发明名称 Cleaning tool and cleaning sheet
摘要 In a wet sheet, hydrophobic outer layer sheets are disposed on both sides of the hydrophilic inner layer sheet impregnated with cleaning solution. Each of intermediate layer sheets is folded over so as to form a space having an opening. End portions of the inner layer sheet are inserted into the spaces of the intermediate layer sheets. The inner layer sheet can come in contact with the outer layer sheet via a space between the intermediate layer sheets. With such a construction, sufficiently high frictional force acts between the inner layer sheet and the outer layer sheet.

主权项 1. A cleaning tool, including a cleaning sheet mounting member and a cleaning sheet, in which the cleaning sheet mounting member has a cleaning side and a holding member and the cleaning sheet has a central portion which is placed on the cleaning side of the cleaning sheet mounting member and an end portion which is formed on at least one side of the central portion in one direction and removably held by the holding member, wherein: the central portion of the cleaning sheet has a hydrophobic first sheet, a hydrophobic second sheet, a hydrophilic third sheet and a hydrophobic fourth sheet, the third sheet is impregnated with cleaning solution and disposed between the first sheet and the second sheet, at least part of the fourth sheet is disposed between the first sheet and the third sheet such that part of the third sheet can come in contact with the first sheet, and at least one end portion has a first part having a first elongation rate and a second part having a higher elongation rate than the first part, and the second part is disposed on the central portion side of the first part in one direction, and at least part of a boundary between the first and second parts is removably held by a holding member.
