Problems to be solved by the invention

The present invention has been made in view of the above circumstances, and an object thereof is to provide a more rational construction technique relating to a cleaning sheet and a cleaning tool.

Means for solving the problems

In order to solve the above-described problems, according to a preferred aspect of the cleaning sheet of the present invention, the cleaning sheet is used by being attached to a holder, wherein the cleaning sheet extends in a predetermined 1 st direction and a2 nd direction which is a direction intersecting the 1 st direction, and has a base portion, a fiber element, a connecting element connecting the base portion and the fiber element, a cutting element for cutting the fiber element, and a raising element formed of the fiber element cut by the cutting element. The predetermined 1 st direction is defined by the direction of movement of the holder during cleaning by the user. In this case, when the cleaning tool has a structure for rotatably holding the cleaning sheet, the direction in which the cleaning sheet is moved by the operation of the user may not be constant. In this case, each direction in which the cleaning sheet is operated by the user can be defined as the 1 st direction. In addition, for example, when the cleaning sheet extends in the longitudinal direction and in the direction intersecting the longitudinal direction, that is, in the intersecting direction, in view of the necessity of cleaning a wider range of cleaning objects, the cleaning sheet may be designed by assuming that the user moves the cleaning sheet in the intersecting direction. In this case, the crossing direction can define the 1 st direction. In this sense, the predetermined 1 st direction can be defined by a direction designed in consideration of the cleaning work performed by the user.

In addition, the base portion can preferably be constituted by a sheet-like member.

The fiber element is composed of a plurality of fiber bodies extending in the 2 nd direction. More specifically, the fiber element may be composed of tow (tow) fibers having a fiber orientation in the 2 nd direction.

The connection element is composed of a plurality of connection portions extending in the 1 st direction and formed at predetermined intervals in the 2 nd direction. More specifically, when both the base and the fiber element are made of heat-fusible fibers, the connecting element may be configured by heat-fusing both. The connecting portion may be formed by bonding the base portion and the fiber element with an adhesive.

The cutting element is composed of a plurality of cutting portions formed at predetermined intervals so as to extend in the 1 st direction. In this case, in the cleaning sheet, it can be said that the region where the cutting elements are formed constitutes the cutting element forming region, and the region where the cutting elements are not formed constitutes the cutting element non-forming region. In this case, it can be said that the cut element non-formation region constitutes a non-cut fiber element. The non-staple fiber element is composed of a plurality of non-staple fiber portions, and the non-staple fiber portions extending in the 2 nd direction constitute the 2 nd-direction non-staple fiber portion row region.

The raising element is composed of a plurality of raising portions formed of fiber bodies cut by the cutting portion. That is, the raised portion is formed by separating the end portion of the cut fibrous body from the connecting portion. The raising element constitutes a1 st-direction raising portion row region formed by connecting the cut portions adjacent to each other in the 1 st direction. Typically, the 1 st direction raised part row region is constituted by raised parts of the common connecting part. Further, the 1 st direction raised part row region may be defined by a region in which raised parts and non-staple fiber parts adjacent in the 1 st direction are alternately continuous.

The cleaning sheet further has end regions including ends in the 1 st direction and extending in the 2 nd direction and a central region extending in the 2 nd direction. When the cleaning sheet is attached to a holder having a cleaning head for attaching the cleaning sheet, an end portion of the cleaning sheet in the 1 st direction may be folded back with respect to a cleaning surface of the cleaning head and positioned on a surface of the cleaning head opposite to the cleaning surface. In this case, the end region is defined by a range from the end in the 1 st direction of the cleaning sheet to at least the raised part including the end in the 1 st direction closest to the cleaning sheet. Further, the central region is defined by a range extending in the 2 nd direction and passing through the center point of the cleaning sheet.

In the 1 st direction raised part row region, the raised parts of the end regions constitute a plurality of fiber raised parts having a larger number of fiber bodies than the raised parts of the central region. In addition, the majority of the fiber raised portions are formed to have a longer extension length in the 2 nd direction than the raised portions in the central region. Therefore, it can be said that the majority of the fiber raised portions constitute the 2 nd-direction long-distance raised portions as compared with the raised portions in the central region.

