[Ejection section]
As shown in FIGS. 4 and 5, the take-out portion 3 is an elastically deformable member formed in a substantially cylindrical shape that is circular in a plan view. Note that FIG. 5 is a bottom view of the take-out portion 3, showing a mode in which the take-out portion 3 of FIG. 4 is viewed from below.
Specifically, the take-out portion 3 is formed in a concave portion 31 having an internal bottom surface 3a formed in the central portion in a plan view, a constricted portion 32 formed in a side surface, and a substantially central portion in a plan view of the concave portion 31 (internal bottom surface 3a). The take-out hole 33 is provided, and a chamfered portion 34 formed by chamfering the peripheral edge portion of the take-out hole 33 on the lower surface 3b.
Further, the thickness (dimension between the inner bottom surface 3a and the lower surface 3b) R1 (see FIG. 6) in the Z-axis direction below the constricted portion 32 in the take-out portion 3 is 1.0 mm to 5.0 mm, preferably 1. It is formed so as to be 5 mm to 3.0 mm.

(Recess)
The recess 31 is formed on the upper surface of the take-out portion 3 so as to be concave downward in a circular shape in a plan view, leaving a peripheral edge portion. Further, the recess 31 is formed so that the inner bottom surface 3a thereof is flat.
Further, the recess 31 is formed so that the inner bottom surface 3a thereof is flat.

(Constriction)
The constricted portion 32 orbits the substantially central portion of the side surface of the take-out portion 3 in the vertical direction along the circumferential direction, and has a depth of 1/20 or more and 1/10 or less of the diameter of the take-out portion 3 in a plan view. It is formed in a groove shape that is recessed in the radial direction so as to be. As described above, since the take-out portion 3 is formed to be slightly larger than the hole portion 21d in a plan view, the take-out portion 3 can be attached to the lid body 21 by fitting the edge of the hole portion 21d into the constricted portion 32. It can be fixed.

(Outlet hole)
The take-out hole 33 is a hole for taking out a sheet of sanitary thin paper P stored inside the container body 1.
The take-out hole 33 holds the sheet inserted from the lower surface 3b side in a state where the tip thereof protrudes from the upper surface (inner bottom surface 3a of the recess 31) of the take-out portion 3.
When the tip of the sheet protrudes from the upper surface of the take-out portion 3, the amount of protrusion thereof is 5 mm to 39 mm, preferably 13 mm to 20 mm. When the amount of protrusion is 5 mm or more, it can be easily picked up by a general user's fingers, and the taking-out work can be easily performed. Further, since the protrusion amount is 39 mm or less, the edge portion of the sheet does not protrude from the lid body 2 when the lid body 2 is closed.

Further, the take-out hole 33 is formed by a notch 330 in which two straight lines intersect in a cross shape at the substantially center of the take-out portion 3 in a plan view.
As shown in FIG. 5, for example, the cut portion 330 is formed at the four straight portions 331, the first circular portion 332 provided at the portion where one end of the straight portion 331 intersects, and the other end of the straight portion 331. It has a second circular portion 333, which is provided and has a diameter smaller than that of the first circular portion 332.
The total length of the cut portion 330 is formed to be 5 mm to 30 mm, preferably 10 mm to 15 mm, and is set to, for example, about 15 mm, which is equal to or larger than the width of the index finger of a general user. By forming the cut portion 330 by the cross-shaped cut in this way, the certainty of holding the sheet in the cut portion 330 can be further enhanced.
The diameter of the first circular portion 332 is formed to be 2.5 mm to 4.0 mm, and by providing the first circular portion in this way, the protrusion held by the take-out portion 3 after the sheet is taken out is lengthened. Can be done. Further, by providing the second circular portion, the sheet can be taken out with a smaller force.

Although the case where the take-out hole 33 is formed in a cross shape is illustrated and described in FIG. 5, the shape of the take-out hole 33 is not limited to this, and any shape can be obtained as long as the above functions can be achieved. Can be selected. That is, radial cuts may be formed by three or more linear cuts. Further, the take-out hole 33 may be formed by one linear notch, or may have a circular shape, an elliptical shape, a substantially star shape, or the like.

