[Effect of the invention]
In the chemical liquid applying step by the nozzle type injection method as shown in FIG. 4, the liquid medicine passes through the space S in the center of the roll-shaped sanitary sheet P (FIG. 5: step 1). However, due to the presence of the projections 12, the roll-shaped sanitary sheet P is in a state of floating from the bottom surface, so that the unimpregnated chemical solution accumulates on the bottom surface (FIG. 5: step 2). Therefore, in the chemical application step, it is possible to prevent impregnation from the bottom side as well, prevent excessive impregnation of the central portion of the roll-shaped sanitary sheet P in the initial state, and prevent the central portion and the outer circular portion from being impregnated with the chemical solution. A difference in impregnation amount can be reduced.

Further, as the roll-shaped sanitary sheet P is used from the center, the diameter of the space S of the roll-shaped sanitary sheet P becomes larger than the diameter of the upper surface of the protrusion 12 . Then, the roll-shaped sanitary sheet P falls on the bottom surface (FIG. 5: step 3). As a result, the roll-shaped sanitary sheet P comes into contact with the chemical liquid accumulated on the bottom surface and is impregnated. Therefore, the roll-shaped sanitary sheet P is impregnated during use, reducing the difference in the amount of chemical solution impregnated between the already used circular center portion of the roll-shaped sanitary sheet P and the outer circular portion to be used from now on. can do.

[Modification]
Although the present invention has been specifically described above based on the embodiments, the present invention is not limited to the above embodiments, and can be modified without departing from the scope of the invention.

For example, as shown in FIGS. 6 and 7, the protrusions 12A and 12B may have a shape in which a plurality of columns are stacked.
As shown in FIG. 6, the protrusion 12A is a stepped columnar body with a diameter larger than that of the columnar body on the bottom side. It will happen. In this case, the upper surfaces of the columns in the first and second stages function as support portions.
As shown in FIG. 7, the diameters of the projections 12B are small, large, and small from the upper surface side, and the diameter of the column is smaller than the diameter of the space S of the unused roll-shaped sanitary sheet P. In this case, the upper surface of the second column functions as a support. In this case, the horizontal movement of the roll-shaped sanitary sheet P can be suppressed by the columns on the first stage on the upper surface side, and the roll-shaped sanitary sheet P can be stably supported.

For example, as shown in FIG. 8, protrusion 12C may be a cone. In this case, as the roll-shaped sanitary sheet P is used from the center, it gradually falls off. And the side surface of the cone functions as a support.

For example, as shown in FIG. 9, protrusion 12D may be a frustum. In this case, as the roll-shaped sanitary sheet P is used from the center, it gradually falls off. Then, the side surface of the frustum functions as a support.

For example, as shown in FIG. 10, the protrusion 12E may have a shape in which a cone is superimposed on a column. Note that frustums may be overlapped. In this case, the side surface of the cone or frustum functions as a support.

Also, the protrusion 12 may be hollow or solid.

Moreover, the protrusion 12 is not limited to the cylinder, cone, and truncated cone shown in FIGS.

Moreover, the shape of the sanitary sheet storage container 100 does not necessarily have to be a cylindrical shape, and for example, it may be formed in a prismatic shape such as a pentagonal shape or a hexagonal shape in a plan view.
Moreover, the extraction part 3 may be detachable from the lid 2 or may be fixed.
