However, in the cleaning article described in Patent Document 2, since the fiber layer is configured to be bonded to the base sheet by a plurality of continuous seal wires, the fiber layer is raised and the fiber layer is compressed and recovered during cleaning. The properties are not excellent. Therefore, the followability to the uneven surface of the cleaning object is low, and the cleaning performance is not excellent.
On the other hand, in the cleaning article described in Patent Document 3, since the fiber layer is only on one side and can be cleaned only on one side, the cleaning work is complicated and the convenience is not fully considered.

  Therefore, the object of the present invention is that the fiber layer is highly raised and the fiber layer is highly compressible and recoverable at the time of cleaning. The object is to provide an excellent cleaning article.

  The present invention is a cleaning article having a flat cylindrical handle insertion portion, which can be attached by inserting a handle into the handle insertion portion, wherein the handle insertion portion is formed with an opposing handle insertion portion. The sheet is formed by bonding, and at least one fiber layer made of a fiber bundle is provided on each of the upper surface and the lower surface of the handle insertion portion of the handle insertion portion forming sheet. The first fiber layer on the handle insertion part forming sheet side is joined to the handle insertion part forming sheet by a central continuous seal line that extends continuously in the longitudinal direction at the center in the width direction. The object is achieved by providing a cleaning article joined by a side non-continuous seal extending discontinuously in the longitudinal direction at a position spaced at least one side outside in the width direction. It is.

  According to the cleaning article of the present invention, at the time of cleaning, the raising property of the fiber layer and the compression recovery property of the fiber layer are excellent, the followability to the uneven surface of the object to be cleaned is high, and the fiber tip contributing to cleaning is used for cleaning. Since the entire surface of the article is covered, the cleaning performance is excellent. In addition, convenience is sufficiently taken into consideration, and in cleaning a narrow gap or the like, cleaning on both sides is also possible.

Hereinafter, the cleaning article of the present invention will be described based on a preferred embodiment thereof with reference to the drawings.
As shown in FIGS. 1 to 4, the cleaning article 10 of the present embodiment is vertically long and has a flat shape as a whole, and includes a pair of flat cylindrical handle insertion portions 15 and 15 in the width direction. Yes. In the cleaning article 10 of the present embodiment, a pair of insertion portions 22 and 22 (details will be described later) in the handle 20 can be inserted into and attached to the pair of handle insertion portions 15 and 15, respectively.
In the following description, “longitudinal direction” and “width direction” mean the longitudinal direction (insertion direction) and the width direction of the handle insertion portion 15 unless otherwise specified.

The handle insertion portion 15 is formed by joining two opposite handle insertion portion forming sheets 13 and 13 with a center continuous seal line 16A and a side discontinuous seal 16B (details will be described later) at predetermined positions.
One or more fiber layers 11 each comprising a fiber bundle are provided on the upper and lower surfaces of the handle insertion portion 15 in the handle insertion portion forming sheet 13. In the present embodiment, two fiber layers 11 of a first fiber layer 11A and a second fiber layer 11B are provided on the upper surface and the lower surface of the handle insertion portion 15, respectively. Note that the expression “fiber layer 11” is used in the description common to the first fiber layer 11A and the second fiber layer 11B.

  11 A of 1st fiber layers are the fiber layers by the side of the handle insertion part formation sheet 13 most among the fiber layers 11, and the 2nd fiber layer 11B is a fiber layer of the outer side of 11 A of 1st fiber layers. Therefore, in the cleaning article 10 of the present embodiment, the second fiber layer 11B and the first fiber layer 11A on the upper surface of the handle insertion portion 15 and the first fiber layer on the lower surface of the handle insertion portion 15 from the upper layer toward the lower layer. Four fiber layers laminated in the order of 11A and second fiber layer 11B are formed.

  The fiber layer 11 is formed by orienting a fiber bundle with a predetermined thickness. The fiber bundle is substantially oriented in the width direction of the handle insertion portion 15. Therefore, the first fiber layer 11 </ b> A and the second fiber layer 11 </ b> B are laminated so that the fiber orientation direction is substantially orthogonal to the longitudinal direction of the handle insertion portion forming sheet 13. Each fiber layer 11 has a substantially rectangular shape in plan view, and is substantially the same shape.

