Description

 Specification

 Cleaning tool and holding member constituting cleaning tool

 Technical field

 [0001] The present invention is used for wiping and cleaning dust, and includes a holding member comprising a handle member for gripping and a leg portion for holding a cleaning sheet, and an exchangeable or attached member attached to the holding member. The present invention relates to a cleaning tool composed of a disposable cleaning sheet.

 Background art

 [0002] Conventionally, twisted yarn such as cotton has been used as a cleaning tool for wiping away dust on furniture such as chiffon, electrical products such as personal computers and lighting equipment, walls, sills, and duck in the building. A hand-held mop that is used to form a brush portion and includes a holding member that holds the brush portion has been used.

 However, this type of cleaning tool cannot be used as a disposable because of its high manufacturing cost. In recent years, therefore, a disposable cleaning tool has been proposed using an inexpensive cleaning sheet for the brush part.

 [0004] As a cleaning tool in which such a brush portion is disposable, a cleaning sheet formed from a plurality of strips and fiber bundles that are elongated with a soft sheet, and a sheet for holding the cleaning sheet A cleaning tool is known which includes a bifurcated insertion portion and a holding tool including a gripping portion (see, for example, Patent Document 1).

 [0005] In the cleaning tool described in Patent Document 1, in order to hold a cleaning sheet, a base material sheet and a holding sheet are joined to each other on a top surface of the cleaning sheet by a joining line. Two parallel holding spaces that can be held by inserting a bifurcated insertion portion of the holding tool between the sheet and the holding sheet are formed. In addition, the holder has two insertion portions that are inserted into the holding space, are formed in a flat plate shape, and are arranged horizontally.

 Patent Document 1: JP 2002-369783 A

[0006] The cleaning tool described in Patent Document 1 is a flat surface formed from a sheet body as compared with a bulky mop-shaped cleaning tool in which a brush portion is formed using a conventional twisted yarn such as cotton. Since the cleaning sheet is used, cleaning is performed on the surface. Cleaning with a flat surface like this In this case, the dust is not held between the flat fibers, and only the surface of the flat sheet is used for cleaning, and the entire cleaning sheet is efficiently used for cleaning. Could not do.

 [0007] That is, it is desirable to make the fibers bulky only on the surface of the cleaning sheet so as to capture and hold the dust with the entire fiber, but use a flat cleaning sheet and a horizontal flat plate-shaped insertion portion. As long as it is, it is difficult to form a bulky like a conventional mop-shaped cleaning tool.

 [0008] The present invention has been made to solve the above-described problems, and uses a cleaning sheet as a whole to efficiently capture various kinds of dust such as dust and dirt and to provide excellent cleaning performance and It aims at providing the holding member which comprises a cleaning tool.

 Disclosure of the invention

 [0009] The present invention is a holding member that constitutes a hand-held cleaning tool by attaching and holding a disposable or replaceable cleaning tool sheet. The holding member of the present invention holds a cleaning tool sheet formed by laminating a fiber bundle or the like on the lower surface side of the base sheet to form a cleaning portion, and laminating the holding sheet on the upper surface side to form the holding portion. Used for. The holding member is provided on the rear side from the base of the two flat plate-like leg portions having a bifurcated front end side for passing through and holding the holding portion of the cleaning tool sheet. It consists of a handle member for gripping by hand. The holding member of the present invention is formed at an angle so that the inside of the two flat leg portions is high and the outside is low, the cross section in the width direction is high in the center in the width direction, and both ends are low. It is characterized in that it is formed in a so-called cross-sectional C shape.

[0010] Preferably, the holding member of the present invention is formed such that the longitudinal end portion of the leg portion is flat and has no angle, and the intermediate portion in the longitudinal direction of the leg portion is formed to have an angle. .

 [0011] In the holding member of the present invention, it is preferable that a protrusion for preventing the leg is provided on the upper surface or the lower surface of the leg portion.

 [0012] The holding member of the present invention is preferably formed of a material force in which the leg portion has elasticity.

