  • Absorbent Articles And Supports Therefor (AREA)

Abstract

Par omission de l'utilisation d'un intercalaire qui s'étend en ondulant vers l'extérieur en direction longitudinale à partir d'une feuille d'emballage après ouverture ou qui se froisse lors du pliage, on obtient des avantages tels qu'une amélioration des propriétés post-traitement d'une serviette hygiénique usagée. Un article absorbant (1), qui est plié en quatre ou plus en direction longitudinale et ainsi individuellement conditionné, comprend des rabats de type aile (W) et des rabats maintenant les hanches (WB) placés sur les deux côtés qui sont chacun pliés sur la face latérale d'une feuille de surface (3), un intercalaire (11) pour couche adhésive sensible à la pression destiné à empêcher le mauvais alignement d'une aile qui recouvre de façon libérable une paire de couches adhésives sensibles à la pression (8) afin d'empêcher le mauvais alignement d'une aile, et un intercalaire (12) pour couche adhésive sensible à la pression destiné à empêcher le mauvais alignement avec la hanche qui recouvre de façon libérable une paire de couches adhésives sensibles à la pression (8B) destinées à empêcher le mauvais alignement avec la hanche, les intercalaires (11, 12) étant placés chacun à la position intermédiaire des lignes de pli, et l'intercalaire (12) étant collé à la face interne d'une feuille d'emballage (10) s'étendant vers l'arrière à partir de l'article absorbant (1) tandis que l'intercalaire (11) est collé à la face extérieure de la feuille d'emballage (10).
