Embodiment Construction

[0044] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0045] [Basic structure of sanitary napkin 1]

[0046] The sanitary napkin 1 of the present invention is as follows Figure 1 to Figure 3 As shown, there is a liquid-impermeable back sheet 2 made of a polyethylene sheet or the like, and a liquid-permeable front sheet 3 that allows menstrual blood, leucorrhea, etc. (hereinafter also collectively referred to as bodily fluids) to quickly permeate. The absorber 4 made of cotton pulp, synthetic pulp, etc. sandwiched between the materials 2 and 3, the side sheets 7 and 7 provided over substantially the entire length in the longitudinal direction on both sides of the skin-contacting surface side, and Around the absorber 4, the outer edges of the back sheet 2 and the front sheet 3 are joined by adhesives such as hot melt glue or bonding means such as heat sealing and ultrasonic sealing at the front and r...

Abstract

The purpose of the present invention is to reduce discomfort during wearing and prevent leakage from the side part. The absorbent article is provided with an absorbent body (4) and side sheets (7) disposed over the entire length in the longitudinal direction on both longitudinal side portions on the skin contact surface side. The side sheet (7) is not provided with an elastically stretchable member. In a longitudinal section including a region corresponding to a bodily fluid discharge section (H) of a wearer, a non-adhesive section (10) in which a widthwise central section of the side sheet (7) is not adhered to the absorbent body (4) side is formed, and adhesive sections (11, 12) in which the side sheet (7) is adhered to the absorbent body (4) side are formed on the widthwise outer side and both lengthwise end sides of the non-adhesive section (10), respectively. The end edge of the side sheet (7) on the center side in the width direction is positioned closer to the center side in the width direction than the side edge of the narrowest section (4a) of the absorbent body (4) in a longitudinal section including a region corresponding to the bodily fluid discharge section (H) of the wearer. The end edge of the adhesive section (11), which is adjacent to the outside in the width direction of the non-adhesive section (10), on the center side in the width direction is provided at a position overlapping the side edge of the narrowest section (4a) of the absorbent body (4) or in the vicinity of the position.

Description

technical field [0001] The present invention mainly relates to absorbent articles such as sanitary napkins, leucorrhea sheets, incontinence pads, and toiletries, and more specifically, to an absorbent article that avoids arranging elastic elastic members in side panels in order to reduce the uncomfortable feeling during wearing. Background technique [0002] Conventionally, as the absorbent article, a liquid-impermeable back sheet such as a polyethylene sheet or a polyethylene sheet laminated with a non-woven fabric, and a liquid-permeable front sheet such as a non-woven fabric or a perforated plastic sheet are known. A structure in which an absorber made of cotton pulp or the like is sandwiched between sheets. [0003] In particular, in sanitary napkins for night use, in order to prevent side leakage such as menstrual blood and other body fluids flowing in the width direction and leaking from the side edges during wearing, it has been proposed to form a large number of them...
