[0002]
[Prior art]
2. Description of the Related Art Conventionally, a storage box for storing sanitary thin paper such as tissue paper in a bundle has been used so that a thin paper can be pulled out one by one from an outlet on the upper surface of the box.
A perspective view of this storage box is shown in FIG. 13, and the appearance thereof is a rectangular parallelepiped shape, while the upper surface 1 a is formed with a perforation for forming the outlet 3. A cut piece (not shown) is cut along the perforations to open the outlet 3.
[0003]
The outlet 3 is covered with a film 11 from the inside of the storage box 1, thereby preventing dust and dirt from entering the box 1 and keeping the tissue paper 21 inside hygienic. Further, the film 11 is formed with a linear slit 13 positioned at the center line of the outlet 3, and the tissue paper 21 in the box can be taken out one by one through the slit 13. Yes. On the other hand, the slit 13 of the film also serves to prevent the web from dropping.
[0004]
The tissue paper 21 is usually used by appropriately taking out a set of two rectangular sheets (also referred to as two plies) as a set and taking out the set as a set. On the other hand, in the storage box 1, as shown in the longitudinal sectional view of the storage box 1 in FIG. 14, this set of tissue papers 21 is folded in two and a large number of sets are bundled in the vertical direction. It is stacked and stored. A part 21 a of the upper half of the tissue paper 21 on the uppermost surface of the tissue paper bundle 23 is held while going out through the slit 13, and is pulled out further upward so that the uppermost surface of the uppermost tissue paper 21 is pulled out. The tissue paper 21 is pulled out. On the other hand, at this time, the portion 21b other than the portion 21a of the tissue paper 21 is in contact with the upper half of the next tissue paper 21 until the upper half is held in the slit 13 from the storage box 1. It comes to pull out.
[0005]
As a stacking method in which the next tissue paper 21 can be pulled out to the slit 13 holding position in this way, for example, the method shown in FIG. That is, while sandwiching both the lower half of the upper set of tissue papers 21 and the upper half of the lower set of tissue papers 21, the set of tissue papers 21 located between them is folded in half. This may be repeated in the height direction and the tissue papers 21 may be stacked in a bundle.
[0006]
[Problems to be solved by the invention]
By the way, recently, especially in the tissue paper 21, in order to improve its portability, a reduction in the size of the storage box 1 has been achieved by reducing the height of the storage box 1 without reducing the number of storage groups.
However, when the tissue paper bundle 23 is too bulky compared to the height of the storage box 1, the tissue paper bundle 23 is pressed into the box by being compressed by the box upper surface 1a and the bottom surface 1b. . For this reason, the topmost tissue paper 21 in the state of being pulled out is strongly pressed against the back side 1c of the box upper surface 1a. If the tissue paper 21 is forcibly pulled out from the slit 13 in this state, especially in the beginning of use. There is a risk of tearing the tissue paper 21.
[0007]
The present invention has been made in view of such conventional problems. Even when the bulk of the sanitary thin paper bundle stored in the box is too high compared to the box height, the thin paper is not torn. It aims at providing the sanitary thin paper storage box which can be taken out smoothly.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment according to the present invention will be described in detail with reference to the accompanying drawings.
FIG. 1 is a perspective view showing a sanitary thin paper storage box according to the present embodiment, FIG. 2 is a longitudinal sectional view thereof, and FIG. 3 is a rear view of the upper surface of the box. 4 to 6 are rear views of the upper surface of the box according to the modification of the present embodiment. In addition, in each back view over FIGS. 3-6, while showing the sticking area | region of a postscript film mainly in a figure (a), a postscript flexible area | region is mainly shown in FIG. (B). Moreover, in this embodiment, although the case where a thin paper is a tissue paper is illustrated, it will not be restricted to this as long as the folded thin paper can be pulled out sequentially, and it cannot be overemphasized that it is applicable also to a kitchen paper etc.
[0018]
The sanitary thin paper storage box 1 according to the present embodiment is a rectangular parallelepiped paper box as shown in FIG. Typical dimensions in the case of the compact type are 240 to 247 mm in the longitudinal direction, 115 to 117 mm in the lateral direction, and 50 to 65 mm in the height direction. The tissue paper bundle 23 stored in the box is usually formed by folding two 229 × 197 mm two-ply rectangular tissue papers into two, and stacking 200 sets in the height direction in the manner described above. Is done. However, you may change the said dimension and the number of accommodation groups suitably.
