Description

The present invention relates to a paper wiper product in which a paper wiper is stored in a storage box so that it can be taken out by a pop-up method.

Paper wipers are excellent in wiping performance, liquid absorption performance, etc., and are therefore widely used for cleaning various devices, devices, floor surfaces, etc., for example, in laboratories and manufacturing sites. Conventionally, as in the case of storing tissue paper (see Patent Documents 1 and 2), a laminated body in which a paper wiper is folded in a so-called pop-up method is stored in a storage box, and a paper wiper outlet is provided on the top surface of the storage box. Paper wiper products are widespread.

The advantages of storing the paper wiper in the storage box are that it is suitable for fixed position and fixed management, that it is hygienic because it is not exposed, and that it is carried in the storage box. As a result, it is easy to move the place of use.

Paper wipers are manufactured from constituent raw materials such as wood pulp, recycled paper pulp, non-wood pulp, and mixtures of two or more of them, and have a higher basis weight and paper thickness than tissueu from the viewpoint of wiping performance and liquid absorption performance. It will be bulky. For this reason, the storage box for storing the paper wiper tends to be tall and long and thin. In addition, the material of the storage box is generally corrugated cardboard from the viewpoint of strength and cost. That is, a tall corrugated cardboard storage box (hereinafter, also referred to as "corrugated cardboard carton") is often used for storing the paper wiper.

Japanese Unexamined Patent Publication No. 2000-281155 Japanese Unexamined Patent Publication No. 2005-225563

However, if the paper wiper is stored in a tall cardboard carton by a pop-up method, there is a problem that the paper wiper is easily torn when it is taken out. It is considered that this is partly because the cardboard carton has a higher resistance to take out the paper wiper than the storage box made of tissue. Furthermore, when the paper wiper is taken out when the remaining amount of the paper wiper is low, the stack of paper wipers falls to the bottom of the cardboard carton and cannot pop up. There is also the problem of.

In addition, a paper wiper containing used paper pulp as a constituent raw material is more easily torn than a wiper using 100% wood pulp.

In order to solve the easiness of tearing when taking out the paper wiper and the dropback, it is conceivable to increase the strength of the paper wiper. However, when the strength is increased by adding a paper strength enhancer or the like, unfavorable effects such as a decrease in the flexibility and water absorption performance of the paper wiper itself appear. Also, in order to improve the easiness (instability) of the corrugated cardboard carton when the paper wiper inside is taken out when the remaining amount of the paper wiper is low, the resistance between the paper wiper and the corrugated cardboard carton is small. Things are required.

An object of the present invention is to provide a paper wiper product in which the ease of tearing of the paper wiper when taken out of the storage box, the dropback, and the ease of falling of the storage box are improved.

(A) A perspective view schematically showing the appearance of an embodiment of the paper wiper product according to the present invention, (b) A perspective view schematically showing the appearance of the paper wiper product according to the present invention when one embodiment is used. Is. It is a development plan view of the storage box shown in FIG.

Hereinafter, the paper wiper product 1 according to the embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1A is a perspective view schematically showing the appearance of the paper wiper product 1 of the present invention, and FIG. 1B is a perspective view schematically showing the appearance of the paper wiper product 1 in use. In FIG. 1, the X direction indicated by the arrow X, the Y direction indicated by the arrow Y, and the Z direction indicated by the arrow Z are in the width direction (or the lateral direction) and the width direction of the storage box 10, respectively. It is the longitudinal direction of the storage box 10 orthogonal to the direction, and the height direction of the storage box 10 orthogonal to the width direction and the longitudinal direction, respectively.

The paper wiper product 1 shown in FIG. 1 is stored as a storage box 10 having a perforation portion 21 in which an outlet 2a is formed by breaking, and a pop-up type laminated body (not shown) that can be taken out from the outlet 2a. A paper wiper 6 housed in the box 10 is provided.

