３１を融着する製造法を特徴としたものである。To explain the details with a diagram, an absorbent layer (α) made of absorbent paper such as a sheet polymer is made into a flat shape, waterproof paper (b) is layered on one side, and the whole is covered with an absorbent material (c) such as non-woven fabric. Divide the flat absorbent surface into thirds in the horizontal direction and make both end pieces (2)
(2) is folded inward from the crease (25 (2)), and the free end pieces (2α) (2a) are further folded outward and polymerized,
Both edges (3) in the longitudinal direction including the folded overlapping part (
31 is characterized by a manufacturing method in which 31 is fused.

り洩れる原因となっている。In addition, a double-sided adhesive piece + 4) (4) is attached to the bottom of the folded end piece (2α) (2a), so that the center of the conventional flat napkin is not fixed, and the whole becomes wrinkled, reducing the absorption area. This causes leakage.

It can be used as a napkin corresponding to each size for night use, allowing for a wide range of uses. As an absorbent, the folded parts on both sides and the central part that corresponds to the private parts have different thicknesses, so only the center is prone to wrinkles due to the difference (the center is naturally formed into a convex shape with a medium height, and the thickness of the central part that corresponds to the private parts is different). Furthermore, the bent end pieces (2) (2), which are bent over the free end pieces (2α) (2α), form a saucer to completely prevent leakage. Since it is formed using absorbent paper that is twice the size, the absorbent area is also twice that of the conventional one.

以上の如く本願によれば製造方法が極めて簡単で、しか

あるものである。As described above, according to the present application, the manufacturing method is extremely simple, and the part that touches the local area is naturally formed with a medium height, the two wings completely prevent leakage, and the absorption area is extremely thick, twice that of the conventional one.
It also has the effect of being able to accommodate various sizes depending on the degree of expansion.
