In the cleaning tool disclosed in Patent Document 1, a long fiber bundle (tow) opened is used as a brush portion of a duster pad. Accordingly, the brush portion has a shape having a plurality of three-dimensional bending points and inflection points, and dust and dust collection performance is improved as compared with a planar shape.

The fiber bundle of the brush part is opened, but when the duster pad stored in the storage bag is taken out, the fibers are entangled and hardened, so it is necessary to loosen them by hand before use. In addition, there is a problem that fluffy fibers are caught on an uneven surface to be cleaned during use.

This invention makes it a subject to provide the cleaning tool which makes a duster pad three-dimensional and improves a collection performance by bend | folding the laminated fiber sheet to a different direction in the thickness direction.

In order to solve the above-described problems, the present invention relates to a cleaning tool including a duster pad, and a handle having a handle and an insertion portion to be inserted into the duster pad.

In the cleaning tool according to the present invention, the duster pad has a mounting surface attached to the insertion portion and a wiping surface positioned on the opposite side, and a multilayer structure in which a plurality of sheets are laminated in the thickness direction. The folding direction of at least some of the sheets facing each other in the thickness direction among the plurality of sheets is different from each other in the thickness direction.

The plurality of sheets include a first sheet stacked in the thickness direction, and a second sheet positioned on the attachment surface side of the first sheet, and the first sheet and the second sheet are Since the cross-sectional shape is folded so as to be symmetrical with each other in the thickness direction, a space can be formed between both sheets, the duster pad can be formed into a three-dimensional shape, and dust can be collected. Collecting power and cleaning efficiency are improved.

The first and second sheets are folded so that the cross-sectional shape is symmetrical with respect to a transverse center line that bisects the length of the duster pad, whereby each sheet forms a regular flange. In addition, the duster pad has a unified three-dimensional shape, and the dust collecting power and cleaning efficiency are improved.

When the first sheet and the second sheet are folded so that the cross-sectional shape is Ω, a plurality of large and small spaces can be formed between the two sheets, and the duster pad can be made three-dimensional.

At least one of the plurality of sheets is formed of a fiber nonwoven fabric perforated sheet having a large number of perforations, thereby having a cross-sectional uneven shape and scraping off dust as compared with a smooth surface. It becomes easy.

The second sheet is a composite in which a fiber sheet made of fiber nonwoven fabric and a net-like net sheet made of synthetic resin are folded, and the net sheet is exposed to the wiping surface side during cleaning. By using a net sheet, it is possible to collect relatively large trash and to wipe off dirt stuck to the surface to be cleaned.

The first sheet is formed of a hydrophilic fiber nonwoven fabric and is in a wet state impregnated with a liquid, and the first sheet hangs down when the duster pad is separated from the surface to be cleaned. Is exposed to the wiping surface side, so that dust can be wiped off with the wet first sheet, and relatively large dust is collected or stuck to the surface to be cleaned by the net sheet of the second sheet. Dirt can be scraped off.

According to the cleaning tool according to one or more embodiments of the present invention, in the plurality of layers of the sheet constituting the duster pad, at least a part of the layers facing each other in the thickness direction is bent in different directions in the thickness direction. Therefore, the duster pad has a three-dimensional shape, and the collection power and the cleaning efficiency are improved.

The laminated sheets are joined by welding means using ultrasonic processing. In addition, the

slits

27a and 28a of the first and

second attachment sheets

27 and 28 are optional, and the lengths and separation dimensions thereof can be adjusted as appropriate.

2 and 3, the brush portion 25 of the duster pad 30 is formed of a plurality of fiber sheet layers stacked in a state of being folded in the thickness direction Z, and the first layer in order from the attachment surface 31 side. 40, a second layer 50, a third layer 60, a fourth layer 70, and a fifth layer 80. The plurality of stacked layers are joined to each other by the central joining line 11. Further, the first and

second attachment sheets

27 and 28 of the attachment portion 24 and the first and

second layers

40 and 50 of the brush portion 25 are joined to each other by the side joining line 12. In the present embodiment, the brush portion 25 is formed of five layers, but may be configured with the number of layers less than or equal to that or at least 2 as long as the effects according to the present invention described later are exhibited. What is necessary is just to have a layer structure.

