Definitions

  • the present invention relates to an absorbent article provided with a tape for post-treatment.
  • Absorbent articles such as sanitary napkins, panty liners, adult incontinence pads or fecal pads are attached to the inside of the worn articles worn by the wearer when in use.
  • an absorbent article attached to the inside of a wearing article has an adhesive portion for preventing displacement of the absorbent article relative to the wearing article. This adhesive part is provided in the surface on the opposite side to the skin surface side (side facing the wearer's skin) of the absorbent article.
  • Patent Document 1 discloses an absorbent article such as a disposable diaper or a sanitary napkin provided with a fastening tape for post-treatment.
  • the fastening tape comprises a base fixed to the back sheet and an extendable extension connected to the base.

  • the adhesive portion of the extension can be adhered to the back sheet of the absorbent article upon disposal by means of a strong adhesive surface.
  • the inventors of the present invention have found out the following problems with the tape member for post-processing as a result of intensive studies. That is, conventionally, it was not assumed that the tape member for post-processing gives the wearer an uncomfortable feeling of wearing. However, it has been found that, during wearing of the absorbent article, curling of the end of the sheet near the post-treatment tape member may cause part of the tape member to be in direct contact with the wearer's skin.
  • the absorbent article is pushed toward the wearer's skin by the clothes. Therefore, the tape member may cause an uncomfortable feeling.
  • the absorbent article in a state of being rounded in accordance with the roundness of the buttocks.
  • the tape member having a relatively high rigidity is disposed in such a curved region, the wearer may be more uncomfortable. Therefore, the absorbent article provided with the tape member which can control discomfort is desired.
  • the absorbent article includes a front and back direction, a width direction orthogonal to the front and back direction, a top sheet facing the wearer's skin, a back sheet directed to the side opposite to the wearer's skin, and And a post-processing tape member fixed to the main body, the main body including the front sheet and the absorber between the back sheet, and the bending rigidity of the tape member being the front sheet It is lower than the bending rigidity of the portion where the back sheet and the absorber overlap.
  • FIG. 1 is a plan view of the absorbent article according to the first embodiment viewed from the skin surface side.
  • FIG. 2 is a plan view of the absorbent article according to the first embodiment as viewed from the non-skin surface side.
