Description

本発明は、紙ワイパーをポップアップ方式で取出し可能に収納箱に収納した紙ワイパー製品に関する。 The present invention relates to a paper wiper product in which a paper wiper is removably housed in a storage box in a pop-up manner.

紙ワイパーは、拭き取り性能、液体吸収性能などに優れることから、例えば、実験室や製造現場などにおいて、各種機器、装置、床面などの清掃作業などに広く使用されている。従来から、ティシュペーパーの収納と同様に（特許文献１、２参照）、紙ワイパーをいわゆるポップアップ方式に折り畳んだ積層体を収納箱に収納し、収納箱の天面に紙ワイパーの取出口を設けた紙ワイパー製品が普及している。 Paper wipers have excellent wiping performance, liquid absorption performance, etc., and are therefore widely used in laboratories, manufacturing sites, etc., for cleaning various equipment, devices, floors, and the like. Conventionally, in the same way as tissue paper is stored (see Patent Documents 1 and 2), a stack of paper wipers folded in a pop-up manner is stored in a storage box, and an outlet for the paper wiper is provided on the top of the storage box. Paper wiper products are becoming popular.

紙ワイパーを収納箱に収納する利点としては、帯での包装形態に比べ、定位置、定管理に適している点、剥き出しになっていないため衛生的である点、収納箱に入れたまま持ち運ぶことで、使用場所を移動しやすい点などが挙げられる。 The advantages of storing paper wipers in a storage box, compared to wrapping them in a band, are that they are suitable for fixed location and management, that they are hygienic because they are not exposed, and that they can be carried while in the storage box. This makes it easy to move from place to place.

紙ワイパーは、木材パルプ、古紙パルプ、非木材パルプ、それらの２種以上の混合物などの構成原料から製造され、拭き取り性能、液体吸収性能などの観点から、ティシューよりも坪量、紙厚が高く嵩張るものになる。このため、紙ワイパーを収納する収納箱は、背が高くかつ長細いものになりがちである。また、収納箱の材質も強度やコストなどの観点から段ボールが一般的である。すなわち、紙ワイパーの収納には、背の高い段ボール製収納箱（以下「段ボールカートン」とも称す）が用いられることが多い。 Paper wipers are manufactured from constituent materials such as wood pulp, waste paper pulp, non-wood pulp, and mixtures of two or more of these, and have a higher basis weight and paper thickness than tissue paper from the viewpoint of wiping performance and liquid absorption performance. It becomes bulky. For this reason, storage boxes for storing paper wipers tend to be tall and long. Further, the material of the storage box is generally cardboard from the viewpoints of strength and cost. That is, tall cardboard storage boxes (hereinafter also referred to as "cardboard cartons") are often used to store paper wipers.

特開２０００－２８１１５５号公報Japanese Patent Application Publication No. 2000-281155 特開２００５－２２５５６３号公報Japanese Patent Application Publication No. 2005-225563

しかしながら、背の高い段ボールカートンにポップアップ方式で紙ワイパーを収納すると、取り出すときに紙ワイパーが破れ易いという問題がある。これは、ティシュー製収納箱などよりも、段ボールカートンの方が紙ワイパーの取り出し抵抗が高いことが一因と考えられる。さらに、紙ワイパーの残量が減った状態で紙ワイパーを取り出すときに、紙ワイパーの積層体が段ボールカートンの下部に落ち込んでポップアップできなくなるドロップバックや段ボールカートンの倒れ易さ（不安定さ）などの問題もある。 However, when the paper wiper is stored in a tall cardboard carton in a pop-up manner, there is a problem in that the paper wiper is easily torn when taken out. One reason for this is thought to be that the paper wiper takes out the cardboard carton more easily than a tissue storage box. Furthermore, when taking out the paper wiper 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 be popped up, resulting in dropbacks and the tendency for the cardboard carton to fall over (instability). There is also the problem of

また、構成原料に古紙パルプを配合した紙ワイパーは、木材パルプを１００％使用したものに比べ破れやすい。 Additionally, paper wipers made of waste paper pulp are more likely to tear than wipers made of 100% wood pulp.