The first to

fifth layers

40, 50, 60, 70, and 80 constituting the brush portion 25 are hydrophobic or hydrophilic fiber nonwoven fabrics or synthetic resin sheets, preferably hydrophilic fiber sheets. As the fiber sheet, for example, various known fiber nonwoven fabrics such as spunbond fiber nonwoven fabric, air-through fiber nonwoven fabric, spunbond / meltblown / spunbond (hereinafter referred to as SMS) fiber nonwoven fabric, and spunlace fiber nonwoven fabric can be used. As a constituent material of the hydrophilic sheet, natural fibers such as cotton and pulp and cellulosic fibers such as rayon can be used in addition to the synthetic fiber subjected to the hydrophilic treatment. When the duster pad 30 is used as a wet cleaning sheet for wiping off dirt adhering to the surface to be cleaned, all the sheets constituting the brush portion 25 may be formed of a hydrophilic fiber nonwoven fabric impregnated with a liquid. preferable. The liquid impregnated in the hydrophilic fiber nonwoven fabric is a water-soluble detergent mainly composed of water, and in addition, a surfactant, a solvent, an antiseptic, a deodorant, and a fragrance may be used alone or in combination. it can. Moreover, even if it is a case where a liquid is not impregnated beforehand in a manufacturing process, the user can also impregnate a hydrophilic nonwoven fabric with water and a chemical | medical agent before use.

The sheet forming the first to

fifth layers

40, 50, 60, 70, 80 may be a perforated sheet. In such a case, each layer has a concavo-convex shape, and dust and dust collecting power is improved.

Referring to FIGS. 3 and 4 (also together with FIG. 1), the

layers

40, 50, 60, 70, 80 constituting the brush portion 25 are mutually bent in the thickness direction Z and are joined to each other at the central joining line 11. It is joined via. Each of the

layers

40, 50, 60, 70, and 80 includes a first

bent region

41, 51, 61, 71, 81 located on the front edge 30a side that is positioned symmetrically with respect to the longitudinal center line P, and a rear end. It has the

2nd bending area

42, 52, 62, 72, 82 located in the edge 30b side.

The first folding region 41 and the second folding region 42 of the first layer 40 are folded by a plurality of folding lines extending in the width direction X and spaced from each other in the length direction Y. And has a cross-sectional shape formed from two large and small Ω-shaped portions that protrude upward and overlap in the thickness direction Z. The first bent area 51 and the second bent area 52 of the second layer 50 have a plurality of flanges bent by a plurality of bent lines extending in the width direction X, and overlap in the thickness direction Z. The cross-sectional shape is composed of two large and small Ω-shaped portions projecting downward. The first folding region 61 and the second folding region 62 of the third layer 60 have a plurality of flanges bent by a plurality of folding lines extending in the width direction X, and overlap in the thickness direction Z. Thus, it has a cross-sectional shape composed of two large and small Ω-shaped portions protruding upward. The first bent area 71 and the second bent area 72 of the fourth layer 70 have a plurality of flanges bent by a plurality of bent lines extending in the width direction X, and overlap in the thickness direction X. Thus, it has a cross-sectional shape composed of two large and small Ω-shaped portions that protrude downward. The first bent area 81 and the second bent area 82 of the fifth layer 80 have a plurality of flanges bent by a plurality of bent lines extending in the width direction X, and overlap in the thickness direction Z. Thus, it has a cross-sectional shape composed of two large and small Ω-shaped portions protruding upward.

Since each

layer

40, 50, 60, 70, 80 of the brush portion 25 has such a bending mode, the directions in which the layers adjacent to each other in the thickness direction Z are folded are different from each other in the thickness direction Z. Here, “the folding directions are different from each other in the thickness direction Z” means that the first layer 40 is folded so as to protrude upward as in the present embodiment, whereas the second layer adjacent to the first layer 40 is folded. It means a mode in which the layer 50 is folded so as to protrude downward, and the layers facing each other in the thickness direction Z do not have to be folded in the same manner. For example, the first layer 40 protrudes upward. However, the second layer 50 may have a cross-sectional shape composed of two or more Ω-shaped portions that are convex downward. Of the sheets constituting the duster pad 30, the sheet (first sheet) located on the wiping surface 32 side and the sheet (second sheet) located on the attachment surface 31 side facing each other in the thickness direction Z. And the sheets located on the attachment surface 31 side and / or the wiping surface 32 side of the sheets may be flat without being folded.