[0013] In the cleaning tool of the present invention, a fiber bundle is laminated on one side of the base sheet, and the center of the flow direction of the fibers constituting the fiber bundle is continuously formed in the center of the base sheet Joined at the joint, and intermittently on the parallel line between the central joint and both end edges Are joined at the point-like joints that are formed on the substrate, and both ends in the fiber flow direction are not joined to the base material sheet, and the holding member is placed on the opposite surface of the base material sheet to the laminated surface of the fiber bundle. A sheet for a cleaning tool to which a holding sheet is formed which is formed by a holding part made of a space for inserting and holding the leg part, and two flat leg parts having a bifurcated front end side And a handle member that is provided rearward from the base of the leg to be gripped by hand, and is formed with an angle so that the inside of the two flat leg portions is high and the outside is low. And a holding member.

 [0014] Since the holding member of the present invention is formed at an angle so that the two flat leg portions are high on the inside and low on the outside, the conventional flat leg portions are formed horizontally. Compared to the holding member, when the cleaning tool is configured by inserting the leg into the holding part of the cleaning tool sheet and holding the cleaning tool sheet, the cleaning tool sheet follows the shape of the leg. Since it is attached to the holding member at an angle, the flat cleaning sheet constitutes the cleaning tool in a state where the center in the width direction is high and both ends are low.

 [0015] As a result, since the cleaning tool sheet attached to the holder is formed in a bulky state rather than a flat one, the entire fiber as well as the fiber surface of the cleaning sheet is used. It is possible to efficiently capture various kinds of dust such as dust and dust, and has excellent retention performance.

 [0016] In addition, the holding member of the present invention is easily inserted when the leg portion is inserted into the holding portion of the cleaning tool sheet when the tip end portion of the leg portion is formed horizontally without an angle. be able to . And since the intermediate part after inserting the tip part of the leg part is formed with an angle, the overall shape of the cleaning tool sheet is high at the center part in the width direction and low at both end parts in the width direction. As a result, the entire bulky state is maintained.

 [0017] In addition, in the holding member of the present invention, when the protrusion for preventing the leg is provided on the leg, it is difficult to remove the leg after inserting the leg into the holding part of the cleaning tool sheet. The cleaning work can be reliably performed without the sheet for the cleaning tool being easily detached from the member.

[0018] Further, in the holding member of the present invention, when the leg portion is formed of a material having elasticity, the cleaning tool can be inserted into a narrow portion. That is, in the state where the legs are inserted into the holding part of the cleaning tool sheet, the overall shape of the cleaning tool sheet is higher in the central part in the width direction. Both ends are formed low and bulky. This state force When the cleaning part side of the cleaning tool sheet of the cleaning tool is strongly pressed against the surface of the article to be cleaned, the legs that are formed at an angle are elastically distorted and deformed into a horizontal state. When the sheet has a planar shape, a state is formed in which the cleaning tool sheet and the leg portions of the holding member are thin.

 [0019] When the thickness of the cleaning portion of the cleaning tool becomes thin as described above, the cleaning tool sheet attached to the leg portion of the holding member can easily enter the narrow gap and perform cleaning. .

 [0020] Then, when the pressing of the leg portion of the cleaning tool against the article to be cleaned is restored, the leg portion returns to its original shape with an angle from the horizontal state due to its elasticity, and the bulky state of the cleaning tool is cleaned. It becomes the state of the tool.

 [0021] The cleaning tool of the present invention has a cleaning tool sheet in which fiber bundles are laminated on one side of a base sheet, and a central portion in a flow direction of fibers constituting the fiber bundle is continuous in a central portion of the base sheet. The joints are joined at the central joints formed at the same time, and are joined at the dotted joints formed intermittently on the parallel lines between the central joints and the opposite end edges. Since both ends in the direction are not joined to the base sheet, the fibers of the fiber bundle can be greatly fluffed to form a bulky portion of the fiber bundle. Fiber bundle flow in the cleaning tool sheet Both ends of the fiber hang down, and the fiber tip at both ends of the fiber moves freely away from the base sheet, so it can capture and retain various types of dust such as dust and dirt. Excellent performance.

