特表２０１０−５０００８８号公報Special Table 2010-50088

当該清掃シートは、所定の薬液を含浸した湿潤状態で使用されることにより、清掃対象の汚れを溶解して拭うことや、家具などの艶出しを行うことが可能であった。
一方、清掃シートが湿潤状態で使用されるため、隣接するシート状部材同士が貼り付き、自重により懸下される現象が生じていた。当該現象によって、最初に清掃対象に当接される清掃シートの面積が減少されてしまうため、清掃当初において清掃シートの清掃領域を活用しにくい場合があった。
本発明は、このような点に鑑みて創案されたものであり、清掃領域を効率的に活用するための清掃シートおよび清掃用具に関する一層合理的な構築技術を提供することを目的とする。 By using the cleaning sheet in a wet state impregnated with a predetermined chemical solution, it was possible to dissolve and wipe the dirt to be cleaned and to polish furniture and the like.
On the other hand, since the cleaning sheet is used in a wet state, a phenomenon occurs in which adjacent sheet-shaped members stick to each other and are suspended by their own weight. Due to this phenomenon, the area of the cleaning sheet that first comes into contact with the object to be cleaned is reduced, so that it may be difficult to utilize the cleaning area of the cleaning sheet at the beginning of cleaning.
The present invention has been devised in view of these points, and an object of the present invention is to provide a more rational construction technique for a cleaning sheet and a cleaning tool for efficiently utilizing a cleaning area.

上記課題を解決するため、本発明に係る清掃シートは、所定の薬液が含浸される清掃シートであって、清掃対象に対して所定の清掃作業を行うことが可能に構成された清掃領域を有する。
清掃シートに含浸される薬液は、汚れを溶解するための界面活性剤や、ワックス剤が溶解された水溶液を使用することができる。また、清掃シートに対する薬液の含浸は製造過程において行うことができる。一方、使用者が乾燥状態の清掃シートに対して薬液を含浸させることも可能である。 In order to solve the above problems, the cleaning sheet according to the present invention is a cleaning sheet impregnated with a predetermined chemical solution, and has a cleaning area configured so that a predetermined cleaning operation can be performed on the object to be cleaned. ..
As the chemical solution impregnated in the cleaning sheet, a surfactant for dissolving stains or an aqueous solution in which a wax agent is dissolved can be used. Further, the cleaning sheet can be impregnated with the chemical solution in the manufacturing process. On the other hand, it is also possible for the user to impregnate the dry cleaning sheet with the chemical solution.

本発明に係る清掃シートでは、清掃領域は、第１シート状部材と第２シート状部材を積層することにより構成される。第１シート状部材は、吸水性繊維を有する不織布により構成されるとともに、所定の薬液が含浸され、第２シート状部材は、吸水性繊維を有する不織布により構成されるとともに、所定の薬液が含浸される。In the cleaning sheet according to the present invention, the cleaning area is formed by laminating a first sheet-shaped member and a second sheet-shaped member. The first sheet-like member is made of a non-woven fabric having water-absorbent fibers and impregnated with a predetermined chemical solution, and the second sheet-like member is made of a non-woven fabric having water-absorbent fibers and is impregnated with a predetermined chemical solution. Will be done.
第１シート状部材と第２シート状部材は、交互に配置することが可能である。The first sheet-shaped member and the second sheet-shaped member can be arranged alternately.
第１シート状部材が吸水性繊維を有する不織布により構成されることによって、第１シート状部材は、吸水性不織布により構成されるということができる。Since the first sheet-like member is made of a non-woven fabric having water-absorbent fibers, it can be said that the first sheet-like member is made of a water-absorbent non-woven fabric.
第２シート状部材が吸水性繊維を有する不織布により構成されることによって、第２シート状部材は、吸水性不織布により構成されるということができる。Since the second sheet-like member is made of a non-woven fabric having water-absorbent fibers, it can be said that the second sheet-like member is made of a water-absorbent non-woven fabric.