紙ワイパーを取り出すときの破れやすさや、ドロップバックを解決するには、紙ワイパーの強度を高くすることが考えられる。しかしながら、紙力増強剤などを配合して強度を高くすると、紙ワイパー自体の柔軟性や吸水性能の低下などの好ましくない効果が現われる。また、紙ワイパーの残量が少なくなった状態で、中の紙ワイパーを取り出したときの段ボールカートンの倒れ易さ（不安定さ）を改善するには、紙ワイパーと段ボールカートンとの抵抗が小さい事が求められる。 In order to solve the problem of paper wipers tearing easily and dropping back when taken out, it is possible to increase the strength of paper wipers. However, when a paper strength enhancer is added to increase the strength, undesirable effects such as a decrease in the flexibility and water absorption performance of the paper wiper itself appear. In addition, in order to improve the tendency of the cardboard carton to fall over (instability) when the paper wiper inside is removed when the remaining amount of paper wiper is low, it is necessary to have a small resistance between the paper wiper and the cardboard carton. things are required.

本発明の目的は、収納箱から取り出したときの紙ワイパーの破れやすさ、ドロップバック、収納箱の倒れ易さが改善された紙ワイパー製品を提供することである。 An object of the present invention is to provide a paper wiper product that has improved ease of tearing of the paper wiper when taken out from the storage box, dropback, and ease of the storage box falling over.

It is. 図１に示す収納箱の展開平面図である。FIG. 2 is a developed plan view of the storage box shown in FIG. 1. FIG.

以下、図面を参照しつつ、本発明の一実施形態である紙ワイパー製品１について詳細に説明する。図１（ａ）本発明の紙ワイパー製品１の外観を模式的に示す斜視図であり、図１（ｂ）は紙ワイパー製品１の使用時の外観を模式的に示す斜視図である。なお、図１中、矢印Ｘで示されるＸ方向、矢印Ｙで示されるＹ方向、及び矢印Ｚで示されるＺ方向は、それぞれ、収納箱１０の幅方向（又は短手方向）、幅方向に対して直交する収納箱１０の長手方向、並びに幅方向及び長手方向に対してそれぞれ直交する収納箱１０の高さ方向である。 Hereinafter, a paper wiper product 1 that is an embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1(a) is a perspective view schematically showing the appearance of the paper wiper product 1 of the present invention, and FIG. 1(b) is a perspective view schematically showing the appearance of the paper wiper product 1 when in use. In addition, in FIG. 1, the X direction shown by arrow The longitudinal direction of the storage box 10 is orthogonal to the storage box 10, and the height direction of the storage box 10 is orthogonal to the width direction and the longitudinal direction.

図１に示す紙ワイパー製品１は、破断させることにより取出口２ａが形成されるミシン目部２１を有する収納箱１０と、取出口２ａから取り出し可能なポップアップ方式の積層体（不図示）として収納箱１０内に収納された紙ワイパー６と、を備える。 The paper wiper product 1 shown in FIG. 1 is stored as a storage box 10 having a perforated portion 21 that forms an outlet 2a when broken, and a pop-up laminate (not shown) that can be taken out from the outlet 2a. A paper wiper 6 housed in a box 10 is provided.

より具体的には、図１に示すように、収納箱１０は、ミシン目部２１で囲まれた領域を有する頂面部２、これに対向する底面部３、頂面部２と底面部３とを連結する左右の側面部４、４’、５、５’により区画された直方体状の箱体である。また、収納箱１０の内部空間には、ポップアップ方式に積層された紙ワイパー６が収納されており、ミシン目部２１で囲まれかつ略円盤状の平面形状を有する領域の破断により形成される取出口２ａから紙ワイパー６を収納箱１０の外部へ取り出すことができる（図１（ｂ））。 More specifically, as shown in FIG. 1, the storage box 10 includes a top section 2 having an area surrounded by perforations 21, a bottom section 3 opposite to this, and the top section 2 and the bottom section 3. It is a box shaped like a rectangular parallelepiped divided by connecting left and right side parts 4, 4', 5, and 5'. In addition, paper wipers 6 stacked in a pop-up manner are stored in the internal space of the storage box 10, and the paper wipers 6 are stacked in a pop-up manner. The paper wiper 6 can be taken out of the storage box 10 from the outlet 2a (FIG. 1(b)).