 [0022] And the holding sheet in which the cleaning tool sheet is formed with a space for inserting and holding the leg portion of the holding member on the surface opposite to the laminated surface of the fiber bundle of the base material sheet. Since the two flat plate legs are formed at an angle so that the inside of the two flat legs is high and the outside is low, the holding member legs are used to attach the legs of the cleaning sheet. The ability to easily create a bulky and three-dimensional state by dropping the widthwise end of the fiber bundle down, especially when the fiber bundle is fluffed, just by inserting it into the holding part. it can.

In the holding member 1 shown in FIG. 1, the handle member 3 is attached to the handle member connecting portion 5 of the leg portion 2 so as to be rotatable around the support portion 4. As shown in FIG. 3, the holding member 1 has a handle member 3 that is approximately 180 downward on the rear end side (in the direction of arrow S) with the support portion 4 as the center. The holding member 1 can be rotated, and the holding member 1 can be folded in two in the longitudinal direction.

 [0025] As shown in Figs. 1 and 2, the leg 2 is arranged in parallel with two flat leg members 2R, 2L with a constant interval, and is formed as a single member at the root. .

[0026] The two leg members 2R and 2L of the holding member 1 shown in Fig. 1 are provided at the front end portion a, the intermediate portion b, and the rear end portion c. Each cross-sectional shape in the width direction is as shown in FIGS. The tip portions a of the two leg members 2R and 2L are formed in a horizontal state as shown in FIG. Further, as shown in FIG. 5, the intermediate portion b in the longitudinal direction is formed in the shape of a cross section “C” with an angle Θ so that the center side in the width direction is high and the both end sides are low. Further, as shown in FIG. 6, the rear end portion c in the longitudinal direction is formed in a horizontal state having no angle like the front end portion a.

 [0027] The leg members 2R and 2L are formed so that the angle gradually increases from the horizontal state starting from the front end portion a and the intermediate portion b. Further, the leg members 2R and 2L are formed so that the angle is horizontal between the intermediate part b and the rear end part c. That is, the intermediate part b of the leg members 2R, 2L is in a state where the central part in the longitudinal direction is most angled, and the angle gradually decreases from there toward the front end direction or the rear end direction. Is formed.

 As shown in FIG. 5, the angle Θ of the leg members 2R, 2L is preferably 10 70 °, more preferably 20-45 °. Within this range, when the leg part 2 is inserted into the holding part of the cleaning tool sheet, the insertion is easy, and it is possible to reliably hold the cleaning tool sheet in a bulky state.

 In the present invention, “front and rear” of the holding member means front and rear in the longitudinal direction, and in the holding member 1 shown in FIG. 3, the left side is the front side and the right side is the rear side. . Further, the width direction of the holding member means a short side direction, and means the left-right direction in the holding member shown in FIG.

 As shown in FIG. 11-13, the holding member 1 is provided with a convex portion 6 for preventing slipping on the upper side of the leg members 2R, 2L. The convex portions 6 are provided at five locations with a predetermined interval in the longitudinal direction of each leg member 2R, 2L. The convex portion 6 has a triangular cross-sectional shape in the longitudinal direction. However, the angle on the front end side of leg 2 is small and the angle on the rear end side is large (see Fig. 3).

Further, as shown in FIG. 7, on the back surface side of the leg members 2R and 2L, two protrusions 7 for preventing removal are provided at predetermined intervals in the middle part c of each leg member. The shape of the convex portion 7 on the back surface is the same as the convex portion 6 on the upper surface side of the leg members 2R and 2L. The angle on the end side is large. [0032] As described above, the leg members 2R, 2L are provided with the convex portions 6, 7, so that when the leg members 2R, 2L are inserted into the holding portion of the cleaning tool sheet, the convex portions are not affected by the pulling force on the holding portion. In addition to being able to insert smoothly, if it is pulled out from the holding part 22, the convex parts 6 and 7 will be caught by the sheet of the holding part, and the cleaning tool sheet 1 will come off during cleaning. Can be prevented.

 Further, as shown in FIG. 7, reinforcing ribs 9 are provided on the back surface side of the leg members 2R, 2L so as to protrude downward around the leg members 2R, 2L.

 As shown in FIG. 1, the handle member 3 of the holding member 1 of the present invention is provided with a grip portion 9 on the rear end side. The grip portion 9 is formed so as to bulge outward in the horizontal direction so that it can be easily gripped by hand. Further, the central portion of the grip portion 9 is formed as a hollow portion 10 that is thinned.