本発明に係る清掃シートによれば、第１シート状部材および第２シート状部材に薬液を効率的に含浸させることが可能となる。なお、吸水性繊維の代表的な例としては多孔質の構造を持つ繊維を挙げることができ、より具体的にはパルプ、コットン、麻などの天然繊維や、レーヨンなどの化学繊維を挙げることができる。さらに、不織布は、当該吸水性繊維と熱溶融繊維とを有することができる。熱溶融性繊維はポリエチレン、ポリプロピレン、ポリエステルなどを素材とする繊維が挙げられる。熱溶融繊維を使用することによって、第１シート状部材および第２シート状部材を、スパンレース不織布や、スルーエア不織布により得ることが可能となる。According to the cleaning sheet according to the present invention, the first sheet-shaped member and the second sheet-shaped member can be efficiently impregnated with the chemical solution. As a typical example of the water-absorbent fiber, a fiber having a porous structure can be mentioned, and more specifically, a natural fiber such as pulp, cotton and hemp, and a chemical fiber such as rayon can be mentioned. it can.

As shown in FIG. 1, the cleaning tool A100 is composed of a holder C100 and a cleaning sheet B100 that is detachable from the holder C100. The cleaning sheet B100 is configured with a holding area B110 on which the holder C100 is mounted. The area of the cleaning sheet B100 that comes into contact with the object to be cleaned constitutes the cleaning area B120. The cleaning tool A100 is an example of the "cleaning tool" according to the present invention, the holder C100 is an example of the "holder" according to the present invention, and the cleaning sheet B100 is an example of the "cleaning sheet" according to the present invention. Yes, the holding area B110 is an example of the "holding area" according to the present invention, and the cleaning area B120 is an example of the "cleaning area" according to the present invention.

清掃シートＢ１００は、清掃シートＢ１００のみで販売される場合と、清掃シートＢ１００と保持具Ｃ１００とが同時に梱包されて清掃用具Ａ１００として販売される場合がある。清掃シートＢ１００は、一回使用を目安とした使い捨てタイプのものや、清掃対象の被清掃面から除去したごみや埃を保持しつつ複数回の使用を目安として交換を行う使い捨てタイプのものであってもよい。 The cleaning sheet B100 may be sold only as the cleaning sheet B100, or the cleaning sheet B100 and the holder C100 may be packed at the same time and sold as the cleaning tool A100. The cleaning sheet B100 is a disposable type that is intended for single use, or a disposable type that is replaced with multiple uses while retaining dust and dirt removed from the surface to be cleaned. You may.

なお、清掃シートＢ１００には所定の薬液が含浸される。第１実施形態においては、製造工程において洗浄剤が含浸された清掃シートＢ１００に基づき説明を行う。乾燥重量の清掃シートＢ１００に対して２．５倍の重量を有する洗浄剤が含浸されている。 The cleaning sheet B100 is impregnated with a predetermined chemical solution. In the first embodiment, the description will be given based on the cleaning sheet B100 impregnated with the cleaning agent in the manufacturing process. It is impregnated with a cleaning agent having a weight 2.5 times that of the dry weight cleaning sheet B100.

図１に示す通り、清掃シートＢ１００は、所定の清掃シート第１方向Ｂ１００ｙと、清掃シート第２方向Ｂ１００ｘを規定する。清掃シート第２方向Ｂ１００ｘは清掃シート第１方向Ｂ１００ｙと交差する方向であり、清掃シートＢ１００の長尺方向は清掃シート第１方向Ｂ１００ｙに延在される。 As shown in FIG. 1, the cleaning sheet B100 defines a predetermined cleaning sheet first direction B100y and a cleaning sheet second direction B100x. The cleaning sheet second direction B100x is a direction that intersects the cleaning sheet first direction B100y, and the elongated direction of the cleaning sheet B100 extends to the cleaning sheet first direction B100y.

また、図３に基づき後述する通り、清掃シートＢ１００は第１シートＢ２１０と第２シートＢ２２０とを積層することにより構成される。この第１シートＢ２１０と第２シートＢ２２０が積層される方向は積層方向Ｂ１００ｚを規定する。積層方向Ｂ１００ｚは、清掃領域Ｂ１２０における最表面側により第１側Ｂ１００ｚ１を規定し、当該第１側Ｂ１００ｚ１と反対側である第２側Ｂ１００ｚ２を規定する。なお、図１１に基づき後述する第２実施形態に係る清掃シートＢ１０１は、保持領域Ｂ１１０の両側に清掃領域Ｂ１２０が構成されている。当該構成にあっては、いずれか一方の清掃領域Ｂ１２０における最表面側により第１側Ｂ１００ｚを規定することができる。 Further, as will be described later based on FIG. 3, the cleaning sheet B100 is configured by laminating the first sheet B210 and the second sheet B220. The direction in which the first sheet B210 and the second sheet B220 are laminated defines the stacking direction B100z. The stacking direction B100z defines the first side B100z1 by the outermost surface side in the cleaning region B120, and defines the second side B100z2 opposite to the first side B100z1. The cleaning sheet B101 according to the second embodiment described later based on FIG. 11 has cleaning areas B120 formed on both sides of the holding area B110. In this configuration, the first side B100z can be defined by the outermost surface side in either one of the cleaning areas B120.

