Information folder construction

Claim 1

A folder construction comprising an elongate strip of thin flexible paper folded assymetrically about a transverse line to form a crease along said line and a pair of overlying leaves of different lengths extending from said crease and terminating at strip ends spaced different distances from said crease, said strip being wound from said crease outwardly to form a spiral having many ovaloid convolutions with each convolution having its entire outer surface in facing engagement with the inner surface of the next outer convolution, said convolutions each having arcuate end portions and side portions extending between said end portions, said convolution end portions each being in reinforcing abutting engagement with the convolution end portions of the next outer convolution for cumulative stiffening of the outward convolution end portions, said strip ends being detachably secured to the nether convolutions, detachment of the strip ends enabling unwinding of said spiral convolutions, said strip being wound with the longer leaf outwardly to overlie the shorter leaf and its strip end, and releasable adhesive detachably securing the strip end of said outwardly wound longer leaf to the nether convolution, said strip ends both terminating in the outermost convolutions in adjacent relation with respect to each other and overlying the same convolution side portion, whereby detachment of the outer strip end presents immediately therebeneath the inner strip end.
