sliding the tag assembly onto the edge cleat via the interlocking structures of the tag assembly and the edge cleat, respectively, the tag assembly cannot be removed from the edge cleat until the lock plug is manually disengaged from the edge cleat. ### Claim 10 (depends on 6) The box edge security device of claim 6, wherein an outwardly-facing surface of one of the first and second structural portions of the edge cleat includes a flat channel that accommodates a strap around the merchandise box. ### Claim 11 (depends on 10) The box edge security device of claim 10, wherein a raised protuberance is arranged on each side of the flat channel and extends up into a recess in an underside of the tag assembly to prevent the box edge security device from being moved sideways relative to the strap. ### Claim 12 (canceled) ### Claim 13 (depends on 6) The box edge security device of claim 6, wherein the edge cleat is initially provided in a flat, unfolded configuration and is bent, folded, creased, or otherwise manipulated to fit around the edge of the merchandise box. ### Claim 14 (depends on 1) The box edge security device of claim 1, wherein the electronics assembly includes a user-perceptible alarm, and wherein removal of at least one of the edge cleat and the tag assembly from the merchandise box triggers the alarm. ### Claim 15 A security device, for a merchandise box, comprising: a cleat; a tag assembly that interlocks with the cleat and includes an electronics assembly, contained within a housing, that forms at least part of an alarm system; and a conductive sense loop that is electrically connected to circuitry in the tag assembly such that the alarm system is triggered if the conductive sense loop is broken; wherein the cleat, tag assembly, and conductive sense loop are adapted to be attached to a first structural portion of the merchandise box. ### Claim 16 (depends on 15) The security device of claim 15, wherein the conductive sense loop is embodied in a conductive sense layer attached directly to the first portion of the merchandise box. ### Claim 17 (depends on 15) The security device of claim 15, wherein the alarm system is triggered if the conductive sense layer is broken or the tag assembly or the tag assembly is removed from the conductive sense layer. ### Claim 18 (depends on 15) The security device of claim 15, wherein the conductive sense layer is attached directly to the first structural portion of the merchandise box, wherein the cleat is attached over the conductive sense layer, and wherein the tag assembly is attached to the cleat. ### Claim 19 (depends on 18) The security device of claim 18, further comprising a protective layer that is attached to, and covers, the conductive sense layer, and wherein the cleat is attached to the protective layer. ### Claim 20 (depends on 15) The security device of claim 15, wherein the conductive sense layer is a conductive ink. ### Claim 21 An edge cleat for a merchandise box that includes having adjacent first and second structural portions connected together along an edge, comprising: a first portion adapted to be disposed against a first structural portion of the merchandise box; a second portion adapted to be disposed against a second structural portion of the merchandise box, wherein the first structural portion and the second structural portion are connected to one another along an edge, and wherein the edge cleat is adapted to be attached around the edge; one or more interface structures or elements that are adapted to interlock with a tag assembly; wherein a top or outer surface of the first portion of the edge cleat includes a shallow channel for receiving a strap; and wherein a top or outer surface of the second portion of the edge cleat also includes a shallow channel, collinear with the shallow channel of the first portion of the edge cleat, for receiving the strap; wherein the edge cleat is electrically conductive and configured to form a sense loop that is broken if the edge cleat is removed from the merchandise box.
