  • Patent number: 6329308
    Abstract: A disposable wipe-off article having improved durability. The disposable wipe-off article includes a heat-sealable sheet and a heat-sealable wipe-off layer including an expanded bundle of continuous filaments. The wipe-off layer is bonded to the base sheet by a plurality of heat-seal lines extending to cross the continuous filaments and intermittently arranged longitudinally of the continuous filaments.

  • Patent number: 6319593
    Abstract: A cleaning sheet including a base sheet and at least one surface layer of filaments placed on the base sheet is described. The filaments extend in one direction and each of the filaments extends over the whole length of the surface layer in the extension direction of the filaments. The base sheet and the surface layers are bonded to each other at a plurality of bonding lines intersecting the extension direction. The surface layer includes a plurality of filaments-holding regions, each of which includes at least one end of the bonding line other than the bonding lines forming the filaments-holding region. Accordingly, in the filaments-holding regions, differences-in-level for collecting dust are formed and gaps (pockets) for capturing the dust therein are exposed.

  • Patent number: 6241835
    Abstract: A cleaning product comprises a base sheet and at least one layer of filaments or split yarns oriented in one direction, the base sheet and the layer are stacked and bonded together at a plurality of bonding lines extending in a direction intersecting with the one direction, and the base sheet is cut together with the layer intermittently in the intersecting direction between adjacent bonding lines to form cutting portions, thereby forming brushing portions with the layer. The cleaning product can be produced simply and conveniently at small cost. Further, it also has an excellent dust collecting effect.

  • Patent number: 5699912
    Abstract: A container for wetted tissues comprises a container body, a stationary lid member and a movable lid member each molded from a suitable synthetic resin material. The stationary lid member fits on the container body to close an upper opening of the container body and the movable lid member is hinged to the stationary lid member so as to cover an opening formed substantially in a central zone of the stationary lid member through which the wetted tissues will be picked out. Any one of an upper surface of the stationary lid member and an inner surface of the movable lid member is provided with an elastic strip fixed across the hinged portion. As the movable lid member is closed, the elastic strip is curved generally in a U-shape or .OMEGA.-shape within a space defined between the inner surface of the movable lid member and the upper surface of the stationary lid member and thereby charged with an elastic energy biasing the movable lid member to be opened.