When the cleaning object is a floor, there are substances having a relatively long extension length such as hair and lint, substances having a relatively large volume such as cotton wool and bread crumbs, and substances having a relatively small volume such as silica sand, as dirt present on the floor.

In the cleaning operation, the raised portions in the end regions are first brought into contact with dirt. In this case, since the raised portions in the end regions constitute a large number of fiber raised portions, the above-described dust having a relatively long extension length and dust having a relatively large volume can be captured. In this case, the dust and dirt not captured by the plurality of fiber raising portions is captured by the raising portions formed in the central region.

As described above, according to the cleaning sheet of the present invention, dust can be efficiently captured on the cleaning surface of the cleaning sheet.

According to another aspect of the cleaning sheet of the present invention, the raised portions in the central region can constitute a small number of raised portions of fibers having a smaller number of fiber bodies than the raised portions in the end regions. In addition, the raised portions of the fibers in a small number have a shorter extension length in the 2 nd direction than the raised portions in the central region. Thus, it can be said that the small number of fiber raised portions constitute the 2 nd direction short distance raised portions.

By adopting the cleaning sheet of the technical scheme of the invention, dust and dirt which are not captured by a plurality of fiber raising parts can be captured by a plurality of fiber raising parts.

According to another aspect of the cleaning sheet of the present invention, the cut portion in the end region can constitute a long-distance cut portion having a length in the 1 st direction longer than that of the cut portion in the central region.

The cleaning sheet according to the aspect of the present invention can form a large number of fiber raised portions by cutting the fiber body at the long-distance cutting portion.

According to another aspect of the cleaning sheet of the present invention, the cut portion in the central region may constitute a short-distance cut portion having a shorter length in the 1 st direction than the cut portion in the end region.

With the cleaning sheet according to the present invention, the short-distance cutting section cuts the fibrous body, thereby forming a small number of fiber raising sections.

According to another aspect of the cleaning sheet of the present invention, the raised portion has an open end and a connecting end connected to the connecting portion, and is configured by the open end being separated from the base portion.

In the cleaning sheet according to the aspect of the present invention, when the user moves the cleaning sheet while the cleaning sheet is in contact with the object to be cleaned, the fiber body of the raised portion moves so that the open end portion faces in the direction opposite to the moving direction. The cleaning object can be efficiently cleaned according to the behavior of the raised part.

According to another aspect of the cleaning sheet of the present invention, the cleaning sheet may have a raising element non-forming region and a raising element forming region in which a raising element is formed. The non-raising element-forming region can be said to be constituted by the non-staple fiber portion described above.

With the cleaning sheet according to the aspect of the present invention, the non-raising element-forming region is brought into contact with the cleaning object, whereby dust and dirt can be captured even in the non-raising element-forming region.

According to another aspect of the cleaning sheet of the present invention, the raised element forming region may have a2 nd direction raised part row region formed by a plurality of raised parts extending in the 2 nd direction. Further, the raising element non-formation region may have a2 nd direction non-raising portion row region extending along the 2 nd direction. The 2 nd direction non-raised part row region can be said to be constituted by the above 2 nd direction non-staple fiber part row region.

In the 1 st direction, the 2 nd direction raised part row regions and the 2 nd direction non-raised part row regions may be alternately arranged. In this case, the 2 nd direction raised part row region composed of the large number of raised parts is longer in the 1 st direction than the 2 nd direction raised part row region composed of the small number of raised parts.

In another aspect of the cleaning sheet of the present invention, the plurality of 2 nd direction non-raised part row regions may be configured to have the same length in the 1 st direction. In this case, it is sufficient that the lengths in the 1 st direction are the same to mean "the same" in the design process of the cleaning sheet. Further, it is sufficient that not "identical" but "substantially identical".

In the cleaning sheet according to the aspect of the present invention, the arrangement ratio of the 2 nd direction non-raised part row region per unit area in the central region of the cleaning sheet is larger than that in the end region. As described above, during the cleaning operation, the fibrous body of the raised portion moves with the connecting end portion as a fulcrum. At this time, the fibrous body of the raised part may enter between the 2 nd direction non-raised part row region and the cleaning target. In this case, more fibrous bodies enter between the cleaning target and the 2 nd direction non-raised part row region in the central region of the cleaning sheet than the end regions. Therefore, when the user performs the cleaning operation, the central region can form a long-distance thickness region in which the length of the central region in the thickness direction is longer than the length of the end regions in the thickness direction. On the other hand, the end region can form a short-distance thickness region whose length in the thickness direction of the end region is shorter than that of the central region. According to this configuration, since the movement of the dust can be facilitated from the end region to the central region, the cleaning surface of the cleaning sheet can be used more efficiently.