In this way, each of the

layers

40, 50, 60, 70, 80 constituting the brush portion 25 folds the planar sheet so that a plurality of collars are formed, thereby generating bending points and inflection points. It is possible to improve the ability to collect garbage. Further, in each layer, the layers adjacent to each other in the thickness direction Z are not folded in the same direction in the thickness direction Z, but are folded in different directions. To S6 are formed. Specifically, the first space S <b> 1, the second bending region 42 of the first layer 40, and the second layer between the first bending region 41 of the first layer 40 and the first bending region 51 of the second layer 50. The second space S <b> 2 located between the 50 second bent areas 52, the portion of the second layer 50 between the first bent areas 51 and the second bent areas 52, and the first of the third layer 60. The third space S3 located between the bent area 61 and the portion between the second bent area 62, the first bent area 61 of the third layer 60, and the first bent area 71 of the fourth layer 70. Of the fourth space S4 located between the second folding area 62 of the third layer 60 and the second folding area 72 of the fourth layer 70 of the fourth layer 70. Between the part located between the 1st bending area 71 and the 2nd bending area 72, and the part located between the 1st bending area 81 and the 2nd bending area 82 of the 5th layer 80 The sixth spaces S6 that are positioned are defined respectively.

In this type of handy-type cleaning tool, a filament long fiber formed from a synthetic resin is used as a brush portion in order to collect the duster pad in a three-dimensional and bulky manner so as to catch up dust in as wide a range as possible. A bundle (tow) may be used. In such a case, by raising the fibers, the bulk increases and the collection area increases compared to the case where the duster pad is formed only from the fiber nonwoven fabric, but it is necessary to loosen the fibers before use to make them fluffy. There are problems such as being troublesome, and fuzzy fibers being caught on the uneven surface to be cleaned during use. According to the cleaning tool 10 according to the present embodiment, the stacked sheet-

like layers

40, 50, 60, 70, 80 are bent in different directions in the thickness direction Z, and thus are not stacked in a plane. Since the three-dimensional shape is formed and the plurality of spaces S1 to S6 are formed in the duster pad 30, the bulk of the duster pad 30 is increased and the collection area is increased. There is no problem. Therefore, according to such a bending mode, more dust can be collected by one wiping action than in the case where the duster pad 30 has a planar shape, so that the collection power and the cleaning efficiency are increased. Will improve.

In the bending mode of the duster pad 30 according to the present embodiment, the cross-sectional shapes of the

layers

40, 50, 60, 70, 80 that face each other in the thickness direction Z are symmetrical in the thickness direction Z. It is folded in. Thus, since each

layer

40,50,60,70,80 laminated | stacked is a shape from which each cross-sectional shape is folded in the mutually different direction in thickness direction Z, each layer 40, Since the plurality of

flanges

50, 60, 70, and 80 are regularly opposed to each other in the thickness direction Z, the duster is smaller than the case where the plurality of flanges irregularly face the thickness direction Z. The pad 30 can be more reliably three-dimensional.

In the bending mode of the duster pad 30 according to the present embodiment, each of the

layers

40, 50, 60, 70, 80 includes the

first bending areas

41, 51, 61, 71, 81 and the

second bending areas

42, 52, 62, 72, and 82 have cross-sectional shapes that are symmetric with respect to the transverse center line Q of the duster pad 30. In this way, each of the

layers

40, 50, 60, 70, 80 is regularly bent, whereby the first

bent areas

41, 51, 61, 71, 81 side and the second

bent areas

42, 52, There is no difference in bulk dimensions between the 62, 72, and 82 sides, and the collection area can be made constant. Each of the

layers

40, 50, 60, 70, and 80 may be folded into various known cross-sectional shapes such as a stepped shape and a pyramid shape in addition to being folded into a cross-sectional Ω shape. Furthermore, as long as the layers facing each other in the thickness direction Z are bent in different directions in the thickness direction Z, the first folding region and the second folding region are not symmetrical with respect to the transverse center line Q. It may be asymmetric or similar. Further, at least a part of the sheet layers facing each other in the thickness direction Z may be folded in different directions in the thickness direction Z.

