Summary of the Invention

Problems to be Solved by the Invention

[0004] According to the cleaning tool disclosed in Patent Document 1, by pulling out the cleaning sheet from the outlet of the drum and cutting it along the cutting position display line printed on the cleaning sheet, one round of the cleaning sheet can be accurately cut, so it can be used without waste.

[0005] However, cutting the cleaning sheet after cleaning is troublesome, and there is also a risk that dust adheres to the cleaning adhesive surface of the roll-shaped cleaning sheet and becomes unhygienic even when the cleaning tool is being stored.

[0006] On the other hand, in order to eliminate such trouble and unhygienic conditions, it is also conceivable to attach the cleaning sheets one by one to the cleaning tool for use. However, it is troublesome to perform the attachment operation to the cleaning tool without grasping and bending the cleaning sheet made of thin paper, and when the entire cleaning sheet is adhered to the cleaning tool body, it can be said that it is difficult to remove it from the cleaning tool body after use.

[0007] An object of the present invention is an improvement over the prior art, and relates to providing a cleaning sheet that is excellent in terms of hygiene when used one by one, and that can easily perform the operations of attaching and detaching to and from a cleaning tool.

Embodiments for Carrying Out the Invention

[0012] Referring to the attached Figs. 1 - 8, the details of the cleaning tool 1 according to the present invention will be described as follows. In addition, the following embodiments include the essential requirements that cannot be lacking in the present invention, and in addition, the requirements that can be selectively adopted and can be appropriately combined.

[0013] Referring to FIGS. 1 to 3, the cleaning tool 1 is a so-called adhesive type cleaning tool, and includes a hand-held cleaning tool body 2 and a cleaning unit 3 including a cleaning sheet 10 attached to the cleaning tool body 2.

[0014] The cleaning tool body 2 is made of hard plastic or metal, and includes a handle 4, a support portion 5 that bends from the lower end of the handle 4 and extends downward, and a roller (moving body) 6 that is rotatably supported by the support portion 5 and extends in a direction orthogonal to the handle 4.

[0015] The cleaning unit 3 includes a cleaning sheet 10 having a longitudinal direction Y and a width direction X that intersect each other and having an adhesive area 50 described later, and a backing sheet 20 that covers the cleaning sheet 10. The cleaning sheet 10 has a first surface 10a exposed to the outside and a second surface 10b facing the backing sheet, and is fixed to the backing sheet 20 via the adhesive surface described later located on the second surface 10b.

[0016] The backing sheet 20 is formed of cardboard, and preferably, a release agent is applied to the surface to which the cleaning sheet 10 is adhered.

[0017] Examples of the base material sheet forming the cleaning sheet 10 include woven fabrics, knitted fabrics, non-woven fabrics, etc. made of chemical fibers, natural fibers, etc.

[0018] Preferred materials include non-woven fabrics. Specific examples of non-woven fabrics include spunlace non-woven fabrics, needle-punched non-woven fabrics, chemical bond non-woven fabrics, air-through non-woven fabrics and those by the card method such as point bond non-woven fabrics, those by the airlaid method such as airlaid non-woven fabrics, those by the direct method such as spunbond non-woven fabrics and meltblown non-woven fabrics, and those by wet papermaking, etc., but are not limited thereto.

[0019] Examples of the fibers of the base sheet include synthetic fibers such as polyester, nylon, polypropylene, polyethylene, acrylic, vinylon, and polyurethane, semi-synthetic fibers such as acetate, regenerated fibers such as rayon, inorganic fibers such as glass, metal, and carbon, and natural fibers such as cotton, hemp, wool, and silk. Synthetic fibers are preferred, and polyester, polypropylene, polyethylene, nylon, and acrylic are particularly preferred.

[0020] The backing sheet 20 is rectangular, has first and second end edges 21, 22 that are spaced apart and opposed to each other in the longitudinal direction Y and extend linearly in the width direction X, and first and second side edges 23, 24 that are spaced apart and opposed to each other in the width direction X and extend linearly in the longitudinal direction Y.

[0021] The cleaning sheet 10 is flat, has a transverse center line Q that bisects the dimension in the width direction X, first and second end edges 11, 12 that are spaced apart and opposed to each other in the longitudinal direction Y, and first and second side edges 13, 14 that are spaced apart and opposed to each other in the width direction X. The first and second end edges 11, 12 of the cleaning sheet 10 are opposed to the first and second end edges 21, 22 of the backing sheet 20, and the first and second side edges 13, 14 are opposed to the first and second side edges 23, 24 of the backing sheet 20.

[0022] The cleaning sheet 10 further has a slit 15 that extends inward in the width direction X from the second side edge 14. On the first surface 10a of the cleaning sheet 10, a first display mark 18 consisting of an arrow mark pointing to the first end edge 11 side is arranged. Referring to FIG. 2, on the backing sheet 20, a mark 25 consisting of a punch hole for allowing the user to recognize the slit 15 of the cleaning sheet 10 is located.