According to another aspect of the cleaning sheet of the present invention, the pocket element can be formed by a space formed between the raised portion and the base portion. The bag element is formed by a region surrounded by the pair of connecting portions and the pair of 2 nd-direction non-raised portion row regions.

According to another aspect of the cleaning sheet of the present invention, the pocket element may be constituted by a plurality of pocket portions.

The cleaning sheet adopting the technical scheme of the invention can enable a plurality of bag parts to capture dust and dirt, thereby improving the cleaning efficiency.

According to another aspect of the cleaning sheet of the present invention, the pocket portion in the end region can constitute a long-distance pocket portion having a length in the 1 st direction longer than the pocket portion in the central region.

The cleaning sheet according to the present invention can efficiently contain dirt collected by a large number of fiber raising portions in a long-distance bag portion.

According to another aspect of the cleaning sheet of the present invention, the pocket portion in the central region can be a short-distance pocket portion having a shorter length in the 1 st direction than the pocket portion in the end region.

By adopting the cleaning sheet of the technical scheme of the invention, dust and dirt collected by a small number of fiber fluffing parts can be efficiently stored in the short-distance bag part.

According to another aspect of the cleaning sheet of the present invention, the fiber element may be formed of tow fibers. In this case, the fibers constituting the tow fibers constitute the fiber body.

The cleaning sheet according to the aspect of the present invention can be easily manufactured by using tow fibers.

According to another aspect of the cleaning sheet of the present invention, the connecting element can be configured by thermally welding the base and the fiber element.

The cleaning sheet according to the aspect of the present invention can reliably and quickly form a plurality of connecting portions, and therefore, the manufacturing efficiency of the cleaning sheet can be improved.

According to another aspect of the cleaning sheet of the present invention, the fiber elements can be disposed on both surfaces of the base portion.

With the cleaning sheet according to the present invention, when the cleaning operation is completed on one surface, the user can perform the cleaning operation on the other surface. Therefore, a cleaning sheet having excellent cost effect for the user can be constructed.

In order to solve the above-described problems, the cleaning tool may be constituted by the cleaning sheet and the holder. In this case, the holder includes a head portion against which the cleaning sheet is brought into contact, a holding portion provided in the head portion and holding the cleaning sheet, and a grip portion to be gripped by a user.

According to the present invention, a more rational construction technique relating to a cleaning sheet and a cleaning tool can be provided.

A cleaning sheet and a cleaning tool according to an embodiment of the present invention will be described with reference to fig. 1 to 15. First, a structure of a cleaning tool a as one embodiment of the "cleaning tool" of the present invention will be described. Examples of the cleaning object to be cleaned by using the cleaning tool a include indoor, outdoor, and outdoor surfaces to be cleaned (floor surfaces, wall surfaces, windows, ceiling surfaces, outer wall surfaces, furniture surfaces, clothes, curtains, bedding, lighting, home appliances, and the like) of individual houses, apartments, buildings, factories, vehicles, and the like. These various surfaces to be cleaned may be formed as a flat surface, or may be formed as a curved surface, a concave-convex surface, or a stepped surface.

The cleaning tool a of the present invention includes a holder 200 and a cleaning element 100 attached to the holder 200 for use. The holding tool has a different structure depending on the surface to be cleaned. In the embodiment of the present invention, a holder 200 particularly suitable for cleaning floor surfaces will be described. The cleaning element 100 may be a disposable cleaning element or a cleaning element that can be repeatedly used by washing or the like. Hereinafter, the disposable cleaning element will be described.

The cleaning tool a is an example of the "cleaning tool" of the present invention, the holding tool 200 is an example of the "holding tool" of the present invention, and the cleaning element 100 is an example of the "cleaning sheet" of the present invention.

