[Prior art]
The tissue paper is stored in a storage box called a carton having a slit-shaped outlet on the upper surface and is commercially available. Generally, tissue paper is a so-called two-ply state in which two pieces of tissue paper are stacked, and when a piece of tissue paper is taken out through a slit of a film attached to a window on the upper surface of the storage box, a part of the next piece of tissue paper is obtained. Are folded out in a so-called pop-up system so that they can be easily taken out next time by being exposed to the outside and stored in a storage box.
[0003]
By the way, the storage box used to have a height of 65 mm in the past, but it is inconvenient for storing and carrying at home. Are commercially available.

[0005]
[Problems to be solved by the invention]
However, since the compression ratio at the time of storage is increased, the pop-up function does not work properly especially when the first few sheets are taken out of the storage box, and the tissue paper often breaks. Further, when the paper thickness is excessively reduced, the user feels anxiety such as easily tearing when actually using the tissue paper, such as blowing his nose, and the hand or touch feeling is not sufficient.
[0006]
On the other hand, the compactness of the storage box in recent years can be said to be excessive beyond the convenience of the user, and in fact, the user of the tissue paper has improved the drawability rather than the compactness of the storage box.

[0022]
BEST MODE FOR CARRYING OUT THE INVENTION
Embodiments of the present invention will be described below in detail with reference to the drawings.
(Tissue paper)
The tissue paper of the present invention relates to a two-ply tissue sheet.
Tissue paper according to the present invention, the measured basis weight is 10~13g / ^{m 2,} based on a single JIS P 8124 of those with two-ply one set, preferably at 11.9~12.7g / ^{m 2} is there. If the rice tsubo is less than 10 g / m ² , papermaking becomes difficult. If it exceeds 13 g / m ² , the softness will be reduced, and the feeling of use and the drawability from the storage box will be reduced.
[0023]
On the other hand, the tissue paper having a pair in two-ply of the present invention, the thickness of the case at the steel sheet with a tissue paper single circular plane of compression the cross-sectional area 2 cm ^2, which in compressive load 50 gf / cm ² obtained by compressing the tissue paper The displacement difference (TM-TO) between TM and the thickness TO when compressed with a compression load of 0.5 gf / cm ² is 0.145 to 0.300 mm, and the thickness TM is 0.090 mm or more.
[0024]
The thickness displacement difference (TM-TO) was determined by using a “handy compression tester KES-G5” manufactured by Kato Tech Co., Ltd., laying tissue paper on a horizontal pedestal made of steel plate, and compressing the area approximately at the center. A steel plate having a circular plane of 2 cm ² is brought into contact, and the state of the contact is taken as a zero point. From the zero point, the steel plate having the circular plane is placed vertically downward at a compression load of 0.5 gf / cm ² and a speed of 10 mm / min. After compressing and measuring the thickness in a state where the indentation is stable, the compression load is further compressed at 50 gf / cm ² and a speed of 10 mm / min to measure the thickness in a state where the indentation is stable. Calculate the thickness difference from the measured value of The greater the displacement difference, the greater the depth of indentation when pushed up to 50 gf / cm ² , which indicates that the paper is soft and does not make the user feel the thinness of the paper.
[0025]
Further, the paper thickness of one set of two sheets is 90 to 120 μm, preferably 94 to 112 μm. When the paper thickness is thin, the paper thin feeling felt by the user becomes remarkable, and the water absorption is poor, and the function as a tissue paper is reduced. Furthermore, manufacturing is difficult from a cost and technical point of view. If the paper is excessively thick, the drawability when a predetermined number of sheets are stored in a storage box to form a product becomes poor.
[0026]
The paper thickness is measured using a paper thickness measuring machine “CI-10B” manufactured by Citizen Watch Co., Ltd. under the conditions of JIS P 8111 in accordance with the provisions of JIS P 8118. Specifically, make sure that there is no dust, dirt, etc. between the plunger and the measuring table, lower the plunger on the measuring table, move the gauge memory to zero, and then Raise the sample, place the sample (tissue paper) on the test bench, lower the plunger and read the gauge at that time. The measurement is an average value of 10 measurements.
[0027]
In addition, the tissue paper according to the present invention preferably has a range of tensile strength, water absorption, and whiteness specified in JIS S 3104.
[0028]
The tissue paper can be obtained by selecting various manufacturing conditions. By the way, for example, the compression characteristics include the mixing ratio of LBKP and NBKP as raw materials, the type of pulp (fiber roughness, or the type and age of tree as raw material), beating degree, papermaking moisture, calender gap, pressure, material, surface activity It can be adjusted by the addition of the agent and the amount thereof. The pulp desirably does not contain waste paper pulp.
[0029]
The softness / bending properties can be adjusted by tensile strength, aspect ratio, crepe shape (crepe ratio, crepe height difference, etc.), moisture content, density, addition of paper strength agent, addition of surfactant and its amount, etc. It is possible.