図２は、収納箱１０の展開平面図である。図２に示す収納箱１０は、後述するように所定の厚みを有する段ボール製基材から構成され、例えば、頂面部２、底面部３及び左右の側面部４、４’、５、５’の各フラップを折り曲げ、各フラップの当接部分をホットメルト接着材などで接着することにより作製される。収納箱１０の基材となる段ボールは、例えば、古紙、バージンパルプ、これらの混合物などから構成される。 FIG. 2 is a developed plan view of the storage box 10. The storage box 10 shown in FIG. 2 is made of a cardboard base material having a predetermined thickness as described later, and includes, for example, a top surface 2, a bottom surface 3, and left and right side surfaces 4, 4', 5, and 5'. It is produced by bending each flap and gluing the abutting portions of each flap with hot melt adhesive or the like. The cardboard serving as the base material of the storage box 10 is made of, for example, waste paper, virgin pulp, a mixture thereof, or the like.

段ボール製基材の厚みは、１．０ｍｍ以上４．０ｍｍ以下、好ましくは２．０ｍｍ以上３．０ｍｍ以下である。前記範囲の厚みを有する段ボールを基材として用いることにより、収納箱１０の強度を保持しながら、収納箱１０の高さを４０ｍｍ以下、好ましくは３５ｍｍ以下とすることができる。その結果、後述する紙ワイパー６の改質と相俟って、ドロップバッグの発生が顕著に少なくなり、また、紙ワイパー６の残量が少なくなった状態で、紙ワイパー６を取り出したときの、収納箱１０の倒れ易さ（不安定さ）を改善することができる。 The thickness of the 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 a corrugated board having a thickness within the above range as the 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, together with the modification of the paper wiper 6 that will be described later, the occurrence of drop bags has been significantly reduced, and when the paper wiper 6 is taken out when the remaining amount of the paper wiper 6 is low, , the ease with which the storage box 10 falls (instability) can be improved.

本実施形態では、収納箱１０の立体形状は略直方体状であるが、複数の面及び紙ワイパー６を収納可能な内部空間を有する立体形状であれば特に制限されず、例えば、立方体状、円柱状、頂面部２及び頂面部２に略平行に離隔して対向する底面部３が長円状、４つの角が丸まった角丸長方形状などである立体形状などが挙げられる。これらの中でも、直方体状が好ましく、頂面部２において長辺方向が幅方向よりも２倍以上長い直方体状がより好ましい。 In the present embodiment, the three-dimensional shape of the storage box 10 is approximately rectangular parallelepiped, but the three-dimensional shape is not particularly limited as long as it has a plurality of surfaces and an internal space that can accommodate the paper wiper 6. For example, the three-dimensional shape is cubic, circular, etc. Examples include a columnar shape, a three-dimensional shape in which the top surface portion 2 and the bottom surface portion 3 facing the top surface portion 2 at a distance substantially parallel to the top surface portion 2 are oval shapes, 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 is twice or more longer than the width direction in the top surface portion 2 is more preferable.

取出口２ａ（又はミシン目部２１）の平面形状は本実施形態では円盤状であるが、これに限定されず、例えば、一方向に長い長方形やひし形、長円などが挙げられる。ミシン目部２１を手指、ペーパーナイフ、ナイフ、などで破断することにより、ミシン目部２１とほぼ同じ形状、及びほぼ同じ寸法を有し、収納箱内の紙ワイパー６を収納箱から外部に取り出すための取出口２ａが形成される。 Although the planar shape of the outlet 2a (or perforation 21) is disk-shaped in this embodiment, it is not limited to this, and examples thereof include a rectangle, a rhombus, and an ellipse that are long in one direction. By tearing the perforation part 21 with your fingers, a paper knife, a knife, etc., the paper wiper 6, which has approximately the same shape and dimensions as the perforation part 21 and is inside the storage box, is taken out from the storage box. An outlet 2a is formed for this purpose.