(Structure of holding tool)

As shown in fig. 1, the cleaning tool a is composed of a holder 200 and a cleaning element 100. The holder 200 is configured to detachably hold the cleaning element 100. The holding tool 200 according to the embodiment of the present invention can be used as appropriate for various holding tools proposed for cleaning floor surfaces.

As shown in fig. 1, the holding tool 200 includes a grip portion 210 to be gripped by a user, a tube portion 250 extending from the grip portion 210, a head portion 220, and a coupling portion 260 coupling the tube portion 250 and the head portion 220. The tube portion 250 is formed in an elongated shape by connecting a plurality of tube members. The coupling portion 260 is formed to allow the head 220 to rotate with respect to the tube portion 250 (the grip portion 210).

The grip 210 is an example of the "grip" of the present invention, and the head 220 is an example of the "head" of the present invention.

As shown in fig. 1, the head 220 has a1 st head face 220Z1 facing the user when the user cleans the floor face. The head 220 has a2 nd head face 220Z2 which is a face opposite to the 1 st head face 220Z 1. The 2 nd head surface 220Z2 is a surface facing the floor when the user cleans the floor.

As shown in fig. 1, the 1 st head face 220Z1 includes a holding portion 230 for holding the cleaning element 100. As described above, the structure of the holding portion 230 can be appropriately selected from various structures of such holding portions. For example, the holding portion 230 may be formed of a plate-shaped member formed of synthetic resin having elasticity and a slit provided in the plate-shaped member. In this case, the user can fix the cleaning element 100 and the holder 200 by pushing the cleaning element 100 into the slit. The holding portion 230 detachably holds the cleaning element 100.

The holding portion 230 is an example of the "holding portion" of the present invention.

As shown in fig. 1, the 2 nd head surface 220Z2 forms a contact portion 240, and the cleaning element 100 attached to the holding portion 230 contacts the contact portion 240. The structure of the abutting portion 240 can be appropriately selected from various structures of such abutting portions. For example, the contact portion 240 may be formed of a foamed body made of a synthetic resin having elasticity. Further, the surface of the abutting portion 240 may be formed with irregularities.

The contact portion 240 is an example of the "contact portion" of the present invention.

(Structure of cleaning body)

The structure of the cleaning element 100 will be described with reference to fig. 2 to 12. Fig. 2 is a plan view schematically showing the cleaning element 100.

As shown in fig. 2, the cleaning element 100 is a sheet-like member extending in a longitudinal direction Y, a cross direction X intersecting the longitudinal direction Y, and a thickness direction Z intersecting both the longitudinal direction Y and the cross direction X. The cleaning element 100 is designed on the assumption that the user reciprocates the cleaning element 100 in the intersecting direction X. The cleaning element 100 has an end 100X in the cross direction X and an end 100Y in the longitudinal direction Y.

The cross direction X is an example of the "1 st direction" of the present invention, the longitudinal direction Y is an example of the "2 nd direction" of the present invention, and the end 100X is an example of the "1 st direction" of the present invention.

The cleaning element 100 has a1 st surface 100Z1 and a2 nd surface 100Z2 which is a surface facing the 1 st surface 100Z 1.

Fig. 3 is an exploded view showing the structure of the cleaning element 100. As shown in fig. 3, the cleaning element 100 includes a base portion 110, a fiber element 120, and a side sheet portion 180. The base 110 is an example of the "base" of the present invention, and the fiber element 120 is an example of the "fiber element" of the present invention. The fiber elements 120 are provided on the 1 st surface 100Z1 side and the 2 nd surface 100Z2 side, respectively, and the side piece portions 180 are provided on the 1 st surface 100Z1 side and the 2 nd surface 100Z2 side, respectively. The side sheet portion 180 is joined to the fiber element 120 and the base portion 110 in a region including the end portion 100X in the intersecting direction X of the fiber element 120 and the base portion 110. That is, the end portion 100X in the intersecting direction X of the base portion 110 and the fiber element 120 is sandwiched between the side piece portion 180 on the 1 st surface 100Z1 side and the side piece portion 180 on the 2 nd surface 100Z2 side, respectively. The base portion 110 and the side panel portion 180 are joined by heat-welding predetermined regions.

