Description
- The present invention relates to a cleaning member, a cleaning tool, and a folding structure for the cleaning member.
- Dusters have been known hitherto as a cleaning tool for removing dirt, dust or the like adhering to furniture such as chest of drawers, electronic products such as personal computers and lighting equipment, inner walls of buildings, doorsills, lintels and the like. However, the dusters merely sweep dust and dirt adhering to cleaning surfaces of objects to be cleaned and are not sufficient to capture dust and dirt.
-
Patent Literature 1 suggests a technique of wiping off dust or the like of the objects to be cleaned using a cleaning article provided with fiber bundles or the like including multiple fibers. Specifically, this cleaning article is equipped with brush parts on a cleaning surface side and both right and left sides of a base sheet, and the brush parts are formed by strip pieces of non-woven fabric and fiber bundles. In addition, the cleaning article forms a join line by joining a base sheet and a holding sheet to form a holding space between the base sheet and the holding sheet. The cleaning article is intended to be used as a cleaning member, and is used in a state of being incorporated into a cleaning tool by inserting a holding tool into the holding space of the cleaning member serving as the cleaning article during cleaning.
Patent Literature 2 discloses a cleaning member comprising a sheet structure with a fiber bundle in which multiple fibers are joined to a base sheet and a support handle insertion part for inserting a support handle is formed on the sheet structure, wherein the base sheet is formed in a tubular shape and has a space part formed in the interior thereof and the sheet structure joins the fiber bundle to an outer peripheral surface of the base sheet. -
- Patent Literature 1:
JP 2002-369783 A - Patent Literature 2:
US-A-20090169830 - The cleaning article of
Patent Literature 1 forms a state where fibers present around the holding space by directly joining the fiber bundle to an outer surface side of a portion forming the holding space of the base sheet. Moreover, the fibers located around the holding space capture dust and dirt adhering to the surface to be cleaned during cleaning. In order to clean a wider region using such a cleaning article, it is required to lengthen an overall length of the fibers forming the fiber bundles, increase an overall density of the fibers forming the fiber bundles, and increase a volume of the fiber bundles. The same is also true for a case of cleaning a more uneven region using the cleaning article ofPatent Literature 1. - However, there is a problem in that as the length of the fibers forming the fiber bundles is lengthened in the cleaning article of
Patent Literature 1, only a portion of a leading end side of the fiber is used for capturing dust and dirt during cleaning, a portion of the proximal end side of the fiber, which is a join portion formed by joined the fiber bundle and the base sheet, hardly comes into contact with the surface to be cleaned during cleaning and is hardly used for capturing dust and dirt, and it is not possible to effectively use the entire fibers forming the fiber bundles to capture the dust and dirt. Moreover, lengthening the overall length of the fibers forming the fiber bundle used in the cleaning article and increasing the overall density of the fibers cause an increase in manufacturing costs. Furthermore, there is a possibility that when lengthening the length of the fiber, entanglement is likely to occur at the leading end of the long fiber when transporting the cleaning article. - An object of the invention is to provide a cleaning member and a cleaning tool capable of sufficiently capturing dust and dirt, while suppressing a problem of an efficient use of the entire fibers during cleaning, and a problem of an increase in manufacturing costs in view of the above-described problems. Furthermore, another object of the invention is to provide a folding structure of the cleaning member that facilitates transportation of the cleaning member.

First, the cleaning member in a first embodiment of the invention will be described.
- As illustrated in an example of a cleaning
member 1a ofFigs. 1A, 1B, and 1C , a cleaningmember 1 of the first embodiment of the invention is configured to include asheet structure 4. In addition, in the cleaningmember 1, a direction along an insertion direction (a direction of an arrow E) of asupport handle 27 is assumed to be a longitudinal direction, a front side in the insertion direction is assumed to be a back side, and an inner side thereof is assumed to be a front face side. Furthermore, in regard to the cross-section of the cleaningmember 1, a cross-section observed when cutting the cleaningmember 1 along a plane in which a direction of an arrow E is a normal direction is assumed to be a cross-section of the cleaning member. In the example ofFigs. 1A to 1C , the insertion direction matches the longitudinal direction of thebase sheet 3. - The
sheet structure 4 is formed by joining at least onefiber bundle 2 to thebase sheet 3, and in the example illustrated inFigs. 1A to 1C , the sheet structure is configured by joining fourfiber bundles 2 to thebase sheet 3 to form bundle joinportions 11. Thesheet structure 4 joins thefiber bundles 2 on an outer peripheral surface of thebase sheet 3. Furthermore, in thesheet structure 4, thefiber bundles 2 are disposed so that the longitudinal direction of thefiber join portion 10 of thefiber bundle 2 is orthogonal to the longitudinal direction of thebase sheet 3 as viewed in a plan view of the cleaningmember 1. The expression "as viewed in the plan view of the cleaningmember 1" indicates a state when the cleaningmember 1 is viewed in a direction along a plane in which the longitudinal direction of thebase sheet 3 is the normal direction. - The
sheet structure 4 is formed with a supporthandle insertion part 6. Here, the supporthandle insertion part 6 is a portion having an insertion space part 7 into which a support handle to be described later for supporting thesheet structure 4 can be inserted in a predetermined direction. - The
base sheet 3 is a structure capable of stably forming a state in which thefiber bundles 2 are disposed in the cleaningmember 1, and is formed to include a thin sheetraw material 9 capable of being flexibly deformed. In appearance, thebase sheet 3 forms a tubularbody formed in a tubular shape with openings at both ends, is formed to have a cross-sectional circular shape when viewed in the cross-section of the tubular body while assuming the longitudinal direction of the tubular body to be the normal line, and forms aspace part 8 in a space within the tubular body. Furthermore, an external shape of thebase sheet 3 has a tubular shape in which an outer diameter of the cross-section from oneend surface 5a to theother end surface 5b is substantially constantly maintained. - The tubular body forming the
base sheet 3 is a material of the sheetraw material 9 and is not particularly limited as long as materials usable as thesheet rawmaterial 9 to be described later. - The
base sheet 3 is manufactured by, for example, forming the sheetraw material 9 as a tubular body in an appropriate tubular shape by rounding the sheetraw material 9, and by joining the sheetraw materials 9 to each other at a predetermined position to form ajoin portion 12. - As a shape of the sheet
raw material 9, it is possible to use a rectangular shape, but not limited thereto, the shape can be appropriately selected depending on the shape of thebase sheet 3 and the method of forming thebase sheet 3, and specifically, it is also possible to use a circular shape, an oval shape, an elliptical shape or the like. - Furthermore, the sheet
raw material 9 is not particularly limited, as long as sheet materials capable of forming a tubular structure of thebase sheet 3 and capable of forming a state of joining thefiber bundles 2 on the outer peripheral surface of thebase sheet 3 are adopted. Sheets such as paper, woven fabric, a synthetic resin sheet, non-woven fabric are preferably used as the sheet material. Among them, non-woven fabric is particularly preferably used from the viewpoint of light weight, strength, durability and adhesion. - As the non-woven fabric usable as the sheet
raw material 9, it is possible to use a spun lace non-woven fabric, a spun bond non-woven fabric, a thermal bond non-woven fabric, an air-through non-woven fabric, a point-bonded non-woven fabric or the like, but the spun bond non-woven fabric, and thermal bond non-woven fabric are preferred. As the fibers forming the non-woven fabric, any of natural fibers, synthetic fibers, and composite fibers may be used. The non-woven fabric preferably has a basis weight of about 20 to 100 g/m2. - The sheet
