It is formed in the shape of a groove concave in the radial direction. As mentioned above, the take-out part 3 is formed to be slightly larger than the hole 21d in plan view, so by fitting the edge of the hole 21d into the constricted part 32, the take-out part 3 can be attached to the lid main body 21. It becomes possible to fix it.

(Ejection hole)
The take-out hole 33 is a hole for taking out the sanitary tissue paper P stored inside the container body 1.
The ejection hole 33 holds the sheet inserted from the lower surface 3b side with its tip protruding from the upper surface of the ejection portion 3 (inner bottom surface 3a of the recess 31).
When the tip of the sheet protrudes from the upper surface of the take-out section 3, the amount of protrusion is 5 mm to 39 mm, preferably 13 mm to 20 mm. By having a protruding amount of 5 mm or more, it is easy for a general user to pick up the product with their fingers and take out the product easily. Further, since the amount of protrusion is 39 mm or less, the end portion of the sheet does not protrude from the lid 2 when the lid 2 is closed.

Further, the extraction hole 33 is formed by a notch 330 in which two straight lines intersect in a cross shape approximately at the center of the extraction portion 3 in a plan view.
For example, as shown in FIG. 5, the cut portion 330 includes four straight portions 331, a first circular portion 332 provided at the intersection of one end of the straight portion 331, and a first circular portion 332 provided at the other end of the straight portion 331. A second circular portion 333 is provided and has a smaller diameter than the first circular portion 332.
The total length of the notch 330 is 5 mm to 30 mm, preferably 10 mm to 15 mm, and is set to about 15 mm, which is the width of a typical user's index finger or more. By forming the cut portion 330 as a cross-shaped cut in this manner, the reliability of holding the sheet in the cut portion 330 can be further increased.
The diameter of the first circular part 332 is formed to be 2.5 mm to 4.0 mm, and by providing the first circular part in this way, the width that the take-out part 3 grips after taking out the sheet can be lengthened. Can be done. Further, by providing the second circular portion, the sheet can be taken out with less force.

Although FIG. 5 illustrates and describes the case where the extraction hole 33 is formed in a cross shape, the shape of the extraction hole 33 is not limited to this, and may be any shape as long as it can fulfill the above function. can be selected. That is, radial cuts may be formed by three or more linear cuts. Further, the extraction hole 33 may be formed by a single linear cut, or may have a circular shape, an elliptical shape, a substantially star shape, or the like.

(chamfered part)
The chamfered portion 34 is a region where a corner formed by the lower surface 3b of the extraction portion 3 and the hole wall 33a of the extraction hole 33 is chamfered, as shown in FIGS. 5 and 6.
Specifically, the chamfered portion 34 is a flat chamfered portion in which the edge of the hole wall 33a of the extraction hole 33 is chamfered with an inclined plane on the lower surface 3b of the extraction portion 3. 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 extraction hole 33 in the XY plane direction from the hole wall 33a of the extraction 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 a range of 0.5 mm to 1.0 mm.

Here, the case where the chamfered part 34 is formed by chamfering a plane has been illustrated and explained. However, as shown in FIG. The corner formed by the hole wall 33a may be chamfered to form a convex curved surface.

The above-mentioned take-out part 3 must be able to be inserted into the hole 21d, and must not come off from the lid main body 21 when the sanitary tissue paper storage container 100 is used. Since it is necessary to be able to push in the material, it must be made of a material with a certain degree of elasticity. Specifically, it is desirable that the hardness is 50 to 70, and specifically, for example, styrene-butadiene-based, polyester-based, polyethylene-based, urethane-based elastomers, etc. can be used, and the hardness is formed by injection molding. Ru. Note that the above hardness was measured according to JIS K 6253 (Type A durometer).

Further, when coloring the extraction portion 3, for example, a resin such as PE (polyethylene) mixed with an arbitrary pigment is mixed with the elastomer (pigment addition step). At this time, by changing the mixing ratio of the elastomer and PE, which is a resin, the performance of taking out the sheet by the taking out section 3 can be adjusted.
Here, the resin to be mixed with the elastomer may be one having higher hardness than the elastomer.

In addition, if the force required to pull out the sheet in the take-out section 3 is measured five 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 The value of is preferably within the range of 5N to 12N, more preferably 6N to 10N.
In addition, when a single roll of sanitary tissue paper P (for example, 80 sheets in a row with 79 perforations) is pulled out, the perforations do not cut and the following The permissible range of the number of consecutive sheets (number of times in a row) is 10 times or less, preferably 7 times or less.

(Effects of this embodiment)
In this embodiment, for example, as shown in FIG. 3, the height of the inner part 122 including the center of the bottom surface of the container body 1 is higher than the outer part 121 of the container body, which the outer edge of the sanitary tissue paper P comes into contact with. A placing part 12 formed to have a low height is provided on the container body 1, and by placing the roll-shaped sanitary tissue paper P on the placing part 12, the upper part of the roll is moved from the side to the center. You will receive the force that moves towards you.
In such a container body 1, when the sanitary tissue paper P is taken out and used in order from the core side, the shape retention force of the sanitary tissue paper P decreases as the inner diameter of the roll increases, so as shown in FIG. The upper part bends toward the center and approaches the take-out hole 33 provided approximately in the center of the top surface of the container body 1.
In this way, even when the amount of sheets decreases, the upper part of the roll continues to be located near the take-out hole 33, making it easier for the take-out part 3 to hold the end of the sanitary tissue paper P and prevent it from falling into the container body 1. It becomes difficult.

[Modified example]
Although the present invention has been specifically explained based on the embodiments above, 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 placement part 12 is not limited to a shape that is inclined toward the center of the bottom part, and there is a difference in height between the outer part 121 and the inner part 122 of the container body 1. The shape of the container body may be such that the upper part of the rolled sanitary tissue paper P placed on the placing part 12 receives force from the side toward the center, for example, as shown in FIG. 10. It may be shaped like a substantially inverted truncated cone cut out from the bottom part, which slopes downward from the outer part 121 to the inner part 122 of 1.
By doing so, the amount of members required to form the mounting portion 12 can be reduced .

Further, the shape of the sanitary thin paper storage container 100 does not necessarily have to be cylindrical, and may be formed, for example, in a prismatic shape that is pentagonal, hexagonal, etc. in plan view.
Moreover, the take-out part 3 may be detachably attached to the lid body 2 or may be fixed.
Further, the sanitary thin paper P may be a wet sheet impregnated with a chemical solution or a dry sheet.