As shown in fig. 1, when the cleaning element 100 is attached to the head portion 220 of the holder 200, the region having the side sheet portions 180 is folded back toward the 1 st head face 220Z 1. The "folded region" of the cleaning element 100 is a region that does not contact the contact portion 240 of the head portion 220. A part of the side piece portion 180 folded back to the 1 st head face 220Z1 is fixed to the holding portion 230 of the holding tool 200.

As shown in fig. 2, the base 110 and the fiber element 120 are connected by a connecting element 130 extending in the intersecting direction X. The connection element 130 is composed of a plurality of connection portions 131. The connection element 130 is formed by thermally welding predetermined regions of the base 110 and the fiber element 120. The connection element 130 is an example of the "connection element" of the present invention, and the connection portion 131 is an example of the "connection portion" of the present invention. The connection portion 131 has a region having a predetermined inclination angle with respect to a center line 100yc (see fig. 10) of the cleaning element 100 extending in the longitudinal direction Y.

In the present embodiment, "a component or the like extends in the intersecting direction X (longitudinal direction Y)" means that the component or the like is parallel to the intersecting direction X (longitudinal direction Y), and that the extending direction of the component or the like has an intersecting direction X component. In particular, as shown in fig. 2, in the present embodiment, the connecting element 130 (raising portion 131), the cutting element 140 (cutting portion 141), the raising element 150 (raising portion 151), and the pocket element 160 (pocket portion 161) are arranged to extend at a predetermined angle with respect to both the crossing direction X and the longitudinal direction Y. In this case, these components may be said to extend in the intersecting direction X (longitudinal direction Y). Further, since the connecting element 130 (raising portion 131), the cutting element 140 (cutting portion 141), the raising element 150 (raising portion 151), and the pocket element 160 (pocket portion 161) extend at a predetermined angle with respect to both the intersecting direction X and the longitudinal direction Y, these constituent elements can have both the length in the intersecting direction X and the length in the longitudinal direction Y.

The fibrous element 120 is formed of an aggregate of fibrous bodies 121 having a fiber orientation in the longitudinal direction Y. The fibrous body 121 is an example of the "fibrous body" of the present invention. The fiber body 121 is a thermoplastic fiber, and a core-sheath composite fiber in which a core portion is formed of Polyester (PET) and a sheath portion is formed of Polyethylene (PE) is used in the present invention. The fiber elements 120 are typically obtained by opening tow fibers.

A dust and oil cleaning agent (not shown) is applied to the base 110 and the fiber element 120. Any dust-absorbing oil can be used. In the cleaning element 100 according to the embodiment of the present invention, liquid paraffin is used as the dust-collecting oil agent.

As shown in fig. 2, a cutting element 140 extending in the intersecting direction X is formed between the pair of connecting portions 131. The fiber element 120 cut by the cutting element 140 forms a raising element 150 and a bag element 160. The cutting element 140 is an example of the "cutting element" of the present invention, the raising element 150 is an example of the "raising element" of the present invention, and the bag element 160 is an example of the "bag element" of the present invention.

The cutting element 140 is configured by a plurality of cutting portions 141 arranged continuously at predetermined intervals so as to extend in the intersecting direction X. The cutting section 141 is an example of the "cutting section" of the present invention.

Fig. 4 is an enlarged view of the region I shown in fig. 2, and is an explanatory view showing the cut portion 141, the raised portion 151, and the bag portion 161.

As shown in fig. 4, the cut portion 141 forms the raised portion 151 and the pocket portion 161. The raising portion 151 is an example of the "raising portion" of the present invention, and the bag portion 161 is an example of the "bag portion" of the present invention. The raising element 150 is constituted by a plurality of raising portions 151, and the pocket element 160 is constituted by a plurality of pocket portions 161.

In addition, the region of the fiber element 120 where the cutting element 140 is formed forms a cutting element forming region. The cut element forming region constitutes a raising element forming region and a pocket element forming region.

In addition, the region of the fiber element 120 where the cut element 140 is not formed constitutes the non-cut fiber element 170. The non-staple fiber element 170 may be referred to as a staple element non-forming region 146, a raising element non-forming region 156, or a bag element non-forming region 166. The non-staple fiber element 170 is composed of a plurality of non-staple fiber portions 171. The non-staple fiber portion 171 may be referred to as a region where the fiber body 121 extends between the pair of connection portions 131. The raising element non-formation region 156 is an example of the "raising element non-formation region" of the present invention.