保持領域Ｂ１１０は清掃シート第１方向Ｂ１００ｙに延在される。なお、清掃シート第１方向Ｂ１００ｙにおいて、清掃シートＢ１００に保持具Ｃ１００を装着する側は挿入側Ｂ１００ｙ１を規定し、清掃シートＢ１００から保持具Ｃ１００を抜去する側は離脱側Ｂ１００ｙ２を規定する。
なお、保持具Ｃ１００の延在方向は、清掃シートＢ１００に保持具Ｃ１００を装着した状態における、清掃シートＢ１００の延在方向に基づき規定される。すなわち、保持具Ｃ１００において、清掃シートＢ１００の保持部Ｂ３００に挿入される長尺部Ｃ１１０は、清掃シート第１方向Ｂ１００ｙに延在する。 The holding area B110 extends to the cleaning sheet first direction B100y. In the cleaning sheet first direction B100y, the side where the holder C100 is attached to the cleaning sheet B100 defines the insertion side B100y1, and the side where the holder C100 is removed from the cleaning sheet B100 defines the detachment side B100y2.
The extending direction of the holder C100 is defined based on the extending direction of the cleaning sheet B100 when the holder C100 is attached to the cleaning sheet B100. That is, in the holder C100, the long portion C110 inserted into the holding portion B300 of the cleaning sheet B100 extends in the cleaning sheet first direction B100y.

（清掃シートに係る説明）
図３から図９に基づき、清掃シートＢ１００の基本構成を説明する。まず、図３により清掃シートＢ１００の全体構成を説明する。図３は、図５に示される清掃シートＢ１００の平面図におけるＩ−Ｉ線断面図である。 (Explanation of cleaning sheet)
The basic configuration of the cleaning sheet B100 will be described with reference to FIGS. 3 to 9. First, the overall configuration of the cleaning sheet B100 will be described with reference to FIG. FIG. 3 is a sectional view taken along line II in a plan view of the cleaning sheet B100 shown in FIG.

図５に示す通り清掃シートＢ１００は、シート状要素を主体として構成される。シート状要素は、第１シートＢ２１０と、第２シートＢ２２０とを有する。この第１シートＢ２１０が本発明に係る「第１シート状部材」の一例であり、第２シートＢ２２０が本発明に係る「第２シート状部材」の一例である。
湿潤状態に置かれた第１シートＢ２１０は、湿潤状態に置かれた第２シートＢ２２０よりも剛性が低い低剛性部Ｂ２１５を構成する。また、湿潤状態に置かれた第２シートＢ２２０は、湿潤状態に置かれた第１シートＢ２１０よりも剛性が高い高剛性部Ｂ２２５を構成する。この低剛性部Ｂ２１５が本発明に係る「低剛性部」の一例であり、高剛性部Ｂ２２５が本発明に係る「高剛性部」の一例である。 As shown in FIG. 5, the cleaning sheet B100 is mainly composed of sheet-like elements. The sheet-like element has a first sheet B210 and a second sheet B220. The first sheet B210 is an example of the "first sheet-like member" according to the present invention, and the second sheet B220 is an example of the "second sheet-like member" according to the present invention.
The first sheet B210 placed in a wet state constitutes a low-rigidity portion B215 having a lower rigidity than the second sheet B220 placed in a wet state. Further, the second sheet B220 placed in a wet state constitutes a high-rigidity portion B225 having a higher rigidity than the first sheet B210 placed in a wet state. The low-rigidity portion B215 is an example of the "low-rigidity portion" according to the present invention, and the high-rigidity portion B225 is an example of the "high-rigidity portion" according to the present invention.