 Further, as shown in FIG. 3, the handle member 3 has a thin rear end.

 [0036] As the material of the holding member 1 of the present invention, various materials such as plastic, metal, and wood can be used. Plastic is preferable from the viewpoint of light weight and low cost. When plastic is used as a material, a polyolefin resin such as a polyethylene resin or a polypropylene resin is preferable from the viewpoint of easy molding.

 [0037] Further, the leg portion 2 of the holding member 1 is preferably formed of a material having elasticity. Here, inertia means that when the holding member 1 is held by hand and the leg part 2 is pressed against a flat place, the intermediate part b of the leg parts 2R, 2L with an angle is deformed into a horizontal state. When you remove the pressed force, it means elasticity that returns to its original shape. The material having such elasticity can be appropriately selected from polyolefin resins such as polyethylene resin and polypropylene resin, or other plastics.

 As shown in FIG. 15, the cleaning tool 11 of the present invention includes a cleaning tool sheet 20 having the holding member 1 and a holding part 22 formed so as to hold the leg part 2 of the holding member 1. Composed of

[0039] As shown in FIGS. 8 to 11, the cleaning tool sheet 20 constituting the cleaning tool 11 has a large number of fibers accumulated on one side of a rectangular base sheet 12 made of a nonwoven fabric sheet or the like. A sheet-like fiber bundle 13 is laminated, and a bag-like shape comprising a space for passing through and holding the leg portion 2 of the holding member 1 on the surface opposite to the laminated surface of the fiber bundle 13 of the base sheet 12 A holding sheet 21 on which the holding portion 22 is formed is laminated. [0040] As shown in Fig. 9 and Fig. 11, the fiber bundle 13 of the cleaning tool sheet 20 includes a fiber bundle 13a composed of fine fibers stacked on the base sheet 12 side, and an outer side of the fiber bundle 13a. It is made up of laminated thick ladies and fiber bundles 13b made of fibers. The fibers constituting the fiber bundle 13b made of thick fibers are composed of a force obtained by gathering together fibers formed by splitting a stretched polypropylene tape so as to be elongated in the stretching direction. The fiber bundle 13b composed of thick thick fibers and fibers is a central part of the base material sheet 12 having a rectangular shape in the flow direction, and is a single piece from one end edge 12c of the rectangular shape to the other end edge 12d. They are joined at the center joint 14 (see Figure 10 and Figure 11) provided on the continuous center line.

[0041] The thin fibers of the fiber bundle 13a are preferably those of 0.01 -0.05 mm. The fiber bundle 13a preferably has a fiber thickness of 11 to 18 denier. The fiber bundle 13a has a basis weight of 5-30 g / m ² when the fiber thickness is 2 denier. Further, as the thick fiber of the fiber bundle 13b, it is preferable that the fiber is thicker than the thin fiber, but a fiber having a thickness of 0.06 mm and 0.3 mm is preferable.

 [0042] The fiber bundles 13a and 13b are a collection of fibers in which a large number of fibers are arranged in the same direction, and the fibers are bundled to such an extent that the fibers do not disperse. The fiber bundles 13a and 13b are formed like a sheet and are handled as sheet-like fiber bundles. The fiber bundles 13a and 13b are, for example, natural fibers such as cotton and wool, synthetic fibers such as polyethylene, polypropylene, polyethylene terephthalate, nylon and polyacryl, composite fibers such as core-sheath fibers, sea-island fibers, and side-by-side fibers. Is used. The fibers used in the fiber bundles 13a and 13b may be those crimped by mechanical crimping, thermal crimping, or the like. Further, as the fiber bundles 13a and 13b, a long fiber bundle generally called tow, which is produced by polyethylene, polypropylene, nylon, polyester, rayon or the like, can be used.

 [0043] The thin fiber bundle 13a of the cleaning tool sheet 20 is joined at the central joint 14 and intermittently on a parallel line between both end edges 12a and 12b parallel to the central joint 14. The two ends 31a and 31b of the fiber bundle 13 in the flow direction of the fiber bundle 13 are released without being bonded to the base sheet 12 (See Figure 11). The length of the fiber bundle 13b in the fiber flow direction is the same as that of the fiber bundle 13a.