As shown in fig. 5, the raised portion 151 is formed by the fibrous body 121 cut by the cutting portion 141. The raised portion 151 has a connecting end portion 151a and an open end portion 151b connected to the connecting portion 131, and is configured by the open end portion 151b being separated from the base portion 110. The connection end 151a is an example of the "connection end" of the present invention, and the open end 151b is an example of the "open end" of the present invention.

Further, as shown in fig. 5, the pocket 161 is formed by a space formed between the raised part 151 and the base 110. The raised portions 151 are formed by the open end portions 151b of the plurality of fibrous bodies 121 being separated from the base portion 110. In this case, the raised portions 151 are formed as long as at least a part of the open end portions 151b of the fibrous bodies 121 are separated from the base portion 110. That is, when the raised portions 151 are formed, it is not necessary that the open end portions 151b of all the fibrous bodies 121 be separated from the base portion 110. In this sense, the pocket 161 is formed by the space formed between the raised part 151 and the base part 110, but even if the fibrous body 121 that can constitute the raised part 151 exists in this "space", it can be defined as the "space" that can constitute the pocket 161. In this sense, the bag portion 161 can be said to be formed by a region surrounded by the pair of connecting portions 131 and the pair of non-staple fiber portions 171.

As shown in fig. 6, the intersecting direction cutting portion row region 141X is formed by the adjacent cutting portions 141 extending in the intersecting direction X being continuous. The intersecting direction cut portion row region 141x is formed by the intersecting direction raising portion row region 151x and the intersecting direction pocket portion row region 161 x. The intersecting direction cutting portion row region 141x is configured to pass through a center line between the pair of connection portions 131. Two raised portions 151 are formed between the pair of connecting portions 131, and the fiber bodies 121 in the longitudinal direction Y of the two raised portions 151 have substantially the same length. The non-cut fiber portions 171 extending in the intersecting direction X and adjoining each other are continuous to form an intersecting-direction non-cut fiber portion row region 171X.

As shown in fig. 7, the longitudinal direction cut portion row region 141Y is formed by the continuous cut portions 141 extending in the longitudinal direction Y and adjoining each other. The longitudinal raising portion row region 151y and the longitudinal pocket portion row region 161y are formed along with the longitudinal cutting portion row region 141 y. Further, a lengthwise non-cut fiber array region 171y is formed between the pair of lengthwise cut portion array regions 141y (the lengthwise raised portion array region 151y, the lengthwise pocket portion array region 161y) in the intersecting direction X. The longitudinal raised part row region 151y is an example of the "2 nd direction raised part row region" of the present invention, and the longitudinal non-staple fiber part row region 171y is an example of the "2 nd direction non-raised part row region" of the present invention.

Fig. 8 is a sectional view taken along line II-II in fig. 2, and is an explanatory diagram showing the structure of the longitudinal cut portion row area 141 y. For convenience of explanation, fig. 8 does not show the structure of the 2 nd surface 100Z 2. As shown in fig. 8, a plurality of cutting portions 141 are arranged in the longitudinal cutting portion row region 141Y continuously in the longitudinal direction Y. When the longitudinal cut portion row region 141Y is considered as the longitudinal raised portion row region 151Y, it can be said that a plurality of raised portions 151 are continuously arranged in the longitudinal direction Y in the longitudinal raised portion row region 151Y. When the longitudinal direction cut portion row region 141Y is considered as the longitudinal direction bag portion row region 161Y, it can be said that a plurality of bag portions 161 are continuously arranged in the longitudinal direction Y in the longitudinal direction bag portion row region 161Y.

Fig. 9 is a cross-sectional view taken along line III-III in fig. 2, and is an explanatory diagram showing the structure of the longitudinal non-staple fiber portion row region 171 y. For convenience of explanation, fig. 9 does not show the structure of the 2 nd surface 100Z 2. As shown in fig. 9, a plurality of non-cut fiber portions 171 are arranged in the longitudinal direction Y continuously in the longitudinal non-cut fiber portion row region 171Y.

