いる。(Prior art) Normally, the basic structure of paper diapers is as shown in the cross section in Figure 3, in which paper cotton, super absorbent resin, etc. are laminated on a water-impermeable sheet 1 such as a vinyl sheet. The formed water-absorbing layer 2 is placed, its surface is covered with a water-permeable sheet 3 such as a non-woven fabric, and the water-permeable sheet 3 and the water-impermeable sheet 1 are joined at four circumferences.

具を汚すことが多い。 In the case of the paper diaper with the above structure, the water seeping out from the end of the water absorbing layer 2 at the boundary with the skin, that is, the part placed on the back and abdomen, and the part placed along the base of the feet, passes through the surface. It often leaks into the aqueous sheet 3 and adheres directly to the skin or stains clothes and bedding.

のがある。図において６は接合部である。 Conventionally, in order to prevent the above-mentioned leakage, a waterproof sheet 4 such as a vinyl film having a required width is attached to the end 2a of the water absorption layer 2 and a water permeable sheet, as shown in the enlarged cross-sectional view of FIG. 3 and one side thereof is sandwiched and fixed between the end joints of the water-impermeable sheet 1 and the water-permeable sheet 3, so that moisture seeping out from the end 2a of the water-absorbing layer 2 is prevented from passing through the surface. The water-permeable sheet 3 is coated with resin on the inner surface of the end portion to form a waterproof portion 5, and the end portion 2a of the water-absorbing layer 2 is Some are designed to prevent exuding water from reaching the outer surface of the water-permeable sheet 3. In the figure, 6 is a joint.

てコストが高くなるという問題がある。 In addition, according to the above structure, it is necessary to sandwich and join the waterproof sheet 4 between the ends of the water-impermeable sheet 1 and the water-permeable sheet 3, which necessitates a step of sandwiching the waterproof sheet 4. There is a problem that as the number increases, it impedes the speeding up of manufacturing machines and increases costs.
また、第５図に示す通水性シート３の内面に樹

手段では適格な効果を期待することは難しい。 Furthermore, the method in which the waterproof portion 5 is formed by coating the inner surface of the water-permeable sheet 3 with resin as shown in FIG. 5 has the following drawbacks. In other words, non-woven fabric is generally used as the water-permeable sheet 3, but this non-woven fabric is brushed on the inner surface (water-absorbing layer 2 side) in order to reduce the backflow of moisture from the inner surface to the outer surface. It is difficult to coat the surface with resin, and even if it were possible to coat it, the leak-proofing effect would be extremely poor. As a result, it is necessary to select and use a nonwoven fabric whose inner surface is not brushed, but although it is possible to prevent leakage at the edges of the paper diaper, it is necessary to use a nonwoven fabric that does not have a raised inner surface. Therefore, it is difficult to expect an adequate effect by applying a resin coating to the inner surface of the nonwoven fabric to prevent leakage from the edges of the paper diaper.

内面に樹脂のコーテイング層を形成すると、前記
第４図示の防水シート４を介挿した場合と同様に

ざわりが悪くなるという欠点がある。 Furthermore, if a resin coating layer is formed on the inner surface of the water-permeable sheet 3 constituting the skin-side surface, the waist and crotch areas will become stiff when worn, similar to when the waterproof sheet 4 shown in FIG. 4 is inserted. The disadvantage is that the texture becomes worse when worn.

しない。(Function) As described above, a thin paper is interposed between the water-absorbing layer and the water-permeable sheet, and a water-impermeable surface is formed on the surface of the thin paper corresponding to the region from the part overlapping the edge of the water-absorbing layer to the joint edge. By forming this, the water seeping out from the end of the water absorption layer is prevented from leaking to the water permeable sheet side by the water impermeable surface, and does not leak to the waist area (or crotch area). .
In addition, since the water-impermeable surface is formed by applying a water-repellent and leak-proof liquid to the thin paper, the product does not feel stiff when worn, and has a particularly pleasant texture. Furthermore, the thin paper can be made into the same size as the water-impermeable sheet and the water-permeable sheet and can be layered on top of the water-absorbing layer to form a paper diaper.
There is no need for a separate process such as inserting a tarpaulin sheet.

洩が防がれる。 Since the present invention is constructed as described above, when urine is urinated, it permeates through the water-permeable sheet 3 and the thin paper 7 on the surface and is absorbed into the water-absorbing layer 2. When the water absorbed in the water supply layer 2 reaches the end of the water supply layer 2, it oozes out between the water impermeable sheet 1 and the thin paper 7, but a water impermeable surface 8 is formed on the thin paper 7 in this part. Since the end portion 2a of the water-absorbing layer 2 is covered with this water-impermeable surface 8, the water seeping from the end of the water-absorbing layer 2 is prevented from leaking to the water-permeable sheet 3 side on the surface. This prevents leakage to the waist area.

As explained above, the paper diaper according to the present invention is
Between the water-absorbing layer and the water-permeable sheet that contacts the skin side, at least one surface corresponding to the area from the area overlapping the edge of the water-absorbing layer to the joint edge has water-repellent and leak-proof properties such as silicone oil. By interposing a thin paper coated with a liquid to form a water-impermeable surface, the water seeping out from the edge of the water-absorbing layer is prevented from leaking to the water-permeable sheet side by the water-impermeable surface of the thin paper. Since the water-permeable sheet does not get wet, moisture does not reach the skin, so there is no discomfort, and clothes and bedding are prevented from getting soiled.
そして排尿時には通水性シートを通つて滲込ん
