Document Type and Number:
Japanese Patent JP3802893
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a simply structured film holder, in which a large number of sheets of film are stably housed and stored, the insertion of film in which is easy, no local breakage develops even after the repeated insertion and housing of film and which can use over a long period of time.
SOLUTION: By fixing the peripheral edge of a transparent synthetic resin sheet 2 with a predetermined size, on the under surface of which a transparent synthetic resin sheet 3 with the same size, with a thermal welding line 12, a large number of film housing divisions 4 are dividingly formed with discontinuous thermal welding lines 10 within the sheets. Within the sheets, film housing parts 6, each having a triangular bellows part 15. At the corner 16 of the triangular bellows part 15, a folding line 17 is formed. In addition, at the basic end parts of a lengthwise line 13 and of a lateral line 14, curved line parts 18 and 18 are formed.