raw material 9 may be made of a piece of sheet material, may be formed by overlapping multiple pieces of sheet materials, and may be formed by laminating, joining, and integrating the sheet materials to one another. Furthermore, the sheetraw material 9 may be configured to have a plurality of portions having differentproperties. For example, the sheetraw material 9 may be configured by separately preparing two or more sheet materials such as the non-woven fabric and arranging these side by side (in a planar direction) to connect the end portions thereof to each other. As a method for connecting the end portions to each other, it is possible to appropriately adopt a method of bonding the end portions with adhesive, a method of joining the end portions by sewing or the like. - Furthermore, the
space part 8 of thebase sheet 3 is formed in the internal space of the tubular body forming thebase sheet 3 as described above. Thespace part 8 is formed as a space extending from one end surf ace 5 (5a) toward the other end surf ace 5 (5b) of thebase sheet 3 along the longitudinal direction of thebase sheet 3. And thespace part 8 is in a state of being opened on bothend surfaces base sheet 3 and communicating with the outside. - The size of the
space part 8 is not particularly limited, but is preferably greater than the size of the insertion space part 7 of the supporthandle insertion part 6. Here, it is assumed that the size of thespace part 8 and the size of the insertion space part 7 are a volume of thespace part 8 and a volume of the insertion space part 7 that are specified when assuming a state in which thespace part 8 and the insertion space part 7 are not crushed in the state of spreading the sheetraw material 9 surface of thebase sheet 3 forming thespace part 8 and thesheet piece 13 surface of the supporthandle insertion part 6. - Since the size of the
space part 8 is greater than the size of the insertion space part 7 of the supporthandle insertion part 6, even in cases where the surface to be cleaned is expanded over a wide region as well as a case where the surface to be cleaned is formed in a narrow region, it is possible to easily perform the effective cleaning of the region, and it is possible to obtain the cleaningmember 1 having a wide range capable of performing the effective cleaning. That is, when cleaning a narrow region, cleaning is performed without pressing the cleaningmember 1 against the surface to be cleaned, whereas, when cleaning a wide region, by pressing the cleaningmember 1 toward the surface to be cleaned, thespace part 8 is crushed along the pressing direction and thespace part 8 spreads along the cleaning surface, a contact area between thefiber bundles 2 and the surface to be cleaned is expanded, and it is possible to perform cleaning of a wider range. - In the example of
Figs. 1A to 1C , thejoin portion 12 is formed in a region (a region R inFigs. 3A and 3B ) between one end edge of the sheetraw material 9 forming thebase sheet 3 and a slightly inside position of the one end edge, and is formed in a band line shape extending in the longitudinal direction of the tubular body as thebase sheet 3. In the cleaningmember 1, the forming position or shape of thejoin portion 12 is not limited to the example ofFigs. 1A to 1C , and is appropriately set according to the shape or the method of forming thebase sheet 3. Specifically, the shape of thejoin portion 12 may be formed in an appropriate shape such as a curved shape, a dashed-line shape, a dotted shape, a fine line shape, and a wave shape. - As the method for forming the
join portion 12, itispossible to use a joining method using an adhesive. In this method, thejoin portion 12 is formed as a structural portion formed by joining the sheetraw materials 9 via anadhesive part 15 formed by applying the adhesive to apredeterminedposition of the sheetraw material 9. Furthermore, in this case, as the used adhesive, a two-liquid curable adhesive, a thermoplastic resin-based adhesive, an elastomeric adhesive, a thermosetting resin-based adhesive, an instant bonding adhesive, a hot-melt adhesive and the like. The adhesive is preferably the hot-melt adhesive from the viewpoint that is capable of performing the rapid joining work by cooling and heating. Furthermore, when the sheetraw material 9 is a non-woven fabric, a solution type or an emulsion type thermoplastic adhesive or elastomeric adhesive is preferable from the viewpoint of good permeability into the non-woven fabric. - The joining method using the adhesive described above is an example of a method of forming the
join portion 12, and in addition, as a method of forming thejoin portion 12, a joining method using a heat seal, and a joining method using an ultrasonic seal can be adopted. - The joining method using the heat seal is a method of heating a target portion trying to join the sheet
raw materials 9, and fusing the sheetraw materials 9 in the heating target portion and can be achieved using a heat sealing machine known hitherto. - The joining method using the ultrasonic seal is a method of instantly melting the target portion by applying fine ultrasonic vibration and pressure to the target portion trying to join the sheet
raw materials 9, and joining the sheetraw materials 9 in the target portion, and can be achieved using an ultrasonic sealing machine known hitherto. - The fiber bundles 2 are formed in a sheet shape by bundling a plurality of fibers, and as
such fiber bundles 2, it is possible to use fiber bundles in which each fiber forming the bundles are gathered to an extent of not being loosened to form afiber join portion 10. In thefiber bundles 2, in addition to thefiber join portion 10, the fibers may be further partially bonded to one another, by fusing, bonding the like as needed. - As illustrated in
Fig. 2 , thefiber bundle 2 can be specifically obtained by a following method or the like. In the method, a plurality oflong fibers 21 is bundled side by side to obtain along fiber bundle 20 in a sheet shape. A plurality oflong fibers 2 of thelong fiber bundle 20 are joined at intervals (with suitable intervals) in a direction (for example, a direction orthogonal to the longitudinal direction of the long fibers) intersecting with the flow direction of the long fibers to form long fiber joinportions 22. Then thelong fiber bundle 20 is cut an intermediate portion between the adj acent long fiber joinportions 22. At this time, the cut fibers form the fibers forming thefiber bundles 2 and the longfiber join portion 22 forms thefiber join portion 10 forming the fiber bundles 2. Furthermore, in the example of thefiber bundles 2, thefiber join portion 10 is formed at a central position in the flow direction of the fiber. - As the fibers forming the
fiber bundles 2, for example, natural fibers such as cotton, and wool, composite fibers such as polyethylene, polypropylene, polyethylene terephthalate, nylon, and polyacrylic, sheath-core fibers, sea-island type fibers, and side-by-side fibers are used, but when combining the fibers by partial heat sealing, core-sheath type composite fibers in which a core is made of polypropylene and a sheath is made of polyethylene are preferable, since the core-sheath type composite fibers have both excellent thermal adhesiveness of polyethylene forming the sheath and stiffness of polypropylene forming the core. The fibers forming thefiber bundles 2 are preferred to have a thickness of about 0.01 mm to 0.3 mm in diameter so as to be able to appropriately capture the dust. Furthermore, thefiber bundles 2 may be constituted only by the fibers having the same material, thickness, color and the like, and may be formed by fibers of two or more different types. In this case, with regard to onefiber bundle 2, thefiber bundle 2 may be formed by the plural types of the fibers in a state in which the fibers are generally mixed with one another. Thefiber bundle 2 may be formed in a state in which a potion comprised of fibers which have one predetermined type and a potion comprised of the fibers which have another predetermined type, are divided in regions. For example, in onefiber bundle 2, thefiber bundle 2 may be formed in a state in which blue fibers and yellow fibers are generally mixed with one another. Thefiber bundle 2 may be formed in a state in which a potion comprised of blue fibers and a potion comprised of yellow fibers are divided in regions. In thefiber bundles 2, when thefiber bundle 2 has plural potions which are formed by different color fibers respectively, and plural potions formed in divided regions, it is possible to obtain thefiber bundles 2 forming a pattern such as a patchy pattern, thereby improving design characteristics. - As the
fiber bundles 2, the fiber bundles formed by being bent or folded in the flow direction of the fibers forming the bundles may be used. The fiber bundles 2 formed with a folded potion by folding can be specifically achieved, for example, by taking an axis in the direction orthogonal to the flow direction of the fibers forming thefiber bundles 2 and at the substantially central position of thefiber bundle 2, folding thefiber bundles 2 in the flow direction of the fibers around the axis, and forming the folded section as the folded potion. - The
