  The shape of the outlet 24 (mouse portion) is not limited to that shown in FIG. 1. For example, as shown in FIG. 18, a flap is formed around the outlet 24 in a recess 94 provided in the first upper plate 27 a. 39 may be provided.

  Next, the operation of the present embodiment having such a configuration will be described.

  When using the wet tissue 41, the user first presses the top plate portion 65 of the operation button 55. As a result, the engagement between the locking piece 32 and the claw portion 66 is released. In this case, the opening / closing lid 23 is opened by the restoring force of the rubber plate 50.

  That is, the opening / closing lid 23 is biased by the rubber plate 50 and rotates in the opening direction (clockwise direction in FIG. 12) about the swing axis XX.

  During this time, the action of the spring body 34 and the slope portion 43 is as follows. First, in the fully closed state shown in FIG. 12, the spring body 34 is located away from the back side step portion 25 and the slope portion 43 of the container body 11.

  Next, when the opening / closing lid 23 is rotated in the opening direction by the restoring force of the rubber plate 50, the spring body 34 is also moved to the slope portion 43 side, and the spring body 34 comes into contact with the inner surface 43a of the slope portion 43. (See FIG. 14).

  Subsequently, when the opening / closing lid 23 further rotates, the spring body 34 rises toward the fully open point 43 c along the inner surface 43 a of the slope portion 43.

  In this case, as described above, the distance between the inner surface 43a of the slope portion 43 and the swing axis XX gradually decreases from the lower end portion 43b to the full open point 43c. Accordingly, the spring body 34 is gradually compressed as it rises along the slope portion 43 (see FIG. 14). By compressing the spring body 34 in this manner, the rotation speed of the opening / closing lid 23 is suppressed against the urging force of the rubber plate 50.

  Thereafter, when the opening / closing lid 23 reaches the fully open position, the base end edge 23d of the opening / closing lid 23 is locked to the stopper 30 and the opening / closing lid 23 stops (see FIG. 13).

  At this time, as shown in FIG. 13, the actual shape (indicated by the solid line) of the spring body 34 is compressed compared to the original shape of the spring body (reference numeral 34X) indicated by the phantom line. Thus, the spring body 34 applies a restoring force to the slope portion 43, so that the rotational speed of the open / close lid 23 can be suppressed and the open / close lid 23 can be gently stopped at the fully open position.

  Next, the wet tissue 41 is picked with a finger from the outlet 24 of the container body 11 and pulled upward to be used.

  As described above, according to the present embodiment, before the opening / closing lid 23 is fully opened, the spring body 34 of the opening / closing lid 23 gradually moves along the inner surface 43a of the slope portion (braking portion) 43 of the container body 11. Compressed. Thereby, the opening / closing lid 23 can be decelerated little by little, and can be gently stopped at the fully opened position. Therefore, after the opening / closing lid 23 comes into contact with the stopper 30, the opening / closing lid 23 can be immediately stopped without vibrating.

  Further, according to the present embodiment, the mechanism for gently stopping the opening / closing lid 23 at the fully open position is simple. That is, since the spring body 34 can be integrally formed with the open / close lid 23 and the slope portion 43 can be integrally formed with the container body 11, such a mechanism can be easily realized at low cost. .
