PROBLEM TO BE SOLVED: To apply functions for preventing an extremely thin wrap from sticking to a face in contact with a box and forming a space between the wrap and the face in contact with the box to raise the wrap. SOLUTION: In order to prevent an extremely thin wrap from sticking to an a-face in contact with a box 1, a member having a spring function (function board 4) is inserted below the wrap 5, so that when there is no pressure from above, the wrap is raised by spring effects to form a space between the a-face in contact with the box and the wrap to assure that the film can be pinched between fingers and easily pulled out at the time of using the film for the next time. A tip of the function board having spring effects is positioned at the side of a wrap take-out port of the box from a cut line in order to make a margin for pinching the wrap between fingers, and for the purpose of further increasing the margin, the function board for raising the wrap has such a shape that the tip is not linear but wavy or with a deep cut part.
