  • Publication number: 20140190859
    Abstract: A wet tissue package having a folded wet tissue body that has a separation section formed so that the wet tissues can separate. A housing container houses the folded wet tissue body and has an opening formed for the wet tissues configuring the housed folded wet tissue body to be pulled out therefrom. The wet tissue package also has a base plate attached to the opening and to which a notch section has been formed at a predetermined position. The notch section has a plucking hole and a portion of the opening's edge of the base plate that is attached to the opening. The notch section is provided with a removal hole that interconnects with the plucking hole and separates a wet tissue from the wet tissue body at the separation section. The wet tissue package also has a lid that can seal the plucking hole and removal hole.

  • Patent number: 8557360
    Abstract: An inexpensive cleaning sheet is provided which attains an excellent cleaning efficiency and with which even large dust particles or heavy dust particles can be easily caught. The cleaning sheet is obtained by bonding a cleaning-side sheet to a base sheet at bonding areas, interposing a strip between the base sheet and the cleaning-side sheet, bonding the strip to the cleaning-side sheet, with one end of the strip projecting outward from the cleaning-side sheet, forming a perforation for cutting off in the cleaning-side sheet, and forming a pressure-sensitive adhesive layer on the surface of the base sheet which faces the region of the cleaning-side sheet surrounded by the perforation. This cleaning-side sheet is configured so that the region of the cleaning-side sheet surrounded by the perforation is cut off by pulling the strip.