紙ワイパー６の積層体を収納箱１０に収納した状態で、取出口２ａの横幅（Ｙ方向の最大幅）は紙ワイパー６の横幅（Ｙ方向の最大幅）に対して６０％長さ以上７０％長さ以下、好ましくは６５％長さ以上６８％長さ以下とし、かつ取出口２ａの縦幅（Ｘ方向の最大幅）は紙ワイパー６の縦幅（Ｘ方向の最大幅）に対して４５％長さ以上５５％長さ以下、好ましくは４８％長さ以上５２％長さ以下とする。取出口２ａの横幅、及び縦幅をそれぞれ前記範囲に設定することにより、主に、紙ワイパー６の残量が少なくなった状態で、紙ワイパー６を取り出したときの、収納箱１０の倒れ易さ（不安定さ）を顕著に改善することができる。 When the stack of paper wipers 6 is stored in the storage box 10, the width of the outlet 2a (maximum width in the Y direction) is 60% or more of the width of the paper wiper 6 (maximum width in the Y direction). % 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 horizontal and vertical widths of the outlet 2a within the above-mentioned ranges, it is mainly possible to reduce the tendency of the storage box 10 to fall when the paper wiper 6 is taken out when the remaining amount of the paper wiper 6 is low. The stability (instability) can be significantly improved.

本実施形態では頂面部２に１つのミシン目部２１が設けられているが、これに限定されず、複数のミシン目部２１が１つの面に設けられてもよく、複数のミシン目部２１が複数の面に設けられてもよい。 In the present embodiment, one perforation 21 is provided on the top surface portion 2, but the present invention is not limited to this, and a plurality of perforations 21 may be provided on one surface, and a plurality of perforations 21 may be provided on one surface. may be provided on multiple surfaces.

収納箱１０の高さ（Ｚ方向の長さ）は特に限定されないが、例えば、ドロップバック、紙ワイパー６を取り出すときの収納箱１０の倒れ易さなどを改善する観点などから、好ましくは４０ｃｍ以下、より好ましくは３５ｃｍ以下とすることができる。本発明で使用する紙ワイパー６は、後述するように、嵩高いものであるが、製品密度が比較的低いことから、収納箱１０の高さを低くしても、紙ワイパー６の収納量の減少を抑制できる。また、紙ワイパー６と収納箱１０との接触抵抗が比較的小さいことから、収納箱１０の高さを４０ｃｍを超える範囲としても、ドロップダウンの発生や、紙ワイパー６を取り出すときの収納箱１０の倒れなどは従来技術に比べて抑制される。 The height (length in the Z direction) of the storage box 10 is not particularly limited, but is preferably 40 cm or less, for example, from the viewpoint of improving dropback and ease of the storage box 10 falling down when taking out the paper wiper 6. , more preferably 35 cm or less. The paper wiper 6 used in the present invention is bulky, as will be described later, but since the product density is relatively low, even if the height of the storage box 10 is reduced, the storage capacity of the paper wiper 6 will be reduced. Decrease can be suppressed. In addition, 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 is set to exceed 40 cm, drop-down may occur, and the storage box 10 may not be easily opened when the paper wiper 6 is taken out. The fall of the machine is suppressed compared to the conventional technology.

収納箱１０の一実施形態では、幅寸法（Ｘ方向の長さ）、長さ寸法（Ｙ方向の長さ）及び高さ寸法（Ｚ方向の長さ）は適宜選択できるが、一例をあげれば、幅寸法が１０ｃｍ以上２０ｃｍ以下である場合、長さ寸法が３０ｃｍ以上４０ｃｍ以下、及び高さ寸法が２０ｃｍ以上４０ｃｍ以下である。 In one embodiment of the storage box 10, the width dimension (the 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 selected as appropriate. 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.

収納箱１０は、図１（ｂ）に示すように、取出口２ａのＹ方向（長手方向）に沿うスリット３０を有し、ミシン目部２１の内面にその外周の少なくとも一部が接着されたフィルム部材（好ましくは透明性フィルム部材）２２をさらに備えていてもよい。フィルム部材２２は、ミシン目部２１を破断させ、取出口２ａを形成したときに、収納箱１０の頂面部２の表面に露出し、スリット３０を介して紙ワイパー６が取り出される。なお、フィルム部材２２は紙ワイパー６の収納箱１０には必須のものではない。 As shown in FIG. 1(b), the storage box 10 has a slit 30 along the Y direction (longitudinal direction) of the outlet 2a, and at least a part of its outer periphery is adhered to the inner surface of the perforation 21. It may further include a film member (preferably a transparent film member) 22. The film member 22 is exposed on the top surface 2 of the storage box 10 when the perforation 21 is torn to form the outlet 2a, and the paper wiper 6 is taken out through the slit 30. Note that the film member 22 is not essential to the storage box 10 for the paper wiper 6.