[0044] The hand-held cleaning tool sheet 20 shown in FIG. 8 to FIG. A large number of cuts 25 are formed from the parallel both end edges 12a, 12b to the vicinity of the dotted joint 17 in the same direction as the fiber flow direction of the fiber bundle 13. In the cleaning tool sheet 20, the base sheet 12, the fiber bundle 13 a, and the holding sheet 21 are formed in similar colors.

[0045] The material of the base sheet 12 constituting the cleaning tool sheet 20 is preferably a non-woven sheet having heat-sealability. The base sheet 12 preferably has a basis weight of 10 to 200 g / m ² when a nonwoven fabric is used.

 [0046] The short fiber (fiber body) constituting the nonwoven fabric sheet is preferably a heat-fusible short fiber having heat-fusibility with the fiber bundle 13. As such heat-fusible short fibers, fibers such as polypropylene, polyethylene, polyethylene terephthalate, etc., and those obtained by using sheath-core type or side-by-side type composite fibers are used.

 [0047] Examples of the nonwoven fabric sheet used as the substrate sheet 12 include spunlace nonwoven fabric, spanbond nonwoven fabric, thermal bond nonwoven fabric, air-through bond nonwoven fabric, and point bond nonwoven fabric. Preferred are spunlace nonwoven fabric and thermal bond nonwoven fabric. The nonwoven fabric sheet may be composed of a single sheet, or may be composed of a plurality of sheets of the same type or different types.

 [0048] In addition, the cleaning tool sheet 20 has a base sheet 12 and / or fiber bundles 13a and 13b to improve the ability to capture dust, such as mineral oil such as liquid paraffin, silicone oil, and nonionic surface active. You may make the oil agent containing an agent etc. adhere.

 [0049] As shown in Figs. 12 and 13, the holding sheet 21 of the cleaning tool sheet 20 is formed by laminating two non-woven fabrics 21a and 21b having heat-fusibility, and the three sides and the center excluding the insertion port 23. The seal part 28 is formed by heat-sealing the parts, and the two legs 2 of the holding member 1 are passed through and held between the two nonwoven fabrics 21a and 21b. A bag-like holding portion 22 is formed.

 [0050] The holding portion 22 is formed as two holding portions sealed in three directions excluding the opening portion as each holding portion corresponding to the size of the leg portion 2. Each holding portion may be in an open state without sealing at the tip as long as at least the side surface is sealed.

[0051] As shown in FIG. 13, the portion of the heel entrance 23 of the holding sheet 21 is composed of two nonwoven fabrics 21a, 21b They are formed in an open state without being sealed. The holding sheet 21 is formed by folding a sheet of non-woven fabric in half and heat-sealing the sealing portion 28. The upper nonwoven fabric 21a in the insertion port 23 is formed as an ear piece 29 that is not joined to the lower nonwoven fabric 21b. On the end side of the ear piece 29, a colored portion 24 serving as a mark for the insertion portion 23 is provided. When the ear piece 29 is provided, the leg portion 2 of the holding member 1 can be easily passed through.

[0052] Manufacturing of the cleaning tool sheet 20 shown in FIG. 8 to FIG. 11 is performed by first laminating a thin fiber bundle 13a on the base material sheet 12, and fusing the central joint 14 and the dotted joint 17 together. After the joining, the thick fiber bundle 13b is joined at the central joint 14. As this joining means, means such as heat fusion, ultrasonic fusion, adhesion, and adhesion are used. Further, as shown in FIG. 14, after an adhesive such as hot melt adhesive 27 is applied to the central portion of the base sheet 12 opposite to the fiber bundle 13, a holding sheet 21 is laminated, heated, pressurized, etc. The sheet 20 for the cleaning tool is obtained by joining by the above means.

 To attach the cleaning tool sheet 20 to the holding member 1 in order to configure the cleaning tool 11, the leg 2 of the holding member is inserted from the insertion opening 23 of the holding sheet 21 of the cleaning tool sheet 20. Hold it in the holding part 22.

