Definitions

  • the present invention relates to folded, disposable incontinence diapers for incorporating body waste for preferred adult use.
  • Disposable incontinence diapers of this type are known and often have a main part (chassis) consisting of a front region, a back region and a crotch region lying between the legs of a user in the longitudinal direction of the diaper, the main part usually already comprising a liquid-absorbent absorbent body, and with rear side sections, so-called diaper ears, which are attached to both sides of the rear side longitudinal edges of the back area and are separate from one another and preferably provided with closure means, which extend in the transverse direction of the diaper beyond the rear side longitudinal edges of the main part and the front area and the back area when the diaper is in the applied state connect with each other.

  • this open diaper type is usually applied to the body in such a way that the rear side sections of the diaper overlap with an outside of the body in different degrees depending on the anatomical conditions
  • Disposable incontinence diapers are usually made in high-speed machines. Protruding components such as laterally protruding side sections can easily be damaged. Therefore, it is common to fold side portions of disposable incontinence diapers onto the chassis in the production process. In such cases, the side sections can easily be crumpled and folded in packaging processes. This often leads to the products appearing unsightly when unpacked by the user. In addition, the function of closure means attached to the side sections can be impaired by kinks. Since some user groups rely on the use of diapers of different sizes or suction strength, the dimensions are usually like
  • the extent in the hip circumference of disposable incontinence diapers is adapted to the body size and shape of different user groups. This can result in unfavorable differences in the packaging and logistics of diapers of different sizes, for example due to different dimensions of packaging.
  • W02007 / 058761A1 discloses absorbent articles with closure elements which are attached to diaper ears folded onto the chassis and which come to rest in the overlap area when the side edges of the chassis are folded in. This folding arrangement can lead to different gauge blocks for diapers of different sizes or diapers with diaper ears of different widths.
  • W02005 / 110321 A1 discloses an absorbent article which is folded in such a way that part of a respective diaper ear comes to protrude outwards and is easy to grasp. Protruding parts of the diaper ear could, however, be kinked during the packaging of the articles, which can have a disadvantageous effect, in particular, on the function of closure means attached in this area.

Abstract

L'invention concerne un arrangement comprenant des couches jetables pliées pour incontinence d'au moins une première taille et des couches jetables pliées pour incontinence d'une deuxième taille et des couches jetables pliées pour incontinence d'une troisième taille. Les couches jetables pour incontinence de la première taille (100) présentent une première envergure maximale MS1, les couches jetables pour incontinence de la deuxième taille présentent une deuxième envergure maximale MS2 et les couches jetables pour incontinence de la troisième taille présentent une troisième envergure maximale MS3, avec MS1≠MS2≠MS3 et MS1≠MS3. Les portions latérales arrière sont pliées sur elles-mêmes au niveau d'un nombre N d'axes de pliage de portion latérale qui s'étendent dans la direction longitudinale pour former un premier arrangement plié. Le premier arrangement plié des couches jetables pour incontinence de la première taille diffère du premier arrangement plié des couches jetables pour incontinence de la deuxième taille et du premier arrangement plié des couches jetables pour incontinence de la troisième taille par au moins une caractéristique. Ladite ou lesdites caractéristiques sont sélectionnées dans le groupe : nombre N d'axes de pliage de portion latérale au niveau desquels les portions latérales arrière (22) sont pliées sur elles-mêmes pour former le premier arrangement plié ; écart AB entre la ligne de pliage la plus extérieure du premier arrangement plié et une extrémité libre (41) d'une portion latérale arrière (22) respective ; envergure GF1 des couches jetables pour incontinence avec le premier arrangement plié ; largeur BF du premier arrangement plié.
