Description of the Related Art Conventionally, absorbent articles such as sanitary napkins and incontinence pads have been used as a liquid-permeable surface layer, a liquid-impermeable leakproof layer, and a liquid-permeable layer between the two layers. There is widely used one having a liquid-retaining absorbing layer interposed therebetween and formed substantially vertically. Such absorbent articles are required to have a high fit and prevent leakage, and various proposals have been made.

分ではなかった。For example, Japanese Patent Application Laid-Open No. 7-502438 and Japanese Patent Application Laid-Open No. 7-446 disclose an absorption member having a hollow loop separated from an absorption layer by disposing an elastic member outside in the width direction of the absorption layer. Sexual articles have been proposed. However, those having such a loop separated from the absorbent layer cannot have such a size that a sufficient fit can be obtained, and also have a stress from the left and right such as a movement of a wearer's foot. However, even in the case where a shock was applied, it was not possible to buffer at the loop portion, and stress was directly applied to the absorbing layer to cause a warp, and the leak preventing property was not sufficient.

８０80 mm. When the outer peripheral length L is less than 20 mm,
In some cases, the fitting property may be reduced, or the effect of preventing deformation may be insufficient. When the length exceeds 80 mm, the loop shape is too large, and it is difficult to fit the crotch, which is not preferable. The height of the hollow part is preferably 5 to 40 mm. If the height is less than 5 mm, the shape of the cup as the entire sanitary napkin is impaired, and the leakage prevention effect may be lost.If the height is more than 40 mm, the fit of the sanitary napkin central portion may be impaired. It is not preferable.

しくない。It is preferable that the elastic sheet has elasticity. When the elastic sheet is formed into a loop shape, the elastic sheet needs to have a rigidity such that the elastic sheet forms a loop shape and can be freely deformed without any discomfort while maintaining the loop shape. . Further, it is preferable that the material has liquid impermeability. The elastic properties of the elastic sheet are
In the longitudinal direction of the sanitary napkin, the stress at the time of elongation of 5 to 50% is preferably 50 to 500 gf / 25 mm,
100 to 300 gf / width 25 mm is more preferable. If the stress is less than 50 gf / 25 mm, the elongation is too weak, the loop does not stand up, and a favorable curve cannot be obtained in the longitudinal direction, and the fitting property becomes insufficient.
If it exceeds 00 gf / width 25 mm, the curve becomes tight in the longitudinal direction, and similarly, the fitting property is undesirably reduced.

Is more preferred. If the bulk softness value is less than 5 gf, the loop shape is too soft to keep the loop shape stable, and 200 g
When f exceeds f, it is not preferable because it is not deformed freely at the time of mounting, or it becomes uncomfortable. The bulk softness is
It can be measured as follows. That is, the elastic sheet is cut out as a strip having a size of 150 mm in the longitudinal direction and 30 mm in the width direction, and both ends in the longitudinal direction of the strip are overlapped by 5 mm to form a cylindrical shape. It is fixed at two positions by staples at a position of about 10 mm from the upper and lower edges of the cylinder. Next, it is compressed at a compression speed of 10 mm / min with a Tensilon compression tester, and the maximum compressive strength until the cylinder buckles is measured. The average value of five measurements is taken as the bulk softness value.

い。The elastic material of the elastic sheet is not particularly limited as long as it is a sheet material having the above-mentioned elastic properties and rigidity. For example, polystyrene-polyisoprene copolymer, polystyrene-polybutadiene copolymer,
Examples include films, nonwoven fabrics, woven fabrics, foams, etc. made of natural rubber, polyurethane, ethylene-α-olefin copolymers such as polyethylene-ethyl acrylate, and the like. Also,
The elastic sheet directly touches the skin on both sides of the napkin, and in consideration of the touch and the like, a nonwoven fabric material is more preferable than a film or the like. In addition, in the case of stretchable films, laminated with other thermoplastic non-woven fabrics of polystyrene / polyester, polyethylene / polypropylene, or polypropylene for the purpose of improving the feel, heat sealing property with absorbent materials and surface materials, and rigidity. You may use as. When such a nonwoven fabric is used, it is preferable that the nonwoven fabric itself also has an elastic material, and it is preferable that the nonwoven fabric itself be crimped and formed into a nonwoven fabric. A non-stretched nonwoven fabric may be superimposed on the stretched stretchable film, and these layers may be combined and adhered by hot melt or heat sealing to use as a whole stretchable sheet. The curvature radius r of the sanitary napkin, which is concavely curved toward the skin contact surface in the longitudinal direction, preferably has a radius of curvature r of 50 to 300 mm, more preferably 100 to 200 mm. If the radius of curvature r is less than 50 mm, the napkin may be too curved and the fit may be reduced or it may be difficult to attach to the shorts, and if it is more than 300 mm, it may be difficult to obtain desirable phytophysical properties for the body.

Since it can be held in a state that it is always fitted to the body and can absorb menstrual blood without forming a gap, it is particularly excellent in preventing lateral leakage. Specifically, since the hollow portion 5 is formed of an elastic sheet, even when the wearer moves during use, the hollow portion is freely deformed to prevent a gap from being generated in the mounting portion, and the body portion is formed on the body. Fit. Also, even when the wearer receives a stress from the width direction of the absorbent article such as walking, the hollow part receives the stress and is relaxed, so that the stress received by the absorber can be small, and it is difficult to bend. It has a high fit and is less likely to leak. This effect is particularly remarkable when the elastic sheet is directly joined to the absorber.
