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 the 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 in the substantially center of the plan view of the take-out part 3.
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 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, it is desirable that the hardness is 50 to 70. Specifically, for example, styrene-butadiene-based, polyester-based, polyethylene-based, urethane-based and other elastomers can be used and formed by injection molding. NS. 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 this embodiment)
In the present embodiment, for example, as shown in FIG. 3, the height of the inner portion 122 including the central portion of the bottom surface portion of the container main body 1 is higher than the outer portion 121 of the container main body with which the outer edge portion of the sanitary thin paper P abuts. A mounting portion 12 formed so as to be low is provided on the container body 1, and a roll-shaped thin paper for hygiene P is placed on the mounting portion 12, so that the upper part of the roll is centered from the side surface. You will receive the power to go.
In such a container body 1, if the sanitary tissue paper P is taken out in order from the core side and used, the shape holding force of the hygiene tissue paper P decreases as the inner diameter of the roll increases. Therefore, as shown in FIG. 9, the roll The upper part bends toward the center and approaches the take-out hole 33 provided at substantially the center of the top surface of the container body 1.
In this way, even when the amount of the sheet is reduced, the upper part of the roll continues to be located near the take-out hole 33, so that the take-out part 3 can easily hold the end portion of the sanitary tissue paper P and falls into the container body 1. It becomes difficult.

[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, as shown in FIGS. 3 and 9, the mounting portion 12 is not limited to a shape that is inclined toward the center portion of the bottom surface portion, and a height difference is provided between the outer portion 121 and the inner portion 122 of the container body 1. The shape of the roll-shaped tissue paper P placed on the mounting portion 12 may be such that the upper portion receives a force from the side surface toward the center. For example, the container body as shown in FIG. The shape may be such that a substantially inverted truncated cone is cut out from the bottom surface portion, which is inclined downward from the outer portion 121 to the inner portion 122 of 1.
By doing so, the amount of members required for forming the mounting portion 12 can be reduced.
Further, the mounting portion 12 does not have to have a shape inclined downward, and may have a stepped shape having a step downward toward the inner portion 122.

The shape of the hygienic tissue paper storage container 100 does not necessarily have to be cylindrical, and may be formed in 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.
Further, the hygienic thin paper P may be a wet sheet impregnated with a chemical solution or a dry sheet.
