Embodiment Construction
[0049] Figure 1 to Figure 6 One embodiment of the absorbent article of the present invention is shown, and in this embodiment, a case where the absorbent article is a sanitary napkin will be described.
[0050] Specifically, this sanitary napkin 1 has a lengthwise direction (L), a widthwise direction (W), and a thickness direction (D), and has a top sheet 2 as a liquid-permeable layer, and is arranged on one side of the top sheet 2. The backsheet 3 as a liquid-impermeable layer, and the absorbent body 4 disposed between the topsheet 2 and the backsheet 3.
[0051] In addition, the backsheet 3 is provided with an adhesive sheet 5 for attaching the sanitary napkin 1 to the crotch of the panties.
[0052] The bottom sheet 3 is located on the underwear side of the user of the sanitary napkin 1 ( figure 2 The lower surface side of the absorbent body 4) is used to prevent the discharged excrement from penetrating to prevent leakage into underwear and the like.
[0053] The back...

Abstract
The present invention provides an absorbent article capable of maintaining a good skin feel of a top sheet, suppressing peeling of the top sheet and an absorber as much as possible, and stably maintaining absorption performance. In the absorbent article, the top sheet (2) includes a plurality of protrusions (11) extending along the length direction and formed at predetermined intervals in the width direction, and extending along the length direction and formed on these protrusions (11). A plurality of grooves between parts (11). The groove (12) includes a first recess (21) having a first bottom (22), and a plurality of second recesses (26) formed in the first recess (21). The second concave portion (26) has a second bottom portion (28) having the highest fiber density in the top sheet (2). The portion of the second surface (2b) at the top (13) of the convex portion 11 is not joined to the absorber (4). The second bottom (28) of the second recess (26) of the groove (12) is joined to the absorber (4).
Description
technical field [0001] The present invention relates to absorbent articles such as sanitary napkins, disposable diapers, and incontinence pads. Background technique [0002] Absorbent articles, such as sanitary napkins for absorbing excretions such as menstrual blood, generally include a liquid-permeable top sheet on the wearer's skin side, a liquid-impermeable back sheet on the clothing side, And an absorbent body disposed between the top sheet and the back sheet. [0003] Since the topsheet of an absorbent article is the part that comes into contact with the user's skin, it is important that it is soft and feels good on the skin. [0004] Therefore, in recent years, use is provided with the top sheet of the groove portion of the space between the protruding part of multirow ridge shape and the space between adjacent convex parts on the surface contacting with skin mostly, for such top sheet, Since the relatively soft protrusions are in contact with the skin and the protr...