More specifically, as shown in FIG. 1, the storage box 10 includes a top surface portion 2 having a region surrounded by a perforation portion 21, a bottom surface portion 3 facing the top surface portion 2, and a top surface portion 2 and a bottom surface portion 3. It is a rectangular parallelepiped box body partitioned by left and right side surface portions 4, 4', 5 and 5'to be connected. Further, a paper wiper 6 laminated in a pop-up manner is stored in the internal space of the storage box 10, and is formed by breaking a region surrounded by perforations 21 and having a substantially disk-shaped flat shape. The paper wiper 6 can be taken out of the storage box 10 from the outlet 2a (FIG. 1 (b)).

FIG. 2 is a developed plan view of the storage box 10. The storage box 10 shown in FIG. 2 is made of a corrugated cardboard base material having a predetermined thickness, as will be described later. For example, the top surface portion 2, the bottom surface portion 3, and the left and right side surface portions 4, 4', 5 and 5' It is produced by bending each flap and adhering the contact portion of each flap with a hot melt adhesive or the like. The corrugated cardboard used as the base material of the storage box 10 is composed of, for example, used paper, virgin pulp, a mixture thereof, and the like.

The thickness of the corrugated cardboard base material is 1.0 mm or more and 4.0 mm or less, preferably 2.0 mm or more and 3.0 mm or less. By using corrugated cardboard having a thickness in the above range as a base material, the height of the storage box 10 can be set to 40 mm or less, preferably 35 mm or less, while maintaining the strength of the storage box 10. As a result, in combination with the modification of the paper wiper 6 described later, the occurrence of drop bags is remarkably reduced, and when the paper wiper 6 is taken out with the remaining amount of the paper wiper 6 low. , The easiness of falling (instability) of the storage box 10 can be improved.

In the present embodiment, the three-dimensional shape of the storage box 10 is substantially rectangular parallelepiped, but the three-dimensional shape is not particularly limited as long as it has a plurality of surfaces and an internal space capable of accommodating the paper wiper 6, and is not particularly limited. Examples thereof include a columnar shape, a three-dimensional shape in which the bottom surface portion 3 facing the top surface portion 2 and the top surface portion 2 at a distance substantially parallel to the top surface portion 2 has an oval shape and a rounded rectangular shape with four rounded corners. Among these, a rectangular parallelepiped shape is preferable, and a rectangular parallelepiped shape in which the long side direction of the top surface portion 2 is twice or more longer than the width direction is more preferable.

The planar shape of the outlet 2a (or the perforation portion 21) is disk-shaped in the present embodiment, but is not limited to this, and examples thereof include a rectangle, a rhombus, and an oval that are long in one direction. By breaking the perforated portion 21 with a finger, a paper knife, a knife, etc., the paper wiper 6 having almost the same shape and dimensions as the perforated portion 21 and being taken out from the storage box is taken out from the storage box. The outlet 2a for the purpose is formed.

With the laminated body of the paper wiper 6 stored in the storage box 10, the width of the outlet 2a (maximum width in the Y direction) is 60% or more longer than the width of the paper wiper 6 (maximum width in the Y direction) 70. % Length or less, preferably 65% or more and 68% or less, and the vertical width (maximum width in the X direction) of the outlet 2a is relative to the vertical width (maximum width in the X direction) of the paper wiper 6. The length is 45% or more and 55% or less, preferably 48% or more and 52% or less. By setting the width and height of the outlet 2a to the above ranges, the storage box 10 is likely to fall down when the paper wiper 6 is taken out mainly when the remaining amount of the paper wiper 6 is low. The (instability) can be remarkably improved.

In the present embodiment, one perforation portion 21 is provided on the top surface portion 2, but the present invention is not limited to this, and a plurality of perforation portions 21 may be provided on one surface, and a plurality of perforation portions 21 may be provided. May be provided on a plurality of surfaces.

The height (length in the Z direction) of the storage box 10 is not particularly limited, but is preferably 40 cm or less from the viewpoint of improving the dropback, the easiness of the storage box 10 to fall when taking out the paper wiper 6, and the like. , More preferably 35 cm or less. As will be described later, the paper wiper 6 used in the present invention is bulky, but since the product density is relatively low, even if the height of the storage box 10 is lowered, the storage capacity of the paper wiper 6 is large. The decrease can be suppressed. Further, since the contact resistance between the paper wiper 6 and the storage box 10 is relatively small, even if the height of the storage box 10 exceeds 40 cm, dropdown occurs and the storage box 10 when the paper wiper 6 is taken out is generated. The collapse of the paper is suppressed as compared with the conventional technology.

