  • 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.

  • Publication number: 20130240556
    Abstract: Provided is a compact wet wipes package, wherein wet wipes can be easily drawn from a storage container, and the production cost can be kept low. This wet wipes package is provided with: a wet wipes folded body which is continuously folded and stacked, and in which dividing portions are formed at a predetermined interval; an airtight storage container which is formed to store the wet wipes folded body and includes an opening portion from which stored wet wipes are to be drawn outward; a base plate which is attached to the opening portion and is formed with a pinching hole through which the wet wipes are pinched and drawn outward; a drawing hole which is linked with the pinching hole and functions to divide the wet wipes at the dividing portion; and openable/closable lid which can hermetically close the pinching hole and the drawing hole.

  • Patent number: 8146197
    Abstract: A cleaning device superior in dust collecting capacity allows material selection from a wide range of fibers and a base material sheet forming the same and can be produced in a short processing time while preventing thermal deterioration and hardening of the material. A process for producing it is also disclosed. A cleaning device 1 is obtained by providing a large number of filaments 30 aligned in fiber direction with a linear bundling portion 40 connecting the fibers to each other by heat-sealing, forming a filament bundling body 31 previously bundled by the bundling portion 40, and bonding the filament bundling body 31 to a base material sheet 6 by an adhesive. A bristle-like-member-less portion 14 of a brush sheet 9 with a plurality of bristle-like members 8 is integrally bonded to a fiber bundle 7 and the base material sheet 6 by an adhesive.

  • Patent number: 7870635
    Abstract: The present invention relates to a cleaning tool sheet and a cleaning tool capable of use for wiping cleaning by contacting the surface of objects to be cleaned in various locations. In a cleaning tool sheet (1), fiber bundles (3) are laminated on one side face of a base sheet (2); the central parts in the direction of flow of the fibers constituting the fiber bundles (3) are joined by a central joining part (4) continuously formed in the central part of the base sheet (2) and joined at a spot-form joining part (7) formed intermittently on a parallel line between the central joining part (4) and two end edges (2a, 2b) parallel therewith. The two ends (31a, 31b) in the direction of flow of the fibers of the fiber bundles (3) are not joined to the base sheet (2). An attaching part (8) for attaching onto a holding member is provided at both ends of the base sheet (2).

  • Patent number: 7571510
    Abstract: A cleaner capable of more effectively collecting dirt or dust on a complex-shaped surface or in fine portions including corner sections. The cleaner has a cleaner body (2) and a fringe band (13). The cleaner body (2) is formed by superposing and fusion-bonding tongue-like sheet bodies (7, 8) together. The sheet bodies (7, 8) have peripheral edge sections forming a curvilinear outline, and the fusion-bonding is made at this peripheral edge sections. The fringe belt (13) is fusion-bonded to a surface section of the sheet body (7) of the cleaner body (2). An insertion section (20) from which a hand as a supporting body can be inserted is formed in the cleaner body (2), and a space section (21) is formed toward the bottom of the gap between the superposed sheet bodies (7,8). The fringe belt (13) is convexly curved in the direction from the insertion section (20) to the bottom of the space section (21).
