Title
(EN) SANITARY NAPKIN COMPRISING THREE-DIMENSIONALLY SHAPED TUBE OF ABSORBENT MATERIAL
(FR) SERVIETTE HYGIENIQUE COMPORTANT UN TUBE DE FORME TRIDIMENSIONNELLE EN MATIERE ABSORBANTE
Abstract
(EN)
A tube of absorbent material extends outward from the body-facing side of the base pad and is aligned along the longitudinal centerline of the base pad. In one embodiment, the tube of absorbent material comprises an absorbent material and a cover at least partially wrapping the absorbent material. In this embodiment, the absorbent material is penetrated by autogenous bonds that join one portion of the cover to an opposing portion of the cover. The bonds are selectively placed to provide the tube of absorbent material with a distinct three-dimensional shape. The method of making a shaped tube of absorbent material for the sanitary napkin, in one embodiment, involves the steps of: (a) providing a web of absorbent material; (b) providing a cover for the first and second surfaces of the web of absorbent material; (c) at least partially covering the first and second surfaces of the web of absorbent material with the cover to form a composite web having longitudinal side margins; (d) folding the composite web at least once with folds defining fold lines that are arranged about the longitudinal centerline of the web of absorbent material; and (e) autogenously bonding a portion of the cover that covers the first surface of the web of absorbent material to a portion of the cover that covers an opposing portion of the second surface of the web of absorbent material.

La présente invention concerne un tube de matière absorbante se présentant extérieurement par rapport à la face anatomique du matelas de base, aligné sur la ligne médiane longitudinale du matelas de base. Selon une réalisation, le tube de matière absorbante est constitué de matière absorbante et d'un voile enveloppant au moins partiellement la matière absorbante. Selon cette réalisation, la matière absorbante est pénétrée de liaisons autogènes établies d'une partie du voile à une partie opposée du voile. Ces liaisons sont disposées de façon sélective de façon à conférer au tube de matière absorbante une forme tridimensionnelle distincte. Le procédé de réalisation du tube formé de matière absorbante dans le cas de serviettes hygiéniques comporte plusieurs temps. (a) On commence par prendre une nappe de matière absorbante. (b) On prend ensuite un voile destiné à la première et à la seconde face de la nappe de matière absorbante. (c) On recouvre au moins partiellement la première et la seconde face de la nappe de matière absorbante avec ce voile de façon à former une nappe composite comportant des bords marginaux longitudinaux. (d) On plie la nappe composite au moins une fois de façon que les plis définissent des lignes de pli
