Abstract

fralda descartável é configurado de maneira que uma estrutura absorvente de líquido, tal como, um corpo absorvente, não se separe nas regiões frontal e traseira de cintura do corpo do usuário, e como um resultado, urina, etc, é impedida de vazar devido à formação de um intervalo entre o usuário e a estrutura absorvente de líquido. uma fralda (10) inclui um membro frontal de cintura (20), um membro traseiro de cintura (30) e um membro entrepernas (40). a superfície externa de uma estrutura absorvente de líquido (41) do membro entrepernas (40) é coberta com uma folha de cobertura externa (44), e juntas de vedação (50) e não-tecidos com bainha de barreira antivazamento (60) são formados pela folha de cobertura externa (44). linhas imaginárias de dobramento (65) se estendendo na direção longitudinal (y) são cada uma formada entre a borda mais próxima (62) e a borda mais distante (63) de um não-tecido com bainha de barreira antivazamento (60) e o não-tecido com bainha de barreira antivazamento (60) é dobrado junto à linha imaginária de dobramento (65) enquanto um membro elástico da barreira (64) não estiver em um estado esticado ou contraído. os não-tecidos com bainha de barreira antivazamento (60) são unidos nas porções frontal e traseira (45, 46) da estrutura absorvente de líquido (41) à uma folha de cobertura interna através de meios de junção, tal como, um agente adesivo, e isto forma as regiões de junção frontal e traseira (66, 67) se estendendo na direção longitudinal (y).disposable diaper is configured so that a liquid-absorbent structure, such as an absorbent body, does not separate in the front and rear waist regions of the user's body, and as a result, urine, etc., is prevented from leaking due to forming a gap between the user and the liquid-absorbing structure. a diaper (10) includes a front waist member (20), a rear waist member (30) and a crotch member (40). the outer surface of a liquid-absorbing structure (41) of the crotch member (40) is covered with an outer covering sheet (44), and sealing joints (50) and non-woven with anti-leakage sheath (60) are formed by the outer cover sheet (44). imaginary folding lines (65) extending in the longitudinal direction (y) are each formed between the nearest edge (62) and the furthest edge (63) of a nonwoven with anti-leakage barrier sheath (60) and the nonwoven with anti-leakage barrier sheath (60) is folded along the imaginary fold line (65) as long as an elastic barrier member (64) is not in a stretched or contracted state. non-woven fabrics with anti-leakage barrier sheaths (60) are joined in the front and rear portions (45, 46) of the liquid absorbent structure (41) to an internal covering sheet by means of joining means, such as an adhesive agent , and this forms the front and rear junction regions (66, 67) extending in the longitudinal direction (y).
