ツプシートの単一層だけが存在することになり、
そのためおむつの使用上、次の如き欠点がある。 In conventional disposable diapers equipped with stretchable members that have been put into practical use, the stretchable members are located on both sides of an absorbent body between a water-permeable top sheet and a water-impermeable back sheet that cover the absorbent body. and is fixed to one or both of the sheets by adhesive. The elastic member is generally thread-like or tape-like made of rubber material or urethane foam, and as mentioned above, there is a water-permeable top sheet on both sides of the absorbent body that covers the absorbent body, and a water-impermeable top sheet that covers the absorbent body. Since the top sheet is placed between the elastic member and the wearer's skin when the diaper is worn, only the thin, porous single layer of the top sheet is present between the elastic member and the wearer's skin. ,
Therefore, the diaper has the following drawbacks when used.
(1) おむつの着用時に於ける伸縮部材の圧迫力に

者に痛みを与える。(1) Pressure marks are formed around the wearer's legs due to the compressive force of the elastic member when wearing the diaper, which causes pain to the wearer if the diaper is worn for a relatively long period of time.
(2) 伸縮部材とトツプシート側に固着するための

害を起す原因ともなる。(2) The adhesive for fixing the elastic member to the top sheet side permeates through the top sheet and oozes out to the skin of the top sheet when the adhesive is fixed. Therefore, the adhesive comes into direct contact with the wearer's skin, which not only makes the wearer feel uncomfortable, but also causes skin disorders such as rashes.

The disposable diaper is characterized in that a flexible hydrophobic net-like sheet is interposed between at least the top sheet and the elastic member.

なみに、斯かる利点は、ネツト状シート7を適
宜層数重ねることにより一層向上する。(1) The top sheet 2 at the stretchable member 6 portions becomes thicker to provide cushioning properties, and as a result, pressure marks caused by the stretchable member 6 around the wearer's legs are not formed, and even when the diaper is worn for a relatively long period of time. , does not cause pain to the wearer. Incidentally, this advantage can be further improved by stacking the net-like sheets 7 in an appropriate number of layers.

る。(2) The elastic member 6 is fixed to the inner surface of the back sheet 3 and/or top sheet 2 with an adhesive. When it is fixed to the inner surface of the top sheet 2, the elastic member 6 is applied to the upper surface of the elastic member 6 and the net valve seat 7 is fixed. It is fixed with adhesive that passes through the holes. In this case, the amount of adhesive applied to the upper surface of the elastic member 6 that passes through the mesh of the net-like sheet 7 is regulated, so that even if the applied amount is a little large, it will not pass through the top sheet 2. It does not cause skin disorders such as rash to the wearer. Incidentally, in practice, it is difficult to apply a desired constant amount of adhesive stably and evenly, and if the amount of adhesive applied is large, it may pass through the top sheet 2 and come into contact with the wearer's skin. become.