base sheet 3 may be provided with the plurality offiber bundles 2, in this case. Each of thefiber bundles 2 which is used on thebase sheet 3 may be formed with the fibers of the same material. Some of thefiber bundles 2 may be formed with the fibers of a material which is different from a material used the fibers in theother fiber bundles 2. The fiber bundles 2 may be respectively different from a material used the fibers. Furthermore, as the plurality offiber bundles 2, those obtained by combining the fibers of different properties may be used. For example, on the outer peripheral surface of thebase sheet 3, thefiber bundles 2 formed of fibers having water absorbency, and thefiber bundles 2 formed of fibers having chargeability may be provided. In this case, it is possible to wipe off the liquid dirt adhering to the surface to be cleaned by thefiber bundles 2 formed of the fibers having the water absorbency, and it is possible to electrostatically suck and wipe off the small dust adhering to the surface to be cleaned by thefiber bundles 2 having chargeability, and thus it is possible to manufacture the cleaningmember 1 having excellent cleaning performance. - Each of the
fiber bundles 2 may be formed of the fibers having the same color. Each of thefiber bundles 2 may be formed of the fibers having the different color. For example,white fiber bundles 2 and blue fiber bundles maybe alternately arranged on the outer surface side of thebase sheet 3. Furthermore, in regard to the color type of thefiber bundles 2, all thefiber bundles 2 may be different from one another. For example, when fourfiber bundles 2 are arranged on the outer surface side of thebase sheet 3, fiber bundles exhibiting red, blue, white, and yellow may be used. In such a case, it is possible to efficiently obtain the cleaningmember 1 having the excellent design properties. - Furthermore, in a case where the
base sheet 3 is provided with the plurality offiber bundles 2, when using thefiber bundles 2 constituted by the thin fibers and thefiber bundles 2 constituted by fibers thicker than these fibers in combination, since the thick stiff fibers function to scrape out the dust and the thin fibers function to capture the scrapped dust, it is possible to sufficiently capture from the finer dust to the large dust to some extent, thereby performing the effective cleaning. Here, as the fine fibers, those having the diameter of 0.01 mm to 0.05 mm are preferred. Furthermore, the thick fibers may be thicker than the fine fibers, but fibers having the thickness of the diameter of 0.06 mm to 0.3 mm are preferred. - In the cleaning
member 1, the bundle joinportion 11 is formed as a portion in which thefiber bundles 2 and thebase sheet 3 are joined to each other. The bundle joinportion 11 is formed in a direction intersecting with the flow direction (longitudinal direction) of the fibers forming the fiber bundles 2. In the example ofFigs. 1A to 1C , the bundle joinportion 11 is linearly formed, but is not limited thereto. The shape of the bundle joinportion 11 can be appropriately selected by a broken line shape, a curved line shape or the like. - The bundle join
portion 11 can be specifically formed as a part formed by bonding thefiber bundle 2 and thebase sheet 3 via an adhesive part which is formed by applying an adhesive to at least one predetermined position of thefiber bundle 2 and thebase sheet 3. Furthermore, the method of forming the bundle joinportion 11 illustrated herein is merely an example and is not intended to be limited thereto. For example, as the method of forming the bundle joinportion 11, methods applicable to the method of forming thejoin portion 12, such as a method of directly bonding both thefiber bundle 2 and thebase sheet 3 by heat fusion, may be used. - Furthermore, the method of forming the bundle join
portion 11 may be performed before or after manufacturing thebase sheet 3 from thesheet rawmaterial 9 or maybe simultaneously per formed. - In the cleaning
member 1, the supporthandle insertion part 6 is formed on thebase sheet 3. In the example ofFigs. 1A to 1C , the supporthandle insertion part 6 is formed by disposing thesheet piece 13 to face a predetermined position of thebase sheet 3 and joining a predetermined portion of thesheet piece 13 to thebase sheet 3 to form a sheet piece joinportion 14. Furthermore, the supporthandle insertion part 6 may have color different from those of the portions except for the supporthandle insertion part 6. For example, in the example ofFigs. 1A to 1C , the supporthandle insertion part 6 is formed by a portion, which is constituted by forming the insertion space part 7 of the sheetraw material 9 forming thebase sheet 3, and a portion constituted by thesheet piece 13. A Portion other than those portions in the cleaningmember 1 is a portion except for the supporthandle insertion part 6. In such a case, the supporthandle insertion part 6 is noticeable, and it is easy to insert the support handle 27 into the insertion space part 7. - The
sheet piece 13 is not limited to one formed in a strip shape as illustrated inFigs. 1A to 1C and can be appropriately selected depending on the shape of thebase sheet 3 and the shape of the supporthandle insertion part 6. Furthermore, as long as the material of thesheet piece 13 can be joined to thebase sheet 3, the material is not particularly limited, and specifically, it is possible to adopt the materials usable as the sheetraw material 9 forming thebase sheet 3, such as non-woven fabric. - In the cleaning
member 1, the sheet piece joinportion 14 is formed as a section in which thesheet piece 13 and thebase sheet 3 are joined to each other. - In the example of
Figs. 1A to 1C , the sheet piece joinportions 14 are formed in three positions which have respectively a linear shape extending in the longitudinal direction of thesheet piece 13 and are at both side edges of thesheet piece 13 and the center of the sheet piece. - However, the sheet piece join
portion 14 is merely an example, and is not intended to be limited to the forming position, number or shape, and can be appropriately selected based on the shape of the support handle to be inserted into the space part 7 of the supporthandle insertion part 6. For example, the shape of the sheet piece joinportion 14 may be a broken line shape as illustrated inFig. 6B , and in addition, it is possible to appropriately select a dotted line shape, a curved line shape, or the like. - The sheet piece join
portion 14 can be specifically formed by bonding thesheet piece 13 and thebase sheet 3 via the adhesive part which is formed by applying an adhesive to at least one predetermined position of thesheet piece 13 and thebase sheet 3. In addition, the method of forming the sheet piece joinportion 14 illustrated herein is merely an example and is not intended to be limited thereto. For example, as the method of forming the sheet piece joinportion 14, methods applicable to the method of forming the bundle joinportion 11 and thejoin portion 12 may be appropriately used. - In addition, the timing for carrying out the method of forming the sheet piece join
portion 14 may be before or after manufacturing thebase sheet 3 from the sheetraw material 9 in the same manner as in the method of forming the bundle joinportion 11, or may be simultaneous therewith. - With the formation of the support
handle insertion part 6, the insertion space part 7 is formed. The insertion space part 7 is formed in a shape capable of inserting the support handle. In the case of joining thesheet piece 13 to thebase sheet 3 as described above, a space is formed between thebase sheet 3 and thesheet piece 13, and this space forms the insertion space part 7. Here, the insertion space part 7 is formed as a space passing through the insertion direction (a direction indicated by an arrow E inFigs. 1A and15 ) of thesupport handle 27. Specifically, the insertion space part 7 extends in the longitudinal direction of thebase sheet 3 from the position of oneend surface 5a toward the position of theother end surface 5b of thebase sheet 3, and is a space opened and penetrated on both ends surface sides of oneend surface 5a and theother end surface 5b. When the insertion space part 7 is the penetrated space, it is possible to insert the support handle 27 from both oneend surface 5a side and from theother end surface 5b side. - In the cleaning
member 1, thespace part 8 of thebase sheet 3 and the insertion space part 7 of the supporthandle insertion part 6 are dividedly formed. That is, the insertion space part 7 is formed as a space partitioned from thespace part 8. In the example ofFigs. 1A to 1C , the space in the tubular body forming thebase sheet 3 is divided into two kinds by thesheet piece 13, one divided space forms the insertion space part 7 of the supporthandle insertion part 6, and the other space thereof forms thespace part 8. Furthermore, in the example ofFigs. 1A to 1C , thespace part 8 of thebase sheet 3 and the insertion space part 7 of the supporthandle insertion part 6 are in the state of being divided via thesheet piece 13. - As the size of the insertion space part 7, a size of an extent that at least the support handle can be inserted may be secured.