In one embodiment of the storage box 10, the width dimension (length in the X direction), the length dimension (the length in the Y direction), and the height dimension (the length in the Z direction) can be appropriately selected. When the width dimension is 10 cm or more and 20 cm or less, the length dimension is 30 cm or more and 40 cm or less, and the height dimension is 20 cm or more and 40 cm or less.

As shown in FIG. 1B, the storage box 10 has a slit 30 along the Y direction (longitudinal direction) of the outlet 2a, and at least a part of the outer periphery thereof is adhered to the inner surface of the perforation portion 21. A film member (preferably a transparent film member) 22 may be further provided. When the perforation portion 21 is broken and the outlet 2a is formed, the film member 22 is exposed on the surface of the top surface portion 2 of the storage box 10, and the paper wiper 6 is taken out through the slit 30. The film member 22 is not essential for the storage box 10 of the paper wiper 6.

Next, the paper wiper 6 will be described. In the present embodiment, the paper wiper 6 is stored in the storage box 10 as a laminated body that can be taken out from the outlet 2a in a pop-up manner.

The paper wiper 6 of the present embodiment is a stack of a plurality of thin paper sheets, preferably 2 plies (sheets) or more and 10 plies (sheets) or less, and more preferably 3 plies (sheets) or more and 6 plies (sheets) or less. However, the present invention is not limited to this, and the number of plies may be 1 ply (sheets) or more than 10 plies. Here, the basis weight of the thin paper 1 ply is not particularly limited, but usually 15 g / cm ² or more and 45 g / cm ² or less, preferably 20 g / cm ² or more and 38 g / cm ² or less, more preferably 25 g / cm ² or more and 36 g. / Cm ² or less. The basis weight of the paper wiper 6 varies depending on the number of thin paper plies (sheets) constituting the paper wiper 6, but for example, when the number of plies is 3, it is usually 40 g / cm ² or more and 140 g / cm ² or less, preferably. Is 60 g / cm ² or more and 120 g / cm ² or less, more preferably 70 g / cm ² or more and 110 g / cm ² or less. When the basis weight of the paper wiper 6 is within the above range, it becomes easy to adjust the tensile strength, the product paper thickness, and the product density of the paper wiper 6 composed of a plurality of thin paper sheets within a predetermined range.

From the viewpoint of adjusting the tensile strength, product paper thickness, and product density within a predetermined range to improve the ease of tearing of the paper wiper 6 when taken out of the storage box 10, the dropback, and the ease of falling of the storage box 10. The paper wiper 6 of the present embodiment is preferably a stack of 2 to 6 plies (sheets) of the thin paper, and has a basis weight of 40 g / cm ² or more and 140 g / cm ² or less.

In the present embodiment, the tensile strengths of the paper wiper 6 in the MD direction and the CD direction are set. The tensile strength in the MD direction (hereinafter, also referred to as “DMD”) is 2800 gf / 25 mm or more and 3800 gf / 25 mm or less, preferably 3200 gf / 25 mm or more and 3500 gf / 25 mm or less. The tensile strength in the CD direction (hereinafter, also referred to as “DCD”) is 1400 gf / 25 mm or more and 2400 gf / 25 mm or less, preferably 1700 gf / 25 mm or more and 2100 gf / 25 mm or less. The product paper thickness of the paper wiper 6 is 230 mm or more and 3.00 mm or less, preferably 2.60 mm or more and 2.70 mm or less in a state where 10 plies (sheets) of the paper wiper 6 are stacked.

