Description

The present invention relates to a paper storage box for storing a paper wiper.

A paper storage box that stores a laminated body of paper sheets such as a paper wiper, a paper towel, and a paper towel folded in a V-fold or a W-fold and can be taken out in a pop-up manner is widely known.

Of these paper sheets, especially in the paper storage box for storing a relatively thick and highly rigid paper wiper, it is necessary to pay sufficient attention to the shape of the outlet for taking out the paper wiper. This is because a highly rigid paper wiper has a large frictional resistance with the periphery of the outlet, and this frictional resistance causes the generation and tearing of paper dust. This frictional resistance is particularly noticeable between the widthwise edge of the paper wiper and the lateral inner periphery of the outlet.

In order to reduce the resistance between the edge of the paper wiper in the width direction and the inner periphery in the lateral direction of the outlet, a slit having a predetermined width as an outlet formed on the top surface of the storage box is provided on the top surface. A fiber laminate storage box extending along the longitudinal direction to both side surfaces is disclosed (see, for example, Patent Document 1).
According to the fiber laminate storage box described in Patent Document 1, a slit formed on the top surface of the storage box as an outlet extends to both side surfaces along the longitudinal direction of the top surface, and thus is a paper wiper. The resistance between the edge in the width direction and the inner periphery in the lateral direction of the outlet can be reduced, the generation of paper dust when removing the paper wiper from the fiber laminate storage box can be suppressed, and tearing can be prevented. Can be done.

As a paper wiper that is stored in a paper storage box and taken out in a pop-up manner, for example, there is a paper wiper having a width of 300 mm or more. Even if such a wide paper wiper has rigidity, the paper wiper is easily deformed due to the wide width. Therefore, when a wide-width paper wiper is stored in the fiber laminate storage box described in Patent Document 1, when the remaining amount of the paper wiper is low, the upper portion comes out from the outlet and the paper wiper is taken out next. Deforms, the resistance between the widthwise edge of the paper wiper and the lateral inner periphery of the outlet is reduced, the force to hold the paper wiper at the outlet is lost, and the paper wiper is inside the fiber laminate storage box. Problems such as falling into the paper, so-called dropback, will occur.

Further, in the fiber laminate storage box described in Patent Document 1, since the slits formed on the top surface of the storage box as outlets extend along the longitudinal direction of the top surface to both side surfaces. As a result, the outlet becomes wider, which may cause problems such as foreign matter being mixed in and a decrease in the rigidity of the storage box itself, resulting in a decrease in usability.
The solution to these problems is to improve the outlet on the top of the paper storage box, but it is not always satisfactory.

In view of the above problems, the present inventor of the present invention is a paper that stores a paper wiper that stores a laminate of paper wipers having a basis weight of 25 g / m2 to 35 / m2 and a width of 300 mm or more, which is widely used as a paper wiper.

It is an example of the embodiment of the paper storage box which concerns on this invention, and is the top view which shows the top surface which opened the outlet formed by the perforation. It is a top view which shows a part of the paper wiper which is stored in the paper storage box which concerns on this invention. (A) and (B) are explanatory views showing another example of the outlet shown in FIG. 1, respectively. FIG. 1 is a plan view showing the top surface of the paper storage box shown in FIG. 1 before opening the outlet whose outer shape is formed by perforations.

Hereinafter, an example of a mode for carrying out the paper storage box according to the present invention will be described in detail with reference to the drawings.
1 to 4 show an example of an embodiment of the paper storage box according to the present invention, and FIG. 1 shows the paper storage box of the present example in which an outlet formed by perforations is opened. A plan view showing the top surface of the paper, FIG. 2 is a plan view showing a part of the paper wiper housed in the paper storage box according to the present invention, and FIGS. 3 (A) and 3 (B) are taken as shown in FIG. An explanatory view showing another example of the outlet, FIG. 4 is a plan view showing the top surface of the paper storage box shown in FIG. 1 before opening the outlet formed by the perforations.

The paper storage box of this example stores a laminated body of paper wipers 10, and has an outlet 3 on the top surface 2 of the box body 1 formed in a rectangular parallelepiped so that the paper wipers 10 can be popped out. ..

The paper wiper 10 stored in the box body 1 has a basis weight of 25 g / m2 to 35 g / m2 and a width of 300 mm or more, and is V-folded or W-folded and laminated so that it can be taken out in a pop-up manner. ing.

The outlet 3 on the top surface 2 of the box body 1 for accommodating the laminated body of the paper wipers 10 is located substantially in the center of the top surface 2 and is formed horizontally in the width direction of the top surface 2. In this example, the center of the outlet 3 is the center of the top surface 2.
The horizontally long width W1 of the outlet 3 is 78.0% to 83.0%, preferably 80.5% to 81.5%, of the width W2 of the paper wiper 10.

By setting the width W1 of the outlet 3 to 78.0% to 83.0% of the width W2 of the paper wiper 10, the edge of the paper wiper 10 in the width direction when the paper wiper 10 is taken out from the outlet 3 It is possible to suppress the generation of paper dust due to the resistance of the outlet 3 to the inner periphery in the width direction, and to make it easier to take out the paper wiper 10 and prevent dropback.

When the width W1 of the outlet 3 is less than 78.0% of the width W2 of the paper wiper 10, the resistance between the edge of the paper wiper 10 in the width direction and the inner periphery of the outlet 3 in the width direction is large, and the outlet Not only is a large amount of paper dust generated when the paper wiper 10 is taken out from No. 3, but the paper wiper 10 may be torn if it is pulled out strongly.
Further, when the width W1 of the outlet 3 exceeds 83.0% of the width W2 of the paper wiper 10, the resistance between the edge of the paper wiper 10 in the width direction and the inner periphery of the outlet 3 in the width direction is small, and the take-out port 3 is removed. The force for holding the paper wiper 10 at the outlet 3 is lost, and the paper wiper 10 may fall into the box body 1.