FIG. 6B is a cross-sectional view of a duster pad according to another embodiment, and FIG. 6B is a cross-sectional view of the duster pad according to still another embodiment. 5 (a), 5 (b) and FIGS. 6 (a), 6 (b), for convenience of explanation, among the

layers

40, 50, 60, 70, 80 constituting the brush portion 25, Only the bending mode of the first layer 40 and the second layer 50 facing each other in the thickness direction Z is illustrated. However, also in these embodiments, the third to

fifth layers

60, 70, and 80 are bent in the same pattern as the bending mode of the first layer 40 and the second layer 50, and the entire brush portion 25 is bent. Is bent in different directions in the thickness direction Z.

In the embodiment shown in FIG. 5A, the first layer 40 and the second layer 50 are bent in a hierarchical shape (pyramid shape) in different directions in the thickness direction Z. In the case of such a laminated mode, the duster pad 30 can be made more three-dimensional than in the first embodiment. Further, since the vertices of the layers are opposed to each other, a relatively wide space S7, S8 is formed between the both

layers

40, 50, and relatively large dust can be collected.

In the embodiment of FIG. 5B, the first layer 40 and the second layer 50 move downward from the front edge 30a (rear edge 30b) side of the duster pad 30 toward the rear edge 30b (front edge 30a). It has a cross-sectional shape in which a plurality of flanges are stacked stepwise (or upward) downward (or upward). In the first layer 40, a plurality of flanges are stacked stepwise downward from the leading edge 30a side to the trailing edge 30b side, and in the second layer 50 facing the first layer 40, the trailing edge is formed from the leading edge 30a side. A plurality of flanges are stacked stepwise upward toward the edge 30b. Due to having such a lamination mode, a space S9 that gradually increases from the rear edge 30b side to the front edge 30a side is formed between the first layer 40 and the second layer 50.

Referring to FIG. 6A, in the present embodiment, the first layer 40 and the second layer 50 are symmetric in the thickness direction Z, but the

first folding areas

41 and 51 and the second folding are. The

areas

42 and 52 do not have a symmetric cross-sectional shape with respect to the transverse center line Q and are asymmetric. Even in such a bending mode, spaces S <b> 10 and S <b> 11 are formed between the first layer 40 and the second layer 50.

Referring to FIG. 6B, in the present embodiment, the first layer 40 and the second layer 50 have a plurality of flanges, and the opposing layers are symmetrical in the thickness direction Z. It is in the form of being folded in two. Specifically, the first layer 40 is bent in a substantially U or V cross section toward the rear end edge 30b, and the second layer 50 facing the first layer 40 has a substantially U or cross section in the direction toward the front end edge 30a. It is bent in a V shape. Spaces S12 and S13 are formed between the stacked portions of the

layers

40 and 50. In the embodiment shown in FIGS. 6A and 6B as well, the layers facing each other in the thickness direction Z are folded in different directions in the thickness direction Z, so that the duster pad 30 is three-dimensional. It can be a shape.

FIG. 9 (c) is a partially enlarged view of the region surrounded by IX (c) in FIG. 9 (a), and FIG. 10 is a state where the handle is gripped and the duster pad is separated from the floor surface. FIG. 11 is a perspective view of the cleaning tool, and FIG. 11 is a plan view of the wiping surface side when the cleaning tool is in use.

Referring to FIGS. 7 and 8, the duster pad 30 of the cleaning tool 10 according to the present embodiment has the same bending manner as that of the first embodiment, and the second layer 50 of the duster pad 30 and the second layer 50 are the same. The four layers 70 are formed from a composite composed of

fiber sheets

55 and 75, which are preferably fiber nonwoven fabrics having hydrophilicity, and net-like

net sheets

56 and 76 folded together with the

fiber sheets

55 and 75. ing. The 1st layer 40, the 3rd layer 60, and the 5th layer 80 are preferably formed from the fiber nonwoven fabric which has hydrophilicity like the

fiber sheets

55 and 75. FIG. In the following description, the second layer 50 is also referred to as a first composite layer, and the fourth layer 70 is also referred to as a second composite layer.

