发明名称 ALBUM BLOCK BOARD
摘要 PROBLEM TO BE SOLVED: To provide a lightened album block board. SOLUTION: An album block board 11 is equipped with a pasting part 12, a hinge part 13 and a binding allowance part 14. The stock material of the pasting part 12 is a foamed paper, the density of which is 0.1 to 0.3 g/cm3. The pasting part 12 and the binding allowance part 14 are connected together with the hinge pat 13. Since the stock material of the pasting part 12 is the foamed paper, this album block board is made lighter than the conventional album block board, in which a cardboard or the like is employed, resulting in lightening a burden for handling an album.