- For example, the cleaning
member 1 can be specifically manufactured as illustrated inFigs. 3A and 3B. Figs. 3A and 3B are diagrams for illustrating an example of the sheet structure raw material used in the execution of the manufacturing method of the cleaningmember 1 illustrated inFig. 1 - In manufacturing the cleaning
member 1, first, the sheetraw material 9 is prepared and thefiber bundles 2 formed with thefiber join portion 10 are prepared, and as illustrated inFig. 3A , thefiber bundles 2 are joined onto the surface of the sheetraw material 9 to form the bundle joinportions 11. Furthermore, thesheet piece 13 is joined onto the surface of the sheetraw material 9 to form the sheet piece joinportion 14,thereby forming the sheet structure raw material 17 (17a). - Next, an adhesive is applied to one end edge side of one surface 16 (16b) of the surfaces of the sheet
raw material 9 to form anadhesive part 15, and the whole sheet structureraw material 17a including the sheetraw material 9 is rounded by winding the sheetraw material 9 of sheet structureraw material 17a in the direction of the arrow P1 so that theadhesive part 15 faces a region R of the other end side of the sheetraw material 9 on the other surface 16 (16a) of the sheetraw material 9. Moreover, at the position of the region R of the sheetraw material 9, onesurface 16b and theother surface 16a of the sheetraw material 9 face each other via theadhesive part 15 and the sheetraw materials 9 are joined to each other to form thejoin portion 12. Thus, the sheet structureraw material 17a forms thesheet structure 4, and it is possible to manufacture the cleaningmember 1. - The cleaning
member 1 according to the invention can be used for wiping off the dust and dirt of the surface to be cleaned while cleaning. Furthermore, according to the cleaningmember 1 of the invention, since thefiber bundles 2 are provided on the outer peripheral surface of thebase sheet 3, a soft state is easily formed by forming a state in which the fibers are present on the entire peripheral surface of thebase sheet 3. - Furthermore, in the cleaning
member 1, it is easy to prepare thebase sheet 3 having the relatively great dimension of a cross-section by adjust the size of the sheetraw material 9. It is possible to obtain the cleaningmember 1, which is bulky as a whole, without depending on increasing the volume of the fibers forming the fiber bundles 2. - Therefore, even when a wide region is a surface to be cleaned, it is possible to easily obtain the cleaning
member 1 capable of cleaning such a wide region. Moreover, it is possible to suppress the need to lengthen the overall length of the fibers forming thefiber bundles 2, and it is possible to obtain the cleaningmember 1 capable of cleaning a wide region, while suppressing the need to increase the volume of thefiber bundles 2 by increasing the overall density of the fibers forming the fiber bundles 2. - When the cleaning
member 1 of the invention is carried, the cleaningmember 1 may be carried in a state in which the inner peripheral surface of thebase sheet 3 is unfolded outward as illustrated above, but maybe carried in a state of thefolding structure 46. - The
folding structure 46 is a folded structure of the cleaningmember 1, and is formed by folding thesheet structure 4 to form a foldedpart 47 and flattening thebase sheet 3 as illustrated inFig. 21A . Furthermore, in thefolding structure 46 of the cleaningmember 1, the inner surfaces of thebase sheet 3 of thesheet structure 4 adjacently face each other to form facing surfaces 60 (60a, 60b). Moreover, in thefolding structure 46, flattening thebase sheet 3 indicates that the inner surfaces of thebase sheet 3 are set to be a state of being closer to each other than before folding thesheet structure 4. At this time, in appearance, a state in which the volume of the portion of the cleaningmember 1 in which thefiber bundles 2 is present decrease is formed. Here, decreasing the volume indicates that when based on the volume of the portion of the cleaningmember 1 in which thefiber bundles 2 is present before being folded, in regard to the volume in the direction along the directions facing each other of the facing surfaces 60, 60, the apparent volume of the cleaningmember 1 in the portion in which thefiber bundle 2 is present decreases. - In the
folding structure 46, a foldedpart 47 is formed by appropriately folding thesheet structure 4 around a folding axis J (indicated by dashed lines inFigs. 1A to 1C (symbol J)) assumed at a predetermined position of thesheet structure 4. As long as the foldedpart 47 is formed to have a bulge in thebase sheet 3 when the support handle 27 is inserted into the supporthandle insertion part 6, the forming pattern, the forming position or the like thereof is not particularly limited. Specifically, in thefolding structure 46 formed with the folded part 47 (47a) as illustrated in the example ofFig. 21A , when the support handle 27 is inserted into the supporthandle insertion part 6, in appearance of the cleaningmember 1, the bulge is formed on thebase sheet 3. Furthermore, the portion in which thefiber bundles 2 of the cleaningmember 1 is present when the support handle 27 is inserted into the supporthandle insertion part 6 becomes bulky. The bulkiness described herein indicates that in regard to the bulkiness of the cleaningmember 1 along the directions facing to each other of the facing surfaces 60, 60, theapparent cleaning member 1 in the portion in which thefiber bundles 2 is present increases than before inserting the support handle 27 into the supporthandle insertion part 6. - As illustrated in
Fig. 21A , the foldedpart 47 is formed so as to position aprotruding end 49 thereof on the outer peripheral surface side of thesheet structure 4. - When the folded
part 47 is formed, the facingsurface 60 is formed. For example, thespace part 8 is narrowed by pressing thesheet structure 4 illustrated inFigs. 1A to 1C in the direction of arrow D1 toward the inside from the outside of the cleaningmember 1 as illustrated inFig. 21A , thebase sheet 3 is flattened in appearance, and the folded state of thesheet structure 4 is formed. At this time, thesheet structure 4 is bent inward (inner surface side direction of thesheet base 3; arrows V1 and V2 inFig. 21A ) around two folding axes J (J1, J2) assumed at a predetermined position of thesheet structure 4 to form the folded parts 47 (47a, 47b) and the facing surfaces 60 (60a, 60b) are formed on the inner surface side of thebase sheet 3. In addition, the facingsurfaces surfaces part 47, or may come into contact with each other. When the facingsurfaces part 47, thespace part 8 is in a crushed state. - The folded
part 47 is formed by folding thesheet structure 4 about the folding axis J once, but this is an example. For example, the foldedpart 47 may be formed in a pattern, such as locating the protrudingend 49 on the inner surface side of the tubular body forming thebase sheet 3 of thesheet structure 4. Thefoldedpart 47 can be formed by folding thesheet structure 4 so that thebase sheet 3 has a flat appearance by being pressed inward from the outside of the cleaningmember 1, while folding thesheet structure 4 so that a prearranged part as the protrudingend 49 is folded inside thesheet structure 4. In this case, the foldedpart 47 becomes a portion having a gazette structure. - Furthermore, in regard to the forming position of the folded
part 47, the foldedpart 47 can be formed at a position appropriately selected according to the configuration of the supporthandle insertion part 6 of the cleaningmember 1. - In the folded
