Abstract

To provide a cleaning tool exhibiting excellent usability. The present invention relates to a cleaning tool comprising a cleaning sheet, and a holding tool for holding said cleaning sheet. The cleaning sheet is provided with: a brush part capable of cleaning an object to be cleaned; a base part; and insertion parts for the holding tool. The brush part is formed from: a first brush part provided to one side of the base part; and a second brush part provided to another side of the base part. The first brush part and the second brush part are provided with a first region and a second region which each have different configurations.

First claim

The invention claimed is:

1. A cleaning tool, comprising:
a cleaning sheet; and
a holder configured to hold the cleaning sheet,
wherein
the cleaning sheet has
a longitudinal direction which is defined by a direction of insertion of the holder into the cleaning sheet, and
a transverse direction crossing the longitudinal direction,

the holder has
a holding part configured to hold the cleaning sheet, and
a grip part connected to the holding part and configured to be held by a user,

the cleaning sheet has
a brush part configured to clean an object to be cleaned,
a base, and
an insertion part which is formed on the base and into which the holding part is to be inserted,

the brush part includes a first brush part provided on one side of the base and a second brush part provided on the other side of the base,
the first brush part has first and second brush regions alternatingly arranged in the longitudinal direction,
a width of the second brush region in the transverse direction is greater than a width of the first brush region in the transverse direction,
the brush part and the base are joined together at a central bonded part in the first and second brush regions,
the brush part and the base are further joined together at a lateral bonded part at the second brush region,
the first brush region has a first contact region on a side of the central bonded part,
the second brush region has a second contact region between the central bonded part and the lateral bonded part, and
a thickness of the first brush part at the second contact region in a thickness direction of the cleaning tool is less than a thickness of the first brush part at the first contact region in the thickness direction, the thickness direction being perpendicular to the longitudinal direction and the transverse direction.

2. The cleaning tool as defined in claim 1 , wherein
the brush part comprises first fiber assembly which forms the first brush part and a second fiber assembly which forms the second brush part, and
the first fiber assembly and the second fiber assembly have different finenesses.

3. The cleaning tool as defined in claim 1 , wherein
the first brush part comprises a fiber assembly, and
the second brush part comprises a nonwoven fabric.

4. The cleaning tool as defined in claim 1 , wherein
the first brush part comprises a fiber material, and
the second brush part comprises a foam.

5. The cleaning tool as defined in claim 1 , wherein
the first brush part comprises a fiber material containing a dust adsorbing oil, and
the second brush part comprises a fiber material containing no dust adsorbing oil.

6. The cleaning tool as defined in claim 1 , wherein
the first brush part comprises a hydrophilic fiber material, and
the second brush part comprises a non-hydrophilic fiber material.

7. The cleaning tool as defined in claim 1 , wherein
the first brush part contains water, and
the second brush part does not contain water.

8. The cleaning tool as defined in claim 1 , wherein
the first brush part has a first colored region, and the second brush part has a second colored region having a color different from the first colored region, and
a coloration pattern is formed by the first and second colored regions.

9. The cleaning tool as defined in claim 1 , wherein
the first brush part has a first fragrance region and the second brush part has a second fragrance region, and
the first fragrance region and the second fragrance region have different fragrance substances.

10. The cleaning tool as defined in claim 1 , wherein the base comprises a first sheet element.

11. The cleaning tool as defined in claim 10 , wherein
the base further comprises a second sheet element superposed on the first sheet element, and
the insertion part is formed between the first sheet element and the second sheet element.

12. The cleaning tool as defined in claim 10 , wherein
the first sheet element has surfaces contacting and bonded with each other to form the insertion part.

13. The cleaning tool as defined in claim 10 , wherein
the base further comprises a pair of further sheet elements superposed on the first sheet element, and
the insertion part is formed between the pair of further sheet elements.

14. The cleaning tool as defined in claim 10 , wherein
the base further comprises a further sheet element superposed on the first sheet element, and
the further sheet element has surfaces contacting and bonded with each other to form the insertion part.

15. The cleaning tool as defined in claim 1 , wherein
the second brush region further has a third contact region adjacent to the second contact region in the transverse direction and adapted to contact with the object to be cleaned.

16. The cleaning tool as defined in claim 15 , wherein
a highest point of each of the second and third contact regions in the thickness direction is lower than a highest point of the first contact region in the thickness direction.

17. The cleaning tool as defined in claim 1 , wherein the thickness of the first brush part at the first contact region gradually increases from the center bonded part to lateral ends of the first brush part.
