Abstract
To provide a cleaning tool exhibiting excellent cleaning effectiveness. 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 configured from a fiber, and is provided with first brush regions and second brush regions. The second brush regions are provided with protruded regions configured so as to be longer than the first brush regions.
Claims14
A cleaning tool, having comprising:
- a cleaning sheet;
- and
- a holder configured to hold the cleaning sheet,
- wherein
- the cleaning sheet extends in a longitudinal direction which is defined by a direction of insertion of the holder into an insertion part of the cleaning sheet, and in 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 first sheet element,
- a brush part provided on one side of the first sheet element and configured to clean an object to be cleaned, and
- the insertion part into which the holding part is configured to be inserted,
- the cleaning sheet has a central position in the transverse direction,
- the brush part and the first sheet element are connected by a central bonded part extending in the longitudinal direction through the central position of the cleaning sheet,
- a part of the brush part and the first sheet body are connected by lateral bonded parts on two sides of the central position in the transverse direction,
- the brush part comprises a fiber assembly of fibers having the same length and oriented in the transverse direction,
- the fiber assembly of fibers includes
- a first brush region, and
- a second brush region which is longer than the first brush region and has a protruding region,
- the first brush region includes first fibers connected to the first sheet element by the central bonded part and not connected to the first sheet element by the lateral bonded parts,
- the second brush region includes second fibers connected to the first sheet element by the central bonded part and the lateral bonded parts,
- the brush part has a contact region configured to contact the object to be cleaned,
- the contact region has
- a first contact region in the first brush region,
- a second contact region in the second brush region and between the central bonded part and one of the lateral bonded parts, and
- a third contact region in the second brush region and between the one of the lateral bonded parts and an open end of the brush part,
- the brush part has a higher modulus of elasticity in tension than the first sheet element, and
- the brush part is connected to the first sheet element by the central bonded part and the lateral bonded parts in a tensioned state.