The fiber length of the fiber bundle constituting the fiber layer 11 is preferably 30 to 150 mm, more preferably 50 to 120 mm, from the viewpoint of dust entanglement. In the present embodiment, fibers having such a fiber length are used in a fiber bundle (tow) state. In that case, it is preferable to sufficiently open the fibers using a known opening device.
The thickness of the fiber is not particularly critical, but is preferably 0.1 to 200 dtex, particularly 2 to 30 dtex, from the viewpoints of dust entanglement and prevention of scratches on the surface to be cleaned.

It is preferable to use crimped fibers as the fibers constituting the fiber layer 11 because dust entanglement is further improved. As the crimped fiber, a two-dimensional or three-dimensional crimped fiber can be used. The crimp rate (JIS L0208) is preferably 5 to 50%, particularly preferably 10 to 30%, from the viewpoint of improving dust entanglement. The crimp rate is defined as a percentage of the difference between the length A when the fiber is stretched and the length B of the original fiber to the length A when the fiber is stretched, and is calculated from the following equation: .
Crimp rate = (A−B) / A × 100 (%)

The length B of the original fiber means a length obtained by connecting both ends of the fiber with a straight line when the fiber is in a natural state. The natural state means a state in which one end of the fiber is fixed to a horizontal plate and hung downward by its own weight. The length A when the fiber is stretched means the length at the minimum load when the fiber is stretched until there is no crimp.
The crimp rate of the fiber is as described above, and the number of crimps is preferably 2 to 10 per cm.

  The handle insertion portion forming sheet 13 has a substantially rectangular shape, and the longitudinal direction thereof coincides with the longitudinal direction of the cleaning article 10. The length of the handle insertion portion forming sheet 13 is substantially the same as the length of the fiber layer 11. The width of the handle insertion portion forming sheet 13 is narrower than the width of the fiber layer 11.

The handle insertion portion forming sheet 13 has flexibility in the longitudinal direction, and is easy to follow along the surface to be cleaned. Therefore, since the fiber layer 11 joined to the handle insertion portion forming sheet 13 can easily follow along the surface to be cleaned, the effect of capturing dust, dust, etc. by the cleaning article 10 is enhanced.
As a forming material of the handle insertion portion forming sheet 13, a fiber sheet such as a nonwoven fabric used in a conventional cleaning article can be used. In particular, an air-through nonwoven fabric or a spunbonded nonwoven fabric is preferable.

The fiber layer 11 and the handle insertion portion forming sheet 13 are joined along the longitudinal direction of the handle insertion portion forming sheet 13 with their center portions in the width direction being matched.
Specifically, the first fiber layer 11A is joined to the handle insertion portion forming sheet 13 by a central continuous seal line 16A that extends continuously in the longitudinal direction at the central portion in the width direction. At positions spaced apart outward in the direction, they are joined by side non-continuous seals 16B extending discontinuously in the longitudinal direction.
Further, the second fiber layer 11B is joined to the handle insertion part forming sheet 13 only at the center part in the width direction by the center continuous seal line 16A.

In the cleaning article 10 of the present embodiment, the center continuous seal line 16A located in the center in the width direction is a continuous straight line and extends between the longitudinal front and rear ends of the handle insertion portion forming sheet 13. Is formed. The width direction position of the center continuous seal line 16A is also the width direction center portion of the handle insertion portion forming sheet 13.
In order for the tip of the fiber that contributes to cleaning to extend over the entire surface of the cleaning article, the width direction position of the central continuous seal line 16A divides the width direction of the handle insertion portion forming sheet 13 into 2: 8 to 8: 2. The position is preferably a position where the width direction is divided into 4: 6 to 6: 4.

  The length of at least one of the handle insertion portion forming sheet 13 is 100% or more of the length along the insertion direction of the handle insertion portion 15 of the first fiber layer 11A or the second fiber layer 11B. It is preferable that both the handle insertion part forming sheets 13 are longer than the first fiber layer 11A or the second fiber layer 11B from the viewpoint of easy confirmation of the insertion position of the handle 20, ease of insertion operation, and the like. The longitudinal end portion of the handle insertion portion forming sheet 13 preferably extends from 1 mm to 40 mm from the longitudinal end portion of the first fiber layer 11A or the second fiber layer 11B, and preferably extends from 1 mm to 30 mm. Further preferred.

