Abstract

Disposable diapers provided with breathable leg cuffs. Disposable diapers comprise a topsheet, an absorbent element, and a backsheet. The leg cut of a disposable diaper is that part of the diaper which fits about the wearer's leg. Extensions of the backsheet can be used to form cuffs which are frequently elasticized. In the present invention the cuffs are formed of a material which allows passage of vapor ("breathes") while tending to retard the passage of liquid. Apertured thermoplastic films are examples of such materials. Certain advantages accrue in cuffs which are permeable to vapor in their distal portions and impermeable in the portions adjacent the absorbent element. If the disposable diaper has a breathable backsheet, the cuffs are constructed to be more permeable to vapor per unit area in their breathable portions than is the backsheet.

Claims11

Dependent claims

A disposable diaper comprising:

a liquid impermeable backsheet;
a liquid pervious topsheet secured to said backsheet;
an absorbent element interposed between said topsheet and said backsheet;
a pair of longitudinally extending stand-up breathable cuffs, each of said cuffs having a fixed edge and a distal edge spaced from said fixed edge, each of said cuffs having said fixed edge attached to the diaper, said distal edge being unsecured to at least a portion of the diaper, wherein each of said cuffs is permeable to vapor over at least a portion of its extent;
and
an elastic element operatively associated with said distal edge of each of said cuffs and affixed in an elastically contractable condition to said cuff to render said distal edge of said cuff elastically contractable so that said elastic elements effectively contracts or gathers the cuff material adjacent said elastic element so that said distal edge is displaced inwardly from said fixed edge and away from said topsheet.