次に、紙ワイパー６について説明する。本実施形態では、紙ワイパー６は、ポップアップ方式に取出口２ａから取出し可能に積層された積層体として収納箱１０に収納されている。 Next, the paper wiper 6 will be explained. In this embodiment, the paper wiper 6 is housed in the storage box 10 as a stacked body that can be taken out from the takeout port 2a in a pop-up manner.

本実施形態の紙ワイパー６は、薄葉紙を複数枚、好ましくは２プライ（枚）以上１０プライ（枚）以下、より好ましくは３プライ（枚）以上６プライ（枚）以下を重ね合わせたものであるが、これに限定されず、１プライ（枚）であっても１０プライを超えてもよい。ここで薄葉紙１プライの坪量は特に限定はないが、通常は１５ｇ／ｃｍ２以上４５ｇ／ｃｍ２以下、好ましくは２０ｇ／ｃｍ２以上３８ｇ／ｃｍ２以下、より好ましくは２５ｇ／ｃｍ２以上３６ｇ／ｃｍ２以下である。また、紙ワイパー６の坪量は、紙ワイパー６を構成する薄葉紙のプライ（枚）数によって変わるが、例えばプライ数が３である場合は、通常４０ｇ／ｃｍ２以上１４０ｇ／ｃｍ２以下、好ましくは６０ｇ／ｃｍ２以上１２０ｇ／ｃｍ２以下、より好ましくは７０ｇ／ｃｍ２以上１１０ｇ／ｃｍ２以下である。紙ワイパー６の坪量が上記範囲にあることにより、複数枚の薄葉紙から構成される紙ワイパー６の引張強度、製品紙厚、及び製品密度を所定範囲に調整することが容易になる。 The paper wiper 6 of this embodiment is made by stacking a plurality of sheets of thin paper, preferably from 2 plies (sheets) to 10 plies (sheets), more preferably from 3 plies (sheets) to 6 plies (sheets). However, the number is not limited to this, and it may be one ply (sheet) or more than ten plies. Here, the basis weight of one ply of thin paper is not particularly limited, but is 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 / cm2 or less. Further, the basis weight of the paper wiper 6 varies depending on the number of plies (sheets) of thin paper 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, product paper thickness, and product density of the paper wiper 6 made of a plurality of sheets of thin paper to within a predetermined range.

引張強度、製品紙厚、及び製品密度を所定の範囲に調整し、収納箱１０から取り出した時の紙ワイパー６の破れやすさ、ドロップバック、収納箱１０の倒れ易さを改善する観点からは、本実施形態の紙ワイパー６としては、上記薄葉紙を２～６プライ（枚）重ね合わせたものであり、その坪量が４０ｇ／ｃｍ２以上１４０ｇ／ｃｍ２以下であるものが好ましい。 From the viewpoint of adjusting the tensile strength, product paper thickness, and product density within predetermined ranges, and improving the ease with which the paper wiper 6 is torn when taken out from the storage box 10, the dropback, and the ease with which the storage box 10 falls over. The paper wiper 6 of this embodiment is made by stacking 2 to 6 plies (sheets) of the above thin paper, and preferably has a basis weight of 40 g/cm 2 or more and 140 g/cm 2 or less.

本実施形態では、紙ワイパー６のＭＤ方向及びＣＤ方向の各引張強度を設定する。ＭＤ方向の引張強度（以下「ＤＭＤ」とも称す）は２８００ｇｆ／２５ｍｍ以上３８００ｇｆ／２５ｍｍ以下、好ましくは３２００ｇｆ／２５ｍｍ以上３５００ｇｆ／２５ｍｍ以下である。ＣＤ方向の引張強度（以下「ＤＣＤ」とも称す）は１４００ｇｆ／２５ｍｍ以上２４００ｇｆ／２５ｍｍ以下、好ましくは１７００ｇｆ／２５ｍｍ以上２１００ｇｆ／２５ｍｍ以下である。紙ワイパー６の製品紙厚は、紙ワイパー６を１０プライ（枚）重ねた状態で、２３０ｍｍ以上３．００ｍｍ以下、好ましくは２．６０ｍｍ以上２．７０ｍｍ以下とする。 In this 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 when 10 plies (sheets) of the paper wiper 6 are stacked.