Further, when cleaning is performed by holding the handle 20 like the cleaning article 10, only the tip portion of the cleaning article 10 tends to become dirty. Considering this tendency, from the viewpoint of making it possible to use the cleaning surface without waste, it is possible to insert the handle 20 from the side opposite to the insertion direction of the handle 20 shown in FIG. It is also effective to provide two insertion openings. The cleaning article 10 of this embodiment has such a form as will be described later. Also in this case, similarly to the above, the longitudinal end portion of the handle insertion portion forming sheet 13 extends from the longitudinal end portion of the first fiber layer 11A or the second fiber layer 11B on the other insertion port side. It is preferable.

The handle insertion portion forming sheet 13 preferably has an unjoined portion of at least 1 mm or more in the portion extending from the first fiber layer 11A or the second fiber layer 11B in order to improve wearability. . More preferably, it has an unjoined portion of 5 mm or more.

Side discontinuous seals 16B and 16B (portions surrounded by broken lines in FIG. 3) are respectively provided outside the center continuous seal line 16A in the width direction.
The side non-continuous seal 16B is composed of an assembly of 2 to 100 point seals 18 spaced in the longitudinal direction. The number of point seals 18 constituting the assembly is more preferably 2 to 50. The point seal 18 of this embodiment is formed from a circular heat seal. The point seals 18 are arranged so that the positions in the longitudinal direction coincide with each other, and are formed at equal intervals in the longitudinal direction. From the viewpoint of preventing the point seal 18 from being caught when the handle 20 is inserted into the handle insertion portion 15, the interval in the longitudinal direction of the point seal 18 is preferably 5 to 40 mm.

The width direction interval W1 between the center continuous seal line 16A and the side non-continuous seal 16B is preferably 5 to 90 mm, more preferably 5 to 45 mm.
The width-direction interval W1 is the width of the inner edge in the width direction of the point seal 18 forming the side non-continuous seal 16B and the width of the center continuous seal line 16A in the state where the opposing handle insertion portion forming sheets 13 overlap. This is the distance measured along the width direction of the handle insertion portion forming sheet 13 between the outer edge in the direction. In the present embodiment, the width direction interval W <b> 1 is the width of the handle insertion portion 15.

  The total seal length of the side non-continuous seal 16B (the length when the non-continuous portion of the side non-continuous seal is virtually packed and regarded as a continuous line) is the length along the handle insertion portion 15 of the first fiber layer 11A. It is preferably 10% or more, and more preferably 15% or more. Further, the total seal length of the side non-continuous seal 16B is preferably 10% or more of the length along the insertion direction of the handle insertion portion 15 of the center continuous seal line 16A, and more preferably 15% or more.

In the region between the point seals 18 adjacent to each other in the longitudinal direction in the side non-continuous seal 16B, between the handle insertion portion forming sheet 13 and the first fiber layer 11A and between the opposing handle insertion portion forming sheets 13. (Details will be described later) are not joined.
In addition, the shape of the point seal | sticker 18 may be an ellipse, a rectangle, etc., for example. The intervals in the longitudinal direction of the point seals 18 may not be equal.

  Therefore, in the longitudinal sectional view along the width direction, the first fiber layer 11A is joined at three locations of the center continuous seal line 16A and the two side non-continuous seals 16B as shown in FIG. Or, as shown in FIG. 4 (b), it is joined at only one location of the central continuous seal line 16A. As shown in FIG. 4A and FIG. 4B, the second fiber layer 11B is joined at only one central continuous seal line 16A in any cross section as shown in FIGS. 4 (a) and 4 (b) in the longitudinal sectional view along the width direction. .

  As described above, in the present embodiment, the first fiber layer 11A, the second fiber layer 11B, and the handle insertion portion forming sheet 13 are bonded to each other according to the fiber layers 11A, 11B. ing. As a result, the raised state of the fiber bundle (tow) differs depending on each of the fiber layers 11A and 11B even at the same seal point (central continuous seal line 16A) in the central portion in the width direction. The first fiber layer 11A has a tendency to rise vertically due to the presence of the second fiber layer 11B, and rises obliquely upward. On the other hand, the second fiber layer 11B is assisted by the tendency to stand up vertically by the fact that the first fiber layer 11A is immediately adjacent (details will be described later).