[0023] The first end edge 11 has a shape that protrudes outward in the width direction X and consists of a portion that extends obliquely toward the transverse center line Q, and the leading edge 11a intersects the transverse center line Q. The second end edge 12 extends linearly in the width direction X, the first and second side edges 13, 14 extend linearly in the longitudinal direction Y, and the second side edge 14 has a dimension in the longitudinal direction Y that is larger than that of the first side edge 13.

[0024] The cleaning sheet 10 has a first region 31 located on the second edge 12 side and a second region 32 that gradually tapers outward in the longitudinal direction Y from the first region 31. Specifically, the first region 31 is a region in the width direction X from the second edge 12 to the bent portion where the first side edge 13 and the first edge 11 intersect, and the second region 32 is a region from the bent portion to the tip edge 11a. The second region 32 has an asymmetric shape with respect to the transverse center line Q.

[0025] Regarding the dimensions of the backing sheet 20, the dimension in the longitudinal direction Y (the dimension of the backing sheet 20 in the longitudinal direction Y) L1 is 300 to 400 mm, and the dimension in the width direction X (the dimension of the backing sheet 20 in the width direction X) W1 is 200 to 300 mm. Also, the separation dimension R1 in the longitudinal direction Y between the second edge 22 of the backing sheet 20 and the second edge 12 of the cleaning sheet 10 is 55 to 70 mm.

[0026] As long as the cleaning sheet 10 is sized to be affixed within the backing sheet 20 as shown in the illustrated embodiment, appropriate outer dimensions can be adopted. For example, the dimension in the longitudinal direction Y (the dimension in the longitudinal direction of the second side edge) L2 of the cleaning sheet 10 is 225 mm, the dimension in the width direction X (the dimension in the width direction X of the second edge 12) W2 is 160 mm, and the dimension in the longitudinal direction Y of the first side edge 11 is L3 is 145 mm. Also, the separation dimension W3 in the width direction X between the second side edge 14 and the tip edge 11a of the first edge 11 is 80 mm, the dimension in the longitudinal direction from the first side edge to the tip edge 11a is W4 is 80 mm, the dimension in the longitudinal direction from the second side edge 14 to the tip edge 11a is L4 is 40 mm, and the separation dimension L5 in the length direction L from the bent portion where the second side edge 14 and the first edge 11 intersect to the slit 15 is 145 mm.

[0027] Referring to FIG. 4, the cleaning sheet 10 has a coating area 40 on the first surface 10a where the base sheet is resin-coated. The coating area 40 is located within the first area 31, and a non-coating area where no resin coating is applied is formed between the coating area 40 and the second edge 12, and the second area 32 is also not resin-coated. However, if necessary, the second area 32 may also be resin-coated.

[0028] The resin coating is, for example, a fluororesin coating using Teflon (registered trademark), and can impart non-stickiness (a property of low wettability to repel adhesives).

[0029] Referring to FIG. 5, the cleaning sheet 10 has an adhesive area 50 on the second surface 10b where an adhesive is applied. The adhesive area 50 is rectangular and located within the first area 31, and is spaced apart from the outer peripheral edge of the cleaning sheet 10. For example, the separation dimension in the width direction X between the first and second side edges 13, 14 of the cleaning sheet 10 and the adhesive area 50 is 2 mm, and the separation dimension in the longitudinal direction Y between the second edge 12 and the adhesive area 50 is 5 mm.

[0030] The adhesive area 50 has a function of catching dust on the surface to be cleaned and a function of holding the cleaning sheet 10 in a state where it is wound around the roller 6. On the second surface 10b of the cleaning sheet 10, a second display mark 19 formed by a line extending in the longitudinal direction Y is printed at the tip of the second area 32.

[0031] <Method of attaching the cleaning sheet> Referring to FIGS. 6(a) and 6(b), first, the cleaning unit 3 is placed on a placement surface such as a table or the floor so that the surface of the cleaning sheet 10 attached to the backing paper 20 faces upward. Next, while the user holds down the second edge 22 side with the left hand, the user picks up the tip of the second area 32 with the right hand and bends it along the virtual folding line 60 toward the first surface 10a side of the first area 31. The virtual folding line 60 is located on the second edge 22 side of the backing paper 20 rather than at the boundary between the first and second areas 31, 32.

[0032] At this time, alignment is performed so that the display mark 19 located on the second surface 10b side of the cleaning sheet 10 coincides with the display mark 18 located on the first surface 10a side in the longitudinal direction Y and is in a state of being continuous with each other. In this way, by folding the second area 32 onto the first area 31, an overlapping portion is formed, and a part of the adhesive area 50 located on the second surface 10b side is exposed.