[0019]
Further, a perforation is set for the outlet 3 on the upper surface 1 a of the storage box 1, while the outlet 3 is covered with a film 11. If the outlet 3 is cut and opened along the cut line, the tissue paper 21 can be sequentially pulled out one by one through the slit 13 of the film 11.
[0020]
As shown in the rear view of the upper surface of the box in FIG. 3A, the outlet 3 is formed in a rectangular shape elongated in the longitudinal direction at the center of the box upper surface 1a, and its four corners are chamfered into quadrants. ing. The film 11 has a rectangular shape larger than the dimension of the outlet 3, and the slit 13 is formed in a straight line at the center thereof. And this film 11 is stuck by the adhesive on the back side 1c of the box upper surface 1a, positioning the slit 13 on the centerline of the said outlet 3. FIG. The sticking area 11a is basically set in an annular shape along the outlet 3. Further, the length of the slit 13 is 55 to 90% of the length of the tissue paper 21 in the longitudinal direction so as to improve the retention of the tissue paper 21 while suppressing the tearing at the slit ends 13a and 13b. preferable.
[0021]
Here, in the present invention, as shown in FIGS. 1 and 3, the peripheral portion of the outlet 3 on the box upper surface 1 a is the edge of the opening line of the outlet 3 formed by cutting a perforation. the originating 5a, it is configured that the cutting line 5 of the slit-shaped. Specifically, in the illustrated example, a pair of cutting lines 5 starting from two opposite corners of the outlet 3 are set linearly in the direction toward the corner of the adjacent box upper surface 1a. (Structure of claim 1) .
[0022]
Therefore, before using the tissue paper 21, the peripheral portion along the slit-shaped cut line 5 is divided into the door-shaped, vertical flexibility is imparted to the peripheral portion. Therefore, as shown in FIG. 2, when pulling the tissue paper 21 upward by pulling the tissue paper portion 21 a held upright in the slit 13, an upward pulling force is applied to the surrounding portion via the slit 13. However, due to the pulling force, the peripheral portion can be easily bent upward. Therefore, at the moment of pulling out, the pressing force against the box upper surface back side 1c acting on the uppermost tissue paper 21 can be alleviated and can be smoothly taken out from the slit 13 without tearing the tissue paper even at the beginning of use. it can.
Since the cutting line 5 is completely divided in advance in the form of a slit, the user does not have to perform a cutting operation, and the convenience to the user is improved.
[0023]
Further, as shown in FIG. 3 (b), a region 3d (double line in the figure) of the outlet 3 is added to a flexible region 1d (shaded portion in the figure) to which flexibility is given by the cutting line 5. It is desirable that the total area of the flexible region including the hatched portion occupies 25% or more, more preferably 35% or more with respect to the area of the box upper surface 1a (configuration of claim 2).
[0024]
And if the area ratio of the whole flexible area | region with respect to the area of the box upper surface 1a shall be 25% or more, the surrounding part of the said outlet 3 will bend upwards to such an extent that the said pressing force can be reduced effectively. Can do.
A ruled line may be drawn along the bending start line 1e of the flexible region 1d so that the flexible region 1d formed by the cutting line 5 is bent reliably.
[0025]
Moreover, as illustrated in FIG. 3, it is desirable that the cutting lines 5 are set in pairs so as to be point-symmetric with respect to the plane center 3a of the outlet 3 (configuration of claim 3).
And if it does in this way, the pressing force distribution of the said surrounding part can be made point-symmetric with respect to the extraction port 3. FIG. Therefore, the tissue paper 21 is not pulled out by inclination due to the asymmetry of the pressing force distribution and is not caught at the slit ends 13a and 13b, and can be pulled out smoothly. Further, it is possible to prevent the upper end edge of the next tissue paper 21 held in the slit 13 in association with the drawer from being inclined from the horizontal, and to improve the appearance of the held tissue paper 21a. .