  These effects can also be realized by simply increasing the amount of fiber bundles used in one layer, regardless of the use of the sealing positions by the respective fiber layers 11A and 11B. However, such a method (form) tends to increase costs. Furthermore, the reliability of joining (seal) of the fiber bundle is lowered, and the fiber is likely to drop off frequently. From the viewpoint of avoiding these problems, it is preferable to properly use the bonding method using the fiber layers 11A and 11B described in the present embodiment. Each of the fiber layers referred to here may be one obtained by dividing a bundle of layers as appropriate, or may be distinguishable in the thickness direction.

  The center continuous seal line 16A and the side non-continuous seal 16B are formed by known joining means such as heat sealing and adhesive bonding. When the handle insertion portion forming sheet 13 is made of a heat-fusible material, the center continuous seal line 16A and the side non-continuous seal 16B can be formed by heat fusion.

  A pair of flat tubular inserts 15 and 15 are formed by joining opposite handle insert forming sheets 13 and 13 with three side non-continuous seals 16B, a central continuous seal line 16A, and a side non-continuous seal 16B. Is formed. That is, the three side non-continuous seals 16B, the center continuous seal line 16A, and the side non-continuous seals 16B include a joint seal portion between the handle insertion portion forming sheet 13 and the fiber layer 11, and the opposite handle insertion portion forming sheet 13, It also serves as a joint seal part between 13 members.

  The handle insertion portion 15 is formed over the entire length between the front and rear end portions in the longitudinal direction of the handle insertion portion forming sheet 13. In the handle insertion portions 15 and 15, when the handle 20 is not inserted, the opposed handle insertion portion forming sheets 13 and 13 are in contact with each other. However, when the handle 20 is inserted, the opposed handle is formed. The insertion portion forming sheets 13 and 13 are separated from each other to form a cylindrical space.

  The handle insertion portion 15 has an insertion port at each of the longitudinal front and rear end portions of the handle insertion portion forming sheet 13. Therefore, the handle 20 can be inserted into the handle insertion portion 15 from any insertion port.

  As shown in FIG. 5, the handle 20 includes a gripping portion 21 and a pair of insertion portions 22, 22 that are bifurcated from the tip of the gripping portion 21. The grip portion 21 and the insertion portion 22 form a predetermined angle. The insertion part 22 has an elongated flat plate shape. Since the insertion portion 22 has such a shape, flexibility is imparted to the insertion portion 22. When flexibility is given, when the surface to be cleaned having a curved surface or unevenness is cleaned, the cleaning article 10 easily follows the surface to be cleaned, which is advantageous from the viewpoint of increasing dust removal efficiency.

  The pair of insertion portions 22 can be inserted into the pair of handle insertion portions 15 in the cleaning article 10, respectively. A hook portion 23 having a shorter length than the insertion portion 22 is provided between the insertion portions 22 and 22. The hook portion 23 has its tip turned upward at a predetermined angle. The hook portion 23 is detached from the cleaning article 10 by engaging with a notch 19 (details will be described later) in the cleaning article 10 in a state where the insertion section 22 is inserted into the handle insertion section 15. It is difficult.

  As a material for forming the handle 20, a thermoplastic resin is preferable. Specifically, polyethylene, polypropylene, polyvinyl chloride, polystyrene, ABS resin, acrylic resin, and the like are preferable from the viewpoint of molding processability and flexibility.

The cleaning article 10 of this embodiment is used for cleaning in a state where the pair of insertion portions 22 and 22 in the handle 20 are inserted and fixed to the pair of handle insertion portions 15 and 15, respectively.
The width of the handle insertion portion 15 is set to be approximately the same as the width of the insertion portion 22 of the handle 20 from the viewpoint of allowing the handle 20 to easily enter the handle insertion portion 15 and not easily coming off from the handle insertion portion 15 during cleaning. Is preferred. In a state where the pair of insertion portions 22 and 22 of the handle 20 are respectively inserted into the pair of handle insertion portions 15 and 15 of the cleaning article 10, the handle insertion portion 15 corresponds to the thickness of the insertion portion 22 in the width direction. The insertion part 22 is tightened.