As shown in fig. 10, the cleaning element 100 has an end region 101e including an end 100X in the intersecting direction X and extending in the longitudinal direction Y. The end region 101e is defined by a range including the end 100X and the cut portion 141 closest to the end 100X. In this sense, the end region 101e can be said to be defined by a range including the end portion 100X and the raised part 151 closest to the end portion 100X. The end region 101e can be said to be defined by a range including the end 100X and the bag portion 161 closest to the end 100X. The end region 101e is an example of the "end region" of the present invention.

As shown in fig. 10, the cleaning element 100 has a center line 100yc extending in the longitudinal direction Y. The cleaning element 100 also has a central region 101c that includes a center line 100yc and extends in the longitudinal direction Y. The central region 101c is defined by a range including the center line 100yc and the cut portion 141 closest to the center line 100 yc. In this sense, the central region 101c can be said to be defined by a range including the center line 100yc and the raised part 151 closest to the center line 100 yc. The central region 101c can be said to be defined by a range including the center line 100yc and the bag portion 161 closest to the center line 100 yc. The central region 101c is an example of the "central region" of the present invention.

Further, an intermediate region 101m extending in the longitudinal direction Y is formed between the end region 101e and the central region 101 c.

As shown in fig. 11, the length D1 in the intersecting direction X of the cut portions 141 of the end region 101e is formed longer than the length D3 in the intersecting direction X of the cut portions 141 of the central region 101 c. The length D2 in the intersecting direction X of the cut portion 141 of the intermediate region 101m is shorter than the length D1 and longer than the length D3.

According to this structure, the cut portion 141 of the end region 101e forms the long-distance cut portion 142. The long-distance cut portions 142 make the number of the raised portions 151 of the end regions 101e larger than the number of the raised portions 151 of the central region 101c, and thus the fiber bodies 121 are formed. According to this structure, the raised portions 151 of the end regions 101e form a large number of fiber raised portions 152. Further, the long-distance cut portion 142 makes the length of the pocket 161 in the end region 101e longer in the cross direction X than the pocket 161 in the central region 101 c. According to this structure, the pocket 161 of the end region 101e forms the long-distance pocket 162.

The long-distance cut portion 142 is an example of the "long-distance cut portion" of the present invention, the majority fiber raising portion 152 is an example of the "majority fiber raising portion" of the present invention, and the long-distance bag portion 162 is an example of the "long-distance bag portion" of the present invention.

The cut portion 141 of the end region 101e forms a long-distance cut portion 142, the raised portion 151 forms a large-number fiber raised portion 152, the pocket portion 161 forms a long-distance pocket portion 162, and along with this, the cut portion 141 of the central region 101c forms a short-distance cut portion 144, the raised portion 151 forms a small-number fiber raised portion 154, and the pocket portion 161 forms a short-distance pocket portion 164. The cut portion 141 of the middle region 101m forms an intermediate cut portion 143, the raised portion 151 forms an intermediate fiber raised portion 153, and the pocket portion 161 forms an intermediate pocket portion 163. The short-distance cut section 144 is an example of the "short-distance cut section" of the present invention, the small-number fiber raising section 154 is an example of the "small-number fiber raising section" of the present invention, and the short-distance bag section 164 is an example of the "short-distance bag section" of the present invention.

According to this configuration, in the intersecting direction cutting part row region 141X (see fig. 6), the distance in the intersecting direction X of the cutting parts 141 can be said to be gradually shortened from the end region 101e toward the central region 101 c. In the cross-direction raised part row region 151x, the number of the fibrous bodies 121 of the raised parts 151 can be said to be gradually reduced from the end regions 101e toward the central region 101 c. In the intersecting direction bag row region 161X, the distance in the intersecting direction X of the bag 161 can be said to be gradually shorter from the end region 101e toward the center region 101 c.

As shown in fig. 12, the length D4 of the non-staple fiber portion 171 in the cross direction X is the same in each of the end region 101e, the intermediate region 101m, and the central region 101 c. Therefore, the proportion of the non-staple fiber portion 171 per unit area is smaller in the end region 101e than in the central region 101 c.

Next, the operation of the cleaning tool a of the present invention will be described with reference to fig. 13 to 15. Fig. 13 is an explanatory diagram showing the operation of the raising portion 151, the bag portion 161, and the non-staple fiber portion 171 extending in the cross direction X. In addition, the connection portion 131 is omitted in fig. 13 for convenience. Fig. 14 is an explanatory diagram showing the lengths of the large number fiber raised portions 152, the middle number fiber raised portions 153, and the small number fiber raised portions 154 in the longitudinal direction Y.

