Claim 19:
20. A pivoting pop up article, comprising:
an exterior cover having a hinge fold positioned between a front cover and a rear cover for pivoting said front cover between a dosed position and an open position;
said front cover having an obverse side and a reverse side;
said rear cover having an obverse side and a reverse side;
a displacement leaf including a base, a leg and a tab;
a base leaf couple securing said base of said displacement leaf to said reverse side of said front cover;
said base being offset relative to said hinge fold for defining a base offset dimension between said hinge fold and said base,
an interior leaf having an obverse side, a reverse side, an inner edge and an outer edge;
a first interior couple securing said reverse side of said interior leaf to said obverse side of said rear cover,
a second interior couple securing said reverse side of said interior leaf to said obverse side of said rear cover;
said first interior couple and said second interior couple defining a channel between said rear cover and said interior leaf;
said base offset dimension causing said displacement leaf to be pivoted within said channel during pivoting said front cover between said closed position and said open position for extending said tab above said rear cover;
a displacement leaf perforation between said base and said leg for facilitating said interior leaf to be pivoted within said channel during pivoting said front cover between said closed position and said open position;
said displacement leaf perforation being offset relative to said hinge fold for defining a perforation offset dimension between said hinge fold and said displacement leaf perforation;
a frangible interior couple securing said obverse side of said interior leaf with said reverse side of said front cover;
said frangible interior couple being offset relative to said hinge fold for defining a frangible offset dimension between said hinge fold and said base; and
said base offset dimension, said perforation offset dimension and said frangible offset dimension defining an equivalent offset dimension for facilitating bending of said displacement leaf at said displacement leaf perforation before said displacement leaf begins pivoted within said channel.