The front and rear end portions in the longitudinal direction of the handle insertion portion forming sheet 13 are folded outward toward the central portion in the longitudinal direction, and the central portion in the width direction of the folded portion is gripped by a central continuous seal line 16A. The insertion portion forming sheet 13 is joined.
A notch 19 is provided at the front and rear end portions in the longitudinal direction of the handle insertion portion forming sheet 13 as an engaging means for engaging with the hook portion 23 of the handle 20.

  The notch 19 has a U-shape and is opened upward from the inside in the longitudinal direction of the handle insertion portion forming sheet 13 when the hook portion 23 is engaged. When the notch 19 is engaged with the hook portion 23, the handle 20 is restricted from moving in the longitudinal direction of the handle insertion portion 15, particularly to the outside in the longitudinal direction, so that the inserted handle 20 is removed from the cleaning article 10. It is designed to be fixed stably.

Since the notch 19 is formed in both of the opposing handle insertion portion forming sheets 13, the handle 20 can be inserted into the handle insertion portion regardless of whether the hook portion 23 is disposed on the upper surface side or the lower surface side of the cleaning article 10. 15 and can be fixed.
In this embodiment, the length of the handle insertion portion 15 is substantially the same as the length of the fiber layer 11 (the length along the insertion direction of the handle insertion portion 15). In consideration of wearability and the like, it is preferable that the length of the handle insertion portion forming sheet 13 is longer than the length of the fiber layer 11 and the length of the handle insertion portion 15 is longer than the length of the fiber layer 11. Yes (not shown).

  As shown in FIG. 6, the cleaning article of the present invention may fluff the fibers of each fiber layer 11. When the whole fiber of each fiber layer 11 is fluffed, the entire shape of the cleaning article 10 becomes a substantially columnar shape, and the effective area of the fiber layer 11 (contact area with the object to be cleaned) increases, and its collection effect. Will improve. In order to make the fiber layer 11 fluffy, for example, it is preferable to blow air on the fiber layer 11 to make the fiber bundle fluffy.

  According to the cleaning article 10 of the present embodiment configured as described above, the first fiber layer 11 closest to the handle insertion portion forming sheet 13 among the fiber layers 11 is located at the center in the width direction on the handle insertion portion forming sheet 13. Are joined by a central continuous seal line 16A that extends continuously in the longitudinal direction, and the side discontinuous seals that discontinuously extend in the longitudinal direction at positions spaced outward from the central continuous seal line 16A in the width direction. It is joined by 16B.

  Therefore, the first fiber layer 11A joined to the handle insertion part forming sheet 13 only at the central continuous seal line 16A forms a brush with a fiber bundle (tow) on the lower side of the center part in the width direction of the cleaning article 10. Is done. However, on the outside of the first fiber layer 11A, there is a second fiber layer 11B joined to the handle insertion part forming sheet 13 only by the central continuous seal line 16A, and the first fiber layer 11A rises vertically. Hindering. The first fiber layer 11 </ b> A itself is also an aggregate of fibers, and the fibers close to the seal in the thickness direction tend to rise vertically when viewed from the handle insertion portion forming sheet 13. Also, fibers that are away from the seal tend to rise at an angle of less than 90 degrees depending on the distance.

  On the other hand, also in the 1st fiber layer 11A joined to the handle insertion part formation sheet 13 with the center continuous seal line 16A and the side discontinuous seal 16B, the brush of the vicinity of the width direction edge part of the cleaning article 10 is formed. Here again, each fiber has a different tendency to rise depending on the arrangement position in the thickness direction. The fiber far from the handle insertion portion forming sheet 13 rises vertically because there are few other fibers that hinder vertical rise and there are more other fibers that hinder the tendency to fall down. On the other hand, the fibers close to the handle insertion portion forming sheet 13 tend to fall asleep (fall down). Due to the difference in the tendency of each of these fibers to rise, a brush with a fiber bundle (tow) is formed so as to cover the vicinity of the seal also in this portion.