このように、紙ワイパー６を高強度（高引張強度）化し、かつ低密度で嵩高い紙質に設計することにより、段ボール製の収納箱１０との摩擦抵抗も低減化し、例えば、紙ワイパー６を収納箱１０から取り出すときの破れ易さを改善し、ドロップバックの発生を顕著に低減できる。その結果、収納箱１０の高さを３５ｃｍ以下にすることも可能になり、収納箱１０の紙ワイパー６を取り出すときの安定性も向上し、紙ワイパー製品１の使用範囲及び使用方法が一層増加する。 In this way, by making the paper wiper 6 high-strength (high tensile strength) and designing it to be a low-density, bulky paper, the frictional resistance with the cardboard storage box 10 is also reduced. The ease of tearing when taken out from the storage box 10 can be improved, and the occurrence of dropbacks can be significantly reduced. As a result, it is now possible to reduce the height of the storage box 10 to 35 cm or less, and the stability when taking out the paper wiper 6 from the storage box 10 is improved, further increasing the scope and usage of the paper wiper product 1. do.

また、紙ワイパー６の製品密度は、紙プライ６を３プライ（枚）以上重ねた状態で、０．０８０ｇ／ｃｍ３以上０．１２０ｇ／ｃｍ３以下、好ましくは０．９５０ｇ／ｃｍ３以上１．０５０ｇ／ｃｍ３以下である。 In addition, the product density of the paper wiper 6 is 0.080 g/cm 3 or more and 0.120 g/cm 3 or less, preferably 0.950 g/cm 3 or more 1 when three or more paper plies 6 are piled up. .050g/ cm3 or less.

このように、紙ワイパー６を低密度にすることにより、紙ワイパー６を嵩高くしても、収納箱１０の高さを大きくする必要がなくなり、また、収納箱１０への紙ワイパー６の収納量が減ることを防止できる。すなわち、紙ワイパー６が低密度であることにより、紙ワイパー６が嵩高いものであっても、収納箱１０を必要以上に高くする必要がなくなる。さらに、前述のように、紙ワイパー６を高強度及び低密度に設計したことで、紙ワイパー６が適度な柔軟性や吸水性能を保持し、使用感が非常に良好なものになる。 In this way, by making the paper wiper 6 low-density, even if the paper wiper 6 is bulky, there is no need to increase the height of the storage box 10, and it is also possible to store the paper wiper 6 in the storage box 10. This can prevent the amount from decreasing. That is, since the paper wiper 6 has a low density, even if the paper wiper 6 is bulky, there is no need to make the storage box 10 unnecessarily high. Furthermore, as described above, the paper wiper 6 is designed to have high strength and low density, so that the paper wiper 6 maintains appropriate flexibility and water absorption performance, making it extremely comfortable to use.

また、本発明では、紙ワイパー６の引張強度を高めつつ、製品紙厚及び製品密度を所定の範囲とすることにより、紙ワイパー６の吸水性を高めることができる。本発明では、紙ワイパー６の吸水性は５００ｇ／ｍ２以上になり、好ましくは５５０ｇ／ｍ２以上１０００ｇ／ｍ２以下、より好ましくは５５０ｇ／ｍ２以上８００ｇ／ｍ２以下とすることができる。これにより、紙ワイパー６の清掃性能を向上させることができる。 Further, in the present invention, the water absorbency of the paper wiper 6 can be increased by increasing the tensile strength of the paper wiper 6 and setting the product paper thickness and product density within a predetermined range. In the present invention, the water absorption of the paper wiper 6 is 500 g/m 2 or more, preferably 550 g/m 2 or more and 1000 g/m 2 or less, 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.

