And, these sanitary papers, if it is tissue paper, generally a sheet having a slit covers a window formed on the upper surface of the box from the inside, and the internal sanitary thin paper is sequentially taken out through the slit. It is stored in a storage box. The sanitary thin paper accommodated in this manner is required to have good touch, soft touch, and not to be broken at the time of taking out, and to have sufficient strength to withstand use.

Examples of the sanitary thin paper according to the present invention include tissue paper, toilet paper, and dust paper. Hereinafter, the case where the tissue paper is used will be described. In addition, as for the vertical direction and the horizontal direction of the tissue paper, the flow direction of the papermaking is the vertical direction, and the perpendicular direction is the horizontal direction. That is, at the stage of storage in the box, the longitudinal direction of the box is the horizontal direction, and the short direction is the vertical direction. In the following embodiment, the case of two sheets (two plies) will be described, but a single sheet (one ply) is also possible. As the number of sheets to be stacked, 200 sets of two sheets (two plies) are preferable, and a total of 400 sheets is suitable. Therefore, the following description is based on this case.

ある。Generally, the tensile strength is higher in the longitudinal direction than in the transverse direction. However, in order to prevent the tissue paper from being broken when it is taken out of the storage box with a wet hand, the tensile strength in the horizontal direction when dry and the tensile strength in the vertical direction when wet are 32 N / m or more. / M or more is important.

を得ることができる。On the other hand, the tensile strength in the longitudinal direction when dried is 2.5 to 3.5 times, preferably 2.8 times the tensile strength in the transverse direction when dried.
It is preferable to set it to 3.4 times. Increasing the tensile strength in the longitudinal direction during drying increases the strength but reduces the flexibility. When the tensile strength in the longitudinal direction is reduced, the flexibility is improved but the strength is inferior. Conventionally, the ratio was more than 3.5 times the mainstream, but according to the present invention, the tensile strength in the vertical direction during drying was suppressed, and instead, the tensile strength in the horizontal direction during drying was reduced. By adjusting to increase, good touch,
A material which gives a soft touch and has sufficient strength can be obtained.

As shown in FIG. 1, a preferred storage box for tissue paper according to the present invention includes a window 1A formed on the upper surface of the box 1 and a slit 2A.
This is a storage box in which a sheet 2 having an inner surface is covered from the inside, and the internal tissue paper is sequentially taken out through the slit 2A. Here, the window 1A may have a known configuration in which a cutout such as a perforation is formed in advance on the upper surface of the box 1, and a portion surrounded by the cutout is peeled off.

For example, as shown in the figure, it is formed in a rectangular shape, and is adhered to the upper surface of the box from the inside with an adhesive. In the present embodiment, sheet 2
Although a polyethylene film sheet was used as an example, a sheet made of synthetic paper having a basis weight of 10 to 35 g / m 2 and mixed with synthetic fibers or chemical fibers, or a nonwoven fabric sheet may be used instead. As synthetic fibers or chemical fibers, rayon, acetate and vinyl acetate are suitable, and if recycling is neglected to some extent, polyethylene, polypropylene, polyester and the like can also be used. On the other hand, as the nonwoven fabric, an air-through nonwoven fabric, a point-bonded nonwoven fabric, a melt-blown nonwoven fabric, a spun-bonded nonwoven fabric, or the like can be used from the aspect of the form. Examples of the material include polyethylene, polypropylene, polyester, and pulp. The grammage is
If it is less than 10 g / m 2 , the strength is insufficient, and the probability of tearing or breaking when taking out the tissue paper 3 increases. Conversely, if it exceeds 35 g / m 2 , although there is no problem of strength, not only the cost is increased, but also noise at the time of taking out tends to increase.
