Abstract
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.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
161 words
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.
Claim 2
Dependent Claim
161 words
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.
Claim 3
Dependent Claim
17 words
The disposable diaper of claim 1 wherein each of said fixed edges is attached to said topsheet.
Claim 4
Dependent Claim
16 words
The disposable diaper of claim 2 wherein said cuffs are each formed unitarily with said topsheet.
Claim 5
Dependent Claim
20 words
The disposable diaper of claim 2 wherein said cuffs are each formed by a separate element affixed to said topsheet.
Claim 6
Dependent Claim
14 words
The disposable diaper of claim 1 wherein said cuffs are vapor and liquid permeable.
Claim 7
Dependent Claim
25 words
The disposable diaper of claim 1 wherein said cuffs are vapor permeable but liquid impermeable, said cuffs being more permeable to vapor than said backsheet.
Claim 8
Dependent Claim
19 words
The disposable diaper of claim 1 wherein said cuff comprises a vapor permeable portion and a vapor impermeable portion.
Claim 9
Dependent Claim
33 words
The disposable diaper of claim 7 wherein said vapor permeable portion is positioned adjacent said distal edge and said vapor impermeable portion is positioned intermediate said vapor permeable portion and said fixed edge.
Claim 10
Dependent Claim
21 words
The disposable diaper of claim 8 wherein said vapor permeable portion comprises from about 5% to about 75% of said cuff.
Claim 11
Dependent Claim
31 words
The disposable diaper of claim 1 wherein said absorbent element has longitudinal side margins, said cuffs being affixed to said diaper inward from said longitudinal side margins of said absorbent element.
Claim 12
Dependent Claim
15 words
The disposable diaper of claim 10 wherein said absorbent element has a generally hourglass configuration.
