Abstract

L'invention porte sur un produit jetable absorbant l'urine, comprenant une partie de corps principal de type feuille ayant une forme approximativement rectangulaire et un élément élastique s'étendant d'une extrémité latérale de la partie de corps principal à l'autre extrémité latérale à travers une extrémité antérieure. Dans le produit jetable absorbant l'urine, l'élément élastique, fixé à la partie de corps principal dans l'état où l'élément élastique est déployé, se contracte au niveau des côtés gauche et droit et du côté antérieur d'un cœur absorbant, et il en résulte que la paire d'extrémités latérales et l'extrémité antérieure de la partie de corps principal s'orientent vers le haut à la périphérie de la partie antérieure du cœur absorbant et qu'une poche destinée à contenir l'extrémité du pénis du porteur se forme d'elle-même sur la partie antérieure du cœur absorbant. De la manière ci-dessus, il est possible de recouvrir les organes génitaux mâles par une structure simple faite dans le produit jetable absorbant l'urine.
