Definitions

  • the present invention relates to a disposable diaper.
  • the present invention relates to a pants-type disposable diaper comprising a substantially rectangular front waistline member, a rear waistline member and an absorbent main body which are separate from each other.
  • a central panel of the front belt portion is joined to the front waist panel of the absorbent body, and the central panel of the back belt portion is joined to the back waist panel of the absorbent body,
  • the front belt portion and The left and right side panels of the back belt portion are joined together at or adjacent to the left and right side edges, respectively, and the waist
  • a disposable pull-on garment forming an opening and the two leg openings, wherein the longitudinal length of each side panel of the rear belt portion is longer than the longitudinal length of the corresponding side panel of the front belt portion Is disclosed.
  • FIG. 1 is a developed plan view of an embodiment of a pants-type disposable diaper according to the present invention.
  • the pants-type disposable diaper 1 includes a front waistline member 2, a rear waistline member 3, and an absorbent main body 4.
  • the front waistline member 2, the rear waistline member 3, and the absorbent main body 4 are separate from each other, and all have a substantially rectangular shape.
  • the front portion of the absorbent main body 4 overlaps with the front waistline member 2 and is joined by a hot melt adhesive or the like.
  • the rear portion of the absorbent main body 4 overlaps with the rear waistline member 3 and is joined by a hot melt adhesive or the like.
  • a thread rubber made of polyurethane elastic fiber, a rubber made of natural rubber, or an elastic sheet made of polyurethane fiber can be used. It becomes possible to repeatedly expand and contract the member in which the is disposed along the arrangement direction.
  • the shape loss is improved, and the mole performance and wearing state are improved.
  • the leakage performance is further improved. While exhibiting the same mole performance, it is possible to lower the pulp basis weight, and an absorbent core having a low pulp basis weight can reduce the cost.
  • the absorbent core does not collapse, and the absorbent core can be prevented from jumping away from the wearer's body when worn. As a result, it is possible to maintain a clean appearance even after liquid absorption.
  • the length from the crotch region side end of the compressed portion to the rear end edge of the front waistline member or the front end edge of the rear waistline member is preferably 1/10 or more of the length in the front-rear direction of the crotch region. If it is less than 1/10, the length is insufficient and sufficient collapse cannot be suppressed.
  • FIG. 7 shows an example in which the pressing parts are arranged in a diamond lattice.
  • FIG. 8 shows an example in which the pressing parts are arranged in a honeycomb lattice shape.
  • 7 and 8 show an example in which the squeezing portion is present on the entire surface of the absorbent core, but the squeezing portion is not necessarily present on the entire surface of the absorbent core, and as shown in FIGS. 9 and 10, It may be at least at the boundary between the waistline member and the crotch region.
  • the pattern of arrangement of the compressed parts is not limited to these, and any pattern such as a corrugated shape may be used as long as it straddles the boundary line between the waistline member and the crotch region.
  • the pressing part can be formed by embossing. Embossing may be performed while applying heat or may be performed without applying heat. Although the pressing part should just exist in the absorption core at least, you may emboss and process the laminated body of a leak-proof film, an absorption core, and a liquid-permeable top sheet, and may form a pressing part. Moreover, you may wrap an absorption core with a core wrap sheet
  • the disposable diaper of the present invention can be suitably used as a disposable diaper for newborns, disposable diapers for infants, disposable toilet training pants, disposable incontinence pants, disposable sanitary pants, adult disposable diapers, and the like.
