Description

2 0 presente invento diz respeito a uma fralda-calça ajustável e descartável, que uma vez colocada evita o escape de fezes e de urina.The present invention relates to an adjustable and disposable diaper pants which, once fitted, prevents leakage of feces and urine.

As realizações já conhecidas de fraldas ajustáveis têm como característica generalizada a de disporem de fios esticados ao longo das margens laterais da fralda, principalmente nas zonas que, quando a. fralda se acha em posição de uso, ficam situadas em torno das coxas do utilizador, aproximadamente á altura das virilhas. Esses fios estão situados entre as duas folhas exteriores da fralda, quer dizer, entre a folha permeável que se aplica contra o corpo do utilizador e a folha impermeável que fica situada na face oposta da fralda.The known embodiments of adjustable diapers generally have yarns stretched along the side edges of the diaper, especially in the areas where, diaper is in use position, are located around the user's thighs, approximately at the groin level. These wires are located between the two outer sheets of the diaper, ie between the permeable sheet which is applied against the wearer's body and the impermeable sheet which is situated on the opposite face of the diaper.

Esta solução resolve em grande parte o problema que consiste no facto da fralda ser capaz de reter a urina das crianças de tenra idade, mas de ser por vezes insuf.iciente para reter os excrementos, especialmente se estes estiverem no estado semilíquido, como á frequente acontecer no caso das crianças que usam f ra. 1 das-c a 1 c a.This solution largely solves the problem of the fact that the diaper is able to retain the urine of young children, but is sometimes insufficient to retain excreta, especially if they are in the semi-liquid state, as is often the case happen in the case of children who use medicine. 1 das-c to 1 c a.

Este problema foi resolvido em parte mediante fraldas--calça descartáveis que na proximidade das margens longitudinais da capa permeável da fralda que se aplica contra o corpo do utilizador apresentam unidas por intermédio de um dos seus bordos longitudinais umas bandas flexíveis dispostas longitudina1mente que adoptam uma forma semelhante a umas faixas que na zona do seu bordo longitudinal livre se encontram dotadas duns fios elásticos pré-esticados que vão constituir umas barreiras complementares aos fios elásticos que se acham alojados nos bordos longitudinais da fralda, destinadas a evitar a saída de líquidos ou excrementosThis problem has been solved in part by disposable diapers which in the vicinity of the longitudinal edges of the diaper permeable cap which is applied against the body of the wearer have, by means of one of its longitudinal edges, disposed longitudinally flexible flexible strips which adopt a shape similar to a strips which in the area of its free longitudinal edge are provided with pre-stretched elastic yarns which will constitute barriers complementary to the elastic threads which are housed in the longitudinal edges of the diaper, designed to avoid the exit of liquids or excrement

A experiência mostrou que.. no que diz respeito á eficácia de retenção de líquidos e de fases por parte das faixas, era possível conseguir~se melhores resultados aumentando o número de capas de que cada uma delas é constituída.Experience has shown that with regard to the effectiveness of retention of liquids and phases by the bands, it was possible to achieve better results by increasing the number of covers each of which are formed.

De acordo com as premissas expostas, foi concebida a fralda-calca descartável que constitui o objecto do invento, que é uma fralda-calca do tipo daquelas que compreendem uma envoltura formada por uma capa permeável que se aplica contra o corpo do utilizador e uma capa oposta impermeável, unidas entre si ao longo de linhas marginais, entre as quais se acha alojado um enchimento de natureza absorvente e retentora de líquidos, encontrando-se a referida fralda-calca também dotada, nalguns modelos de realização, duns fios elásticos pré-estiçados que vão ficar situados nas margens laterais da fralda-calça, encontrando™ -se na referida capa permeável incorporadas umas bandas flexíveis © resistentes que vão ficar dispostas longitudinalmente na proximidade das referidas margens, que apresentam as suas extremidades justapostas e unidas á capa permeável da fralda-calça e que vão ficar livres, com respeito á capa permeável da fralda-calça, em grande parte da sua largura, formando umas faixas salien tes que se acham dotadas de pelo menos uns fios elásticos previa-According to the foregoing assumptions, the disposable diaper-pant is the object of the invention, which is a diaper-pant of the type comprising a housing formed by a permeable cover that engages against the wearer's body and a cover by way of an absorbent and liquid-retentive filling, said diaper-pad also being provided in some embodiments with pre-stretched elastic yarns which are attached to each other along marginal lines, between which there is housed a filler of an absorbent and liquid- which are to be located on the side edges of the panty-diaper, said absorbent webs being incorporated in said permeable cap which are disposed longitudinally in the vicinity of said margins, which have their ends juxtaposed and joined to the permeable cap of the diaper and which will remain free, with respect to the permeable cap of the panty-diaper, to a large extent of its width, forming salient strips which are provided with at least one elastic yarns pre-
