Definitions

  • the present invention relates to an absorbent article, such as a diaper or an openable and re-closable pants-type diaper, comprising first and second sides which when the article is worn are intended to lie proximal to and distal from the wearer's body respectively, first and second end-parts which when the article is worn are intended to lie respectively against the front-part and the rear-part of the wearer, and a crotch part which is located between said two end-parts and which when the article is worn is intended to be located between the wearer's thighs, wherein the article further comprises a fastener system by means of which the end-parts of the article can be brought together to an assembled or closed pants-like configuration from a non-assembled or open configuration or which enables the end-parts to be loosened from an assembled or closed pants-like configuration to a non-assembled or open configuration, wherein the fastener system includes mutually coacting fastener devices, wherein the article includes two side-edges which in the non-assem ⁇

It is particularly preferred to apply the invention with absorbent articles that are intended for one-time use only.
  • Absorbent articles such as child and adult diapers have long been provided with fastener systems by means of which the user or the user's nurse, minder, can bring different parts of the diaper, for instance the front and rear parts of the diaper, into more or less close abutment with the user's body, so that the diaper will take a pants-like configuration around the wearer's body.
  • the fastener system can also be released, to enable the diaper to be removed after use.
  • Example ⁇ of such fastener systems include individual pants or a triangular sheet which supports an absorbent insert so that said insert will face towards the wearer's body in use.
  • fastener systems include article-mounted fastener devices by means of which the front and the rear parts of the article can be joined together.
  • fastener systems are adhesive coatings and mechanical fastener devices. These latter devices may, for instance, consist in press studs, buttons and button holes or so-called touch-and- close fasteners, ie loop and hook fasteners.
  • Both adhesive and mechanical fastener devices may be provided on fastener tabs mounted on the article, suitably in the vicinity of it ⁇ two corner parts.
  • the diaper according to SE 446 056 is also provided with one or more plastic strip ⁇ mounted on the end of the diaper oppo ⁇ ite the end on which the fastener tabs are arranged.
  • the plastic strip or pla ⁇ tic strips are used a ⁇ an anchorage surface for securing the fastener tabs.
  • the nature of the plastic strip is such as to enable the fastener tabs to be released therefrom without damaging the adhe ⁇ ive coating on the fa ⁇ tener tab ⁇ or the plastic strip. This enables the fastener tab ⁇ to be refastened to the pla ⁇ tic strip, for instance after having opened the diaper to see whether or not it needs to be changed.
  • This fastener system has the added advantage of enabling a removed, ⁇ oiled diaper to be rolled up, folded or packaged in ⁇ ome other way with the pla ⁇ tic backing ⁇ heet facing outwards and to be effec ⁇ tively secured and sealed with the aid of the fastener system, so that no urine or faeces are able to escape from the packaged diaper. Since a diaper in this state is not intended for further use, it is not necessary to ensure that the fastener tabs can be released undamaged more than once.
  • the adhesive fastener tabs can be fastened to any suitable part of the diaper backing sheet whatsoever, and thus also surfaces from which the fa ⁇ tener tabs cannot be loosened without causing damage to the backing sheet or to the adhesive coating on the fastener tabs.
  • the propo ⁇ ed ⁇ olution to this problem is to be provide the article with disposal means which enable the article to be closed and sealed in a "disposal state".
  • the disposal means can have different forms. According to one preferred embodiment, an extra fa ⁇ tener device i ⁇ mounted on the rear ⁇ ide of at least one of the fastener tab ⁇ , ⁇ o a ⁇ to enable the extra fastener device to be fastened to the front side of the other fastener tab, after bringing the article to a "disposal state".

  • a diaper according to EP 0235014 Bl can, of course, be closed and secured in a rolled-up state after use, but only when the diaper is rolled-up from the end in which the hook and loop fastener tabs are mounted.
  • the loop and hook receiving strip or strips will be acces ⁇ ible to the hook and loop device ⁇ .
  • the same diaper may, of course, also be closed after use, by fastening the hook and loop devices to the receiving strip in the same manner as that applied when the diaper is donned.
  • An object of the present invention is to provide an improved mechanical absorbent-article fastening system.
  • Another object of the present invention is to ⁇ olve the problem of clo ⁇ ing an ab ⁇ orbent article with the aid of a mechanical fa ⁇ tener ⁇ y ⁇ tem both during use and after use.