In this way, by increasing the strength (high tensile strength) of the paper wiper 6 and designing it to have a low density and bulky paper quality, the frictional resistance with the corrugated cardboard storage box 10 can also be reduced. For example, the paper wiper 6 can be used. The easiness of tearing when taken out from the storage box 10 can be improved, and the occurrence of dropback can be remarkably reduced. As a result, the height of the storage box 10 can be reduced to 35 cm or less, the stability when the paper wiper 6 of the storage box 10 is taken out is improved, and the range and method of use of the paper wiper product 1 are further increased. To do.

Furthermore, the product density of the paper wiper 6 is in a state of overlapping paper ply 6 3-ply (sheets) or, 0.080 g / cm ³ or more 0.120 g / cm ³ or less, preferably 0.950 g / cm ³ or more 1 .050 g / cm ³ or less.

By reducing the density of the paper wiper 6 in this way, even if the paper wiper 6 is made bulky, it is not necessary to increase the height of the storage box 10, and the paper wiper 6 is stored in the storage box 10. It is possible to prevent the amount from decreasing. That is, since the paper wiper 6 has a low density, it is not necessary to raise the storage box 10 more than necessary even if the paper wiper 6 is bulky. Further, as described above, by designing the paper wiper 6 with high strength and low density, the paper wiper 6 maintains appropriate flexibility and water absorption performance, and the usability becomes very good.

Further, in the present invention, the water absorption of the paper wiper 6 can be increased by setting the product paper thickness and the product density within a predetermined range while increasing the tensile strength of the paper wiper 6. In the present invention, the water absorption of the paper wiper 6 can be 500 g / m ² or more, preferably 550 g / m ² or more and 1000 g / m ² or less, and more preferably 550 g / m ² or more and 800 g / m ² or less. .. Thereby, the cleaning performance of the paper wiper 6 can be improved.

The paper wiper 6 can be produced according to a conventional method using at least one selected from wood pulp and used paper pulp as a constituent raw material. Examples of wood pulp include softwood bleached kraft pulp (NBKP) and hardwood bleached kraft pulp (LBKP). It is known that a paper wiper 6 made of a constituent raw material containing used paper pulp is more easily torn than a paper wiper 6 made of a constituent raw material made of 100% wood pulp. However, in the present invention, by setting a predetermined characteristic of the paper wiper 6 within a predetermined range as described later, even if the constituent raw material contains used paper pulp, the strength of the paper wiper 6 is increased and the paper wiper 6 is taken out from the storage box 10. Can be prevented from tearing. From the viewpoint of preventing tearing of the paper wiper 6, the content of the recycled paper pulp in the constituent raw material containing the recycled paper pulp is preferably 60% by weight or more and 100% by weight or less of the total amount of the constituent raw materials. The paper wiper 6 of the present embodiment can contain constituent materials other than wood pulp and used paper pulp as long as the characteristics are not impaired. Examples of such constituent raw materials include non-wood pulp, fillers, synthetic fibers, natural fibers and the like.

The paper wiper 6 can be obtained, for example, by calendar-molding a base paper web made from a constituent raw material under predetermined conditions according to a well-known technique in this field. The tensile strength of the paper wiper 6 can be adjusted, for example, by appropriately selecting the ratio (% by weight) of used paper pulp and wood pulp used as constituent raw materials. Further, the product basis weight, the product density, and the product paper thickness of the paper wiper 6 can be adjusted by, for example, selecting the calendar forming conditions of the base paper web and the embossing processing conditions as necessary.

The paper wiper 6 of the present embodiment may be an embossed product that has been embossed. The form of the embossed product is not particularly limited, and examples thereof include a form in which an embossed convex portion and a corresponding embossed concave portion are formed on one and the other surfaces of the paper wiper 6. The method of embossing is not particularly limited, and examples thereof include a method using an embossing roll. The shape and density of the embossed pattern, the embossed area ratio, the embossed edge ratio, and the like can be appropriately selected. By embossing the paper wiper 6, for example, the bulkiness of the paper wiper 6 can be increased, and the occurrence of dropback can be further reduced.

Hereinafter, the present invention will be described in detail with reference to examples. The present invention is not limited to the examples shown below.

(Examples 1 to 9 and Comparative Examples 1 to 9)
