An opening (18) for withdrawing an elongated material thereform is formed in the portion of a wall (12) of a case (10, 10A), in which a flexible elongated material (50) is stored, which is close to an open end (14) of the case, and a first recess (22) in the same wall so as to extend from the portion of the open end in the lengthwise direction of the case and terminate in a position spaced from the opening. The first recess is capable of receiving therein an elongated material withdrawn through the opening. A second recess (30) extending from the portion of the open end of the case which is circumferentially spaced from the first recess, in the lengthwise direction is formed in the wall of the case. The second recess is provided at the bottom side thereof with a cutter (40). The elongated material withdrawn and passed through the first recess and inserted forcibly into the second recess can be cut with this cutter.
