Definitions

  • the present invention relates to sanitary thin paper.
  • Some sanitary thin paper such as kitchen paper has a laminated structure in which sheets of crepe paper or the like subjected to embossing are laminated.
  • each sheet is embossed to provide oil and moisture absorption performance, and a convex portion is formed on one surface, and a concave portion corresponding to the convex portion is formed on the other surface.
  • a space embssed space
  • each sheet in order to improve design and absorption performance (moisture and oil absorption, retention, absorption speed, etc.), each sheet has no embossed irregularities (non-embossed) facing each other. A non-embossed space is formed, and an oil component or the like is allowed to pass through the non-embossed space so that the absorption performance of the oil component or the like is enhanced.
  • FIG. 2 of Japanese Patent Publication No. 6-28951 shows a tip-to-tip format in which the tops of the convex portions of two embossed crepe papers are bonded to each other.
  • Sanitary paper such as kitchen towels having the laminated structure is disclosed (see FIGS. 10 to 13).
  • Patent Document 3 discloses a kitchen paper provided with a line-shaped non-embossed space intersecting the inside (see FIGS. 10 to 17).
  • Patent Document 1 tip-to-tip type laminated structure
  • the strength in the lamination direction tends to be low
  • sanitary thin paper for example, fried food on kitchen paper laid on a plate
  • the oil absorbed by the load oozes out (back through) on the back side of the sanitary thin paper (for example, a dish on which kitchen paper is placed) (see FIGS. 10 to 13).
  • Patent Document 2 laminated structure
  • the structure of Patent Document 2 can reduce the contact area with the object to be used, but the embossed space in the sanitary thin paper is small compared to the tip-to-tip laminated structure. Therefore, even when the embossed space is slightly crushed when a load is applied during use, the oil content or the like is difficult to be absorbed, and the absorbed oil content oozes out (see FIGS. 14 to 17).
  • the strength in the thickness direction can be increased by reducing such non-embossed space
  • the diffusibility of oil or the like is reduced because the space volume of the non-embossed space is reduced.
  • the area of the non-embossed part in each sheet is reduced, the design is lowered. Further, when there is an intersection where the non-embossed space intersects in the space sandwiched between the sheets, oil or the like stays in the intersection and the oil or the like is prevented from diffusing, so that the oil absorption performance further decreases.
  • An object of the present invention is to provide a sanitary thin paper excellent in absorption performance under load while maintaining diffusibility and design.