As shown in fig. 13, the user moves the cleaning element 100 in the intersecting direction X while holding the grip portion 210 with the cleaning element 100 attached to the head portion 220.

As shown in fig. 14, in the longitudinal direction Y, the length 152Y of the majority fiber raised portions 152 is longer than the length 153Y of the middle number fiber raised portions 153 and the length 154Y of the minority fiber raised portions 154. In this sense, the raised portions 151 of the end regions 101e can be said to constitute long-length direction long-distance raised portions having a length 152Y in the length direction Y longer than a length 154Y in the length direction Y of the raised portions 151 of the central region 101c, and the raised portions 151 of the central region 101c can be said to constitute short-length direction short-distance raised portions.

Further, as for the cut portions 141, it can be said that the cut portions 141 of the end region 101e constitute long-distance longitudinal cut portions whose length 142Y in the longitudinal direction Y is longer than the length 144Y in the longitudinal direction Y of the cut portions 141 of the central region 101c, and that the cut portions 141 of the central region 101c constitute short-distance longitudinal cut portions. It can be said that the length 143Y in the longitudinal direction Y of the cut portion 141 of the intermediate region 101m is shorter than the length 142Y and longer than the length 144Y.

Further, with respect to the pocket 161, it can be said that the pocket 161 of the end region 101e constitutes a lengthwise long-distance pocket whose length 162Y in the lengthwise direction Y is longer than the length 164Y in the lengthwise direction Y of the pocket 161 of the central region 101c, and that the pocket 161 of the central region 101c constitutes a lengthwise short-distance pocket. It can be said that the length 163Y in the longitudinal direction Y of the pocket 161 in the intermediate region 101m is shorter than the length 162Y and longer than the length 164Y.

In the cleaning operation, since the majority of the fiber raising portions 152 are first brought into contact with the dust, the majority of the fiber raising portions 152 can capture the dust having a relatively long extension length and the dust having a relatively large volume. The grime not captured by the plurality of fiber raising portions 152 is captured by the middle number of fiber raising portions 153, and the grime not captured by the middle number of fiber raising portions 153 is captured by the small number of fiber raising portions 154. Through this cleaning process, dust having a relatively small volume can be captured by the small number of fiber raising portions 154.

Here, the operation of the bag 161 will be described. Since the long-distance bag 162 is first in contact with the dirt, the long-distance bag 162 can receive the dirt having a relatively long extension length and the dirt having a relatively large volume. Dirt not captured by the long-distance bag 162 is stored in the middle-distance bag 163, and dirt not stored in the middle-distance bag 163 is stored in the short-distance bag 164.

As described above, the cleaning tool a of the present embodiment can efficiently clean dirt having different extension lengths and volumes.

As described above, the cleaning element 100 has a larger proportion of the arrangement of the lengthwise non-cut fiber array regions 171y per unit area in the central region 101c than in the proportion of the arrangement of the lengthwise non-cut fiber array regions 171y per unit area in the end regions 101 e. During the cleaning operation, the fibrous body 121 of the raised portion 151 moves with the connecting end portion 151a as a fulcrum. At this time, the fibrous body 121 of the raised part 151 may enter between the longitudinal non-cut fiber array region 171y and the cleaning object. In this state, more fibrous bodies 121 enter between the longitudinal non-cut fiber array region 171y of the central region 101c and the cleaning target than the end region 101 e. Therefore, when the user performs the cleaning operation, the long-distance thickness region 102Z3 having a longer distance in the thickness direction Z than the end region 101e can be formed in the central region 101 c. On the other hand, the end region 101e can form a short-distance thickness region 102Z1 having a shorter distance than the central region 101c in the thickness direction Z. In addition, the intermediate region 101m can form an intermediate distance thickness region 102Z2 in the thickness direction Z.

According to this configuration, since the movement of the dirt from the end region 101e to the central region 101c can be facilitated, the cleaning surface of the cleaning element 100 can be used more efficiently.

The cleaning element 100 and the cleaning tool a of the present invention are not limited to the configurations described in the above embodiments, and other configurations may be used.
