  • the present invention relates to an individual package, in which an absorbent article, such as sanitary napkin, panty liner, sanitary tampon, incontinence pad, disposable diaper and so forth is individually packed.
  • an absorbent article such as sanitary napkin, panty liner, sanitary tampon, incontinence pad, disposable diaper and so forth is individually packed.
  • an absorbent article such as sanitary napkin or the like
  • a package sheet of the individual package is formed from a polyethylene film or the like. It is a typical structure that side portions of the package sheet are heat sealed in a condition wrapping the absorbent article.
  • the package sheet formed from a resin film such as polyethylene film and so forth may generate husky (or crinkly) noise upon handling due to friction with a packaging film upon opening the package and taking out the absorbent article. This is true even in the case where the individual package is taken out from a porch, is carried in hand, or is carried in a pocket of pants or skirt.
  • the resin films are firmly bonded by heat seal to cause difficulty in opening the package for large anti-peeling resistance upon peeling the heat sealed portion.
  • high husky or crinkly noise can be generated.
  • the package sheet formed from polyethylene film is not always preferably in terms of product form due to stiff external appearance of the individual package. Furthermore, since the polyethylene film is heat sealed, gas-tightness of the sealed individual package becomes excessively high to cause bursting of the package sheet at the heat sealed portion when large external force is applied during carrying.
  • a base end portion of a tape is fixed on a surface of the package sheet portion located at the outermost position in the condition where the end edges of the package sheet are overlapped on an outer surface of the package sheet, and a free end of the tape is extended beyond the end edge of the package sheet and is peelably bonded on the surface of the package sheet adjacent to the end edge.
  • the free end of the tape is peeled from the surface of the package sheet adjacent to the end edge, and the package sheet on which the base end of the tape is fixed is lifted up together with the tape, thereby the heat sealed portion can be peeled to easily unpack the individual package.
  • the unpacked package sheet may be used for wrapping the used sanitary napkin. Then, the free end of the tape extending from the end edge of the package sheet is bonded on the outer surface of the package sheet for disposal.
  • the base end of the tape is not firmly fixed on the package sheet, when the free end of the tape is pulled for firmly wrapping the used sanitary napkin by the package sheet, the base end may be peeled off the outer surface of the package sheet to cause difficulty in wrapping the used sanitary napkin for disposal.
  • an approach is considered to use an adhesive having high bonding strength in fixing the base end of the tape on the surface of the package sheet, and to use an adhesive having lower bonding strength in bonding the free end of the tape on the surface of the package sheet at the position adjacent to the end edge of the package sheet.
  • greater thickness may be provided for the adhesive at the portion where the base end of the tape is bonded on the surface of the package sheet, and smaller thickness may be provided for the adhesive at the portion where the free end of the tape is bonded on the surface of the package sheet.
  • the adhesive used for fixing the base end of the tape may run out toward the position of the package sheet on which the free end of the tape is bonded, to fix the free end of the tape with excessively large bonding strength on the package sheet to cause difficulty in unpacking.
  • the present invention has been worked out in view of the shortcoming in the prior art set forth above. It is therefore an object of the present invention to provide an individual package of an absorbent article which permits a base end of a tape to be bonded on a package sheet with sufficiently large bonding strength without complicating packaging process and increasing manufacturing cost.

  • the base end of the tape can be certainly and firmly secured on the surface of the package sheet.
  • the package sheet may be formed from a non-woven fabric.
  • the side edge portions of the package sheet in a plurality of layers may be bonded with each other, and the smoothed region may be located at a position away from the bonded portion of the package sheet.
  • the smoothing process may be to increase fiber density of the surface by pressurizing the surface of the package sheet. Further preferably, the smoothing process may be to increase fiber density of the surface by heating and pressurizing the surface of the package sheet.
  • the package sheet can be easily smoothed.
  • the smoothing process may be to form a resin film on an outer surface of the package sheet.
  • an individual package of an absorbent article wherein, in a condition where an absorbent article is wrapped by a package sheet having mutually opposing side edge portions and mutually opposing end edges portions, one end edge portion is overlapped over the other end edge portion with placing the one end edge portion of the package sheet outside for forming an overlapping portion, and the package sheet is releasably sealed along the side edge portions, a base end of a tape is fixed on the surface of the package sheet located outside in the overlapping portion, and a free end of the tape extends across the one end edge portion and is releasably adhered on the outer surface of the package sheet adjacent the one end edge portion, comprises:
