  • Patent number: 6187990
    Abstract: 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.

  • Patent number: 5486168
    Abstract: A male incontinence guard includes an inner, liquid permeable casing layer; an outer, liquid impermeable casing layer; an absorbent pad having a first end and enclosed between said layers so as to include a first side edge on one side of said pad and a second side edge on an opposite side of said pad; said absorbent pad narrows at the first end; a first elastic device attached in a prestretched state to the inner casing layer and extends from the first end along at least a part of said first side edge; and a second elastic device attached in a prestretched state to the inner casing layer and extends from the first end along at least a part of said second side edge; said elastic devices arranged such that contraction of said elastic devices causes said inner casing layer at the first end of said pad to take a concave shape and said outer casing layer at said first end of said pad to take a convex shape.

  • Patent number: 5401266
    Abstract: An absorbent article intended for use as a urine-collecting insert in a diaper or an incontinence guard includes an inner casing layer (2) of liquid permeable material, which when the article is worn lies nearest the body of the wearer, an outer liquid permeable casing layer (3) and an absorbent pad (4) located between the casing layers. The outer casing layer (3) has a lower liquid permeability than the inner casing layer (2), such that liquid absorbed by the article is able to pass through the outer casing layer and absorbed by the diaper or incontinence guard, relatively slowly and in a controlled fashion.

  • Patent number: 5391160
    Abstract: A disposable absorbent article, such as a diaper or an incontinence guard, includes an inner liquid-permeable casing sheet which is positioned nearest the body of the wearer when the article is worn, an outer liquid-permeable casing sheet, and an absorbent pad enclosed between the inner and outer casing sheets. The absorbent pad includes, at least in the crotch part of the article, a hose-like body that is comprised of a shape-stable material having a very high liquid permeability. The hose-like body is generally centrally positioned in the article and extends in the longitudinal direction of the article. The hose-like body borders on the inner casing sheet and is surrounded by absorbent material on at least the side thereof remote from the inner casing sheet. The article can also include liquid barriers positioned on respective sides of the hose-like body.

  • Patent number: 5342337
    Abstract: The present invention relates to a disposable absorbent article, such as a diaper or an incontinence guard, which includes an inner liquid-permeable casing sheet (1), which lies the closest to the wearer's body when the article is in use, an outer liquid-impermeable casing sheet (2), and an absorbent body (3) which is enclosed between the two casing sheets. According to the invention, the absorbent pad (3) includes, at least in the region thereof which forms the crotch part when the article is worn, a hose-like body (5) which is made of a shape-stable material and which is highly permeable to liquid. The hose-like body is positioned centrally and extends in the longitudinal direction of the article and borders on the inner casing layer and is surrounded by absorbent material (4, 6) at least on the side thereof remote from the inner casing sheet.
