Patent

CA 2214000

An enhanced flexibility fastener product (30) has a base (35) and hook elements (34a, 34b, 34c) integrally molded with and extending from the base (35). Hump-shaped formations (36a, 36b, 36c) (referred to as "rip stops"), that are integrally molded with base (35), are offset relative to the hook elements to reduce widthwise stiffness of the fastener product (30). The edge margins (31) of the fastener (30) are feathered in that they taper or otherwise reduce in thickness over an extended distance, preferably from at or near the hooks (34a, 34b, 34c) to the edge, resulting in a softer, less irritating fastener tape (30). Fasteners products according to the invention are particularly advantageous on disposable absorbent garments (10) such as diapers, sanitary napkins, and other articles of wear which come into contact with the user's skin.

Un système de fixation à flexibilité améliorée (30) a une base (35) et des crochets (34a, 34b, 34c) partant de la base (35). Des formations bosselées (36a, 36b, 36c) (auxquelles il est fait référence en tant que "saillies anti-déchirures") sont moulées d'une pièce avec la base (35) et sont décalées par rapport aux crochets pour diminuer la rigidité dans le sens de la largeur du système de fixation (30). Les bords (31) du système de fixation (30) sont réalisés de manière à se rétrécir (31) ou diminuer en épaisseur sur une distance importante, de préférence depuis les crochets (34a, 34b, 34c) ou leur voisinage jusqu'au bord, ce qui produit une bande de fixation (30) plus souple et moins irritante. Les dispositifs de fixation, selon l'invention, sont particulièrement avantageux pour des articles absorbants (10) à usage unique du type serviette hygiénique, couche pour bébé et autres articles qui viennent en contact avec la peau de l'utilisateur.
