Definitions

  • the present invention relates to absorbent articles, more preferably disposable personal care articles such as diapers, baby pants, adult incontinent garments, feminine hygiene garments and the like. More specifically the present invention relates to an illuminative absorbent article comprising a back sheet having at least one illuminative region wherein a plurality of illuminative elements is provided.
  • absorbent articles can play an important role in improving a general safety of a wearer such as a baby or patient.
  • an absorbent article comprising a liquid pervious top sheet, a liquid impervious back sheet, and an absorbent core comprising absorbent material, said absorbent core being positioned in between said top sheet and said back sheet, wherein the back sheet comprises, at a garment facing surface thereof, at least one illuminative region wherein a plurality of illuminative elements is provided.
  • Embodiments of the invention are based on the inventive insight that the provision of at least one illuminative region with a plurality of illuminative elements on the back sheet, allows a caregiver to easily and quickly localize a baby or patient in emergency situations, especially in low light conditions and/or dark or dim environments.
  • the back sheet of the absorbent article such as a baby diaper or baby pants, is impervious to liquids (e.g., urine) and comprises one or more illuminative region(s), wherein these regions comprise multiple illuminative elements.
  • the illuminative elements are preferably provided according to an appealing design, for example in the shape of a sun, star, cloud, smileys, animals, geometrical shapes, etc.
  • the illuminative elements are preferably comprised of a phosphorescent and/or fluorescent substance that after being exposed to and charged with a light, such as daylight or normal room light, will uptake the energy.
  • Phosphorescence is a type of photoluminescence related to fluorescence.
  • the illuminative region with illuminative elements improve the general safety of the wearer.
  • the illuminative region with illuminative elements also contributes to the appeal and appearance of the absorbent article and/or improve an ease of use for a caregiver by assisting in the application and/or removal of the absorbent article to and/or from the wearer for example.
  • the illuminative elements When in darkness, the illuminative elements will glow and the caretaker can localize and observe for example new-borns wearing the absorbent article according to present invention, such as a diaper or pants, without turning on the lights. Clearly this is beneficial in emergency situations such as electricity blackouts or power interruptions where it is not possible to quickly generate light.
  • the glow slowly fades out and may glow up to 12 hours in a dark room.
  • the fluorescent substance glows under a UV light and in contrast to phosphorescent material, fluorescent materials stop emitting light within nanoseconds after the excitation radiation (UV light) is removed.
  • the at least one illuminative region covers at least 60% of the back sheet, more preferably at least 70% of the back sheet, even more preferably at least 80% of the back sheet.
  • the coverage of the at least one illuminative region allows for the absorbent article, especially the back sheet thereof, to be visually detectable from different angles, and regardless of an orientation of the absorbent article and/or the wearer thereof.
  • a larger illuminative region provides for an improved visibility of the absorbent article and its wearer and allows the absorbent article to be detected in low light or dark conditions from a front side, back side, bottom side, left side and/or right side thereof.
  • the illuminative region according to the invention can be defined as the smallest (imaginary) rectangle that encloses all illuminative elements.
  • the at least one illuminative region extends over at least 70% of a length of the back sheet, preferably over at least 80% of the length of the back sheet, more preferably over at least 90% of the back sheet, and most preferably over the entire length of the back sheet.
  • the extension of the at least one illuminative region allows for the absorbent article, especially the back sheet thereof, to be visually detectable from different angles, and regardless of an orientation of the absorbent article and/or the wearer thereof.
  • a longer illuminative region for an improved visibility of the absorbent article and its wearer, especially from a front and/or back side thereof.
  • the present invention relates to the absorbent article, wherein the at least one illuminative region are two illuminative regions, preferably three illuminative regions, more preferably four illuminative regions, most preferably five illuminative regions.
  • the absorbent article of present invention for example a diaper, when worn by an individual may comprise one or more illuminative regions on the front and one or more illuminative regions on the back of the diaper. In this manner the glow in the dark will be visible most of the time on both sides irrespective of the position of the individual that is wearing the diaper, thereby further improving visibility, guidance and increased awareness for the person fitting or removing the absorbent article to or from the wearer in low light conditions.
  • the plurality of illuminative elements covers between 1% and 20% of the at least one illuminative region, preferably between 2% and 18% of the at least one illuminative region, more preferably between 3% and 16% of the at least one illuminative region, and most preferably between 4% and 14%.
  • Experiments and cost estimations have shown that the improved visibility of the absorbent article in low light or dark conditions, occur already in case the plurality of illuminative elements covers at least 1 % of the at least one illuminative region, preferably at least 4%.
  • the plurality of illuminative elements that cover the at least one illuminative region should not exceed 20%, preferably not exceed 14%. Also above this 20% of illuminative elements that cover the at least one illuminative region the improved visibility, guidance and increased awareness for the person fitting or removing the absorbent article does not outweigh the increase in costs anymore.
  • the plurality of illuminative elements comprises distinct illuminative elements which are positioned at a distance from each other.
  • distinct illuminative elements positioned at a distance from each other visibility of the illuminative elements is increased since multiple high contrast sub-regions are created wherein illuminative elements are adjacent to, and preferably fully surrounded, by non-illuminative areas. In this manner the high contrast regions will be more easily detected by the human eye.
  • the provision of distinct illuminative elements positioned at a distance from each other allows to cover a relatively large area of the illuminative region with relatively little illuminative material, thereby on the one hand improving visibility, and on the other hand reducing costs.
  • illuminative elements may be in contact with each other, thereby forming a substantially continuous illuminative elements chain, which is surrounded by non-illuminative areas.