第１シートＢ２１０と、第２シートＢ２２０とは、ともに吸水性を有するスパンレース不織布により構成される。当該構成によって、第１シートＢ２１０と第２シートＢ２２０は、薬液を効率的に含浸することができる。より具体的には、第１シートＢ２１０における不織布の構成繊維と配合割合は、レーヨン繊維（親水性繊維）が５０パーセント、熱溶融繊維が３０パーセント、熱収縮繊維が２０パーセントである。第１シートＢ２１０において、熱溶融繊維はポリエチレンテレフタレートを芯材としポリエチレンを鞘材とする芯鞘複合繊維が用いられ、熱収縮繊維は融点の異なるポリプロピレンを並列することにより構成される、いわゆるサイドバイサイド型の構造を有する繊維が使用される。
また、第２シートＢ２２０における不織布の構成繊維と配合割合は、レーヨン繊維（親水性繊維）が５８パーセント、熱溶融繊維が１５パーセント、熱収縮繊維が２７パーセントである。第２シートＢ２２０において、熱溶融繊維はポリエチレンテレフタレート繊維が用いられ、熱収縮繊維は融点の異なるポリプロピレンを並列することにより構成される、いわゆるサイドバイサイド型の構造を有する繊維が使用される。なお、レーヨンは吸水性繊維ということができる。 The first sheet B210 and the second sheet B220 are both made of a spunlace non-woven fabric having water absorption. With this configuration, the first sheet B210 and the second sheet B220 can be efficiently impregnated with the chemical solution. More specifically, the constituent fibers and the compounding ratio of the non-woven fabric in the first sheet B210 are 50% for rayon fibers (hydrophilic fibers), 30% for heat-melted fibers, and 20% for heat-shrinkable fibers. In the first sheet B210, a core-sheath composite fiber having polyethylene terephthalate as a core material and polyethylene as a sheath material is used as the heat-melted fiber, and the heat-shrinkable fiber is a so-called side-by-side type composed of polypropylenes having different melting points arranged in parallel. Fiber having the structure of is used.
The constituent fibers and the blending ratio of the non-woven fabric in the second sheet B220 are 58% for rayon fibers (hydrophilic fibers), 15% for heat-melted fibers, and 27% for heat-shrinkable fibers. In the second sheet B220, polyethylene terephthalate fibers are used as the heat-melted fibers, and fibers having a so-called side-by-side type structure are used as the heat-shrinkable fibers, which are formed by arranging polypropylenes having different melting points in parallel. Rayon can be said to be a water-absorbent fiber.

なお、第１シートＢ２１０と第２シートＢ２２０に対し、乾燥重量の２．５倍の純水を含浸させた状態で、ＪＩＳＬ１０９６に規定される４５度カンチレバー法にて剛軟度の測定を行ったところ、第１シートＢ２１０は不織布のＭＤ方向が４０．９ｍｍであり、不織布のＣＤ方向が３６．５ｍｍであった。また、第２シートＢ２２０は不織布のＭＤ方向が６０．５ｍｍであり、不織布のＣＤ方向が４６．６ｍｍであった。なお、第１シートＢ２１０および第２シートＢ２２０における不織布のＭＤ方向は清掃シート第２方向Ｂ１００ｘと一致され、不織布のＣＤ方向は清掃シートＢ１００ｙと一致される。 The rigidity and softness of the first sheet B210 and the second sheet B220 were measured by the 45-degree cantilever method specified in JIS L 1096 in a state where the first sheet B210 and the second sheet B220 were impregnated with pure water 2.5 times the dry weight. As a result, the first sheet B210 had an MD direction of the non-woven fabric of 40.9 mm and a CD direction of the non-woven fabric of 36.5 mm. Further, in the second sheet B220, the MD direction of the non-woven fabric was 60.5 mm, and the CD direction of the non-woven fabric was 46.6 mm. The MD direction of the non-woven fabric in the first sheet B210 and the second sheet B220 coincides with the cleaning sheet second direction B100x, and the CD direction of the non-woven fabric coincides with the cleaning sheet B100y.

