To enhance customer satisfaction in use of an extruding container of an
applying filler, a leading tube having a discharge port (101c) is formed
as a filling member (101), and the filling member (101) having a filling
region (101x) filled with an applying filler (L) is inserted and attached
to a leading end side of a main body side assembly (140) formed by
installing a movable body (106), an engagement portion (104c, 106b) for
moving the movable body (106) and a rotation preventing portion (102d,
106e), whereby the applying filler (L) can be sufficiently filled in the
region (101x) between the inner side of the discharge port (101c) of the
filling member (101) and the movable body (106) of the main body side
assembly (140), and the applying filler (L) can be rapidly discharged at
a first applying time by a user.