Referring to FIGS. 9A to 9C, the fiber sheet 55 of the first composite layer 50 is an aperture sheet having a large number of apertures 55a, and the net sheet 56 is a network having a large number of meshes 56a. It has a structure. The fiber sheet 55 has a thickness of 0.1 to 0.2 mm, and the net sheet has a thickness of 0.15 to 0.25 mm. The opening 55a of the fiber sheet 55 has an oval shape that is long in the length direction Y, and the length of the major axis is 1.0 to 2.0 mm. On the other hand, the mesh 56a of the net sheet 56 is a rhombus that is long in the width direction X, and the longer diagonal line is 3.0 to 4.0 mm, and the opening area of one opening 55a of the fiber sheet 55 is The area of one mesh is larger than that. The opening 55a formed in the fiber sheet 55 can be formed by a water jet or a needle punch. For example, when the fiber sheet 55 is manufactured by the spunlace manufacturing method, the fiber web is transported to a mesh-shaped transport belt having a large number of apertures, and fluid (water, air) is jetted from above. A large number of openings 55a can be formed. Many openings of the fiber nonwoven fabric used for each

layer

40, 60, 80 and the

fiber sheets

55, 75 are optional, and as long as dust and hair can be collected between the fibers, the openings are not formed. The surface may be smooth, the size of the openings may be different, or a plurality of recesses that do not penetrate the fiber nonwoven fabric may be formed instead of the openings. Moreover, you may use multiple things from which rigidity differs as a fiber nonwoven fabric.

In the first composite layer 50 (the second composite layer 70 has the same configuration) 50, the fiber sheet 55 and the net sheet 56 are integrally folded while being laminated with each other. The fiber sheet 55 and the net sheet 56 may be joined to each other by an adhesive or welding means in order to improve the integrity.

Since the first and second

composite layers

50 and 70 are folded in a state where the

fiber sheets

55 and 75 and the

net sheets

56 and 76 are overlapped with each other, the first, third, and fifth layers 40, The rigidity is higher than 60 and 80. Referring to FIG. 10, in the state where the user grips the handle 20 and the duster pad 30 is separated from the surface to be cleaned, the fifth layer 80 located closest to the wiping surface 32 in the brush portion 25 hangs down by its own weight. It becomes a state. On the other hand, the second composite layer 70 located on the mounting surface 31 side of the fifth layer 80 has higher rigidity than the fifth layer 80, and does not sag due to the weight of each

layer

40, 50 laminated thereon. Since it is in a stretched state, the net sheet 76 of the second composite layer 70 is exposed on the wiping surface 32 side. In the duster pad 30, the attachment portion 24, the first layer 40 and the first composite layer 50 are joined to each other by the side joining line 12, and the weight of the portion where the first composite layer 50 is laminated thereon is determined. It can be said that the second composite layer 70 is substantially loaded only with the weight of the third layer 60 laminated thereon, because the second composite layer 70 is stretched without sagging.

Referring to FIG. 11, the fifth layer 80 hangs down in the state where the duster pad 30 is lifted in this way, and the second composite layer 70 is exposed to the wiping surface 32 side, and the surface to be cleaned is left as it is. When the wiping surface 32 of the duster pad 30 is applied to the first wiping portion 87, which is located on both sides of the first wiping portion 87 and the first wiping portion 87, the first wiping portion 87 is displaced from the center portion in the width direction X. Dust can be collected by the second wiping portion 88 made of the net sheet 76 of the composite layer 70.

Here, the

net sheets

56 and 76 have higher rigidity than the fiber nonwoven fabric constituting each of the

layers

40, 60 and 80. Therefore, even when the first and second

composite layers

50 and 70 are formed only from the

net sheets

56 and 76, only the layers positioned on the wiping surface 32 side hang down, and the

net sheets

56 and 76 are The stretched state is maintained and exposed from the wiping surface 32 to the outside. Moreover, each

layer

40, 60, 80 is formed of a hydrophilic fiber nonwoven fabric and impregnated with a liquid, so that it can be more reliably suspended by its own weight.

