When the wet tissue 41 is used, by pressing the horizontal plate 90 from above, the vertical plate 92 connected to the horizontal plate 90 can be bent around the lower end thin portion 91c without bending the outer frame 33. Thereby, the engagement between the locking piece 32 and the engagement protrusion 79 can be released. In this case, the horizontal plate 90 and the vertical plate 92 are partitioned from the other portion 33a and the step portion 28a of the outer frame 33 by the thin portion 91, respectively, and the thin portion 91 is surrounded by a pair of ribs 94 and 95. Therefore, even if the horizontal plate 90 is pressed and the vertical plate 92 is bent, the pressing force of the horizontal plate 90 is transmitted to the other portion 33a of the outer frame 33 and the other portion 28a of the step portion 28. Absent. Therefore, when the vertical plate 92 is bent, the other portion 33a of the outer frame 33 and the other portion 28a of the step portion 28 are not greatly bent. When the engagement between the locking piece 32 and the engagement protrusion 79 is removed, the opening / closing lid 23 is rotated about the swing shaft 77 by the restoring force of the rubber plate 50, and the opening / closing lid 23 is opened.
[0031]
Next, the wet tissue 41 is picked with a finger from the outlet 24 of the lid body 21 and pulled upward. Thereafter, the first wet tissue 41 can be taken out from the container body 11 by continuously pulling the wet tissue 41. In this case, the upper half 41 a of the second wet tissue 41 is pulled by the lower half 41 b of the first wet tissue 41. Then, when the upper half 41a of the second wet tissue 41 is caught on the peripheral edge 24a of the outlet 24, the second wet tissue 41 stops.
[0032]
As described above, according to the present embodiment, by pressing the horizontal plate 90, the vertical plate 92 connected to the horizontal plate 90 is bent without greatly bending the other portion 33a of the outer frame 33. The engagement between the engagement protrusion 79 provided on the vertical plate 92 and the locking piece 32 of the opening / closing lid 23 can be directly and reliably released.
[0033]
【The invention's effect】
According to the present invention, since the vertical plate connected to the horizontal plate is bent by pressing the horizontal plate, the engagement between the engagement protrusion provided on the vertical plate and the locking piece of the opening / closing lid is directly and It can be released reliably. Therefore, the contents can be reliably taken out by opening the opening / closing lid.