図３に示す通り、清掃シートＢ１００は、第１シートＢ２１０と第２シートＢ２２０を積層することにより構成される。なお、積層された第１シートＢ２１０と第２シートＢ２２０とは、第１接合部Ｂ４１０と、第２接合部Ｂ４２０とにより接合される。なお、第１接合部Ｂ４１０と第２接合部Ｂ４２０は隣接するシート状要素を熱溶着することにより構成される。
第１接合部Ｂ４１０は、清掃シート第２方向Ｂ１００ｘの中央において、積層方向Ｂ１００ｚの全域に亘り設けられる。第２接合部Ｂ４２０は、清掃シート第２方向Ｂ１００ｘにおいて第１接合部Ｂ４１０から所定の間隔を設けるとともに、積層方向Ｂ１００ｚの一部に亘り設けられる。すなわち、清掃シートＢ１００は、第２接合部Ｂ４２０により接合されるシート状要素と、第２接合部Ｂ４２０により接合されないシート状要素とを有する。保持領域Ｂ１１０は第２接合部Ｂ４２０に接合されるシート状要素により構成され、清掃領域Ｂ１２０は第２接合部Ｂ４２０に接合されないシート状要素により構成される。 As shown in FIG. 3, the cleaning sheet B100 is configured by laminating the first sheet B210 and the second sheet B220. The laminated first sheet B210 and the second sheet B220 are joined by the first joint portion B410 and the second joint portion B420. The first joint portion B410 and the second joint portion B420 are formed by heat welding adjacent sheet-like elements.
The first joint portion B410 is provided at the center of the cleaning sheet second direction B100x over the entire area of the stacking direction B100z. The second joint portion B420 is provided at a predetermined distance from the first joint portion B410 in the cleaning sheet second direction B100x, and is provided over a part of the stacking direction B100z. That is, the cleaning sheet B100 has a sheet-like element joined by the second joint portion B420 and a sheet-like element not joined by the second joint portion B420. The holding region B110 is composed of sheet-like elements joined to the second joint portion B420, and the cleaning region B120 is composed of sheet-like elements not joined to the second joint portion B420.

図４に基づき第１シートＢ２１０と第２シートＢ２２０の具体的な配置構造につき説明する。清掃領域Ｂ１２０の最表面（清掃シートＢ１００において最も第１側Ｂ１００ｚ１に位置する表面）には、第１シートＢ２１０が配置される。これによって、第１シートＢ２１０は、清掃対象に当接される清掃対象当接部を構成することができる。第１シートＢ２１０に隣接して第２シートＢ２２０が配置される。すなわち、清掃領域Ｂ１２０は第１シートＢ２１０と第２シートＢ２２０とを交互に積層することにより構成される。 A specific arrangement structure of the first sheet B210 and the second sheet B220 will be described with reference to FIG. The first sheet B210 is arranged on the outermost surface of the cleaning area B120 (the surface of the cleaning sheet B100 located on the first side B100z1). As a result, the first sheet B210 can form a cleaning target contact portion that comes into contact with the cleaning target. The second sheet B220 is arranged adjacent to the first sheet B210. That is, the cleaning area B120 is configured by alternately stacking the first sheet B210 and the second sheet B220.

また、保持領域Ｂ１１０は４つのシート状要素にて構成されており、第２側Ｂ１００ｚ２から第１側Ｂ１００ｚ１へ向かって第１シートＢ２１０、第１シートＢ２１０、第２シートＢ２２０、第２シートＢ２２０の順に配置されている。この内、隣接する第１シートＢ２１０における一対の第２接合部Ｂ４２０同士の間は、図２にて説明した保持具Ｃ１００の長尺部Ｃ１１０が装着される保持部Ｂ３００とされる。保持部Ｂ３００は、第１接合部Ｂ４１０により２つに分割されている。これによって、保持具Ｂ３００は、保持具Ｃ１００の第１延在部Ｃ１４１と第２延在部Ｃ１４２とを装着することが可能となる。 Further, the holding region B110 is composed of four sheet-like elements, and of the first sheet B210, the first sheet B210, the second sheet B220, and the second sheet B220 from the second side B100z2 toward the first side B100z1. They are arranged in order. Of these, between the pair of second joints B420 in the adjacent first sheet B210, there is a holding portion B300 on which the long portion C110 of the holder C100 described with reference to FIG. 2 is mounted. The holding portion B300 is divided into two by the first joint portion B410. As a result, the holder B300 can be equipped with the first extending portion C141 and the second extending portion C142 of the holder C100.

The first sheet B210 arranged on the secondmost side B100z2 is configured to have a shorter length in the cleaning sheet first direction B100y than the adjacent first sheet B210. With this configuration, the opening B310 of the holding portion B300 can be positioned inside the cleaning sheet B100. As a result, the user can easily arrange the first extending portion C141 and the second extending portion C142 of the holder C100 in the holding portion B300 via the opening B310.

