Abstract
An absorbent article is disclosed which contains an absorbent positioned between a fluid permeable cover and a fluid-impermeable baffle. The baffle can be either a nonwoven web or have a nonwoven web secured to it. The nonwoven web hs a high coefficient of friction so as to hold the absorbent article stationary relative to an adjacent undergarment and thereby retain the absorbent article in a comfortable position relative to the body of the user. The nonwoven web is a dry, soft, non-tacky, fibrous material which can have an elastomeric component. The nonwoven web can partially or totally cover the exterior surface of the absorbent article which is away from the body of the user.
Claims27
An absorbent article comprising first and second members cooperating to enclose an absorbent, one of said members being a fibrous, nonwoven web having an external frictional surface with a Sheffield smoothness rating of greater than 400, said frictional surface assisting in retaining said absorbent article in a desired position.
An absorbent article designed to contact a human body and be retained in place by an undergarment, said article comprising:
- (a) first and second members cooperating to enclose an absorbent;
- and
- (b) nonwoven means for retaining said absorbent article in frictional contact with said undergarment, said nonwoven means being secured to one of said members and having a frictional surface with a Sheffield smoothness rating of greater than 400.
An absorbent article designed to contact a human body and be retained in place by an undergarment, said article comprising:
- (a) a fluid-permeable cover;
- (b) a fluid-impermeable baffle;
- (c) an absorbent enclosed by said cover and said baffle;
- and
- (d) nonwoven means for retaining said absorbent article in frictional contact with said undergarment, said nonwoven means being secured to said baffle and having an external frictional surface with a Sheffield smoothness rating of greater than 400.
An absorbent article designed to contact a human body and be retained in place by an undergarment, said article comprising:
- (a) an absorbent having first and second surfaces;
- (b) a fluid-permeable cover positioned adjacent to said first surface of said absorbent;
- (c) a fluid-impermeable baffle positioned adjacent to said second surface of said absorbent, said baffle and cover cooperating to enclose said absorbent;
- and
- (d) nonwoven means for retaining said absorbent article in frictional contact with said undergarment, said nonwoven means being secured to said baffle and having an external frictional surface with a Sheffield smoothness rating of greater than 400.
An absorbent article designed to contact the perineum of a human body, said article comprising:
- (a) an absorbent having first and second surfaces;
- (b) a fluid-permeable cover positioned adjacent to said first surface of said absorbent;
- (c) a fluid-impermeable baffle positioned adjacent to said second surface of said absorbent, said baffle and cover cooperating to enclose said absorbent;
- and
- (d) nonwoven means for retaining said absorbent article in a desired position relative to said perineum, said nonwoven means being an elastomeric web secured to said baffle and having an external frictional surface with a Sheffield smoothness rating of greater than 400 and a coefficient of friction of greater than about 2.
An absorbent article designed to contact the perineum of a human body, said article comprising:
- (a) an absorbent having first and second surfaces;
- (b) a fluid-permeable cover positioned adjacent to said first surface of said absorbent;
- (c) a fluid-impermeable baffle positioned adjacent to said second surface of said absorbent, said baffle and cover cooperating to enclose said absorbent;
- and
- (d) nonwoven means for retaining said absorbent article in a desired position relative to said perineum, said nonwoven means being a fibrous elastomeric web secured to said baffle and having an external frictional surface with a Sheffield smoothness rating of greater than about 400.
An absorbent article designed to contact the perineum of a human body, said article comprising:
- (a) a fluid-permeable cover;
- (b) a fluid-impermeable baffle;
- (c) an absorbent positioned between and enclosed by said cover and said baffle to form a pad having a pair of outwardly extending wings;
- and
- (d) fibrous nonwoven means for retaining said pad in a desired position relative to said perineum, said nonwoven means being secured to said baffle and having an external frictional surface with a Sheffield smoothness rating of greater than about 400.
A method of retaining an absorbent article in a desired position relative to the perineum of a human body, said absorbent article having a cover, a baffle, and an absorbent positioned between and enclosed by said cover and said baffle, and a nonwoven web secured to said baffle, said nonwoven web having an external frictional surface with a Sheffield smoothness rating of greater than about 400, said method comprising the steps of:
- (a) placing said absorbent article adjacent to said human body with said cover contacting said perineum;
- and
- (b) positioning an undergarment around said perineum;
- and
- (c) contacting said undergarment with said frictional surface of said nonwoven web whereby said absorbent article is held stationary relative to said undergarment.
An absorbent article comprising:
- (a) an absorbent having first and second surfaces;
- (b) a fluid-permeable cover attached to said first surface of said absorbent;
- and
- (c) a nonwoven, fluid-impermeable web attached to said second surface of said absorbent and cooperating with said cover to enclose said absorbent, said web having an external frictional surface with a Sheffield smoothness rating of greater than about 400.
