A surface fastener comprises a first substrate sheet having on its front surface hook-shaped engaging elements and on its rear surface a low-adhesion adhesive double coated tape to an outer surface of which a backing sheet is adhered, and a second substrate sheet having on its front surface loop-shaped engaging elements and on its rear surface an adhesive layer to an outer surface of which a peel paper is adhered. For attaching the surface fastener to a paper diaper, the adhesive layer of the second substrate sheet is adhered to a front covering portion of the diaper, while the adhesive double coated tape of the first substrate sheet is adhered to an attachment strip of a hip covering portion of the diaper after the backing sheet is peeled off. When casting off the diaper after using, the adhesive double coated tape is separated from the first substrate sheet so as to be left on the attachment strip and then the diaper is folded, whereupon the adhesive double coated tape on the attachment strip is adhered to an outer surface of the folded diaper to wrap up the diaper.
Cette invention concerne une languette d'attache formée d'un premier support comportant, sur sa face antérieure, des éléments d'accrochage en forme de crochet et, sur sa face postérieure, un ruban adhésif double face à faible adhésivité dont la surface libre reçoit une pellicule de protection; et d'un second support comportant, sur sa face antérieure, des éléments d'accrochage en forme de boucle et, sur sa face postérieure, une couche adhésive qui porte une pellicule pelable. Pour fixer la languette d'attache à une couche en papier, la couche adhésive du second support est appliquée contre le devant de la couche tandis que la bande adhésive double face du premier support est placée, une fois la pellicule pelable enlevée, sur une bande de fixation disposé sur la partie de la couche couvrant la hanche du porteur. Au moment de jeter la couche souillée, on sépare la bande adhésive double face du premier support de façon qu'elle demeure collée à la bande de fixation de la couche, on plie la couche puis on colle la bande adhésive double face sur la face extérieure de la couche pliée pour former paquet fermé.
