Amendment January 23, 1983 The name of the invention is amended as follows. Name of the invention: Sanitary napkin The scope of the utility model registration claims and the brief description of the drawings are amended as follows.

[Claims for Utility Model Registration] (1) In a napkin formed by covering an absorbent body with a water-impermeable sheet and a water-permeable sheet, a substantially rectangular absorbent body 2 is located in the center of a substantially rectangular non-water permeable sheet 1. A thin absorbent body 8 is placed in the outer side portions on both sides, which is further covered with a water-permeable sheet 10, and the periphery of the long side is fused and fixed, and the inner portion from the center of both side portions 7 is folded. Fold each side toward the water-permeable sheet side, and then fold back from the base of both side portions 7 toward the non-water-permeable sheet side to form pleats 12, and fuse and fix both longitudinal edges 14 in the overlapping state, Furthermore, the sanitary napkin is made by pasting adhesive tape 15 on the surface of the pleats . (2) The sanitary napkin according to claim 1, wherein the water-impermeable sheet is waterproof paper or/and polymer film . (3) The sanitary napkin according to claim 1 or 2, wherein the water-permeable sheet is a nonwoven fabric fixed with binder fibers . (4) The absorbent body is formed of a pulverized cellulose fiber selected from pulp, linter, and regenerated cellulose, or a superabsorbent material containing a liquid absorbent and/or liquid coagulant in the pulverized cellulose fiber. A sanitary napkin according to any one of claims 1 to 3 of the utility model registration claims, which is a superabsorbent sheet . (5) A sanitary napkin according to any one of claims 1 to 4 of the utility model registration claim, wherein the thin absorbent material is a superabsorbent sheet .

Claims (1)

[Scope of Claim for Utility Model Registration] (1) A substantially rectangular absorbent body is arranged in the center of a substantially rectangular non-water permeable sheet such as laminated paper or polyfilm, and the sides of both sides are folded as appropriate toward the ends. Similarly, approximately rectangular absorbent paper or polymer sheets are arranged, and these are covered with a water permeable sheet such as a non-woven fabric having the same shape as the non-water permeable sheet, and the periphery of each long side is fused to form an absorbent body. Then, fix the absorbent paper or polymer sheet, etc., and fold the appropriate inner parts from the center of both side parts toward the water-permeable sheet side, and then fold back from the bases of both side parts toward the non-water-permeable sheet side to form pleats. A sanitary napkin formed by fusing both longitudinal edges of the polymerized product. (2) The sanitary napkin according to claim 1, wherein the ends of both side parts when folded back toward the water-impermeable sheet side protrude appropriately from the long sides of the absorbent body. . (3) The absorbent body covered with the water-impermeable sheet and the water-permeable sheet is mainly made of a superabsorbent sheet or pulverized (cotton-like) pulp, and the absorbent body is covered with the water-permeable sheet by the water-impermeable sheet. A sanitary napkin according to claim 1, wherein the sanitary napkin is coated with the abutting surface left open to an appropriate width. (4) The utility model according to claims 1 and 3, characterized in that both long sides of the absorbent body are each cut inward into a substantially circular arc shape or a substantially trapezoidal shape. sanitary napkins. (5) Practical use characterized in that both side parts where the pleat parts are formed are stretched outward and laterally and turned over to the water-permeable sheet side, so that the both side parts wrap around the absorbent body. A sanitary napkin according to claim 1 of the patent registration claim.