(Chamfering part)
As shown in FIGS. 5 and 6, the chamfered portion 34 is a region where the corner formed by the lower surface 3b of the take-out portion 3 and the hole wall 33a of the take-out hole 33 is chamfered.
Specifically, the chamfered portion 34 is a flat chamfered portion in which the edge portion of the hole wall 33a of the take-out hole 33 is chamfered on the lower surface 3b of the take-out portion 3 with an inclined flat surface. The opening area on the lower end side is larger than the opening area on the upper end side.
As shown in FIG. 7, the size of the chamfered portion 34 is such that the length L1 of the take-out hole 33 in the XY plane direction from the hole wall 33a of the take-out hole 33 is within the range of 0.5 mm to 1.0 mm. It is preferable that the length L2 in the Z-axis direction from the lower end is set within the range of 0.5 mm to 1.0 mm.

Here, the case where the chamfered portion 34 is formed by chamfering on a flat surface has been illustrated and described, but as the chamfered portion 34, as shown in FIG. 8, the lower surface 3b of the take-out portion 3 and the take-out hole 33 are used. The corner formed by the hole wall 33a may be a curved surface chamfered portion that is chamfered so as to be a convex curved surface.

The above-mentioned take-out portion 3 must be inserted into the hole portion 21d and must not come off from the lid body 21 when the sanitary tissue paper storage container 100 is used, and a sheet can be inserted into the take-out hole 33 with a finger. Since it is necessary to be able to push in, it must be formed using a material having a certain elasticity. Specifically, the hardness is preferably 50 to 70, and for example, elastomers such as styrene-butadiene-based, polyester-based, polyethylene-based, and urethane-based elastomers can be used and are formed by injection molding. The hardness is measured by JIS K 6253 (Type A durometer).

Further, when coloring the take-out portion 3, for example, a resin such as PE (polyethylene) mixed with an arbitrary pigment is mixed with an elastomer (pigment addition step). At this time, by changing the mixing ratio of the elastomer and the resin PE, the sheet take-out performance by the take-out unit 3 can be adjusted.
Here, the resin mixed with the elastomer may have a hardness higher than that of the elastomer.

Further, when the force required when pulling out the sheet in the take-out unit 3 is measured 5 times using a digital force gauge (manufactured by IMADA: model number DS2-200N) and the average value is defined as the resistance value, the resistance value is obtained. The value of is preferably in the range of 5N to 12N, more preferably 6N to 10N.
In addition, when a single roll of thin paper for hygiene P (for example, a series of 80 sheets having 79 perforations) is pulled out, the perforations are not cut and the subsequent sheets are not cut. The permissible range of the number of times (the number of consecutive times) the sheets of No. 1 are continuously ejected is 10 times or less, and preferably 7 times or less.

[Effect of Embodiment]
Hereinafter, the main effects that can be obtained by the present embodiment will be described.

As shown in FIG. 10, in the case of the conventional hygienic tissue paper storage container 200, when the sheet of roll-shaped tissue paper P is pulled out from the center thereof, the sheet is pulled out in a rotating manner, which is inevitable. The sheet is twisted in a certain direction (in FIG. 10, a counterclockwise direction with the Z-axis direction as the rotation axis).
However, as shown in FIG. 9, the sanitary thin-leaf paper storage container 100 of the present embodiment is provided with a rotation mechanism 12 on the bottom surface that can rotate about the Z-axis direction as a rotation axis by an external force, so that the sheet is twisted. Even if it is pulled out from the center of the roll, when it is pulled out, the mounting plate 121 and the sanitary thin leaf paper P rotate in the same direction as the twist of the sheet (counterclockwise direction with the Z-axis direction as the rotation axis). Will be done.

As a result, the twist is eliminated when the sheet is pulled out, and the taken-out sheet is unlikely to be in a twisted state. Therefore, it is not necessary to unfold the sheet before use, and the taken-out sheet has creases and habits. Since it is difficult, it is possible to prevent the sheet from curling during use.
Further, if the sheet passes through the take-out hole 33 in a twisted state, it may be caught in the take-out hole 33 and it may be difficult to take out the next sheet. Therefore, such a risk can be reduced.

[Modification example]
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 gist thereof.
For example, when the rotating portion 122 is a caster, the number of rotating portions 122 is not limited to four as shown in FIG. 3, but considering the stability of the support of the sanitary tissue paper P by the mounting plate 121. , It is preferable that at least three or more are provided at substantially equal intervals.

Further, the shape of the hygienic tissue paper storage container 100 does not necessarily have to be a cylindrical shape, and may be formed into a prismatic shape such as a pentagon or a hexagon in a plan view.
Further, the take-out portion 3 may be detachably attached to or fixed to the lid body 2.
