  DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments for carrying out the present invention will be described in detail with reference to the accompanying drawings. Throughout the description of the embodiment of the present invention, the same reference numerals are given to the same elements.

<Box carton>
As shown in FIGS. 2 to 7, the box-type carton 1 is a rectangular parallelepiped or cubic box that houses a sheet-like paper wiper laminate. Further, as shown in FIGS. 1 and 3 to 7, the box-type carton 1 is attached to an outlet 10 having an outer periphery formed by perforations and a back surface outside the outlet 10, and a slit 21 for taking out. And a window pasting film 20 having a top surface portion. When the paper wiper stored in the box-type carton 1 is used, as shown in FIG. 3, the cut piece 11 formed from the portion surrounded by the perforation is cut off and then stored in the box-type carton 1. In this case, the paper wiper passes through the slit 21 of the window pasting film 20. The box carton 1 of the present invention is made of paper except for the window pasting film 20, and wood pulp such as softwood bleached kraft pulp (NBKP) or hardwood bleached kraft pulp (LBKP) or newspaper as a base material. Used paper pulp from magazines and magazines can be used.

  Since the paper wipers stored in the box-type carton 1 of the present invention can be taken out in a pop-up manner, the individual paper wipers are stacked while sandwiching the upper and lower paper wipers by being Z-folded or V-folded. The slits 21 are arranged in a direction parallel to the unfolded sides of the paper wipers stacked in the box-type carton 1. Moreover, the paper wiper accommodated in the box-type carton 1 of the present invention is used for a wide range of applications such as cleaning work and product packaging.

  In the description of the present specification, the lateral direction of the box-type carton 1 is a direction parallel to the slit 21 and is a direction indicated by a symbol X in the drawing. The vertical direction of the box-type carton 1 is a direction orthogonal to the horizontal direction in a plan view, and is a direction indicated by a symbol Y in the figure. Further, the height H of the box-type carton 1 is a dimension along the stacking direction of the paper wipers housed inside.

  In the present invention, the size of the box-type carton 1 may be any size suitable for storing a general paper wiper. Specifically, the height H of the box-type carton 1 is 80 mm. The horizontal dimension of the box carton 1 is 80 mm or more and 150 mm or less, and the vertical dimension of the box carton 1 is 80 mm or more and 150 mm or less.

The box-type carton 1 has an outlet 10 whose outer periphery is formed by a perforation at the top surface portion of the box-type carton 1. The outlet 10 is located substantially at the center of the top surface portion of the box-type carton 1. When using the paper wiper stored in the box-type carton 1, as shown in FIG. 3, the cut piece 11 formed from the portion surrounded by the perforations is cut and used.

  The maximum horizontal dimension of the outlet 10 is 50% or more and 80% or less with respect to the horizontal dimension of the box-type carton 1, and the maximum vertical dimension of the outlet 10 is the vertical dimension of the box-type carton 1. It is 30% or more and 80% or less with respect to the dimension of a direction. For this reason, it becomes easy to confirm the paper wiper accommodated in the box-type carton 1 through the film 20 for window sticking, and the box-type carton 1 of this invention is excellent in visibility. Furthermore, from the viewpoint of improving the visibility, the maximum vertical dimension of the outlet 10 is preferably 40% or more and 80% or less with respect to the vertical dimension of the box-type carton 1. Further, by making the maximum vertical dimension of the outlet 10 in the above range, the amount of deformation of the window pasting film 20 when taking out the paper wiper is increased, the taking out becomes smooth, and the taking out property is improved. Further, when the paper wiper is taken out, so-called dropback that falls into the box-type carton 1 can be made difficult to occur.

  Examples of the shape of the outlet 10 include a rhombus as shown in FIG. 1, a substantially rectangular shape as shown in FIG. 4, a substantially elliptical shape as shown in FIG. 5, and a hexagon as shown in FIGS. 6 and 7. It is done. Here, when the paper wiper is taken out from the box-type carton 1, the frictional resistance applied to the paper wiper is concentrated at the center in the lateral direction of the slit 21, so that the shape of the outlet 10 is any diagonal line of the outlet 10. Is parallel to the slit 21 and the longitudinal dimension of the outlet 10 in the lateral center of the outlet 10 is 24 mm or more and 120 mm or less, or two opposite sides of the outlet 10 are The two opposite sides of the outlet 10 are parallel or perpendicular to the slit 21 and the vertical dimension of the outlet 10 at the lateral center of the outlet 10 is 24 mm or more and 120 mm or less. It is preferable that the shape is any one of hexagons. By making the shape of the outlet 10 into a rhombus or a hexagon as described above, when the paper wiper is taken out from the box-type carton 1, a window at the central portion in the lateral direction of the slit 21 where the frictional resistance is most easily applied to the paper wiper Since the film for pasting 20 is easily deformed, the frictional resistance applied to the paper wiper at the time of taking out can be reduced, generation of paper dust can be suppressed, and the takeout property of the paper wiper can be further improved.

[Film for window pasting]
As shown in FIGS. 1 and 3 to 7, the box-type carton 1 of the present invention has a window pasting film 20 affixed to the back surface outside the outlet 10 on the top surface portion of the box-type carton 1. The material for the window pasting film 20 may be a plastic such as polyethylene used for the general window pasting film 20. The window pasting film 20 has a slit 21 for taking out.

  In the box carton 1 of the present invention, the window pasting film 20 has a thickness of 20 μm or more and 60 μm or less. By setting the thickness of the window pasting film 20 within the above range, the frictional resistance between the paper wiper and the window pasting film 20 can be reduced, and the generation of paper dust can be suppressed. By providing rigidity, it is difficult to generate dropback.

  In the box-type carton 1, the length of the slit 21 of the window pasting film 20 is 60% or more and 80% or less with respect to the maximum horizontal dimension of the outlet 10. By adjusting the length of the slit 21 to the above range, it is possible to reduce the frictional resistance between the paper wipers when taking out and suppress the generation of paper dust.

  Moreover, in order to reduce the frictional resistance at the time of taking out more effectively, it is preferable that the tensile elasticity modulus of the window sticking film 20 is 0.1 MPa or more and 1.2 MPa or less. The tensile elastic modulus is a value obtained by dividing the tensile stress received by the window pasting film 20 by the strain generated in the window pasting film 20, and the smaller the value, the greater the deformation with respect to a constant load. The tensile modulus in the present invention was measured at a film width of 15 mm and a tensile speed of 500 mm / min.

  Furthermore, in order to suppress the generation | occurrence | production of paper dust and to improve taking-out property by improving the softness | flexibility of the film 20 for window sticking, it is preferable that the embossing is given to the film 20 for window sticking.

  The present invention has been described based on the embodiments. However, it goes without saying that the technical scope of the present invention is not limited to the scope of the invention described in the above embodiments. It will be apparent to those skilled in the art that improvements can be made. Further, it is apparent from the scope of the claims that embodiments with such changes or improvements can also be included in the technical scope of the present invention.