[0026]
As shown in FIG. 4, if the cutting lines 5 are provided at the four corners, that is, the pair of cutting lines 5 shown in FIG. 3 is set in pairs so as to be further symmetrical with respect to the center line of the outlet 3. By doing so (configuration of claim 4), it becomes possible to make the distribution of the pressing force around the outlet 3 more uniform in the circumferential direction, and the tissue paper 21 can be pulled out more smoothly.
[0027]
The cutting line 5 may be a wave curve as shown in FIG. 5, but is preferably a straight line as shown in FIG. 3 (configuration of claim 5).
[0028]
The effective length of the cutting line 5, that is, the maximum value of the straight line distance from the starting point 5a of the cutting line 5 to the point on the cutting line 5 is preferably 10 mm or more (configuration of claim 6), More preferably, it is 20 mm or more. Here, when the cutting line 5 is as shown in FIG. 6, the effective length is not the linear distance connecting the starting point 5 a and the ending point 5 b of the cutting line 5, but L in the figure as the maximum value.
If the effective length is 10 mm or more, the peripheral portion of the outlet 3 can be bent upward to such an extent that the pressing force can be effectively reduced. Increase.
[0029]
Further, the film 11 not only covers the outlet 3 but also sticks to the box upper surface 1a while extending and extending to a set area of the cutting line 5, as shown in FIG. A cutting line is not set on the film 11 (structure of claim 1) .
[0030]
In addition, in addition to the said cyclic | annular sticking area | region 11a around the outlet 3, the sticking area | region 11a of the said film 11 is further along the cutting line 5, as shown in FIG. Thus, the gap X1 with the cutting line 5 is set to 40 mm or less and is set around the periphery (structure of claim 1).
[0031]
Moreover, it is desirable that the elongation in the longitudinal direction of the film 11 is 50% or more (configuration of claim 7) .
[0032]
As the material of the film 11 having such elongation performance, polyethylene, polypropylene, polyester, and the like are preferable.
Although the elongation performance is somewhat inferior, a synthetic paper mixed with synthetic fiber or chemical fiber, or a sheet having a basis weight of 10 to 35 g / m ^{2 made} of a nonwoven fabric can be used. As the synthetic fiber and chemical fiber mixed with the synthetic paper, rayon, acetate, vinyl acetate and the like are preferable, and furthermore, recyclability is lacking, but 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 void nonwoven fabric, a melt blown nonwoven fabric, a spunbonded nonwoven fabric and the like can be used from the viewpoint of form. From the material side of the nonwoven fabric, polyethylene, polypropylene, polyester, pulp and the like are applicable.
The reason why the basis weight in the above range is preferable in the synthetic paper and the nonwoven fabric is that the strength is insufficient if it is less than 10 g / m ² , and the probability of tearing of the film 11 is increased when the tissue paper 21 is taken out, while 35 g / m ^2. This is because not only the cost is increased but also noise at the time of taking out may increase.
[0033]
Here, another aspect of the cutting line setting pattern will be described with reference to the rear view of the top surface of the box in FIG. Similarly to FIG. 3 to FIG. 6, whereas mainly showing the pasting Chakuiki 11a of the film 11 in FIG. 7 (a), mainly showing the flexible region 1d in FIG. 7 (b). In addition , the same components as those in the above-described embodiment are denoted by the same reference numerals, and redundant description is omitted.
FIG. 7 is obtained by adding a pair of cutting lines 5 on the extension line of the center line in the longitudinal direction of the outlet 3 to the setting pattern of the cutting lines 5 of FIG.
[0039]
As mentioned above, although embodiment which concerns on this invention was described, this invention is not limited to this embodiment, The deformation | transformation as shown below is possible in the range which does not deviate from the summary.
In this embodiment, although the substantially rectangular shape was illustrated as a shape of the outlet 3, it is not restricted to this , A rhombus and a hexagon may be sufficient.
[0040]
In the present embodiment, the shape of the outlet 3 is substantially rectangular, while the four corners thereof are chamfered in a quadrant. However, the present invention is not limited to this, and the short side of the outlet 3 is an arc shape such as a semicircular shape. Anyway.
[0041]
In the present embodiment, the rectangle is exemplified as the shape of the film 11, but the shape is not limited to this as long as the entire flexible region is completely covered, and may be a rhombus and a hexagon.
[0042]