[0033] Referring to FIGS. 7(a) and (b), next, the handle 4 of the cleaning tool body 2 is grasped, and the roller 6 is pressed against the overlapping portion of the cleaning sheet 10. In that state, the roller 6 is rolled toward the first edge 21 side of the backing sheet 20 until it moves to the first edge 21 side of the backing sheet 20 beyond the bent portion where the virtual bending line 60 is located.

[0034] By rolling until it exceeds the bent portion, the cleaning sheet 10 can be fixed to the roller 6 through the exposed adhesive area 50. Although the adhesive area 50 can be surely fixed to the roller 6 by the roller 6 rolling beyond the bent portion, the user cannot sufficiently visually recognize it by the operation at hand.

[0035] However, since a slight step is formed in the bent portion, even if the user does not visually recognize it, the user can also confirm by feeling that the roller 6 has exceeded the bent portion by the slight vibration called "katan" when the roller 6 in the hand exceeds the step, even without visual recognition.

[0036] From that state, by reversing the roller 6 and rolling it toward the second edge 22 side of the backing sheet 20, the cleaning sheet 10 is wound around the roller 6, the adhesive area 50 located on the second surface 10b side of the cleaning sheet 10 is completely peeled off from the backing sheet 20, and the cleaning sheet 10 is wound around the roller 6 to be in a use state of the cleaning tool 1.

[0037] At this time, as described above, it is preferable that the release agent is applied to the mount 20. By applying the release agent also to the region of the separation dimension R1 in the longitudinal direction Y between the second edge 22 of the mount 20 and the second edge 12 of the cleaning sheet 10 (see FIG. 2), while strongly pressing against the mount 20 and maintaining the wound state of the cleaning sheet 10, it can be easily peeled off.

[0038] Further, in a state where the cleaning sheet 10 is attached, the adhesive region 50 is fixed to the non - coating region 41 (see FIG. 4) located on the second edge 12 side. Thereby, the second surface 10b side is stably fixed to the first surface 10a side, and the wound state is maintained.

[0039] As shown in FIG. 1, in the state of use of the cleaning tool 1, a part of the cleaning sheet 10 extends so as to protrude from the end of the roller 6 to form an extended portion 70. Also, the end 6a on the opposite side of the roller 6 is exposed to the outside.

[0040] In such a state of use, since the adhesive region 50 located on the second surface 10b side of the cleaning sheet 10 is positioned on the outer surface side of the roller 6, when the user operates the handle 4 to roll the roller 6, dust adhering to the surface to be cleaned such as a flooring floor or a carpet can be caught by the adhesive region 50.

[0041] Referring to FIG. 8(a), after use of the cleaning sheet 10, for example, in a state where the user holds the handle 4 of the cleaning tool main body 2 with the right hand, the user picks up the extended portion 70 of the cleaning sheet 10 protruding from the end of the roller 6 with the left hand and rotates it in the direction indicated by the arrow (toward the back side) as it is, so that the cleaning sheet 10 can be easily removed from the roller 6.

[0042] At this time, since the coating region 40 with a resin coating is located on the first surface 10a of the cleaning sheet 10 in contact with the roller 6, the frictional resistance generated when rotating the wound cleaning sheet 10 with respect to the roller 6 can be reduced, and the removal operation can be performed smoothly.

[0043] Also, as shown in FIG. 8(b), when the slit 15 is located in the extending portion 70 of the cleaning sheet 10 and the cleaning sheet 10 cannot be successfully rotated and removed from the roller 6, it can serve as a starting point for tearing the cleaning sheet 10 to remove it.

[0044] Again, when using the cleaning tool 1, a new cleaning unit 3 may be prepared, and the cleaning sheet 10 may be wound around the roller 6 by the attachment method described above. The cleaning tool main body 2 can be reused any number of times.

[0045] As described above, in the cleaning tool 1 according to the present invention, since a plurality of cleaning sheets are not used by pre-setting a continuous roll-shaped sheet assembly on the cleaning tool main body, dust does not adhere to the adhesive area 50 of the cleaning sheet 10 during storage of the cleaning tool 1, and it can be stored hygienically.

[0046] Also, by using the backing paper 20 of the cleaning unit 3, the user can smoothly perform the attachment operation without touching the cleaning sheet 10, so that the adhesive of the adhesive area 50 does not touch and stain the fingertips.

[0047] Also, after use of the cleaning sheet 10, the cleaning sheet 10 can be smoothly removed from the roller 6 of the cleaning tool main body 2 by a simple operation.

[0048] As described above, since the second area 32 of the cleaning sheet 10 is tapered, when its tip is bent, it acts as an easy-to-pick-up portion for picking up. Also, since the second area 32 is asymmetric with respect to the transverse center line Q, the user can visually grasp the difference between the first and second side edges 13, 14 in combination with the punch hole 25. Thereby, for example, it is possible to avoid a situation where the second side edge 14 side where the slit 15 is located is located on the proximal end side where the support portion 5 of the roller 6 is connected and cannot serve as a starting point when tearing the extending portion 70.