[0030]
The surface properties can be adjusted by pulp blending, calendering conditions, papermaking moisture, doctor blade angle, blade angle, balance of adhesion / peeling strength, crepe ratio, addition and amount of surfactant, and the like.
[0031]
(Articles containing tissue paper)
Next, an article containing the tissue paper according to the present invention will be described.
The tissue paper according to the present invention is particularly suitable for use in a storage box in which the outer dimension of the height of the storage box is 55.5 to 64.5 mm. In this case, it is preferable that the so-called two-ply tissue paper is folded and stored in a pop-up manner in accordance with a general storage method.
[0032]
It is desirable that the bulk density of the two sheets be less than 0.13 g / cm ³ (more preferably, 0.11 to 0.13 g / cm ³ ). The bulk density is defined as (measutsubo × tissue paper area × number of sets × 2) / volume in the storage box.
[0033]
Further, the ratio of (web bulk) / (JIS paper thickness × number of sets × 2) is 1.5 or less (more preferably 1.3 to 1.5), and (JIS paper thickness × number of sets × 2) / The ratio of (storage box height) is preferably 0.70 or less (more preferably, 0.55 to 0.70).
[0034]
In the present invention, the ratio of the slit length of the take-out opening to the sheet length in the long side direction of the upper surface of the storage box is 75 to 85%, and the ratio of the sheet width in the short side direction of the upper surface of the storage box to the sheet length. Is desirably 75 to 90%.
[0035]
As shown in FIGS. 1 and 2, the article containing the tissue paper according to the present embodiment is a so-called pop-up system in which a pair of tissue papers described in the above (Tissue Paper) section is paired. The number of sheets to be folded and stored in a predetermined storage box in one box specified in JIS S 3104, for example, 360 sets of 180 sets, or 386 sets of 188 sets in some cases (hereinafter referred to as Tissue paper products). Although 200 sets of 400 sheets can be adopted, they are inferior in takeout properties and are not so preferable.
[0036]
The pop-up folding is a well-known technique and will not be described in detail.
[0037]
On the other hand, in such tissue paper products, the outer dimension of the height of the storage box is set to 55.5 to 64.5 mm, which is lower than 65 mm, which was once lacking in portability and storage properties, and is currently in the mainstream take-out property. And higher than 50 mm where the paper thinness is reduced. By setting the height in such a range, it is possible to improve the feeling of thinness of the paper and the ease of taking out the paper without sacrificing the portability and the storability.
[0038]
Here, in the tissue paper product according to the present embodiment, when the outer dimension of the height of the storage box is set as described above, the shape of the takeout opening is devised so that the tissue paper can be taken out properly. . That is, the sheet 2 having the slit 2A serving as an opening covers the window 1A formed on the upper surface of the storage box 1 from the inside, and the tissue paper inside is taken out through the slit 2A sequentially. Here, the window 1 </ b> A may have a known configuration in which a notch such as a perforation is previously formed on the upper surface of the box 1, and a portion surrounded by the notch is peeled off.
[0039]
The sheet 2 is larger than the size of the window 1A, for example, is rectangular as shown in the figure, and is adhered to the upper surface of the box from the inside with an adhesive. Further, in the present embodiment, a polyethylene film sheet is used as the sheet 2, but instead, a synthetic paper having a basis weight of 10 to 35 g / m ² and a mixture of synthetic fibers or chemical fibers, or A sheet made of a nonwoven fabric can also be used. 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 in terms of form. Examples of the material include polyethylene, polypropylene, polyester, and pulp. When the grammage 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 , there is no problem of strength, but not only the cost is increased, but also noise at the time of taking out tends to increase.
[0040]
The sheet 2 is provided with a slit 2A. When the sheet 2 is bonded to the inside of the upper surface of the box 1, the slit 2A is formed at the center of the window 1A in the width direction (in the longitudinal direction of the box 1 (tissue paper 3). The length of the slit 2A is desirably shorter than the entire length of the window 1A in the longitudinal direction, as shown in FIG. 1), the length of the window 1A may be the same as the total length in the longitudinal direction, and further, as shown in FIG. It can be longer than the entire length in the longitudinal direction.
[0041]
The slit is usually formed in the form shown in FIG. 1A, and the slit length is desirably 175 mm to 185 mm. As described above, the length L of the slit 2A is 75 to 85% of the length of the sheet in the long side direction of the upper surface of the storage box from the viewpoint of preventing breakage in consideration of the characteristics of the tissue paper, In particular, it is desirable to be 76 to 85%.