 [0054] When the leg portion 2 is inserted into the holding portion 22, the distal end portions a of the leg members 2L and 2R are formed horizontally, so that the insertion into the holding portion 22 can be easily performed.

[0055] Then, the intermediate part b and the rear end part c of the leg part 2 are all inserted (see FIG. 15). At this time, as shown in FIG. 16, the cross-sectional shape in the middle part b of the leg part 2 corresponds to the shape of the leg part 2 so that the center side in the width direction is high and both side parts are low. It is formed in a state with an angle in the shape of a letter.

 [0056] As a result, the end of the thin fiber bundle 13a and the thick fiber bundle 13b hang down by simply holding the handle member 3 of the cleaning tool 11 with the hand so that the fiber bundle 13 side is facing down. The bundle 13b hangs down, and the fiber bundles 13a and 13b are formed to be bulky.

That is, the cleaning tool 11 shown in FIG. 15 needs to perform a special operation for raising the fiber bundle by fluffing the fibers of the fiber bundle 13b or shaking the entire cleaning tool up and down. Absent. Simply by inserting the leg part 2 of the holding member 1 into the holding part 22 of the cleaning tool sheet 20, the cleaning tool sheet that becomes the cleaning part is a mop-shaped cleaning that uses twisted yarn such as cotton. Ingredients There is an advantage that it is formed in a bulky state that is similar to the above.

 [0058] In the state shown in FIGS. 15 and 16, when the cleaning part 11 of the cleaning tool 11 and the cleaning part of the lower surface of the cleaning tool sheet 20 were strongly pressed against the surface of the article to be cleaned, they were formed with an angle. The middle part b of the leg 2 is squeezed by elasticity and easily deformed into a horizontal state without an angle, and the cleaning tool sheet 20 also has a flat shape according to the shape of the leg 2 and is used for the cleaning tool. The sheet 20 changes from a thick three-dimensional state to a thin planar shape.

[0059] When the thickness of the cleaning tool sheet 20 of the cleaning tool 11 is reduced as described above, the cleaning tool sheet 20 enters the narrow gap or the like, thereby enabling cleaning.

[0060] When the state in which the leg 2 portion of the cleaning tool 11 is pressed against the article to be cleaned is returned to the original state, the leg returns to the original shape with an angle from the horizontal state due to its elasticity, The portion of the cleaning tool sheet 20 is again formed into a bulky state.

[0061] Further, in the cleaning tool 11 shown in Fig. 15, the fibers constituting the fiber bundle 13a of the thin fibers of the cleaning tool sheet 20 are joined at the central joint 17 and the dotted joint 17, and both ends in the fiber flow direction are based. Since the fiber sheet 13 is joined to the material sheet 12, the fibers of the fiber bundle 13a can easily hang down to form a bulky portion of the fiber bundle 13a.

[0062] In addition, since both ends of the fiber bundle 13a of the cleaning tool sheet 20 in the flow direction hang down and the front end portion of the fiber is free to move from the base sheet 12, it can capture various kinds of dust such as dust and dirt. Excellent performance and retention performance.

[0063] Further, the cleaning tool sheet 20 includes the fiber bundle 13 composed of the thin fiber bundle 13a and the thick fiber bundle 13b, which is effective for cleaning the gap.

[0064] As shown in FIG. 16, since the thick fiber bundle 13b has a waist, when cleaning a thing with a thin gap such as a computer keyboard, the thin fiber does not have a waist, so it is difficult to enter the gap. Since thick fibers have waist, they can easily get into the gaps and remove dust such as dust.

 [0065] The dust thus squeezed out functions so as to be taken in by the thin fiber bundle 13a. The thick fiber bundle 13b also has a function of preventing the fibers of the thin fiber bundle 13a from being entangled with each other.

[0066] When the cleaning tool sheet 20 becomes dirty, the cleaning tool 11 removes the leg portion 2 of the holding member 1 from the throat entrance 23 of the holding sheet 21, and another cleaning tool sheet 20 that is not dirty. To replace You can.

It can be used for wiping and cleaning by contacting the surface of objects to be cleaned such as various metal products, etc., and dust and dust can be efficiently wiped and captured with a simple structure. It is extremely effective in that it can be held.
