Abstract:
A cleaning tool that includes a cleaning element. The cleaning element includes two insert holes which receive two holding elements and extend in a first direction, a first sheet and a second sheet which are formed of nonwoven fabric, a first inner bonding part and a first outer bonding part by which the first and second sheets overlaid one on the other are bonded together and which define the first insert hole, a second inner bonding part and a second outer bonding part by which the first and second sheets overlaid one on the other are bonded together and which define the second insert hole, an intermediate region which is formed between the first inner bonding part and the second inner bonding part, and a fiber element formed by a plurality of fibers which extend in a second direction transverse to the first direction and are bonded to the first sheet in the intermediate region. When the two holding elements are inserted into the associated insert holes, the two insert holes are moved toward each other, so that the fiber element in the intermediate region is pushed out in a direction in which the fiber element is located with respect to the two insert holes.
