Estimating the term…
The invention relates to absorbent articles, such as diapers and like articles and is concerned with methods for preventing undesirable odors and/or preventing the growth of undesirable microorganisms when the articles are in use, and also provides an absorbent article which can be worn for long periods of time without generating undesirable odors, incurring the risk of infection or having a negative effect on skin. Another object is to amplify the presence in the wearer's urogenital zone of microbiological flora that will assist in preventing the occurrence of urinal tract infections. These objects have been achieved by adding to the absorbent articles microorganisms which exhibit antagonistic properties against present undesirable strains of microorganisms, so as to restrain the growth of these or establishing of new undesirable species.
In an absorbent diaper including added microorganisms, the improvement wherein the added microorganisms are selected from genera Lactobacillus or Lactococcus, and exhibit, when the absorbent diaper is worn regularly by a wearer for a short or longer period, antagonistic properties against undesirable strains of microorganisms from the families Enterobacteriaceae, Micrococcaseae, Psuedomonadaceae and Ascomycetes and the genus Streptococcus, and present or arising in the absorbent diaper or in the urogenital zone of the wearer of said absorbent diaper;
In an absorbent diaper comprising a permeable outer sheet which in use is intended to lie proximal to a wearer, a liquid-impermeable backing sheet which in use is intended to lie distal from the wearer, and an absorbent structure positioned between the outer sheet and the backing sheet, the absorbent diaper including added microorganisms, the improvement wherein the added microorganisms are selected from genera Lactobacillus or Lactococcus, and exhibit, when the absorbent diaper is worn regularly for a short or longer period, antagonistic properties against undesirable strains of microorganisms from the families Enterobacteriaceae, Micrococcaseae, Psuedomonadaceae and Ascomycetes and the genus Streptococcus, and present or arising in the absorbent diaper or in the urogenital zone of the wearer;
In an absorbent diaper including added microorganisms, the improvement wherein the added microorganisms are selected from the group consisting of Lactobacillus acidophilus, Lactobacillus curvatus, Lactobacillus plantarum, and Lactococcus lactis, and exhibit, when the absorbent diaper is worn regularly by a wearer, antagonistic properties against undesirable strains of microorganisms selected from the group consisting of Proteus mirabilis, Proteus vulgaris, Escherichia coli, Candida albicans, and the genera Klebsiella, Enterococcus, Staphylococcus, Streptococcus and Pseudomonas, said strains of microorganisms being present or arising in the absorbent diaper or in the urogenital zone of the wearer of said absorbent diaper;
