Patent ID: 7183918

Claim:
A hard cover product, comprising: an outer liner; a pair of cover boards disposed in spaced-apart relation to define a spine for a hard cover product while defining opposing cover boards therefor and each attached on a respective major surface to a major surface of the outer liner; at least one of the cover boards comprising: a central sheet having opposing surfaces with a length and width exceeding a first thickness, the central sheet defining an opening therethrough in a selected portion thererof; a security device received 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 substantially co-planar with respective ones of the opposing planar surfaces of the central sheet; and a pair of opposing exterior sheets, each having a respective second thickness less than the first thickness laminated to the opposing planar surfaces of the central sheet and thereby enclosing the security device therebetween, the second thickness sufficiently sized so that the laminated board does not display surface indications of the presence of the security device therein, whereby the security device enclosed in the central sheet is concealed from casual indication of its presence; and an inner liner attached in overlying relation to the opposing planar surfaces of the cover boards, whereby the opposing cover boards define a front cover and back cover that move together foldably along lines defined by opposing sides of the spine for the hard cover product.