part 47 illustrated in the example ofFig. 21A , there is one (foldedpart 47a inFig. 21A ) in which an axis along at least assumed folding axis J (J1) is formed at a position intersecting with theend portion 48 of the supporthandle insertion part 6. Specifically, the folding axis J1 is assumed on one sheet piece joinportion 14 formed between the adjacent insertion space parts 7 of the sheet piece joinportion 14 for joining thesheet piece 13 and thebase sheet 3 forming the supporthandle insertion part 6 as illustrated inFig. 1B along the sheet piece joinportion 14, and thesheet structure 4 is bent around the folding axis J1 to form the foldedpart 47 (47a). In addition, this is not intended to limit the forming position of the foldedpart 47 only to the above-described position. For example, by assuming the folding axis J at a position deviated from the sheet piece joinportion 14 while intersecting with theend portion 48 of the supporthandle insertion part 6 and folding thesheet structure 4 therearound, the foldedpart 47 may be formed. - Furthermore, when the support handle insertion part 7 is constituted by joining the plurality of
sheet pieces 13 andbase sheets 13 prepared separately to form the plurality of insertion space parts 7 as illustrated inFig. 4B , the foldedpart 47 may be formed, by assuming the folding axis J at a predetermined position located between the respective insertion space parts 7 along the surface of thebase sheet 13, and folding thesheet structure 4 around the folding axis J. In this case, the folding axis J assumed in forming the foldedpart 47 may not intersect with theend portion 48 of the supporthandle insertion part 6. - At least two folded
parts 47 are formed. In thefolding structure 46 ofFig. 21A , two folded parts 47 (47a and 47b) are formed at the positions facing each other so that the protruding end of theflat base sheet 3 becomes theprotruding end 49 of the foldedpart 47. - If one (folded
part 47a) of the foldedparts 47 is formed to have a bulge in thebase sheet 3 when inserting the support handle 27 into the supporthandle insertion part 6, the forming position of the other (foldedpart 47b) of foldedparts 47 is not particularly limited. When differences are observed in stiffness and thickness of thebase sheet 3 between thejoin portion 12 and a non-join portion in the cleaningmember 1, in view of implementation easiness of folding of thesheet structure 4, as illustrated inFigs. 21A and 21B , the foldedpart 47b is preferably the portion which is formed by being bent thesheet structure 4 at aboundary position 61 which is a boundary between thejoin portion 12 and the non-join portion. - This can be specifically achieved by configuring the cleaning
member 1 so as to mate the portion serving as the folding axis J2 and the boundary positions 61 when thesheet structure 4 is pressed in the direction of arrow D1. In addition, this does not exclude a case that the foldedpart 47b is formed at the positions other than theboundary position 61 between thejoin portion 12 and the non-join portion. - In the
folding structure 46, thebase sheet 3 is flat, andspace part 8 is in a thin state or a crushed state. However, with the insertion of the support handle 27 into the supporthandle insertion part 6 of thefolding structure 46, as illustrated inFig. 21B , the tubular space of thebase sheet 3 is pushed in the direction of arrow D2, the flat state of thebase sheet 3 of thesheet structure 4 is released, expansion of thespace part 8 is restored in the tubular space of thebase sheet 3, the bulge is formed in thebase sheet 3, and the cleaningmember 1 in which the folded state is released is formed. That is, when the support handle 27 is inserted into the supporthandle insertion part 6 of thefolding structure 46, the cleaningmember 1 restores a three-dimensional state compared to the folded state prior to insertion of thesupport handle 27. - In regard to the configuration of the support handle 27 to be inserted into the
folding structure 46, the support handle 27 is not particularly limited. That is, as illustrated inFig. 21B , the support handle 27 inserted into thefolding structure 46 is not limited to one having twosupport rods part 28 into two parts, but may be one having one support rod, and may be one having a structure which has three or four support rods and are divided into three or four parts, respectively. Furthermore, the shape of the support rod may be one formed in an appropriate shape in addition to a round bar shape, and a square bar shape. - The cleaning
member 1 is not limited to one having asheet structure 4 as illustrated above, and may be one in which each part such as thefiber bundles 2 forming thesheet structure 4 is configured as will be described below. - In the
sheet structure 4, thefiber bundles 2 are not limited to the case of forming thefiber join portion 10 at the central position in flow direction of the fibers. As illustrated inFig. 8A , thefiber bundles 2 may be configured so that thefiber join portion 10 is formed at a position or location that is laterally offset from the central position in the flow direction of the fibers. That is, when assuming a distance from thefiber join portion 10 to one end (one free end) of the fibers to be W1, and assuming a distance to the other end (the other free end) to be W2, W1 and W2 may be different values from each other. In addition, in thesheet structure 4, in the case of W1 > W2, thefiber bundles 2 are preferably disposed so that portions of the fibers of applying W1 of thefiber bundles 2 are disposed on the outer side in thesheet structure 4. In this case, by adjusting the value of W1, it is possible to more efficiently suppress the exposure of the portion of theend surface 5 of thebase sheet 3 while cleaning. Furthermore, in this case, it is possible to easily maintain the state in which the flexible fibers are present in a portion corresponding to the portion of theend surface 5 of thebase sheet 3 in thesheet structure 4, thereby improving the flexibility of that portion. - In addition, the
end surface 5 of thebase sheet 3 is covered withfiber bundles 2 in thesheet structure 4, but the exposure suppression of the portion of theend surface 5 of thebase sheet 3 can be achieved by adjusting the dimensions of thebase sheet 3 so that theend surface 5b of thebase sheet 3 is positioned inside the free end of thefiber bundle 2, as illustrated inFig. 8B . - Furthermore, in the
sheet structure 4, the arrangement of thefiber bundles 2 is not limited to those illustrated above. As illustrated inFig. 7A , the fiber bundles may be disposed so that the longitudinal direction of thefiber join portion 10 of thefiber bundle 2 is a direction along the longitudinal direction of thebase sheet 3. Furthermore, as illustrated inFig. 7B , thefiber bundles 2 may also be disposed so that the longitudinal direction of thefiber join portion 10 of thefiber bundle 2 becomes a direction that diagonally crosses the longitudinal direction of thebase sheet 3. - In the
sheet structure 4, thefiber bundles 2 are not limited to a case of being directly joined to the outer peripheral surface of thebase sheet 3, and may be indirectly joined to the outer peripheral surface of thebase sheet 3 via anintervention sheet piece 26 as illustrated inFigs. 14A and 14B . Theintervention sheet piece 26 is not particularly limited as long as it is made of materials capable of being joined to both thefiber bundles 2 and thebase sheet 3. Specifically, theintervention sheet piece 26 may be appropriately selected from the sheet materials usable as the sheetraw material 9. - The
sheet structure 4 provided with theintervention sheet piece 26 can be obtained as follows. That is, as illustrated inFig. 19B , theintervention sheet piece 26 is joined to thefiber bundle 2 in advance to form an inter-bundle intervention sheet piece joinportion 42, thereby forming acoupling piece 41. Next, thecoupling piece 41 is joined to the sheetraw material 9 to form a state of indirectly joining thefiber bundles 2 to the sheetraw material 9 via theintervention sheet piece 26. Here, as a method of joining thefiber bundles 2 and theintervention sheet piece 26, and a method of joining theintervention sheet piece 26 and the sheetraw material 9, it is possible to appropriately select the same method as the method of forming thejoin portion 12. Furthermore, the shape of the join portion between theintervention sheet piece 26 and the sheetraw material 9 can be appropriately selected, and is not limited to a linear shape, a dotted shape or the like. Furthermore, theintervention sheet piece 26 may be joined to all over the sheetraw material 9, or may be partly joined thereto. In this way, thecoupling piece 41 is appropriately joined to the sheetraw material 9, and thesheet piece 13 is joined to the sheetraw material 9 to form a sheet structure raw material as necessary, and then, the sheet structure raw material is appropriately rounded and thejoin portion 12 is formed to manufacture thesheet structure 4. Moreover, the cleaningmember 1 is obtained by preparing thesheet structure 4 in this manner. - In addition, the shape of the