図５に示す通り、第１シートＢ２１０は、外周から設けられた第１シート状部材切込み要素と、第１シート状部材短冊要素とを有することができる。第１シート状部材切込み要素は、複数の切込み部Ｂ２１３を有する。また、第１シート状部材短冊要素は、隣り合う切込み部Ｂ２１３の間に設けられた複数の短冊部Ｂ２１４を有することができる。この切込み部Ｂ２１３が本発明に係る「第１シート状部材切込み部」の一例であり、短冊部Ｂ２１４が本発明に係る「第１シート状部材短冊部」の一例である。

（清掃用具の動作に係る説明）
次に、図１０に基づき第１実施形態に係る清掃用具Ａ１００の動作につき説明を行う。なお、図１０においては説明の便宜上、保持具Ｃ１００を省略しているが、清掃作業を行う際には、使用者は、清掃シートＢ１００の保持部Ｂ３００に保持具Ｃ１００の第１延在部Ｃ１４１と第２延在部Ｃ１４２とを挿入し、清掃用具Ａ１００を構成する。これにより、湿潤した清掃シートＢ１００を使用者が保持して清掃作業を行う必要を無くすことが可能となる。 (Explanation related to the operation of cleaning tools)
Next, the operation of the cleaning tool A100 according to the first embodiment will be described with reference to FIG. Although the holder C100 is omitted in FIG. 10 for convenience of explanation, when performing the cleaning work, the user attaches the holding portion B300 of the cleaning sheet B100 to the first extending portion C141 of the holder C100. And the second extending portion C142 are inserted to form the cleaning tool A100. This makes it possible to eliminate the need for the user to hold the wet cleaning sheet B100 and perform the cleaning work.

使用者が把持部Ｃ１６３を把持した状態に置いては、清掃領域Ｂ１２０の第１シートＢ２１０および第２シートＢ２２０が自重により第１接合部Ｂ４１０を起点として重力方向に懸下される。この際、第１シートＢ２１０は低剛性部Ｂ２１５を構成し、第２シートＢ２２０は高剛性部Ｂ２２５を構成するため、低剛性部Ｂ２１５の方が、高剛性部Ｂ２２５と比して第１側Ｂ１００ｚ１へ大きく湾曲される。当該状態は、第１シートＢ２１０における清掃シート第２方向Ｂ１００ｘ上の端部と第１接合部Ｂ４１０とを結ぶ直線と積層方向Ｂ１００ｚとが形成する角度において第１側Ｂ１００ｚ１から臨んだ角度が、第２シートＢ２２０における清掃シート第２方向Ｂ１００ｘ上の端部と第１接合部Ｂ４１０とを結ぶ直線と積層方向Ｂ１００ｚとが形成する角度において第１側Ｂ１００ｚ１から臨んだ角度よりも小さく構成されるということができる。
当該構成によって、第１シートＢ２１０と第２シートＢ２２０との接触を抑制することができるため、第１シートＢ２１０と第２シートＢ２２０とが離間される状態を保ちやすくなる。よって、第１シートＢ２１０と第２シートＢ２２０とが貼り付くことによって、両シートがともに重力方向に懸下される状態を抑制することが可能となる。 When the user holds the grip portion C163, the first sheet B210 and the second sheet B220 of the cleaning area B120 are suspended in the direction of gravity from the first joint portion B410 by their own weight. At this time, since the first sheet B210 constitutes the low-rigidity portion B215 and the second sheet B220 constitutes the high-rigidity portion B225, the low-rigidity portion B215 is higher than the high-rigidity portion B225 on the first side B100z1. It is greatly curved to. In this state, the angle formed by the straight line connecting the end portion on the cleaning sheet second direction B100x and the first joint portion B410 in the first sheet B210 and the stacking direction B100z is the angle facing from the first side B100z1. The angle formed by the straight line connecting the end portion on the cleaning sheet second direction B100x and the first joint portion B410 in the second sheet B220 and the stacking direction B100z is smaller than the angle facing from the first side B100z1. Can be done.
With this configuration, contact between the first sheet B210 and the second sheet B220 can be suppressed, so that the state in which the first sheet B210 and the second sheet B220 are separated can be easily maintained. Therefore, by sticking the first sheet B210 and the second sheet B220, it is possible to suppress the state in which both sheets are suspended in the direction of gravity.

