Problems solved by technology

[0004] However, since the thickness is thin, the absorption capacity per unit area is small, and the liquid retention capacity in the thickness direction is low, so it has the property that the body fluid easily spreads in the plane direction
Therefore, in particular, there is a disadvantage that the possibility of causing leakage (lateral leakage) from the widthwise edge of the absorber is high.
In addition, since the wearer feels uneasy about leakage, life inconvenience such as having to frequently replace the absorbent article occurs.

Embodiment Construction

[0030] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[0031] [Basic structure of sanitary napkins]

[0032] Such as figure 1 and figure 2 As shown, the sanitary napkin 1 of the present invention has: a liquid-impermeable back sheet 2, which is made of a polyethylene sheet or the like; a liquid-permeable front sheet 3, which prevents menstrual blood or secretions, etc. body fluid.) quickly penetrate; the absorber 4, which is sandwiched between the above-mentioned back sheet 2 and the front sheet 3, is made of cotton-like pulp or synthetic pulp; and the side non-woven fabrics 7, 7, which are It is provided on both sides of the skin-contacting surface within approximately the entire length. And around the absorber 4, at the upper and lower edge portions, the outer edge portions of the back sheet 2 and the front sheet 3 are joined by adhesives such as hot-melt adhesives or by joining methods such as heat sealing ...

Abstract

In the present invention, an absorbent body has, on at least the top surface sheet side thereof, a core press which is recessed toward a back sheet side and in which the absorbent body is compressed in the thickness direction. A pair of left and right compressed grooves is formed on at least both sides of a region corresponding to a body fluid discharge part of a wearer in the longitudinal direction of a sanitary napkin. A high absorbent part having higher absorption capacity per unit area than the other part is formed at least between the left and right compressed grooves of the absorbent body.

Description

technical field [0001] The present invention relates to absorbent articles mainly used for sanitary napkins, panty liners, incontinence pads, toilet products and the like. Background technique [0002] Conventionally, as the absorbent article, a polyethylene sheet or polyethylene sheet laminated with a liquid-impermeable back sheet such as a non-woven fabric and a liquid-permeable front sheet such as a non-woven fabric or a liquid-permeable plastic sheet is known. An absorbent article in which an absorber made of cotton pulp or the like is interposed therebetween. [0003] Slender absorbent articles with a thinner thickness of the absorbent body have the advantages of reducing discomfort when worn, and making it difficult to see the unevenness of the absorbent article from the outside of the clothes when worn (no influence on the external image), etc. Therefore, it is widely offered to the market. [0004] However, since the thickness is thin, the absorbing capacity per un...