intervention sheet piece 26 can be appropriately selected depending on the shape of the fiber bundles 2. Theintervention sheet piece 26 is formed in a piece shape in the example ofFigs. 14A and 14B . In addition, the size of theintervention sheet piece 26 can be appropriately selected, but, as illustrated inFig. 19B , the size can be set within a range in which it is possible to position the outer peripheral edge of theintervention sheet piece 26 inside the reach (a fiber movable range K) of the free ends of the fibers forming thefiber bundle 2 as viewed in a plan view of thecoupling piece 41. In this case, it is possible to suppress the possibility that the state of exposing theintervention sheet piece 26 to the outside of the free ends of the fibers forming thefiber bundle 2 occurs more than necessary in the cleaningmember 1. Here, the fiber movable range K is constituted by a fiber movable range K1 in the longitudinal direction and a fiber movable range K2 in a width direction, in the longitudinal direction and the width direction of thefiber bundles 2, respectively. As viewed in a plan view of thecoupling piece 41, the fiber movable range K1 is an outside range along the longitudinal direction (the direction of extension of thefiber join portion 10 inFig. 19B ) of thefiber bundle 2 from the positions X1 and X2 of each join portion end based on the position X (X1 and X2) of the join portion end of thefiber join portion 10, and is a reach of the free ends of the fibers forming the fiber bundles 2. As viewed in the plan view of thecoupling piece 41, the fiber movable range K2 is a reach of the free ends of the fibers forming thefiber bundle 2, which is a range between both join portion ends of the fiber join portion 10 (between X1 and X2), and is an outside range along the width direction of the fiber bundles 2. - Positioning the outer edge of the
intervention sheet piece 26 inside the fiber movable range K can be specifically achieved as follows. As illustrated inFig. 19A , the intervention sheet pieceraw material 35 is prepared, and the coupling pieceraw material 36 obtained by joining thefiber bundles 2 thereto is prepared. At this time, in the coupling pieceraw material 36, an inter-bundle intervention sheet piece raw material join portion 37 is formed in a joining portion between thefiber bundle 2 and the intervention sheet pieceraw material 35. In the coupling pieceraw material 36,perforations 38 are provided at a predetermined position of the intervention sheet pieceraw material 35. By means of tearing the intervention sheet pieceraw material 35 by theperforations 38, the outer portion of theperforations 38 in the intervention sheet pieceraw material 35 is removed. At this time, the intervention sheet pieceraw material 35 forms theintervention sheet piece 26, the inter-bundle intervention sheet piece raw material join portion 37 forms an inter-bundle intervention sheet piece joinportion 42, and thecoupling piece 41 is prepared. In addition, the position of theperforations 38 is selected so that the peripheral edge of theintervention sheet piece 26 is located at the outer position than the inter-bundle intervention sheet piece joinportion 42 and is located inside the contour position of the fiber movable range K. - After the
coupling piece 41 is adjusted, the sheet structure raw material, in which thecoupling piece 41 is provided in the sheetraw material 9 as indicated above, is prepared. Then the cleaningmember 1 can be prepared by using the sheet structure raw material. - Furthermore, as the
perforations 38, inFig. 19A , ones extending along the respective directions for both the longitudinal direction and the width direction of thefiber bundles 2 are provided, but not limited thereto, and ones expending in at least one direction may be provided. - In the
sheet structure 4, thebase sheet 3 is not limited to a case of being formed by joining the free end portions of the end edge side of the sheetraw material 9 to form thejoin portion 12 while allowing onesurface 16b and theother surface 16a of the sheetraw material 9 to face each other, but as illustrated inFig. 4D , thebase sheet 3 can be formed by joining the free endportions of the endedge side of thesheet rawmaterial 9 to form thejoin portion 12 while allowing one surfaces 16b of the sheetraw material 9 to face each other. Furthermore, thebase sheet 3 may also be formed by joining the free end portions of the end edge side of the sheetraw material 9 to form thejoin portion 12 while allowing theother surfaces 16a of the sheetraw material 9 to face each other as illustrated inFig. 4E . - Furthermore, the
base sheet 3 is not limited to the case of being formed by joining the free end portions of the end edge side of the sheetraw material 9 to form thejoin portion 12. As illustrated inFig. 4C , thebase sheet 3 may also be formed by joining the free end portion of the end edge side of the sheetraw material 9 and a predetermined portion close to the center of the sheetraw material 9 while facing each other to form thejoin portion 12. In the example ofFig. 4C , the join portion 12 (12a) is formed by joining theother surface 16a side of the free end portion of one end edge of the sheetraw material 9 to the predetermined portion close to the center of theother surface 16a of the sheetraw material 9 to face each other, and the join portion 12 (12b) is formed by joining the onesurface 16b side of the free end portion of the other end edge side of the sheetraw material 9 to the predetermined portion close to the center of the onesurface 16b of the sheetraw material 9 to face each other. Moreover, thebase sheet 3 is formed with a space part 23 (23a) formed in a state in which theother surface 16a of the sheetraw material 9 faces the inner surface side, and a space part 23 (23b) formed in a state in which the onesurface 16b of the sheetraw material 9 faces the inner surface side, thesheet piece 13 is attached to the inner surface of the space part 23 (23b) in a state in which the onesurface 16b of the sheetraw material 9 faces the inner surface side to form the insertion space part 7 and to form the supporthandle insertion part 6. At this case, aspace part 8 is formed as a space group constituted by aresidual space 34 obtained by subtracting the part forming the supporthandle insertion part 6 from thespace part 23b, and thespace part 23a. - As illustrated in
Figs. 20C and 20D , thebase sheet 3 may also include a structure which is formed in a tubular shape by obliquely winding the parallelogram-shaped sheetraw material 9, as a tubular body. The cleaningmember 1 equipped with such abase sheet 3 can be obtained as follows. As illustrated inFig. 20A , ajoin portion structure 44 is obtained by joining thefiber bundles 2 to one surface of the rectangular sheetraw material 9. The predetermined portions of the two side edge sides forming a short side of the sheetraw material 9 of thejoin portion structure 44 are cut in a direction obliquely crossing the longitudinal direction of thejoin portion structure 44 to obtain a cuttingtarget joining body 45 having almost a parallelogram shape as viewed in a plan view as illustrated inFig. 20B , and the parallelogram-shaped sheetraw material 9 is formed. Furthermore, the tubular structure is formed by winding the cuttingtarget joining body 45 around the axis (indicated by symbol M in theFig. 20B ) along the direction perpendicular to the direction along the short side of the cuttingtarget joining body 45. At this case, when forming thejoin portion 12 by joining the facing portions of the side end surfaces of the sheetraw material 9 to each other, the shape of the tubular structure is stabilized. Moreover, by joining thesheet piece 13 at a predetermined position of the tubular structure, for example, at a predetermined position such as the inner surface of the tubular structure illustrated inFig. 20D , thesheet structure 4 is formed, and the cleaningmember 1 is obtained. In addition, even in this case,multiple fiber bundles 2 may be disposed and maybe disposed such that the longitudinal direction of thefiber bundles 2 becomes the direction crossing the longitudinal direction of the sheetraw material 9. - The support