また、仮に第１シートＢ２１０と第２シートＢ２２０とが接触した場合であっても、第１シートＢ２１０の第２面Ｂ２１２には凸部Ｂ２１２ａと凹部Ｂ２１２ｂが構成され、第２シートＢ２２０の第１面Ｂ２２１には凸部Ｂ２２１ａを凹部Ｂ２２１ｂが構成されているため、両者の接触面積が減少されることとなる。よって、第１シートＢ２１０と第２シートＢ２２０とが接触した場合に生ずる両シートの貼り付き状態を回避可能とすることができる。なお、凸部Ｂ２１２ａおよび凹部Ｂ２１２ｂと凸部Ｂ２２１ａと凹部Ｂ２２１ｂとはともにランダム状に配置されているため、凹部Ｂ２１２ｂに凸部Ｂ２２１ａが入り込む状態や、凹部Ｂ２２１ｂに凸部Ｂ２１２ａが入り込む状態が回避可能となる。 Further, even if the first sheet B210 and the second sheet B220 are in contact with each other, the second surface B212 of the first sheet B210 is formed with a convex portion B212a and a concave portion B212b, and the first sheet B220 is the first. Since the surface B221 is formed with the convex portion B221a and the concave portion B221b, the contact area between the two is reduced. Therefore, it is possible to avoid the sticking state of both sheets that occurs when the first sheet B210 and the second sheet B220 come into contact with each other. Since the convex portion B212a, the concave portion B212b, the convex portion B221a, and the concave portion B221b are both randomly arranged, it is possible to avoid a state in which the convex portion B221a enters the concave portion B212b and a state in which the convex portion B212a enters the concave portion B221b. It becomes.

当該状態にあっては、使用者は第２側Ｂ１００ｚ２から第１側Ｂ１００ｚ１を臨んだ状態で清掃シートＣ１００の保持領域Ｂ１１０を目視しつつ、清掃対象の汚れに対して清掃領域Ｂ１２０の第１シートＢ２１０を当接させる。この際、使用者は、高剛性部Ｂ２２５（第２シートＢ２２０）により清掃シートＣ１００における清掃シート第２方向Ｂ１００ｘの長さを確認しつつ作業を進行することが可能となる。さらに、使用者は清掃領域Ｂ１２０の第１シートＢ２１０が第１接合部Ｂ４１０の近傍に懸下していることを意識可能となるため、汚れに対し的確に当該第１シートＢ２１０を押し当てることが可能となる。 In this state, the user visually observes the holding area B110 of the cleaning sheet C100 with the second side B100z2 facing the first side B100z1, and the first sheet of the cleaning area B120 against the dirt to be cleaned. Bring B210 into contact. At this time, the user can proceed with the work while confirming the length of the cleaning sheet second direction B100x in the cleaning sheet C100 by the high rigidity portion B225 (second sheet B220). Further, since the user can be aware that the first sheet B210 of the cleaning area B120 is suspended in the vicinity of the first joint portion B410, the first sheet B210 can be accurately pressed against the dirt. It will be possible.