As described above, the wiping surface 32 of the cleaning tool 10 includes the first wiping portion 87 formed from the fifth layer 80 and the second wiping portion 88 formed from the net sheet 76, so that the fifth layer 80 is formed. In a dry state, in the first wiping portion 87 formed of a fiber nonwoven fabric, relatively small dust such as dust, hair, pet hair, and the like can be collected by a large number of openings. Further, in the second wiping portion 88 formed of a synthetic resin sheet having higher rigidity than the fiber nonwoven fabric, the lint and the surface to be cleaned are stuck to each other by a large number of meshes having an area larger than the opening of the fiber sheet 75. It can be removed so as to scrape persistent dirt.

Since the second composite layer 70 forming the second wiping portion 88 has a multilayer structure folded together with the fiber sheet 75 formed of a fiber nonwoven fabric, the dust scraped off by the net sheet 76 is a fiber. Since it transfers to the sheet | seat 75 and is hold | maintained between fibers, while being excellent in retainability, a liquid stain | pollution | contamination is rapidly absorbed by the fiber sheet 75. FIG. The dust held on the fiber sheet 75 is prevented from entering between the fibers and returning to the net sheet 76 side. Moreover, when the fiber sheet 75 is in the wet state, the dirt stuck to the surface to be cleaned scraped off by the net sheet 76 can be wiped off. In addition, when the fifth layer 80 is in the wet state, dirt attached to the surface to be cleaned can be wiped off by the first wiping portion 87 in the wet state, and dust can be collected by the second wiping portion 88. Therefore, according to the situation, the portion of the wiping surface 32 that is in contact with the surface to be cleaned can be properly used while operating the handle 20 and tilting the duster pad 30.

The cleaning tool 10 is a handy type, and the duster pad 30 is tilted to wipe the floor surface quickly, or the duster pad 30 is rotated by operating the handle 20 and inserted into a relatively narrow gap, so that the entire duster pad 30 is inserted. Use it to collect dust. At that time, dust and dirt can be wiped off by the first, third and

fifth layers

40, 60, 80 in the wet state, and by the

net sheets

56, 76 of the first and second

composite layers

50, 70, The persistent dirt and relatively large dust adhering to the surface to be cleaned can be scraped off and absorbed and moved to the

fiber sheets

55 and 75 and held. Further, since each

layer

40, 50, 60, 70, 80 constituting the brush portion 25 has a plurality of collar portions, the wiping property is improved, and the opposing layers in the thickness direction Z are thicker each other. Since the three-dimensional shape is formed by being folded in different directions in the direction Z, and a plurality of spaces are formed between them, the collection area becomes larger than when each layer is planar. A lot of garbage can be collected, and cleaning efficiency improves.

When the entire surface of the duster pad 30 is pressed against the floor or tile, the side surface of the suspended fifth layer 80 comes into contact with the floor or tile first, and the position of the central joint line 11 is reached. The wiping surface 32 is exposed to the first wiping portion 87 formed by the fifth layer 80 lying down in the width direction X, falling to the one side edge 30c side or the other side edge 30d side from the center joint portion to be made The second composite layer 70 may be divided into a second wiping portion 88 formed from the net sheet 76. Even in such a case, the first wiping portion 87 and the second wiping portion 88 can collect various kinds of trash and wipe away persistent dirt.

In the thickness direction Z, the duster pad 30 is formed by alternately laminating first, third and

fifth layers

40, 60, 80 and

composite layers

50, 70 made of fiber nonwoven fabric, thereby forming a composite layer. The dust scraped off by the

net sheets

56 and 76 of the 50 and 70 can be moved and held not only in the

fiber sheets

55 and 75 but also in the

layers

40, 60 and 80 in contact therewith. However, as long as the required retainability is exhibited, the

layers

40, 60, 80 and the

composite layers

50, 70 may not be laminated alternately, and one layer is provided on the wiping surface side of the

composite layers

50, 70. As long as they are positioned, the composite layers may be laminated.

Unless otherwise specified, the members constituting the cleaning tool according to the present invention include, in addition to the materials described in the present specification, well-known materials that are commonly used in this type of field without limitation. Can be used. In addition, terms such as “first” to “ninth” used in this specification are simply used to distinguish similar elements, positions, and the like.