handle insertion part 6 is not limited to the case of being formed by joining onesheet piece 13 and thebase sheet 3 as illustrated in the example ofFigs. 1A to 1C . As illustrated inFigs. 4A and 4B , themultiple sheet pieces 13 may be joined to thebase sheet 3 to form the insertion space part 7 by thesheet piece 13 and thebase sheet 3, respectively, and the supporthandle insertion part 6 may be formed by combining the individually formed insertion space parts 7. - Furthermore, in
Figs. 1A to 1C , the supporthandle insertion part 6 is formed by two insertion space parts 7, but may be formed by one insertion space part 7, and as illustrated inFig. 4B , the supporthandle insertion part 6 may be formed by three insertion space parts 7 and may be formed by more than four insertion space parts 7 (not illustrated). - Furthermore, the
sheet piece 13 is not limited to the case of being joined to a predetermined position on the inner peripheral surface side of thebase sheet 3 as illustrated in the example ofFigs. 1A to 1C , and may be joined to a predetermined position of the outer peripheral surface side of thebase sheet 3 to form a sheet piece joinportion 14 as illustrated inFig. 4F . In this case, the support portion insertion part 7 is formed on the outer peripheral surface side of the base sheet, and theinsertion space part 6 is formed to be spaced apart fromspace part 8 via thebase sheet 3. Furthermore, in this case, thefiber bundles 2 may be disposed to cover the exposed outer surface of thesheet piece 13 as illustrated inFig. 4F , and may be disposed to avoid the arrangement portion of thesheet piece 13. - The insertion space part 7 is not limited to the case of being formed as the space passing through the insertion direction of the support handle 27 as described above. That is, the insertion space part 7 is not limited to the case of being formed as a space that is opened on both end surface sides of the one
end surface 5a and theother end surface 5b of thebase sheet 3 and passes from the position of the oneend surface 5a of thebase sheet 3 toward the position of theother end surface 5b. As illustrated inFigs. 6A and 6B , the insertion space part 7 may be formed as a space (a space that does not penetrate) having closed one side of the oneend surface 5a and theother end surface 5b of thebase sheet 3. Such a space can be formed by forming acrossing join portion 24 in the supporthandle insertion part 6 so as to cross the extension direction of the insertion space part 7 (direction facing theother end surface 5b from oneend surface 5a of the base sheet 3) as the insertion direction. In the example ofFig. 6A , the crossing joinportion 24 is formed linearly by joining thesheet piece 13 and thebase sheet 3 to each other at a predetermined position slightly inner from the position of theother end surface 5b. In a case where the insertion space part 7 is a space that does not pass through the cleaningmember 1, when the support handle 27 is inserted from the oneend surface 5a side or theother end surface 5b side, it is possible to reliably prevent the fear of the penetration of the leading end of the support handle 27 to the opposite side. - In the
sheet structure 4, thebase sheet 3 is not limited to the case of being formed using one sheetraw material 9, and may be formed using the multiple sheetraw materials 9 as in a second embodiment described below. - In regard to the
sheet structure 4, the description has been given of a case where thebase sheet 3 forms as a circular shape in a cross-section view taking in a vertical direction in which both end surfaces 5 (5a, 5b) side are open, but are not limited thereto. The cross-sectional shape of thebase sheet 3 can be appropriately selected. Here, the cross-section of thebase sheet 3 indicates the shape of the section of thebase sheet 3 recognized when assuming the state of cutting thebase sheet 3 in a plane having a normal line in a direction along the longitudinal direction of thebase sheet 3. The cross-sectional shape of thebase sheet 3 is not limited to a circular cross-sectional shape as in the example ofFigs. 1A to 1C . Specifically, thebase sheet 3 may have a deformed cross-sectional shape such as an elliptical shape, and a shape formed by combining a plurality of circular shapes as illustrated inFigs. 13A, 13B, and 13C . The deformed cross-sectional shape is assumed to indicate the cross-sectional shapes other than a circular cross-sectional shape. - In addition, the
sheet structure 4 as illustrated inFigs. 13A and 13B can be prepared using thesheet structure 4 as illustrated in the example of the cleaningmember 1a ofFigs. 1A to 1C . That is, in regard to thesheet structure 4 as illustrated inFigs. 1A to 1C , two different positions of the tubular space side of thebase sheet 3 are selected and joined linearly along the longitudinal direction of thebase sheet 3 at the two positions, thereby forming the join portion 12 (12c) . As a result, thesheet structure 4 as illustrated inFigs. 13A and 13B is formed. At this case, thespace part 8 is formed as a space group formed by thespace part 23c and thespace part 23d. Furthermore, thesheet structure 4 as illustrated inFig. 13C can be prepared, by selecting two different positions of the tubular space side of thebase sheet 3 with respect to thesheet structure 4 as illustrated inFig. 13B and linearly joining in the longitudinal direction of thebase sheet 3 at the two positions to form the join portion 12 (12d), as well as thejoin portion 12c. In this case, thespace part 8 is formed as a space group including thespace part 23c, thespace part 23d, and thespace part 23e. - Since the
sheet structure 4 is configured so that thebase sheet 3 has the deformed cross-sectional shape as illustrated inFigs. 13A to 13C as described above, it is possible to diversify the contact state with the surface to be cleaned. - In the
sheet structure 4, the external shape of thebase sheet 3 is not limited to the case of openingboth-side end surfaces 5 side, while forming the tubular shape in which the substantially constant outer diameter of the cross-section is maintained from oneend surface 5a toward theother end surface 5b, and thebase sheet 3 may have a shape of a state in which at least a part is closed by crushing the opening of at least a part of the cross-section of theother end surface 5b side position in thebase sheet 3, as illustrated in the example ofFigs. 9A to 9C . In thesheet structure 4 as illustrated in the example ofFigs. 9A to 9D , thebase sheet 3 is formed with acrushed part 18 on theother end surface 5b side by closing at least a part of theother end surface 5b side. - The