[0042]
On the other hand, in the tissue paper product according to the present embodiment, the value of the density in the height direction expressed by (outside dimension of height of storage box) / (total area of tissue paper) is 2.90 to 5.60 mm / it is m ^2, and preferably a 3.40~4.00mm / ^{m 2.} As described above, by setting the value of the density in the height direction to the above value, the take-out property becomes excellent.
[0043]
Here, the size of the tissue paper referred to in the present invention is synonymous with the size of one piece of tissue paper (the area represented by (length) × (width) of the tissue paper) according to JIS S 3104. The numerical value is not limited to the range specified in JIS S 3104. Of course, it may be within the range of the size of one sheet of paper specified in JIS S 3104, and it is preferable that the range be within this range. A particularly suitable size is 450 cm ² , about 197 mm in length and about 229 mm in width.
[0044]
In the present invention, since the size of the tissue paper is arbitrary, the size other than the height of the storage box, that is, the length and the width are also arbitrary, but the general commercial form, storage, and portability can be improved. With consideration, the preferred length of the storage box is 240 ± 25 mm and the width is 115 ± 25 mm.
[0045]
Here, the drawability of the tissue paper will be described in detail. As shown in FIG. 2, when taking out the tissue paper 3 from the storage box 1, the tissue paper 3 is pulled up with the knob 3T at the center near the side edge of the tissue paper 3. . At this time, the lateral ends of the tissue paper gradually gather at both ends 2a and 2b of the slit 2A as the tissue paper is pulled up. Since the collected tissue paper 3 is pulled up while being hooked on both ends 2a and 2b of the slit 2A, the grip portion 3T and both ends 2a and 2b of the slit 2A are moved with respect to the tissue paper currently being pulled up. Tensile forces F, F act intensively on the connecting part. In particular, in the latter half of the take-out operation, a force for pulling up the subsequent tissue paper by folding is also required, and the corresponding tensile force is added. Supplementary explanation of the tensile force F acting on the tissue paper is as follows. In the first half at the time of taking out, X (the force for collecting the lateral ends of the tissue paper at both ends 2a and 2b of the slit 2A: the frictional force with the subsequent tissue paper) + Y (a force that pulls up against the frictional force between the tissue paper 3 and both ends 2a and 2b of the slit 2A). In the latter half, Z (folding) is almost performed with respect to X + Y. The force for lifting the subsequent tissue paper is also added by stacking. In the tissue paper, the tensile force F connecting the knob 3T and both ends 2a and 2b of the slit 2A acts as a breaking force in the direction in which the tissue paper 3 is pulled out. Therefore, in the conventional product, the paper was thin and the compression ratio at the time of storage was high, so that the paper was easily broken at the time of drawing. However, in the tissue paper product according to the present invention, the tissue paper 3 did not break.
[0046]
(Method of manufacturing tissue paper and articles containing tissue paper)
The tissue paper and the tissue paper product according to the present embodiment can be manufactured by known equipment and ordinary methods. That is, the raw material pulp can be manufactured by papermaking with a paper machine, creping, calendering, folding in a pop-up manner with an inter holder, cutting into a predetermined size, and storing in a storage box.
[0047]
The details of each treatment are as follows. In the papermaking step, the raw pulp and the papermaking conditions are adjusted so as to fall within the range of the rice tsubo of the present invention. At this time, the beating width of the raw pulp is reduced to increase the density. When the density is defined by defining the rice tsubo as described above, the paper strength is increased, but the paper thickness and the softness are reduced.
[0048]
Therefore, in the creping step, the creping rate is set to a high value so that the displacement difference in thickness, which is an index of the softness and the sense of thickness, falls within the range of the present invention. The crepe rate can be increased by adjusting the edge angle of the crepe.
[0049]
(Equation 1)

[0050]
In the calendering step, the calendering is performed by adjusting the pressure in each of the calendering processes of the online machine calendar and the ply machine calendar so that the paper thickness is excessively reduced and does not fall out of the range of the paper thickness of the present invention. By ply machine calendering, the papermaking base papers are piled into one set.
[0051]
In this way, tissue paper base paper is manufactured. Then, this tissue paper base paper is alternately folded by an inter holder so as to be a pop-up system later. At this time, the pull conveyor pressure of the inter holder is adjusted in consideration of the size, particularly the height of the storage box and the size of the tissue paper after cutting. Thereafter, the tissue paper product is cut into a predetermined size and stored in a storage box to manufacture the tissue paper product of the present invention.
[0052]
The raw pulp is preferably made of 100% wood pulp. In this case, the ratio of NBKP: LBKP is 10:90 to 70:30, preferably 50:50 to 93: 7, and particularly preferably 65:35 to 69:31. The higher the proportion of NBKP, the more flexibility can be obtained, which is preferable.
[0053]
【Example】
The properties of a commercially available product, an old product that had been marketed until about one year ago, and the product according to the present invention were investigated. The results are shown in Tables 1 and 2.
[0054]
[Table 1]