なお、使用者が清掃シートＢ１００を清掃対象に押し当て、把持部Ｃ１６３により清掃シートＢ１００を操作した場合には、清掃領域Ｂ１２０の短冊部Ｂ２１４、Ｂ２２４が清掃作業を行う。この際、汚れが薬液により溶解され、短冊部Ｂ２１４、Ｂ２２４により拭われるが、使用者の操作により短冊部Ｂ２１４、Ｂ２２４同士が絡み合ったり、短冊部Ｂ２１４、Ｂ２２４の表裏が反転するなどの挙動を示す。一方、第１シートＢ２１０は第１面Ｂ２１１に凸部Ｂ２１１ａおよび凹部Ｂ２１１ｂを有し、第２面Ｂ２１２に凸部Ｂ２１２ａおよび凹部Ｂ２１２ｂを有する。さらに、第２シートＢ２２０は、第１面Ｂ２２１に凸部Ｂ２２１ａおよび凹部Ｂ２２１ｂを有し、第２面Ｂ２２２に凸部Ｂ２２２ａおよび凹部Ｂ２２２ｂを有する。よって、清掃作業中に短冊部Ｂ２１４、Ｂ２２４がどのような挙動を示しても、効率的に汚れを除去することが可能となる。
以上の通り、第１実施形態に係る清掃用具Ａ１００または清掃シートＢ１００は、清掃領域Ｂ１２０を効率的に活用することが可能となる。 When the user presses the cleaning sheet B100 against the object to be cleaned and operates the cleaning sheet B100 by the grip portion C163, the strip portions B214 and B224 of the cleaning area B120 perform the cleaning work. At this time, the dirt is dissolved by the chemical solution and wiped by the strips B214 and B224, but the strips B214 and B224 are entangled with each other by the operation of the user, and the front and back of the strips B214 and B224 are reversed. .. On the other hand, the first sheet B210 has a convex portion B211a and a concave portion B211b on the first surface B211 and a convex portion B212a and a concave portion B212b on the second surface B212. Further, the second sheet B220 has a convex portion B221a and a concave portion B221b on the first surface B221, and has a convex portion B222a and a concave portion B222b on the second surface B222. Therefore, no matter what behavior the strips B214 and B224 behave during the cleaning work, it is possible to efficiently remove the dirt.
As described above, the cleaning tool A100 or the cleaning sheet B100 according to the first embodiment can efficiently utilize the cleaning area B120.

（第２実施形態）
次に、第２実施形態に係る清掃用具を図１１に基づき説明する。図１１においては説明の便宜上、清掃シートＢ１０１を記載し、保持具Ｃ１００の記載を省略する。
第２実施形態に係る清掃シートＢ１０１は、第１実施形態に係る清掃シートと比して清掃領域Ｂ１２０の構成が異なる。すなわち、図１１に示す通り、清掃シートＢ１０１の清掃領域Ｂ１２０は、保持部Ｂ３００の第１側Ｂ１００ｚ１に設けられる第１清掃領域Ｂ１２１と、保持部Ｂ３００の第２側Ｂ１００ｚ２に設けられる第２清掃領域Ｂ１２２とを有する。この第１清掃領域Ｂ１２１は本発明に係る「第１清掃領域」の一例であり、第２清掃領域Ｂ１２２は本発明に係る「第２清掃領域」の一例である。 (Second Embodiment)
Next, the cleaning tool according to the second embodiment will be described with reference to FIG. In FIG. 11, for convenience of explanation, the cleaning sheet B101 is described, and the description of the holder C100 is omitted.
The cleaning sheet B101 according to the second embodiment has a different configuration of the cleaning area B120 as compared with the cleaning sheet according to the first embodiment. That is, as shown in FIG. 11, the cleaning area B120 of the cleaning sheet B101 is a first cleaning area B121 provided on the first side B100z1 of the holding portion B300 and a second cleaning area provided on the second side B100z2 of the holding portion B300. It has B122. The first cleaning area B121 is an example of the "first cleaning area" according to the present invention, and the second cleaning area B122 is an example of the "second cleaning area" according to the present invention.

清掃シートＢ１０１によれば、第１清掃領域Ｂ１２１が汚れた場合には、第２清掃領域Ｂ１２２により清掃作業を行うことができる。これによって、清掃シートＢ１０１を効率的に使用することが可能となる。 According to the cleaning sheet B101, when the first cleaning area B121 becomes dirty, the cleaning work can be performed by the second cleaning area B122. This makes it possible to efficiently use the cleaning sheet B101.

なお、本発明に係る清掃用具Ａ１００または清掃シートＢ１００の構成は、上述の構成に限るものでは無い。例えば、薬液としてワックス剤を使用することができる。また、使用者が清掃時に薬液を清掃シートに含浸させることができる。また、保持具Ｃ１００の長尺部Ｃ１１０は二股状のものでは無く、単一状の構成とすることができる。また、特に保持領域Ｂ１１０におけるシート状要素は、第１シートＢ２１０と第２シートＢ２２０とを所望の順序により積層することができる。 The configuration of the cleaning tool A100 or the cleaning sheet B100 according to the present invention is not limited to the above configuration. For example, a wax agent can be used as the chemical solution. In addition, the user can impregnate the cleaning sheet with a chemical solution at the time of cleaning. Further, the long portion C110 of the holder C100 is not bifurcated, but may have a single shape. Further, in particular, as for the sheet-like element in the holding region B110, the first sheet B210 and the second sheet B220 can be laminated in a desired order.