Further, in this example, the outlet 3 is formed linearly in the width direction. The vertical width W3 of the straight portion 3a of the outlet 3 is 10.0% to 14.0%, preferably 12.4% of the vertical width W4 of the top surface 2 of the box body 1.

By setting the vertical width W3 of the straight portion 3a to 10.0% to 14.0% of the vertical width W4 of the top surface 2 of the box body 1, the upper portion is exposed from the outlet 3 and the paper wiper 10 to be taken out next is taken out. An appropriate resistance can be given between the paper surface of the paper wiper and the inner periphery of the take-out port 3 in the vertical width direction, and the dropback of the paper wiper 10 can be prevented more effectively.

If the vertical width W3 of the straight portion 3a is less than 10.0% of the vertical width W4 of the top surface 2 of the box body 1, the paper surface and the outlet 3 of the paper wiper 10 are taken out from the outlet 3. The resistance between the inside and the periphery in the vertical width direction of the paper wiper increases, which may make it difficult to take out the paper wiper 10, and if it exceeds 14.0%, the upper part comes out from the take-out port 3. The resistance between the paper surface of the paper wiper 10 taken out and the inner periphery of the outlet 3 in the vertical width direction becomes small, and the force to hold the paper wiper 10 in the outlet 3 is lost, so that the paper wiper 10 becomes the box body 1 It may fall inward.

Further, in this example, the wide portion 3b is formed in the center of the straight portion 3a of the outlet 3 in the lateral width direction, and the center of the wide portion 3b is at the center of the outlet 3, that is, the center of the top surface 2. And, the vertical width of the wide portion 3b is the maximum in the central portion. The maximum vertical width W5 of the wide portion 3b is 35.0% to 39.0%, preferably 37.1% of the vertical width W4 of the top surface 2 of the box body 1.

By setting the maximum vertical width W5 of the wide portion 3b to 35.0% to 39.0% of the vertical width W4 of the top surface 2 of the box body 1, the wide width is obtained when the first paper wiper 10 is taken out from the outlet 3. The paper wiper 10 can be easily picked from the portion 3b.

If the maximum vertical width W5 of the wide portion 3b is less than 35.0% of the vertical width W4 of the top surface 2 of the box body 1, when the paper wiper 10 is taken out from the outlet 3, the paper wiper 10 is removed from the wide portion 3b. It becomes difficult to pick easily, and if it exceeds 39.0%, the outlet 3 becomes wide, and the usability may be deteriorated due to the inclusion of foreign matter or the decrease in rigidity of the box body 1.

Further, the ratio of the lengths L1 and L2 of the straight portion 3a in the outlet 3 in the lateral width direction is 68.0% to 72.0%, preferably 70.8% of the width W1 of the outlet 3.

The wide portion 3b exists by setting the ratio of the lengths L1 and L2 of the straight portion 3a in the outlet 3 in the width direction to 68.0% to 72.0% of the width W1 of the outlet 3. The upper side of the paper wiper 10 is projected from the outlet 3, and the straight portion 3a suppresses the deformation of the paper wiper 10 to be taken out next, so that the paper wiper 10 can be easily taken out and the dropback can be prevented more effectively.

If the proportion of the lengths L1 and L2 of the straight portion 3a in the outlet 3 in the lateral width direction is less than 68.0% of the lateral width W1 of the outlet 3, the proportion of the wide portion 3b increases accordingly, and as a result. , There is a possibility that problems such as foreign matter being mixed in and a decrease in usability due to a decrease in the rigidity of the box body 1 may occur. If it exceeds 72.0%, the proportion of the wide portion 3b becomes smaller by that amount, and as a result, the outlet 3 When the first paper wiper 10 is taken out from the wide portion 3b, it may be difficult to easily pick the paper wiper 10 from the wide portion 3b.

In this example, the wide portion 3b provided in the outlet 3 is formed in a gentle arc shape in which the upper side and the lower side bulge outward, but the paper storage box of this example stores the laminated body of the paper wipers 10. However, the top surface 2 of the box body 1 formed in a rectangular parallelepiped has an outlet 3 on which the paper wiper 10 can be taken out in a pop-up manner. The shape of the outlet 3 is not limited to this, and may be, for example, a triangular shape as shown in FIG. 3 (A) or a trapezoidal shape as shown in FIG. 3 (B). May be good.

In this example, the outlet 3 provided on the top surface 2 of the box body 1 has an outer diameter formed by the perforations 4 on the top surface 2, and the portion surrounded by the perforations 4 is cut off to open the outlet 3. It has become.
FIG. 4 is a plan view showing the top surface 2 before opening the outlet 3 whose outer shape is formed by the perforation 4.

In this example, a slit 5 is formed in the central portion of the portion to be the wide portion 3b of the outlet 3 in the vertical width direction in the portion surrounded by the perforation 4, and the portion surrounded by the perforation 4 is formed. It can be separated into left and right parts from the slit 5.
Further, in the perforation 4, although not shown, it is preferable that the horizontal width direction is a double line and the vertical width direction is a single line. Further, it is preferable that the perforation 4 to be a double line has a structure in which the cut portion of one perforation and the cut portion of the other perforation are arranged in a staggered pattern.