[0049] Figs. 9(a) and (b) show the cleaning tool 1 according to an example of the embodiment. In this embodiment, the cleaning unit 3 of the cleaning tool 1 is composed of a mount 20 and a cleaning sheet laminate 100 composed of a plurality of cleaning sheets 10 placed on the mount 20. In the cleaning sheet laminate 100, the cleaning sheets 10 are laminated in the thickness direction Z, and can be sequentially attached to the roller 6 of the cleaning tool main body 2 starting from the uppermost cleaning sheet 10S and used.

[0050] The cleaning sheets 10 constituting the cleaning sheet laminate 100 are configured such that, for example, the adhesive area 50 of the upper cleaning sheet 10S faces the coating area 40 of the lower cleaning sheet 10T. Therefore, the adhesive area 50 of the cleaning sheet 10S does not stick to the cleaning sheet 10T, and each sheet can be attached to the roller 6 of the cleaning tool main body 2 and used.

[0051] In this way, since the adhesive area 50 of the upper cleaning sheet 10S is covered by the coating area 40 of the lower cleaning sheet 10T, drying of the adhesive area 50 can be suppressed without using a separate release sheet or the like. In addition, since a plurality of cleaning sheets 10 can be set on one mount 20, the manufacturing cost can be reduced and the storage property is excellent.

[0052] Figs. 10(a) to (d) show the usage state of the cleaning sheet laminate 100. As shown in Figs. 10(a) to (c), when using the first cleaning sheet 10S, the second area 32 is folded over the first area 31, the roller 6 of the cleaning tool main body 2 is applied, and as shown in Figs. 7(a) and (b), the cleaning sheet 10S can be attached in a state of being wound around the roller 6 by rolling the roller 6.

[0053] Next, use them in the order of being sequentially laminated from the cleaning sheet 10T. As shown in Fig. 10(d), the last cleaning sheet 10U directly adhered to the mount 20 is also wound around the roller 6 in the same manner, so that all the cleaning sheets 10 constituting the cleaning sheet laminate 100 can be used.

[0054] Figures 11(a), (b) and Figures 12(a), (b) show the cleaning tool 1 according to an example of another embodiment. In this embodiment, the second edge 12 of the cleaning sheet 10 has a substantially M shape, and the cleaning sheet 10 has a pair of connecting portions 80 that are spaced apart and opposed to each other in the width direction X.

[0055] On the first surface 10a side of the cleaning sheet 10, the coating region 40 extends up to the connecting portion 80. On the other hand, on the second surface 10b side, the adhesive region 50 does not extend up to the connecting portion 80.

[0056] As shown in Fig. 12(a), when the cleaning sheet 10 is attached to the roller 6 of the cleaning tool body 2, a pair of connecting portions 80 of the cleaning sheet 10 are connected to the portion on the first edge 11 side, and a separation space S is formed between the pair of connecting portions 80. Since the pair of connecting portions 80 are connected, the wound state of the cleaning sheet 10 can be maintained.

[0057] For example, when the roller 6 of the cleaning tool body 2 is formed of a material with relatively high frictional resistance such as urethane resin, as shown in Fig. 8(a), it can be said that it is difficult to rotate the cleaning sheet 10 and remove it from the roller 6.

[0058] In this embodiment, since the cleaning sheet 10 has a separation space S in the wound state, as shown in Fig. 12(b), the user can insert a finger into the separation space S, pick up a part of the cleaning sheet 10, and easily peel it off from the roller 6 while breaking the connecting portion 80.

[0059] For the materials of the components of the cleaning tool 1 according to the present invention, various known materials commonly used in this field can be used without limitation. Also, as long as the technical effects of the present invention are achieved, the shapes and sizes of the cleaning tool body 2, the cleaning unit 3, and the first and second display marks 18, 19 can be variously changed.

[0060] The cleaning tool according to the present invention can include at least the following embodiments. The embodiments can be adopted separately or in combination with each other. (1) A first display mark is located on the first surface side of the cleaning sheet, and a second display mark is located on the second surface. In a state where the second area is bent toward the first surface side of the first area along a virtual bending curve extending in the width direction, the first display mark and the second display mark are arranged side by side in the longitudinal direction. (2) The cleaning sheet further has first and second side edges extending in the longitudinal direction. A slit extending inward in the width direction from the second side edge is formed near the second end edge of the second side edge. (3) In a state where the cleaning sheet is attached to the roller of the cleaning tool body, a part of the cleaning sheet extends from the roller to form an extending portion. (4) The slit is located in the extending portion of the cleaning sheet.