紙ワイパー６は、木材パルプ、及び古紙パルプから選ばれる少なくとも１種を構成原料として、常法に従って製造できる。木材パルプには、例えば、針葉樹晒クラフトパルプ（ＮＢＫＰ）、広葉樹晒クラフトパルプ（ＬＢＫＰ）などがある。古紙パルプを含む構成原料から作製された紙ワイパー６は、木材パルプ１００％からなる構成原料から作製されたものに比べ、破れ易いことが知られている。しかしながら、本発明では、後述するように紙ワイパー６の所定の特性を所定範囲とすることにより、構成原料が古紙パルプを含んでいても、紙ワイパー６の強度を高め、収納箱１０から取り出すときの破れを防止することができる。紙ワイパー６の破れなどを防止する観点などから、古紙パルプを含む構成原料における、古紙パルプ含有量は構成原料全量の６０重量％以上１００重量％以下であることが好ましい。本実施形態の紙ワイパー６は、その特性を損なわない範囲で、木材パルプ及び古紙パルプ以外の構成材料を含むことができる。このような構成原料としては、例えば、非木材パルプや、填料、合成繊維、天然繊維などがある。 The paper wiper 6 can be manufactured by a conventional method using at least one selected from wood pulp and waste 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 from a raw material containing waste paper pulp is more easily torn than one made from a raw material made from 100% wood pulp. However, in the present invention, as will be described later, by setting the predetermined characteristics of the paper wiper 6 within a predetermined range, even if the constituent raw material contains waste paper pulp, the strength of the paper wiper 6 is increased, and when the paper wiper 6 is taken out from the storage box 10. can prevent tearing. From the viewpoint of preventing tearing of the paper wiper 6, etc., the waste paper pulp content in the constituent raw material containing waste paper pulp is preferably 60% by weight or more and 100% by weight or less of the total amount of the constituent raw material. The paper wiper 6 of this embodiment can contain constituent materials other than wood pulp and waste paper pulp within a range that does not impair its properties. Examples of such constituent materials include non-wood pulp, fillers, synthetic fibers, and natural fibers.

紙ワイパー６は、この分野の周知技術に従い、例えば、構成原料から作製された原紙ウエブを所定の条件でカレンダー成形することにより得ることができる。紙ワイパー６の引張強度は、例えば、構成原料として使用する古紙パルプ及び木材パルプの使用割合（重量％）を適宜選択することにより調整できる。また、紙ワイパー６の、製品坪量、製品密度、及び製品紙厚は、例えば、原紙ウエブのカレンダー成形条件及び必要に応じてエンボス加工条件を選択することにより調整できる。 The paper wiper 6 can be obtained, for example, by calendering a base paper web made from constituent raw materials under predetermined conditions, according to well-known techniques in this field. The tensile strength of the paper wiper 6 can be adjusted, for example, by appropriately selecting the proportions (% by weight) of waste paper pulp and wood pulp used as constituent raw materials. Further, the product basis weight, product density, and product paper thickness of the paper wiper 6 can be adjusted, for example, by selecting the calendering conditions of the base paper web and, if necessary, the embossing conditions.

本実施形態の紙ワイパー６は、エンボス加工を施したエンボス加工品であってもよい。エンボス加工品の形態は特に限定されないが、例えば、紙ワイパー６の一方及び他方の表面にそれぞれエンボス凸部及びそれに対応するエンボス凹部が形成された形態などが挙げられる。エンボス加工の方法としても特に限定されないが、例えば、エンボスロールを用いる方法などが挙げられる。エンボスパターンの形状や密度、エンボス面積率、エンボスエッジ率などは適宜選択できる。紙ワイパー６にエンボス加工を施すことにより、例えば、紙ワイパー６の嵩高さが増し、ドロップバックの発生をより一層低減化できる。 The paper wiper 6 of this embodiment may be an embossed product. Although the form of the embossed product is not particularly limited, for example, an embossed convex part and a corresponding embossed concave part are formed on one and the other surface of the paper wiper 6, respectively. The embossing method is not particularly limited, but examples include a method using an embossing roll. The shape and density of the embossed pattern, the embossed area ratio, the embossed edge ratio, etc. can be selected as appropriate. By embossing the paper wiper 6, for example, the bulkiness of the paper wiper 6 increases, and the occurrence of dropback can be further reduced.