sheet structure 4 illustrated inFigs. 9A to 9D can be specifically prepared using thesheet structure 4 as illustrated inFigs. 1A to 1C . That is, after preparing thesheet structure 4 illustrated inFigs. 1A to 1C , two positions of a predetermined position of theother end surface 5b side as the inner surface side of the tubular body forming thebase sheet 3 and a predetermined position on thesheet piece 13 are selected to form the crushing target part, and the crushing target parts of the two positions are joined to each other in a dotted shape to form anend join portion 25. At this time, the cross-sectional shape of thebase sheet 3 is in a state of being crushed by the position of the end joinportion 25 and the periphery thereof, the state of crushing theother end surface 5b of thebase sheet 3 is formed to form the crushedpart 18. At this time, as illustrated inFig. 9B , the cleaningmember 1 has a shape tapered toward the position of theother end surface 5b side from the position of the oneend surface 5a of thebase sheet 3 when the one side surface is viewed from a predetermined position. However, for example, when the cleaningmember 1 is viewed in a direction rotated by 90 degrees about an axis in the longitudinal direction of thebase sheet 3 with respect to the predetermined direction, as illustrated inFig. 9A , the cleaningmember 1 has a shape expanded from the position of oneend surface 5a toward the position of theother end surface 5b of thebase sheet 3. In addition, the multiple end joinportions 25 are formed. Furthermore, when the end joinportions 25 are formed at the central position of thebase sheet 3 or in the vicinity thereof, thesheet structure 4 has a shape narrowed toward the center from the position of theend surface 5 of thebase sheet 3. - As the multiple crushing target positions for forming the end join
portions 25, the multiple positions may be selected only from the inner surface side of the tubular body forming thebase sheet 3. In this case, the crushing target portion is not selected from a predetermined position on thesheet piece 13. - The crushed
part 18 is not limited to the case of being formed by joining the crushed target positions of two different positions as the inner surface side of the tubular body forming thebase sheet 3 and the predetermined position on theother end surface 5b side in a dotted shape to form the end joinportion 25. The crushedpart 18 may be formed by forming the end joinportion 25 as illustrated inFigs. 10A and 10B . That is, as illustrated inFigs. 10A and 10B , the different three positions (Fig. 10A ), four positions (Fig. 10B ) or more positions as the inner surface side of the tubular body forming thebase sheet 3 and the predetermined position of theother end surface 5b side are selected as the crushing target positions, and the crushing target positions are joined to one another in a dotted shape, thereby forming the end joinportion 25. For convenience of description, inFigs. 10A and 10B , thesheet piece 13 and the fiber bundles are not illustrated, and in regard to thebase sheet 3, the portion of theend surface 5b is also illustrated by extraction. - Furthermore, the end join
portion 25 is not limited to the case of being formed by joining the multiple different positions as the inner surface side of the tubular body forming thebase sheet 3 and the predetermined position of theother end surface 5b side in a dotted shape. As illustrated inFig. 9D , the end joinportions 25 may be formed by linearly joining thebase sheet 3 on theother end surface 5b side of thebase sheet 3. Furthermore, at this case, as illustrated inFig. 11 , pleats may be formed at the position of the end joinportion 25. That is, in thebase sheet 3 illustrated inFig. 11 , the state in which theother end surface 5b side of thebase sheet 3 is more effectively crushed is formed, by adding a configuration in which theother end surface 5b side is crushed to form the pleats to a configuration in which the end joinportion 25 is linearly formed, and thecrushed part 18 has a shape that is narrowed at theother end surface 5b side of thebase sheet 3. - Since the cleaning
member 1 forms the crushedpart 18 in thebase sheet 3 of thesheet structure 4, it is possible to use the crushedpart 18 side of the cleaningmember 1 as the leading end side of the cleaningmember 1, and the cleaningmember 1 can be formed as a tapered shape toward the leading end, the leading end of the cleaningmember 1 can slip into a narrow space, and cleaning of the narrow space can be easily performed. - The cleaning
member 1 may have a configuration in which thenotch part 31 as illustrated inFigs. 12A and 12B is provided in thebase sheet 3 to form the multiple strip-like parts 32 in thesheet structure 4. - In the example of
Figs. 12A and 12B , thenotch part 31 is formed by extending oneend surface 5a side and theother end surface 5b side of thebase sheet 3 to form theextended part 33, and by adding a plurality of notches toward the proximal end from the extension leading end of theextended part 33. Furthermore, the strip-like part 32 is formed as a portion interposed between theadjacent notch parts Fig. 12B , it is preferred to apply the notch so as to avoid the supporthandle insertion part 6. When thenotch part 31 is also applied to the supporthandle insertion part 6, the strip-like part 32 is also formed in the supporthandle insertion part 6, but, in that case, it is feared that the strip-like part 32 may interfere with insertion of thesupport handle 27. - In addition, in the example illustrated in
Figs. 12A and 12B , on both oneend surface 5a side and theother end surface 5b side of thebase sheet 3, theextended parts 33 are formed, and thenotch parts 31 are formed, but one configuration of theextended part 33 and thenotch part 31 may be formed on at least one of the oneend surface 5a and theother end surface 5b of thebase sheet 3. Furthermore,Figs. 12A and 12B are an example, the notch part may be formed to a position entered thebase sheet 3 from the proximal end of theextended part 33, and the notch may be formed in thebase sheet 3 without forming theextended part 33 to form thenotch part 31. - When the cleaning
member 1 has a configuration in which thebase sheet 3 is formed with the multiple strip-like parts 32 in thesheet structure 4, it is possible to capture the dust and dirt by the strip-like parts 32 as well asfiber bundles 2, and it is possible to provide more excellent cleaning capability. In addition, since theextended part 33 forms a portion protruding outward the reach position of the fiber leading end of thefiber bundle 2, and the strip-like part 32 is formed on at least that portion in the example ofFigs. 12A and 12B , the strip-like part 32 is hardly covered with the fibers of thefiber bundles 2, and it is possible to more reliably capture the dust and dirt by the strip-like parts 32. - In the first embodiment, the cleaning
member 1 has the configuration in which the supporthandle insertion part 6 is formed by joining thesheet piece 13 and thebase sheet 3, but the cleaningmember 1 is not limited to those illustrated in such a form. - The embodiment of the invention may have a form in which the cleaning
member 1 is configured as illustrated in the example of the cleaningmember 1b ofFigs. 5A to 5C . This form is referred to a second embodiment. That is, in the second embodiment, in the cleaningmember 1, a space forming the insertion space part 7 is formed between the facingbase sheets 3 by the formation of the joining state of thebase sheets 3, as in the cleaning member 1 (1b) illustrated inFigs. 5A to 5C , and the supporthandle insertion part 6 may be formed by the insertion space part 7. In addition, the cleaningmember 1 in the second embodiment is provided with thesheet structure 4 as in the first embodiment, and each configuration such as thefiber bundle 2 and thebase sheet 3 except for the configuration in which the supporthandle insertion part 6 is formed as described above may be configured in the same manner as in the first embodiment. - The cleaning

Furthermore, thespace part 8 is formed on the outside of the supporthandle insertion part 6 at this time. In addition, thejoin portion 12 can be formed by, for example, applying an adhesive to a predetermined section to be formed thejoin portion 12, in advance to form theadhesive part 15. This is also applied to the formation of thejoin portion 12 for all embodiments of the cleaningmember 1 as well as the cleaningmember 1 ofFigs. 5A to 5C . - In addition, in the
sheet structure 4 illustrated in the example of the cleaningmember 1 inFigs. 5A to 5C , thesheet structure 4 is formed by forming a tubular body while the twopredetermined side parts raw material 9 are faced inward.