  Further, the second fiber layer 11B joined to the handle insertion portion forming sheet 13 only by the center continuous seal line 16A forms a brush with a fiber bundle (tow) on the upper side of the widthwise center portion of the cleaning article 10. . This is because the second fiber layer 11B falls from the vertical state by the first fiber layer 11A joined to the handle insertion portion forming sheet 13 only by the central continuous seal line 16A inside the second fiber layer 11B. It is hindered. The second fiber layer 11B itself is also an aggregate of fibers, and the fibers close to the seal in the thickness direction tend to rise vertically when viewed from the handle insertion portion forming sheet 13, and the fibers away from the seal are There is a tendency to stand up at an angle of less than 90 degrees depending on the distance. As described above, the brush formed only by each seal portion can be formed by a plurality of continuous seal lines. However, such brushes tend to fall down in the same direction as the fibers that prevent them from falling down after being loaded during use, after use, etc. Recovery is not expected.

However, as in the cleaning article of the present invention, when there are a plurality of fiber sealing positions and a plurality of patterns of brushes are formed, the patterns supporting the raised fibers are different for each brush, and the raised fibers Are effectively supported, and a cleaning article having different napping directions is formed. This tendency works effectively even after a load is applied during use, after use, etc., and exhibits a certain level of compression recovery. This effect covers the entire surface of the cleaning article so that the brush on the surface is effective for the cleaning operation. Further, the fibers rise up by air blow or the like and are in a form of supporting each other. As shown in FIG. 6, it is possible to form the cleaning article 10 so that the entire circumference is covered with the tips of the brushes of the fibers.
In the present embodiment, these effects are combined, and at the time of cleaning, the raising property of the fiber layer 11 and the compression recovery property of the fiber layer 11 are excellent, the followability to the uneven surface of the cleaning object is high, and the cleaning performance is excellent. ing.

  Next, the cleaning article 10 according to the second embodiment of the present invention will be described with reference to FIGS. 7 and 8. Regarding the second embodiment, the description in detail regarding the first embodiment is applied as appropriate to points that are not particularly described. Moreover, in FIG.7 and FIG.8, the same code | symbol is attached | subjected to the same member as FIGS.

  As shown in FIGS. 7 and 8, the cleaning article 10 of the second embodiment is provided with only one handle insertion portion 15. Two identical and vertically long handle insertion portion forming sheets 13 and 13 are bonded together by two side non-continuous seals 16B and 16B extending in the longitudinal direction to form a cylindrical handle insertion portion 15. As shown in FIG. 8, each of the two side non-continuous seals 16B and 16B (portion surrounded by a dotted line in FIG. 8) has a point seal 18 formed by a circular heat seal in the longitudinal direction of the sheets 13 and 13, etc. It is formed side by side at intervals. The center continuous sealing line 16A by linear heat sealing provided in the cleaning article of the first embodiment joins the handle insertion portion forming sheet 13 and the fiber layer 11, but inserts two grips. The part forming sheets 13 are not joined to each other.

  In the present embodiment, the shape of the insertion portion of the handle 20 may be bifurcated as in the first embodiment as long as the width thereof is substantially the same as that of the handle insertion portion 15. It may be an integral shape (not shown) that is not branched.

  According to the second embodiment, the same effect as the first embodiment can be obtained. Further, when the insertion portion of the handle 20 has an integral shape that is not branched into two forks, the rigidity of the insertion portion is enhanced by the handle 20, so The operability is improved when cleaning gaps between furniture or the like, or when scraping and removing dust stuck to the surface to be cleaned.

The cleaning article of the present invention is not limited to the embodiment described above, and can be appropriately changed without departing from the spirit of the present invention.
The fiber layer 11 may be provided in the handle insertion part forming sheet 13 only in one layer (that is, only the first fiber layer 11A). Three or more fiber layers 11 can be provided.
The handle insertion portion 15 may be formed by joining one handle insertion portion forming sheet 13 folded in the width direction at a predetermined position.

The point seals 18 and 18 constituting the pair of side non-continuous seals 16B and 16B can be arranged with their longitudinal positions shifted. In such a form, as shown in FIG. 9, the first fiber layer 11 </ b> A includes a central continuous seal line 16 </ b> A and one side non-continuous seal 16 </ b> B (point seal 18) in the longitudinal sectional view along the width direction. It also has a cross-sectional shape joined at a location.
The side non-continuous seal 16B can be provided only at a position spaced from the central continuous seal line 16A to one side outside in the width direction.

  Three or more handle insertion portions 15 may be provided in one cleaning article 10 as long as the insertion portion 22 in the handle 20 can be inserted. There is no restriction | limiting in the form of the handle 20, either.
